Clarametyx Biosciences Announces Positive Interim Analysis in Phase 2A Study Evaluating CMTX-101 for Infections Associated With Cystic Fibrosis
COLUMBUS, Ohio--(BUSINESS WIRE)-- Clarametyx Biosciences, Inc. ('Clarametyx'), a clinical-stage biotechnology company developing immune-enabling therapies and vaccines to address biofilm-driven chronic respiratory diseases, announced today that it is advancing a Phase 1b/2a clinical trial evaluating its novel immune-enabling antibody therapy CMTX-101 to treat cystic fibrosis (CF)-associated pulmonary infections, based on the DMC's approval to proceed following results of a pre-specified interim analysis.
'Interim findings from this study have identified encouraging trends that support the potential benefit of CMTX-101, with no safety issues,' said Jerry Nick, MD, Professor in the Division of Pulmonary, Critical Care and Sleep Medicine at National Jewish Health, and primary investigator of the study. 'The next portion of the trial will provide important insights on the potential therapeutic impact of CMTX-101 for the CF population as a novel solution to reduce the burden of chronic infections.'
The ongoing randomized, double-blind, placebo-controlled clinical trial is assessing CMTX-101 as an adjunctive therapy to standard of care antibiotics in people with CF, evaluating safety and tolerability, pharmacokinetics, immunogenicity, reduction of pulmonary Pseudomonas aeruginosa burden, and additional exploratory endpoints. An interim analysis of data from the first 21 participants enrolled met the pre-specified criteria to continue the trial at both 5 and 30 mg/kg dose levels. Participants treated with CMTX-101 demonstrated a reduction in P. aeruginosa burden based on prespecified statistical criteria and CMTX-101 was shown to be present in the sputum of all treated participants. Importantly, CMTX-101 was generally well tolerated, consistent with the findings reported in a prior clinical study, and no antidrug antibodies were detected.
The upcoming portion of the study will continue evaluating both doses of CMTX-101 versus placebo among approximately 20 additional participants from 23 study sites, including significant support from the Cystic Fibrosis Therapeutics Development Network. Study enrollment is expected to be complete by the end of 2025. More information on the study and participating sites is available at ClinicalTrials.gov (http://www.clinicaltrials.gov/) using the identifier NCT06159725.
'We are pleased that the findings from the first 21 participants enrolled support progressing the study without modification. The full dataset, which will include exploratory endpoints such as respiratory function, inflammatory biomarkers and quality of life assessments, will help us further understand the full potential of CMTX-101 as a novel therapeutic solution to a variety of chronic respiratory conditions,' said David V. Richards, Chief Executive Officer, Clarametyx. 'We extend our gratitude to the Cystic Fibrosis Therapeutics Development Network, clinical investigators, and the participants and families for their continued participation in this important research.'
About CMTX-101
CMTX-101 is an investigational immune-enabling antibody therapy in development to treat chronic and recalcitrant respiratory infections. The therapy is designed to precisely and rapidly destroy the universal underlying structure of bacterial biofilms to undermine extracellular bacterial defenses and enable more effective antibiotic and immune intervention. Because the target is universally present across bacteria, the approach can be employed to treat a range of bacterial infections and pathogen types. The goal of treatment is to dramatically improve the effectiveness of antibiotic therapies and innate immune system effectors, improving the time to resolution of the infection and reducing the need for repeated courses of antibiotics. It is currently in development to treat cystic fibrosis-associated infections, with opportunities to expand to other chronic respiratory infections including nontuberculous mycobacterial (NTM) lung disease, non-CF bronchiectasis (NCFB), and chronic obstructive pulmonary disease (COPD).
About Clarametyx Biosciences
Clarametyx Biosciences is combating the formidable challenge of chronic, recalcitrant respiratory infections through an innovative technology platform targeting the biofilm—a protective layer around bacteria—to enable a more effective immune response and antibiotic intervention. The Columbus, Ohio-based company is building a pipeline of immune-enabling therapies and vaccines, including CMTX-101, which is in a Phase 2 study for infections associated with cystic fibrosis, and CMTX-301, which is in early development.

