Brief summary
The main purpose of this study is to assess the effect of Pirtobrutinib (LOXO-305) on the heart rate-corrected QT (QTc) interval and to conduct blood tests to measure how much pirtobrutinib (LOXO-305) is in the bloodstream and how the body handles and eliminates pirtobrutinib. The study will also evaluate the safety and tolerability of pirtobrutinib. The study will last up to 71 days, including screening.

Outcome results
Placebo-corrected Change From Baseline in QT Interval Corrected Using Fridericia's Correction (QTcF) (ΔΔQTcF)
The cardiodynamic assessment was performed through 12-lead electrocardiogram (ECG) extracted from continuous recordings at pre-specified time points. Participants rested in supine position for at least 10 minutes prior to and 5 minutes after each time point for ECG extractions. The QT interval is the time from electrocardiogram Q wave to the end of the T wave corresponding to electrical systole. QT interval was corrected for heart rate using QTcF. Placebo-corrected change from baseline in QTcF (ΔΔQTcF) was calculated based on model-predicted effect.
Time frame: Baseline (Predose), 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 6, 8.5, 12 and 24 hours post-dose
Population: Pharmacokinetic/Corrected QT interval (PK/QTc) population included all participants who were in both the PK and QT/QTc populations with at least 1 pair of post-dose PK and ΔQTc data from the same time point in at least 1 period as well as participants in the QT/QTc population who received placebo. As per planned analysis, data was planned to be reported only for Treatment A (900 mg pirtobrutinib) concentration for this outcome measure.

Change From Baseline in Heart Rate (ΔHR)
Heart rate is the number of times the ventricles of the heart contract and relax per minute. Change from baseline in heart rate (ΔHR) was calculated using linear mixed-effects model analysis.

Population: QT/QTc population included all participants who received 1 dose of study drug with measurements at baseline as well as on treatment with at least 1 post-dose time point with a valid ΔQTc value. Here, 'Number Analyzed' signifies participants who were evaluable at specific timepoints. As per planned analysis, data was planned to be reported only for Treatment A and B for this outcome measure.

The QT interval is the time from electrocardiogram Q wave to the end of the T wave corresponding to electrical systole. QT interval was corrected for heart rate using QTcS.
Time frame: Baseline (predose), 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 6, 8.5, 12 and 24 hours post-dose
Population: QT/QTc population included all participants who received 1 dose of study drug with measurements at baseline as well as on treatment with at least 1 post-dose time point with a valid ΔQTc value. As per planned analysis, data was planned to be reported only for Treatment A and B for this outcome measure.

Placebo-corrected Change From Baseline in ΔQTcF (ΔΔQTcF), If a Substantial Heart Rate Effect Was Observed
The cardiodynamic assessment was performed through 12-lead ECG extracted from continuous recordings at pre-specified time points. Participants rested in supine position for at least 10 minutes prior to and 5 minutes after each time point for ECG extractions. The QT interval is the time from electrocardiogram Q wave to the end of the T wave corresponding to electrical systole. QT interval was corrected for heart rate using QTcF.
Time frame: Baseline (predose), 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 6, 8.5, 12 and 24 hours post-dose
Population: PK/QTc population included all participants who were in both the PK and QT/QTc populations with at least 1 pair of post-dose PK and ΔQTc data from the same time point in at least 1 period as well as participants in the QT/QTc population who received placebo. As per planned analysis, data was planned to be reported only for Treatment A and B for this outcome measure.
