April 16, 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 scientific presentations on Basilea’s clinical-stage novel antifungal fosmanogepix given at ESCMID Global 2025, the annual meeting of the European Society of Clinical Microbiology and Infectious Diseases, which took place from April 11 to 15, 2025 in Vienna, Austria. Further presentations covered the antifungal isavuconazole (Cresemba®) and the antibiotic ceftobiprole (Zevtera®). Dr. Marc Engelhardt, Chief Medical Officer of Basilea, said: “Invasive fungal infections are an increasing global health problem and novel antifungals are urgently needed. To date more than 250 patients suffering from difficult-to-treat invasive fungal infections have received fosmanogepix via expanded access. The data presented at ESCMID highlight the potential of fosmanogepix as a life-saving treatment option in severe fungal infections, based on the results from a large cohort of patients with invasive fusariosis, as well as from patients with mucormycosis, who received fosmanogepix via expanded access. We look forward to the start of our second phase 3 study with fosmanogepix covering a broad range of mold infections, including aspergillosis, fusariosis and mucormycosis.” More than 250 patients from 11 countries with serious or life-threatening invasive fungal infections, who progressed on antifungal standard-of-care treatment, experienced treatment-limiting toxicities, or had infections with resistant fungal pathogens, received fosmanogepix via expanded access to date (NCT06433128). As presented at ESCMID, treatment with fosmanogepix resulted in favorable response rates of 70% or higher in patients with invasive fusariosis or mucormycosis and it was tolerated for long treatment durations. Further presentations reported on the activity of fosmanogepix against diverse yeast and mold species collected as part of a worldwide surveillance program. — Presentation IPT13: Fosmanogepix – a novel clinical phase 3 stage antifungal agent – M.

Funk, I. Khan, J. Li, J. Cusumano 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.2 Fosmanogepix has received Fast Track and Orphan Drug designations from the US Food and Drug Administration for seven separate indications, and is designated as a Qualified Infectious Disease Product (QIDP). This project has been funded in part with federal funds from the U.S. Department of Health and Human Services (HHS); Administration of Strategic Preparedness and Response (ASPR); Biomedical Advanced Research and Development Authority (BARDA), under OT number: 75A50124C00033. The contract and federal funding are not an endorsement of the study results, product, or company. Cresemba, with the active ingredient isavuconazole, is an intravenous (i.v.) and oral azole antifungal. In the 27 European Union member states, as well as in Iceland, Liechtenstein and Norway, isavuconazole is approved for patients aged from 1 year of age and older for the treatment of invasive aspergillosis and for the treatment of mucormycosis in patients for whom amphotericin B is inappropriate.3 Isavuconazole is also approved in the United States (US)4 and several additional countries in Europe and beyond, including the United Kingdom5, the Middle East and North Africa region, the Asia Pacific region, China and Japan.6 It has orphan drug designation in the US, Europe and Australia for its approved indications. Ceftobiprole, the active moiety of the prodrug ceftobiprole medocaril, is an advanced generation cephalosporin antibiotic for intravenous administration, with rapid bactericidal activity against a wide range of Gram-positive bacteria, such as Staphylococcus aureus, including methicillin-resistant strains (MRSA), and Gram-negative bacteria.7 In several countries in Europe and beyond, the brand is currently approved and marketed as Zevtera® and Mabelio® for the treatment of adult patients with hospital-acquired bacterial pneumonia (HABP), excluding ventilator-associated bacterial pneumonia (VABP), and for the treatment of community-acquired bacterial pneumonia (CABP).7 In the United States, ZEVTERA® is indicated for the treatment of adult patients with Staphylococcus aureus bloodstream infections (bacteremia) (SAB), including right-sided infective endocarditis, and adult patients with acute bacterial skin and skin structure infections (ABSSSI) and for adult and pediatric patients (3 months to less than 18 years old) with community-acquired bacterial pneumonia (CABP).8 Basilea is a commercial-stage biopharmaceutical company founded in 2000 and headquartered in Switzerland.

· Data from five European countries demonstrates the effectiveness of cefiderocol against Gram-negative pathogens considered as high or critical priorities by the WHO, including high rates of clinical cure and day 28 survival across patients with limited treatment options.1,2 · New European cohort data from the largest real-world evidence study of cefiderocol indicates a lower clinical cure rate trend among patients who received cefiderocol as salvage therapy compared with patients who received documented or empirical treatment.3 OSAKA, Japan, 8th April , 2025 – Shionogi & Co., Ltd. (Head Office: Osaka, Japan; President & CEO: Isao Teshirogi, Ph.D.; hereafter “Shionogi”) presents new European data from its largest real-world evidence study of Fetroja®/Fetcroja® (cefiderocol), an innovative siderophore cephalosporin at the 35th Congress of the European Society of Clinical Microbiology and Infectious Diseases in Vienna on 11th-15th April 2025. The PROVE (Retrospective Cefiderocol Chart Review) study is a five-year international, retrospective, observational medical chart review study, conducted between November 2020 and July 2024 designed to describe the efficacy and safety of real-world cefiderocol use in adult patients with serious Gram-negative (GN) bacterial infections.1 Analysis of the European cohort found a higher clinical cure rate trend among patients who received cefiderocol for a documented infection (67.4%) or as empiric therapy (64.6%) as compared to those who received it as salvage therapy (58.2%).3 Professor Oliver Cornely, Director of Translational Research, University of Cologne, said: “These data suggest a trend towards worse clinical outcomes when the use of cefiderocol to treat Gram-negative bacterial infections is reserved as a last line treatment option compared with those who received the treatment earlier. This trend may offer clinicians new evidence to justify the early and effective use of cefiderocol in patients with suspected resistant infections.” The study analysed data from 567 patients hospitalised with confirmed GN bacterial infections, who were treated with cefiderocol for the first time for ≥72 hours across Spain, France, Italy, Germany and the United Kingdom.1 Carbapenem resistance rate was >70% among patients enrolled in the study.1 55.9% of patients were critically ill in the intensive care unit and 41.3% were receiving organ support at the point of cefiderocol initiation.1 Respiratory tract infection (RTI) was the most frequent infection site, reported in over 50% patients (299), followed by urinary tract infection in over 12% of patients (73).1 Patients in the study receiving cefiderocol across all pathogens achieved an overall clinical cure rate of 65.3%.1 The most frequent pathogens observed were Pseudomonas aeruginosa (41.3%), Acinetobacter baumannii (15.0%), and Enterobacterales (14.6%)1, which are identified as priority pathogens by the World Health Organisation2. A clinical cure rate of 73.1% was observed among patients with a Pseudomonas aeruginosa infection.1 Takuko Sawada, Board Director and Vice Chair, Shionogi & Co Ltd., said: “Antimicrobial resistance is one of the most pressing global health challenges of this century, resulting in the deaths of millions of people around the world each year. In order to support better patient outcomes, it is imperative that clinicians have access to the innovative treatments they need for appropriate use with the right patient at the right time. We remain committed to the research and development of essential medicines that will help tackle the growing threat of drug-resistant infection.” - Ends – About Shionogi & Co. Ltd.
