A Study of Pembrolizumab (MK-3475) in Pediatric Participants With an Advanced Solid Tumor or Lymphoma (MK-3475-051/KEYNOTE-051)

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) 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.

Intensity-Modulated or Proton Radiation Therapy for Sinonasal Malignancy

The purpose of this study is to test the hypothesis that 1)intensity-modulated radiotherapy (IMRT) or proton radiation therapy would result in improved local control rate and lowered toxicity compared to conventional radiotherapy, and 2) proton radiation therapy would result in equivalent or improved local control rate with similar or lower toxicity compared to IMRT, in the treatment of locally advanced sinonasal malignancy. Data from retrospective studies suggest that IMRT or proton radiation therapy resulted in promising outcome in patients with sinonasal malignancy. To this date, no prospective study has been conducted to evaluate the outcome of sinonasal cancer treated with IMRT or proton radiation therapy. This Phase II trial is the first prospective study conducted to determine the treatment outcome and toxicity of IMRT or proton in the treatment of sinonasal cancer. IMRT and proton radiation therapy are the two most established and most commonly employed advanced radiotherapy techniques for the treatment of sinonasal cancer. It is highly controversial whether one is superior to the other in terms of local control and toxicity outcome. It is also not clear if a subset of patients would benefit more from one treatment technology versus the other. Due to the rarity and heterogeneity of sinonasal malignancies and the fact that proton beam is only available at a few centers in the United States, it is not feasible at present to do a Phase III study randomizing patients between IMRT and proton radiation therapy. In this study, a planned secondary analysis will be performed, comparing the treatment and toxicity outcome between IMRT and proton. The data on the IMRT and proton comparison from this trial will be used to design future multi-center prospective trials and to determine if randomized trial is necessary. In this study, the treatment technique employed for an individual case will not be determined by the treating physician(s), but rather by the most advanced technology available at the treating institution for the treatment of the sinonasal cancer. At the Massachusetts General Hospital (MGH), proton beam therapy will be used for patients who meet the eligibility criteria. For institutions where protons are not available or institutions where the proton planning systems have not been optimized, IMRT exclusively will be used for the treatment of sinonasal cancer. Patient and tumor characteristics are expected to be comparable between IMRT- and proton- institutions
