Clarametyx Biosciences Reports Progress on CMTX-101 Antibody Therapy Study for Cystic Fibrosis Infections

Clarametyx Biosciences, Inc., a biotechnology firm based in Columbus, Ohio, has announced the completion of the Phase 1b portion of its clinical trial for CMTX-101, an innovative antibody therapy aimed at treating pulmonary infections linked with cystic fibrosis (CF). The company is now progressing to the Phase 2a portion of the trial.

The study's primary investigator, Dr. Jerry Nick, a professor at the National Jewish Health Department of Medicine, emphasized the susceptibility of the CF population to recurrent and chronic lung infections. He highlighted the initial Phase 1b data, which indicated no safety issues with CMTX-101. If the therapy is clinically validated to disrupt bacterial defenses and enhance responses to antibiotics and natural immunity, it could present a novel treatment strategy for CF patients.

This clinical trial is double-blind, randomized, and placebo-controlled. It aims to assess the safety and tolerability, pharmacokinetics (PK), immunogenicity, reduction of pulmonary P. aeruginosa burden, and other exploratory endpoints of CMTX-101 when used alongside standard antibiotics in CF patients. Following a review by independent safety committees, the Phase 2a segment will involve up to 41 CF-diagnosed adults to further evaluate the safety and tolerability of CMTX-101. Initial findings from this phase are expected in 2025.

Clarametyx Biosciences aims to tackle stubborn and chronic infections caused by various bacterial pathogens. The company's recent early-stage clinical study of CMTX-101 in community-acquired bacterial pneumonia provided valuable data on safety, tolerability, pharmacokinetics, and immunogenicity, along with preliminary efficacy insights. The study revealed no significant safety concerns and minimal anti-drug antibodies. Clarametyx will present positive topline findings from this study at IDWeek in Los Angeles.

David Richards, Chief Executive Officer of Clarametyx, acknowledged the significant challenge recurrent infections pose for CF patients and their families. He expressed optimism about the potential of their technology to redefine treatment strategies for chronic infections. With promising early data from the Phase 1b segment, the company is eager to move forward with the next phase to demonstrate the efficacy of their approach.

CMTX-101 is an antibody therapy designed to target and dismantle the universal structure of bacterial biofilms. This action disrupts extracellular bacterial defenses, enabling more effective antibiotic and immune interventions. As the target structure is universally present across various bacteria, CMTX-101 can potentially be used to treat multiple bacterial infections. The therapy is intended to be administered alongside a broad spectrum of standard antibiotics targeting both Gram-negative and Gram-positive bacteria. The goal is to enhance the effectiveness of antibiotic treatments and the body's immune response, reducing the duration of infections and the need for repeated antibiotic courses.

Clarametyx Biosciences focuses on developing therapies and vaccines that enable a more effective immune response and antibiotic intervention against life-threatening bacterial infections associated with biofilms. The company is building a pipeline of treatments, particularly targeting challenging respiratory infections, to combat persistent and difficult-to-treat bacterial pathogens.
