About

This study evaluates the safety and efficacy of AL3818 (anlotinib) hydrochloride in combination with Opdivo (nivilumab) for the treatment patients with of metastatic, advanced, or recurrent solid tumors. All participants will receive open-label AL3818 with nivolumab. Part 1 consists of a dose finding phase to determine the recommended phase 2 dosage of AL3818 with nivolumab. Part 2 consists of a dose expansion phase, evaluating the safety and efficacy of the combination in patients cohorts including metastatic, advanced, or recurrent soft tissue sarcomas, non-small cell lung cancer, and small cell lung cancer.

Full description

This phase 1b/2 study evaluates the safety and efficacy of AL3818 (anlotinib) hydrochloride in combination with Opdivo (nivilumab) for the treatment patients with of metastatic, advanced, or recurrent solid tumors including soft tissue sarcomas (STS), non-small cell lung cancer (NSCLC), and small cell lung cancer (SCLC). All participants will receive open-label AL3818 with nivolumab on a scheduled basis.

Part 1 (phase 1b) consists of a dose finding phase to determine the safety, tolerability (including recommended phase 2 dosage (RP2D), and PK profile of AL3818 given with nivolumab. Participants will receive oral AL3818 once daily on Days 1-14 and nivolumab injection on Day 1 and 15 of one 21-day cycle.

Part 2 (phase 2a) consists of a dose expansion phase, to evaluate the safety and preliminary efficacy of combination treatment using AL3818 at the RP2D determined from Part 1 together with nivolumab injection at standard dosing for patients with metastatic, advanced, or recurrent STS, NSCLC, or SCLC in 21-day cycles. Oral AL3818 will be given on Days 1-14 days and nivolumab will be given every 2 weeks, for up to 24 cycles of total AL3818 therapy.

Description:

Part 1: All participants will be assigned to receive AL3818 capsules orally, once daily at sequential deescalating doses (on treatment Days 1-14 followed by no AL3818 treatment from Days 15-21) in combination with nivolumab injection treatment (on Day 1 and Day 15) for a single 21-day cycle.
