Overview
Brief Summary
This is an open-label, multi-center, dose-escalation study with expansion cohorts, designed to evaluate the safety and anti-tumor activity of LYL845, an epigenetically reprogrammed tumor infiltrating lymphocyte (TIL) therapy, in participants with relapsed or refractory (R/R) metastatic or locally advanced melanoma, non-small cell lung cancer (NSCLC), and colorectal cancer (CRC).
Detailed Description
This is an open-label, multi-center, dose-escalation study with expansion cohorts, designed to evaluate the safety and anti-tumor activity of LYL845, an epigenetically reprogrammed tumor infiltrating lymphocyte (TIL) therapy, in participants with relapsed or refractory (R/R) metastatic or locally advanced melanoma, non-small cell lung cancer (NSCLC), and colorectal cancer (CRC). During the dose-escalation phase of the study (Part A), participants with melanoma will be enrolled. Once a safe recommended Phase 2 dose range (RP2DR) has been established in Part A, enrollment will be expanded (Part B) to include additional participants with melanoma, NSCLC and CRC.

Eligibility Criteria
Inclusion Criteria
- •Age ≥ 18 years up to ≤ 75 years at the time of informed consent
- •Confirmed diagnosis of melanoma, non-small cell lung cancer (NSCLC), or colorectal cancer (CRC) that is metastatic or locally advanced or unresectable and is relapsed and/or refractory (R/R) after standard therapy for each tumor histology
- •Participants must have received prior systemic treatment for their metastatic disease or locally advanced disease based on tumor type as follows:
- •Melanoma: participants with disease progression following an immune checkpoint inhibitor (CPI)
- •NSCLC: participants with disease progression following at least 1 approved systemic therapy, including an immune CPI-containing regimen for appropriate patients or an approved targeted therapy for known molecular abnormalities if applicable to their disease
- •CRC: participants with disease progression following at least 1 line of therapy, including a fluoropyrimidine with oxaliplatin or irinotecan. Microsatellite instability (MSI) high/mismatch repair deficient (dMMR) CRC participants must have disease progression following systemic therapy with immune CPIs.
- •Measurable disease including at least 1 lesion that is safely resectable AND a target lesion to measure response and an additional lesion for biopsy
- •Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
- •Adequate organ and marrow function
- •Women of childbearing potential must have a negative pregnancy test at screening
Exclusion Criteria
- •Prior treatment with adoptive cellular therapy
- •Prior solid organ transplantation
- •Central nervous system (CNS) involvement of disease that is extensive, symptomatic or untreated, or patients with leptomeningeal disease
- •Uncontrolled or symptomatic pleural effusion or ascites
- •Untreated or active systemic infection
- •Active autoimmune disease requiring treatment or primary immunodeficiency syndrome
- •Systemic corticosteroids at a dose of \>10 mg of prednisone or equivalent per day
- •Other primary malignancy within 3 years prior to enrollment
- •Impaired cardiac function or clinically significant cardiovascular disease
- •Required chronic anticoagulation, such as warfarin, low molecular weight heparin, or Factor Xa inhibitors
