-- Biohaven initiates a clinical trial of the novel antibody recruiting molecule BHV-1100 to assess safety, tolerability, and exploratory clinical activity in Multiple Myeloma
-- BHV-1100 targets the destruction of CD38-expressing cells in combination with autologous cytokine induced memory-like (CIML) natural killer (NK) cells and immune globulin (Ig) in multiple myeloma patients undergoing autologous stem cell transplant
-- FDA previously provided Orphan Drug designation for BHV-1100 in Multiple Myeloma
NEW HAVEN, CT, USA I October 27, 2021 I Biohaven Pharmaceutical Holding Company Ltd. (NYSE: BHVN), announced the enrollment of the first patient in a Phase 1a/1b trial in Multiple Myeloma using the ARM, BHV-1100, in combination with autologous cytokine induced memory-like (CIML) natural killer (NK) cells and immunoglobulin (Ig) to target and kill multiple myeloma cells expressing the cell surface protein CD38 (Figure 1). BHV-1100 is the lead clinical asset from Biohaven's ARM Platform, developed from a strategic alliance with PeptiDream Inc. This clinical trial will assess the safety and tolerability, as well as exploratory efficacy endpoints, in newly diagnosed multiple myeloma patients who have tested positive for minimal residual disease (MRD+) in first remission prior to autologous stem cell transplant (ASCT).
NK cells are part of the innate immune system, which is designed to recognize and destroy "non-self" or diseased cells in the body. However, tumor cells can evade detection by immune effector cells, allowing the tumor to advance. BHV-1100 targets a cell-surface protein, CD38, that is heavily overexpressed on multiple myeloma and binds to it, recruiting primed autologous cytokine induced memory-like (CIML) natural killer (NK) cells to destroy the tumor.
Charlie Conway, Ph.D., Chief Scientific Officer at Biohaven commented, "While many recent advances have been made to benefit multiple myeloma patients, most patients will unfortunately still relapse. We are excited to investigate BHV-1100 for its ability to recruit autologous CIML NK cells to the site of the tumor. Based on preclinical data from Biohaven Labs, we anticipate that our CD38 targeting ARM-enabled NK cells will kill CD38-positive multiple myeloma cells, and recruit other immune effector cells to assist in reducing the tumor burden."
Biohaven has initiated enrollment in the clinical trial and plans to enroll 25 patients for this single-center, open-label study (ClinicalTrials.gov Identifier: NCT04634435; https://clinicaltrials.gov/ct2/show/NCT04634435). The study will enroll newly diagnosed multiple myeloma patients who have minimal residual disease (MRD+) in first remission prior to an autologous stem cell transplant (ASCT).
David Spiegel M.D., PhD, inventor of the ARM technology and Professor of Chemistry and Pharmacology at Yale University, commented, "This is an important milestone in the development of the ARM therapeutic platform – taking a novel technology from 'benchtop to bedside'. It also highlights Biohaven's commitment to benefit patients in need."
About ARMs: Antibody Recruiting Molecules
ARMs, antibody recruiting molecules, are engineered with modular components that are readily interchangeable, giving the platform tremendous flexibility and rapid development timelines. ARM compounds are being developed at Biohaven Labs to redirect a patient's own antibodies for therapeutic effect with multiple benefits over traditional monoclonal antibody therapies, including the potential for oral dosing. For BHV-1100, the ARM platform is being used to provide antigen targeting to NK cell-based therapies without genetic engineering. This NK cell targeting approach is also being investigated with allogeneic, or 'off-the-shelf', immune cell-based therapies.
About Multiple Myeloma
Multiple myeloma is a type of blood cancer of the plasma cell that develops in the bone marrow, the soft tissue inside our bones. Healthy plasma cells produce antibodies, which are critical for the immune system's ability to recognize disease-causing entities, such as bacteria, viruses and tumor cells. In multiple myeloma, however, genetic abnormalities in a single plasma cell cause it to divide uncontrollably. This leads to the over-production of a single (monoclonal) antibody protein, referred to as an "M protein". Also, these cancerous cells divide to the point of crowding out normal, healthy cells that reside in the bone marrow. Many patients are diagnosed due to symptoms such as bone pain or fractures, kidney failure (thirst, dehydration, confusion), nerve pain, fever, and weakness. The American Cancer Society estimates that approximately 34,920 new cases will be diagnosed, and 12,410 deaths will occur in 2021 from multiple myeloma.
