First, as we recovered the rights for countries, other than Japan, covered under the agreement with Sumitomo Pharma, we have already engaged in partnering discussions to develop and market Imeglimin in China, the world's second-largest type 2 diabetes market, and other regions where Imeglimin can potentially be quickly developed and approved. We are also looking forward to the results of the discussions by Sumitomo Pharma with the regulatory authorities in Japan on revising TWYMEEG® package insert for type 2 diabetic patients with renal impairment, anticipated in FY 20243. For PXL770 and PXL065, we aim to finalize discussions with several potential partners before deciding on our investment decisions and development strategies,” stated Thomas Kuhn, Chief Executive Officer of Poxel. TWYMEEG® (Imeglimin) For the quarter ended June 2024, TWYMEEG® gross sales in Japan increased by 62% to JPY 1.7 billion (EUR 10.1 million)4 over the prior quarter sales of JPY 1.1 billion (EUR 6.6 million)5 as reported by Sumitomo Pharma. For its FY 20243, Sumitomo Pharma forecasts6 gross sales for TWYMEEG® of JPY 11.3 billion (EUR 69.1 million)2 which would represent a 150% increase over FY 2023 TWYMEEG® gross sales. During Sumitomo Pharma FY 20243, Poxel expects TWYMEEG® net sales in Japan to reach at least JPY 5 billion (EUR 31.3 million)4 entitling Poxel to receive 10% royalties on all TWYMEEG® net sales and a sales-based payment of JPY 500 million (EUR 3.1 million)4. Based on this FY 2024 forecast, TWYMEEG® net sales could also reach JPY 10 billion (EUR 62.6 million)4 entitling Poxel to receive 12% royalties on all TWYMEEG® net sales and a second sales-based payment of JPY 1 billion (EUR 6.3 million)4. Based on the recent royalty monetization agreement with OrbiMed, these proceeds for FY2024 will go the reimbursement of the bonds issuance. Beyond 2024, Poxel expects to receive escalating double-digit royalties as well as additional sales-based payments upon achievement of contractually based sales thresholds. As announced on August 7, 2024, topline results obtained from the post-marketing clinical study, TWINKLE (TWYMEEG® in diabetic patients with renal impairment: A post-marketing long-term study) conducted by Sumitomo Pharma in Japanese type 2 diabetic patients with renal impairment confirmed TWYMEEG®’s safety and tolerability profile, which is consistent with prior clinical studies in the general type 2 diabetes population. Based on these results, Sumitomo Pharma is planning to conduct discussions with the regulatory authorities in Japan during its FY 20243, on revising TWYMEEG® package insert for patients with renal impairment with eGFR (estimated glomerular filtration rate) less than 45 ml/min/1.73m2. In parallel of the non-dilutive financing agreement with OrbiMed, Poxel recovered the Imeglimin rights for Asian countries other than Japan7 from Sumitomo Pharma8. The Company has already initiated discussions to develop and market Imeglimin in China, the world's second largest type 2 diabetes market. Royalty monetization agreement based on TWYMEEG® sales with OrbiMed, and concurrent debt restructuring with IPF Partners and PGE banks9 Under the terms of the agreement, Poxel received a gross upfront payment of USD 50 million from the OrbiMed funds in exchange for an issuance of its bonds in the same aggregate amount. From such proceeds, a deposit of USD 7.5 million has been made by the Company into a deposit account, from which USD 1.25 million will be withdrawn quarterly and paid in partial repayment of the bonds issued to OrbiMed, until net sales of TWYMEEG® reach JPY 5 billion (USD 31.3 million4), at which point OrbiMed will begin to receive sales-based payments and royalties (anticipated in early 2025, based on the expected achievement of this sales threshold by the end of 20243). The residual amount of the deposit will then be available to the Company, in addition to the USD 42.5 million deposit received upon signature of the agreement. For the bonds issued by Poxel, the OrbiMed funds will receive (i) royalties payable by Sumitomo Pharma on net sales of TWYMEEG® in Japan, net of Poxel's obligation to Merck Serono, (ii) sales-based payments due by