Brief Summary:
This is a 3-part Phase 1 dose-ranging study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single (Part 1) and multiple (Part 2) ascending doses of BCX9930 in healthy subjects and in subjects with paroxysmal nocturnal hemoglobinuria (PNH; Part 3). Pharmacokinetics is an analysis of how the body handles the study drug BCX9930 and pharmacodynamics is an analysis of the activity that the study drug BCX9930 may have in the body.
Detailed Description:
Up to 6 sequential ascending dose cohorts are planned to be dosed in a sequential manner in Part 1 of the study. Eight subjects will be treated with a single dose of the study drug per dose cohort (6 subjects per cohort will receive BCX9930 and 2 subjects per cohort will receive matching placebo). Escalation to the next higher dose level will occur only after completion of a review of clinical safety and pharmacokinetics by the Sponsor and PI.
Up to 7 ascending, multiple dose cohorts will be enrolled in a sequential manner in Part 2 of the study. In Cohorts 1 through 3, twelve subjects will be treated with either a 7-day or 14-day course of study drug (10 subjects per cohort will receive BCX9930 and 2 subjects per cohort will receive matching placebo) administered orally. In Cohorts 4 through 7, twelve subjects will be treated with a 3-day course of study drug (10 subjects per cohort will receive BCX9930 and 2 subjects per cohort will receive matching placebo) administered orally. The daily dose may be split into 2 times daily (BID) or 3 times daily (TID) dosing for the multiple ascending dose part as needed. Escalation to the next higher dose level in Part 2 will occur only after completion of a review of clinical safety and pharmacokinetics by the Sponsor and PI.
Part 3 of the study consists of up to 2 sequential ascending multiple dose cohorts of up to 8 subjects; each cohort may enroll up to 4 subjects with PNH who are naïve to both eculizumab and ravulizumab and up to 4 subjects with PNH who are currently being treated with either eculizumab or ravulizumab. In each cohort, subjects will receive one daily dose of BCX9930 on Days 1 to 14 and a higher daily dose on Days 15 to 28. Cohort 2 will start after independent data monitoring committee (DMC) review of Cohort 1 data and communication of their evaluation to Part 3 investigators. In South Africa, subjects that have clinical benefit from BCX9930 will be allowed to continue dosing for up to 48 weeks.
Up to 7 ascending, multiple dose cohorts will be enrolled in a sequential manner in Part 2 of the study. In Cohorts 1 through 3, twelve subjects will be treated with either a 7-day or 14-day course of study drug (10 subjects per cohort will receive BCX9930 and 2 subjects per cohort will receive matching placebo) administered orally. In Cohorts 4 through 7, twelve subjects will be treated with a 3-day course of study drug (10 subjects per cohort will receive BCX9930 and 2 subjects per cohort will receive matching placebo) administered orally. The daily dose may be split into 2 times daily (BID) or 3 times daily (TID) dosing for the multiple ascending dose part as needed. Escalation to the next higher dose level in Part 2 will occur only after completion of a review of clinical safety and pharmacokinetics by the Sponsor and PI.
Part 3 of the study consists of up to 2 sequential ascending multiple dose cohorts of up to 8 subjects; each cohort may enroll up to 4 subjects with PNH who are naïve to both eculizumab and ravulizumab and up to 4 subjects with PNH who are currently being treated with either eculizumab or ravulizumab. In each cohort, subjects will receive one daily dose of BCX9930 on Days 1 to 14 and a higher daily dose on Days 15 to 28. Cohort 2 will start after independent data monitoring committee (DMC) review of Cohort 1 data and communication of their evaluation to Part 3 investigators. In South Africa, subjects that have clinical benefit from BCX9930 will be allowed to continue dosing for up to 48 weeks.
