The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our financial statements and related notes thereto included elsewhere in this Quarterly Report on Form 10-Q ("Quarterly Report") and our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020 (the "Annual Report") filed with the Securities and Exchange Commission (the "SEC") on March 23, 2021. Some of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report, including information with respect to our plans and strategy for our business, includes forward looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the "Risk Factors" section in our Annual Report and in this Quarterly Report, our actual results could differ materially from the results described in or implied by, the forward-looking statements contained in the following discussion and analysis.

OVERVIEW

We are a pharmaceutical company focused on developing and commercializing products that have the potential to optimize the delivery of infused therapies, advance patient care and reduce healthcare costs. Our strategy is designed to enable the subcutaneous administration of therapies that have previously been limited to intravenous, or IV, delivery. By moving delivery away from the high-cost healthcare settings typically required for IV administration, we believe our technology has the potential to reduce overall healthcare costs and advances the quality and convenience of care. Our lead product candidate, FUROSCIX, consists of our novel formulation of furosemide delivered via an on-body infusor and is under development for treatment of congestion in patients with heart failure who display reduced responsiveness to oral diuretics and do not require hospitalization.

We resubmitted our new drug application, or NDA, for FUROSCIX, with the U.S. Food and Drug Administration, or FDA, on June 30, 2020. The resubmission was a response to a Complete Response Letter, or CRL, from the FDA with respect to our NDA submitted in August 2017, which indicated that, among other things, certain device modifications to our infusor were required. Based on our interactions with the FDA, which required device modifications necessary to advance FUROSCIX using its then current technology, we decided to transition to our next generation device. The resubmission incorporated our next generation device which is being developed through a partnership with West Pharmaceutical Services, Inc., or West, using its proprietary on-body infusor.

On July 23, 2020, the FDA accepted the resubmission of our NDA and we were given a Prescription Drug User Fee Act, or PDUFA, target action date of December 30, 2020; however, on December 3, 2020, we received a CRL from the FDA, in which, among other things, the FDA raised questions related to testing, labeling and features of the combination product unrelated to the drug constituent. The FDA also indicated that they needed to conduct pre-approval inspections at three of our third-party manufacturing facilities. No clinical deficiencies were noted. On January 28, 2021, we had a Type A meeting with the FDA to discuss the issues described in the CRL and steps required for the resubmission of the NDA for FUROSCIX. On June 2, 2021, we had a Type C meeting with the FDA regarding the requirements for resubmission of the FUROSCIX NDA. Based on guidance we received during the meeting and subsequently contained within the meeting minutes, we are conducting the required bench testing for the West proprietary on-body infusor. The FDA has not requested modifications to the device and all testing to date on devices manufactured on the planned commercial line has been successful, however, due to COVID-19 related global supply chain logistics we plan to resubmit our NDA in the first quarter of 2022. If the resubmission is approved, we still anticipate a commercial launch in the fourth quarter of 2022.

In May 2021, we completed enrollment in FREEDOM-HF, a prospective clinical trial evaluating overall and heart failure-related costs for subjects treated with FUROSCIX outside the hospital for 30 days post-discharge from the emergency department compared to patients receiving intravenous furosemide in the hospital setting. Based on the results from a planned, prespecified interim analysis conducted to confirm the final sample size, and following input from statisticians, principal investigators, payer advisors and Health Economics and Outcomes Research (HEOR) experts, enrollment was closed on May 17, 2021, prior to the enrollment target of 34 patients. This decision was made due to the statistically significant reduction observed in 30-day heart failure-related costs in patients who received FUROSCIX in the interim analysis. The final analysis included 24 subjects treated with FUROSCIX and 66 matched comparators based on seven variables associated with hospitalization. On July 13, 2021, we announced top-line results from FREEDOM-HF, demonstrating that average 30-day heart failure-related costs were reduced by $17,753 per study subject in the FUROSCIX arm compared to historically matched comparators (p < 0.0001). In September, we announced additional results from FREEDOM-HF, demonstrating that average 30-day total healthcare costs were reduced by $30,568 per study subject in the FUROSCIX arm compared to historically matched comparators (p < 0.0001). Since the price for FUROSCIX has not been established, the difference in costs does not include the cost of FUROSCIX. These results support our hypothesis that treating heart failure patients presenting to the emergency department with worsening congestion with FUROSCIX outside of the hospital setting has the potential to dramatically reduce the significant costs associated with hospital admissions and readmissions.

