OSAKA, Japan -- June 19, 2014

Takeda Pharmaceutical Company Limited (TSE:4502) announced today that it has
voluntarily decided to end the development program for orteronel (TAK-700) for
prostate cancer. The decision follows the results of two Phase 3 clinical
trials in metastatic, castration resistant prostate cancer (mCRPC). The
studies found while orteronel plus prednisone could extend the time patients
lived before their cancer progressed, it did not extend overall survival in
these patients. After careful consideration of the data from these trials, the
company has determined that the drug has not demonstrated a clinical profile
sufficient to move forward in mCRPC, given the availability of other

On May 14, 2014, Takeda announced results from ELM-PC4, a pivotal,
international, double blind, randomized Phase 3 trial in men with mCRPC who
had not received chemotherapy, which showed that orteronel plus prednisone
improved radiographic progression free survival (rPFS) compared to prednisone
alone, one of the study’s two primary endpoints, but did not show a
statistically significant improvement in the study’s second primary endpoint
of overall survival (OS). A previously reported Phase 3 trial, ELM-PC5, in men
with mCRPC that had progressed during or following chemotherapy, was unblinded
in 2013 after a pre-specified interim analysis indicated that orteronel plus
prednisone would likely not meet the primary endpoint of improved overall
survival when compared to the control arm. The interim analysis did show an
advantage for orteronel plus prednisone for the secondary endpoint,
radiographic progression-free survival over the control arm. There were no
significant safety concerns in either study.

Takeda is in communication with trial investigators and the relevant
regulatory authorities, to provide them with updated and current information
in compliance with local regulations. Takeda is working with trial
investigators and local regulatory authorities to ensure that patients who
participated in the orteronel (TAK-700) trials are transitioned to appropriate
therapies so that trial participants receive appropriate care. Patients
enrolled in the orteronel (TAK-700) clinical trials are urged to consult their
study investigators to address any questions, and before making any changes to
their medication. For additional information, please visit www.takeda.com.

Takeda remains committed to oncology and to the treatment of prostate cancer.
