NCT04943913 | Recruiting Early Phase 1 DMC

• 1 other identifier: GC101-2021-Soochow2-BGM
• Study Type: interventional
• Target: 50
• Locations: 1 country
• Sites: 1

Brief Summary

This study is to investigate the safety and efficacy of tumor infiltrating lymphocyte (TIL) therapy in patients with malignant glioma . Autologous TILs are expanded from tumor resections and infused i.v. into the patient after NMA lymphodepletion treatment with hydroxychloroquine(600mg,single-dose) and cyclophosphamide.

Conditions

Glioma

Outcome Measures

Primary Outcomes (6)

• Adverse Events (AE)

  To characterize the safety profile of GC101 TIL in patients with advanced brain glioma as assessed by incidence of adverse events.

  1 month

• Objective Response Rate (ORR)

  Proportion of patients with response per Response Evaluation Criteria in Solid Tumors (RECIST v1.1): ORR (proportion of patients) = # with CR + # with PR / # with CR + # with PR + # with SD + # with PD. ( Except baseline evaluation within 28 days before GC101 TIL infusion，PET/CT scan will be performed at 6 weeks after TIL infusion, and than every 6 weeks for 6 months, and then every 6 months after that for up to 3 years)

  Up to 36 months

• Disease Control Rate (DCR）

  Percentage of patients that meet CR, PR and SD criteria set in this study according to RECIST 1.1

  Up to 36 months

• Duration of Response (DOR)

  The time length between the first confirmed objective response per RECIST 1.1 to the treatment and the subsequent disease progression per RECIST 1.1

  Up to 36 months

• Progression-Free Survival (PFS)

  The time length between TIL infusion and confirmed subsequent disease progression according to RECIST 1.1

  Up to 36 months

• Overall Survival (OS)

  The length of time from the date of the start of TIL treatment that the patients are still alive

  Up to 36 months

Secondary Outcomes (5)

• Complete Response(CR)

  Up to 36 months

• Partial Response (PR)

  Up to 36 months

• Stable Disease (SD)

  Up to 36 months

• Progressive Disease (PD)

  Up to 36 months

• Change in Quality of Life

  Up to 36 months
