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
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. 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.
I
n the second quarter of 2021, we initiated PREQUAL, a Phase 1 study in healthy
adult volunteers to optimize the allergen sample collection methodologies and
validate the assays we intend to use in EQUAL (EQuivalence in Uptake of ALergen)
to demonstrate the protein uptake comparability of the modified patch (mVP) to
the reference or current patc
h (cVP).
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 FDA on May 6, and
received feedback from the FDA on October 14, 2021. The FDA has requested us a
stepwise approach to our modified Viaskin Peanut (mVP) development program. The
FDA would like us to review the data from our protein uptake release study prior
to providing additional comments on the STAMP protocol design. In its
communication, the FDA stated that guidance is forthcoming on how best to
demonstrate the protein uptake comparability of the mVP to the reference or
current patch (cVP). The STAMP trial will not be initiated until we receive
complete feedback from the FDA.
Viaskin
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.

  Table of Contents
In July 2021, we received from the EMA a 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.
M
any of EMA's Objections and Major Objections have been answered; one Major
Objection remained.
We are preparing our responses to the Day 180 letter and evaluating how to best
address the Objections, including the remaining Major Objection which questions
the limitations of the data, for example, the clinical relevance and effect size
supported by a single pivotal study. Further exchanges with EMA are anticipated.
We estimate the EMA could issue its decision on potential marketing
authorization for Viaskin Peanut in 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.

Our operating income is primarily generated from the French research tax credit
(
Cr
é

t
Recherche
, or
CIR
), and by the revenue recognized under our collaboration agreement with Nestlé
Health Science. We generated operating income of $1.3 million during the three
months ended September 30, 2021 compared to $4.2 million during the three months
ended September 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 the decrease in Research and
development expenses.
Research and Development Expenses

*Percentage not meaningful
Research and development expenses decreased by $9.4 million for the three months
ended September 30, 2021 compared to the three months ended September 30, 2020,
primarily due to a decrease in depreciation, amortization and other costs, as
well as in employee-related costs, partially offset by an increase in external
clinical-related expenses.
The decrease in depreciation, amortization and other costs was primarily due to
the decrease in inventory depreciation, as we wrote down any inventories and
work in progress to zero pending regulatory approval in the third quarter of
2020 following the CRL received from the FDA.This variation was partially offset
by 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.
Employee-related costs, excluding share-based payment expenses, decreased by
$2.6 million for the three months ended September 30, 2021, compared to the
three months ended September 30, 2020, due to the workforce reduction we
implemented as part of our 2020 global restructuring plan.
External clinical-related expenses increased by $3.5 million for the three
months ended September 30, 2021, compared to the three months ended
September 30, 2020, primarily due to the completion of CHAMP, the initiation of
PREQUAL and the preparation of the clinical protocol for STAMP.
The share-based payment expenses recognized for the three months ended
September 30, 2020 was triggered by the reversal of share-based payment expenses
due to employees' departures in the context of our restructuring plan.

Sales and marketing expenses amounted to $1.1 million for the three months ended
September 30, 2021, compared to $1.6 million for the three months ended
September 30, 2020. This decrease was primarily related to a decrease in
employee-related costs of $1.9 million due related to the workforce reduction
implemented as part of our restructuring plan.

*Percentage not meaningful


General and administrative expenses increased by $1.4 million for the three
months ended September 30, 2021 compared to the three months ended September 30,
2020 primarily due to the effect of exchange rates on external professional fees
and employee-related costs.
The share-based payment expense was nil for the three months ended September 30,
2020 mostly due to employees' departures in the context of our 2020 global
restructuring plan.
Restructuring expenses
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
September 30, 2021, our average headcount was 94, compared to 248 for the three
months ended September 30, 2020.
As of September 30, 2021, we had 92 employees. We expect full implementation of
the organization-wide cost reduction measures to be completed in the fourth
quarter 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 September 30, 2021.

