Cytochroma Inc. Announces Completion of CDN$21 Million

Financing Round

Markham, ON – January 17, 2007 – Cytochroma announced today that it has

secured CDN$21 million in new funding for the advancement of product

development programs targeting vitamin D deficiency and related diseases in

chronic kidney disease (CKD). The new funding will support clinical trials with

three investigational new drug products which are scheduled to begin in 2007.

The financing round was led by The VenGrowth Advanced Life Sciences Fund,

Novo A/S, and GeneChem Technologies Venture Fund.

Cytochroma’s lead products include new treatments for secondary

hyperparathyroidism and vitamin D deficiency in patients with CKD. CTAP201 is

a new treatment for secondary hyperparathyroidism in patients with CKD. A

follow-on compound, CTA018, utilizes a novel, dual mechanism of action to both

activate the vitamin D hormone receptor and prevent vitamin D hormone

catabolism, which improves efficacy. CTAP101 will treat vitamin D deficiency,

which is now recognized as a common untreated disorder in the CKD patient

population. According to published literature, there are approximately 6.5 million

CKD stage 3-5 patients in North America with low levels of 25(OH)D, an

accepted measure of vitamin D status. This number is expected to grow to over

9 million patients by 2010. New therapies are needed to address this unmet

medical need.

“We believe that Cytochroma is uniquely positioned to drive investor returns with

high value pharmaceutical products, and the Company has demonstrated its

ability to execute clinical development programs,” stated Luc Marengère, Ph.D.,

Managing General Partner at VenGrowth.

“This new financing will allow Cytochroma to achieve key milestones in the

advancement of our product portfolio into the clinic,” stated Charles Bishop,

Ph.D., President and CEO of Cytochroma. “We are excited about our new

vitamin D products, and are aggressively moving our clinical plan forward in

2007.”
