Reported Positive Phase 2 Results Demonstrating Safety and Anti-Fibrotic, Anti-Inflammatory and Anti-Cholestatic Activity across Multiple Components of Primary Sclerosing Cholangitis (PSC)

Establishes Clinical Proof-of-Concept for Disease-Modifying Potential of CM-101 and Provides Foundation for Advancing to PSC Phase 3 Pivotal Trial

Completed PIPE Financing Including Major New and Existing Investors that Extends Cash Runway Through Beginning of 2026

On Track to Achieve Key Clinical Milestones in First Quarter of  2025; Continuing Discussions with Potential Partners

TEL AVIV, Israel, August 21, 2024 -- 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 second quarter ended June 30, 2024, and provided a corporate update.                         

“This past period has been an exciting time of transformation for Chemomab. The positive results of the Phase 2 SPRING trial represent a major milestone for the company and clearly establish clinical proof-of-concept for CM-101 in primary sclerosing cholangitis (PSC) and potentially other fibrotic diseases,” said Adi Mor, PhD, co-founder, Chief Executive Officer and Chief Scientific Officer of Chemomab. “CM-101 achieved the primary and key secondary endpoints in the trial and is the first therapy to demonstrate broad, clinically relevant effects on the three main components of PSC. This is also the first PSC trial to show, after just 15 weeks of treatment, a statistically significant reduction in liver stiffness, a widely used and well validated measure for assessing disease progression in PSC.”

“We believe these results provide strong support for advancing CM-101 to a Phase 3 PSC trial, which we are in the process of planning and will be discussing with the FDA during the End-of-Phase 2 meeting targeted for later this year. We anticipate two milestones early in 2025 – additional data from the open label extension portion of the SPRING trial and finalization of the PSC Phase 3 design reflecting our discussions with the FDA. Based on recent developments in related indications, we are optimistic that an accelerated approval design incorporating surrogate biomarkers may be feasible for CM-101.”

Dr. Mor continued, “We were pleased to welcome existing and major new investors, including OrbiMed, HBM Partners and Sphera, who participated in our successful $10 million PIPE financing. The proceeds generated by this financing will enable us to achieve our upcoming milestones in early 2025 and fund the operations of the company through the beginning of 2026.”

Dr. Mor concluded, “As a first-in-class molecule with a promising novel target relevant to multiple fibro-inflammatory diseases, CM-101 has long been of interest to potential biopharma partners. As expected, the positive data reported from the Phase 2 SPRING trial provides us opportunities to further advance the optimal path forward for CM-101, including potentially partnering to accelerate timelines for CM-101 development in PSC and other indications.”

 Second Quarter 2024 and Recent Updates

• On July 30, 2024, Chemomab announced the closing of a private placement that resulted in gross proceeds of approximately $10 million. Existing investors such as OrbiMed and new investors including HBM Partners and Sphera Biotech Master Fund participated in the financing, which extends the company’s cash runway through early 2026.
   
• On July 25, 2024, Chemomab reported topline results from the CM-101 Phase 2 SPRING trial in patients with PSC. CM-101 met the primary study endpoint, demonstrating a favorable safety profile over the 15-week treatment period. CM-101-treated patients with moderate/advanced disease showed improvements on a wide range of disease-related secondary endpoints, including assessments of changes from baseline relative to placebo at Week 15 in liver stiffness; in liver fibrosis biomarkers, including the Enhanced Liver Fibrosis (ELF) score and PRO-C3 levels; in total bilirubin and liver function tests; in pruritis (itch) and in markers of inflammation. Dose-dependent responses were observed for multiple disease-related biomarkers. A consistent pattern of greater improvement on the secondary endpoints was observed in the study arm receiving the higher 20 mg/kg dose of CM-101 and in the prespecified subgroup of PSC patients with moderate/advanced disease. The open label extension portion of the Phase 2 SPRING trial is continuing, with results expected to be reported in early 2025.
   
• On June 18, 2024, Chemomab announced new scientific publications reinforcing the clinical potential of CM-101 in PSC. A proteomic analysis of patient samples further confirmed that the company’s novel CCL24 target is associated with disease severity and progression in PSC.
   
• On June 6, 2024, Chemomab participated in multiple data presentations at EASL 2024 and a Gordon Research Conference supporting the clinical potential of CM-101 as a novel treatment for PSC. The findings support CM-101’s mode of action in liver fibrosis and could help in characterizing its anti-fibrotic drug effects and potentially serve as a translational tool in future PSC clinical trials.
   
• On April 18, 2024, Chemomab announced a new peer-reviewed publication reinforcing the clinical association of its novel CCL24 target with disease severity and mortality in patients with systemic sclerosis.
   
• On April 10, 2024, Chemomab hosted an expert PSC webinar 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.

Second Quarter 2024 Financial Highlights

• Cash Position: Cash, cash equivalents and short-term bank deposits were $12.8 million as of June 30, 2024, compared to $19.9 million as of December 31, 2023. On July 30, 2024, Chemomab successfully closed a $10 million private investment.
   
• Research and Development (R&D) Expenses: R&D expenses were $2.9 million for the second quarter of 2024, compared to $5.0 million for the second quarter of 2023. The decrease in R&D expenses in the second quarter of 2024 compared to the second quarter of 2023 primarily resulted from the completion of the double-blinded portion of the company’s CM-101 Phase 2 PSC trial.
   
• General and Administrative (G&A) Expenses: G&A expenses were $0.8 million for the second quarter of 2024, compared to $3.2 million for the second 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 $3.6 million, or a net loss of approximately $0.01 per basic and diluted ordinary share for the second quarter of 2024, compared to $8.0 million, or a net loss of approximately $0.04 per basic and diluted ordinary share for the second quarter of 2023. The weighted average number of ordinary shares outstanding, basic and diluted, was 286,080,133 (equal to approximately 14.3 million ADSs) for the second quarter of 2024.
   
• Liquidity and Capital Resources: Chemomab believes its existing liquidity resources as of June 30, 2024, together with the additional funds of approximately $10 million raised in July 2024, will enable the Company to fund its operations through the beginning of 2026.
   
• Number of issued and outstanding shares:  Following completion of its July 2024 financing, the Company had 18,508,057 ADSs (representing 370,161,140  ordinary shares) issued and outstanding and 25,121,231 ADSs (representing 502,424,620  ordinary shares) outstanding on a fully diluted basis.

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 the soluble protein CCL24 in promoting fibrosis and inflammation, Chemomab developed CM-101, a monoclonal antibody that neutralizes CCL24 activity. In clinical and preclinical studies, CM-101 has been shown to have a favorable safety profile and has been generally well-tolerated to date, with the potential to treat multiple severe and life-threatening fibro-inflammatory diseases. Chemomab has reported positive results from four clinical trials of CM-101 in patients, including a Phase 2 trial in patients with primary sclerosing cholangitis (PSC), a Phase 2a liver fibrosis trial in patients with metabolic dysfunction-associated steatohepatitis (MASH), a Phase 1b study in patients with metabolic dysfunction–associated fatty liver disease (MAFLD) and an investigator-initiated study in patients with severe lung injury. Chemomab’s CM-101 program for the treatment of systemic sclerosis is Phase 2-ready with an open U.S. IND. For more information, visit www.chemomab.com.
