|Official Title:||An Open Label Phase I Study to Evaluate the Safety and Efficacy of OBP-301 With Pembrolizumab in Patients With Advanced Solid Tumors|
|Actual Study Start Date :||October 1, 2017|
|Estimated Primary Completion Date :||April 2021|
|Estimated Study Completion Date :||May 2022|
Intratumoral injection directly into the dose target region of a tumor at Day 1, Day 15, and Day 29.
Additional administration of OBP-301 After the recommended dose of OBP-301 has been established, additional administration of OBP-301 is allowed. After completion of administration of OBP-301 on Day 1 - Day 29(+/- 4 days), if the target region has not disappeared, additional administration of OBP-301 is allowed after Day 43 or later.
The patients in Phase 1a, Pembrolizumab administration has continued, are included.
The recommended dose determined in the Phase 1a part will be administered 3 times biweekly (+/- 4 days); max 4 cycles.
200 mg Pembrolizumab is infused intravenously at Day 8. Thereafter infusion will continue every 3 weeks until discontinuation.
- Dose limiting toxicity (DLT) [ Time Frame: 4weeks ]Dose limiting toxicity
- Response rate (RR) [ Time Frame: 3 years ]Response rate by RECIST ver. 1.1
- Progression free survival (PFS) [ Time Frame: 3 years ]Progression free survival
- Rate of adverse event [ Time Frame: 3 years ]Rate of adverse event
- Biomarkers:Efficacy evaluations according to immune status [ Time Frame: 3 years ]Immune status will be analyzed using biopsy and blood samples by flow cytometry, RNA seq, whole exome sequencing, and immunohistochemistry, etc.
