A Single-arm, Open-label, Clinical Trial of Surufatinib/Serplulimab/Platinum/Etoposide in Neuroendocrine Carcinoma.

July 12, 2026 updated by: Union Hospital, Tongji Medical College, Huazhong University of Science and Technology

A Single-arm, Open-label, Single-center Clinical Trial of Surufatinib and Serplulimab Combined With Standard Chemotherapy (Platinum/Etoposide) in Neuroendocrine Carcinoma.

This study is a prospective open-label, single-arm, single-center clinical study. Patients with neuroendocrine carcinoma who had not previously received standard therapy were enrolled in this study once they have signed the informed consent form (ICF) and been identified as eligible in screening. This clinical trial evaluates the efficacy and safety of surufatinib and serplulimab combined with standard chemotherapy (Platinum/Etoposide) in neuroendocrine carcinoma.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No
