May 8, 2026 updated by: Merck Sharp & Dohme LLC

A Phase 3, Randomized, Open-label Study of Belzutifan + Zanzalintinib Versus Cabozantinib in Participants With Advanced RCC Who Experienced Disease Recurrence During or After Prior Adjuvant Anti-PD-1/L1 Therapy (LITESPARK-033)

Researchers are looking for more ways to treat advanced renal cell carcinoma (RCC) that is recurrent. Researchers want to learn if recurrent advanced renal cell carcinoma (RCC) responds (gets smaller or goes away) after treatment with belzutifan (MK-6482) and zanzalintinib compared to cabozantinib.

The goal of this study is to learn if:

People who take belzutifan and zanzalintinib live longer overall and without the cancer getting worse than people who take cabozantinib.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Progression Free Survival (PFS)
Time Frame: Up to approximately 73 months
PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first. PD will be assessed by Response Criteria in Solid Tumors Version 1.1 (RECIST 1.1). PD is defined as ≥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 ≥5 mm. The appearance of one or more new lesions is also considered PD. PFS as assessed by blinded independent central review (BICR) will be presented.
Up to approximately 73 months
Overall Survival (OS)
Time Frame: Up to approximately 73 months
OS is defined as the time from randomization to death due to any cause.
Up to approximately 73 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Objective Response Rate (ORR)
Time Frame: Up to approximately 73 months
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 Blinded Independent Central Review (BICR) will be presented.
Up to approximately 73 months
Duration of Response (DOR)
Time Frame: Up to approximately 73 months
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 Blinded Independent Central Review (BICR) will be presented.
Up to approximately 73 months
Number of Participants Who Experience One or More Adverse Events (AEs)
Time Frame: Up to approximately 73 months
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 who experienced an AE will be reported.
Up to approximately 73 months
Number of Participants Who Discontinue Study Treatment due to an AE
Time Frame: Up to approximately 73 months
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 who discontinue the study treatment due to an AE will be reported.
Up to approximately 73 months
Change From Baseline in European Organisation for the Research and Treatment of Cancer Quality of Life Questionnaire 30 (EORTC QLQ-C30) Global Health/Health-Related Quality of Life (HRQoL) Items 29 and 30 Combined Score
Time Frame: Up to approximately 25 months
The EORTC QLQ-C30 is a cancer specific health-related quality-of life (QoL) questionnaire. Participant responses to the questions regarding Global Health Status (GHS; "How would you rate your overall health during the past week?") and Quality of Life (QoL; "How would you rate your overall quality of life during the past week?") are scored on a 7-point scale (1= Very poor to 7=Excellent), then summed. Summed raw scores are standardized by linear transformation so that scores ranged from 0 to 100, with a higher score indicating a better overall outcome.
Up to approximately 25 months
Change From Baseline in EORTC QLC-C30 Physical Functioning Items 1-5 Score
Time Frame: Up to approximately 25 months
The EORTC QLQ-C30 is a cancer specific health-related quality-of life (QoL) questionnaire. Participant responses to 5 questions about their physical functioning (Items 1-5) are scored on a 4-point scale (1=Not at All to 4=Very Much). The combined score of items 1 to 5 was computed by averaging the raw scores of the 5 items and then applying a linear transformation to standardize the average score, so that the combined scores range from 0-100. A higher score indicates a better outcome.
Up to approximately 25 months
Change From Baseline in EORTC QLQ-C30 Role Functioning Items 6-7 Score
Time Frame: Up to approximately 25 months
The EORTC QLQ-C30 is a questionnaire to assess the overall quality of life of cancer patients. Participant responses to 2 questions about their role functioning are scored on a 4-point scale (1=Not at All to 4=Very Much). Summed raw scores are standardized by linear transformation so that scores ranged from 0 to 100, with a higher score indicating a better level of functioning.
Up to approximately 25 months
Change From Baseline in Functional Assessment of Cancer Therapy-Kidney Symptom Index-Disease-related Symptoms (FKSI-DRS) Items 1-9 Score
Time Frame: Up to approximately 25 months
The FKSI-DRS index consists of a 9-item questionnaire that assesses the extent of participant symptoms from kidney cancer. Responses are scored on a 5-point scale (0=Not at all to 4=Very much) and summed to generate an index symptom score. These scores can range from 0 to 36, with a higher score indicating more favorable kidney cancer symptom status.
Up to approximately 25 months
Time From Baseline to First Deterioration in EORTC-QLC-C30 Global Health/HRQoL Score
Time Frame: Up to approximately 25 months
Time to True Deterioration (TTD) is defined as the time from baseline to the first onset of a ≥10-point decrease with confirmation by the subsequent visit of a ≥10-point decrease in Items 29 and 30 scale scores. A longer TTD indicates a better outcome. TTD is reported based on the product-limit (Kaplan-Meier) method for censored data.
Up to approximately 25 months
Time From Baseline to First Deterioration in EORTC-QLC-C30 Physical Functioning Score
Time Frame: Up to approximately 25 months
TTD is defined as the time from baseline to the first onset of a ≥10-point deterioration (decrease) from baseline in physical functioning score (EORTC QLQ-C30 Items 1-5). Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The TTD, as assessed based on a ≥10-point negative change (decrease) from baseline in physical functioning score will be presented. A longer TTD indicates a better outcome.
Up to approximately 25 months
Time From Baseline to First Deterioration in EORTC-QLC-C30 Role Functioning Score
Time Frame: Up to approximately 25 months
TTD is defined as the time from baseline to the first onset of a ≥10-point negative change (decrease) from baseline in role functioning (EORTC QLQ-C30 Items 6 and 7) score. Using linear transformation, raw scores are standardized, so that scores range from 0 to 100. The TTD, as assessed based on a ≥10 point negative change (decrease) from baseline in role functioning score, will be presented. A longer TTD indicates a better outcome.
Up to approximately 25 months
Time From Baseline to First Deterioration in FKSI-DRS Score
Time Frame: Up to approximately 25 months
TTD is defined as time from the first dose of study treatment to the date of deterioration of FKSI-DRS Score. Each item is scored on a 5-point scale (0=not at all to 4=very much). FKSI-DRS total score ranged from 0 (most severe symptoms) to 36 (no symptoms) with a higher score indicating a better outcome. Deterioration is defined as a 3-point decrease (i.e. lower score) in symptom score and the time to true deterioration is the time to first onset of 3 or more decreases from baseline with confirmation under right-censoring rule (the last observation). A longer TTD indicates a better outcome.
