You should read the following discussion and analysis of our financial condition
and results of operations in conjunction with our unaudited condensed
consolidated financial statements and related notes included in Part 1, Item 1
of this Report and with our audited financial statements and related notes
thereto for the year ended December 31, 2020, included in our Annual Report on
Form
10-K
for the year ended December 31, 2020, filed with the Securities and Exchange
Commission on March 17, 2021, or the Annual Report. This discussion and other
parts of this Report contain forward-looking statements that involve risks and
uncertainties, such as statements of our plans, objectives, expectations and
intentions. Our actual results could differ materially from those discussed in
these forward-looking statements. Factors that could cause such differences are
discussed in the section of this Report titled "Special Note Regarding
Forward-Looking Statements" and under "Item 1A. Risk Factors" in the Annual
Report.
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
EPIT
TM
, 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.
Viaskin Peanut in the United States

On January 13, 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. We believe the FDA feedback provides a well-defined regulatory path
forward. In exchanges with the FDA, we proposed potential resolutions to two
main concerns identified by the FDA in the CRL: the impact of patch adhesion and
the need for patch modifications. 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 1/1000 of a 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 modified
patches, the FDA has requested an assessment comparing the uptake of allergen
(peanut protein) between the patches in peanut allergic children ages 4 to 11
years. The FDA also recommended conducting a 6-month, well-controlled safety and
adhesion trial to assess the modified Viaskin Peanut patch in the intended
patient population.

In the second quarter of 2021, we completed CHAMP (Comparison of adHesion Among
Modified Patches), a trial in healthy adult volunteers to evaluate the adhesion
of five modified Viaskin Peanut patches in order to identify the top performers.
Based on the adhesion parameters studied, we were pleased to learn that all
modified Viaskin Peanut patches demonstrated better adhesion performance as
compared to the current Viaskin Peanut patch. We then selected two modified
patches that performed best out of the five modified patches studied for further
development.

The difference between the two selected patches is their shape-one is circular
and the other is rectangular with rounded corners. They are both approximately
50% larger than the current patch but maintain the same structure of the
occlusion chamber (i.e., foam ring and backing). We also conducted advisory
boards with patient caregivers and key opinion leaders to obtain qualitative
feedback on the consumer experience with both patches.

We submitted the protocol for STAMP (Safety, Tolerability and Adhesion of
Modified Patches), the 6-month adhesion and safety study of the modified patch,
to the U.S. Food and Drug Administration (FDA) in the second quarter of 2021 and
are currently awaiting feedback.

Earlier this quarter, we initiated PREQUAL, a Phase 1 study in healthy adult
volunteers to optimize the allergen sample collection methodologies and validate
the assays DBV intends to use in EQUAL (EQuivalence in the Uptake of ALlergen).
We continue to work closely with the FDA on how to best demonstrate the protein
transport comparability of the modified patch (mVP) to the reference patch
(cVP).

ViaskinTM Peanut in Europe
During the first quarter of 2021, we received the first set of questions from
the European Medicines Agency, or EMA, regarding the Marketing Authorization
Application, or MAA, for Viaskin Peanut as a treatment for peanut allergy in
children ages 4-11.. The questions were consistent with our expectations and
prefiling conversations with the EMA. We did not receive questions about the
impact of adhesion on efficacy. The EMA's Committee for Medicinal Products for
Human Use will provide a recommendation to the European Commission, or EC, on
whether to grant a marketing authorization when its review of the Viaskin Peanut
MAA is complete.

The European Medicines Agency (EMA) review of the Viaskin Peanut Marketing
Authorization Application (MAA) is progressing according to established EMA
processes and ongoing conversations with the EMA.
In July 2021, we received from the EMA Day 180 list of outstanding issues. The
review of the Viaskin Peanut MAA is progressing according to established EMA
processes and ongoing conversations with the EMA.
Many of EMA's Objections and Major Objections have been answered; One Major
Objection remains. We will provide a response to address the outstanding issues,
including the mentioned Major Objection.

Based on the average length of an EMA evaluation of an MAA, we estimate the EMA
could issue its decision on potential marketing authorization for Viaskin Peanut
in the fourth quarter of 2021 or the first quarter of 2022.
Critical Accounting Policies and Significant Judgments and Estimates
Our management's discussion and analysis of our financial condition and results
of operations is based on our condensed consolidated financial statements, which
have been prepared in accordance with generally accepted accounting principles
in the United States, or U.S. GAAP. The preparation of these condensed
consolidated financial statements requires us to make estimates and assumptions
that affect the reported amounts of assets and liabilities and the disclosure of
contingent assets and liabilities at the date of the consolidated financial
statements, as well as the revenue, costs and expenses recognized during the
reporting periods. 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.
There have been no new policies or significant changes to our critical
accounting policies as disclosed in the critical accounting policies described
in the Annual Report. Our significant accounting policies are more fully
described in Note 1 of the Notes to the Condensed Consolidated Financial
Statements in Part I, Item 1 of our Annual Report.

Total operating income     (1,488 )      3,610        (5,098 )          (141 )%



Our operating income is primarily generated from the French research tax credit
(
Crédit d'Iimpôt Recherche
, or "CIR"), and by the revenue recognized under our collaboration agreement
with Nestlé Health Science. We generated operating income of $(1.5) million
during the three months ended June 30, 2021 compared to $3.6 million during the
three months ended June 30, 2020. The decrease in operating income is primarily
attributable to the change in the revenue recognized under the Nestlé's
collaboration agreement, as we updated the measurement of progress of the Phase
II clinical trial conducted as part of the agreement due to delays in new
patient enrollment. The decrease in research tax credit is attributable to the
decline of eligible expenses in connection with Research and Development costs.

