This study evaluates an oncolytic virotherapy (MV-NIS, an engineered measles virus given intravenously) in patients with relapsed high-risk multiple myeloma. Adults aged 18-75 with confirmed high-risk multiple myeloma that relapsed after stem cell transplant and with low measles antibody levels were able to take part. The study was carried out in Phase 2 and has been completed.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
Inclusion Criteria: * Relapsed patients must have a confirmed MM diagnosis with high-risk disease as defined by GEP70 risk score ≥ 0.66 or GEP80 gene score of ≥ 2.48 or metaphase cytogenetic abnormalities or LDH ≥ 360 U/L due to MM (Rule out hemolysis, infection and contact PI for clarification if any doubt). Patients must have relapsed after auto-PBSCT followed by further chemotherapy * ≥2 months must have elapsed after the last peripheral blood stem cell transplant prior to enrollment * Zubrod ≤ 2, unless solely due to symptoms of MM-related (bone) disease * Patients must have a platelet count of ≥ 20,000/µL within 45 days of registration, unless lower levels are explained by extensive BM plasmacytosis or extensive prior therapy * Patients must be at least 18 years of age and not older than 75 years of age at the time of registration * Participants must have preserved renal function as defined by a serum creatinine level of ≤ 3 mg/dL within 45 days of registration * Participants must have an ejection fraction by ECHO or MUGA scan ≥ 40% within 45 days prior to registration * Patients must have adequate pulmonary function studies \> 50% of predicted on mechanical aspects (FEV1, etc) and diffusion capacity (DLCO) \> 50% of predicted within 45 days prior to registration. If the patient is unable to complete pulmonary function tests due to MM related pain or condition, exception may be granted * Patients must have signed an IRB-approved informed consent and Health Insurance Portability and Accountability Act (HIPAA) authorization form * Patients must have anti-MV IgG titer of ≤ 0.5U/mL (Mayo clinic assay). Mayo Clinic will also assay the patients' IgM titer and perform a neutralizing antibody plaque-assay to determine recent MV exposure and the ability of the patients' circulating antibodies to inhibit MV propagation on Vero cells, respectively. While these tests are additional indicators of patient eligibility, final enrollment decision will be determined by IgG levels Exclusion Criteria: * Patients may not be positive for the Human Immunodeficiency Virus (HIV) * History of poorly controlled hypertension, diabetes mellitus, or any other serious medical illness or psychiatric illness that could potentially interfere with the completion of treatment according to this protocol or could be considered to be an exclusion criterion deemed by the PI * Patients must not have prior malignancy, except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, or other cancer for which the patient has not received treatment for one year prior to enrollment. Other cancers will only be acceptable if the patient's life expectancy exceeds three years as determined by the PI * Pregnant or nursing women may not participate. Women of childbearing potential must have a negative pregnancy test documented within one week of registration. Women/men of reproductive potential may not participate unless they have agreed to use an effective contraceptive method * Exposure to household contacts ≤ 15 months old or household contact with known immunodeficiency
