ITIL-168 in Advanced Solid Tumors

Phase 1
Withdrawn
Conditions
Cervical Cancer
Non-small Cell Lung Cancer
Head and Neck Squamous Cell Carcinoma
Interventions
Biological: ITIL-168
Registration Number
NCT05393635
Lead Sponsor
Instil Bio
Brief Summary

DELTA-2 is a phase 1 clinical trial to evaluate the safety, feasibility, and preliminary efficacy of ITIL-168 with pembrolizumab in participants with advanced cancer whose disease has progressed after standard therapy. ITIL-168 is a cell therapy derived from a patient's own tumor-infiltrating immune cells (lymphocytes; TILs).

Inclusion Criteria
  • Histologically documented advanced (metastatic and/or unresectable) cervical cancer, HNSCC, or NSCLC.
  • Cohort 1: Participants with cervical cancer whose disease progressed during or after at least 1 prior line of chemotherapy.
  • Cohort 2: Participants with HNSCC whose disease progressed during or after chemotherapy that must have included a platinum agent and previous CPI.
  • Cohort 3: Participants with NSCLC whose disease progressed during or after 1 prior line of platinum-based chemotherapy and a CPI. Participants with targetable mutations (e.g. EGFR/ALK) are required to have progressed on targeted therapy and platinum-based chemotherapy
  • Medically suitable for surgical resection of tumor tissue
  • Following tumor resection for TIL harvest, will have, at minimum, 1 remaining measurable lesion as identified by CT or MRI per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1
  • Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1
  • Adequate bone marrow and organ function

Cohort 1ITIL-168Participants with cervical cancer whose disease has progressed during or after treatment with platinum-based chemotherapy. Participants with combined positive score ≥ 1 should also have disease that has progressed during or after treatment with CPI.
Cohort 2ITIL-168Participants with head and neck squamous-cell carcinoma (HNSCC) whose disease has progressed during or after platinum-based chemotherapy and previous CPI.
Cohort 3ITIL-168Participants with non-small cell lung cancer (NSCLC) whose disease has progressed during or after platinum-based chemotherapy and a CPI. Participants with targetable mutations (e.g. EGFR/ALK) are required to have disease which has progressed on targeted therapy and platinum-based chemotherapy.
Primary Outcome Measures
NameTimeMethod
Frequency and severity of ITIL-168 treatment-emergent adverse events (AEs), serious AEs, and AEs of special interestUp to 24 months
Secondary Outcome Measures
NameTimeMethod
Progression-free SurvivalUp to 60 months

Progression-free survival (PFS) is defined as the time from the ITIL-168 infusion date to the date of disease progression or death from any cause.

Objective response rateUp to 60 months

Objective response rate (ORR), defined as the incidence of a complete response (CR) or a partial response (PR) per a modified Response Evaluation Criteria in Solid Tumors (RECIST v1.1) criteria, as assessed by investigator review.

Duration of responseUp to 60 months

For participants who experience an objective response, duration of response (DOR) is defined as the time from their first objective response to disease progression or death.

Overall SurvivalUp to 60 months

Overall survival (OS) is defined as the time from the ITIL-168 infusion date to the date of death from any cause.
