Intravenous Injection of Oncolytic Virus Injection (RT-01) in Patients With Relapsed or Refractory T-cell Lymphoma

A Sing-Arm, Open Clinical Pharmacology Study of Intravenous Injection of Oncolytic Virus Injection (RT-01) in Patients With Relapsed or Refractory T-cell Lymphoma

This is a single-arm, open-label, clinical pharmacology study to evaluate safety and efficacy of oncolytic virus injection(RT-01) in patients with Relapsed or Refractory T-cell Lymphoma. The purpose of this study is to evaluate the safety and tolerability, antitumor activity, The immunoreactivity, The immunogenicity, pharmacokinetics and virus shedding of RT-01.

This is an investigator initiated , single-arm, open-label clinical pharmacology study of RT-01 given via Intravenous injection in patients with advanced solid tumors. RT-01 will be administered on days 1 and 6, and every 8 weeks thereafter (up to 6 times).

This study is planned to enroll 6 patients with Relapsed or Refractory T-cell Lymphoma.

The purpose of this study is to assess the safety and tolerability, antitumor activity, The immunoreactivity, The immunogenicity, pharmacokinetics and virus shedding of RT-01.
