20 mg Selpercatinib
n=42 Participants
Participants were randomized to 1 of 3 treatment sequences and will receive single doses of 20 mg Selpercatinib on each of Days 1, 8, and 15 as either the RTU suspension, the PFOS, or the capsule. Sequence A: Period 1: 20 milligram (mg) Selpercatinib capsule single oral dose administered orally on Day 1. Period 2: 20 mg per milliliter (mL) Selpercatinib Powder for Oral suspension (PFOS) single oral suspension dose on Day 8. Period 3: 20 mg/mL Selpercatinib Ready to Use (RTU) single oral suspension on Day 15. Sequence B: Period 1: 20 mg/mL Selpercatinib RTU single oral suspension on Day 1. Period 2: 20 mg Selpercatinib capsule single oral dose administered orally on Day 8. Period 3: 20 mg/mL PFOS single oral suspension dose on Day 15. Sequence C: Period 1: 20 mg/mL PFOS single oral suspension dose on Day 1. Period 2: 20 mg/mL Selpercatinib RTU single oral suspension on Day 8. Period 3: 20 mg Selpercatinib capsule single oral dose administered orally on Day 15.
