Ceftobiprole Medocaril Sodium

Ad hoc announcement pursuant to Art. 53 LR Allschwil, Switzerland, July 08, 2025 Basilea Pharmaceutica Ltd, Allschwil (SIX: BSLN), a commercial-stage biopharmaceutical company committed to meeting the needs of patients with severe bacterial and fungal infections, announced today that the Biomedical Advanced Research and Development Authority (BARDA), part of the Administration for Strategic Preparedness and Response (ASPR) within the U.S. Department of Health and Human Services, committed the next USD 39 million to Basilea to continue to advance the development of Basilea’s novel antifungals fosmanogepix and BAL2062. This additional funding is based on the successful completion of a milestone within the “Other Transaction Agreement” (OTA, agreement number 75A50124C00033) that was awarded on September 30, 2024, and which allows for potential funding of up to approximately USD 268 million in total to develop antifungal and antibacterial assets. David Veitch, Chief Executive Officer of Basilea, said: “We are very pleased to receive the continued funding under the OTA with BARDA to support the development of our antifungal drug candidates fosmanogepix and BAL2062. Both compounds offer a novel mechanism of action and represent new therapeutic options for patients with aspergillosis, candidiasis or other life-threatening fungal infections. These infections primarily affect patients with weakened immune systems, such as cancer or transplant patients. Infections with difficult-to-treat rare molds or with resistance to current therapies are increasing. Hence, there continues to be a high medical need for new innovative antifungals.” He added: “This second tranche of funding within the BARDA OTA will support the ongoing phase 3 study with fosmanogepix in yeast infections and the second phase 3 study, in mold infections, which is expected to start soon. It also provides funding for the preparation for the start of the phase 2 study for our antifungal BAL2062.” The USD 39 million is in addition to the initial USD 29 million BARDA committed at the signing of the OTA in September 2024. BARDA’s financial contribution is about 60% of the total costs of the supported projects over the term of the OTA, which could provide a total potential non-dilutive funding of up to approximately USD 268 million, over up to 12 years, if all additional options to extend the contract are exercised by BARDA, upon successful completion of pre-defined milestones, including clinical and regulatory activities. About fosmanogepix Fosmanogepix is a clinical-stage broad-spectrum antifungal. It has a novel mechanism of action and its active moiety has shown activity against common species of Candida and Aspergillus, including multi-drug-resistant strains, such as Candida auris and Candida glabrata, as well as rare difficult-to-treat molds including Fusarium spp., Scedosporium spp., and some fungi from the Mucorales order.1 Fosmanogepix intravenous and oral formulations have been evaluated in clinical phase 2 studies for the treatment of patients with Candidemia, including Candida auris infections, and invasive mold infections.1 A phase 3 study evaluating fosmanogepix in the treatment of adult patients with candidemia and/or invasive candidiasis is ongoing and the initiation of a second phase 3 study, in the treatment of adult patients with invasive mold infections, is expected soon.2 Fosmanogepix has received Fast Track and Orphan Drug designations from the U.S. Food and Drug Administration for a number of indications, and is designated as a Qualified Infectious Disease Product (QIDP). About BAL2062 BAL2062 is a first-in-class antifungal, derived from a natural product, and has demonstrated fungicidal activity against clinically important molds such as Aspergillus spp., including azole-resistant strains.3 Safety and tolerability have been demonstrated in a previously completed phase 1 study with single and multiple ascending intravenous (i.v.) doses.4 The drug candidate has Qualified Infectious Disease Product (QIDP), Orphan Drug and Fast Track designation from the US Food and Drug Administration (FDA) for invasive aspergillosis. About invasive mold infections Invasive aspergillosis and invasive infections with rare molds (e.g., Fusarium spp., Scedosporium spp., and Mucorales fungi) are life-threatening infections that predominantly affect immunocompromised patients, including patients with hematologic malignancies (blood cancer), transplant patients, or patients with other immunodeficiency disorders. These infections are associated with high morbidity and mortality.5, 6 About invasive candidiasis Invasive candidiasis, including deep-seated tissue candidiasis and candidemia, is an increasingly important nosocomial infection, especially in patients hospitalized in intensive care units. Candida species are ranked as the fourth main cause of bloodstream infections in hospitals in the US.7 The prognosis of invasive candidiasis remains difficult, with a reported mortality rate for invasive candidiasis as high as 40%, even when patients receive antifungal therapy.8 About Basilea Basilea is a commercial-stage biopharmaceutical company founded in 2000 and headquartered in Switzerland. We are committed to discovering, developing and commercializing innovative drugs to meet the needs of patients with severe bacterial and fungal infections. We have successfully launched two hospital brands, Cresemba for the treatment of invasive fungal infections and Zevtera for the treatment of bacterial infections. In addition, we have preclinical and clinical anti-infective assets in our portfolio. Basilea is listed on the SIX Swiss Exchange (SIX: BSLN). Please visit basilea.com.

