Overview



We are a clinical-stage specialty biopharmaceutical company focused on changing
the field of immunotherapy by developing a novel technology platform called
Viaskin. Our therapeutic approach is based on epicutaneous immunotherapy, or
EPITTM, our proprietary method of delivering biologically active compounds to
the immune system through intact skin using Viaskin. We have generated
significant data demonstrating that Viaskin's mechanism of action is novel and
differentiated, as it targets specific
antigen-presenting
immune cells in the skin, called Langerhans cells, that capture the antigen and
migrate to the lymph node in order to activate the immune system without passage
of the antigen into the bloodstream, minimizing systemic exposure in the body.
We are advancing this unique technology to treat patients, including infants and
children, suffering from food allergies, for whom safety is paramount, since the
introduction of the offending allergen into their bloodstream can cause severe
or
life-threatening
allergic reactions, such as anaphylactic shock. We believe Viaskin may offer
convenient, self-administered,
non-invasive
immunotherapy to patients.

Following receipt of a CRL from the FDA in connection with our BLA for Viaskin
Peanut, beginning in August 2020, we scaled down our other clinical programs and
pre-clinical spend to focus on Viaskin Peanut. We also initiated a global
restructuring plan in June 2020 to provide operational latitude to progress the
clinical development and regulatory review of Viaskin Peanut in the United
States and European Union.

In January 2021, we received written responses from the FDA to questions
provided in the Type A meeting request we submitted in October 2020 following
the CRL. The FDA agreed with our position that a modified Viaskin Peanut patch
should not be considered as a new product entity provided the occlusion chamber
of the current Viaskin Peanut patch and the peanut protein dose of 250 µg
(approximately 1/1,000 of one peanut) remains unchanged and performs in the same
way it has performed previously. In order to confirm the consistency of efficacy
data between the existing and a modified patch, FDA requested an assessment
comparing the uptake of allergen (peanut protein) between the patches in peanut
allergic children ages
4-11.
We named that assessment EQUAL, which stands for Equivalence in Uptake of
Allergen. The FDA also recommended conducting a
6-month,
well-controlled safety and adhesion trial to assess a modified Viaskin Peanut
patch in the intended patient population. We later named this clinical trial
STAMP, which stands for Safety, Tolerability, and Adhesion of Modified Patches.

Based on the January 2021 FDA feedback, we defined three parallel workstreams:

1. Identify a modified Viaskin patch (which we call mVP).

2. Generate the

6-month

safety and adhesion clinical data FDA requested via STAMP, which we expected

to be the longest component of the mVP clinical plan. We prioritized the

STAMP protocol submission so we could begin the clinical trial as soon as


    possible.



3. Demonstrate the equivalence in allergen uptake between the current and

modified patches in the intended patient population via EQUAL. The complexity

of EQUAL hinged on the lack of established clinical and regulatory criteria

to characterize allergen uptake via an epicutaneous patch. To support those

exchanges, we outlined our proposed approach to demonstrate allergen uptake

equivalence between the two patches, and allotted time to generate

informative data through two additional Phase I clinical trials in healthy


    adult volunteers:


a. PREQUAL, a Phase I trial with adult healthy volunteers to optimize the


            allergen sample collection methodologies and validate the assays we
            intend to use in EQUAL. The data collection phase of the trial is
            complete, and the data analysis phase is ongoing.



        b.  'EQUAL in adults,' a second Phase I trial with adult healthy
            volunteers to compare the allergen uptake of cVP and mVP.


In March 2021, we commenced CHAMP (Comparison of adHesion Among Modified
Patches), a Phase I trial in healthy adult volunteers to evaluate the adhesion
of five modified Viaskin Peanut patches. We completed CHAMP in the second
quarter of 2021. All modified Viaskin Peanut patches demonstrated better
adhesion performance as compared to the then-current Viaskin Peanut patch, and
based on the results of CHAMP, we then selected two modified patches that
performed best out of the five modified patches studied for further development.
We then selected the circular patch for further development, which is
approximately 50% larger in size relative to the current patch and circular in
shape.

In May 2021, we submitted our proposed STAMP protocol to the FDA, and on
October 14, 2021, we received an Advice/Information Request letter from the FDA.
In this letter, the FDA requested a stepwise approach to the modified Viaskin
patch development program and provided partial feedback on the STAMP protocol.
Specifically, the FDA requested that we conduct allergen uptake comparison
trials (i.e., 'EQUAL in Adults,' EQUAL), and submit the allergen uptake
comparison data for FDA review and feedback prior to starting the STAMP study.
The FDA's explanation was that the results from the allergen uptake trials might
affect the design of the STAMP study.

