Spots Global Cancer Trial Database for Allogeneic Gammadelta T Cells Combined With Interferon-α1b or PD-1 Monoclonal Antibody in Stage III-IV Amenable to Surgical Resection Melanoma

Study Description

Brief 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.

Detailed 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).
