──FDA End-of-Phase 2 Meeting Scheduled in Fourth Quarter 2024 to Discuss the Design of a CM-101 Accelerated Approval Phase 3 Trial in Primary Sclerosing Cholangitis (PSC)──

──Cash Runway Extended to Early 2026; Continuing Discussions with Potential Strategic Partners; Preparations Underway to Advance CM-101 to Phase 3 in Late 2025──

TEL AVIV, Israel, November 14, 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 third quarter ended September 30, 2024, and provided a corporate update.

“These are exciting and transformational times for Chemomab,” said Adi Mor, PhD, co-founder, Chief Executive Officer and Chief Scientific Officer of Chemomab. "In the third quarter we reported the results of our CM-101 Phase 2 SPRING trial in patients with primary sclerosing cholangitis (PSC). The positive data from this trial represents a major clinical proof-of-concept for CM-101 as a potential disease-modifying treatment for PSC and other fibro-inflammatory diseases.” 

We are on track to complete two important milestones in the first quarter of 2025—first, agreement with the FDA on the design of a PSC pivotal trial for CM-101 and second, reporting new clinical data from the open label portion of the Phase 2 SPRING trial. We will be meeting with the FDA before the end of this year to discuss the design of a CM-101 registrational trial in patients with PSC. Based on recent developments, we are optimistic that our proposed design, which incorporates surrogate biomarkers as primary endpoints in a single pivotal study, will be accepted. This would be a significant development for Chemomab and for the PSC field. Importantly, in the Phase 2 SPRING trial, CM-101 demonstrated positive results across the surrogate biomarker endpoints under consideration, which may represent a significant de-risking as CM-101 advances into Phase 3. We look forward to sharing the outcome of these discussions with the FDA and the data from the open label portion of the SPRING trial in the first quarter of 2025.”

Dr. Mor added, “We currently are laying the groundwork for the PSC registrational trial, which we anticipate launching later in 2025. We continue to have active discussions with potential strategic partners, whose long-time interest in Chemomab and CM-101 has significantly ramped up since the release of our positive Phase 2 data. Our focus is on assessing options that would help accelerate the PSC clinical program, as well as our programs in systemic sclerosis and potentially other fibro-inflammatory diseases. Our goal is to maximize the value of our novel and unique asset for all our stakeholders and ensure that CM-101 is available to patients in need.”

Dr. Mor concluded, “We are excited that our Phase 2 SPRING trial data is the subject of a high profile late breaking oral presentation at the upcoming 2024 AASLD conference. Chemomab will be well-represented at this major scientific meeting, and we also will be available for meetings during the JP Morgan Healthcare Conference in San Francisco in January.”

Third Quarter 2024 and Recent Updates

• On October 15, 2024, Chemomab announced that on November 18, 2024, PSC expert Dr. Christopher Bowlus will be presenting a late-breaking oral presentation discussing the CM-101 PSC Phase 2 SPRING trial results at the AASLD The Liver Meeting® 2024.
   
• On July 30, 2024, Chemomab announced the closing of a private placement that resulted in gross proceeds of approximately $10 million to the company. Existing investors such as OrbiMed and new investors including HBM Partners and Sphera Biotech Master Fund participated in the financing. The financing extended the company’s runway through early 2026, after completion of the two major milestones expected in early 2025.
   
• 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 pruritus (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. The open label extension portion of the Phase 2 SPRING trial is continuing, with results expected to be reported in the first quarter of 2025.

Third Quarter 2024 Financial Highlights

• Cash Position and Liquidity:  Cash and short-term bank deposits were $19.5 million as of September 30, 2024, as compared to $12.8 million as of June 30, 2024 and $19.9 million as of December 31, 2023. During the third quarter of 2024 Chemomab completed a private placement that resulted in gross proceeds to the company of approximately $10 million. Chemomab believes its existing liquidity resources as of September 30, 2024, will enable the company to fund its operations through the beginning of 2026.
   
• Research and Development (R&D) Expenses: R&D expenses were $2.8 million for the third quarter of 2024, compared to $3.4 million for the third quarter of 2023. The decrease in R&D expenses in the third quarter of 2024 compared to the third quarter of 2023 primarily resulted from the completion of the double-blinded portion of the company’s CM-101 Phase 2 PSC trial in the third quarter of 2024.
   
• General and Administrative (G&A) Expenses: G&A expenses were $0.9 million for the third quarter of 2024, compared to $1.0 million for the  third quarter of 2023.
   
• Net Loss: Net loss was $3.5 million, or a net loss of approximately $0.01 per basic and diluted ordinary share for the third quarter of 2024, compared to $4.1 million, or a net loss of approximately $0.02 per basic and diluted ordinary share for the third quarter of 2023. The weighted average number of ordinary shares outstanding, basic and diluted, was 350,643,531 (equal to approximately 17.5 million ADSs) for the third quarter of 2024.
   
• Number of issued and outstanding shares: As of September 30, 2024, following completion of its July 2024 financing, the company had 18,856,611 ADSs (representing 377,132,220 ordinary shares) issued and outstanding and 25,469,786 ADSs (representing 509,395,720 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 role of the soluble protein CCL24 in promoting fibrosis and inflammation, Chemomab developed CM-101, a first-in-class dual activity monoclonal antibody that neutralizes CCL24 activity and has demonstrated disease-modifying potential. In clinical and preclinical studies, CM-101 has been shown to have a favorable safety profile and has been generally well-tolerated, 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. Based on recent promising data from its Phase 2 SPRING trial in the rare liver disease primary sclerosing cholangitis (PSC), the company expects two milestones in early 2025, including FDA feedback on the design of its planned CM-101 PSC Phase 3 registrational trial and data from the SPRING trial open label extension. CM-101 has received FDA and EMA Orphan Drug and FDA Fast Track designations for PSC. Chemomab’s CM-101 program for the treatment of systemic sclerosis is Phase 2-ready with an open U.S. IND.
