LONDON and JERSEY CITY, N.J., March 30, 2023 (GLOBE NEWSWIRE) -- GSK plc (LSE/NYSE: GSK) and SCYNEXIS, Inc. (NASDAQ: SCYX), today announced they have entered into an exclusive licence agreement for Brexafemme (ibrexafungerp tablets), a US FDA approved, first-in-class antifungal for the treatment of vulvovaginal candidiasis (VVC) and for reduction in the incidence of recurrent VVC (RVVC). This exclusive licence agreement gives GSK rights to commercialise Brexafemme for VVC and RVVC while continuing to develop ibrexafungerp, which is in phase III clinical trials for the potential treatment of invasive candidiasis (IC), a life-threatening fungal infection.
Infectious diseases and HIV represent around two-thirds of GSK’s pipeline. Brexafemme complements GSK’s first or best-in-class portfolio alongside late-stage antibiotics gepotidacin, potentially the first novel antibiotic for uncomplicated urinary tract infections (uUTI) in over 20 years, and tebipenem, a potential new treatment of complicated urinary tract infections (cUTI).
Luke Miels, Chief Commercial Officer, GSK said: “The challenge of antimicrobial resistance includes increasing rates of multi-drug resistant fungal infections. Brexafemme is a novel, approved antifungal medicine with a broad spectrum of activity against existing and emerging resistant strains of fungi. In addition, the transaction consolidates GSK’s synergistic portfolio of innovative late-stage antibiotics.”
VVC affects up to
David Angulo, M.D., President and Chief Executive Officer of SCYNEXIS said: “This agreement represents a major milestone for SCYNEXIS, maximising Brexafemme’s commercial potential in VVC and further validating our vision of the critical role for this first-in-class antifungal in invasive infections. We are thrilled to partner with GSK on this high-potential asset and will continue progressing ibrexafungerp’s phase III programme in invasive candidiasis (IC).”
IC is a life-threatening infection that affects the blood or internal organs. There are around 750,000 cases of IC every year worldwide.ii In the US, it is one of the most common causes of bloodstream infections in hospitalised patients and can lead to more extended hospital stays and higher associated costs.

About Brexafemme (ibrexafungerp tablets)
Brexafemme (ibrexafungerp tablets) is a novel oral glucan synthase inhibitor with a broad spectrum of activity including against emerging resistant threats. Its mechanism of action is similar to echinocandins, with fungicidal action against yeast (meaning it kills the fungus), versus fluconazole which is fungistatic (meaning it inhibits fungal growth). It was first approved in the US in 2021 for the treatment of VVC and is the first and only oral antifungal approved for both the treatment of VVC and the reduction of the incidence of RVVC. Brexafemme has proven activity against WHO-designated priority fungal pathogens such as Candida albicans. In addition, ibrexafungerp has shown activity against Candida auris, another WHO-designated priority fungal pathogen.

Although not life-threatening, VVC does cause severe itching, soreness, and vaginal irritation, interfering with normal sexual relations. These symptoms and manifestations are considerably magnified when attacks are frequent and recurrent and when the disease is refractory to conventional therapy.iii

About IC
IC is a life-threatening fungal infection caused by Candida that affects the blood or internal organs. In the US, it is one of the most common causes of bloodstream infections in hospitalised patients, leading to longer hospital stays, higher associated costs, and death. People at risk include patients with a prolonged stay in an Intensive Care Unit and those with a weakened immune system, e.g., chemotherapy or organ transplant.iv

GSK in infectious diseases
Infectious diseases and HIV represent around two-thirds of GSK’s pipeline and its primary focus for R&D.

In addition, in September 2022, GSK entered into an exclusive licence agreement with Spero Therapeutics, Inc. to add tebipenem HBr, another late-stage antibiotic and potential treatment for complicated urinary tract infections (cUTI), to its pipeline.
