                 ORAL CANCER DRUG REVLIMID(R) RECEIVES POSITIVE
                 OPINION FOR TREATMENT OF MULTIPLE MYELOMA FROM
                            EUROPEAN MEDICINES AGENCY

NEUCHATEL,  SWITZERLAND - (MARCH 23, 2007) - CELGENE INTERNATIONAL SARL (NASDAQ:
CELG)   announced   today  that  its   innovative   oral  cancer  drug  REVLIMID
(lenalidomide)  has  received a positive  opinion  from the  European  Medicines
Agency  (EMEA) for use in  combination  with  dexamethasone  as a treatment  for
patients with multiple myeloma who have received at least one prior therapy. The
EMEA's  Committee  for  Medicinal  Products for Human Use (CHMP),  which reviews
applications  for all 27 Member  States in the  European  Union  (EU) as well as
Norway and Iceland, has recommended  approval for REVLIMID.  The CHMP's positive
opinion will be forwarded to the European  Commission that generally follows the
recommendation  of the CHMP and issues final  marketing  approval  within two to
three months.

Multiple myeloma is the second most commonly  diagnosed blood cancer.  According
to the International  Myeloma Foundation,  there are an estimated 750,000 people
with MM worldwide. There are more than 85,000 men and women in Europe undergoing
treatment for multiple myeloma,  and 25,000 people are expected to die from this
blood cancer in 2007.

"The CHMP  recommendation is an especially  important and positive milestone for
Celgene.  We are  fully  committed  to  deliver  REVLIMID  to  patients  in need
throughout  the EU," said Aart  Brouwer,  President  of  Celgene  International.
"We're  optimistic  that  REVLIMID will have broad support based on its value to
patients and to the healthcare system. Upon approval we are prepared to initiate
next steps for pricing,  reimbursement and distribution  plans for all EU member
states."

The  positive  opinion  from the CHMP was based  upon the  safety  and  efficacy
results of two large,  randomized pivotal Phase III special protocol  assessment
trials,  North American Trial MM-009 and International Trial MM-010,  evaluating
REVLIMID plus  dexamethasone  in multiple myeloma patients that have received at
least one prior therapy.

"The  positive  opinion of REVLIMID  from the CHMP is an important  step forward
towards  providing a new oral  therapeutic  option for this particular  group of
patients  with  multiple  myeloma,"  said  Graham  Burton,   M.D.,  SVP,  Global
Regulatory  Affairs and  Pharmacovigilance  for  Celgene.  "We are  committed to
continue our work with the European authorities to bring REVLIMID to patients in
need as quickly as possible."




Upon the European  Commission's  approval  for  REVLIMID as an oral  combination
treatment with  dexamethasone for multiple myeloma patients who have received at
least one prior therapy,  Celgene Europe will initiate next steps for marketing,
distribution, pricing and reimbursement approvals for all EU member states.

myeloma  by the U.S.  Food  and  Drug  Administration  (FDA).  REVLIMID  is also
approved for treatment of patients with transfusion-dependent anemia due to low-
or  intermediate-1-risk   myelodysplastic  syndromes  (MDS)  associated  with  a
deletion  5q  cytogenetic  abnormality  with or without  additional  cytogenetic
abnormalities by the FDA.

ABOUT MULTIPLE MYELOMA

Multiple  myeloma  (also known as myeloma or plasma cell myeloma) is a cancer of
the blood in which malignant  plasma cells are  overproduced in the bone marrow.
Plasma  cells  are  white  blood  cells  that  help  produce  antibodies  called
immunoglobulins  that fight infection and disease.  However,  most patients with
multiple  myeloma  have  cells  that  produce  a form of  immunoglobulin  called
paraprotein  (or M protein)  that does not benefit the body.  In  addition,  the
malignant  plasma cells replace  normal plasma cells and other white blood cells
important to the immune system.  Multiple myeloma cells can also attach to other
tissues of the body, such as bone, and produce tumors.  The cause of the disease
remains unknown.