Sumitomo Pharma in connection with the commercialization of TWYMEEG® in Japan, and (iii) a portion of the cash flows received by the Company, in the event of partnership for the development and commercialization of Imeglimin in Asian countries other than Japan7. The agreement will expire, and the bonds deemed repaid once OrbiMed receives a capped return equivalent to 2 times its investment, i.e. USD 100 million, plus specified expenses, if any. Upon such repayment, Poxel will regain full rights to TWYMEEG® royalties in Japan and to any sales-based commercial payments and will use the majority of these proceeds to repay the outstanding amount owed to IPF Partners. Part of the bonds issuance amount from this transaction was used to reduce significantly the Company's debt towards IPF Partners and the PGE banks: EUR 23.7 million for partial repayment of IPF debt, reducing it to EUR 12.3 million; and EUR 2.8 million for partial repayment of the debt to the banks that granted the PGE Loan, reducing it to EUR 3 million. Consequently, the Company amended its agreements respectively with IPF Partners and the banks that granted a PGE loan for the repayment of the outstanding principal of each of these debts. Financial Statements for Full Year 2023 (IFRS Standards) Income statement *Net of R&D tax credit. The audit procedures are ongoing. Poxel reported revenues of EUR 2.0 million for the year ended December 31, 2023, as compared to EUR 0.674 thousand during the corresponding period in 2022. Revenues for 2023 mostly reflects the JPY 313 million (EUR 2.0 million) of royalty revenue from Sumitomo Pharma, which represents 8% of TWYMEEG® net sales in Japan. Cost of sales amounted to EUR 1.980 million, corresponding to the 8% royalties on net sales of Imeglimin in Japan due to Merck Serono, as part of the Merck Serono license agreement. R&D expenses totaled EUR 3.8 million in 2023, as compared to EUR 12.4 million in 2022. The 2023 decrease primarily reflects the end, in 2022, of the positive Phase 2 DESTINY study evaluating PXL065 in MASH. R&D costs are net of the R&D Tax Credit (CIR) and other subsidies that resulted in income of EUR 0.6 million in 2023, as compared to EUR 1.5 million in 2022. As presented in the Company’s half-yearly financial results 2023, the amount of amortization and depreciation of intangible assets includes exclusively the impairment of PXL065 for EUR 16.6 million. This impairment translates the Company's need to obtain additional financing to pursue its development plan in MASH or ALD, its current market capitalization and the macroeconomic context in which it operates. However, the Company considers that the potential of PXL065 in its targeted indications remains unchanged and very promising. General and administrative expenses totaled EUR 8.4 million in 2023, as compared to EUR 9.4 million in 2022. The financial loss amounted to EUR 6.3 million in 2023, as compared to a loss of EUR 9.5 million in 2022. It primarily reflects the interests attached to the Company indebtedness. The net result for the financial period ending December 31, 2023, was a net loss of EUR 35.1 million, as compared to a net loss of EUR 31.4 million in 2022. Cash Following the non-dilutive financing agreement with OrbiMed, and according to Poxel's current forecasts, including in particular: The Company’s cash position estimated, as of August 31st, 2024, at EUR 2,9 million the net upfront of USD 42.5 million (EUR 38,1 million4) from the monetization of royalties from TWYMEEG® sales; the partial redemption of the IPF Partners bond loan and the PGE loans for a total amount of EUR 26,5 million the advisory fees linked to the transaction the full residual drawdown of the equity-linked financing facility put in place with IRIS10;and the anticipated business plan including strict control of its operating expenses; the Company expects that its resources will be sufficient to finance its operations and capital expenditures until the end of 2025. 2023 Universal Registration Document The Company will make its 2023 Universal Registration Document in French available to the public and file it with the Autorité des marchés financiers no later than October 11, 2024.