We conducted an analysis of additional secondary endpoints in FREEDOM-HF which provided additional insights into the clinical effectiveness of FUROSCIX. In this analysis, it was determined that patients who received FUROSCIX had a median reduction of



                                       15

--------------------------------------------------------------------------------

heart failure peptide biomarkers from study entry to first visit, and to last visit, of 42.3% and 28%, respectively (p < 0.01). In addition, patients who received FUROSCIX had a 12.8-point improvement in the Kansas City Cardiomyopathy Questionnaire (KCCQ-12) Summary Score 30 days after study entry.

We continued enrollment in AT HOME-HF PILOT, a multicenter, randomized, open label, controlled study in heart failure patients with worsening signs and symptoms of congestion requiring augmentation in diuretic therapy outside of an acute care setting. The objective of this pilot study is to evaluate the effectiveness and safety of FUROSCIX versus continued medical therapy to inform a larger, pivotal clinical trial. We anticipate completing enrollment in the AT HOME-HF PILOT study in the first half of 2022.

We have funded our operations from inception through September 30, 2021 primarily through the sale of shares of our common stock and, prior to that, through the private placement of our preferred stock and the incurrence of debt. We do not have any products approved for sale and have not generated any revenue from product sales.

As of September 30, 2021, we had an accumulated deficit of $182.4 million. We expect to continue to incur net losses for the foreseeable future as we develop the infrastructure to commercialize our products, if approved, in the United States, including building our sales and marketing organization, continuing research and development efforts, engaging in scale-up manufacturing and seeking regulatory approval for new product candidates and enhancements. We will need additional funding to pay expenses related to our operating activities, including selling, general and administrative expenses and research and development expenses. Adequate funding may not be available to us on acceptable terms, or at all. Our failure to obtain sufficient funds on acceptable terms when needed could have a material adverse effect on our business, results of operations or financial condition.

IMPACT OF COVID-19

A new strain of novel coronavirus which causes a severe respiratory disease ("COVID-19") was identified in 2019, and subsequently declared a pandemic by the World Health Organization, affecting the populations of the United States as well as the rest of the world. In response to the pandemic, we transitioned our workforce to work from home in March 2020. In July 2020, we opened our offices for limited access to employees integrating all recommendations for workplace safety, including appropriate protocols to ensure social-distancing. The health of our employees remains a top priority and we are continuing to monitor the impact of COVID-19 including the pace of vaccinations and the emergence of new and more contagious strains of the virus and government regulations.

To date, the third parties that perform our manufacturing, assembly, packaging and testing of our products have experienced delays relating to supply chain logistics but have remained operational. The extent of the impact of the evolving COVID-19 pandemic on the timing of our ability to resubmit the FUROSCIX NDA, the FDA's subsequent review of the FUROSCIX NDA or possible delays in enrolling patients to our upcoming or recently initiated trials and our operational and financial performance will depend on future developments, including the duration, severity and spread of the pandemic, related restrictions on travel and transportation, the impact of new strains of the virus, the effectiveness and availability of vaccines and other actions that may be taken by governmental authorities, including the ability of the FDA to inspect facilities required for approval of our NDA, the impact to the business of our suppliers, service providers or customers, and other items identified under "Risk Factors" in our Annual Report on Form 10-K, all of which are uncertain and cannot be predicted. An extended period of global supply chain and economic disruption may continue to impact us and could materially affect our business, results of operations, access to sources of liquidity and financial condition.

