Details and patient eligibility

About

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).

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion and exclusion criteria

Key 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

Key Exclusion Criteria:

• History of another primary malignancy within the previous 3 years
• Neuroendocrine carcinoma, nasopharyngeal carcinoma, squamous cell carcinoma of the lip, or histopathology with neuroendocrine differentiation
• Previously received an allogeneic stem cell transplant or organ allograft
• Previously received TIL or engineered cell therapy (eg, CAR T-cell)
• Significant cardiac disease
• Stroke or transient ischemic attack within 12 months of enrollment
• History of significant central nervous system (CNS) disorder
• Symptomatic and/or untreated CNS metastases
• History of significant autoimmune disease within 2 years prior to enrollment
• Known history of severe, immediate hypersensitivity reaction attributed to cyclophosphamide, fludarabine, IL-2, of CPI

0 participants in 3 patient groups

Cohort 1

Experimental group

Description:

Participants 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.

Treatment:

Biological: ITIL-168

Cohort 2

Experimental group

Description:

Participants with head and neck squamous-cell carcinoma (HNSCC) whose disease has progressed during or after platinum-based chemotherapy and previous CPI.

Treatment:

Biological: ITIL-168

Cohort 3

Experimental group

Description:

Participants 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.
