What was measured

ORR: Percentage of participants who achieve best overall response Complete Response (CR) or Partial Response (PR) per Response Evaluation Criteria in Solid Tumors (RECIST). * CR is defined as disappearance of all target lesions. * PR is defined as at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD.

Analysis population: All participants who received at least one dose of study drug.

Groups in this outcome

Cohort 1 (Phase 2): MTC Group

Participants in this cohort had MTC and received 92mg/m\^2 (maximum160 mg BID) of selpercatinib BID orally on Days 1 through 28 of a 28-day cycle. The treatment was continued until participants experienced a progressive disease, unacceptable toxicity, or other protocol-defined reason for discontinuation.

Cohort 2 (Phase 2): PTC Group

Participants in this cohort had PTC and received 92mg/m\^2 (maximum160 mg BID) of selpercatinib BID orally on Days 1 through 28 of a 28-day cycle. The treatment was continued until participants experienced a progressive disease, unacceptable toxicity, or other protocol-defined reason for discontinuation.

Cohort 3 (Phase 2): Other Cancer Group

Participants in this cohort had other (RET-altered non-thyroid) cancer and received 92mg/m\^2 (maximum160 mg BID) of selpercatinib BID orally on Days 1 through 28 of a 28-day cycle. The treatment was continued until participants experienced a progressive disease, unacceptable toxicity, or other protocol-defined reason for discontinuation.