COMPONENTS OF OUR RESULTS OF OPERATIONS

Research and Development Expenses

Research and development, or R&D, expenses consist of the cost of engineering, clinical trials, regulatory and medical affairs and quality assurance associated with developing our proprietary technology and product candidates. R&D expenses consist primarily of:



?
employee-related expenses, including salaries, benefits, travel expense and
stock-based compensation expense;
?
cost of outside consultants who assist with technology development, regulatory
affairs, clinical trials and medical affairs, and quality assurance;
?
cost of clinical trial activities performed by third parties;
?
cost of pre-approval pharmaceutical batch manufacturing; and
?
cost of facilities and supplies used for internal research and development and
clinical activities.

We expense R&D costs as incurred. Given the emphasis to date on our lead product candidate FUROSCIX, our R&D expenses have not been allocated on a program-specific basis. In the future, we expect R&D expenses to increase in absolute dollars as we



                                       16

--------------------------------------------------------------------------------

continue to develop new products and enhance existing products and technologies. We anticipate that our expenses will increase significantly as we:



?
pursue regulatory approval of FUROSCIX incorporating the West proprietary
on-body infusor;
?
continue to advance our pipeline programs beyond FUROSCIX;
?
continue our current research and development activity;
?
seek to identify additional research programs and additional product candidates;
?
initiate preclinical testing and clinical trials for any product candidates we
identify and develop, maintain, expand and protect our intellectual property
portfolio; and
?
hire additional research, clinical and scientific personnel.

General and Administrative Expenses

General and administrative, or G&A, expenses consist of employee-related expenses, including salaries, benefits, travel expense and stock-based compensation expense for personnel in executive, finance, commercial, human resources, facility operations and administrative functions. Other G&A expenses include pre-approval promotional activities, marketing, conferences and trade shows, professional services fees, including legal, audit and tax fees, insurance costs, general corporate expenses and allocated facilities-related expenses.

If we receive FDA approval for FUROSCIX incorporating West's proprietary on-body infusor, we anticipate that our G&A expenses will increase as we continue to build our corporate and commercial infrastructure to support the development and commercial launch of FUROSCIX in the United States.

LIQUIDITY AND CAPITAL RESOURCES

Overview

We have funded our operations from inception through September 30, 2021 primarily through the sale of shares of our common stock and, prior to that, through the private placement of our preferred stock and the incurrence of debt. As of September 30, 2021, we had received net cash proceeds of $92.7 million from our initial public offering, $56.7 million from sales of our preferred stock, $18.8 million from borrowings under our term loan, $13.5 million from sales of convertible notes, $50.2 million from our



                                       18

--------------------------------------------------------------------------------

public offering in 2020 and $14.4 million from the sale of common stock in our 2019 at-the-market offering. As of September 30, 2021, we had cash, cash equivalents and restricted cash of $79.5 million and short-term investments of $5.5 million.

On March 23, 2021, we entered into the 2021 ATM Agreement with Cowen to sell shares of our common stock, from time to time, with aggregate gross sales proceeds of up to $50.0 million, through an at-the-market equity offering program under which Cowen will act as our sales agent. As of September 30, 2021, we had received no proceeds from the sale of shares of common stock pursuant to the 2021 ATM Agreement.

We expect to incur substantial additional expenditures in the near future to support our ongoing activities and our plans to obtain regulatory approval for FUROSCIX incorporating West's proprietary on-body infusor. We believe our existing unrestricted cash is sufficient to fund our operations through at least the next 12 months from the date of this quarterly report. We expect our costs and expenses to increase in the future as we prepare for and, if approved, commence U.S. commercialization of FUROSCIX, including the development of a direct sales force, and as we continue to make substantial expenditures on research and development, including to increase our manufacturing capacity and for conducting clinical trials of our product candidates. Additionally, we will incur additional costs as a result of operating as a public company. Our future capital requirements will depend on many factors, including:



?

the time and expense required to resubmit the NDA for FUROSCIX;





?

the potential FDA approval of FUROSCIX;





?

the costs and expenses of establishing our U.S. sales and marketing infrastructure;





?

the degree of success we experience in commercializing FUROSCIX, if approved;





?

the revenue generated by sales of FUROSCIX, if approved, and other products that may be approved;





?

the pricing and reimbursement of FUROSCIX, if approved, and of other product candidates that may be approved;





?

the costs, timing and outcomes of clinical trials and regulatory reviews associated with our product candidates;





?

the emergence of competing or complementary technological developments;





?

the extent to which FUROSCIX, if approved, is adopted by the healthcare community;





?

the number and types of future products we develop and commercialize;





?

the costs of preparing, filing and prosecuting patent applications and maintaining, enforcing and defending intellectual property-related claims;





?

the impact of COVID-19 on our operations; and





?

the extent and scope of our general and administrative expenses.

