In addition, in the
first-line STELLAR 3 and 4 trials in poor performance status (PS2) patients,
XYOTAX demonstrated a statistically significant increase in survival among
women (198 patients total), with a 60 percent increase in 1-year survival.

"The survival advantage seen in women in the STELLAR 3 and 4 studies is
worthy of note. The trials were stratified by gender and survival by gender is
pre-specified in the analysis plan," stated Scott C. Stromatt, M.D., Sr. Vice
President of Clinical Development and Regulatory Affairs at CTI. "We plan to
explore these results later this summer in our discussions with FDA regarding
the regulatory submission for XYOTAX."


If(!!!!) the effect is seen across all three Stellars (where is mention of Stellar 2 BTW) then they might have something. But Post Hoc analysis of two of the three trials is just not reliable. (And the mention of having it in the Analysis Plan is almost certainly meaningless - typically companies have 10's of things in there so the chance of finding 'positive' results on one is pretty good.)

Your friendly neighborhood statistical pain in the butt.