OSAKA, Japan & LYON, France--( BUSINESS WIRE )--Regulatory News: Sumitomo Pharma Co., Ltd. (Head Office: Osaka, Japan; Representative Director, President and CEO: Toru Kimura) and POXEL SA (Euronext : POXEL - FR0012432516), a clinical stage biopharmaceutical company developing innovative treatments for chronic serious diseases with metabolic pathophysiology, including non-alcoholic steatohepatitis (NASH) and rare metabolic disorders, announced today topline results obtained from a post-marketing clinical study, TWINKLE ( TW YMEEG ® in d i abetic patients with re n al impairment: A post-mar k eting l ong-t e rm study) (“ the Study ”), in Japanese type 2 diabetic patients with renal impairment for TWYMEEG ® Tablets 500 mg (generic name: imeglimin hydrochloride, “ the Drug ”) being sold in Japan, based on the Risk Management Plan. The Study was an open-label, uncontrolled, long-term study in 60 Japanese type 2 diabetic patients with renal impairment, who had no experience of type 2 diabetes treatment other than diet and exercise therapy or insufficient glycemic management in monotherapy with a hypoglycemic agent excluding insulin formulation. The Drug was administered at 500 mg twice-daily to patients with moderate and severe renal impairment, characterized by an estimated glomerular filtration rate (eGFR) between 15 mL/min/1.73 m 2 or higher to less than 45 mL/min/1.73 m 2 , or at 500 mg once-daily to patients with end-stage renal disease, characterized by an eGFR less than 15 mL/min/1.73m 2 , in monotherapy or in combination therapy with a hypoglycemic agent excluding insulin formulation, to evaluate safety and tolerability when administered orally for 52 weeks. The Drug was observed to be safe and well tolerated in Japanese type 2 diabetic patients with renal impairment and no significant differences were found in the incidence of adverse events, their types and severities in this study from previous clinical studies. Specifically, most of the adverse events were mild or moderate in severity. The incidence of serious adverse events was 16.7% (10 of 60 subjects) and causality with the Drug could be ruled out in all cases. Incidence of adverse events leading to study treatment discontinuation was also limited (4 of 60 subjects). At present, administration of the Drug is not recommended for patients with renal impairment with eGFR less than 45 mL/min/1.73m 2 . Based on the results of the Study, Sumitomo Pharma is planning to conduct discussions with the regulatory authorities in Japan, on revising the package insert in fiscal 2024 1 for patients with renal impairment with eGFR less than 45 mL/min/1.73m 2 . About TWYMEEG ® TWYMEEG ® is the first agent in a class of tetrahydrotriazine-containing molecules. It is thought that the Drug shows a glucose lowering effect by both a pancreatic action that promotes glucose concentration-dependent insulin secretion and an extra-pancreatic action that improves glucose metabolism in the liver and skeletal muscle (suppression of gluconeogenesis and improvement of glucose uptake), through acting on mitochondria. The Drug has the potential to prevent endothelial and diastolic dysfunction, which could provide protective effects on micro- and macrovascular defects induced by diabetes. It may also have protective effects on pancreatic β cell survival and function. Owing to its unique mechanism of action, the Drug is widely used for glucose lowering in the treatment of type 2 diabetes, either as monotherapy or as an add-on to other therapies for this purpose. In October 2017, Sumitomo Pharma concluded a development and commercialization partnership agreement for Japan, Chinese mainland, Taiwan, Korea and nine Southeast Asian countries with Poxel SA (Head Office: Lyon, France; CEO: Thomas Kuhn) and started selling the Drug in Japan in September 2021. About Sumitomo Pharma Co., Ltd. Sumitomo Pharma Group defines its Mission as "To broadly contribute to society through value creation based on innovative research and development activities for the betterment of healthcare and fuller lives of people worldwide." By pouring all our efforts into the research and development, the Group aims to provide innovative and valuable pharmaceutical and healthcare solutions to people in Japan and around the world in order to realize its Mission.
