Description of intervention(s) / exposure
Treatment: Drugs - Pralsetinib
Treatment: Drugs - Cabozantinib
Treatment: Drugs - Vandetanib

Experimental: Arm A (Pralsetinib) - Participants will receive pralsetinib at a dose of 400 milligrams (mg) orally once daily (PO QD) in 28-day cycles.

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.


Treatment: Drugs: Pralsetinib
Participants will receive pralsetinib at a dose of 400 mg, as per the dosing schedule described above.

Treatment: Drugs: Cabozantinib
Adult participants will receive cabozantinib at a dose of 140 mg, as per the dosing schedule described above.

Treatment: Drugs: Vandetanib
Adult participants will receive vandetanib at a dose of 300 mg and adolescent participants will receive vandetanib as per the dosing schedule described above.
