MediciNova is developing MN-221, a highly selective
beta(2)-adrenergic receptor agonist, for the treatment of acute
exacerbations of asthma and COPD. In 2004, MediciNova licensed
exclusive rights to MN-221 from Kissei Pharmaceutical Co., Ltd. in
all territories except Japan.
Earlier, in May 2012, the company had presented preliminary data
from a hospital emergency department (ED)-based phase IIb trial of
MN-221 for the treatment of acute exacerbations of asthma. Although
the randomized, double-blind, placebo-controlled phase IIb trial
did not meet the primary endpoint, it was observed that the use of
MN-221 resulted in a significant improvement in clinical symptoms.
The company has scheduled an end-of-phase II meeting with the US
Food and Drug Administration (FDA) in late October 2012 regarding
the development of MN-221 for the treatment of acute exacerbations
of asthma. The company also plans to discuss the COPD data from the
phase Ib trial in this meeting.
MediciNova has a diversified pipeline, which includes 6
clinical-stage compounds targeting several indications including
respiratory disorders, neurologic conditions and oncology
conditions. However, we see no near-term catalyst for the stock.
Thus, we maintain a Neutral recommendation on MediciNova. The stock
carries a Zacks #3 Rank (Hold rating) in the short run.