Our operating income was primarily generated from the French research tax credit
(
CIR
) and from revenue recognized under our collaboration agreement with Nestlé
Health Science. We generated operating income of $2.8 million during the nine
months ended September 30, 2021, compared to $12.5 million during the nine
months ended September 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
expenses.
Research and Development Expenses
The following table summarizes our research and development expenses incurred
during the nine months ended September 30, 2021 and 2020:

                                                   Nine Months Ended

Research and development expenses decreased by $16.6 million for the nine months
ended September 30, 2021, compared to the nine months ended September 30, 2020,
primarily due to a decrease in employee-related costs and depreciation,
amortization and other costs, as well as in external clinical-related expenses,
offset by an increase in share-based payment expenses.
External clinical-related expenses decreased by $3.2 million for the nine months
ended September 30, 2021, compared to the nine months ended September 30, 2020,
primarily due to cost containment measures following our 2020 global
restructuring plan.
Employee-related costs, excluding share-based payment expenses, decreased by
$8.3 million for the nine months ended September 30, 2021 compared to the nine
months ended September 30, 2020 due to the workforce reduction we implemented as
part of our 2020 global restructuring plan.
The decrease in depreciation, amortization and other costs was primarily due to
the decrease in inventory depreciation, as we wrote down any inventories and
work in progress to zero pending regulatory approval in the third quarter of
2020 following the CRL received from the FDA.This variation was partially offset
by 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.
The share-based payment income recognized for the nine months ended
September 30, 2020 was triggered by the reversal of share-based payment expenses
due to employees' departures in the context of our restructuring plan.
Sales and Marketing expenses
The following table summarizes our sales and marketing expenses incurred during
the nine months ended September 30, 2021 and 2020:

Sales and marketing expenses decreased by $5.1 million for the nine months ended
September 30, 2021, compared to the nine months ended September 30, 2020,
primarily due to a decrease in employee-related costs and external professional
services, partially offset by share-based payment expenses.
Employee-related costs, excluding share-based payments expenses, decreased by
$5.8 million for the nine months ended September 30, 2021, compared to the nine
months ended September 30, 2020 due to the workforce reduction we implemented as
part of our 2020 global restructuring plan.
External professional services decreased by $2.1 million for the nine months
ended September 30, 2021, compared to the nine months ended September 30, 2020,
primarily as a result of budget discipline measures. The share-based payment
expense recognized for the nine months ended September 30, 2021 and the income
recognized for the nine months ended September 30, 2020 was triggered by the
reversal of share-based payment expenses due to employees' departures in the
context of our restructuring plan.

* Percentage not meaningful


General and administrative expenses decreased by $0.6 million for the nine
months ended September 30, 2021 compared to the nine months ended September 30,
2020, primarily due to cost containment measures and decreased external
professional fees, partially offset by an increase in share-based payment
expenses.
The share-based payment expense recognized for the nine months ended
September 30, 2021 and the income recognized for the nine months ended
September 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.
Restructuring expenses
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 nine months ended
September 30, 2021, our average headcount was 105 compared to 291 for the nine
months ended September 30, 2020.
As of September 30, 2021, we had 92 employees. We expect full implementation of
the organization-wide costs reduction measures to be completed in the fourth
quarter 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 nine months ended September 30, 2021.
Financial income (expense)
Our financial income was $0.6 million for the nine months ended September 30,
2021 compared to a financial expense of $1.4 million for the nine months ended
September 30, 2020. This item mainly includes foreign exchange income and
expenses.
Income tax
Our income tax profit was $0.4 million for the nine months ended September 30,
2021. This income tax profit mainly resulted from US tax refunds. We did not
have any income tax profit for the nine months ended September 30, 2020.
Net loss
Net loss was $84.1 million for the nine months ended September 30, 2021,
compared to $120.1 million for the nine months ended September 30, 2020. Net
loss per share (based on the weighted average number of shares outstanding over
the period) was $1.53 and $2.23 for the nine months ended September 30, 2021 and
2020, respectively.
