Adaptive designs learn from accumulating trial data in real time and apply this knowledge to optimize subsequent study execution.
Interim analysis of accumulating trial data is important to protect participant safety during randomized controlled trials (RCTs).
We also suggest an approach to assessing maturity (readiness for analysis) of accumulating trial data according to the RMST method.

(8) and calculate the power, ωcurr, for the current data under the design assumptions as (10) ω curr = Φ Δ 2 var Δ ^ - z 1 - α / 2 Sometimes, for reasons of confidentiality of the accumulating trial data, it is desirable to estimate data maturity or power ignoring information on possible treatment effects.
