Primary Outcome Measures
NameTimeMethod
Area Under the Curve From Time Zero to Extrapolated Infinite Time (AUCinf) of Lotiglipron When Administered Alone and With Itraconazole or CyclosporinePre-dose of lotiglipron and at 0.5, 1, 2, 4, 6, 8, 10, 12, 14, 24, 36, 48, 72, 96, 120, and 144 (for Period 3 only) hours post dose of lotiglipron on Day 1 of Periods 1 and 2 and on Day 4 of Period 3.

AUCinf is area under the plasma concentration-time profile from time zero extrapolated to infinite time. AUCinf is caluculated by AUClast + (Clast/kel), where Clast is the predicted plasma concentration at the last quantifiable time point estimated from the log-linear regression analysis.

Secondary Outcome Measures
NameTimeMethod
Number of Participants With Treatment-Emergent Adverse Events (TEAEs)From the first dose up to 35 days after administration of the final dose of study intervention (Period 3 Day 9, Study Day 19), the maximum duration was 54 Days

An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. A serious adverse event (SAE) was defined as an AE: 1. resulting in death, 2. was life-threatening, 3. required inpatient hospitalization or prolongation of existing hospitalization, 4. resulted in persistent disability, 5. was a congenital anomaly/birth defect, or considered to be an important medical event. Any AEs occurring following start of treatment were considered as treatment emergent adverse event (TEAE). Events that occur during follow-up within the lag time of up to 35 days after the last dose of study intervention were counted as treatment emergent and attributed to the last treatment taken.

Number of Participants With Laboratory AbnormalitiesBaseline (pre-dose on Day 1), Period 2 Day 5 (Study Day 10), and Period 3 Day 10 (Study Day 20)

Participants with laboratory abnormalities (without regard to baseline abnormality) that met pre-specified criteria: For HEMATOLOGY, 1) Erythrocyte (Ery.) Mean Corpuscular Volume (fL) \< 0.9\*Lower limit of normal (LLN), 2) Ery. Mean Corpuscular Hemoglobin (picograms \[pg\]/cell) \< 0.9\*LLN; 3) Eosinophils/Leukocytes (%)\> 1.2\*upper limit of normal (ULN); for CLINICAL CHEMISTRY, Urate (mg/dL)\> 1.2\*ULN; for URINALYSIS, Urine Hemoglobin (Scalar)≥ 1.

Number of Participants Meeting Pre-Specified Criteria of Vital SignsPre-dose Day 1 in periods 1, 2 and 3 (Study Days 1, 6, and 11, respectively), and prior to discharge on Period 3 Day 10 (Study Day 20)

Pre-specified criteria of vital signs included: Supine diastolic blood pressure (BP) \<50mmHg, change from baseline maximum (max) decrease or increase \>=20mmHg; supine pulse rate min\< 40 beats per minute (bpm), max\> 120 bpm; Supine systolic BP: Value \<90 mmHg, change from baseline max decrease or increase \>=30mmHg

Change From Baseline in Body Weight at the End of Periods 1, 2, and 3Baseline (pre-dose on Day 1), Day 5 of Period 1 (Study Day 5), Day 5 of Period 2 (Study Day 10), and Day 10 of Period 3 (Study Day 20)

Observed value at baseline and change from baseline in body weight at Day 5 of Period 1 , Day 5 of Period 2, and Day 10 of Period 3 were summarized.

Number of Participants Meeting Pre-Specified Criteria of Electrocardiogram (ECGs)Pre-dose Day 1 in periods 1, 2 and 3 (Study Days 1, 6, and 11, respectively), and prior to discharge on Period 3 Day 10 (Study Day 20)

The pre-specified criteria of ECG included: QT interval, aggregated: value \>500 millisecond (msec); corrected QT Fridericia method (QTCF) interval, aggregated: 450\<=value\<480 msec, 480\<=value\<500 msec, value\>=500 msec, 30\<=changes\<60msec, and changes\>=60msec.

Number of Participants With Suicidal Ideation or Behavior According to Columbia Suicide Severity Rating Scale (C-SSRS)Period 1 Day -1 (Study Day -1), Period 3 Day 10 (Study Day 20) or Early Termination visit

The C-SSRS is an interview-based rating scale to systematically assess suicidal ideation and suicidal behavior. Participants who respond "yes" to any question related to suicidal ideation or behavioral are reported in this outcome measure.

Number of Participants With a Score of ≥15 on Patient Health Questionnaire-9 (PHQ-9)Period 1 Day -1 (Study Day -1), Period 3 Day 10 (Study Day 20) or Early Termination visit

PHQ9-9 is a 9 item self-report scale for the assessment of depressive symptoms. A PHQ-9 score of ≥15 indicates clinically significant depression and was reported in this outcome measure. The total score ranges from 0 to 27 with the following interpretation: Score 1-4: minimal depression; Score 5-9: Mild depression; Score 10-14: moderate depression; Score 15-19 moderately severe depression; Score 20-27: Severe depression

Maximum Observed Plasma Concentration (Cmax) of Lotiglipron When Administered Alone and With Itraconazole or CyclosporinePre-dose of lotiglipron and at 0.5, 1, 2, 4, 6, 8, 10, 12, 14, 24, 36, 48, 72, 96, 120, and 144 (for Period 3 only) hours post dose of lotiglipron on Day 1 of Periods 1 and 2 and on Day 4 of Period 3.

Cmax is the maximum observed concentration and is observed directly from data.

CL/F is the apparent oral clearance and is calculated by Dose/AUCinf.

Apparent Oral Volume of Distribution (Vz/F) of Lotiglipron When Administered Alone and With Itraconazole or CyclosporinePre-dose of lotiglipron and at 0.5, 1, 2, 4, 6, 8, 10, 12, 14, 24, 36, 48, 72, 96, 120, and 144 (for Period 3 only) hours post dose of lotiglipron on Day 1 of Periods 1 and 2 and on Day 4 of Period 3.

Vz/F is the apparent volume of distribution and is calculated by Dose/ (AUCinf\*kel), where kel is the terminal phase rate constant calculated by a linear regression of the log linear concentration time curve

Terminal Half-life (t1/2) of Lotiglipron When Administered Alone and With Itraconazole or CyclosporinePre-dose of lotiglipron and at 0.5, 1, 2, 4, 6, 8, 10, 12, 14, 24, 36, 48, 72, 96, 120, and 144 (for Period 3 only) hours post dose of lotiglipron on Day 1 of Periods 1 and 2 and on Day 4 of Period 3.

T1/2 is calculated by Loge(2)/kel, where kel is the terminal phase rate constant calculated by a linear regression of the log linear concentration time curve. Only those data points judged to describe the terminal log linear decline were used in the regression.
