Open Actively Recruiting

A Study to Investigate LYL845 in Adults With Solid Tumors


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).

Primary Purpose
Study Type
Phase 1


Healthy Volunteers
Minimum Age
18 Years
Maximum Age
75 Years

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
  • All participants must agree to practice highly effective methods of contraception
  • Fully recovered from toxicity from prior systemic anticancer therapy

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
