Autologous Memory-like NK Cell Therapy With BHV-1100 and Low Dose IL-2 in Multiple Myeloma Patients

Prior treatment

• Prior autologous or allogeneic hematopoietic stem cell transplant
• Prior cellular therapies, including NK cell therapy
• Prior treatment with monoclonal antibodies, within 28 days of MCN apheresis
• Prior treatment with high dose melphalan
• Prior treatment with immunosuppressive or immunomodulatory agents with exception of 5 mg or less of prednisone daily, within 14 days of MCN-Apheresis
• History of Plasma Cell Leukemia at any time prior to enrollment
• Patient receiving other investigational therapy
• Patients who have received anti-MM therapy (with the exclusion of monoclonal antibodies) within 14 days of study treatment
• More than two prior lines of anti-myeloma therapy, with induction therapy followed by maintenance being considered as one line and CyBorD to RVD transition in the absence of progressive disease being considered as one line

Other illness

• Disease progression at the time of study treatment
• Patients seropositive for the human immunodeficiency virus (HIV)
• Uncontrolled, Hepatitis C Virus or Hepatitis B Virus infection
• Patients with active, clinically significant autoimmune diseases
• Patients with active, clinically significant cancer other than multiple myeloma
• Patients with severe, uncontrolled psychiatric or neurological conditions that make difficult the assessment of neurologic toxicity of the study treatment

• Had measurable disease according to Standard Diagnostic Criteria at the time of initial Multiple Myeloma diagnosis
• Meets criteria for symptomatic multiple myeloma at the time of induction chemotherapy
• Is transplant eligible based on clinician judgement
• Willing to undergo ASCT in first or second remission
• Achieve partial response or better with induction chemotherapy prior to ASCT according to the IMWG Uniform Response Criteria for Multiple Myeloma
• Be MRD+ upon restaging prior to stem cell collection and ASCT
• Eastern Cooperative Oncology Group (EGOG) performance status score of less than 2
• Life expectancy greater than six months
• Have a creatinine clearance \> 45 mL/min/m2 at the time of transplant evaluation
• If frozen stem cells from earlier mobilized leukapheresis are unavailable at the time of mobilized leukapheresis, patients must meet parameters/criteria according to institutional SOP for autologous stem cell apheresis
• Be willing and clinically stable to undergo stem-cell mobilized and collect enough CD34+ cells sufficient for 2 ASCT per institutional guidelines or investigator discretion or have sufficient frozen cells from a SoC collection prior to signing study consent
• Be willing and clinically stable to undergo a non-mobilized MNC-Apheresis while admitted to the hospital to generate CIML NK cells
• Be willing to undergo maintenance after ASCT per NCCN guidelines based on disease risk
• If a woman of child-bearing potential, be willing to follow birth control and pregnancy testing practice as recommended
• Be willing to undergo bone marrow aspirate and biopsy as per treatment plan
• Patients must meet adequate organ function/reserve based on institutional SOP for autologous stem cell transplant eligibility
• Non-secretory MM can participate if they have measurable disease in the bone marrow and are amenable to be followed by MRD testing
