CLINICAL DEVELOPMENT KEY EVENTS FOR THE FIRST HALF OF 2022 AND SINCE JUNE 30, 2022

Authorization by Health Canada to file a New Drug Submission for masitinib in the treatment of amyotrophic lateral sclerosis (ALS) under the Notice of Compliance with Conditions (NOC/c) policy

AB Science announced that Health Canada has granted authorization to file a New Drug Submission for masitinib in the treatment of amyotrophic lateral sclerosis (ALS) under the Notice of Compliance with Conditions (NOC/c) policy.

If granted, an NOC/c is authorization to market a drug with conditions. Such conditions will be discussed with Health Canada during the procedure.

An assessment named Advance Consideration, performed by a Health Canada Adjudicating Committee, is necessary before being granted authorization to file under NOC/c policy.

This assessment was made based on a pre-submission package sent by AB Science including, efficacy data of study AB10015, long-term survival data (75 months average follow-up from diagnosis) of study AB10015, and safety data.

An estimated 3,000 Canadians are currently living with ALS. Each year approximately 1,000 Canadians die from ALS. A similar number of Canadians are diagnosed with ALS each year.

Under the NOC/c policy, Health Canada has a target of 200 calendar days maximum to review the application.

Filing for conditional Marketing Authorization to the European Medicines Agency (EMA) for masitinib in the treatment of amyotrophic lateral sclerosis (ALS)

AB Science filed an application for conditional Marketing Authorization to the European Medicines Agency (EMA) for Alsitek (masitinib) in the treatment of amyotrophic lateral sclerosis (ALS). The application is based on results from the phase 2/3 AB10015 study and its long-term survival follow-up. Study AB10015 was a randomized, double-blind, placebo-controlled trial over a 48-week treatment period, conducted with 394 ALS patients and evaluating Alsitek in combination with riluzole versus riluzole alone.

This decision to file followed a pre-submission meeting held with the Committee for Medicinal Products for Human Use (CHMP) Rapporteur during which new data generated with Alsitek in ALS were presented, in particular, a clinical benefit in terms of a 25-month increase in median overall survival for patients with moderate ALS, which is a cohort that closely resembles newly diagnosed patients. During the pre-submission meeting, AB Science also presented how issues listed in the previous CHMP assessment for Alsitek on ALS (EMA/406203/2018) were resolved, in particular:

• The mode of action of Alsitek in ALS, which has been well-demonstrated and published in peer-reviewed publications.
• A remonitoring of all efficacy and safety data and a complete reassessment of the Alsitek safety database.
• Additional analyses for the primary efficacy endpoint, imputing all missing data for early discontinuation, and a conservative analysis imputing missing data with a penalty for patients who discontinued Alsitek for lack of efficacy or toxicity. These analyses were positive, and all showed a treatment effect in favor of Alsitek and convergent with the primary analysis.
• Long-term follow-up survival data showing a significant benefit in favor of Alsitek in moderate ALS patients (between group difference in median OS of +25 months, hazard ratio 0.56 (95%CI [0.32;0.96])).

This application has now been validated by EMA and review by the CHMP has begun. The CHMP has a target of 210 active evaluation days to review the application.

Launch of a confirmatory Phase 3 study with masitinib in progressive forms of multiple sclerosis

AB Science announced that it has been authorized by the French Medicine Agency, ANSM, to initiate a Phase III study (AB20009) evaluating masitinib in patients with Primary Progressive Multiple Sclerosis (PPMS) or non-active Secondary Progressive Multiple Sclerosis (nSPMS). The study will enroll 800 patients from numerous study centers with Expanded Disability Status Scale (EDSS) score between 3.0 to 6.0 and absence of T1 Gadolinium-enhancing brain lesions as measured by magnetic resonance imaging (MRI).

The primary objective of the study will be to evaluate the effect of masitinib on time to confirmed disability progression, with progression defined as 1-point worsening when EDSS baseline score ≤5.5, or 0.5 if baseline score >5.5 from randomization to week 96.

This confirmatory study follows successful completion of a first Phase 2B/3 study (AB07002) in primary progressive (PPMS) and non-active secondary progressive (nSPMS) multiple sclerosis. This study met its primary analysis endpoint, demonstrating a statistically significant reduction in cumulative change on EDSS with masitinib 4.5 mg/kg/day (p=0.0256).

Positive recommendation of the Data and Safety Monitoring Board to continue both Phase 2 studies in Covid-19

AB Science announced the continuation of the Phase 2 study evaluating masitinib in combination with isoquercetin in COVID-19, following the recommendation of the Data and Safety Monitoring Board (DSMB). This randomized (1:1), open-label, phase 2 study (AB20001) is designed to evaluate the safety and efficacy of masitinib plus isoquercetin in hospitalised patients with moderate COVID-19 (WHO 7-point ordinal scale level 4) or severe COVID-19 (level 5). The study is planned to recruit 200 patients (over 18 years of age with no upper age limit). The primary objective is to improve the clinical status of patients after 15 days of treatment, as measured by the WHO 7-point ordinal scale.

