Poxel Provides Corporate Update and Reports Cash and Revenue for the Third Quarter and Nine Months 2020

POXEL SA (Euronext ? POXEL ? FR0012432516), a biopharmaceutical company focused on the development of innovative treatments for metabolic disorders, including type 2 diabetes and non-alcoholic steatohepatitis (NASH), today provided a corporate update and announced its cash position and revenue for the third quarter and the nine months ended September 30, 2020.

"During the third quarter, we continued to make significant progress and accomplished a number of important clinical and corporate objectives, including reporting positive results from a Phase 2a proof-of-concept trial for PXL770, demonstrating its potential in NASH. These results are the first human clinical assessment of a direct AMPK activator and support longer-term evaluation of important histological endpoints, such as inflammation and fibrosis, and exploring subpopulations for further differentiation. The data also demonstrate that AMPK activation may lead to broader utility for the treatment of other chronic and rare metabolic diseases. In addition, we initiated a streamlined Phase 2 trial for PXL065 in NASH and strengthened our cash position with non-dilutive funding from a milestone payment of EUR 4 million for the Imeglimin New Drug Application (NDA) submission in Japan and the recent PGE loan of EUR 6 million from the French government," said Thomas Kuhn, CEO of Poxel.

"For the remainder of this year, we expect several upcoming milestones and events including finalization of the PXL770 Phase 2b clinical trial design, presentations for PXL770 and PXL065 at several scientific meetings as well as publishing results in peer-reviewed scientific journals and additional preclinical data related to our AMPK and deuterated-TZD platforms. Furthermore, our partner, Metavant, is in discussions with the U.S. Food and Drug Administration (FDA) regarding the Imeglimin Phase 3 program in type 2 diabetes patients with chronic kidney disease (CKD) stages 3b/4," added Thomas Kuhn, CEO of Poxel.

Clinical Development Updates

Imeglimin (Type 2 Diabetes)

• The Company worked closely with Sumitomo Dainippon Pharma on activities related to the J-NDA for Imeglimin for the treatment of type 2 diabetes, which was submitted in late July to the Pharmaceuticals and Medical Devices Agency (PMDA) to request approval for manufacturing and marketing. A target launch is expected in 2021². The J-NDA approval would trigger a milestone payment of EUR 14.2 million ($16.6 million)³.
• Phase 3 TIMES 2 and TIMES 3 trial results were presented at the 56^th EASD meeting, demonstrating that Imeglimin met its primary endpoints and objectives and was observed to exhibit a favorable safety and tolerability profile.
• Imeglimin results focused on safety benefits were presented at the 63^rd JDS meeting. Speakers included Professor Kohjiro Ueki, MD, PhD, Director, Diabetes Research Center, the National Center for Global Health and Medicine, Tokyo, Japan and Professor Wataru Ogawa, MD, PhD, Professor, Division of Diabetes and Endocrinology, Department of Internal Medicine, Kobe University, Graduate School of Medicine, Kobe, Japan. In the Phase 2b and Phase 3 TIMES trials, Imeglimin was observed to have a favorable safety profile at the dose of 1,000 mg with similar frequency and types of adverse events as in the placebo group, and specifically appeared to be unlikely to cause hypoglycemia. In addition, new preclinical results showed that Imeglimin has a novel mechanism of action regulating mitochondrial bioenergetics, with a partial inhibition of complex I and no inhibition on mitochondrial glycerol 3-phosphate dehydrogenase (mGPDH), a driver of lactate accumulation, which further differentiates Imeglimin from metformin.
• Metavant, the Company's partner for the U.S. and Europe, is in discussions with the FDA regarding the Imeglimin Phase 3 program in type 2 diabetes patients with chronic kidney disease (CKD) stages 3b/4.

PXL770 (NASH)

• The Phase 2a trial for the treatment of NASH met its primary efficacy endpoint; PXL770-treated patients achieved statistically significant improvement in the relative decrease in liver fat mass measured by magnetic resonance imaging-estimated proton density fat fraction (MRI-PDFF) at 12-weeks with a greater response in patients with type 2 diabetes⁴.
• In the Phase 2a trial, key secondary measures in PXL770-treated patients included statistically significant observed improvements in liver enzymes alanine transaminase (ALT) and hemoglobin A1c (HbA1c).
• In the Phase 2a trial, PXL770 was observed to be safe and well tolerated. The results support the development in NASH and also further evaluation for combination use with other agents. Additional data are currently being analyzed and the Company is working with key opinion leaders to finalize the Phase 2b clinical trial design for PXL770.
• Phase 2a results also support utility of AMPK activation in other chronic and rare metabolic diseases.
• Preclinical results presented at the 56^th EASD meeting showed PXL770 was observed to improve renal and cardiac disease in a preclinical model demonstrating utility for NASH co-morbidities and additional indications driven by metabolic dysfunction.
• Poxel anticipates presenting new data for PXL770 in a peer-reviewed format at scientific meetings and in scientific journals during the fourth quarter of 2020.

PXL065 (NASH)

• In early September 2020, a streamlined Phase 2 study was initiated to evaluate PXL065 in at least 120 biopsy-proven NASH patients with the aim to identify the optimal dose or doses for a Phase 3 registration trial. The results from this study are anticipated to be available during the first half of 2022.
• Poxel anticipates presenting new data for PXL065 in a peer-reviewed format at scientific meetings and in scientific journals during the fourth quarter of 2020.

Additional Development Opportunities

• The Company is currently evaluating additional research and development opportunities from its AMPK activation and deuterated TZD platforms as well as external opportunities with a focus on chronic and rare metabolic diseases.

Corporate Update

• In October, Poxel received financing approval from BNP Paribas, Bpifrance and CIC Lyonnaise de Banque for a total of EUR 6 million in the form of state-guaranteed loans (Prets Garantis par l'Etat, or PGE in France) in the context of the COVID-19 pandemic.

Third Quarter and Nine Months Ended September 30, 2020 Cash and Revenue

Cash

As of September 30, 2020, cash and cash equivalents were EUR 41.5 million (USD 48.6 million), as compared to EUR 37.2 million (USD 41.8 million) at December 31, 2019. Cash and cash equivalents net of financial liabilities (excluding IFRS16 impacts and derivative debts) were EUR 24.5 million as of September 30, 2020, as compared to EUR 27.4 million at December 31, 2019. In October 2020, Poxel received a EUR 6.0 million PGE loan from the French government, which is not reflected in the September 30, 2020 cash update.

Nine Months 2020 Revenue

Poxel reported revenues of EUR 6.6 million for the nine months ended September 30, 2020, as compared to EUR 26.0 million during the corresponding period in 2019 (historical).

Revenue for the first nine months of 2020 includes an allocated portion of the EUR 36.0 million upfront payment received from Sumitomo Dainippon Pharma relating to the strategic corporate partnership announced on October 30, 2017, as well as the residual Imeglimin Phase 3 program costs in Japan incurred during the first nine months of 2020 that were re-invoiced to Sumitomo Dainippon Pharma and the milestone payment that Poxel received from Sumitomo Dainippon Pharma for the submission of the Imeglimin J-NDA. Both the allocated portion of the upfront payment and the re-invoiced costs of the Phase 3 Trials of IMeglimin for Efficacy and Safety (TIMES) program are recognized based on the accounting percentage of the completion of this program, which has been completed, and therefore led to the decrease in revenue.

Note: A change in the accounting policy of revenue recognition method was reported as part of the fiscal year 2019 financial statements in a press release dated February 12, 2020. This resulted in an adjustment to the Sumitomo Dainippon Pharma partnership revenue recognition for the previous years.
