─On Track for Midyear 2024 Topline Data and Late 2024/Early 2025 Open Label Data Readouts from CM-101 Phase 2 Trial in Primary Sclerosing Cholangitis (PSC), Following Early Completion of Patient Enrollment Six Months Ahead of Schedule─

─New Peer-Reviewed Publications Based on Patient Sample Studies Further Reinforce the Key Role of Chemomab’s Novel CCL24 Target in Both PSC and Systemic Sclerosis─

─PSC Expert Webinar Highlights the Emerging Importance of Surrogate Biomarkers in PSC Clinical Development─

TEL AVIV, Israel, May 09, 2024 (GLOBE NEWSWIRE) -- Chemomab Therapeutics Ltd. (Nasdaq:CMMB), (Chemomab), a clinical-stage biotechnology company developing innovative therapeutics for fibro-inflammatory diseases with high unmet need, today announced financial and operating results for the first quarter ended March 31, 2024, and provided a corporate update.

“These are exciting times for Chemomab. We began the new year announcing early completion of enrollment in our CM-101 Phase 2 trial in patients with primary sclerosing cholangitis (PSC) six months ahead of schedule, allowing us to move up our topline readout to midyear 2024. This potentially transformative milestone for Chemomab will be followed by additional significant catalysts later this year or early in 2025, when we expect to report topline results from the 33-week open label extension of the PSC trial as well as feedback from the FDA on a possible Phase 3 trial design,” said Adi Mor, PhD, co-founder, Chief Executive Officer and Chief Scientific Officer of Chemomab. “These achievements reflect the superb work of our medical and clinical development teams and the support of our PSC investigators, along with the enthusiastic response of patients eager to help advance the quest for effective new treatments.”

Dr. Mor added, “In the first months of 2024, we also reported new peer reviewed publications further validating the role of our CCL24 target and our CCL24-neutralizing antibody CM-101 in both PSC and systemic sclerosis (SSc). Our CM-101 SSc program is Phase 2 ready with an open IND, and we look forward to initiating patient enrollment when resources permit. Our robust patent estate for CM-101 was reinforced with additional patents granted in the E.U., Brazil and Israel. In April, we hosted an expert PSC webinar that included informative updates on diagnosis and treatment, as well as emerging knowledge around the role of surrogate biomarkers and other noninvasive clinical endpoints in PSC management and clinical development. We look forward to building on these positive developments during what we expect to be an eventful remainder of the year.”

First Quarter 2024 and Recent Updates

• In April, 2024, Chemomab announced the publication of a new study in the journal Arthritis Care and Research that further confirms the key role of its novel target CCL24 in systemic sclerosis. The longitudinal study of a cohort of more than 200 SSc patients showed that CCL24 is associated with increased mortality and disease severity across the fibrotic and vascular manifestations of the disease.
• In April, 2024, Chemomab hosted a well-attended webinar on primary sclerosing cholangitis featuring Christopher Bowlus, MD, of UC Davis Health; Ricky Safer, founder and CEO of PSC Partners Seeking a Cure and Massimo Pinzani, MD, PhD, of the UCL Institute for Liver and Digestive Health and UPMC ISMETT. Topics included an overview of current PSC diagnosis and treatment, the emerging consensus around surrogate biomarkers and other noninvasive clinical endpoints and the role of patient advocacy groups in supporting advances in treatment.

• In March, 2024, Chemomab reported that the European Patent Office had granted a new patent for CM-101, Chemomab’s first-in-class monoclonal antibody, covering the use of CM-101 and sequence-related anti-CCL24 antibodies for the treatment of hepatic (liver) diseases, including PSC. In February, the company announced new patents were granted in Brazil and Israel. The Brazilian patent includes claims broadly covering CM-101 and related anti-CCL24 antibodies along with their use for the treatment of fibrotic, inflammatory and autoimmune diseases. The Israeli patent covers the use of CM-101 in the treatment of hepatic diseases, including PSC. These patents supplement the extensive protections afforded by CM-101 patents issued and allowed in the U.S. and other major territories.
• In January, 2024, Chemomab reported publication of new proteomics research in the peer-reviewed journal Cells reinforcing the clinical potential of CM-101 in primary sclerosing cholangitis. The proteomic analyses of human samples highlighted the unique role of CCL24 in activating key PSC-related disease mechanisms. These findings further confirm the potential of CM-101 as a promising therapy for PSC.
• In January, 2024, Chemomab announced early completion of patient enrollment in the CM-101 Phase 2 PSC SPRING trial and moved up the expected topline data readout to midyear 2024, rather than in the second half of 2024 as had been previously projected.
  

First Quarter 2024 Financial Highlights

• Cash Position: Cash, cash equivalents and short-term bank deposits were $16.0 million as of March 31, 2024, compared to $19.9 million as of December 31, 2023.
  

• Research and Development (R&D) Expenses: R&D expenses were $3.1 million for the first quarter of 2024, compared to $6.9 million for the first quarter of 2023. The decrease in R&D expenses in the first quarter of 2024 compared to the first quarter of 2023 primarily resulted from the early completion of patient enrollment in the company’s CM-101 Phase 2 PSC trial.
  

• General and Administrative (G&A) Expenses: G&A expenses were $0.9 million for the first quarter of 2024, compared to $2.2 million for the first quarter of 2023. The decrease in G&A expenses primarily reflected reductions in headcount, consulting fees and other cost savings.
  

• Net Loss: Net loss was $3.9 million, or a net loss of approximately $0.01 per basic and diluted ordinary share for the first quarter of 2024, compared to $8.8 million, or a net loss of approximately $0.04 per basic and diluted ordinary share for the first quarter of 2023. The weighted average number of ordinary shares outstanding, basic and diluted, was 284,151,752 (equal to approximately 14.2 million ADSs) for the first quarter of 2024.
  

• Liquidity and Capital Resources: Chemomab believes its existing liquidity resources as of March 31, 2024 will enable it to fund its operations through March 31, 2025.

About Chemomab Therapeutics Ltd.
Chemomab is a clinical stage biotechnology company developing innovative therapeutics for fibro-inflammatory diseases with high unmet need. Based on the unique and pivotal role of CCL24 in promoting fibrosis and inflammation, Chemomab developed CM-101, a monoclonal antibody that neutralizes CCL24 activity. In clinical and preclinical studies, CM-101 appears safe, with the potential to treat multiple severe and life-threatening fibro-inflammatory diseases. Chemomab has reported positive results from three clinical trials of CM-101 in patients, including a Phase 2a liver fibrosis trial in NASH patients and an investigator-initiated study in patients with severe lung injury. A Phase 2 trial in primary sclerosing cholangitis has completed patient enrollment, with topline data expected midyear 2024. Chemomab’s CM-101 program for the treatment of systemic sclerosis is Phase 2-ready with an open U.S. IND. For more information about Chemomab, visit chemomab.com.
