Overview


We are a clinical-stage biotechnology company that discovers and develops Anticalin-based drugs to target validated disease pathways in unique and transformative ways. Our clinical pipeline includes elarekibep, formerly referred to as PRS-060/AZD1402, an inhaled IL-4R? antagonist Anticalin protein to treat uncontrolled asthma, PRS-220, an inhaled CTGF antagonist to treat IPF and other forms for fibrotic lung disease, an immuno-oncology, or IO, bispecific PRS-344/S095012 targeting PD-L1 and 4-1BB. Proprietary to us, Anticalin proteins are a novel class of therapeutics validated in the clinic and through partnerships with leading pharmaceutical companies. In particular, we have alliances with AstraZeneca and Genentech to treat respiratory diseases, with Genentech also in ophthalmology and with Servier, Seagen, and Boston Pharmaceuticals in IO. Our discovery and development programs are in varying stages and include:





  • Elarekibep, our lead respiratory program partnered with AstraZeneca for the
    treatment of asthma, is a drug candidate that antagonizes IL-4R?, thereby
    inhibiting the downstream action of IL-4 and IL-13, two cytokines known to be
    key mediators in the inflammatory cascade that drive the pathogenesis of
    asthma and other inflammatory diseases.




  • Elarekibep was tested in a nebulized formulation and an IV arm for
    pharmacokinetic, or PK, assessment in 54 healthy volunteers at nominal dose
    levels ranging from 0.25 mg to 400 mg in a phase 1 single-ascending dose, or
    SAD, study. Data from that study were presented at the American Thoracic
    Society International Conference in May 2019 showing that elarekibep was
    well-tolerated when given as single inhaled or intravenous doses to healthy
    volunteers and there was systemic target engagement (as measured by pSTAT6
    inhibition). Elarekibep was also tested in a phase 1 multiple-ascending dose,
    or MAD, study in 30 patients that were randomized to receive delivered doses
    via nebulizer ranging from 2 mg to 60 mg (5 mg to 150 mg nominal dose) twice
    daily for nine consecutive days and one final dose on the 10th day, and 12
    patients were randomized to receive placebo at the same intervals. We
    presented interim data from the elarekibep phase 1 MAD study at the European
    Respiratory Society International Congress in October 2019 and reported that
    elarekibep was well-tolerated at all doses, led to a statistically significant
    reduction in FeNO, a validated biomarker for eosinophilic airway inflammation,
    and showed dose-dependent systemic target engagement in patients with mild
    asthma and elevated levels of FeNO (? 35ppb).




  • The phase 2a asthma study is ongoing at multiple sites globally. This phase 2a
    study is a two-part, multi-center, placebo-controlled clinical study of
    elarekibep that will evaluate elarekibep at up to three dose levels using a
    dry powder formulation administered twice daily. In part 1a (1 mg and 3 mg
    dose safety) of the study, 31 asthma patients, controlled on standard of care
    (medium dose inhaled corticosteroids, or ICS, with long-acting beta agonists,
    or LABA), received elarekibep twice daily over four weeks to establish the
    safety profile and pharmacokinetics of the dry powder formulation of
    elarekibep. A safety review following completion of part 1a included an
    evaluation, compared to placebo, of the incidence of adverse events, changes
    in laboratory markers (immuno-biomarkers, clinical chemistry, and hematology),
    and forced expiratory volume in one second, or FEV1. Following the safety
    review, AstraZeneca began enrollment of part 2a (1 mg and 3 mg dose efficacy)
    of the study to evaluate efficacy, safety, and pharmacokinetics of elarekibep
    administered twice daily to asthma patients, uncontrolled on medium dose ICS
    with LABA, that have a blood eosinophil count of ? 150 cells/?L and FeNO ? 25
    ppb in the 1 mg and 3 mg arms and a placebo arm. Following a four-week run-in
    period, patients will be dosed and monitored over four weeks. FEV1 improvement
    at four weeks compared to placebo will be the primary endpoint in this portion
    of the study. Also following the safety review, AstraZeneca initiated part 1b
    of the study to evaluate the safety of the 10 mg dose in asthma patients
    controlled on standard of care who will receive elarekibep twice daily over
    four weeks, and part 1b has now completed enrollment. In the second quarter of
    2022, AstraZeneca conducted a reforecast of the study, which has taken into
    account the global challenges of recruiting for respiratory clinical trials
    caused by the continued impact of the COVID-19 pandemic, and
    has broadened enrollment criteria in part 2 (previously referenced as part
    2a) of the study to facilitate recruitment of the study. AstraZeneca also now
    plans to focus part 2 on the 3 mg cohort for the efficacy readout and plans to
    stop enrollment for the 1 mg cohort. AstraZeneca no longer plans to enroll the
    10 mg cohort for the efficacy readout (previously referenced as part 2b).