After careful review of the FDA's information requests, in December 2021, we
decided not to pursue the sequential approach to the development plans for
Viaskin Peanut as requested by the FDA in the October 2021 feedback. We
estimated that the FDA's newly proposed sequential approach would require at
least five rounds of exchanges that necessitate FDA alignment prior to
initiating STAMP, the
6-month
safety and adhesion study. As such, in December 2021, we announced we plan to
initiate a pivotal Phase 3 placebo-controlled efficacy trial for a modified
Viaskin Peanut patch (mVP) in children in the intended patient population. The
clinical trial will also include updates to the Instructions for Use (IFU). We
consider this approach the most straightforward to potentially demonstrate
effectiveness, safety, and improved in vivo adhesion of the modified Viaskin
Peanut system. The FDA has confirmed ("mVP") change in strategy is agreeable via
oral and written exchanges. The protocol for the new Phase 3 pivotal study of
the modified Viaskin Peanut (mVP) patch was completed at the end of February
2022 and was submitted to the FDA in April 2022. The Company has been granted a
Type C meeting by the FDA , which is expected to be held in the second quarter
of 2022, to align on the new Phase 3 study protocol.

Comparison of the three months ended March 31, 2022 to the three months ended March 31, 2021



Operating Income

We generated operating income of $2.5 million during the three months ended
March 31, 2022 compared to $2.9 million during the three months ended March 31,
2021, a decrease of 13.4%. This income was mainly generated from the French
research tax credit (
crédit d'impôt recherche)
, or CIR, and by revenue recognized under our collaboration agreement with
Nestlé Health Science.

                                   Three months Ended March

                                              31                    % change

Sales                                     -                  -
Other income                           2,546              2,941           (13 %)
Research tax credit                    1,569              1,807           (13 %)
Other operating (loss) income            976              1,133           (14 %)

Total operating income                 2,546              2,941           (13 %)



The decrease in operating income is primarily attributable to the decrease of
the CIR, as eligible expenses have declined in correlation with Research and
Development costs.

As of March 31, 2022, we recorded our collaboration contract income based on our
updated measurement of progress of the Phase II clinical trial conducted as part
of the collaboration and license agreement with Nestlé Health Science. The
accrual recorded in the amount of the difference between our current best
estimates of costs yet to be incurred and income yet to be recognized for the
completion of the Phase II clinical has been updated accordingly.

Research and development expenses decreased by $9.9 million for the three months
ended March 31, 2022, compared to the three months ended March 31, 2021,
primarily due to a decrease of $5.5 million in external clinical-related
expenses as main component of the work on clinical studies such as REALISE and
EPITOPE has been finalized during the year 2021. We have also continued to
practice financial diligence and implemented further cost containment
strategies.

Employee-related costs, excluding share-based payment expenses, decreased by
$1.6 million for the three months ended March 31, 2022, compared to the three
months ended March 31, 2021, due to the workforce reduction following full
implementation of the new organization.

The decrease in depreciation, amortization and other costs was primarily due to the reversal of loss at completion recorded on the Phase II clinical trial conducted as part of the Nestlé agreement.

Sales and Marketing expenses

The following table summarizes our sales and marketing expenses incurred during the three months ended March 31, 2022 and 2021:

Sales and marketing expenses decreased by $0.3 million for the three months ended March 31, 2022, compared to the three months ended March 31, 2021, primarily due to a decrease in employee-related costs, partially offset by depreciation and amortization costs.



Employee-related costs, excluding share-based payments expenses, decreased by
$0.3 million for the three months ended March 31, 2022, compared to the three
months ended March 31, 2021 due to the workforce reduction following full

General and administrative expenses decreased by $3.1 million for the three
months ended March 31, 2022, compared to the three months ended March 31, 2021,
primarily due to a decrease in employee-related costs and external professional
services as we continued to practice financial diligence and implemented further
cost containment strategies.

Employee-related costs, excluding share-based payments expenses, decreased by
$1.2 million for the three months ended March 31, 2022, compared to the three
months ended March 31, 2021 due to the workforce reduction following full
implementation of the new organization.

Financial income

Our financial income was $0.2 million for the three months ended March 31, 2022 and 2021. This item mainly includes foreign exchange income.

Net loss



Net loss was $16.7 million for the three months ended March 31, 2022, compared
to $29.4 million for the three months ended March 31, 2021. Net loss per share
(based on the weighted average number of shares outstanding over the period) was
$0.30 and $0.54 for three months ended March 31, 2022 and 2021, respectively.

