Chinese Joint Venture Completed

Jun 29 2011

SAN DIEGO, California -– MediciNova Inc, a biopharmaceutical company publicly traded on the Nasdaq Global Market (Nasdaq: MNOV) and the Jasdaq Market of the Osaka Securities Exchange (4875) and Zhejiang Medicine Co., Ltd. (ZMC) traded on the Shanghai Stock Exchange (600216) today announced the execution of a Joint Venture agreement for the formation of a Joint Venture Company to develop and commercialize MediciNova’s MN-221 in China. The completion of the agreement between MNOV and ZMC allows the JV to complete the final approval process with the Ministry of Commerce of the People’s Republic of China.

“We are pleased with the completion of this important step and look forward to the JV advancing toward the development of MN-221 in China” said Yuichi Iwaki M.D., Ph.D., chief executive officer of MediciNova, Inc. Chunbo Li, chairman of Zhejiang Medicine Company commented, “We plan for the JV to file an IND by year end to commence clinical development for MN-221 in China. We are eager to work closely with the Chinese FDA to advance the development of MN-221 to address the growing need for new emergency asthma therapies in China.”

In China, increasing urbanization and adoption of Western lifestyles are predicted to produce a sharp increase in the prevalence of asthma during the next decade. Due to China’s large population, a 2% increase in the prevalence of asthma would result in an additional 20 million people with the disease. The prevalence of asthma symptoms is higher in urban areas than rural areas of China. Asthma prevalence and emergency room visits are expected to grow substantially in the future due to increased diagnosis of asthma from continued migration of people from rural areas to cities with better access to medical care. High air pollution, a known contributor to acute exacerbations of asthma, is
expected to increase as the growing middle class in China buys more automobiles. The growing middle class in China is demanding better health care and access to better pharmaceutical products. The percentage of the Chinese population that can afford to pay for premium-priced pharmaceutical products out of pocket is expected to increase as the middle class continues to grow. All of these factors bode well for a very attractive market opportunity for MN-221 in China.

According to the Global Burden of Asthma report (M. Masoli, D. Fabian, S. Holt, R. Beasley), there were 27.8 million people with asthma in the China/Taiwan/Mongolia region. More than one third of people with asthma in this region require urgent medical care, emergency room visits, or hospitalization for asthma attacks. Mortality data also reflect the burden of severe asthma in the region with China having one of the highest asthma case fatality rates in the world.

About MN-221

MN-221 is a novel, highly selective, beta(2)-adrenergic receptor agonist in development as an intravenous treatment for acute exacerbations of asthma and chronic obstructive pulmonary disease (COPD) exacerbations. Preclinical testing in vitro and in vivo shows MN-221 to be more selective for the beta(2)-adrenergic receptor than other beta(2)-adrenergic receptor agonists commonly used for acute exacerbations of asthma. This improved selectivity, coupled with its partial agonist activity at beta(1)-adrenergic receptors, may yield bronchodilation without harmful cardiovascular side effects that are commonly observed with other agents. MediciNova has completed several Phase I and 2a trials, and is currently conducting a Phase 2b study in patients with acute exacerbations of asthma. MN-221 demonstrated significant improvements in FEV1 in all asthma trials as well as a 45% decrease in the hospitalization rate when added to current standard of care in a Phase 2a study of acute asthma patients in the emergency room. MediciNova also completed a Phase 1b clinical study of MN-221 in patients with stable, moderate to severe COPD in which MN-221 demonstrated clinically significant improvements in FEV1 with no clinically relevant safety concerns.

MediciNova acquired an exclusive, worldwide (excluding Japan), sublicensable license to MN-221 from Kissei Pharmaceutical Co., Ltd. The intellectual property acquired from Kissei includes extensive preclinical and clinical safety data.