    Topline data from part 2 of this study are expected to be reported by the
    middle of 2024.




  • Upon receipt of the topline data and notice from AstraZeneca, including a
    product development plan and budget, we will have 30 days to opt into
    co-development of the program with AstraZeneca at one of two levels, neither
    of which includes an option exercise fee. If we do not choose to participate
    in co-development, we would still be entitled to sales royalties from
    single-digit up to the mid-teens, plus the potential for more than $1 billion
    in sales milestones. At the first opt-in level, we would be responsible for
    25% of the cost-share through regulatory approval with a predetermined cost
    cap. At this level, for the lifetime of this product, we would receive sales
    royalties from single-digit up to the high teens, plus the potential for
    multi-billion dollar sales milestones. The second opt-in level would be at a
    50% cost share without a cost cap which, instead of sales royalties and
    milestones, would result in a gross margin share in the mid-twenty percent
    range for the lifetime of the product. We also have a separate option to
    co-commercialize elarekibep with AstraZeneca in the United States independent
    of the co-development opt-in decision.




  • There are currently two discovery-stage programs included in the AstraZeneca
    alliance beyond elarekibep, the targets and disease areas of which are
    undisclosed. Pieris retains co-development and U.S. co-commercialization
    options for the two discovery-stage programs.




  • Our lead fully proprietary respiratory asset, PRS-220, an oral inhaled
    Anticalin protein targeting connective tissue growth factor, or CTGF, is being
    developed as a local treatment for idiopathic pulmonary fibrosis, or IPF, and
    other forms of fibrotic lung disease. CTGF, a matricellular protein, is a
    driver of fibrotic tissue remodeling and the protein has been found
    over-expressed in lung tissue from patients suffering from IPF. Clinical data
    from a phase 2 study with pamrevlumab conducted by Fibrogen indicated that
    inhibition of CTGF reduced the decline in lung function in patients, thus
    demonstrating clinical proof of concept for this target.




  • In 2021, we received a €14.2 million grant from the Bavarian Ministry of
    Economic Affairs, Regional Development and Energy supporting research and
    development of the PRS-220 program.




                                       94

  • We presented initial preclinical data for PRS-220 at the European Respiratory
    Society International Congress 2021 demonstrating a more potent and durable
    target engagement profile compared to a clinical-stage, systemically delivered
    anti-CTGF antibody benchmark. Additionally, the targeting of CTGF locally in
    the lung showed increased attenuation of fibrotic lung remodeling in
    vivo compared to the systemically delivered antibody. This outcome correlates
    with superior lung tissue exposure of PRS-220 compared to that of the
    systemically administered antibody in head-to-head studies, where
    intratracheally administered PRS-220 efficiently penetrates the fibrotic,
    interstitial lung tissue of mice.




  • We are conducting a phase 1 study of PRS-220 in healthy volunteers in
    Australia. The study is a randomized, two-part, blinded, placebo-controlled
    study, designed to assess the safety, tolerability, pharmacokinetics, and
    immunogenicity of single and multiple ascending doses of PRS-220 when
    administered by oral inhalation to healthy subjects. We expect to report the
    outcome of the study later this year.




  • In May 2021, we also entered into a multi-program research collaboration and
    license agreement with Genentech, a member of the Roche Group, to discover,
    develop and commercialize locally delivered respiratory and ophthalmology
    therapies. We are currently conducting joint discovery activities in each of
    the two committed programs.




  • PRS-400 is a fully proprietary Anticalin protein targeting Jagged-1 and is
    being developed as a local treatment for muco-obstructive lung diseases.
    Jagged-1 is one of five cell surface ligands interacting with Notch receptors.
    It has been demonstrated that Jagged-1/Notch signaling drives secretory cell
    trans-differentiation in the airways and that blocking Jagged-1/Notch
    signaling reduces secretory cell number, mucin expression and mucus
    plugging in vivo. In August 2022, we presented preclinical data at the
    European Respiratory Society International Congress 2022 indicating that
    candidate molecules inhibit Jagged-1-induced Notch 2 signaling in a
    dose-dependent manner and also demonstrate that PRS-400 reduces mucin
    expression ex vivo. Additionally, PRS-400 was found in vivo to reduce mucin
    gene expression and goblet cells in mice with IL-13-induced airway
    inflammation. These findings suggest that PRS-400 represents a promising
    opportunity to address muco-obstructive respiratory diseases locally with an
    attractive therapeutic index.




  • Cinrebafusp alfa is a bispecific Mabcalin compound comprising a HER2-targeting
    antibody genetically linked to 4-1BB-targeting Anticalin proteins. Cinrebafusp
    alfa is designed to drive tumor localized T cell activation through
    tumor-targeted drug clustering mediated by HER2 expressed on tumor cells. This
    program was the first 4-1BB bispecific T cell co-stimulatory agonist to enter
    clinical development.




