What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cardiodynamics: Placebo-corrected Change From Baseline in QT Interval Corrected Using Fridericia's Correction (QTcF) (ΔΔQTcF) for Treatments A, B, and C

    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

    Measured: Pre-dose, -0.25, -0.5, -0.25, 0.25, 0.5, 0.75, 1.5, 2, 2.5, 3, 4, 7, 9, 12, and 24 hours post-dose

  2. Pharmacokinetics (PK): Area Under the Concentration-time Curve From Time 0 to the Time of the Last Observed Non-zero Concentration (AUC0-t) of Selpercatinib

    Measured: Pre-dose, 0.25, 0.5, 0.75, 1.5, 2, 2.5, 3, 4, 7, 9, 12, 24, 36, 48, 72, 96, 120, 144, 168, 192, 216, and 240 hours postdose

  5. PK: Maximum Observed Concentration (Cmax) of Selpercatinib

    PK: Cmax of Selpercatinib is reported.

    Measured: Pre-dose, 0.25, 0.5, 0.75, 1.5, 2, 2.5, 3, 4, 7, 9, 12, 24, 36, 48, 72, 96, 120, 144, 168, 192, 216, and 240 hours postdose

  6. PK: Time to Reach Cmax (Tmax) of Selpercatinib

    PK: Tmax of Selpercatinib is reported.

    Measured: Pre-dose, 0.25, 0.5, 0.75, 1.5, 2, 2.5, 3, 4, 7, 9, 12, 24, 36, 48, 72, 96, 120, 144, 168, 192, 216, and 240 hours postdose

  7. PK: Apparent First Order Terminal Elimination Rate Constant (Kel) of Selpercatinib

    PK: Kel of Selpercatinib is reported.

    Measured: Pre-dose, 0.25, 0.5, 0.75, 1.5, 2, 2.5, 3, 4, 7, 9, 12, 24, 36, 48, 72, 96, 120, 144, 168, 192, 216, and 240 hours postdose

    PK: t½ of Selpercatinib is reported.

    Measured: Pre-dose, 0.25, 0.5, 0.75, 1.5, 2, 2.5, 3, 4, 7, 9, 12, 24, 36, 48, 72, 96, 120, 144, 168, 192, 216, and 240 hours postdose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Selpercatinib and Moxifloxacin in people with Healthy, run by Eli Lilly and Company at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Sep 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cardiodynamics: Placebo-corrected Change From Baseline in QT Interval Corrected Using Fridericia's Correction (QTcF) (ΔΔQTcF) for Treatments A, B, and C (time frame: Pre-dose, -0.25, -0.5, -0.25, 0.25, 0.5, 0.75, 1.5, 2, 2.5, 3, 4, 7, 9, 12, and 24 hours post-dose). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Sep 2025; AzTrials last refreshed its copy on 8 Nov 2026.
