Details and patient eligibility

About

The study will consist of 2 parts, i.e. a single ascending dose part with integrated food effect assessment and assessment of relative bioavailability (Part A), and a multiple ascending dose part (Part B).

Part A will have a randomized, double-blind, placebo-controlled design. Subjects will receive single ascending doses of CFTX-1554 or placebo (as liquid formulation under fasted condition) in 7 subsequent cohorts. Drug intake under fed conditions, and as capsule under fasted conditions and under fed conditions (Periods 2 to 4), compared to liquid formulation under fasted conditions (Period 1) (1 single dose level only) will be assessed.

Part B will have a randomized, double-blind, placebo-controlled design, assessing multiple ascending oral doses of CFTX-1554 or placebo in 4 subsequent cohorts.