  • In July 2022, we received fast track designation from FDA for cinrebafusp
    alfa. In August 2022, we announced the decision to cease further enrollment in
    the two-arm, multicenter, open-label phase 2 study of cinrebafusp alfa as part
    of a strategic pipeline prioritization to focus our resources. Cinrebafusp
    alfa has demonstrated clinical benefit in phase 1 studies, including single
    agent activity in a monotherapy setting, and in the phase 2 study in
    HER2-expressing gastric cancer, giving the Company confidence in its broader
    4-1BB franchise.




  • PRS-344/S095012 is a bispecific Mabcalin protein compound comprising a
    PD-L1-targeting antibody genetically linked to 4-1BB-targeting Anticalin
    proteins. PRS-344/S095012 is being developed as part of our IO collaboration
    with Servier.




  • The first patient in phase 1/2 study of PRS-344/S095012 was dosed in November
    2021 and the study is being conducted in multiple countries, including the
    United States.




  • The first-in-human phase 1/2 multicenter open-label dose escalation study is
    designed to determine the safety and preliminary activity of PRS-344/S095012
    in patients with advanced and/or metastatic solid tumors. We plan to present
    the escalation data at a medical meeting in 2023.




  • Pieris and Servier presented preclinical data and the phase 1/2 study design
    at the American Association for Cancer Research, or AACR, medical meeting in
    April 2022.




  • We expect to initiate the expansion cohorts in a select number of jointly
    vetted indications later this year.




  • Our IO portfolio also includes additional drug candidates beyond
    PRS-344/S095012 that are multi-specific Anticalin-based fusion proteins
    designed to engage immunomodulatory targets, comprising a variety of
    multifunctional biotherapeutics. Other IO drug candidates are being developed
    as part of our collaborations with Servier, Seagen, and Boston
    Pharmaceuticals.




  • We have already handed one of the programs in the Seagen collaboration,
     SGN-BB228 (also referenced as PRS-346), a CD228 x 4-1BB bispecific
    antibody-Anticalin compound, over to Seagen, who is responsible for further
    advancement and funding of the asset. In January 2023, the first patient was
    dosed in a Seagen-sponsored phase 1 study of  SGN-BB228, upon which we
    achieved a $5.0 million milestone. Seagen presented preclinical data for this
    program at the Society for Immunotherapy of Cancer 37th Annual Meeting in
    November 2022. The program is one of three programs in the Seagen alliance,
    and we believe the previous achievement of a key development milestone for
    this program validates our approach and leadership in IO bispecifics,
    complementing the encouraging clinical data seen with cinrebafusp alfa. During
    the third quarter of 2021, we initiated the second program, and during the
    fourth quarter of 2022, we initiated the third program within the
    collaboration with Seagen. We retain a co-promotion option for one program in
    the Seagen collaboration in the United States.




  • PRS-342/BOS-342 is a 4-1BB/GPC3 bispecific Mabcalin compound that we have
    exclusively licensed to Boston Pharmaceuticals. Boston Pharmaceuticals
    continues to advance PRS-342/BOS-342 towards the clinic, with phase 1 expected
    in the coming months.



Since inception, we have devoted nearly all of our efforts and resources to our research and development activities and have incurred significant net losses. For the years ended December 31, 2022 and 2021, we reported net losses of $33.3 million and $45.7 million, respectively. As of December 31, 2022, we had an accumulated deficit of $290.4 million. We expect to continue incurring substantial losses for the next several years as we continue to develop our clinical and preclinical drug candidates and programs. Our operating expenses are comprised of research and development expenses and general and administrative expenses.

We have not generated any revenues from product sales to date, and we do not expect to generate revenues from product sales for the foreseeable future. Our revenues for the fiscal years ended December 31, 2022 and 2021 were from license and collaboration agreements with our partners.

A significant portion of our operations are conducted in countries other than the United States. Since we conduct our business in U.S. dollars, our main exposure, if any, results from changes in the exchange rates between the euro and the U.S. dollar. At each period end, we remeasure assets and liabilities to the functional currency of that entity (for example, U.S. dollar payables recorded by Pieris Pharmaceuticals GmbH). Remeasurement gains and losses are recorded in the statement of operations line item 'Other income (expense), net'. All assets and liabilities denominated in euros are translated into U.S. dollars at the exchange rate on the balance sheet date. Revenues and expenses are translated at the weighted average rate during the period. Equity transactions are translated using historical exchange rates. All adjustments resulting from translating foreign currency financial statements into U.S. dollars are included in accumulated other comprehensive income (loss).

Key Financial Terms and Metrics

The following discussion summarizes the key factors our management believes are necessary for an understanding of our consolidated financial statements.





