| الوصف: | 4098 Background: In HCC, surgical resection is associated with high recurrence rate, and no effective neoadjuvant or adjuvant therapies currently exist. On the basis of of previous reports on the efficacy and safety of anti–PD-1 (nivolumab) and anti–CTLA-4 (ipilimumab) antibodies against HCC, we initiated a randomized pilot trial of perioperative immunotherapy for resectable HCC. Methods: This is a randomized, phase II pilot trial of nivolumab (Arm A) or nivolumab + ipilimumab (Arm B) as pre-operative treatment for patients (pt) with HCC who are eligible for surgical resection. Pt are given nivolumab 240 mg every 2 weeks (wk) for a total of 6 wk. Pt in Arm B are treated concurrently with ipilimumab 1 mg/kg every 6 wk. Surgical resection occurs within 4 weeks after last cycle of therapy. Pt continue adjuvant immunotherapy for up to 2 years after resection. Primary objective is the safety and tolerability of nivolumab +/- ipilimumab. Secondary objectives include overall response rate, complete response rate and time to progression. Exploratory objectives include evaluating the pre- and post-treatment immunological changes in tumor tissues and peripheral blood. Results: 17 pt were enrolled at the time of interim analysis (8 in Arm A, 9 in Arm B) and 14 were evaluable. Most pt (53%) were 60-70yo, and males (70%). 6 pt were HCV-positive and 4 had chronic hepatitis B. 14 pt proceeded with resection as planned; surgery was aborted for 2 pt (1 for frozen abdomen and 1 for development of contralateral liver nodule). One is still receiving preoperative therapy. Pathologic complete response (pCR) was observed in 4/14 evaluable pt – 2 in Arm A and 2 Arm B (29% pCR rate). 4 pt in Arm B and 1 in Arm A experienced grade 3 or higher toxicity prior to surgery. Conclusions: We report a pCR rate of 29% in an interim analysis of a phase II pilot trial of perioperative immunotherapy for resectable HCC. Treatment was safe and surgical resection was not delayed. The study is ongoing and results may contribute to a paradigm shift in the perioperative treatment of HCC. Clinical trial information: NCT03222076. |
