YM BioSciences Announces Result of Cytopia Limited Shareholder Vote

MISSISSAUGA, ON, Jan. 12 /PRNewswire-FirstCall/ - YM BioSciences Inc. today announced that YM BioSciences' previously announced proposal to acquire all the shares of Australian biopharmaceutical company, Cytopia Ltd., under a Scheme of Arrangement was subject to a positive vote of Cytopia shareholders both by number of shares and number of shareholders. At the Scheme Meeting held in Melbourne on January 12, 2010 99.67% of the shares voted by Cytopia shareholders were reported by Cytopia to have been voted in favour of the Scheme; 196 of the 213 shareholders voting at the meeting, representing 92.02% of all Cytopia shareholders represented, voted in support of the Scheme. Accordingly Cytopia shall now apply to the Court for orders approving the Scheme. The Court hearing is anticipated to occur on January 15, 2010 in Melbourne with the final court orders being lodged with the Australian Securities and Investments Commission, ("ASIC") on January 18, 2010.

Following lodgement of documentation with ASIC, the arrangement becomes irrevocable and trading in Cytopia shares on the Australian Stock Exchange will be suspended. The Implementation Date of the Scheme, giving effect to the merger, is anticipated to occur on January 28, 2010.

"We are delighted by the positive outcome of our proposal to merge Cytopia into YM, resulting in a broad drug development portfolio of considerable promise. The JAK provenance, coming as it does from Dr. Andrew Wilks, the discoverer of the Janus Kinase family, and from which Cytopia's vascular disrupting agent emerged, provides an exceptional pedigree," said David Allan, Chairman and CEO of YM BioSciences. "Both of Cytopia's drugs are in clinical development and both are in areas of considerable interest to the pharmaceutical industry worldwide."

"This opportunity to link our earlier stage products in development to YM's well-advanced development of nimotuzumab both directly and through its extensive network of international licensees offers our shareholders and our management both risk mitigation and a much enhanced prospect for success in this business of drug development," said Andrew Macdonald, CEO of Cytopia Ltd. "YM's positioning in North America, with its listing within the world's most important capital market for companies in this industry, adds a further dimension of advantage to our shareholders as we offer a further dimension to the YM's portfolio."

Under the Scheme of Arrangement YM BioSciences offered one common share of YM in exchange for each 11.74, common shares of Cytopia (0.0852 YM for each Cytopia common share) subject to adjustment should the volume-weighted-average price (VWAP) of YM shares for the 20 trading days ending January 15, 2010 fall outside of the range of C$1.29 and C$2.397. As at the close of business January 9, 2010 the VWAP for the prior 15 days has been calculated as C$1.551.

About YM BioSciences

YM BioSciences Inc. is a life sciences product development company that identifies and advances a portfolio of promising cancer-related products at various stages of development. The Company is currently developing two late-stage products: nimotuzumab, an EGFR-targeting Affinity-Optimized Antibody(TM), and AeroLEF(R), a proprietary, inhaled-delivery composition of free and liposome-encapsulated fentanyl. YM has proven regulatory and clinical trial expertise and a diversified business model designed to reduce risk while advancing clinical products toward international approval, marketing and commercialization.

Nimotuzumab is a humanized monoclonal antibody in development worldwide, targeting multiple tumor types primarily in combination with radiation and chemoradiation. It is significantly differentiated from all other currently marketed EGFR-targeting agents due to its remarkably benign side-effect profile. Nimotuzumab's anti-tumor activity has led to its approval for marketing in 23 countries. In more than 5,000 patients reported as having been treated with nimotuzumab worldwide to date, no Grade IV incidents of radiation dermatitis have been described, severe rash has not been observed and reports of the other severe side-effects that are typical of EGFR-targeting molecules have been rare. Nimotuzumab is licensed to YM's majority-owned subsidiary, CIMYM BioSciences Inc., by CIMAB S.A., and was developed at the Center of Molecular Immunology. YM is developing AeroLEF for the treatment of moderate to severe acute pain. The product is differentiated from other approaches using opioids because patients are able to individually control the analgesia required for their differing intensities of pain. AeroLEF met all endpoints in a randomized Phase II trial and is currently being prepared for late-stage development internationally.
