A Study to Investigate the Efficacy and Safety of an Infusion of IOV-4001 in Adult Participants With Unresectable or Metastatic Melanoma or Stage III or IV Non-small-cell Lung Cancer (NCT05361174) is a Phase 1 / Phase 2 interventional studying Unresectable Melanoma and Metastatic Melanoma, sponsored by Iovance Biotherapeutics, Inc.. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

This is a study to investigate the efficacy and safety of an infusion of IOV-4001 in adult participants with unresectable or metastatic melanoma or advanced non-small-cell lung cancer (NSCLC).

What Stage of Research Is This?

Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Unresectable Melanoma, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 53 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Unresectable Melanoma subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Participants who have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. 4. Participants who is assessed as having at least one resectable lesion. 5. Participants who have at least one measurable lesion, following resection of the lesion for IOV-4001 generation. 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 during treatment and up to 12 months. 10. Participants who are \>70 years of age may be allowed to enroll after the investigator discusses with the medical monitor. Who Should NOT Join This Trial: 1. Participants who have melanoma of uveal/ocular origin. 2. Participants who have symptomatic untreated brain metastases. 3. Participants who have had a history of allogeneic organ transplant or any form of cell therapy involving prior conditioning chemotherapy within the past 20 years. ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.

Treatments Being Tested

BIOLOGICAL

IOV-4001

A tumor sample is resected from each participant and cultured ex-vivo to manufacture IOV-4001. After lymphodepleting chemotherapy including cyclophosphamide and fludarabine, participant is infused with IOV-4001, and followed by IL-2.
