Experimental: Arm A (Pralsetinib)
Participants will receive pralsetinib at a dose of 400 milligrams (mg) orally once daily (PO QD) in 28-day cycles.
Participants will receive pralsetinib at a dose of 400 mg, as per the dosing schedule described above.
Active Comparator: Arm B (SOC: Cabozantinib/Vandetanib)
Adult participants will receive investigator's choice of SOC MKI therapy with either 140 mg cabozantinib PO QD or 300 mg vandetanib PO QD in 28-day cycles. Adolescents participants (≥ 12 and < 18 years of age) will receive vandetanib, PO QD or every other day, in 28-day cycles depending on the body surface area (BSA), at a dose determined according to the dosing nomogram available in the E.U. Vandetanib SmPC.
Adult participants will receive cabozantinib at a dose of 140 mg, as per the dosing schedule described above.
Adult participants will receive vandetanib at a dose of 300 mg and adolescent participants will receive vandetanib as per the dosing schedule described above.
- Progression-Free Survival (PFS) [ Time Frame: Up to 5 years ]Defined as the time from randomization date to the first documented PD (Progression of Disease), as assessed by BICR according to Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1) or death due to any cause, whichever occurs first.
- Time-To-Treatment Failure (TTF) [ Time Frame: Up to 13 years ]Defined as the time from randomization date to the discontinuation of study drug during the treatment period due to death, treatment-related adverse event, or PD, as assessed by BICR according to RECIST v1.1, whichever occurs first.
- Objective Response Rate (ORR) [ Time Frame: Up to 13 years ]Defined as the proportion of participants who achieve a CR (Complete Response) or a PR (Partial Response) prior to progressive disease and/or other anti-cancer therapy, as assessed by BICR according to RECIST v1.1.
- Overall Survival (OS) [ Time Frame: Up to 13 years ]Defined as the time from randomization date to death due to any cause.
- Percentage of Participants With Adverse Events (AEs) [ Time Frame: Up to 13 years ]Incidence and severity determined according to the NCI CTCAE v5.0 (National Cancer Institute Common Terminology Criteria for Adverse Events, Version 5.0) criteria.
- Duration of Response (DOR) [ Time Frame: Up to 13 years ]Defined as the number of weeks from the time criteria are first met for either a CR or a PR, until the date of documented PD, as assessed by BICR according to RECIST v1.1, or death due to any cause, whichever occurs first.
- Disease Control Rate (DCR) [ Time Frame: Up to 13 years ]Defined as the proportion of participants who experience a best response of CR, PR, or stable disease, as assessed by BICR according to RECIST v1.1.
- Clinical Benefit Rate (CBR) [ Time Frame: Up to 13 years ]Defined as the proportion of participants who experience a CR or a PR or a best response of stable disease with a minimum duration of 6 months, as assessed by BICR according to RECIST v1.1.
- Time to Deterioration of Function [ Time Frame: Up to 13 years ]Defined as the time from randomization to the date of a participant's first >= 10-point decrease from baseline score, as assessed through the use of the European Organisation for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30).
- Quality of Life (QoL) [ Time Frame: Up to 13 years ]Defined as the time from randomization to the date of a participant's first >= 10-point decrease from baseline score, as assessed through the use of the GHS (Global Health Status)/QoL scales.
- Acceptability and Palatability of Pralsetinib Capsules [ Time Frame: Up to 13 years ]Acceptability Survey scores on Day 1 of Cycle 1 and Crossover Cycle 1 (each cycle is 28 days).
