Safety and Efficacy Study of REOLYSIN® in the Treatment of Bone and Soft Tissue Sarcomas Metastatic to the Lung

Descriptive Information
Brief Title † Safety and Efficacy Study of REOLYSIN® in the Treatment of Bone and Soft Tissue Sarcomas Metastatic to the Lung
Official Title † A Phase 2 Study of Intravenous REOLYSIN® (Wild-Type Reovirus) in the Treatment of Patients With Bone and Soft Tissue Sarcomas Metastatic to the Lung
Brief Summary The purpose of this Phase 2 study is to investigate whether intravenous administration of REOLYSIN® therapeutic reovirus is safe and effective in the treatment of patients with bone and soft tissue sarcomas metastatic to the lung.
Detailed Description Sarcomas are uncommon mesenchymal malignancies that encompass a variety of tumors of soft tissue or bone. Included in this study are patients with osteosarcoma, Ewing sarcoma family tumors, malignant fibrous histiocytoma, synovial sarcoma, leiomyosarcoma and fibrosarcoma. Patients with these lesions presenting with metastatic disease remain largely incurable. In all sarcomas, the lungs are by far the most frequent site of metastases. There is a need for new therapies that have activity against these types of sarcomas. REOLYSIN® is an unmodified oncolytic reovirus which replicates selectively in ras transformed cells causing cell lysis. Activating mutations in ras or mutations in oncogenes signaling through the ras pathway may occur in as many as 80% of human tumors. Such mutations have been described in many of the common sarcomas of childhood and adults. REOLYSIN® demonstrated excellent anti-tumor activity in vitro and in vivo in childhood sarcoma cell lines. Further supporting the development of REOLYSIN® in the context of sarcomas as detailed in this study, is the fact that sarcomas resistant or refractory to conventional chemotherapy may remain clinically responsive to viral therapy. Sarcoma patients with pulmonary metastases may be especially suitable for studies with REOLYSIN® due to rapid selective uptake of the virus by the lungs. This Phase 2 study is designed to characterize the efficacy and safety of REOLYSIN® given intravenously over 5 days every 4 weeks in patients with bone and soft tissue sarcomas metastatic to the lung. Safety data, including laboratory parameters and adverse events, will be collected for all patients in order to determine the toxicity and reversibility of toxicity of REOLYSIN® therapy. Response will be assessed using radiographic imaging every 2 cycles of therapy. OBJECTIVES: 1. To measure tumor responses and duration of response, and describe any evidence of antitumor activity of intravenous multiple dose REOLYSIN® in patients with bone and soft tissue sarcomas metastatic to the lung. 2. To evaluate safety of intravenous multiple dose REOLYSIN®.
