Global Coalition for Adaptive Research, Biohaven, and Vigeo Announce Commencement of Biohaven’s Troriluzole and Vigeo’s VT1021 in GBM Agile Trial

Biohaven and Vigeo Now Enrolling in GBM Agile, Registrational Phase 2-3 Adaptive Platform Trial to Evaluate Interventions for Patients with Glioblastoma

LARKSPUR – Global Coalition for Adaptive Research (LARKSPUR, CA), Biohaven Pharmaceutical Holding Company Ltd. (NYSE: BHVN), and Vigeo Therapeutics – The Global Coalition for Adaptive Research (GCAR) in collaboration with Biohaven and Vigeo Therapeutics, today announced the activation of Biohaven’s troriluzole and Vigeo’s VT1021 in GBM AGILE (Glioblastoma Adaptive Global Innovative Learning Environment). GBM AGILE is a revolutionary patient-centered, adaptive platform trial for registration that tests multiple therapies for patients with newly-diagnosed and recurrent glioblastoma (GBM) – the deadliest form of brain cancer.

Biohaven’s troriluzole and Vigeo’s VT1021 are entering the GBM AGILE trial, which initially opened in July 2019 and has screened over 1200 patients to date. Troriluzole and VT1021 will enroll patients with newly-diagnosed and recurrent glioblastoma.

Dr. Michael Lim, Chair of the Department of Neurosurgery at Stanford University and Dr. Michael Weller, Director Department of Neurology, University Hospital Zurich, Switzerland will serve as arm Principal Investigators for troriluzole’s evaluation in GBM AGILE. VT1021 will be led by arm Principal Investigators, Dr. Howard Colman, Professor, Huntsman Cancer Institute and Department of Neurosurgery, University of Utah, and Dr. Tom Mikkelsen, Medical Director, Precision Medicine Program & Clinical Trials Office, Henry Ford Health.

“GBM AGILE is a ground-breaking trial that enables us to simultaneously and dynamically study the effects of multiple new drug candidates in an optimized learning environment. The trial’s nimble model allows us to more efficiently and rapidly identify effective therapies for GBM patients,” said Dr. Michael Lim, who also serves as a member the GBM AGILE Arm Identification and Selection Committee. “We are excited to include troriluzole and VT1021 in GBM AGILE. These investigational drugs have the potential to support improved outcomes for GBM patients, who desperately need more effective treatment options.”

GBM AGILE is an international, innovative platform trial designed to more rapidly identify and confirm effective therapies for patients with glioblastoma through response adaptive randomization and a seamless phase 2/3 design. The trial, conceived by over 130 key opinion leaders, is conducted under a master protocol, allowing multiple therapies or combinations of therapies from different pharmaceutical partners to be evaluated simultaneously. With its innovative design and efficient operational infrastructure, data from GBM AGILE can be used as the foundation for a new drug application (NDA) and biologics license application (BLA) submissions and registrations to the FDA and other health authorities.

The new interventions are opening first at Henry Ford Health Cancer in Detroit under Henry Ford site Principal Investigator Dr. Tom Mikkelsen and will subsequently open at more than 40 trial sites across the United States with additional global sites to follow.

“Glioblastoma is a devasting disease with few effective treatment options and no cure. Currently the average survival rate is estimated to be only eight months,” noted Dr. Mikkelsen. “We are enthusiastic to be the first site to activate troriluzole and VT1021 in the GBM AGILE study. We are committed to finding our patients the best possible treatments.”

Biohaven’s troriluzole is a novel, orally administered small molecule that modulates glutamate, the most abundant excitatory neurotransmitter in the human body. Troriluzole is thought to restore glutamate homeostasis by enhancing glutamate cycling, decreasing presynaptic glutamate release, and augmenting the expression and function of excitatory amino acid transporters (i.e., EAAT2) located on glial cells that play a key role in clearing excess glutamate from the synapse. Troriluzole was selected for inclusion in GBM AGILE, based on compelling evidence showing deregulation of glutamate in glioblastoma. The therapeutic potential of troriluzole in glioblastoma and other oncology indications is supported by several recent clinical and translational research studies conducted with troriluzole and its active moiety.

“The initiation of this pivotal trial of troriluzole for glioblastoma is an exciting milestone,” commented Dr. Vlad Coric, Chairman and Chief Executive Officer of Biohaven. “We are extremely proud to be joining the highly innovative GBM AGILE trial. We look forward to collaborating with the Principal Investigators, Drs. Lim and Weller, the team at GCAR, and the GBM AGILE trial sites in order to rapidly advance the development of troriluzole in combination with standard of care therapies as a novel treatment for people suffering from glioblastoma, which is amongst the most recalcitrant and lethal of all cancers.”

Vigeo’s VT1021, is a first-in-class dual modulating compound that blocks the CD47 immune checkpoint and activates the apoptotic and macrophage reprogramming activity of CD36. The result of the dual modulating activity is the induction of apoptosis in tumor and endothelial cells, as well as an increase in both CTL:Treg and M1:M2 macrophage ratio. The biological/therapeutic activity of VT1021 is mediated by the stimulation of thrombospondin-1 (Tsp-1). Through these dual-modulating effects VT1021 reprograms the tumor microenvironment from one that is immune suppressive, or “cold,” to immune enhanced (or sensitized), or “hot,” that are more susceptible to attack from the immune system. With its novel mechanism of action and clinical data from a Phase 2 expansion study in recurrent GBM patients, VT1021 is undergoing further studies to determine its effect in treating the disease, given that CD36 and CD47 are found to be highly expressed in tumor cells compared to normal brain tissue. Vigeo is developing VT1021 as a therapeutic agent across a range of cancers, with a current focus on solid tumors.

“VT1021 has seen remarkable patient response, with a great safety profile, in our earlier clinical trials. We are excited that VT1021 is included as part of this global, multi-site effort to treat such a devastating disease,” said Jim Mahoney, Chief Executive Officer, Vigeo Therapeutics. “The opportunity to work with these distinguished Principal Investigators and to test our drug in both newly diagnosed and recurrent GBM patient populations are key factors in our decision to join AGILE.”
