Food Effect and Bioequivalence Study of Simufilam Tablets in Healthy Volunteers
Study Details
Study Description
Brief Summary
This is a single-center, randomized, four-treatment, four-sequence crossover study in healthy volunteers to estimate the effect of food on the PK of simufilam following oral 100 mg doses and to estimate its relative bioavailability compared to the earlier Phase 2 simufilam tablet in the fasted state. A total of twenty four (24) healthy volunteers (12 male and 12 female) will be enrolled into this study. Subjects will be randomly assigned to one of four treatment sequences (6 subjects/sequence).
Condition or Disease | Intervention/Treatment | Phase |

Phase 1 |
Detailed Description
This study will compare the PK of the Phase 3 simufilam 100 mg oral tablet when taken fasted versus following a high-fat or low-fat meal. Additionally, the Phase 3 oral tablet will be compared to the Phase 2 oral tablet for bioequivalence under fasted conditions.

Outcome Measures
Primary Outcome Measures
- Cmax [24 hours]
The maximum concentration determined directly from individual concentration-time data
- Tmax [24 hours]
Time to reach maximum concentration
- AUClast [24 hours]
Area under the curve to the time of the last quantifiable concentration, calculated using the linear trapezoidal method
- AUCinf [24 hours extrapolated to infinity]
Area under the curve extrapolated to infinity; calculated as: AUCinf = AUClast + Clast/λz
- Clast [24 hours]
The last quantifiable concentration determined directly from individual concentration-time data
- Tlast [24 hours]
Time of the last quantifiable concentration
- λz [24 hours]
The observed elimination rate constant; estimated by linear regression through at least three data points in the terminal phase of the log concentration-time profile
- T1/2 [24 hours]
The observed terminal elimination half-life calculated as: T1/2 = ln(2)/λz
