研究概览
简要总结
The primary objective of the study is to evaluate the safety and tolerability of single and multiple doses of TBA-7371 in healthy subjects
详细描述
Three - part, partially-blinded, placebo controlled, combined single ascending dose with a food effect cohort and multiple ascending dose and a drug-drug interaction study to be conducted in one study center in the United States.
Part 1 has a single ascending dose (SAD) design with up to 5 planned dose levels. Based on the interim PK for the dose escalation decisions, a dose cohort will be selected to return for an additional dose after a high calorie, high fat meal.
Safety will be assessed throughout the study; serial ECGs and serial blood samples will be collected for the safety and PK assessment of TBA-7371. Dose escalation to the next cohort (i.e., dose level) will not take place until the Sponsor, in conjunction with the Principal Investigator, has determined that adequate safety, tolerability and PK from the previous cohort has been demonstrated to permit proceeding to the next cohort.
Interim PK analyses will be performed for the dose escalation decisions, to select the intermediate dose for the food effect cohort, and to reconsider the sampling time points as the study progresses. All samples will be sent for analysis and the bioanalytical lab will be unblinded and only run the analysis on active treatment subjects. Data from the analysis used for the escalation meetings will only include active treatment subjects, and will be blinded by subject.
Subjects will be housed in the WCT clinic from at least 24 hours prior (from Day -2), until 48 hours after dosing. Subjects will return for subsequent follow up safety and PK assessments on Day 4 and will be contacted via a phone call for follow-up questioning about adverse events 7 days later (Study Day 11). One cohort will return after a washout of at least 7 days or five half-lives (whichever is longer) of their fasting dose to receive the same intermediate dose (TBD mg) under fed conditions.
