A Study to Investigate LYL845 in Adults With Solid Tumors

This is an interventional treatment trial for Melanoma focused on measuring TIL, tumor infiltrating lymphocyte, melanoma, non-small cell lung cancer, colorectal cancer, NSCLC, CRC, relapsed, refractory, locally advanced, advanced, metastatic, epigenetic Read More

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) and if BRAF-mutated, BRAF/MEK inhibition
• 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
• All participants must agree to practice highly effective methods of contraception

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
• Pregnant or nursing (lactating) women
