Population

48 male volunteers (6 cohorts of 8 subjects each)

Comparison

Active compound (single-ascending-dose) vs Placebo

Design

Other

Follow-up

up to day 2

Implication

Supports omitting dedicated TQT studies when FIM ECG meets regulatory QT thresholds; extends evidence for integrated early-phase QT assessment.

Detailed ECG monitoring during a first-in-man study can provide QT interval data of regulatory acceptable accuracy, potentially avoiding the need for a separate thorough QT study.
