TEL AVIV, Israel, Aug. 14, 2023 /PRNewswire/ -- Chemomab Therapeutics Ltd. (Nasdaq: CMMB), (Chemomab), a clinical stage biotechnology company developing innovative therapeutics to treat rare fibro-inflammatory diseases with high unmet need, today announced financial and operating results for the second quarter ended June 30, 2023, and provided a corporate update.

"I am pleased to report that the company continued to make good progress during the  second quarter," said Adi Mor, PhD, co-founder, Chief Executive Officer and Chief Scientific Officer of Chemomab. "In June, the Board of Directors re-appointed me to the CEO position and re-appointed then Vice President of Finance Sigal Fattal as Chief Financial Officer. Our extensive prior experience in these roles and ongoing active involvement in company management have made for a seamless transition."

Dr. Mor continued, "During the quarter we sharpened our corporate strategy. We extended our cash runway to take us through the end of 2024 and the readout of topline results from our Phase 2 trial of CM-101 in patients with primary sclerosing cholangitis (PSC), expected in the second half of 2024. Extension of the cash runway was achieved by tightening our focus and selectively pruning expenses. Enrollment in the PSC trial continues to go very well and we are pleased to have the resources on-board to take us through this major milestone. In addition, we are increasingly optimistic about the potential prospects for the PSC program based on additional positive biomarker data from our Phase 2 liver fibrosis trial that may also be applicable to PSC. As part of our strategic refresh, we suspended the planned start of our Phase 2 systemic sclerosis (SSc) trial; however, we remain enthusiastic that CM-101 may have disease-modifying potential in this poorly-treated condition and the SSc program remains fully Phase 2-ready."

Dr. Mor added, "The second quarter was notable for our many scientific presentations at important European medical meetings like EASL and EULAR. We also published a research article in a respected peer-reviewed journal, JCI Insight. As a group, the studies reinforce our extensive data highlighting the central role of CCL24 in the pathophysiology of fibro-inflammatory diseases and confirm that our CCL24-neutralizing antibody, CM-101, has potential therapeutic utility in these conditions."

"Promising new data from secondary analyses of our Phase 2 liver fibrosis trial in NASH patients was presented in a late-breaking poster at the 2023 EASL Congress in July. The new results show encouraging improvements in additional inflammatory and fibrogenesis-related biomarkers. Overall, the improvements in biomarkers seen in the Phase 2 liver fibrosis trial reinforce our belief that these data may serve as a potential bridge to other anti-fibrotic indications such as PSC, providing additional evidence that CM-101 could be a valuable therapy for this potentially fatal disease that lacks effective treatment options."

Corporate Developments

Implemented Executive Changes
In June, Chemomab announced that Adi Mor, PhD, co-founder and former Chief Executive Officer (CEO), and then Director and Chief Scientific Officer, had been reappointed to the role of CEO, replacing Dale Pfost, PhD. Sigal Fattal, former Chief Financial Officer (CFO) and then Vice President, Finance, had been reappointed to the role of CFO, replacing Donald Marvin. Nissim Darvish, MD, PhD, was appointed Chairman of the Board, replacing Dr. Pfost. All the appointments were effective June 1, 2023. The company also announced that it was implementing additional cost-reduction measures that extend its cash runway from mid-year 2024 to the end of 2024, after the expected topline data readout from the Phase 2 CM-101 PSC trial.

Presented Data at 2023 EASL Biliary Conference Reinforcing the Proinflammatory Role of CCL24 in Cholestatic Disease
In a poster presentation at the 2023 EASL Biliary Conference in May, researchers used patient proteomic and animal data to demonstrate the proinflammatory role of CCL24 in cholestatic disease. In these studies, CM-101 demonstrated an anti-inflammatory effect by interfering with the migration of monocytes and neutrophils to the damaged biliary area in a PSC animal model, thereby reducing fibrosis and biliary hyperplasia.

Presented Patient Data at 2023 EULAR Congress Showing that Serum CCL24 Levels Can Predict Vascular and Fibrotic Complications of Systemic Sclerosis
In a poster presentation at the 2023 EULAR European Congress of Rheumatology in June, researchers presented results from a patient sample study demonstrating that high serum levels of CCL24 were correlated with SSc severity, including a higher incidence of fibrosis-associated symptoms; a three-fold increased risk of interstitial lung disease progression; and a shorter SSc-related 5-year survival time.

Reported Secondary Analyses of CM-101 Phase 2 Liver Fibrosis Trial
In a late-breaking poster presentation at the 2023 EASL Congress in July, Chemomab reported secondary analysis data from its Phase 2a liver fibrosis trial of CM-101 in patients with non-alcoholic steatohepatitis (NASH). The data showed improvements across an additional set of inflammatory and fibrotic biomarkers that are consistent with the positive topline clinical results Chemomab released in January. Additionally, in NASH patients at greater risk of disease progression, CM-101 treatment resulted in a greater biomarker response than in patients with lower risk disease or in placebo-treated patients. 

Reported Data Reinforcing the Clinical Potential of CM-101 as a Novel Treatment for PSC
At the 2023 EASL Congress in July, Chemomab presented two posters discussing the potential of CM-101 as a novel treatment for PSC. One of the posters reported on a new proteomic study demonstrating a direct relationship between the pro-inflammatory, pro-fibrotic activity of CCL24 and PSC disease-related pathways. The other poster described the clinical design of Chemomab's double-blind, placebo-controlled, multiple dose Phase 2 trial of CM-101 in PSC patients.

Published Peer-Reviewed Research Article Demonstrating the Key Role of CCL24 in PSC
This peer-reviewed research article published in the June issue of JCI Insight was produced through collaborations with prominent academic groups and supports the key role of CCL24 in driving the self-perpetuating fibrosis and inflammation that result in the severe liver damage characterizing PSC.
