SinoMab, Sinovent and Everest Medicines Announce Licensing Agreement for Global Development and Commercialization of A Next-Generation BTK Inhibitor in Renal Diseases
SinoMab and Sinovent will receive USD $12 million in upfront and up to $549 million in total development, regulatory, and commercial milestone payments

HONG KONG, Sept 17, 2021 - (ACN Newswire) - SinoMab BioScience Limited (HKEX 3681.HK, "SinoMab") announced with Suzhou Sinovent Pharmaceuticals Co., Ltd. ("Sinovent") today that they have entered into an exclusive licensing agreement with Everest Medicines (HKEX 1952.HK, "Everest") to out-license the right to develop and commercialize SN1011 (referred as "XNW1011" by Sinovent), a covalent reversible Bruton's tyrosine kinase (BTK) inhibitor, to Everest globally for the treatment of renal diseases.

Under the terms of the agreement, SinoMab and Sinovent will receive USD $12 million in initial upfront payments from Everest and up to $549 million as future development, regulatory, and commercial milestone payments, as well as high single-digit to low double-digit royalties on global net sales.

SN1011 is a next-generation covalent reversible BTK inhibitor that exhibits high selectivity, excellent pharmacokinetics property, robust target engagement and a safety profile that supports continued development based in part on results from a completed Phase 1 study with healthy subjects conducted by SinoMab in China.

This Phase I clinical trial is to evaluate safety, tolerability, pharmacokinetics, pharmacodynamics and recommended Phase II dose of SN1011 in the treatment of autoimmune disease. In this study, 71 healthy subjects were enrolled, and the highest dosage was ascended to 800 mg in single ascending study and 600 mg in multiple ascending study. None of the subjects reported serious adverse event (SAE). SN1011 is well tolerated with an excellent safety profile. Clinical study report is expected to be released by the end of the third quarter of this year. Following the approval of Investigational New Drug (IND) applications of SN1011 for pemphigus vulgar (PV) and systemic lupus erythematosus (SLE), SinoMab is initiating a Phase II clinical study targeting PV in China. The Company also plans to initiate a Phase II clinical study targeting SLE in near future.

Dr. Shui On LEUNG, Chairman, Executive Director and Chief Executive Officer of SinoMab, said, "Since our listing, SinoMab has been actively exploring and identifying opportunities for collaboration and partnership, including but not limiting to in-license and out-license of preclinical and clinical assets, to further strengthen our pipeline and expand our global presence. The out-license of SN1011 is a key milestone in our business development efforts. Alliance with Everest is not only recognition of the potential of SN1011, but also demonstration of the strength and rapid advancement of our pipeline.".
