Cytochroma Regains Rights to Lunacalcipol

June 1, 2012

MARKHAM, ON, June 1, 2012 /PRNewswire/ – Cytochroma today announced that it has
regained the rights to all indications in the United States (US) and in
Asian territories to lunacalcipol (previously known as CTA018) through
the termination of a license agreement between Cytochroma and
Mitsubishi Tanabe Pharma Corporation (“MTPC”).  MTPC and Cytochroma
mutually decided to suspend further development of lunacalcipol
injection based on changing US market dynamics.

“We are disappointed at the ending of our lunacalcipol collaboration
with Mitsubishi Tanabe, and are grateful for their strong support and
partnership over the last few years,” stated Dr. Charles W. Bishop,
President and CEO of Cytochroma.  “Lunacalcipol has shown great promise
as a new treatment for secondary hyperparathyroidism without the
calcemic side effects seen with existing vitamin D hormone therapies.
But, unfortunately, recent restrictions in government reimbursement for
drugs used in US dialysis patients make the continued development of
lunacalcipol injection for that patient population financially
unsustainable.  Our primary focus continues to be moving forward with
Phase 3 trials of our lead product, CTAP101 Capsules, which is under
development for secondary hyperparathyroidism in patients with vitamin
D insufficiency and stage 3 or 4 chronic kidney disease, a patient
population wherein drug reimbursement dynamics are much more

In July 2008, Cytochroma and MTPC signed a license agreement under which
Cytochroma granted MTPC an exclusive license in the US and Asia,
including Japan, to develop and commercialize lunacalcipol.
