ITIL-168 in Advanced Melanoma (DELTA-1)

April 12, 2024 updated by: Instil Bio

A Phase 2, Open-label, Multicenter Study Evaluating the Safety and Efficacy of Autologous Tumor-infiltrating Lymphocytes (TILs) in Subjects With Advanced Melanoma (DELTA-1)

DELTA-1 is a phase 2 clinical trial to evaluate the efficacy and safety of ITIL-168 in adult subjects with advanced melanoma who have previously been treated with a PD-1 inhibitor. ITIL-168 is a cell therapy derived from a patient's own tumor-infiltrating immune cells (lymphocytes; TILs).

Description

Key Inclusion Criteria:

  • Histologically confirmed advanced (unresectable or metastatic) cutaneous melanoma.
  • Cohort 1: Disease that is relapsed after or refractory to at least 1 prior line of systemic therapy that must include a PD-1 inhibitor and, if positive for proto- oncogene BRAF V600 activating mutation, targeted therapy.
  • Cohort 2: Disease that is persistent after discontinuing PD-1 due to toxicity. Patients with a proto-oncogene BRAF V600 activating mutation must have progressed after targeted therapy.
  • Cohort 3: Disease that is stable (SD) after at least 4 doses of a PD-1 inhibitor. Patients with a proto-oncogene BRAF V600 activating mutation must have progressed after targeted therapy.
  • 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
  • Melanoma of uveal, acral, or mucosal origin
  • 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, or IL-2.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Cohort 1
Patients who relapsed after or were refractory to at least 1 prior line of systemic therapy including a PD-1 inhibitor.
ITIL-168 is a cell therapy product derived from a patient's own TILs. A tumor sample is removed from each patient to make a personalized ITIL-168 product. Once ITIL-168 has been made, the patient is treated with 5 days of lymphodepleting chemotherapy including cyclophosphamide and fludarabine, followed by a single infusion of ITIL-168, and up to 8 doses of IL-2.
Experimental: Cohort 2
Patients who were intolerant to a PD-1 inhibitor and have persistent disease after stopping PD-1 therapy.
ITIL-168 is a cell therapy product derived from a patient's own TILs. A tumor sample is removed from each patient to make a personalized ITIL-168 product. Once ITIL-168 has been made, the patient is treated with 5 days of lymphodepleting chemotherapy including cyclophosphamide and fludarabine, followed by a single infusion of ITIL-168, and up to 8 doses of IL-2.
Experimental: Cohort 3
Patients who had a best response of stable disease despite being treated with at least 4 doses of a PD-1 inhibitor in the previous line of therapy.
