研究概览
简要总结
The primary objective is to evaluate major pathologic response after RiMO-301 with hypofractionated radiotherapy and a PD-1 inhibitor (pembrolizumab), as assessed by clinical response rate using iRECIST criteria; determine event-free survival for up to 12 months; and determine overall survival for up to 24 months. The secondary objectives include determining event-free survival for up to 12 months and overall survival for up to 24 months.
详细描述
RiMO-301 is administered intratumorally once prior to radiotherapy, with or without ultrasound/computed tomography (CT) guidance, at 30% of tumor volume(s). Radiotherapy (RT) is given starting within 1 day after RiMO-301 injection for 5 fractions of (4-5) Gray per fraction over a period of 5-15 days. PD-1 inhibitor pembrolizumab will be administered via 30-minute intravenous infusion, respectively, 200 mg once every three weeks (Q3W) with the first dose on the same day as RiMO-301 injection (+/- 1 day) for two cycles. Assessment of response will be clinically confirmed with CT imaging studies performed 5 weeks after the last radiation and pathology evaluation of the resected tumor. Event-free survival will be clinically evaluated every three months up to 12 months, CT imaging studies will be performed every 6 months after surgery up to 12 months after surgery, and overall survival will be clinically evaluated up to two years.

- •Have adequate bone marrow reserve:
- •Absolute neutrophil count ≥1.5x109 cell/L
- •Platelet count ≥100x109 cell/L
- •Hemoglobin at least ≥9.0 g/dL unless confirmed by treating physician as not posing any increased harm to patient and approved by Sponsor (transfusion is allowed to achieve hemoglobin of ≥9.0 g/dL 14-days prior to dosing)
- •Have adequate liver function:
- •Total serum bilirubin no more than 1.5x upper limit of normal (ULN)
- •Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5x ULN or ≤5.0x ULN in case of documented hepatic metastasis

排除标准

研究组 & 干预措施
RiMO-301 combined with radiotherapy and pembrolizumab followed by surgical resection
RiMO-301 will be injected intratumorally once prior to radiotherapy at 30% of tumor volume(s). Radiotherapy will start within 1 day after the RiMO-301 injection for 5 fractions of 4-5 Grays per fraction over a period of 5-15 days. Pembrolizumab 200 mg will be administered intravenously every 3 weeks (Q3W) within the first dose given on the same day as the RiMO-301 injection (+/-1 day). Pembrolizumab will continue for 2 cycles (1 cycle = 21 days). Surgical resection of the tumor will occur after the completion of neoadjuvant therapy.
