Supercharged immune cells take on advanced melanoma in major new trial
NCT ID NCT05727904
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Phase 3 trial is testing whether a powerful combination of two treatments works better than standard immunotherapy alone for people with advanced melanoma that has not been treated yet. The experimental approach uses lifileucel, a personalized therapy made from a patient's own tumor-fighting immune cells, given together with the immunotherapy drug pembrolizumab. About 670 participants will be randomly assigned to receive either the combination or pembrolizumab alone, with the goal of seeing which group has better tumor shrinkage and longer time without cancer growth.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lifileucel (a personalized cell therapy made from a patient's own tumor-fighting immune cells) plus pembrolizumab (an immunotherapy drug)
- What this could lead to
- If successful, this combination could offer a more effective first-line treatment for advanced melanoma, potentially shrinking tumors and delaying progression better than standard immunotherapy alone.
- What could go wrong
- This is an early Phase 3 trial, so results are not yet proven. The cell therapy requires surgery and a complex manufacturing process, and side effects from lymphodepletion and IL-2 can be severe. Not all patients may benefit.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
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.
