Minerva Biotechnologies Announces FDA Acceptance of IND Application for huMNC2-CAR44 T cells to Treat Metastatic Breast Cancer

On June 24, 2019 Minerva Biotechnologies, a biopharmaceutical company focused on developing immunotherapies for cancer and cellular therapies in regenerative medicine, reported that the U.S. FDA (Food and Drug Administration) has approved their IND (Investigational New Drug) application to conduct clinical trials with huMNC2-CAR44, an autologous CAR T cell therapy for solid tumors (Press release, Minerva Biotechnologies, JUN 24, 2019, View Source [SID1234537234]). huMNC2-CAR44 targets MUC1* (muk one star), a cleaved form of MUC1 present on over 75% of solid tumor cancer cells. Unlike the normal full-length MUC1, MUC1* is a potent growth factor receptor that is rendered constitutively active when onco-embryonic growth factor NME7AB binds to and dimerizes its truncated extracellular domain.

Minerva intends to commence clinical trials in breast cancer before the end of 2019. "We are delighted that we will soon be able to begin human clinical trials for metastatic breast cancer," said Minerva CEO Dr. Cynthia Bamdad. "Over 95% of breast cancers are positive for MUC1*, and this cancer immunotherapy has the potential to bring hope to the many thousands of patients battling this terrible disease."

Minerva’s chimeric antigen receptor (CAR) technology genetically engineers the patient’s own immune cells to recognize and kill specific types of cancer cells. The homing device on the CAR is an antibody that can distinguish the tumor-associated cleavage product, MUC1*, from the normal, full-length MUC1. Previous attempts to make cancer therapeutics that target MUC1 have failed, we believe, because they have targeted the a portion of full-length MUC1, which on tumor cells is cleaved, then shed and released form the cancer cell surface. Minerva has an extensive patent portfolio covering the part of MUC1 that remains on cancer cells (MUC1*) which is a powerful growth factor receptor, its activating ligands, and next generation CAR T technology.

About the Drug Response Predictor – DRP Companion Diagnostic
Oncology Venture uses its multi gene DRP to select those patients who by the genetic signature of their cancer are found to have a high likelihood of responding to the drug. The goal is developing the drug for the right patients, and by screening patients before treatment the response rate can be significantly increased. The DRP method builds on the comparison of sensitive vs. resistant human cancer cell lines, including genomic information from cell lines combined with clinical tumor biology and clinical correlates in a systems biology network. DRP is based on messenger RNA from the patient’s biopsies.
DRP has proven its ability to provide a statistically significant prediction of the clinical outcome from drug treatment in cancer patients in 29 out of 37 clinical studies that were examined and is currently demonstrating promising results in an ongoing phase 2 study prospectively using LiPlaCis and its DRP to track, match and treat patients with metastatic breast cancer.
The DRP platform, i.e. the DRP and the PRP tools, can be used in all cancer types and is patented for more than 70 anti-cancer drugs in the US. The PRP is used by Oncology Venture for Personalized Medicine. The DRP is used by Oncology Venture for drug development.

Programmed death-ligand 1 (PD-L1) is a transmembrane protein that plays a major role in suppressing the immune system in many cancer patients. The binding of PD-L1 to the inhibitory checkpoint molecule PD-1 establishes an inhibitory signal that reduces the proliferation of antigen-specific T-cells while also reducing apoptosis in suppressive regulatory T cells (Tregs) that further inhibits immune responses.

NantKwest’s PD-L1 t-haNK cell therapy is a novel, NK cell-based immuno-oncology therapy that includes a PD-L1 based Chimeric Antigen Receptor (CAR) engineered into the company’s proprietary haNK NK cell, which also includes the high affinity variant of the CD16 receptor (V158 FcγRIIIa) to mediate antibody dependent cellular cytotoxicity (ADCC). Together, the use of this targeted, bi-specific, next generation PD-L1 t-haNK therapy has been shown in preclinical studies to significantly enhance cancer cell killing and improve overall response rates.

"In just a few short weeks since announcing the FDA clearance of our first bi-specific, engineered NK cell therapy clinical trial using a CD19 t-haNK targeting patients in lymphoma, we are now pleased to announce that the FDA has authorized the company to go forward with our second bi-specific NK cell therapy clinical trial using a PD-L1 t-haNK targeting patients with solid tumors," commented Dr. Patrick Soon-Shiong, Chairman and CEO of NantKwest. Dr. Soon-Shiong continued, "We plan to synergistically combine a wide range of immunotherapy molecules with our proprietary, multi-targeted, off-the-shelf NK cell therapy, in this case, a PD-L1 t-haNK to explore the unique therapeutic potential of integrating both the innate and adaptive immune systems to achieve durable complete remissions. Based on the FDA clearance, we look to rapidly transition this program to a Phase I human clinical trial designed to assess the safety, tolerability and efficacy of PD-L1 t-haNK cell therapy in patients with solid tumors. Upon completion of this safety phase, NantKwest intends to combine this PD-L1 t-haNK cell therapy with other immunomodulatory agents including NabFc-N803, a IL15 cytokine super agonist and Adenovirus/ yeast vectors delivering tumor associated and neoantigens, as part of an integrative, combination therapy designed to further enhance the therapeutic effectiveness of this novel NK cell-based therapeutic intervention, which we describe as our NANT Cancer Memory Vaccine."

PD-L1 t-haNK

NantKwest’s PD-L1 t-haNK cell therapy is designed to provide precise tumor-cell specificity through the use of a CAR construct that utilizes a PD-L1-specific scFv (single chain antibody fragment) engineered into the company’s proprietary haNK NK cell that includes the high affinity variant of the CD16 receptor (V158 FcγRIIIa) to mediate antibody dependent cellular cytotoxicity (ADCC). In preclinical studies, cytotoxicity of these GMP-grade, cryopreserved PD-L1 t-haNK cells were comprehensively evaluated against a panel of cancer cell lines with different levels of PD-L1 expression in vitro and in vivo, with these studies showing increased activity and selective cytotoxicity toward a wide range of PD-L1-expressing tumor cells.

To better inform routine patient care, these clinical trials will incorporate a state-of-the-art, biomarker analysis, including GPS Cancer, which is an integrated, multi-omics, whole genome, transcriptomic platform, provided by NantHealth, an affiliated company. These comprehensive molecular analysis tools are designed to provide critical information to the clinical study team regarding the unique molecular alterations associated with the patient’s cancer and response rates, potentially enhancing patient management.
