A Phase 1 Trial of Oncolytic Measles Virotherapy in Mesothelioma


Rochester, Minn.

Trial status:

Open for Enrollment

Why is this study being done?

PRIMARY OBJECTIVES: Maximum tolerated dose (MTD) for the intrapleural administration of a modified vaccine strain measles virus (MV) genetically engineered to produce human thyroidal sodium iodine symporter (NIS) (MV-NIS [oncolytic measles virus encoding thyroidal sodium iodide symporter])in patients with MPM. SECONDARY OBJECTIVES: Safety and toxicity of the repeated (up to 6 cycles) intrapleural administration of MV-NIS in patients with malignant pleural mesothelioma. TERTIARY OBJECTIVES: I. Time course of viral infection, dissemination and elimination by non-invasive measurements of NIS gene expression using radioactive iodine and single-photon emission computed tomography (SPECT)/ computed tomography (CT) imaging with. II. Viremia, viral replication, and viral shedding following intrapleural administration. III. Changes in humoral and cellular anti-MV immunity following the intrapleural administration of MV-NIS. IV. Antitumor efficacy of this approach by serial measurements of radioiodine uptake by SPECT/CT, radiographic response, and time to disease progression. V. Changes in both local and systemic innate and adaptive anti-tumor immunity following the intrapleural administration of MV-NIS. VI. Effect of MV-NIS administration on the eukaryotic initiation factor (eIF) 4F translation complex in mesothelioma cells. OUTLINE: This is a dose-escalation study. Patients receive the oncolytic measles virus encoding thyroidal sodium iodide symporter (MV-NIS) intrapleurally. In the absence of unacceptable side effects or disease progression treatment can be repeated every 28 days for up to 6 courses. After completion of study treatment, patients are followed up every 3 to 6 months for up to 5 years.
