IRVINE, Calif., Aug. 14, 2019 /PRNewswire/ — AIVITA Biomedical, Inc., a biotech company specializing in innovative stem cell applications, announced today updated clinical data from its ongoing glioblastoma Phase 2 clinical trial, investigating AIVITA’s platform immunotherapy targeting tumor-initiating cells. Blood plasma biomarker analyses have identified a robust immune response and a decrease of tumor biomarkers in 65% of treated patients, in a sample that represents 29% of the total Phase 2 clinical trial size.
Blood was collected from subjects at multiple time points, one week after each dose administration, and assayed for 450 different immune and tumor biomarkers. Treatment elicited a robust immune response, with biomarkers suggesting progressive activation of dendritic cell cross-presentation and progressive activation of a type II hypersensitivity antibody-mediated cytotoxic response. Most notably, 65% of the treated glioblastoma patients also showed a robust decrease of 27 different biomarkers associated with tumor development, including markers of tumor-associated angiogenesis, tumor-associated growth factors, and tumors themselves.
“An objective tumor biomarker response, combined with a robust and appropriate immune response, suggests a decrease of tumor burden in 65% of our treated patients,” said Dr. Hans S. Keirstead, AIVITA’s Chief Executive Officer. “Should this translate to survival, it would represent a major step forward in our fight against glioblastoma.”
AIVITA is currently conducting three distinct clinical studies investigating its platform immunotherapy, in patients with ovarian cancer, glioblastoma and melanoma. AIVITA uses 100% of proceeds from the sale of its ROOT of SKIN™ skincare line to support the treatment of women with ovarian cancer.
CLINICAL TRIAL DETAIL
AIVITA’s ovarian Phase 2 double-blind study is active and enrolling approximately 99 patients who are being randomized in a 2:1 ratio to receive either the autologous tumor-initiating cell-targeting immunotherapy 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. The trial is not open to patients with recurrent ovarian cancer.

AIVITA’s glioblastoma Phase 2 single-arm study is active and is enrolling approximately 55 patients to receive the tumor-initiating cell-targeting immunotherapy.
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). The trial is not open to patients with recurrent glioblastoma.

AIVITA’s melanoma Phase 1B open-label, single-arm study will establish the safety of administering anti-PD1 monoclonal antibodies in combination with AIVITA’s tumor-initiating cell-targeting immunotherapy in patients with measurable metastatic melanoma. The study will also track efficacy of the treatment for the estimated 14 to 20 patients. This trial is not yet open for enrollment.
Patients eligible for treatment will be those (1) for whom a cell line has been established, (2) who have undergone leukapheresis from which sufficient monocytes were obtained, (3) have an ECOG performance grade of 0 or 1 (Karnofsky score of 70-100%), (4) who have either never received treatment for metastatic melanoma or were previously treated with enzymatic inhibitors of the BRAF/MEK pathway because of BRAF600E/K mutations and (5) are about to initiate anti-PD1 monotherapy.
