Time frame
Blood serum samples taken pre-dose at Cycle 1 Day 1 (C1, D1), C1 D8, C1 D15, C2 D1, C4 D1, C5 D8, C6 D1 and Week 25 visit, extension phase C4 D1 and Day 1 of every fourth treatment cycle thereafter.

What was measured

Terminal phase half-life was calculated according to the following equation: t1/2 = 0.693/λz.

Analysis population: Pharmacokinetic population Included all participants who received at least 1 dose of luspatercept and had measurable luspatercept serum concentrations.

Groups in this outcome

Luspatercept

Luspatercept 1.0 mg/Kg SC on Day 1 of each 21-day treatment cycle

Placebo

Placebo (Volume equivalent to experimental arm) SC on Day 1 of each 21-day treatment cycle
