Description of intervention(s) / exposure
Other interventions - ABCI
Other interventions - Placebo

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

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.

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.
