Additional details are available in an updated corporate presentation that can be found online at About BX004 BiomX is developing BX004, a fixed multi-phage cocktail, for the treatment of CF patients with chronic pulmonary infections caused by P. aeruginosa, a main contributor to morbidity and mortality in patients with CF. In November 2023, BiomX announced positive topline results from Part 2 of the Phase 1b/2a study where BX004 demonstrated improvement in pulmonary function associated with a reduction in P. aeruginosa burden compared to placebo in a predefined subgroup of patients with reduced lung function1. BiomX expects to initiate a randomized, double blind, placebo-controlled, multi-center Phase 2b study in CF patients with chronic P. aeruginosa pulmonary infections in the fourth quarter of 2024. The study is designed to enroll approximately 60 patients randomized at a 2:1 ratio to BX004 or placebo. Treatment is expected to be administered via inhalation twice daily for a duration of 8 weeks. The study is designed to monitor the safety and tolerability of BX004 and is designed to demonstrate improvement in microbiological reduction of P. aeruginosa burden and evaluation of effects on clinical parameters such as lung function measured by FEV1 and patient reported outcomes. Study results are expected in the third quarter 2025. The U.S. Food and Drug Administration (“FDA”) has granted BX004 Fast Track designation and Orphan Drug Designation. 1 Predefined subgroup of patients with baseline ppFEV1<70% About BX211 BX211 is a personalized phage treatment developed by APT for the treatment of DFO associated with S. aureus. The personalized phage treatment tailors a specific phage selected from a proprietary phage-bank according to the specific strain of S. aureus biopsied and isolated from each patient. DFO is a bacterial infection of the bone that usually develops from an infected foot ulcer and is a leading cause of amputation in patients with diabetes. The ongoing randomized, double-blind, placebo-controlled, multi-center Phase 2 study investigating the safety, tolerability, and efficacy of BX211 for subjects with DFO associated with S. aureus is expected to enroll approximately 45 subjects randomized at a 2:1 ratio to BX211 or placebo. BX211 or placebo is designed to be administered weekly, by topical and IV route at Week 1 and by the topical route only at each of Weeks 2-12. Over the 12-week treatment period, all subjects are expected to continue to be treated in accordance with standard of care which will include antibiotic treatment as appropriate. A first readout of study topline results is expected at Week 13 evaluating healing of the wound associated with osteomyelitis, followed by a second readout at Week 52 evaluating amputation rates and resolution of osteomyelitis based on X-ray, clinical assessments, and established biomarkers (ESR and CRP). These readouts are expected in the first quarter of 2025 and the first quarter of 2026, respectively. About BiomX BiomX is a clinical-stage company developing both natural and engineered phage cocktails designed to target and destroy bacteria in the treatment of chronic diseases. BiomX discovers and validates proprietary bacterial targets and customizes phage compositions against these targets.

AGAMREE® is U.S. FDA approved and now available in the United States for the treatment of Duchenne muscular dystrophy (DMD) in patients 2 years of age and older This follows the first commercial launch of AGAMREE in Germany in January 2024 by Santhera AGAMREE is the first DMD treatment approved across the U.S., EU and UK Pratteln, Switzerland, March 14, 2024 – Santhera Pharmaceuticals (SIX: SANN) is pleased to note the launch of AGAMREE® (vamorolone) for the treatment of Duchenne muscular dystrophy (DMD) in the United States (U.S.) by Catalyst Pharmaceuticals, Inc. (NASDAQ: CPRX), the Company’s commercialization partner for North America. “Congratulations to our partner Catalyst on the launch of AGAMREE® in the United States. Following the first global market introduction of this novel product in Germany in January, this launch represents an important next step in making AGAMREE available to as many patients with DMD as soon as possible,” said Dario Eklund, CEO of Santhera. The launch of AGAMREE in the U.S. follows the approval of the product by the U.S. Food and Drug Administration (FDA) on October 26, 2023, based on data from the pivotal VISION-DMD study, recently published in Neurology, and supplemented with safety information collected from three open-label studies, including extension studies. According to the license agreement between the companies, first announced in June 2023, Catalyst holds an exclusive North American license to commercialize AGAMREE for DMD and all potential future indications. Under the agreement, Catalyst will pay Santhera sales-based milestones of up to USD 105 million as well as up to low-teen percentage royalties and will assume Santhera's corresponding third-party royalty obligations on AGAMREE sales in all indications in North America. Read more in Catalyst’s announcement here. About AGAMREE® (vamorolone) AGAMREE is a novel drug with a mode of action based on binding to the same receptor as glucocorticoids but modifying its downstream activity. Moreover, it is not a substrate for the 11-β-hydroxysteroid dehydrogenase (11β-HSD) enzymes that may be responsible for local drug amplification and corticosteroid-associated toxicity in local tissues [1-4]. This mechanism has shown the potential to ‘dissociate’ efficacy from steroid safety concerns and therefore AGAMREE is positioned as a dissociative anti-inflammatory drug and an alternative to existing corticosteroids, the current standard of care in children and adolescent patients with DMD [1-4]. In the pivotal VISION-DMD study, AGAMREE met the primary endpoint Time to Stand (TTSTAND) velocity versus placebo (p=0.002) at 24 weeks of treatment and showed a good safety and tolerability pro /> [1, 4]. The most commonly reported side effects were cushingoid features, vomiting, weight increase and irritability. Side effects were generally of mild to moderate severity. Currently available data show that AGAMREE, unlike corticosteroids, has no restriction of growth [5] and no negative effects on bone metabolism as demonstrated by normal bone formation and bone resorption serum markers [6]. AGAMREE (vamorolone), an orphan medicinal product, is approved for use in the United States (Prescribing Information), the European Union (Summary of Product Characteristics) and the United Kingdom.

About Duchenne Muscular Dystrophy Duchenne muscular dystrophy (DMD) is a rare inherited X-chromosome-linked disease, which almost exclusively affects males. DMD is characterized by inflammation which is present at birth or shortly thereafter. Inflammation leads to fibrosis of muscle and is clinically manifested by progressive muscle degeneration and weakness. Major milestones in the disease are the loss of ambulation, the loss of self-feeding, the start of assisted ventilation, and the development of cardiomyopathy. DMD reduces life expectancy to before the fourth decade due to respiratory and/or cardiac failure. Corticosteroids are the current standard of care for the treatment of DMD. About Santhera Santhera Pharmaceuticals (SIX: SANN) is a Swiss specialty pharmaceutical company focused on the development and commercialization of innovative medicines for rare neuromuscular and pulmonary diseases with high unmet medical need. The Company has an exclusive license from ReveraGen for all indications worldwide to AGAMREE® (vamorolone), a dissociative steroid with novel mode of action, which was investigated in a pivotal study in patients with Duchenne muscular dystrophy (DMD) as an alternative to standard corticosteroids. AGAMREE for the treatment of DMD is approved in the U.S. by the Food and Drug Administration (FDA), in the EU by the European Medicines Agency (EMA), and in the UK by the Medicines and Healthcare products Regulatory Agency (MHRA). Santhera has out-licensed rights to vamorolone for North America to Catalyst Pharmaceuticals, Inc. and for China to Sperogenix Therapeutics. The clinical stage pipeline also includes lonodelestat to treat cystic fibrosis (CF) and other neutrophilic pulmonary diseases. For further information, please visit .
