Bacteremia

Phase 1b/2a diSArm trial evaluated AP-SA02 as a potential treatment for complicated Staphylococcus aureus bacteremia Topline data anticipated in Q2 2025 to support potential future pivotal bacteremia efficacy trial LOS ANGELES, May 1, 2025 /PRNewswire/ -- Armata Pharmaceuticals, Inc. (NYSE American: ARMP) ("Armata" or the "Company"), a biotechnology company focused on the development of high-purity, pathogen-specific bacteriophage therapeutics for the treatment of antibiotic-resistant and difficult-to-treat bacterial infections, today announced that it has received an additional $4.65 million of non-dilutive funding pursuant to a previously announced Department of Defense (DoD) award, received through the Medical Technology Enterprise Consortium (MTEC) and managed by the Naval Medical Research Command (NMRC) – Naval Advanced Medical Development (NAMD) with funding from the Defense Health Agency and Joint Warfighter Medical Research Program. The award, currently totaling $26.2 million, was awarded to Armata to support clinical development of its optimized phage candidate, AP-SA02, as a potential treatment for complicated Staphylococcus aureus bacteremia (SAB). The additional $4.65 million will be used to support Phase 2a study close out activities as well as for the preparation and execution of an end-of-phase 2 meeting with the U.S. Food and Drug Administration. "The DoD has been an essential partner throughout the development of AP-SA02, and we are very grateful for their continued support of this important program," stated Dr. Deborah Birx, Chief Executive Officer of Armata. "We remain committed to efficiently advance AP-SA02 through full clinical development and introduce this novel phage-based anti-infective for the benefit of military personnel and civilians alike." "At Armata, we remain laser focused on demonstrating, in rigorously designed placebo-controlled clinical trials, the potential of phage therapy to successfully combat evolving deadly bacteria, including systemic Staphylococcus aureus infections. In parallel, we have developed our proprietary manufacturing process with complete in-house U.S.-based capacity to support clinical development as well as full future commercial production. This not only allows us to be efficient but is also expected to ensure immediate access to patients in need if AP-SA02 is found to be effective," Dr. Birx concluded. The diSArm study is a Phase 1b/2a, randomized, double-blind, placebo-controlled, multiple ascending dose escalation study of the safety, tolerability, and efficacy of intravenous AP-SA02 as an adjunct to best available antibiotic therapy compared to best available antibiotic therapy alone for the treatment of adults with SAB. This study was conducted in two phases: Phase 1b evaluated the safety and tolerability of multiple ascending intravenous doses of AP-SA02 or placebo as an adjunct to best available therapy (BAT) compared to BAT alone in subjects with SAB. Phase 2a evaluated the efficacy, safety, and tolerability of multiple doses of AP-SA02 or placebo as an adjunct to BAT compared to BAT alone in subjects with complicated SAB. The study achieved full enrollment of 50 subjects in November 2024, with the last patient visit having taken place in January 2025. During the execution of the trial, Armata was able to dose escalate to 5e10 PFU every six hours (2E11 PFU every 24 hours) for five days without clinically significant adverse events. In parallel with dose escalation, the evolution of two distinct blinded subsets of subjects receiving phage has been observed. One subset, comprising approximately half of the treated group, has evidence of persistence of detectable phage in the blood consistent with in vivo phage amplification. This suggests that, despite the best available antibiotic treatment for greater than five days, reservoirs of active SAB remained that Armata's phages targeted, infected and killed before recirculating in the intravascular space. As of now, the Company anticipates receipt of topline data in the next few weeks, where it can explore the two aforementioned subsets in an unblinded manner. Topline results are also expected to inform the optimal dose of AP-SA02 to be evaluated in the larger definitive efficacy study. For more information on the diSArm study, see NCT05184764. In addition, Armata filed its Annual Report for the year ended December 31, 2024 on Form 10-K with the Securities and Exchange Commission (the "SEC") on March 21, 2025. The audit opinion included in the Company's Form 10-K for the year ended December 31, 2024 contains a going concern explanatory paragraph.

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.

