Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective, Bayesian adaptive, phase II clinical trial designed to evaluate the safety and efficacy of four treatment regimens in patients with recurrent (unamenable to local therapy) or metastatic nasopharyngeal carcinoma (NPC) who have failed after at least one prior platinum-containing standard regimen and anti-PD-1/PD-L1 therapy.

The four treatment arms include:

1. Ivonescimab monotherapy,
2. Ivonescimab combined with nimotuzumab,
3. Liposomal mitoxantrone plus anti-PD-1 antibody, and
4. Liposomal irinotecan plus S-1.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with recurrent (not amenable to local therapy) or metastatic nasopharyngeal carcinoma (NPC) who have progressed after at least one prior platinum-containing standard regimen and anti-PD-1/PD-L1 therapy are eligible for this study. This trial adopts a Bayesian Adaptive Randomization with Constant Power parameter (BARCP) design. The planned maximum sample size is 208 patients, with a minimum of 32 patients to be enrolled before potential early termination for futility or efficacy based on interim analysis.

The first 40 patients will be randomized with equal probability to one of the four treatment arms:

1. Ivonescimab monotherapy
2. Ivonescimab combined with nimotuzumab
3. Liposomal mitoxantrone plus an anti-PD-1 antibody
4. Liposomal irinotecan plus S-1

Subsequent randomization probabilities will be updated based on objective response rate (ORR) using interim analyses, which will include decisions for early efficacy, futility, or reassignment of allocation probabilities for future participants. Interim analyses will be conducted every time 16 new patients complete ORR assessment. The minimum allocation probability for each treatment arm is constrained to 5%.

All patients will receive treatment until disease progression (as determined by the investigator based on RECIST 1.1 criteria), intolerable toxicity, withdrawal of informed consent, initiation of new anticancer therapy, loss to follow-up, death, or study completion-whichever occurs first. Regular visits and imaging assessments will be conducted to evaluate the efficacy and safety of the treatment regimens.