Research and Development expenses decreased by $1.8 million for the three months
ended June 30, 2021 compared to the three months ended June 30, 2020, primarily
due to a decrease in external clinical-related expenses as a result of budget
discipline measures . Employee-related costs, excluding share-based payment
expenses, decreased by $0.8 million for the three months ended June 30, 2021
compared to the three months ended June 30, 2020 directly related to the
workforce reduction we implemented as part of our 2020 global restructuring
plan.
The shared-based payment income recognized for the three months ended June 30,
2020 was triggered by the reversal of share-based payment expenses due to
employees' departures in the context of our restructuring plan.
The increase of depreciation, amortization and other expenses relates primarily
to the change in the second quarter of 2021 in the accrual recorded in the
amount of the difference between our current best estimates of costs yet to be
incurred and revenues yet to be recognized for the completion of the Phase II
clinical trial conducted as part of the Nestlé agreement.

Sales and marketing expenses amounted to $1.2 million for the three months ended
June 30, 2021, compared to $(0.8) million for the three months ended June 30,
2020.
The shared-based payment income recognized for the three months ended June 30,
2020 was triggered by the reversal of share-based payment expense due to
employees' departures in the context of our 2020 global restructuring plan.
The increase in share-based payment expense for the three months ended June 30,
2021 compared to the three months ended June 30, 2020 was partly offset by the
decrease in employee-related costs, directly related to the workforce reduction
implemented as part of our restructuring plan. The decrease in external
professional services for the three months ended June 30, 2021 compared to the
three months ended June 30, 2020 is directly related to budget discipline
measures taken.

General and Administrative expenses decreased by $0.6 million for the three
months ended June 30, 2021 compared to the three months ended June 30, 2020
primarly due to cost containment measures and decreased external professional
fees.
The share-based payment income recognized for the three months ended June 30,
2020 was triggered by the reversal of share-based payment expense due to
employees' departures in the context of our 2020 global restructuring plan.
The decrease in employee-related costs, excluding share-based payments expenses,
was directly related to the workforce reduction we implemented as part of our
restructuring plan.
Restructuring
We initiated a global restructuring plan in June 2020 to provide operational
latitude to progress in the clinical development and regulatory review of
investigational Viaskin
™
Peanut in the United States and European Union. For the three months ended
June 30, 2021, our average headcount was 99, compared to 306 for the three
months ended June 30, 2020.
As of June 30, 2021, we had 97 employees. We expect full implementation of the
organization-wide cost reduction measures to be completed in the second half of
2021.
The restructuring costs were mainly comprised of payroll expenses,
restructuring-related consulting and legal fees, as well as impairment of
facilities and right of use assets following resizing of facilities.
There were no restructuring costs for three months ended June 30, 2021.
Financial income (expense)
Our financial income was approximately $46,000 for the three months ended
June 30, 2021 compared to a financial expense of $0.5 million for the three
months ended June 30, 2020. This item mainly includes foreign exchange income
and expenses.
Income tax
Our income tax profit was $0.4 million for the three months ended June 30, 2021.
This profit mainly resulted from U.S. tax refunds.
Net loss
Net loss was $30.7 million for the three months ended June 30, 2021, compared to
$48.2 million for the three months ended June 30, 2020. Net loss per share
(based on the weighted average number of shares outstanding over the period) was
$0.56 and $0.88 for the three months ended June 30, 2021 and 2020, respectively.

Total operating income      1,453        8,330        (6,877 )           (83 )%



Our operating income was primarily generated from the French research tax credit
(
Crédit d'Impôt Recherche
or "CIR") and from revenue recognized under our collaboration agreement with
Nestlé Health Science. We generated operating income of $1.5 million during the
six months ended June 30, 2021, compared to $8.3 million during the six months
ended June 30, 2020. The decrease in operating income is primarily attributable
to the change in the revenue recognized under the Nestlé's collaboration
agreement, as we updated the measurement of progress of the Phase II clinical
trial conducted as part of the agreement due to delays in new patient
enrollment.
The decrease in research tax credit is attributable to the decline in eligible
expenses in connection with Research and Development costs.

Research and Development expenses decreased by $7.1 million for the six months
ended June 30, 2021 compared to the six months ended June 30, 2020 primarly due
to a decrease in external clinical-related expenses as a result of budget
discipline measures . Employee-related costs, excluding share-based payments
expenses, decreased by $5.6 million for the six months ended June 30, 2021,
compared to the six months ended June 30, 2020 directly related to the workforce
reduction we implemented as part of our 2020 global restructuring plan.
The shared-based payment income recognized for the six months ended June 30,
2020 was triggered by the reversal of share-based payment expenses due to
employees' departures in the context of our restructuring plan.
The increase in depreciation, amortization and other expenses relates primarily
to the change in the second quarter of 2021 in the accrual recorded in the
amount of the difference between our current best estimates of costs yet to be
incurred and revenues yet to be recognized for the completion of the Phase II
clinical trial conducted as part of the Nestlé agreement.

Restructuring
We initiated a global restructuring plan in June 2020 to provide operational
latitude to progress the clinical development and regulatory review of
investigational Viaskin
™
Peanut in the United States and European Union. For the six months ended