Interim blinded safety and pharmacokinetic data to be presented at the Congress of the European Society of Clinical Microbiology and Infectious Diseases (ESCMID Global) ROCKVILLE, MD, USA I April 10, 2025 I Theriva Biologics (NYSE American: TOVX), (“Theriva” or the “Company”), a diversified clinical-stage company developing therapeutics designed to treat cancer and related diseases in areas of high unmet need, today announced the presentation of the previously disclosed blinded safety and pharmacokinetic (PK) data from the ongoing Phase 1b/2a randomized, double-blinded, placebo-controlled clinical trial of SYN-004 (ribaxamase) in allogeneic hematopoietic cell transplant (HCT) recipients for the prevention of acute graft-versus-host-disease (aGVHD). These data will be featured in an ePoster Flash Session oral presentation at the Congress of the European Society of
 Clinical Microbiology and Infectious Diseases (ESCMID Global), taking place in Vienna, Austria from April 11-15, 2025. Details on ePoster number E0145 can be found below. About the Phase 1b/2a Clinical Trial The ongoing randomized, double-blinded, placebo-controlled Phase 1b/2a clinical trial is being conducted at Washington University School of Medicine in St. Louis. The trial is designed to evaluate the safety, tolerability, and potential absorption of oral SYN-004 (150 mg q.i.d. for a maximum of 28 days) into the systemic circulation of allogeneic HCT recipients who receive an IV antibiotic to treat fever. To mitigate risk, Cohort 1 of the study administered meropenem as the study-assigned antibiotic. Meropenem is a carbapenem antibiotic that is not metabolized by SYN-004. Patients in Cohort 2 were administered piperacillin/tazobactam as the study-assigned antibiotic and patients in Cohort 3 will receive cefepime. Piperacillin and cefepime can be metabolized by SYN-004. The trial is also designed to evaluate potential protective effects of SYN-004 on the gut microbiome as well as generate preliminary information on potential therapeutic benefits and patient outcomes of SYN-004 in allogeneic HCT recipients. The trial is expected to enroll up to 36 participants with three sequential cohorts, each evaluating a different study-assigned IV beta-lactam antibiotic. Safety and pharmacokinetic data for each cohort is reviewed by an independent Data and Safety Monitoring Committee that makes a recommendation on whether to proceed to the next IV beta-lactam antibiotic. More information on the study is available here ( NCT04692181 ). About SYN-004 (ribaxamase) SYN-004 (ribaxamase) is an oral prophylactic therapy designed to degrade certain IV beta-lactam antibiotics within the GI tract and maintain the natural balance of the gut microbiome for the prevention of Clostridioides difficile infection (CDI), overgrowth of pathogenic organisms, the emergence of antimicrobial resistance (AMR) and acute graft-versus-host-disease (aGVHD) in allogeneic hematopoietic cell transplant (HCT) recipients. Allogeneic HCT recipients routinely receive long courses of IV beta-lactam antibiotics to treat infection following conditioning therapy. Antibiotic-mediated damage of the gut microbiome in allogeneic HCT recipients may lead to adverse outcomes including CDI, VRE colonization and potentially fatal bacteremia and aGVHD. A previously completed placebo-controlled Phase 2b clinical trial of 412 patients demonstrated SYN-004 protected the gut microbiome from antibiotic-mediated dysbiosis. Patients who received SYN-004 also demonstrated significantly better maintenance and recovery of the gut microbiome as well as lower incidences of new colonization by opportunistic and potentially pathogenic microorganisms such as VRE. About Theriva™ Biologics, Inc. Theriva™ Biologics (NYSE American: TOVX), is a diversified clinical-stage company developing therapeutics designed to treat cancer and related diseases in areas of high unmet need. The Company’s subsidiary Theriva Biologics, S.L. , has been developing a new oncolytic adenovirus platform designed for intravenous (IV), intravitreal and antitumoral delivery to trigger tumor cell death, improve access of co-administered cancer therapies to the tumor, and promote a robust and sustained anti-tumor response by the patient’s immune system. The Company’s lead clinical-stage candidates are: (1) VCN-01 (zabilugene almadenorepvec), an oncolytic adenovirus designed to replicate selectively and aggressively within tumor cells, and to degrade the tumor stroma barrier that serves as a significant physical and immunosuppressive barrier to cancer treatment; (2) SYN-004 (ribaxamase) which is designed to degrade certain commonly used IV beta-lactam antibiotics within the gastrointestinal (GI) tract to prevent microbiome damage, thereby limiting overgrowth of pathogenic organisms such as VRE (vancomycin resistant Enterococci) and reducing the incidence and severity of acute graft-versus-host-disease (aGVHD) in allogeneic hematopoietic cell transplant (HCT) recipients); and (3) SYN-020, a recombinant oral formulation of the enzyme intestinal alkaline phosphatase (IAP) produced under cGMP conditions and intended to treat both local GI and systemic diseases.
