简要总结

This is a phase 1, single-center, randomized, placebo-controlled, double-blind, multiple ascending-dose study to assess the safety, tolerability, and PK of oral TP-271 in healthy adult subjects. Male or female subjects aged 18 to 50 years who fulfill the inclusion/exclusion criteria will be enrolled in this study.

详细描述

This is a phase 1, single-center, randomized, placebo-controlled, double-blind, multiple ascending-dose study to assess the safety, tolerability, and PK of oral TP-271 in healthy adult subjects. Male or female subjects aged 18 to 50 years who fulfill the inclusion/exclusion criteria will be enrolled in this study.

Up to 5 cohorts of 8 subjects each (up to a total of 40 subjects) will be enrolled. Subjects in each cohort will be randomized 6:2 to receive multiple oral doses of TP 271 or placebo. Every effort will be made to dose all subjects in a cohort on the same day.

Doses of study drug will be administered orally either once daily in the morning or twice daily in the morning and evening from Days 1 to 7. In all subjects, the morning dose will be administered following an overnight fast (minimum 8 hours) of food and all beverages, except for water. For subjects in Cohorts D and E only, the evening dose will be administered following a minimum 3-hour fast of food and all beverages, except for water. Fasting in all cohorts will continue for at least 2 hours following each study drug administration.

During the Screening Period (within 28 days prior to the subject receiving study drug), each subject will be assessed for eligibility. Each subject must sign and date an ICF prior to undergoing any study-related procedures.

排除标准

  • History and/or presence of any clinically significant disease or disorder, such as cardiovascular, pulmonary, renal, hepatic, neurological, gastrointestinal, endocrine, psychiatric or mental disease or disorder, or mental or legal incapacitation, which, in the opinion of the PI, may either put the subject at risk due to participation in the study, influence the results of the study, or influence the subject's ability to participate in the study
  • Clinical laboratory values that fall outside of the eligibility range specified in Appendix D are exclusionary; for clinical laboratory values that are not included in Appendix D, values outside of the reference range are exclusionary, except for those parameters listed in Table 4).
