Trial Purpose

This is a two-part study of pembrolizumab (MK-3475) in pediatric participants who have any of the following types of cancer:

  • advanced melanoma (6 months to <18 years of age),
  • advanced, relapsed or refractory programmed death-ligand 1 (PD-L1)-positive malignant solid tumor or other lymphoma (6 months to <18 years of age),
  • relapsed or refractory classical Hodgkin lymphoma (rrcHL) (3 years to <18 years of age), or
  • advanced relapsed or refractory microsatellite-instability-high (MSI-H) solid tumors (6 months to <18 years of age), or
  • advanced relapsed or refractory tumor-mutational burden-high ≥10 mutation/Mb (TMB-H) solid tumors (6 months to <18 years of age)
  • with adjuvant treatment of resected high-risk Stage IIB, IIC, III, or IV melanoma in children 12 years to <18 years of age

Part 1 will find the maximum tolerated dose (MTD)/maximum administered dose (MAD), confirm the dose, and find the recommended Phase 2 dose (RP2D) for pembrolizumab therapy. Part 2 will further evaluate the safety and efficacy at the pediatric RP2D.

The primary hypothesis of this study is that intravenous (IV) administration of pembrolizumab to children with either advanced melanoma; a PD-L1 positive advanced, relapsed or refractory solid tumor or other lymphoma; advanced, relapsed or refractory MSI-H solid tumor; or rrcHL, will result in an Objective Response Rate (ORR) greater than 10% for at least one of these types of cancer. The 10% assessment does not apply to the MSI-H and TMB-H cohorts.

With Amendment 8, enrollment of participants with solid tumors and of participants aged 6 months to <12 years with melanoma were closed. Enrollment of participants aged ≥12 years to ≤18 years with melanoma continues. Enrollment of participants with MSI-H and TMB-H solid tumors also continues.

About the trial

Trial phase Icon Current trial phase

Trial Phase 1

Investigational medication is tested for safety on a relatively small group of 20 to 100 volunteers who are usually healthy, but not always. Phase 1 trials may happen in a doctor’s office or a hospital.

Trial Phase 2

In Phase 2 trials, researchers try to find out if a treatment works in about 100 to 500 participants – usually people who have the health condition the treatment is intended to treat. In vaccine trials, the participants are usually healthy. Phase 2 trials may happen in a doctor’s office, a clinic, or a hospital.
