** Medical aesthetics co's shares SIEN.O up 3.7% at $5.41
** A worldwide recall of breast implants from rival Allergan
Plc AGN.N opens up a ~$35 mln void in the U.S. market for SIEN
and Johnson & Johnson's JNJ.N Mentor breast implants to fill,
Craig-Hallum analyst Alexander Novak says
** FDA on Wed said it asked AGN to recall its Biocell
textured breast implants and tissue expanders across markets,
citing concerns over a rare form of cancer urn:newsml:reuters.com:*:nL4N24P38S
** FDA says the risk of the cancer with AGN's Biocell
textured implants is about six times compared with textured
implants from other manufacturers marketing in the United States
** "The Biocell recall should help continue, if not
accelerate, U.S. share gains (for Sientra)," Novak says, adding
that when SIEN launches outside the country, the AGN recall will
create a market "ripe for new entrants"
** SIEN intends to launch outside the United States in early
2020
** AGN has already stopped selling Biocell textured implants
in Europe and Canada and Novak says the opportunity outside the
U.S. sans Biocell is ~120 mln
** In March, FDA issued warning letters to SIEN and JNJ for
failing to comply with post-approval study requirements for
breast implants urn:newsml:reuters.com:*:nL3N2163TQ
** Up to Tuesday's close, SIEN stock had fallen ~59% YTD
