A Study of Soticlestat With Itraconazole and Mefenamic Acid in Healthy Adults
Study Details
Study Description
Brief Summary
The main aim of this study is to check how itraconazole and mefenamic acid affect the way soticlestat is processed by the body.
The study will have 2 parts. Participants can only participate in one study part.
Part 1: Participants will check into the study clinic to receive soticlestat, four days later they will begin receiving itraconazole and will stay in the clinic for 11 more days, receiving soticlestat in combination with itraconazole on one of those days. Participants will be contacted about 8 days after leaving the clinic for follow-up.
Part 2: Participants will check into the study clinic to receive soticlestat, four days later they will begin receiving mefenamic acid and will stay in the clinic for 7 more days, receiving soticlestat in combination with mefenamic acid on one of those days.. Participants will be contacted about 9 days after leaving the clinic for follow-up.

Phase 1 |
Detailed Description
The drug being tested in this study is called soticlestat (TAK-935). The study will evaluate the safety and tolerability of soticlestat when co-administered with either itraconazole or mefenamic acid in healthy participants.
The study will be conducted in 2 parts: Part 1 (drug-drug interaction [DDI] with itraconazole), Part 2 (DDI with mefenamic acid). The study will enroll approximately 28 participants. Participants will be enrolled into two parts (Part 1 and Part 2) to receive soticlestat along with adjunctive therapy itraconazole and mefenamic acid as:
-
Part 1: Soticlestat 300 mg + Itraconazole 200 mg
-
Part 2: Soticlestat 300 mg + Mefenamic Acid 500 mg (first dose only) and 250 mg (subsequent doses)
Both Parts 1 and 2 will have two period (Periods 1 and 2). In Period 1, participants will receive only soticlestat (study drug) and in Period 2, participants will receive study drug along with either itraconazole or mefenamic acid depending upon in which part they are in. The data will be collected and stored in electronic case report form (eCRF).
This single-center trial will be conducted in the United States. The overall duration of the study is approximately 52 days for participants in Part 1 (includes screening and follow-up), but 48 days for participants in Part 2 (including screening and follow-up). There will be follow up for all participants approximately 15 days after the last dose of soticlestat in each study part.

Outcome Measures
Primary Outcome Measures
- Parts 1 and 2: Cmax: Maximum Observed Plasma Concentration for Soticlestat [Parts 1, 2 (Period 1):Day 1 predose and multiple timepoints (up to 96 hours) postdose;Part 1 (Period 2) Day 5 predose and multiple timepoints (up to 168 hours) postdose; Part 2 (Period 2) Day 2 predose and multiple timepoints (up to 144 hours) postdose]
- Parts 1 and 2: AUC∞: Area Under the Plasma Concentration-time Curve from Time 0 to Infinity for Soticlestat [Parts 1, 2 (Period 1):Day 1 predose and multiple timepoints (up to 96 hours) postdose;Part 1 (Period 2) Day 5 predose and multiple timepoints (up to 168 hours) postdose; Part 2 (Period 2) Day 2 predose and multiple timepoints (up to 144 hours) postdose]
- Parts 1 and 2: AUClast: Area Under the Plasma Concentration-time Curve from Time 0 to the Time of the Last Quantifiable Concentration for Soticlestat [Parts 1, 2 (Period 1):Day 1 predose and multiple timepoints (up to 96 hours) postdose;Part 1 (Period 2) Day 5 predose and multiple timepoints (up to 168 hours) postdose; Part 2 (Period 2) Day 2 predose and multiple timepoints (up to 144 hours) postdose]
- Parts 1 and 2: Tmax: Time to Reach the Maximum Plasma Concentration (Cmax) for Soticlestat [Parts 1, 2 (Period 1):Day 1 predose and multiple timepoints (up to 96 hours) postdose;Part 1 (Period 2) Day 5 predose and multiple timepoints (up to 168 hours) postdose; Part 2 (Period 2) Day 2 predose and multiple timepoints (up to 144 hours) postdose]
Secondary Outcome Measures
- Number of Participants Who Experience at Least 1 Treatment-Emergent Adverse Event (TEAE) [Baseline up to Day 52]
- Number of Participants Who Experience Clinically Significant Abnormal Values for Laboratory Evaluations [Baseline up to Day 52]
- Number of Participants Who Experience Clinically Significant Abnormal Values for Vital Signs [Baseline up to Day 52]
- Number of Participants Who Experience Clinically Significant Abnormal Values for Electrocardiogram (ECG) [Baseline up to Day 52]
- Number of Participants With Suicidal Ideation or Suicidal Behavior as Measured Using Columbia-Suicide Severity Rating Scale (C-SSRS) [Baseline up to Day 52]
The C-SSRS is an interview-based rating scale to systematically assess any suicidality, suicidal behavior, or suicidal ideation. Any suicidality is emergence of any suicidal ideation or suicidal behavior. Any suicidal behavior is indicated when response is "yes" for any these questions- actual attempt to suicide, engaged in non-suicidal self-injurious behavior, interrupted attempt, aborted attempt, preparatory acts. Any suicidal ideation is indicated when response is "yes" for any of these questions- wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with methods without intent to act or some intent to act, without specific plan or with specific plan and intent to suicide.
