Clinical Development Updates

Type 2 Diabetes (TWYMEEG^®/Imeglimin)

• On June 23, the new drug application for the 500mg TWYMEEG^® tablets for the treatment of type 2 diabetes, was approved in Japan. The first-in-class drug with a unique dual mechanism of action was approved as a monotherapy and/or as an additional treatment to other glucose-lowering therapy regimens. Approval was based on positive results from various preclinical and clinical studies, including the Phase 3 TIMES (Trials of IMeglimin for Efficacy and Safety) program managed jointly by Poxel and Sumitomo Dainippon Pharma. The program included three pivotal trials to evaluate TWYMEEG^®'s efficacy and safety in over 1,100 patients. TWYMEEG^® met its primary endpoints and objectives, exhibiting a favorable safety and tolerability profile.
• Three presentations on Imeglimin were included in an oral session for large clinical studies at the 64^th Annual Meeting of the Japan Diabetes Society held in May. The presentations focused on the analysis and interpretation of clinical data derived from Phase 2 and Phase 3 (TIMES program) trials with Imeglimin in Japanese patients with type 2 diabetes.
• In January, Poxel regained all Imeglimin rights from Metavant. In the US and Europe, Poxel continues to explore options to move Imeglimin forward in Phase 3 in patients with type 2 diabetes with moderate to severe chronic kidney disease (CKD), including partnering activities.

Rare metabolic diseases (PXL065 and PXL770)

• In X-linked adrenoleukodystrophy (ALD), a rare disease affecting the nervous system and adrenal glands, Phase 2a clinical POC biomarker studies examining PXL065 and PXL770 are planned to initiate in early 2022 with data readouts anticipated by year end 2022. Two identical studies will enroll adult male ALD patients with adrenomyeloneuropathy (AMN), the most common form of the disease, and observe the effect of PXL065 and PXL770 over 12 weeks of treatment on pharmacokinetics, safety, and efficacy using relevant biomarkers, including the impact on elevated very long chain fatty acids (VLCFA), the hallmark plasma marker of the disease.
• In April, Dr. Sophie Bozec, Senior Vice President, R&D Pharmacology and Scientific Communication at Poxel, delivered a presentation at the Mitochondria-Targeted Drug Development Summit highlighting Poxel's scientific focus and deep expertise in mechanisms modulating cellular energy homeostasis and addressing mitochondrial dysfunction ? including showcasing the potential of Poxel's AMP-kinase (AMPK) activator and deuterium-stabilized thiazolidinedione (dTZD) platforms for rare disorders where mitochondrial dysfunction is a major pathogenic component.

NASH (PXL065 and PXL770)

• PXL065, deuterium-stabilized R-pioglitazone, is being evaluated for safety and efficacy in a streamlined Phase 2 trial, DESTINY1, for the treatment of NASH. Patient enrollment was completed in September 2021, with topline data anticipated approximately one year later. This 36-week trial in noncirrhotic biopsy-proven NASH patients will assess three doses of PXL065 compared to placebo in 123 patients. The results will be used to help identify the dose or doses for a Phase 3 registrational trial.
• Future development of PXL770, a first-in-class, oral direct AMPK activator, in NASH will be assessed pending results from the PXL065 Phase 2 trial in NASH and both Phase 2a POC studies in ALD.
• Dr. Kenneth Cusi and Dr. Vlad Ratziu each delivered presentations on PXL770 clinical studies at the European Association for the Study of the Liver (EASL) International Liver Congresstm (ILC), held from June 23-26, 2021. Dr. Cusi presented the results of the STAMP-NAFLD 12-week, randomized, controlled Phase 2a trial of PXL770 in 120 presumed NASH patients ? selected as a "Best of ILC" abstract. Dr. Ratziu presented the results from a 4-week PK/PD target engagement study of PXL770 in NAFLD patients.

Subsequent Events after the Period

• In July, Poxel announced it will pursue a strategic direction to focus its pipeline on high value, rare metabolic indications, to complement its commitment to NASH, with the goal of creating pipeline synergies, maximizing resources, and driving shareholder value.
• In July, ENYO Pharma SA announced positive results for Vonafexor (EYP001), an FXR agonist that was licensed from Poxel in 2015, in a Phase 2a study in NASH patients over 12 weeks and topline interim results from two ongoing Phase 2a studies in chronic hepatitis B patients.
• In August, Elizabeth Woo was appointed as Senior Vice President, Investor Relations, Public Relations & Corporate Communications. Elizabeth brings over 25 years of investor relations and biotech communications experience in initial public offerings, follow-on financings, market launches, and commercialized products. She is based in Boston.
• On September 16, Poxel's strategic partner, Sumitomo Dainippon Pharma, launched TWYMEEG^® 500mg tablets for the treatment of type 2 diabetes in Japan. Japan is the first country where the product has been approved. As part of the license agreement with Sumitomo Dainippon Pharma, Poxel is entitled to receive escalating double-digit royalties on net sales and sales-based payments (based on Poxel's current forecast) of up to JPY 26.5 billion (approximately EUR 200 million, USD 230 million)² in accordance with sales goals.
• In September, data for PXL770 was published online by Hepatology Communications, titled "Direct AMPK Activation Corrects NASH in Rodents Through Metabolic Effects and Direct Action on Inflammation and Fibrogenesis."

First Half 2021 Financial Results (IFRS standards)

Revenue

Poxel reported revenues of EUR 13.3 million for the six months ended June 30, 2021, as compared to EUR 6.4 million during the corresponding period in 2020.

Revenue for the first half of 2021 mostly reflects the JPY 1.75 billion (EUR 13.2 million) milestone payment from Sumitomo Dainippon Pharma which Poxel received in July 2021.

Limited review procedures have been performed by the auditors and the issuance of the report is in process.

Income Statement

R&D expenses totaled EUR 14.7 million for the first half of 2021, as compared to EUR 12.6 million for the corresponding period in 2020. R&D expenses for the first half of 2021 primarily reflect the clinical study costs incurred for the phase 2 DESTINY study evaluating PXL065 in NASH. To a lesser extent, they also reflect the Phase 2a clinical program cost of PXL770 for the treatment of NASH and the regulatory costs incurred over the period for TWYMEEG^®, for which the Company obtained marketing approval in June 2021.

R&D expenses are net of the R&D Tax Credit (CIR) that resulted in an income of EUR 1.6 million for the first half of 2021 as compared to the same level for the corresponding period of 2020.

General and administrative expenses totaled EUR 5.4 million for the first half of 2021, as compared to EUR 6.0 million for the first half of 2020.
