Status Not yet recruiting

Clinical Trial Summary

The purpose of this study is to evaluate the efficacy and safety of allogeneic γδ T cells combined with recombinant human interferon-α1b (IFN-α1b) or PD-1 monoclonal antibody in neoadjuvant treatment of patients with Stage III-IV resectable melanoma.

Clinical Trial Description

This is a double-arm, single-center, randomized, open label Phase I clinical trial to evaluate the efficacy and safety of the combination of ex-vivo expanded allogeneic γδ T cells plus recombinant human interferon α1b or PD-1 monoclonal antibody in patients with Stage III-IV resectable melanoma(AJCC 8th). We randomly assigned patients with stage III-IV melanoma that was amenable to surgical resection to three doses of neoadjuvant γδT cells plus IFN-α1b or γδT cells plus pembrolizumab , surgery, and 15 doses of adjuvant γδT cells plus IFN-α1b or γδT cells plus pembrolizumab. The primary endpoints are pathological response rate after 3 cycles of treatment, including: complete pathological response rate (pCR), major pathological response rate (MPR), partial pathological response rate (pPR); preoperative imaging response rate (RECIST v1.1) was evaluated, including complete response (CR), partial response (PR), stable disease (SD), and disease progression (PD); and proportion of patients who do not need surgery due to remission. The second endpoints are event-free survival (EFS), relapse free survival (RFS), and overall survival (OS, 3 years after surgery). The safety profile of the combined γδT cells/IFN-α1b regimen and γδT cells/ pembrolizumab regimen will be monitored, we will evaluate the numbers and severity of toxicity per the Criteria for Adverse Events version 5 (CTCAEv) including but not limited to all adverse events (AE), incidence of surgery-related adverse events, and proportion of inoperable patients (due to disease progression or treatment-related adverse events). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
