Trial will investigate AIVITA's platform cancer immunotherapy in combination with anti-PD-1 checkpoint inhibitors
IRVINE, Calif. /PRNewswire/ -- AIVITA Biomedical, Inc., a biotech company specializing in innovative stem cell applications, announced today the U.S. Food and Drug Administration (FDA) has cleared its Investigational New Drug (IND) application for a Phase 1B clinical trial investigating the Company's ROOT OF CANCER technology in patients with metastatic melanoma. The trial marks the first time AIVITA's cancer immunotherapy technology will be tested in combination with checkpoint inhibitors.
"As our non-responding patients all have elevated checkpoint levels, this combination therapy is a natural extension of our technology, and indeed, checkpoint inhibitors," said Dr. Robert O. Dillman, Chief Medical Officer at AIVITA. "Now that the limitations of anti-PD-1 therapy have been realized, many experts are touting the advantages of adding a personalized vaccine to an anti-PD-1 approach."
AIVITA's open-label, single-arm, phase 1B treatment study will establish the safety of administering anti-PD1 monoclonal antibodies in combination with AV-MEL-1 in patients with measurable metastatic melanoma. The study will also track efficacy of the treatment for the estimated 14 to 20 patients.
AIVITA's personalized patient-specific platform cancer technology uniquely and selectively targets the patient's tumor-initiating cells, which seed tumor growth, metastases and tumor recurrence. Previously, this treatment was tested in two Phase 2 trials in patients with advanced melanoma and approved for Phase 3 testing. These clinical studies demonstrated the efficacy of the approach in a randomized trial, yielding a 72% 2-year survival rate and a 54% 5-year survival rate.
AIVITA's ROOT OF CANCER technology is currently the subject of two ongoing multi-center Phase 2 trials in the USA, one in patients with a primary diagnosis of advanced ovarian cancer and another in patients with newly diagnosed glioblastoma. The Company is also applying to commercialize the treatment of melanoma patients in Japan and is considering Japanese strategic partners for this program, having just received an enabling approval of its manufacturing, quality systems and safety by Japan's PMDA.
About ROOT OF CANCER
AIVITA's treatment is a platform technology applicable to most solid tumor types and consists of autologous dendritic cells loaded with autologous tumor antigens from autologous self-renewing tumor-initiating cells.
AIVITA's ovarian Phase 2 double-blind study is active and enrolling approximately 99 patients who will be randomized in a 2:1 ratio to receive either the autologous dendritic cell vaccine or autologous monocytes as a comparator.
Patients eligible for randomization and treatment will be those (1) who have undergone debulking surgery, (2) for whom a cell line has been established, (3) who have undergone leukapheresis from which sufficient monocytes were obtained, (4) have an ECOG performance grade of 0 or 1 (Karnofsky score of 70-100%), and (5) who have completed primary therapy.

AIVITA's glioblastoma Phase 2 single-arm study is active and will enroll approximately 55 patients to receive the treatment candidate.
Patients eligible for treatment will be those (1) who have recovered from surgery such that they are about to begin concurrent chemotherapy and radiation therapy (CT/RT), (2) for whom an autologous tumor cell line has been established, (3) have a Karnofsky Performance Status of > 70 and (4) have undergone successful leukapheresis from which peripheral blood mononuclear cells (PBMC) were obtained that can be used to generate dendritic cells (DC).
