JERSEY CITY, N.J. & SHANGHAI--(BUSINESS WIRE)--SCYNEXIS, Inc. (NASDAQ: SCYX), a biotechnology company pioneering innovative medicines to overcome and prevent difficult-to-treat and drug-resistant infections, and Hansoh Pharmaceutical Group Company Limited (�Hansoh Pharma�, 3692:HK), one of the leading biopharmaceutical companies in China, today announced a strategic partnership and license agreement for the development and commercialization of Ibrexafungerp for the Greater China region.

Ibrexafungerp is a first-in-class, broad-spectrum triterpenoid antifungal agent providing the therapeutic advantages of both intravenous and oral formulations. It is currently under review by the U.S. Food and Drug Administration (FDA) for the treatment of vaginal yeast infections, and in late-stage development for multiple indications, including life-threatening fungal infections in hospitalized patients.

�We are excited and honored to partner with Hansoh Pharma given their strong experience in the infectious disease space and their exceptional development, manufacturing and commercial capabilities in Greater China.� said Marco Taglietti, M.D., President and Chief Executive Officer of SCYNEXIS. �This agreement represents a major step forward for ibrexafungerp in the global market, as resistance to azoles grows and deadly fungal infections such as Candida auris continue to emerge worldwide. This partnership not only provides non-dilutive funding to our Company but also further validates the potential of ibrexafungerp as a global anti-fungal franchise. We continue to seek other opportunities to monetize our global rights and leverage ibrexafungerp�s long-lasting patent exclusivity.�

Aifeng Lyu, Ph.D., President of Hansoh Pharma, added, �Antifungal resistance is on the rise, posing a global health threat, and with only three classes of antifungal drugs on the market, we recognize the urgent need for more effective antifungal therapies. We believe in ibrexafungerp�s potential to address this need and we are confident that with our integrated R&D, manufacturing, and commercial infrastructure, we can make ibrexafungerp a significant commercial success in Greater China. We look forward to working with SCYNEXIS to bring this novel and differentiated antifungal to patients in Greater China.�

Under the terms of the agreement, Hansoh shall be responsible for the development, regulatory approval, and commercialization of ibrexafungerp in Greater China. SCYNEXIS will receive a $10 million upfront payment and will also be eligible to receive development and commercial milestones, plus low double-digit royalties on net product sales.

About Ibrexafungerp

Ibrexafungerp is an oral antifungal product candidate under regulatory review for the treatment of vaginal yeast infection also known as vulvovaginal candidiasis (VVC). Its mechanism of action is fungicidal against Candida species, meaning it kills fungal cells. In December 2020, the U.S. Food and Drug Administration (FDA) accepted a New Drug Application for ibrexafungerp and granted a Prescription Drug User Fee Act (PDUFA) action date of June 1, 2021. The NDA is supported by positive results from two Phase 3, randomized, double-blind, placebo-controlled, multi-center studies (VANISH-303 and VANISH-306), in which oral ibrexafungerp demonstrated statistically superior efficacy and a favorable tolerability profile in women with VVC. If approved, this could be the first new antifungal class in over 20 years, and the first and only non-azole treatment for vaginal yeast infections.
