Enlivex Announces Dosing of the First Patient in Phase I/II Trial Evaluating Allocetra Alone and in Combination with a PD1 Checkpoint Inhibitor in Patients with Advanced Solid Tumors
- Multi-center trial of AllocetraTM in advanced solid tumor patients
- AllocetraTM is administered to the patients either intravenously or locally, depending upon tumor locations, as both monotherapy and in combination with anti-PD1
- Trial builds on encouraging preclinical studies conducted in collaboration with Yale Cancer Center that showed a substantial, statistically significant survival benefit when Allocetra™ was combined with a PD1 checkpoint inhibitor in a murine model of ovarian cancer, and additional models that demonstrated statistically significant survival benefit when Allocetra™ was combined with a PD1 or CTLA-4 checkpoint inhibitors in a murine model of peritoneal mesothelioma
Nes-Ziona, Israel, Nov. 15, 2022 (GLOBE NEWSWIRE) -- Enlivex Therapeutics Ltd. (Nasdaq: ENLV, the “Company”), a clinical-stage macrophage reprogramming immunotherapy company, today announced that the first patient has been dosed in a Phase I/II clinical trial designed to evaluate the safety, tolerability and preliminary efficacy of Allocetra™ alone, and in combination with a PD1 checkpoint inhibitor, in patients with advanced solid tumors.
Oren Hershkovitz, Ph.D., Chief Executive Officer of Enlivex, stated "Our team is continuing to focus on execution of our strategic and operating plan across our various clinical development verticals, with an ongoing sepsis Phase II clinical trial and two ongoing oncology Phase I/II clinical trials. We believe that AllocetraTM has the potential to provide a paradigm shift in treatment of advanced solid tumors, and we look forward to observing safety and potential indication of effect in patients, who we expect to enroll in our open-label oncology trials during 2023.
ABOUT THE PHASE I/II TRIAL
The Phase I/II trial is a multicenter, open-label, dose escalation trial that is expected to enroll up to 48 patients with advanced solid tumors across two trial stages. Stage 1 of the trial will examine escalating doses of Allocetra™ monotherapy administered intravenously (IV) or intraperitoneally (IP) once a week for three consecutive weeks. Stage 2 will evaluate escalating doses of Allocetra™ administered IV or IP and combined with anti-PD1 therapy. Patients in Stage 2 will receive three injections of Allocetra™ concomitantly with the studied anti-PD1 agent. The primary objective of the study is to evaluate safety and tolerability throughout the treatment period and through one week after the last administration of Allocetra™. Key secondary endpoints include efficacy assessments, such as best overall response rate, progression-free survival, and overall survival. Changes in immune cell/cytokine profiling in peritoneal fluid will also be assessed as an exploratory endpoint. The study population encompasses adult patients with advanced, unresectable or metastatic solid tumors that have relapsed or have been refractory to available approved therapies, or patients who are not eligible for, or have declined additional standard-of-care systemic therapy.
Allocetra™ is being developed as a universal, off-the-shelf cell therapy designed to reprogram macrophages into their homeostatic state. Diseases such as solid cancers, sepsis, and many others reprogram macrophages out of their homeostatic state. These non-homeostatic macrophages contribute significantly to the severity of the respective diseases. By restoring macrophage homeostasis, Allocetra™ has the potential to provide a novel immunotherapeutic mechanism of action for life-threatening clinical indications that are defined as "unmet medical needs", as a stand-alone therapy or in combination with leading therapeutic agents.
Enlivex is a clinical stage macrophage reprogramming immunotherapy company developing Allocetra™, a universal, off-the-shelf cell therapy designed to reprogram macrophages into their homeostatic state. Resetting non-homeostatic macrophages into their homeostatic state is critical for immune system rebalancing and resolution of life-threatening conditions.