OrsoBio to Present Preclinical Data on Mitochondrial Protonophore Portfolio in Models of Obesity at the American Diabetes Association's 85th Scientific Sessions
MENLO PARK, Calif.--(BUSINESS WIRE)--OrsoBio, Inc. ('OrsoBio' or 'the Company'), a clinical-stage biopharmaceutical company developing treatments for obesity and obesity-associated disorders, today announced new preclinical data being presented at the 85th Scientific Sessions of the American Diabetes Association (ADA) being held June 20-23, 2025, in Chicago, Ill. The Company will present three abstracts highlighting the efficacy of its mitochondrial protonophores to induce weight loss and provide glycemic benefits while preserving lean mass in diet-induced obese (DIO) mice. The studies demonstrate the potential of TLC-6740 and TLC-1180—as monotherapy and in combination with the glucagon-like peptide-1 (GLP-1) receptor agonist semaglutide—for both the induction and maintenance of weight loss following incretin treatment. 'The mechanism of our mitochondrial protonophores to increase energy expenditure complements that of incretins to enhance and sustain weight loss and provide additive metabolic benefits,' said Mani Subramanian, MD, PhD, Chief Executive Officer of OrsoBio. 'These preclinical findings mark an important step in fulfilling our mission to develop innovative, effective, oral therapies for obesity that preserve muscle and support cardiometabolic health.' OrsoBio is advancing a pipeline of novel therapies targeting obesity through mechanistically distinct and complementary approaches. The Company's lead candidates include TLC-6740 and TLC-1180, both mitochondrial protonophores that promote weight loss by increasing energy expenditure. In addition, OrsoBio is developing TLC-3595, a selective inhibitor of acetyl-CoA carboxylase 2 (ACC2), designed to enhance fat oxidation. "GLP-1 receptor agonists have transformed obesity treatment but are limited by gastrointestinal side effects and loss of muscle mass,' said Rob Myers, MD, Chief Medical Officer of OrsoBio. 'Our preclinical data show that our mitochondrial protonophores drive sustained, fat-selective weight loss and metabolic benefits when combined with or sequenced after GLP-1 receptor agonists. These findings support our ongoing Phase 1b study of TLC-6740 in combination with tirzepatide (NCT05822544)." Poster information: Sequential Combination of the Mitochondrial Protonophore TLC-6740 With Semaglutide Normalizes Body Weight and Preserves Lean Mass in DIO Mice Abstract #1687-P Poster Session: Monday, June 23, 2025 (12:30 - 1:30 p.m. CT) This preclinical study assessed TLC-6740 alone, in combination with low-dose semaglutide (sequential combination), and as maintenance therapy following semaglutide discontinuation in DIO mice. The sequential combination of TLC-6740 with low-dose semaglutide produced superior body weight and fat mass loss, and improved glycemic parameters compared with TLC-6740 alone and high-dose semaglutide. Initiating TLC-6740 after semaglutide discontinuation maintained body weight and fat mass loss, and glycemic benefits. These findings support evaluation of TLC-6740 in combination with incretins in people living with obesity; a 24-week combination study of TLC-6740 with tirzepatide is ongoing (NCT05822544). De Novo or Sequential Combination of the Mitochondrial Protonophore TLC-1180 With Semaglutide Improves Weight Loss and Preserves Lean Mass in DIO Mice Abstract #1694-P Poster Session: Monday, June 23, 2025 (12:30 - 1:30 p.m. CT) This preclinical study evaluated the effects of TLC-1180 alone, in combination with semaglutide, and as a maintenance treatment following semaglutide discontinuation in DIO mice. As monotherapy, TLC-1180 demonstrated body weight and fat mass loss and preserved lean mass. Body weight and fat mass loss were amplified, and lean mass was preserved with TLC-1180 in combination with semaglutide. These benefits persisted when TLC-1180 was used as a maintenance treatment after semaglutide discontinuation. These data highlight the potential of TLC-1180 as monotherapy, in combination with incretins, or as maintenance therapy post incretin discontinuation in people living with obesity. Novel Combination of a Mitochondrial Protonophore and an Acetyl-CoA Carboxylase 2 (ACC2) Inhibitor Causes Weight Loss and Preserves Lean Mass in Obese Mice Abstract #1686-P Poster Session: Monday, June 23, 2025 (12:30 - 1:30 p.m. CT) This preclinical study evaluated the effects of the mitochondrial protonophore, TLC-1180, and the ACC2 inhibitor, TLC-3595—as monotherapy and in combination—and semaglutide in DIO mice. TLC-3595 dose dependently reduced body weight, fat mass, and liver biochemistry while preserving lean mass in DIO mice. A combination of TLC-3595 with TLC-1180 had similar weight loss efficacy to semaglutide, but preserved lean mass. Taken together, these data suggest that the novel, all-oral, non-incretin combination of TLC-3595 and TLC-1180 may cause similar weight loss to incretins and may afford additional advantages, including improved weight loss quality and/or tolerability (e.g., reduced incidence of gastrointestinal adverse events). About TLC-6740 TLC-6740 is a novel, oral, liver-targeted mitochondrial protonophore in development for the treatment of obesity and obesity-associated diseases, including diabetes and MASH. Based on active hepatic uptake and mitochondrial protonophore activity, TLC-6740 increases energy expenditure in hepatocytes, and is expected to have broad, systemic metabolic and cardiovascular benefits, including weight loss, improved insulin sensitivity, and as a treatment for MASH, and dyslipidemia. TLC-6740 is currently being evaluated in a Phase 1b clinical trial, as monotherapy and in combination with tirzepatide, in patients living with obesity (NCT05822544). About TLC-1180 TLC-1180 is a novel, potent, long-acting mitochondrial protonophore that has been shown to increase energy expenditure in mice with diet-induced obesity (DIO). In preclinical studies of DIO mice, TLC-1180 induced weight loss, improved glucose control, and enhanced the efficacy of GLP-1 receptor agonists, both as a single agent and in combination with incretins. TLC-1180 is currently completing IND-enabling studies and a first-in-human study is expected to initiate in 2025. About TLC-3595 TLC-3595 is a novel and selective ACC2 inhibitor designed to treat obesity and type 2 diabetes by increasing fatty acid oxidation (FAO), reducing ectopic lipid accumulation, and improving insulin sensitivity in skeletal muscle and liver. The compound may also have potential as a treatment for other conditions characterized by impaired FAO, including heart failure with preserved ejection fraction (HFpEF) and metabolic dysfunction-associated steatohepatitis (MASH). About OrsoBio, Inc. OrsoBio, Inc. is a privately held, clinical-stage biopharmaceutical company dedicated to developing therapies to treat obesity and obesity-associated disorders, including type 2 diabetes, MASH, and severe dyslipidemias.
