Study to Assess Amphotericin B Cystetic for Inhalation (ABCI) Doses in Healthy Volunteers & People With Cystic Fibrosis
|
A 3-part Study of ABCI: A Randomized, Double-blind, Placebo-controlled, Single-ascending Dose Phase 1a Study in Healthy Volunteers (Part A), a Randomized, Double-blind, Placebo-controlled, 14- and 28-day Multiple-ascending Dose Phase 1a Study in Healthy Volunteers (Part B), and a 28-day Open-Label Phase 1b Study in Subjects With Cystic Fibrosis (Part C)
|
This is a 3-part, single-ascending dose Phase 1a randomized, double-blind, placebo-controlled study in healthy volunteers (Part A) and multiple-ascending dose Phase 1a randomized, double-blind, placebo-controlled study in healthy volunteers (Part B), and a Phase 1b open-label study in subjects with CF (Part C) to assess the safety, tolerability, PK, and preliminary efficacy of ABCI. Subjects will be evaluated for eligibility during Screening within 30 days prior to Day 1 (Randomization; Visit 3). In Parts A and B, eligible healthy volunteers may be enrolled in the study and randomly allocated to treatment with ABCI or placebo as described below. In Part C, eligible subjects with CF may be enrolled in the study and receive treatment with ABCI as described below. Approximately 72 healthy subjects total will be randomized to 9 cohorts (48 subjects in 6 cohorts in Part A, 24 subjects in 3 cohorts in Part B) and approximately 20 subjects with CF will receive the medium dose (2 sentinel subjects) or high dose (up to 18 subjects) of ABCI in Part C.

- Experimental: Part A Healthy Volunteer
Subjects will be assigned to one of six planned dose cohorts and receive single doses of ABCI (0.5mg, 1.0mg, 2.0mg, 4.0mg, 6.0mg, 10.0mg). In each cohort, six subjects will receive ABCI and 2 will receive placebo
Interventions:
- Combination Product: ABCI
- Combination Product: Placebo
- Experimental: Part B Healthy Volunteer
Subjects will be assigned to one of three planned dose cohorts and receive a loading dose and multiple ascending doses of ABCI (loading dose 1.5mg/0.5mg daily, loading dose 6.0mg/2.0 daily, loading dose 10.0mg/4.0mg daily). In each cohort, six subjects will receive ABCI and 2 will receive placebo.
Interventions:
- Combination Product: ABCI
- Combination Product: Placebo
- Experimental: Part C People with Cystic Fibrosis
Subjects will be assigned to one of two planned dose cohorts of ABCI (loading dose 6.0mg/2.0mg daily, loading dose 10.0mg/4.0mg daily) for a total of 28 days of open-label study drug administration. Up to 20 subjects with CF, including 2 sentinels subjects not on cystic fibrosis transmembrane conductance regulator (CFTR) modulators will be enrolled. The 2 sentinel subjects will receive the medium dose/regimen. If the medium dose/regimen is tolerated, the remaining subjects with CF will receive the high dose/regimen of ABCI and may be either on CFTR modulators or not on CFTR modulators.
Intervention: Combination Product: ABCI
