Sotevtamab (AB-16B5) Combined With FOLFOX as Neoadjuvant Treatment Prior to Resection of Colorectal Cancer Liver Metastasis

This is an open-label, single-arm, single-center proof-of-concept Phase II trial of sotevtamab in combination with FOLFOX-based preoperative neoadjuvant systemic chemotherapy in participants with resectable liver-dominant metastases and candidate to neoadjuvant FOLFOX followed by partial hepatectomy. Approximately 17 participants will be enrolled in this trial and will receive 4 cycles of FOLFOX (Cycle 1 to Cycle 4) as preoperative systemic chemotherapy and 6 cycles of sotevtamab (Cycle 1 to Cycle 6). One cycle of treatment will consist of 14 days (2 weeks). Sotevtamab will be administered by intravenous (IV) infusion at 800 mg on Day 1 and Day 8 of each cycle. FOLFOX will be administered on Day 1 of Cycle 1 to Cycle 4 as follows: oxaliplatin 85 mg/m² IV infusion + leucovorin 400 mg/m² IV infusion + 5-Fluorouracil (5-FU) 400 mg/m² IV bolus + 5-FU 2400 mg/m² continuous IV infusion over 46 hours. Participants will undergo liver metastasis resection with or without primary cancer resection following recovery from preoperative neoadjuvant systemic chemotherapy.
