Biomica Presents Positive Clinical Data Update from Ongoing Phase 1 Trial of Microbiome-Based Therapeutic, BMC128, for Refractory RCC, NSCLC & Melanoma

24 May 2024, Israel: Biomica Ltd., a clinical-stage biopharmaceutical company developing innovative microbiome-based therapeutics and a subsidiary of Evogene Ltd. (Nasdaq: EVGN, TASE: EVGN), today announced encouraging initial findings from an ongoing Phase 1 clinical trial. In the study, Biomica is investigating the safety and tolerability of its microbiome-based immuno-oncology candidate, BMC128, in combination with nivolumab, an anti-PD1 immune checkpoint inhibitor, in patients with non-small cell lung cancer (NSCLC), melanoma, or renal cell carcinoma (RCC).

All trial participants, 11 patients, had experienced disease progression in prior immunotherapy treatment before joining the trial. These preliminary findings represent some of the initial positive evidence emerging from the burgeoning field of clinical research on cancer therapies leveraging gut microbiota. While these results are preliminary and subject to further validation, they suggest potential benefits for patients facing advanced stages of these malignancies.

ASCO 2024 Presentation Details:

Title: Preliminary results from a First-in-Human (FIH), open-label Phase 1 study with BMC128, a rationally designed live bacterial consortium, in combination with nivolumab.
Session Type: Poster Session
Abstract Number: 8631
Date and Time: June 3, 2024, 1:30 PM – 4:30 PM (CDT)

Key observations from the study include:

● Safety Profile: As of the data cutoff date, the safety profile of BMC128 has been exceptional, with no major safety events potentially associated with BMC128 reported during the course of BMC128 monotherapy or combination treatment, indicating a favorable safety profile for the investigational therapy.
● Clinical Responses: As of the data cutoff date, among the patients included in the study, 72% of refractory cases exhibited positive clinical signals, indicating a potential efficacy for the BMC128 and nivolumab combination.
● Response Rates: As of the data cutoff date, one patient demonstrated partial response (PR) upon imaging and RECIST v1.1 assessment and remains actively responding to treatment. Additionally, 64% of patients’ disease stopped progressing following the combination treatment, and they displayed stable disease (SD) and sustained benefits beyond the first imaging assessment, suggesting additional important potential clinical benefit.
● Durability of Response: As of the data cutoff date, 55% of patients showed sustained clinical benefit, with notable durations of response of over 16 weeks and with one patient exceeding 80 weeks.
● Cross-Cancer Effectiveness: 100% of RCC patients and 60% of NSCLC patients in the study demonstrated positive clinical outcomes, indicating potential efficacy across different cancer types.

With these encouraging early results, it is important to note that the study remains ongoing. Further data will become available and analyzed through the next few months to gain a deeper understanding of the therapeutic potential of BMC128 in combination with nivolumab in cancer treatment.

Prof. Gal Markel, Director of the Davidoff Cancer Center, Rabin Medical Center and Biomica’s Scientific Advisory Board member, said: “The positive trends emerging from the ongoing Phase 1 trial of BMC128, particularly in combination with nivolumab, underscore the transformative potential of microbiome-based therapeutics in oncology. These findings bring hope to patients contending with refractory RCC, NSCLC, and melanoma, envisioning a future where innovative treatments like BMC128 could provide meaningful solutions to longstanding challenges in cancer care. Additionally, the observed cross-cancer effectiveness hints at BMC128’s broad applicability across different cancer types, further solidifying its significance in the field of oncology. The demonstrated safety profile thus far, alongside the encouraging clinical benefits including response rate and notable durability, accentuates the potential efficacy of BMC128 in addressing the unmet needs of patients grappling with these malignancies. These initial results mark a significant advancement, reflecting our steadfast commitment to pioneering innovative solutions that address critical unmet needs in oncology.”

Dr. Elran Haber, Biomica CEO, stated, “The preliminary results from this Phase 1 study show positive evidence of BMC128’s superior safety profile and potential efficacy when combined with anti-PD1 checkpoint inhibitor immunotherapy. This suggests potential benefits for patients with refractory NSCLC, melanoma, or RCC who have not responded to, or developed resistance to previous immunotherapy treatments. We believe BMC128 has the promise to be a potential therapy for patients fighting cancer, and we look forward to continuing to evaluate BMC128’s beneficial activity in subsequent phases of clinical development. Furthermore, these results underscore the strength of Biomica’s computational platform for microbiome drug discovery, developed with Evogene, validating our approach to innovative therapeutic solutions.”