The interim analysis was conducted with one third of the patients evaluated, as planned. The purpose of the interim analysis was to assess the safety and efficacy of the treatment. The DSMB recommends continuing the study without restrictions in moderate patients (level 4, i.e. hospitalized patients with oxygen supply <6 L/min with SpO2 maintained ≥92%). In line with this recommendation, AB Science has made the decision to continue the study only in moderate patients. The study is therefore now planned to include 200 patients at level 4 of the ordinal scale.

AB Science also announced the continuation of the second Phase 2 study evaluating the antiviral activity of masitinib in patients who have a confirmed diagnosis of COVID-19, following the recommendation of the Data and Safety Monitoring Board (DSMB). This randomized (1:1), double-blind, phase 2 study (AB21002) in 78 patients, is designed to evaluate the anti-viral efficacy of masitinib in non-hospitalized patients who are at risk of developing severe COVID-19 and in hospitalized patients with need of oxygen (via face mask or nasal cannula).

The analysis was to assess the safety of the treatment and was based on the first 50% of the patient targeted recruitment. The DSMB indicated that there was no safety concern and recommended continuation of the study without restrictions.

CONSOLIDATED FINANCIAL INFORMATION FOR THE FIRST HALF OF 2022

The operating loss as of June 30, 2022 was 9,562 K€, compared to a loss of 6,040 K€ as of June 30, 2021, i.e. an increase in the operating loss of 3,522 K€ (58.3%).

• Operating income, exclusively made up of sales related to the operation of a veterinary medicine, amounted to 629 K€ as of June 30, 2022 compared to 818 K€ one year earlier
• Operating expenses amounted to 10,192 K€ as of June 30, 2022, compared to 6,858 K€ as of June 30, 2021, an increase of 48.6%.
• Marketing expenses increased by 7.2% from 236 K€ as of June 30, 2021 to 253 K€ as of June 30, 2022.
• Administrative expenses increased by 26.9%, from 1,326 K€ as of June 30, 2021 to 1,682 K€ as of June 30, 2022.
• Research and development expenses increased by 2,800 K€, i.e 52.8 %, from 5,299 K€ as of June 30, 2021 to 8,099 K€ as of June 30, 2022. This variation is mainly explained by:
  • the decrease in the research tax credit (600 K€), due to the end of the doubling of subcontracting expenses to public research laboratories in the calculation of the research tax credit base from 2022,
  • the recognition at 30 June 2021 of income related to the cancellation of old accounts payable (860 K€), and
  • the recognition on 30 June 2022 of the valuation of warrants (414 K€)

The financial income as of June 30, 2022 is a gain of 2,424 K€ compared to a loss of 1,386 K€ one year earlier. The gain of 2,424 K€ as of 30 June 2022 is mainly related to the recognition of the change in fair value between 31 December 2021 and 30 June 2022 of the preference shares resulting from the conversion of the bonds in December 2016 (class C) and of the preference shares issued in September 2020 (class D), i.e. a financial gain of 2,244 K€ with no impact on cash over the period.

The net loss as of June 30, 2022 amounts to 7,141 K€ compared to a loss of 4,655 K€ as of June 30, 2021.

OTHER CORPORATE INFORMATION FOR THE FIRST HALF OF 2022 AND SINCE JUNE 30, 2022

Financing of USD 8.5 million through the issuance of bonds with attached warrants

AB Science reached an agreement with a historical investor on a financing of USD 8.5 million through the issuance of bonds convertible into new ordinary shares with attached warrants (OCABSA).

50,000 OCABSA will be issued, representing a nominal value of USD 8.5 million. It will reinforce the cash position of AB Science for the development of its clinical research program.

50,000 convertible bonds will be issued at their par value of USD 170,0 each (the “PV”), representing a total par value of USD 8.5 million.

Decision of the Enforcement Committee of the French market regulator (AMF) following the investigation relating to the financial information and the market for AB Science shares, opened in September 2017

On March 24, 2022, the AMF Enforcement Committee ruled that there was no privileged information, neither at the time of the two capital increases carried out by AB Science on March 24 and 27, 2017, nor at the time Alain Moussy sold a part of his shares on March 31, 2017. The AMF Enforcement Committee therefore completely exonerated Alain Moussy, prosecuted for insider trading, and found that AB Science had not failed to comply with its disclosure obligations at the time of these capital increases in March 2017.

The AMF Enforcement Committee nevertheless considered that AB Science should have communicated as early as April 7, 2017 the high probability of a negative opinion from the European Medicine Agency (EMA) on the marketing authorization application for masitinib for the treatment of mastocytosis and ordered AB Science to pay the sum of one million euros.

In application of its internal procedures, AB Science had nevertheless put in place a deferral of privileged information from this date of April 7, 2017, considering that the delay in communication was in the interest of the Company and in line with industry practices of not communicating before the final vote of the CHMP, or else withdrawing the registration dossier, which AB Science had no intention to do.

Given this difference in assessment concerning a technical point relating to one of the criteria for the deferred communication of privileged information, as well as the amount of penalty, AB Science has decided to appeal to the Paris Court of Appeal. The President of AMF also appealed against the Enforcement Committee's decision.
