FOR  IMMEDIATE  RELEASE

  SERONO ANNOUNCES RESULTS OF FDA ADVISORY COMMITTEE ON SEROSTIM(R) FOR USE IN
                       PATIENTS WITH SHORT BOWEL SYNDROME

ROCKLAND,  MA,  JUNE 25, 2003 - Serono, Inc. announced that the Gastrointestinal
Drugs  Advisory Committee for the U.S Food and Drug Administration (FDA) did not
recommend  approval  at  this  time of Serostim(R) [somatropin (rDNA origin) for
injection]  for  use  in the treatment of short bowel syndrome (SBS) in patients
receiving  specialized  nutritional  support.

The  committee's view was based, in part, on the fact that the majority of study
patients were treated in a single specialty treatment center.

"Serono is disappointed with the recommendation of the Advisory Committee," said
Dr.  Joseph Gertner, Vice President and Head of Metabolic Endocrinology Clinical
Development, Serono, Inc.  "There is a substantial clinical need to provide more
effective  treatments  to  patients  with  short  bowel  syndrome, a rare orphan
condition.  We  will  evaluate  our next steps and will continue to work closely
with  the  FDA  to  fully  understand  and  address  the  outstanding  issues."

The  Advisory  Committee  recommendation  is considered by the FDA in making its
decision.  This  committee  recommendation  does  not  impact the current use of
Serostim(R) in  the  approved  indication  of  AIDS  wasting.

SBS  is  a rare, serious and potentially life-threatening condition that follows
extensive  surgical  removal  of the small intestine as a treatment for acute or
chronic  disorders  of  the  intestine.  Removal of a large portion of the bowel
results  in  impaired absorption of nutrients.  Currently the standard treatment
for  SBS  involves careful management of dietary intake, or where appropriate, a
process referred to as parenteral nutrition in which patients are fed through an
intravenous  tube.  Surgical  transplant  of the intestine may also be performed
for  this condition. There are an estimated 10,000-20,000 patients in the United
States  who  are  receiving  long-term intravenous parenteral nutrition for SBS.

At the committee meeting, Serono presented data from a pivotal study to evaluate
the change in total parenteral nutrition requirements in adult patients with SBS
who  are  dependent  on  parenteral  nutrition. In the double-blind, controlled,
parallel  group  Phase  III  study,  41  patients  were  randomly  assigned  to



one  of  three  study  arms: a specialized diet supplemented with oral glutamine
alone;  Serostim(R)  with  a  specialized  diet  alone;  or  Serostim(R)  with a
specialized  diet  with  glutamine.

The  results  of the study were positive with total parenteral nutrition volume,
total  parenteral  nutrition  calories,  and  frequency  of  infusion decreasing
significantly more in the Serostim(R) plus specialized diet group as compared to
the  glutamine  supplemented  specialized diet group (p values 0.043, 0.005, and
0.025  respectively).  The  corresponding  reductions  in  the  Serostim(R) plus
glutamine  supplemented  diet  group  as  compared to the glutamine supplemented
specialized  diet  group  were  larger and all were highly significant (p values
less  than  0.001).

Serostim(R)  was  granted  an  orphan  drug  designation  for  use  alone  or in
combination  with  glutamine  in  the  treatment  of  patients  with short bowel
syndrome  by  the  FDA  Office  of  Orphan  Products  Development.

Serostim(R)  is  currently approved by the FDA for the treatment of AIDS wasting
or  cachexia.

ABOUT  SEROSTIM(R)
Serostim(R)  [somatropin  (rDNAorigin) for injection] is the only growth hormone
approved  by  the  US  Food  and  Drug  Administration for the treatment of AIDS
wasting or cachexia. Serostim(R) received FDA accelerated approval in 1996 based
upon  the  analysis  of  changes  in body weight and lean body mass in surrogate
endpoints  in clinical studies up to 12 weeks in duration. Serostim(R) is now on
the  market  in  12  countries.

Serostim(R),  when  taken as currently prescribed in 6mg doses over 12 weeks, is
generally  well  tolerated. The most common adverse reactions to Serostim(R) are
increased  tissue  turgor  (generally  swelling  of  hands  and  feet)  and
musculoskeletal  discomfort  (pain,  swelling  or  stiffness). Generally mild to
moderate  in  severity,  these  symptoms  usually  resolve  spontaneously  with
continued  treatment  or are effectively managed with analgesic therapy or after
reducing  the  weekly  dose.  Elevations  in  mean blood glucose levels can also
occur.  Patients  with  other  risk  factors  for  glucose intolerance should be
monitored  closely.  When used in patients with HIV disease, Serostim(R) must be
used  in  conjunction  with antiretroviral therapy. Full prescribing information
for Serostim(R) is available at www.aidswasting.com.