Additional financing may not be available on a timely basis on terms acceptable to us, or at all. We may raise funds in equity, royalty-based or debt financings or enter into additional credit facilities in order to access funds for our capital needs. If we raise additional funds through further issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution in their percentage ownership of our company, and any new equity securities we issue could have rights, preferences and privileges senior to those of holders of our common stock. If we raise additional funds through royalty-based financing arrangements, we will likely agree to relinquish rights to potentially valuable future revenue streams and may agree to covenants that restrict our operations or strategic flexibility. Any debt financing obtained by us in the future would cause us to incur additional debt service expenses and could include restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and pursue business opportunities. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, we may terminate or delay the development of one or more of our products, delay clinical trials necessary to market our products, or delay establishment or expansion of sales and marketing capabilities or other activities necessary to commercialize our products.

Net Cash Used in Operating Activities

During the nine months ended September 30, 2021, net cash used in operating activities was $20.1 million, consisting primarily of a net loss of $20.7 million and an increase in net operating assets of $1.9 million. This was offset by non-cash charges of $2.6 million, which primarily consisted of depreciation, amortization related to our right of use leased assets, stock-based compensation expense, non-cash interest expense related to amortization of debt discount associated with the 2019 Loan Agreement and accretion of discount on investments. The increase in net operating assets is related to accrued expenses for employee-related and device development costs.

During the nine months ended September 30, 2020, net cash used in operating activities was $18.5 million, consisting primarily of a net loss of $24.4 million. This was offset by non-cash charges of $2.6 million and an increase in net operating liabilities of $3.3 million. The non-cash charges primarily consisted of depreciation, amortization related to our right of use leased assets, stock-based compensation expense, non-cash interest expense related to amortization of debt discount associated with the 2019 Loan Agreement, accretion of discount on investments and the fair value adjustment to the derivative liability.

Net Cash (Used in) Provided by Investing Activities

During the nine months ended September 30, 2021, net cash provided by investing activities was $27.6 million, consisting primarily of maturities and purchases of short-term investments.

During the nine months ended September 30, 2020, net cash used in investing activities was $70.2 million, consisting of purchases of short-term investments.

Net Cash Provided by (Used in) Financing Activities

During the nine months ended September 30, 2021, net cash used in financing activities was $72,000, consisting primarily of tax obligations on the settlement of restricted stock units, offset by stock option exercises.

During the nine months ended September 30, 2020, net cash provided by financing activities was $60.3 million, consisting primarily of net proceeds of $50.2 million from the public offering, net proceeds of $10.4 million from the 2019 at-the-market offering and stock option exercises. The proceeds were offset by the $0.8 million Exit Fee associated with the 2019 Loan Agreement and tax obligations on the settlement of restricted stock units.

OFF-BALANCE SHEET ARRANGEMENTS

We currently have no off-balance sheet arrangements.

CONTRACTUAL OBLIGATIONS

There were no material changes in our commitments under contractual obligations, as disclosed in "Management's Discussion and Analysis of Financial Condition and Results of Operations" contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed with the SEC on March 23, 2021.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Management's discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP. The preparation of these financial statements requires us to make estimates and assumptions for the reported amounts of assets, liabilities, revenue, expenses and related disclosures. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions and any such differences may be material. Our critical accounting policies are more fully described under the heading "Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies and Estimates" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020, filed with the SEC on March 23, 2021.

JOBS ACT ACCOUNTING ELECTION

In April 2012, the Jumpstart Our Business Startups Act of 2012, or JOBS Act, was enacted. Section 107 of the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected not to avail ourselves of this extended transition period and, as a result, we adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies. This election is irrevocable.
