Item 7.01 Regulation FD Disclosure

On August 25, 2009, The Pennsylvania Funds filed a class action lawsuit in the Superior Court of the State of California, County of Alameda, purportedly on behalf of the stockholders of Avigen, Inc., against Avigen and its directors, alleging that Avigen’s directors breached their fiduciary duties to the stockholders of Avigen in connection with the proposed acquisition of Avigen by MediciNova, Inc. The complaint seeks to enjoin the defendants from completing the acquisition as currently contemplated.

Avigen and its directors intend to take all appropriate actions to defend the suit.

It is possible that additional similar complaints may be filed in the future. If this does occur, Avigen does not intend to announce the filing of any similar complaints unless they contain allegations that are substantially distinct from those made in the pending action.