Liquidity and Capital Resources

Financial Condition



On March 31, 2022, we had $74.1 million in cash and cash equivalents compared to
$77.3 million of cash and cash equivalents on December 31, 2021. We have
incurred operating losses and negative cash flows from operations since our
inception. Net cash used for operating activities was $1.5 and $36.2 million for
the three months ended March 31, 2022 and 2021, respectively. As of March 31,
2022, we recorded a net loss of $16.7 million.

Based on our current operations, as well as our plans and assumptions as revised
pursuant to our change of strategy announced in December 2021, we expect that
our balance of cash and cash equivalents of $74.1 million as of March 31, 2022
will be sufficient to fund our operations into the first quarter of 2023. As of
the date of the filing, our available cash is not projected to be sufficient to
support our operating plan for at least the next 12 months. As such, there is
substantial doubt regarding our ability to continue as a going concern.

We intend to seek additional capital as we prepare for the launch of Viaskin
Peanut, if approved, and continue other research and development efforts. We may
seek to finance our future cash needs through a combination of public or private
equity or debt financings, collaborations, license and development agreements
and other forms of non-dilutive financings. We cannot guarantee that we will be
able to obtain the necessary financing to meet our needs or to obtain funds at
attractive terms and conditions, including as a result of disruptions to the
global financial markets due to the ongoing COVID-19 pandemic. The ongoing
COVID-19 pandemic has already caused extreme volatility and disruptions in the
capital and credit markets. A severe or prolonged economic downturn could result
in a variety of risks to us, including reduced ability to raise additional
capital when needed or on acceptable terms, if at all.

If we are not successful in our financing objectives, we could have to scale
back our operations, notably by delaying or reducing the scope of our research
and development efforts or obtain financing through arrangements with
collaborators or others that may require us to relinquish rights to our product
candidates that we might otherwise seek to develop or commercialize
independently.

Our financial statements have been prepared on a going concern basis assuming
that we will be successful in our financing objectives. As such, no adjustments
have been made to the financial statements relating to the recoverability and
classification of the asset carrying amounts or classification of liabilities
that might be necessary should we not be able to continue as a going concern.

Sources and Material Cash Requirements



Based on our current operations, as well as our plans and assumptions as revised
pursuant to our change of strategy announced in December 2021, we expect that
our balance of cash and cash equivalents of $74.1 million as of March 31, 2022
will be sufficient to fund our operations into the first quarter of 2023.

                                       18

--------------------------------------------------------------------------------
We fund short-term cash requirements primarily from payments associated with
research tax credits (
Crédit d'Impôt Recherche
).

We have incurred net losses each year since our inception. Substantially all of
our net losses resulted from costs incurred in connection with our development
programs and from general and administrative expenses associated with our
operations. We have not incurred any bank debt.

As of the date of the filing, our available cash is not projected to be
sufficient to support our operating plan for at least the next 12 months. As
such, there is substantial doubt regarding our ability to continue as a going

actions under the contracts. The table does not include obligations under
agreements that we can cancel without a significant penalty.

Future events could cause actual payments to differ from these estimates.

Conditional advances



In 2014, BpiFrance Financement granted an interest-free Innovation loan to DBV
Technologies to help financing the pharmaceutical development of Viaskin
™
Milk. This amount was received in a single disbursement on November 27, 2014. In
2020, due to the
COVID-19
pandemic, Bpifrance postponed the repayments for a
6-month
period. Repayment will end during the third quarter of 2022.

Operating leases

Our corporate headquarters are located in Montrouge, France. Our principal offices occupy a 4,470 square meter facility, pursuant to a lease agreement dated March 3, 2015 and represents a $3.9 million cash requirement as of March 31, 2022 which expires March 8, 2024.



We also have facilities in North America that were initially intended to support
our U.S. subsidiary as well as future commercialization needs. We lease 3,780
square feet of office space in Tower 49, New York, New York. This lease is for a
period of 65 months and expires on February 25, 2023. In light of our global
restructuring, the current stage of regulatory interactions regarding Viaskin
Peanut, and the ongoing
COVID-19
pandemic, we entered into a sublease agreement of this office space in June
2021. The NYC office represents a $0.3 million cash requirement as of March 31,
2022 until the first quarter of 2023.

On March 28, 2022, the Company entered into a binding office lease agreement in
New Jersey for a lease term of 3 years and 2 months. The lease commencement was
based upon delivery of possession of the premises by the Landlord and occurred
on April 1, 2022. Right of use and related lease debt will be recorded starting
April 1, 2022.

Purchase obligations - Obligations Under the Terms of CRO Agreements

Viaskin Milk, we signed agreements with several contract research organizations.

with these contracts through 2024 is $33.1 million.
