ITEM 5. Other Events and Regulation FD Disclosure.

     On June 7, 2001, Indevus Pharmaceuticals, Inc., formerly known as
Interneuron Pharmaceuticals, Inc. (the "Company"), issued a press release
containing the information attached hereto as Exhibit 99.1 announcing that
Pfizer Inc. ("Pfizer") will return to the Company exclusive, worldwide
development and commercialization rights to pagoclone, a drug in advanced
clinical stage testing to treat anxiety disorders. Pfizer also informed the
Company that the results of its most recent clinical trials with pagoclone in
generalized anxiety disorder and panic disorder did not achieve the level of
efficacy established in previous trials and accordingly, Pfizer has elected not
to pursue further development of pagoclone. The press release is incorporated
herein by reference.

     The exhibit hereto contains forward-looking statements that involve risks
and uncertainties that could cause our actual results and financial condition to
differ materially from those anticipated by the forward-looking statements. The
words "believe", "expect", "anticipate", "intend", "plan", "estimate" or other
expressions which are predictions of or indicate future events and trends do not

Company's filings under the Securities Act of 1933 and the Securities Exchange
Act of 1934 under "Risk Factors" and elsewhere in, or incorporated by reference
