Thanks to Kit Baum I have posted the following package on SSC:

TITLE
      'SSI': module to estimate sample size/power for randomized controlled trials

DESCRIPTION/AUTHOR(S)
      
      ssi  is meant to be used by investigators needing sample size/power
      estimation for prospective randomized controlled trials (RCTs).
      Although Stata ships with a sample size estimation command,
      sampsi, it is not designed to estimate trial sizes for
      non-inferiority or equivalence trials.