Revenues


We have not generated any revenues from product sales to date and we do not expect to generate revenues from product sales for the foreseeable future. Our revenues for the last two years have been from the license and collaboration agreements with AstraZeneca, Servier, Seagen, Genentech and Boston Pharmaceuticals.

The revenues from AstraZeneca, Servier, Seagen, Genentech and Boston Pharmaceuticals have been comprised primarily of upfront payments, research and development services and milestone payments. For additional information about our revenue recognition policy, see "Note 2-Summary of Significant Accounting Policies".

Research and Development Expenses

The process of researching and developing drugs for human use is lengthy, unpredictable, and subject to many risks. We expect to continue incurring substantial expenses for the next several years as we continue to develop our clinical and preclinical drug candidates and programs. We are unable, with any certainty, to estimate either the costs or the timelines in which those expenses will be incurred. Our current development plans focus on the following programs: our lead respiratory program, elarekibep, our proprietary respiratory programs, PRS-220 and PRS-400, and our partnered IO programs, including PRS-344/S095012. These programs consume a large proportion of our current, as well as projected, resources.

Our research and development costs include costs that are directly attributable to the creation of certain of our Anticalin drug candidates and are comprised of:





  • internal recurring costs, such as personnel-related costs (salaries, employee
    benefits, equity compensation and other costs), materials and supplies,
    facilities and maintenance costs attributable to research and development
    functions; and


  • fees paid to external parties who provide us with contract services, such as
    preclinical testing, manufacturing and related testing and clinical trial
    activities.



General and Administrative Expenses

General and administrative expenses consist primarily of salaries, employee benefits, equity compensation, and other personnel-related costs associated with executive, administrative and other support staff. Other significant general and administrative expenses include the costs associated with professional fees for accounting, auditing, insurance costs, consulting and legal services, along with facility and maintenance costs attributable to general and administrative functions.

Revenues


The following table provides a comparison of revenues for the years ended December 31, 2022 and 2021 (in thousands):





                          Year Ended December 31,
                            2022             2021         Increase/(Decrease)
Customer revenue        $     25,469       $  27,940     $              (2,471 )
Collaboration revenue            433           3,478                    (3,045 )
Total Revenue           $     25,902       $  31,418                    (5,516 )




  • The $2.5 million decrease in customer revenue for the year ended December 31,
    2022 compared to the year ended December 31, 2021 is driven by the following:


  • Current year revenue recorded due to the discontinuation of two early-stage
    programs under the AstraZeneca collaboration (approximately $9.2 million),
    completion of the performance obligation related to the material right for
    PRS-352 (approximately $4.9 million), milestone revenue recorded under the
    Seagen collaboration ($5.0 million) and completion of the performance
    obligation related to the expiration of the target swap for the second program
    under the Seagen collaboration (approximately $1.5 million) as well as program
    progress on the Seagen and Genentech collaborations.


  • Prior year revenue was slightly higher and primarily consisted of a phase 2a
    milestone ($13.0 million) recognized for elarekibep under the AstraZeneca
    collaboration along with higher reimbursable costs incurred on this program,
    revenue recognized under the Boston Pharmaceuticals collaboration ($5.7
    million) and higher reimbursable costs for phase 1 preparation activities due
    from  Servier. .


  • Collaboration revenue decreased by $3.0 million in the year ended December 31,
    2022 compared to the year ended December 31, 2021. The decrease relates to an
    updated estimate of project completion for PRS-344/S095012 under the Servier
    collaboration, leading to lower revenue recognized in the current period along
    with increased activities managed by Servier for the phase 1 study which
    offset our revenue generating activities.

Research and Development Expenses

The following table provides a comparison of the research and development expenses for the years ended December 31, 2022 and 2021 (in thousands):





                         Year Ended December 31,
                           2022             2021         Increase/(Decrease)
Respiratory            $     12,845       $  17,158     $              (4,313 )
Immuno-oncology              13,743          23,210                    (9,467 )
Other R&D activities         26,394          26,288                       106
Total                  $     52,982       $  66,656                   (13,674 )




  • The $9.5 million decrease in our immuno-oncology program spending
    period-over-period is due primarily to a decrease in overall costs for
    cinrebafusp alfa as the program was stopped during 2022, decreased
    manufacturing costs for PRS-344/S095012, and lower license fees given
    transactions that occurred in 2021, partially offset by higher clinical costs
    for PRS-344/S095012 and slightly higher pre-clinical costs for discovery stage
    programs.


  • The $4.3 million decrease for our respiratory program spending
    period-over-period is due to lower program costs for elarekibep as there was
    limited phase 1 clinical activities to complete in 2022 along with some phase
    2 manufacturing costs both of which were fully reimbursed by AstraZeneca,
    lower manufacturing costs for PRS-220, and lower license fees given amendments
    to the AstraZeneca collaboration that occurred in 2021, all partially offset
    by higher clinical costs for PRS-220 and higher pre-clinical and consumable
    costs for PRS-400.


