Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Other - favezelimab/pembrolizumab
Treatment: Other - pembrolizumab
Treatment: Drugs - lenvatinib

Experimental: Favezelimab/Pembrolizumab - Participants will receive coformulated favezelimab/pembrolizumab (800 mg/200 mg) via an intravenous (IV) infusion every 3 weeks (Q3W) for 3 cycles in the neoadjuvant period and 14 cycles of adjuvant therapy. Each cycle is 21 days. Participants who do not complete all 3 neoadjuvant cycles should have additional cycles in the adjuvant period so that the total number of study intervention administrations is 17 treatment cycles.

Experimental: Pembrolizumab - Participants will receive 200 mg pembrolizumab via an IV infusion Q3W for 3 cycles in the neoadjuvant period and 14 cycles of adjuvant therapy. Each cycle is 21 days. Participants who do not complete all 3 neoadjuvant cycles should have additional cycles in the adjuvant period so that the total number of study intervention administrations is 17 treatment cycles.

Experimental: Favezelimab/Pembrolizumab + Lenvatinib (Cohort B) - Participants will receive coformulated favezelimab/pembrolizumab (800 mg/200 mg) via IV infusion Q3W for up to 35 cycles (each cycle is 21 days) PLUS lenvatinib every day (QD) 20 mg orally until disease progression, unacceptable toxicity, or discontinuation criteria are met.

Experimental: Pembrolizumab + Lenvatinib (Cohort B) - Participants will receive 200 mg pembrolizumab via IV infusion Q3W for up to 35 cycles (each cycle is 21 days) PLUS lenvatinib QD 20 mg orally until disease progression, unacceptable toxicity, or discontinuation criteria are met.

Summary
Brief summary
The purpose of this study is to evaluate pathologic complete response (pCR) rate of coformulated favezelimab/pembrolizumab (MK-4280A) or pembrolizumab as assessed by blinded central pathology review (BICR) in participants with cutaneous squamous cell carcinoma (cSCC) \[Cohort A\] and to evaluate lenvatinib in combination with coformulated favezelimab/pembrolizumab or pembrolizumab with respect to objective response rate (ORR) per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as assessed by investigator in participants proficient in mismatch repair (pMMR) endometrial cancer (EC) \[Cohort B\].
