Analysis population: PK evaluable population included all participants who received at least one dose of pralsetinib and from whom at least one post dose PK sample was collected. Overall number analyzed is the number of participants with data available for analysis. Number analyzed is the number of participants with data available for analysis at the specified timepoint.

Groups in this outcome

RET- Fusion Positive NSCLC Participants

Participants who had RET-fusion positive NSCLC received pralsetinib, 400 mg orally, QD until discontinuation due to toxicity, disease progression, or other reasons. This arm was specifically planned for reporting PK data.

Tumor-agnostic Participants

Participants who had RET-fusion positive NSCLC or TC, or RET-mutation positive MTC, each with different genetic mutations received pralsetinib, 400 mg orally, QD until discontinuation due to toxicity, disease progression, or other reasons. This arm was specifically planned for reporting PK data.

RET-altered Solid Tumors Participants

Participants who had RET-altered (fusion or mutation) solid tumors previously treated with a selective RET TKI received pralsetinib, 400 mg, orally, QD until discontinuation due to toxicity, disease progression, or other reasons. This arm was specifically planned for reporting PK data.

RET-mutation Positive Tumors Other Than MTC Participants

Participants who had RET-mutation positive solid tumors received Pralsetinib 400 mg, orally, QD until discontinuation due to toxicity, disease progression, or other reasons. This arm was specifically planned for reporting PK data.