  • The $0.1 million increase in other research and development activities
    expenses is due primarily to higher personnel costs due to higher average
    headcount along with an increase in travel expenses, both partially offset by
    lower overall license fees, lower external consulting expenses, and lower
    general lab supply costs.



General and Administrative Expenses

General and administrative expenses were $16.4 million for the year ended December 31, 2022 as compared to $16.6 million for the year ended December 31, 2021. The slight period-over-period decrease was driven primarily by lower personnel costs, facilities and IT costs, and audit and tax costs, partially offset by higher amortization of deferred costs related to costs to obtain a contract , business development and travel costs.





Other income (expense), net


Our other income was $10.2 million for the year ended December 31, 2022 as compared to a other expense of $6.1 million for the year ended December 31, 2021. This period over period increase was primarily due to a full year of grant income recorded for PRS-220 in the current period as compared to a partial year in the same period in the prior year, interest income on investments in the current year as well as a strengthening US dollar for the majority of the current year, partially offset by higher foreign exchange realized losses in the current year as compared to the same period in the prior year.

Liquidity and Capital Resources

We are subject to risks common to companies in the biotechnology industry, including but not limited to, the need for additional capital, risks of failure of preclinical studies and clinical trials, the need to obtain marketing approval and reimbursement for any drug product candidate that we may identify and develop, the need to successfully commercialize and gain market acceptance of our product candidates, dependence on key personnel, protection of proprietary technology, compliance with government regulations, development of technological innovations by competitors, reliance on third-party manufacturers and the ability to transition from pilot-scale production to large-scale manufacturing of products.

Through December 31, 2022, we have funded our operations with $521.5 million of cash that has been obtained from the following main sources: $283.2 million from sales of equity; $217.7 million in total upfront and milestone payments received under license and collaboration agreements and $20.6 million from government grants.

As of December 31, 2022, we had a total of $59.2 million in cash, cash equivalents and investments. We have incurred losses in every period since inception including the years ended December 31, 2022 and 2021, respectively, and have a total accumulated deficit of $290.4 million as of December 31, 2022. Net losses and negative cash flows have had, and will continue to have, an adverse effect on our stockholders' equity and working capital. We expect to continue to incur operating losses for at least the next several years.

                                              Year Ended December 31,
                                                2022              2021

Net cash used in operating activities $ (59,932 ) $ (7,660 ) Net cash used in investing activities

             (21,236 )         (949 )
Net cash provided by financing activities           7,214         59,127




Net cash used in operating activities for the year ended December 31, 2022 and 2021 was $59.9 million and $7.7 million, respectively. Cash used in the current period is impacted by lower deferred revenue, primarily driven by higher revenue recognized for AstraZeneca, Servier and Seagen out of the deferred balance, lower accounts payable and accrued expenses and higher accounts receivable and prepaid expenses. This compares to the impact of higher deferred revenue, primarily driven by the new collaboration agreements with Boston Pharmaceuticals and Genentech and higher accounts payable and accrued expenses, offset partially by higher accounts receivables and prepaid expenses in the prior period.

The change in net cash used in investing activities for the year ended December 31, 2022 compared to net cash used in investing activities in 2021 is solely attributable to the impact of net investments changes (purchase of investments as a result of rising interest rates in 2022) for which there is no activity in the comparable prior year period.

Financing activities for the year ended December 31, 2022 and 2021 provided cash of $7.2 million and $59.1 million, respectively. The decrease in 2022 compared to 2021 is driven by equity investments from both Seagen and AstraZeneca, higher sales activity under our ATM programs and higher proceeds received from warrant and option exercises in the prior period compared to more limited ATM sales activity and warrant and option exercises in 2022 given the overall lower stock price.

In August 2019, we entered into a sales agreement pursuant to which we may offer and sell shares of our common stock, from time to time, up to an aggregate gross sales proceeds of $50.0 million through an "at the market offering" program, or the 2019 ATM Program, under a shelf registration statement on Form S-3 (File No. 333-226725). In August 2021, the 2019 ATM Program expired. In August 2021, we established a second ATM offering program, or the 2021 ATM Program, under the existing sales agreement with Jefferies LLC, pursuant to which the Company may offer and sell shares of its common stock, from time to time, up to an aggregate amount of gross sales proceeds of $50.0 million. In November 2022, the sales agreement was amended to provide for an increase in the aggregate offering amount, such that under the 2021 ATM Program, as amended, the Company may offer and sell shares of its common stock, from time to time, up to an aggregate amount of gross sales proceeds of $75.0 million. The 2021 ATM Program, as amended, is offered under a shelf registration statement on Form S-3 (File No. 333-258497) that was filed with and declared effective by the SEC in August 2021. For the year ended December 31, 2022, we sold 2.1 million shares for gross proceeds of $7.2 million under the ATM program at an average stock price of $3.46. For the year ended December 31, 2021, we sold 8.2 million shares for gross proceeds of $39.7 million under both ATM programs at an average stock price of $4.85.

