Study summary

The main purpose of this study is to determine how safe and how well tolerated selpercatinib is when given as oral doses to healthy participants. The study will also assess how fast selpercatinib gets into the blood stream and how long it takes the body to remove it. The study will last up to about 6 weeks, inclusive of screening period.

What researchers measure

Primary outcomes

  1. Number of Participants with One or More Serious Adverse Event(s) (SAEs) Considered by the Investigator to be Related to Study Drug Administration

    A summary of SAEs and other non-serious adverse events (AEs), regardless of causality, will be reported in the Reported Adverse Events module

    Time frame: Baseline through Day 8

Secondary outcomes

  1. Pharmacokinetics (PK): Area under the concentration-time curve, from time 0 to the last observed non-zero concentration (AUC0-t) of Selpercatinib

    PK: AUC0-t of Selpercatinib

    Time frame: Pre-dose up to 168 hour post-dose

  2. PK: Area under the concentration-time curve, from time 0 to Hour 24 (AUC0-24) of Selpercatinib

    PK: AUC0-24 of Selpercatinib

    Time frame: Pre-dose up to 168 hour post-dose

  3. PK: Area under the concentration-time curve from time 0 extrapolated to infinity (AUC0-inf) of Selpercatinib

    PK: AUC0-inf of Selpercatinib

    Time frame: Pre-dose up to 168 hour post-dose

  4. PK: Percent of AUC0-inf extrapolated (AUC%extrap) of Selpercatinib

    PK: AUC%extrap of Selpercatinib

    Time frame: Pre-dose up to 168 hour post-dose

  5. PK: Apparent total plasma clearance after oral (extravascular) administration (CL/F) of Selpercatinib

    PK: CL/F of Selpercatinib

    Time frame: Pre-dose up to 168 hour post-dose

  6. PK: Maximum observed concentration (Cmax) of Selpercatinib

    PK: Cmax of Selpercatinib

    Time frame: Pre-dose up to 168 hour post-dose

  7. PK: Time to reach Cmax (Tmax) of Selpercatinib

    PK: Tmax of Selpercatinib

    Time frame: Pre-dose up to 168 hour post-dose

  8. PK: Apparent first-order terminal elimination rate constant (Kel) of Selpercatinib

    PK: Kel of Selpercatinib

    Time frame: Pre-dose up to 168 hour post-dose

  9. PK: Apparent volume of distribution during the terminal elimination phase (Vz/F) of Selpercatinib

    PK: Vz/F of Selpercatinib

    Time frame: Pre-dose up to 168 hour post-dose