FDA is expected to notify Innoviva Specialty Therapeutics regarding its decision to conduct an Advisory Committee Meeting in the Day 74 letter If approved, zoliflodacin would be the first new antibiotic for treating gonorrhea in decades WALTHAM, MA, USA & GENEVA, Switzerland I June 12, 2025 I Innoviva Specialty Therapeutics, Inc., a subsidiary of Innoviva, Inc. (NASDAQ: INVA), in collaboration with the Global Antibiotic Research & Development Partnership (GARDP), today announced that the U.S. Food and Drug Administration (FDA) has granted Priority Review for the New Drug Application (NDA) for zoliflodacin, an investigational first-in-class, single dose, spiropyrimidinetrione oral antibiotic for the treatment of uncomplicated gonorrhea in adults and pediatric patients 12 years and older. The FDA assigned a target action date of December 15, 2025 under the Prescription Drug User-Fee Act (PDUFA). It is expected the FDA will notify Innoviva Specialty Therapeutics regarding the FDA’s decision to conduct an Advisory Committee Meeting in the Day 74 letter. If approved, zoliflodacin would be the first new antibiotic for treating gonorrhea in decades. The U.S. FDA has granted zoliflodacin a Qualified Infectious Disease Product (QIDP) designation. This designation allows it to benefit from FDA Priority Review, and Extended Market Exclusivity. Entasis Therapeutics, Inc., the legal NDA holder and affiliate of Innoviva Specialty Therapeutics, Inc., retains the commercial rights for zoliflodacin in the major markets in North America, Europe, and Asia-Pacific. GARDP retains the right to register and commercialize the product in more than three-quarters of the world’s countries, including all low-income countries, most middle-income countries, and several high-income countries. GARDP is committed to working with its partners and local health authorities in markets where zoliflodacin receives regulatory approval to help remove access barriers to ensure treatment is available to address unmet medical needs while ensuring appropriate and sustainable use. About Uncomplicated Gonorrhea With more than 82 million new gonorrhea infections occurring globally each year, gonorrhea is the second most common bacterial sexually transmitted infection (STI), affecting both men and women, which, if left untreated, can result in serious and permanent health consequences. With the rise and spread of drug-resistant infections, the World Health Organization (WHO) has identified antimicrobial resistance (AMR) as one of the ten most critical global threats to public health. The bacterium Neisseria gonorrhoeae, which causes gonorrhea, has progressively developed resistance to most classes of antibiotics used to treat these infections, including ceftriaxone, a widely used intramuscular injection that was first made available in 1984. About Zoliflodacin Zoliflodacin is an investigational first-in-class antibacterial that is administered in a single oral dose for the treatment of uncomplicated gonorrhea. The oral route of administration simplifies treatment by providing a convenient option for patients unable to receive an intramuscular injection. Zoliflodacin has a unique mechanism of action, inhibiting a crucial bacterial enzyme called type II topoisomerase, which is essential for bacterial function and reproduction. In in vitro studies, zoliflodacin demonstrated activity against multidrug-resistant strains of Neisseria gonorrhoeae , including those resistant to ceftriaxone and azithromycin, with no cross-resistance to other antibiotics. In a pivotal Phase 3 clinical trial, zoliflodacin demonstrated non-inferiority in achieving microbiological cure at the urogenital site of infection with a single oral dose of zoliflodacin compared to a treatment regimen of a single intramuscular injection of 500mg ceftriaxone followed by 1g of oral azithromycin. The Phase 3 study found that zoliflodacin was generally well-tolerated, with no serious adverse events or deaths reported during the trial. About GARDP The Global Antibiotic Research & Development Partnership (GARDP) is a not-for-profit global health organization driven to protect people from the rise and spread of drug-resistant infections, one of the biggest threats to us all.