Our future success is dependent on our ability to identify and develop our product candidates, expand our corporate infrastructure and ultimately upon our ability to attain profitable operations. We have devoted substantially all of our financial resources and efforts to research and development and general and administrative expenses to support such research and development. We have several research and development programs underway in varying stages of development and we expect that these programs will continue to require increasing amounts of cash for development, conducting clinical trials, and testing and manufacturing of product material. Cash necessary to fund operations will increase significantly over the next several years as we continue to conduct these activities necessary to pursue governmental regulatory approval of clinical-stage programs and other product candidates.

Any requirements for additional capital will depend on many factors, including the following:





  • the scope, rate of progress, results and cost of our clinical studies,
    preclinical testing and other related activities;


  • the cost of manufacturing clinical supplies, and establishing commercial
    supplies, of our drug candidates and any products that we may develop;


  • the number and characteristics of drug candidates that we pursue;


  • the cost, timing and outcomes of regulatory approvals;




                                       99

  • the cost and timing of establishing sales, marketing and distribution
    capabilities;


  • the terms and timing of any collaborative, licensing and other arrangements
    that we may establish;


  • the timing, receipt and amount of sales, profit sharing or royalties, if any,
    from our potential products;


  • the cost of preparing, filing, prosecuting, defending and enforcing any patent
    claims and other intellectual property rights;


  • the extent to which we acquire or invest in businesses, products or
    technologies, although we currently have no commitments or agreements relating
    to any of these types of transactions; and


  • the effects of the COVID-19 pandemic and the cost and timing of actions taken
    to contain it.



In addition, any unfavorable development or delay in the progress of our core clinical-stage programs, including elarekibep, could have a material adverse impact on our ability to raise additional capital. We would need to raise additional capital over the next year to continue our current level of research and development activities across all of our active programs, as well as to maintain the general and administrative functions to support such activities. Without access to additional capital or management making decisions to reduce spending, these conditions raise substantial doubt about our ability to continue as a going concern.

We plan to raise additional capital to fulfill our operating and capital requirements through public or private equity financings, utilization of our current "at the market offering" program, or ATM Program, strategic collaborations, licensing arrangements, government grants and/or the achievement of milestones under our collaborative agreements. The funding requirements of our operating plans, however, are based on estimates that are subject to risks and uncertainties and may change as a result of many factors currently unknown. Although management continues to pursue these funding plans, there is no assurance that we will be successful in obtaining sufficient funding on terms acceptable to us to fund continuing operations, if at all. Until such time that we can generate substantial product revenues, if ever, we expect to finance our cash needs through a combination of equity offerings, debt financings, strategic partnerships, licensing arrangements and government grants. The terms of any future financing may adversely affect the holdings or the rights of our existing stockholders.

If we are unable to obtain additional funding on acceptable terms when needed, we will defer or limit a substantial portion of our research, development and clinical projects, reduce discretionary expenditures and other fixed or variable personnel costs to alleviate the substantial doubt as to our ability to continue as a going concern. Our budget and operating plan for 2023, approved by the Board, does not include such discretionary costs, and management is prepared to gate future investments on PRS-220 and PRS-400, including certain Phase 2-readiness activities for PRS-220 and IND-enabling activities for PRS-400, in the interest of achieving our top priority, namely, obtaining data from the elarekibep Phase 2a study in asthma. On the basis of our approved budget and actions within management's control, we believe that our currently available funds will be sufficient to fund our remaining limited operations through at least the next 12 months from the issuance of this Annual Report on Form 10-K. Our belief with respect to our ability to fund operations is based on estimates that are subject to risks and uncertainties.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, as defined under applicable SEC rules.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP. The preparation of these financial statements requires management to make estimates and judgments that affect reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses for the periods presented. Management makes estimates and exercises judgment in revenue recognition, accrued and prepaid clinical trial expenses, share-based payments and income taxes. Judgments must also be made about the disclosure of contingent liabilities, and these estimates and assumptions form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from those estimates and under different assumptions or conditions.

While our significant accounting policies are more fully described in the notes to our consolidated financial statements, we have identified the following accounting policies that we believe require application of management's most subjective judgments, often requiring the need to make estimates about the effect of matters that are inherently uncertain and may change in subsequent periods. Our actual results could differ from these estimates and such differences could be material.

