FOR  IMMEDIATE  RELEASE

    SERONO'S SEROSTIM(R) RECEIVES FULL APPROVAL FROM FDA FOR TREATMENT OF AIDS
                                     WASTING

SEROSTIM(R) GRANTED ACCELERATED APPROVAL IN 1996 AS TREATMENT FOR AIDS PATIENTS
        WITH WASTING OR CACHEXIA, A SERIOUS AND LIFE THREATENING DISEASE

    CONFIRMATORY MULTI-CENTER, PLACEBO-CONTROLLED STUDY SUBSTANTIATES PREVIOUS
   FINDINGS OF INCREASED LEAN BODY MASS AND IMPROVEMENT IN PHYSICAL ENDURANCE


ROCKLAND,  MA,  AUGUST  29, 2003 - Serono, Inc. announced today that the US Food
and  Drug  Administration  (FDA)  has  granted  full  approval  for  Serostim(R)
[somatropin (rDNA origin) for injection] which is indicated for the treatment of
HIV  patients  with  wasting  or  cachexia  to  increase lean body mass and body
weight,  and  improve  physical  endurance.(1)

Serostim(R)  received  accelerated approval in 1996, a special regulatory status
granted  by  the  FDA for approval of a drug that is used to treat patients with
serious  or  life-threatening  illnesses,  and  provides  meaningful therapeutic
benefit  over  any  existing  treatments.  Under  the  terms  of the accelerated
approval, Serono conducted a multi-center, confirmatory placebo-controlled study
with  Serostim(R).  Data from this trial substantiate previous study findings of
increased lean body mass and improvement in physical endurance with Serostim(R).
In  addition,  patients  in this study perceived an improvement in their wasting
symptoms  with  Serostim(R)  treatment.

"We  are  very  pleased that the FDA has granted full approval for Serostim(R),"
said  James  Sapirstein,  Executive  Vice  President,  Metabolic  Endocrinology,
Serono,  Inc.  "Wasting continues to be a major concern in the management of HIV
and  AIDS  treatment,  even  with  the  benefits of highly active antiretroviral
therapy.  Serostim(R) makes an important and positive difference in the physical
endurance  of  people  experiencing  HIV  wasting."

HIV-associated  wasting  is  a  chronically  debilitating  and  potentially
life-threatening  condition.  It is a metabolic disorder that causes the body to
use  vital  muscle  and organ tissue, which is critical for survival, for energy
instead  of  primarily  using  the

body's  stored  fat.  Loss  of  lean body mass, which consists of muscle tissue,
important  body  organ  tissue  and  blood  cells, can lead to increased risk of
opportunistic  infections,  illness,  and  extreme  fatigue  and  can profoundly
diminish  a  person's  quality  of  life.  Serostim(R)  was  granted orphan drug
designation  by  the  FDA  in  1991  for  this  condition.

CLINICAL STUDY OF SEROSTIM IN AIDS WASTING

The  full  approval  of  Serostim(R)  is  based upon a randomized, double-blind,
dose-ranging  study  that  confirmed the clinical efficacy of Serostim(R) in the
treatment  of  HIV  wasting.  The study treated 757 patients with HIV-associated
wasting  at US, European and other international trial sites.  Participants were
treated  with  placebo, Serostim(R) on alternate days (0.1 mg/kg) or Serostim(R)
on  a  daily  basis  (0.1mg/kg).

The  result  on  the  study's  primary  endpoint  of  cycle  work  output  was
statistically  significant  for  the Serostim(R) daily dose group as compared to
the  placebo group (p<0.0001). Positive results were also seen for the secondary
endpoint  of  change  in  lean body mass for the Serostim(R) daily dose group as
compared to the Serostim(R) alternate day group (p=0.017) and as compared to the
placebo  group  (p<0.0001).  In  addition,  patient  perception of the impact of
treatment on their wasting symptoms was positive with both doses of Serostim(R).

All  study  participants  completing the 12-week placebo-controlled phase of the
trial (n=646) continued treatment into an extension phase; 548 of these patients
completed  an  additional  12  weeks  of  active  treatment.  In these patients,
positive results in cycle work output and lean body mass either improved further
or  were  maintained  with  continued  treatment  with  Serostim(R).


ADDITIONAL  PRODUCT  INFORMATION

Serostim(R) [somatropin (rDNAorigin) for  injection]  is the only growth hormone
approved by the US Food and Drug Administration for the treatment of HIV wasting
or  cachexia.  The  recommended dose is 0.1 mg/kg daily (6 mg/day for patients >
55  kg).  Serostim(R)  0.1  mg/kg  every  other  day  should  be considered as a
starting  dose  in  patients  thought  to be at risk of certain adverse effects,
i.e.,  glucose  intolerance.

Serostim(R)  is  generally  well  tolerated.  The  most  common  adverse  events
associated  with  Serostim(R) therapy are mild to moderate muscle and joint pain
and  swelling/edema, which occur in a dose-related manner and often subside with
continued  treatment  or  dose  reduction.  Cases  of new onset impaired glucose
intolerance,  new onset type 2 diabetes mellitus and exacerbation of preexisting
diabetes  mellitus  have  been  reported in patients receiving Serostim(R). Some
patients  develop  diabetic  ketacidosis  and  diabetic  coma. In some patients,
therapy  with Serostim(R) necessitated initiation or adjustment of anti-diabetic



treatment.  Patients  with  a history of hyperglycemia or other risk factors for
glucose  intolerance  should  be  monitored  closely  during  treatment  with
Serostim(R).  Transient increases in glucose levels occur early in treatment and
should  be  monitored.

Use  of  growth hormone is contraindicated in treatment of patients in intensive
care  units  due  to  complications  following  open-heart  surgery or abdominal
surgery,  multiple accidental trauma or acute respiratory failure; patients with
active  neoplasia;  and  patients with known hypersensitivity to growth hormone.
Serostim(R) must  be  used  in  conjunction  with  antiretroviral  therapy.

Full  prescribing  information  for  Serostim(R),  including  important  safety
information,  is  available  at  www.serostim.com.
