          Neurocrine Biosciences Initiates Phase III Clinical Trial for
                    NBI-34060 In Chronic (Primary) Insomnia

San Diego,  CA, November 16,  2001-Neurocrine  Biosciences,  Inc.  (NASDAQ:NBIX)
today announced that it has initiated the first pivotal Phase III clinical trial
of NBI-34060 in approximately 500 patients with chronic (primary) insomnia.  The
Phase  III  clinical  trial  is  a  randomized,  double  blind,  parallel-group,
multi-center  study to evaluate the safety of two doses of  NBI-34060  Immediate
Release  (IR) for the  long-term  treatment  of chronic  (primary)  insomnia  in
adults.  The trial will be conducted in  approximately  40 medical  sites in the
United States and Europe.

"This trial is a major turning point for  Neurocrine as we begin our first Phase
III program in the history of the  Company,"  said Gary A. Lyons,  President and
CEO of Neurocrine Biosciences.

"Two  additional  pivotal  Phase III trials  with  NBI-34060-IR  are  planned to
initiate  shortly.   We  are  implementing  an  aggressive  Phase  III  clinical
evaluation of NBI-34060 to support  registration  of this new sedative  hypnotic
for short-term and long-term  treatment of insomnia," said Henry Pan, M.D. Ph.D,
Executive Vice President of Clinical  Development  and Chief Medical Officer for
Neurocrine Biosciences.

Background on NBI-34060 for Insomnia
- ------------------------------------
NBI-34060  is a  non-benzodiazepine  that acts on a specific  site of the GABA-A
receptor.  It  is  through  this  same  mechanism  that  the  non-benzodiazepine
therapeutics currently on the market produce their sleep-promoting effects.

Insomnia is a prevalent  neurological  disorder in the United States, with about
one-half of the adult  population  reporting  trouble  sleeping a few nights per
week or more,  according to the National Sleep Foundation  (NSF).  Approximately
29% of the adult population reports that they experience insomnia every night or
almost  every night.  Despite this  widespread  prevalence,  insomnia  remains a
disorder with high unmet medical needs,  including the ability to maintain sleep
throughout the night without next-day residual effects.