Revenue Recognition


Pieris has entered into several licensing agreements with collaboration partners for the development of Anticalin therapeutics against a variety of targets. The terms of these agreements provide for the transfer of multiple goods or services which may include: (i) licenses, or options to obtain licenses, to Pieris' Anticalin technology and/or specific programs and (ii) research and development activities to be performed on behalf of or with a collaborative partner. Payments to Pieris under these agreements may include upfront fees (which include license and option fees), payments for research and development activities, payments based upon the achievement of certain milestones, and royalties on product sales. There are no performance, cancellation, termination or refund provisions in any of the arrangements that could result in material financial consequences to Pieris.

The Company accounts for revenue recognition pursuant to FASB ASC Topic 606, Revenue Recognition, or ASC 606. The standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services.





Collaborative Arrangements



We consider the nature and contractual terms of an arrangement and assess whether the arrangement involves a joint operating activity pursuant to which we are an active participant and are exposed to significant risks and rewards with respect to the arrangement. If we are an active participant and are exposed to the significant risks and rewards with respect to the arrangement, we account for these arrangements pursuant to ASC 808, Collaborative Arrangements, or ASC 808, and apply a systematic and rational approach to recognize revenue. We classify payments received as revenue and payments made as a reduction of revenue in the period in which they are earned.

Revenue from Contracts with Customers

In accordance with ASC 606, revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration to which we expect to be entitled in exchange for these goods and services. To achieve this core principle, we apply the following five steps: 1) identify the customer contract; 2) identify the contract's performance obligations; 3) determine the transaction price; 4) allocate the transaction price to the performance obligations; and 5) recognize revenue when or as a performance obligation is satisfied.

We evaluate all promised goods and services within a customer contract and determines which of such goods and services are separate performance obligations. This evaluation includes an assessment of whether the good or service is capable of being distinct and whether the good or service is separable from other promises in the contract. In assessing whether promised goods or services are distinct, we consider factors such as the stage of development of the underlying intellectual property and the capabilities of the customer to develop the intellectual property on their own or whether the required expertise is readily available.

Licensing arrangements are analyzed to determine whether the promised goods or services, which often include licenses, research and development services and governance committee services, are distinct or whether they must be accounted for as part of a combined performance obligation. If the license is considered not to be distinct, the license would then be combined with other promised goods or services as a combined performance obligation. If we are involved in a governance committee, we assess whether our involvement constitutes a separate performance obligation. When governance committee services are determined to be separate performance obligations, we determine the fair value to be allocated to this promised service.

Certain contracts contain optional and additional items, which are considered marketing offers and are accounted for as separate contracts with the customer if such option is elected by the customer, unless the option provides a material right which would not be provided without entering into the contract. An option that is considered a material right is accounted for as a separate performance obligation.

The transaction price is determined based on the consideration to which we will be entitled in exchange for transferring goods and services to the customer. A contract may contain variable consideration, including potential payments for both milestone and research and development services. For certain potential milestone payments, we estimate the amount of variable consideration by using the most likely amount method. In making this assessment, we evaluate factors such as the clinical, regulatory, commercial and other risks that must be overcome to achieve the milestone. Each reporting period we re-evaluate the probability of achievement of such variable consideration and any related constraints. We will include variable consideration, without constraint, in the transaction price to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. For potential research and development service payments, we estimate the amount of variable consideration by using the expected value method, including any approved budget updates arising from additional research or development services.

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price among the performance obligations on a relative standalone selling price basis unless a portion of the transaction price is variable and meets the criteria to be allocated entirely to a performance obligation or to a distinct good or service that forms part of a single performance obligation.



                                      101

Table of Contents

We allocate the transaction price based on the estimated standalone selling price of the underlying performance obligations or in the case of certain variable consideration to one or more performance obligations. We must develop assumptions that require judgment to determine the stand-alone selling price for each performance obligation identified in the contract. We utilize key assumptions to determine the stand-alone selling price, which may include other comparable transactions, pricing considered in negotiating the transaction and the estimated costs to complete the respective performance obligation. Certain variable consideration is allocated specifically to one or more performance obligations in a contract when the terms of the variable consideration relate to the satisfaction of the performance obligation and the resulting amounts allocated to each performance obligation are consistent with the amount we would expect to receive for each performance obligation.

When a performance obligation is satisfied, revenue is recognized for the amount of the transaction price, excluding estimates of variable consideration that are constrained, that is allocated to that performance obligation on a relative standalone selling price basis. Significant management judgment is required in determining the level of effort required under an arrangement and the period over which we are expected to complete its performance obligations under an arrangement.

For performance obligations consisting of licenses and other promises, we utilize judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non- refundable, up-front fees. We evaluate the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition. If the license to our intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, we will recognize revenue from non-refundable, up-front fees allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license.





