A Study of Belzutifan in Adolescent Participants With Solid Tumors (MK-9999-01E/LIGHTBEAM-U01)
LIGHTBEAM-U01 Substudy 01E: A Phase 2 Substudy to Evaluate the Safety and Efficacy of Belzutifan in Participants With Solid Tumors
Researchers are looking for new ways to treat adolescents with locally advanced, unresectable, or metastatic solid tumors. Participants were enrolled into pheochromocytoma/paraganglioma (PPGL), wild type gastrointestinal stromal tumor (wtGIST), and Von Hippel-Lindau (VHL) disease-associated localized tumors cohorts:
- PPGL are rare cancers that start in cells that make hormones in the adrenal glands
- wtGIST is a less common type of cancer that starts in the digestive tract. Wild type means it does not have certain gene mutations (changes)
- VHL disease-associated localized tumors are rare tumors caused by a certain gene mutation that may be passed down from parents to children
- Locally advanced means the cancer has spread into nearby tissue
- Unresectable means the cancer cannot be removed by surgery
- Metastatic means the cancer has spread to other parts of the body
The goal of the study is to learn about the safety of belzutifan and if people tolerate it.

Number of Participants Who Experience One or More Adverse Events (AEs)
Periodo de tiempo: Up to approximately 5 years
|
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.
An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.
The number of participants that experience AEs will be reported.

Up to approximately 5 years

Number of Participants Who Discontinue Study Intervention Due to an AE

Area Under the Concentration-Time Curve From Time 0 to 24 hours of Belzutifan
Periodo de tiempo: At designated timepoints (up to 5 weeks)

Blood samples will be collected at specified intervals to determine the area under the concentration-time curve from time 0 to 24 hours of belzutifan.
|
At designated timepoints (up to 5 weeks)

Minimum Plasma Concentration (Cmin) of Belzutifan
Periodo de tiempo: At designated timepoints (up to 5 weeks)

Blood samples will be collected at specified intervals to determine the Cmin of belzutifan.

Maximum Plasma Concentration (Cmax) of Belzutifan

Objective Response Rate (ORR)
Periodo de tiempo: Up to approximately 5 years
|
ORR is defined as the percentage of participants with Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per Response Evaluation Criteria In Solid Tumors Version 1.1 (RECIST 1.1).
The percentage of participants who experience CR or PR as assessed by investigator will be reported.
|
Up to approximately 5 years
|
|
Duration of Response (DOR)
Periodo de tiempo: Up to approximately 5 years
|
For participants who demonstrate a confirmed Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per Response Evaluation Criteria In Solid Tumors Version 1.1 (RECIST 1.1), DOR is defined as the time from first documented evidence of CR or PR until progressive disease (PD) or death.
Per RECIST 1.1, PD is defined as at least a 20% increase in the sum of diameters of target lesions.
In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.
The appearance of one or more new lesions is also considered PD.
DOR as assessed by investigator will be reported.
