A Study of Pembrolizumab (MK-3475) in Pediatric Participants With an Advanced Solid Tumor or Lymphoma (MK-3475-051/KEYNOTE-051)
United States, Brazil, France370 participantsStarted 2015-03-19
Plain-language summary
Researchers are looking for new ways to treat children with different types of melanoma (skin cancer), solid tumors, and lymphomas (blood cancers) that are any of these:
* Advanced, which means cancer spread in the body or cannot be removed with surgery
* Relapsed, which means cancer has come back after it had responded to previous treatment (responded means it stopped growing, gets smaller, or disappeared)
* Refractory, which means cancer did not respond to previous treatment
Pembrolizumab is an immunotherapy, which is a treatment that helps the immune system fight cancer. Researchers want to learn if different doses of pembrolizumab can cause at least 1 of the types of cancer to get smaller or go away.
With Amendment 8, enrollment of participants with solid tumors and participants 6 months to under 12 years old with melanoma were closed.
With Amendment 13, enrollment was closed for participants with relapsed refractory classical Hodgkin lymphoma (rrCHL), microsatellite instabilty-high (MSI-H) solid tumors, tumor-mutational burden-high (TMB-H) solid tumors, and participants 12 years old to \<18 years old with advanced melanoma.

Inclusion Criteria:
* Between 6 months and \<18 years of age on day of signing informed consent is documented.
* Histologically- or cytologically-documented, locally-advanced, or metastatic solid malignancy or lymphoma that is incurable and has failed prior standard therapy, or for which no standard therapy exists, or for which no standard therapy is considered appropriate
* Any number of prior treatment regimens
* Tissue (or lymph node biopsy for rrcHL participants) available from an archival tissue sample or, if appropriate, a newly obtained core or excisional biopsy of a tumor lesion not previously irradiated
* Advanced melanoma or PD-L1-positive advanced, relapsed, or refractory solid tumor or lymphoma
* Measurable disease based on RECIST 1.1 (Or based on IWG \[Cheson, 2007\] \[i.e., measurement must be \>15 mm in longest diameter or \>10 mm in short axis\] for rrcHL participants)
* Participants with neuroblastoma with only metaiodobenzylguanidine (MIBG)-positive evaluable disease may be enrolled

* Adequate organ function
* Female participants of childbearing potential should have a negative urine or serum pregnancy test within 72 hours before the first dose of study medication
* Female participant is not a woman of childbearing potential (WOCBP) or is a WOCBP who is abstinent from heterosexual intercourse or using contrace…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