Milestones and Royalties


We aggregate milestones into four categories: (i) research milestones, (ii) development milestones, (iii) commercial milestones, and (iv) sales milestones. Research milestones are typically achieved upon reaching certain success criteria as defined in each agreement related to developing an Anticalin protein against the specified target. Development milestones are typically reached when a compound reaches a defined phase of clinical research or passes such phase or upon gaining regulatory approvals. Commercial milestones are typically achieved when an approved pharmaceutical product reaches the status for commercial sale, including regulatory approval. Sales milestones are certain defined levels of net sales by the licensee, such as when a product first achieves global sales or annual sales of a specified amount.

There is uncertainty that the events to obtain the research and development milestones will be achieved given the nature of clinical development and the stage of our technology. We have thus determined that all research and development milestones will be constrained until it is deemed probable that a significant revenue reversal will not occur. For revenues from research and development milestones, payments will be recognized consistent with the recognition pattern of the performance obligation to which they relate.

For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and for which the license is deemed to be the predominant item to which the royalties relate, we recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). Commercial milestones and sales royalties are determined by sales or usage-based thresholds and will be accounted for under the royalty recognition constraint as constrained variable consideration.





Contract Balances


We recognize a contract asset when we transfer goods or services to a customer before the customer pays consideration or before payment is due, excluding any amounts presented as a receivable (i.e., accounts receivable). A contract asset is an entity's right to consideration in exchange for goods or services that the entity has transferred to a customer. The contract liabilities (i.e., deferred revenue) primarily relate to contracts where we have received payment but has not yet satisfied the related performance obligations.





Contingencies


Accruals are recorded for loss contingencies when it is probable that a liability has been incurred and the amount of the related loss can be reasonably estimated. We evaluate, on a quarterly basis, developments in legal proceedings and other matters that could cause an increase or decrease in the amount of the liability that has been accrued previously. Considering facts known at the time of the assessment, we determine whether potential losses are considered reasonably possible or probable and whether they are estimable. Based upon this assessment, we carry out an evaluation of disclosure requirements and consider possible accruals in the financial statements.

Research and Development Expense

Research and development costs are charged to expense as incurred in performing research and development activities. Research and development expenses are comprised of costs incurred in performing research and development activities, including salaries and benefits, facilities costs, pre-clinical and clinical costs, contract services, consulting, depreciation and amortization expense, and other related costs. Costs associated with acquired technology, in the form of upfront fees or milestone payments, are charged to research and development expense as incurred.





Income Taxes


Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating losses and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted statutory tax rates expected to apply to taxable income in the jurisdictions and years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

We evaluate the realizability of our net deferred tax assets, including considering the level of historical operating results and projections of taxable income for the future. We record a full valuation allowance to reduce our net deferred tax assets when it is determined that it is more likely than not that our net deferred tax assets will not be realized.

We recognize, measure, present and disclose in our financial statements any uncertain tax positions that we have taken or expect to take on a tax return. We operate in multiple jurisdictions, both within and outside the United States, and may be subject to audits from various tax authorities. Management's judgment is required in determining our provision for income taxes, our deferred tax assets and liabilities, liabilities for uncertain tax positions, and any valuation allowance recorded against our net deferred tax assets. We will monitor the extent to which our deferred tax assets may be realized and adjust the valuation allowance accordingly.

Our policy is to classify interest and penalties related to unrecognized tax benefits as income tax expense

Recently Issued Accounting Pronouncements

We review new accounting standards to determine the expected financial impact, if any, that the adoption of each standard will have. For the recently issued accounting standards that we believe may have an impact on our consolidated financial statements, see "Note 2-Summary of Significant Accounting Policies" in our consolidated financial statements.

Smaller Reporting Company Status

Currently, we qualify as a smaller reporting company.

As a smaller reporting company, we are eligible and have taken advantage of certain exemptions from various reporting requirements that are not available to public reporting companies that do not qualify for this classification, including, but not limited to:





  • An opportunity for reduced disclosure obligations regarding executive
    compensation in our periodic and annual reports, including without limitation
    exemption from the requirement to provide a compensation discussion and
    analysis describing compensation practices and procedures,


  • An opportunity for reduced financial statement disclosure in registration
    statements and in annual reports on Form 10-K, which only requires two years
    of audited financial statements rather than the three years of audited
    financial statements that are required for other public companies,


  • An opportunity for reduced audit and other compliance expenses as we are not
    subject to the requirement to obtain an auditor's report on internal control
    over financial reporting under Section 404(b) of the Sarbanes-Oxley Act of
    2002, and


  • An opportunity to utilize the non-accelerated filer time-line requirements
    beginning with our annual report for the year ending December 31, 2020 and
    quarterly filings thereafter.



For as long as we continue to be a smaller reporting company, we expect that we will take advantage of both the reduced internal control audit requirements and the disclosure obligations available to us as a result of this classification.
