IMV Inc. Announces Initial Data from the Ongoing Phase 2B VITALIZE Trial in Patients with r/r DLBCL
Complete responses were observed in patients who received at least three previous lines of treatment (including CAR-T's)
Recent clinical data add to the growing enthusiasm for the therapeutic potential of cancer vaccines in combination with checkpoint inhibitors
Oral presentation of the clinical data at the Immuno-Oncology 360° conference in February 2023
DARTMOUTH, Nova Scotia, & CAMBRIDGE, Mass.--(BUSINESS WIRE)-- IMV Inc. (Nasdaq: IMV; TSX: IMV) (“IMV” or the “Company”), a clinical-stage biopharmaceutical company developing a portfolio of immune-educating therapies based on its novel DPX® platform to treat solid and hematologic cancers, today announced positive initial patient data from the VITALIZE Phase 2B trial evaluating its lead DPX product, MVP-S, in combination with pembrolizumab in patients with relapsed, refractory Diffuse Large B Cell Lymphoma (“r/r DLBCL”) who received at least three previous lines of treatment. Detailed results will be presented in a podium presentation at the Immuno-Oncology 360° conference to be held in New York City on February 7-10, 2023.
“The initial clinical data from the VITALIZE trial are encouraging and the accelerating recruitment in this study reflects a growing interest for this therapeutic combination in DLBCL,” said Dr. Matthew Matasar, Chief of Blood Disorders at Rutgers Cancer Institute of New Jersey and RWJBarnabas Health, and primary investigator of the VITALIZE trial. He added: “We find it remarkable that we have seen complete responses in this trial in patients that were refractory to prior cellular therapy and other advanced therapies.”
“Positive initial results for the VITALIZE trial are an important development milestone for MVP-S” said Andrew Hall, CEO of IMV “Alongside other compelling cancer vaccine data announced this week, these data on MVP-S highlight renewed interest in the potential for cancer vaccines as a therapeutic class.”
Andrew Hall added “A well-tolerated, easy-to-administer therapy, such as MVP-S, that provides durable clinical benefit is meaningful for patients who have already been subject to aggressive, toxic treatment regimens. Clinical activity in a highly refractory patient population may represent a path to registration in DLBCL.”
About the VITALIZE Study
The VITALIZE Phase 2B trial is a randomized, parallel group, Simon two-stage study designed to assess IMV’s lead candidate, MVP-S, in combination with pembrolizumab with or without cyclophosphamide. Across the arms of this study, the combination will be evaluated in up to 102 subjects with r/r DLBCL who have received at least two prior lines of systemic therapy and who are ineligible or have failed autologous stem cell transplant (ASCT) or CAR-T therapy.
The primary endpoint is Objective Response Rate (ORR), centrally evaluated per Lugano (2014) and measured by the number of subjects per arm achieving a best clinical response of Partial or Complete Response (PR+CR) during the 2-year treatment period. All subjects will be evaluated for their baseline PD-L1 expression. Exploratory endpoints include evaluation of cell-mediated immune response, tumor immune cell infiltration, and other biomarker analyses.
