Item 8.01                     Other Events.

On May 25, 2011, La Jolla Pharmaceutical Company (the “Company”) received the final report from Charles River Laboratories, the Company’s clinical research organization (the “CRO”), regarding the confirmatory preclinical study of the Company’s LJP1485 compound being studied for tissue regeneration (the “Preclinical Study”). Consistent with the preliminary results reported on the Company’s Current Report on Form 8-K filed on May 23, 2011 (the “Prior 8-K”), the CRO concluded that the predetermined study endpoints, as described in the Prior 8-K, had not been met.

Based on the timing of the final study report, the Company’s existing holders of Series C-11 Convertible Preferred Stock (the “Preferred Stockholders”) will have until June 2, 2011 to exercise their cash warrants (the “Cash Warrants”), as described in the Prior 8-K. If the Cash Warrants are not fully exercised by this date, then GliaMed, Inc. will have the right to reacquire the 1485 compound and all related assets in consideration for paying the Company a nominal cash sum. The Preferred Stockholders have no obligation to exercise the Cash Warrants given that the Preclinical Study was not successful.

Investors are urged to read the Prior 8-K for additional information regarding the Preclinical Study and the potential impact on the Company of the failure to achieve the study endpoints.
