A plain-language read of the study's public EU CTIS listing. The study team confirms the details.
Who can take part
You may be able to join if
- Male/female participants who are at least 18 years of age on the day of signing informed consent with histologically confirmed diagnosis of unresectable or metastatic melanoma will be enrolled in this study.
- Have adequate organ function as defined in the followgin table (Table 3). Specimens must be collected within 10 days prior to the start of study intervention.
- Participants must have measurable disease by investigator assessment according to RECIST v1.1. a). Participants with prior definitive radiation therapy must have measurable disease per RECIST v1.1 that is outside the radiation field or has demonstrated unequivocal progression since completion of radiation therapy.
- A male participant must agree to use a contraception as detailed in Appendix 3 of the protocol during the treatment period and for 9 months after last dose of EV or 4 months after pembrolizumab, whichever occurs last; and refrain from donating sperm during this period.
- A female participant is eligible to participate if she is not pregnant (see Appendix 3), not breastfeeding, and at least one of the following conditions applies: a) Not a woman of childbearing potential (WOCBP) as defined in Appendix 3. OR b) WOCBP should remain on contraception for 12 months after the last dose of EV or 4 months after pembrolizumab, whichever occurs last.
- Participants must have received prior systemic therapy for locally advanced or metastatic melanoma: a) Participants must have progressed on treatment with an anti-PD-1/L1 mAb administered either as monotherapy or in combination with other checkpoint inhibitors or other therapies. PD-1 treatment progression is defined by meeting all of the following criteria: i) Has received at least 2 doses of an approved anti-PD-1/L1 mAb. 1) Has demonstrated disease progression after anti-PD-1/L1 as defined by RECIST v1.1. 2) The initial evidence of PD is to be confirmed by a second assessment no less than 4 weeks from the date of the first documented disease progression, in the absence of rapid clinical progression. ii) Progressive disease / recurrence has been documented within 12 weeks from the last dose of anti-PD-1/L1 mAb. Progressive disease is determined according to iRECIST. This determination is made by the investigator. Once disease progression is confirmed, the initial date of disease progression documentation will be considered the date of disease progression. b) BRAF mutated patients should have received BRAF/MEK inhibitors and PD1/PDL1 therapy. c) Prior CTLA4 therapy is allowed.
You likely can't join if
- A WOCBP who has a positive urine pregnancy test within 72 hours prior to allocation (see Appendix 3). If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
- Has known active CNS metastases and/or carcinomatous meningitis. Note: Participants with previously treated brain metastases may participate provided they are radiologically stable, i.e. without evidence of progression for at least 4 weeks by repeat imaging (note that the repeat imaging should be performed during study screening), clinically stable and without requirement of steroid treatment for at least 14 days prior to first dose of study intervention.
- Has severe hypersensitivity (≥Grade 3) to pembrolizumab and/or any of its excipients. Participants with known severe (≥ Grade 3) hypersensitivity to any enfortumab vedotin excipient contained in the drug formulation of enfortumab vedotin (including histidine, trehalose dihydrate, and polysorbate 20).
- Participants with active keratitis or corneal ulcerations. Participants with superficial punctate keratitis are allowed if the disorder is being adequately treated in the opinion of the investigator.
- Has active autoimmune disease that has required systemic treatment in the past 2 years except replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid)
- Participants with conditions requiring systemic doses of corticosteroids (>10 mg/day of prednisone or equivalent) or other immunosuppressive medications are excluded.

- Participants who have AEs due to previous anticancer therapies must have recovered to ≤Grade 1 or baseline. Participants with endocrine-related AEs who are adequately treated with hormone replacement or participants who have ≤Grade 2 neuropathy are eligible. Note: Patients who had cutaneous adverse events grade 3 or superior are not eligible for the study.
- Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1. Evaluation of ECOG is to be performed within 7 days prior to the first dose of study intervention.
- Provide representative formalin-fixed paraffin-embedded/FFPE paraffin block obtained after last treatment progression. Patients who have no archival tumor tissue after the last treatment progression will be required to provide a fresh biopsy, if the procedure is feasible and safe for the patient. Older archival tumor samples are allowed for patients with no recent archival tissue (after last treatment progression) and not capable of undergoing a new tumor biopsy before the first dose of study treatment. Formalin-fixed, paraffin embedded (FFPE) tissue blocks are preferred to slides.
