研究概览
简要总结
The study will assess the corrected QT (QTc) effects (electrocardiogram [ECG]) of motixafortide (BL-8040) 1.25 mg/kg (therapeutic dose) and 2 mg/kg (supratherapeutic dose) following a single subcutaneous (SC) injection relative to placebo in approximately 40 healthy subjects.
详细描述
This is a randomized, double-blind (in respect to BL-8040 and BL-8040-matching placebo dosing), placebo- and positive-controlled, 4-period, 4-way crossover study in healthy subjects.
A continuous 12-lead cardiodynamic ECG recording will be collected for approximately 24 hours on Day -1 of Period 1 for use in the optimized individual corrected QTc (QTcI) baseline calculations.
On Day 1 of Period 1, subjects will be randomized to 1 of 12 treatment sequences. Each treatment sequence comprises 4 treatment periods.
On Day 1 of each period, subjects will receive single-dose SC injection of BL-8040 (therapeutic or supratherapeutic dose), single-dose SC injection of BL-8040-matching placebo, or a single oral dose of moxifloxacin. Cardiodynamic readings, plasma pharmacokinetic (PK) samples, and blood pharmacodynamic (PD) samples will be collected at different time points prior to dosing and up to 24 hours postdose in each period, as appropriate.
There will be a washout period of 5-7 days between dosing in each period.
