** Shares of Agios Pharmaceuticals AGIO.O rise ~3% to
$50.29; Fulcrum Therapeutics FULC.O up ~20% at $4.15
** Larger rival Pfizer PFE.N withdraws its sickle cell
disease drug, Oxbryta, from all approved markets, citing risks
of a painful complication and death
** Sickle cell disease is an inherited blood disorder that
affects the hemoglobin in red blood cells
** Analysts expect the withdrawal to help foster enrollment
for trials of rival sickle cell drugs, such as Agios' mitapivat
and Fulcrum's pociredir
** "We expect this will increase attention and urgency for
the clinical development of mitapivat," according to Piper
Sandler analysts
** Leerink Partners analysts say Oxbryta's withdrawal could
have a positive influence on the enrollment of FULC's
early-stage study, especially among patients who are on or have
been on Oxbryta alone
** Including session's gains, AGIO shares more than doubled
and FULC stock is down YTD
