  Approval in the European Union

CAMBRIDGE, Mass. & LAUSANNE, Switzerland -- March 22, 2013

ARIAD Pharmaceuticals, Inc. (NASDAQ: ARIA) today announced that the Committee
for Human Medicinal Products (CHMP) of the European Medicines Agency (EMA) has
adopted a positive opinion on the marketing authorization application for
Iclusig™ (ponatinib) for two indications:

  *The treatment of adult patients with chronic phase, accelerated phase or
    blast phase chronic myeloid leukaemia (CML) who are resistant to dasatinib
    or nilotinib; who are intolerant to dasatinib or nilotinib and for whom
    subsequent treatment with imatinib is not clinically appropriate; or who
    have the T315I mutation, or
  *The treatment of adult patients with Philadelphia-chromosome positive
    acute lymphoblastic leukaemia (Ph+ ALL) who are resistant to dasatinib;
    who are intolerant to dasatinib and for whom subsequent treatment with
    imatinib is not clinically appropriate; or who have the T315I mutation.

“The positive recommendation by the CHMP of Iclusig for use in CML and Ph+ALL
provides a broad indication statement for Iclusig in resistant and intolerant
patients with Philadelphia positive leukaemias, including many patients who
have failed only one prior tyrosine kinase inhibitor,” stated Harvey J.
Berger, M.D., chairman and chief executive officer of ARIAD. “We appreciate
the substantial efforts of the CHMP in reaching this positive opinion so
rapidly as a consequence of Iclusig’s accelerated assessment designation, and
we look forward to the anticipated marketing authorization by the European
Commission around mid-2013.”

Although Iclusig was studied in Ph+ ALL patients who were resistant or
intolerant to dasatinib or nilotinib, nilotinib is not approved for the
treatment of Ph+ ALL.

The CHMP granted ARIAD accelerated assessment for its review of the Iclusig
marketing authorization application last summer. Accelerated assessment was
introduced by the European Union in 2005. Its aim is to help speed access for
patients to new medicines of major public-health interest. Companies can
request accelerated assessment provided they are able to demonstrate that
their product responds to an unmet medical need and is expected to have a
major impact on medical practice.

The CHMP is a scientific committee composed of representatives from the
27-member states of the European Union (EU), and Iceland and Norway. The CHMP
reviews medical product applications on their scientific and clinical merit
and provides advice to the European Commission, which has the authority to
approve medicines for the European Union.

CML is a cancer of the white blood cells that is diagnosed in approximately
7,000 patients each year in Europe^[1]. CML and Ph+ ALL patients treated with
tyrosine kinase inhibitors (TKIs) can develop resistance or intolerance over
time to these therapies. Iclusig is a targeted cancer medicine discovered and
developed at ARIAD. It was designed by ARIAD scientists using ARIAD’s platform
of computational chemistry and structure-based drug design to inhibit BCR-ABL,
including drug-resistant mutants that arise during treatment. Iclusig is the
only TKI that has received a positive opinion from the CHMP for an indication
that includes CML and Ph+ ALL patients with the T315Imutation.

About CML and Ph+ ALL

CML is characterized by an excessive and unregulated production of white blood
cells by the bone marrow due to a genetic abnormality that produces the
BCR-ABL protein. After a chronic phase of production of too many white blood
cells, CML typically evolves to the more aggressive phases referred to as
accelerated phase and blast crisis. Ph+ ALL is a subtype of acute
lymphoblastic leukaemia that carries the Ph+ chromosome that produces BCR-ABL.
It has a more aggressive course than CML and is often treated with a
combination of chemotherapy and tyrosine kinase inhibitors. The BCR-ABL
protein is expressed in both of these diseases.
