San Diego’s MediciNova Nears Turning Point with Lead Drug for Asthma

[Corrected 5/7/12, 5:10 pm. See below.] When Yuichi Iwaki started MediciNova in 2000, he says many mid-size pharmaceutical companies in Japan had concluded it was just too difficult to conduct their own clinical trials in the United States. So MediciNova was born of a kind of Japanese pragmatism.

Iwaki, a Japanese-trained surgeon who came to the United States in the 1980s, is particularly hopeful about MediciNova’s lead drug candidate, bedoradrine sulfate, a compound licensed from Japan’s Kissei Pharmaceutical for use in the United States as an intravenous treatment for treating acute asthma attacks.

MediciNova says its drug has a key advantage over the current standard of care in U.S. emergency rooms, which typically use an inhaled drug like albuterol. An asthma patient’s constricted airways can limit the effectiveness of aerosol drugs, which creates some uncertainty over how much of a given drug has been absorbed. Because bedoradrine is delivered … Next Page »
