Study to Investigate Lifileucel Regimen Plus Pembrolizumab Compared With Pembrolizumab Alone in Participants With Untreated Advanced Melanoma.

June 23, 2026 updated by: Iovance Biotherapeutics, Inc.

A Phase 3, Multicenter, Randomized, Open-label, Parallel Group, Treatment Study to Assess the Efficacy and Safety of the Lifileucel (LN-144, Autologous Tumor Infiltrating Lymphocytes [TIL]) Regimen in Combination With Pembrolizumab Compared With Pembrolizumab Monotherapy in Participants With Untreated, Unresectable or Metastatic Melanoma

This is a Phase 3, multicenter, open-label, randomized, parallel group, treatment study to assess the efficacy and safety of lifileucel in combination with pembrolizumab compared with pembrolizumab alone in participants with untreated, unresectable or metastatic melanoma. Participants randomized to the pembrolizumab monotherapy arm who subsequently have a blinded independent central review- verified confirmed progressive disease (PD) will be offered lifileucel monotherapy in an optional crossover period.

Detailed Description

The study will enroll participants with unresectable or metastatic melanoma (Stage IIIC, IIID, or IV per the American Joint Committee on Cancer [AJCC] staging system) who have had no prior therapy for metastatic disease. Previous adjuvant/neoadjuvant therapy with a single line of protooncogene B-Raf (BRAF) inhibitor with or without a mitogen-activated protein kinase (MEK) inhibitor, PD-1 inhibitor, or cytotoxic T-lymphocyte-associated antigen-4 [CTLA-4] inhibitor is allowed, provided such treatment was completed ≥6 months before progression to metastatic disease.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Participant has a histologically or pathologically confirmed diagnosis of Stage IIIC, IIID, or IV unresectable or metastatic melanoma.
  2. In the investigator's assessment, the participant has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 and an estimated life expectancy of > 6 months.
  3. Participant is assessed as having at least one resectable lesion (or aggregate lesions) for lifileucel generation.
  4. Participant must have at least one measurable disease as defined by RECIST 1.1 following tumor resection.
  5. Participants must have adequate organ function.
  6. Participants of childbearing potential or those with partners of childbearing potential must be willing to practice an approved method of highly effective birth control.
  7. Participants who are > 70 years of age may be allowed to enroll after the investigator discusses with the medical monitor.

Exclusion Criteria:

  1. Participant has melanoma of uveal/ocular origin.
  2. Participant has symptomatic untreated brain metastases.
  3. Participant received more than 1 prior line of therapy.
  4. Participant received prior therapy for metastatic disease
  5. Participants with a BRAF V600 mutation-positive tumor received prior adjuvant/neoadjuvant ICI therapy only
  6. Participant has an active medical illness(es) that, in the opinion of the investigator, would pose increased risks for study participation, such as systemic infections; seizure disorders; coagulation disorders; or other active major medical illnesses of the cardiovascular, respiratory, or immune systems.
  7. Participant has any form of primary or acquired immunodeficiency (eg, SCID or AIDS).
  8. Participant had another primary malignancy within the previous 3 years (except for those that do not require treatment or were curatively treated >1 year ago, and in the judgment of the investigator do not pose a significant risk of recurrence.)
  9. Participant has a history of allogeneic cell or organ transplant.

Other protocol defined inclusion/exclusion criteria could apply.

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Arm A
Lifileucel plus Pembrolizumab
Biological: Lifileucel plus Pembrolizumab
A tumor sample is resected from each patient for Lifileucel manufacturing. Patients then receive Pembrolizumab followed by the lifileucel regimen which consists of non-myeloablative lymphodepletion, lifileucel infusion followed by IL-2. Patients will then continue to receive Pembrolizumab every 6 weeks until disease progression.
Other Names:
  • Pembrolizumab
  • LN-144
Active Comparator: Arm B
Pembrolizumab alone with Optional Crossover Period
Biological: Pembrolizumab with Optional Crossover Period

Patient will receive Pembrolizumab monotherapy every 6 weeks until disease progression. Upon verified confirmed disease progression by the blinded independent review central committee, patients may proceed to lifileucel monotherapy during an optional crossover period if they meet eligibility criteria.

Optional crossover: A tumor sample is resected from each patient for Lifileucel manufacturing. Patients then receive the lifileucel regimen which consists of non-myeloablative lymphodepletion, lifileucel infusion followed by IL-2.
