Item 8.01                     Other Events.

On May 18, 2011, La Jolla Pharmaceutical Company (the “Company”) received preliminary data from Charles River Laboratories, the Company’s clinical research organization (the “CRO”), regarding the confirmatory pre-clinical study of the Company’s LJP1485 compound being studied for tissue regeneration (the “Preclinical Study”). Based on the preliminary data from the Preclinical Study, the Company expects that the predetermined study endpoints, as set forth on the Purchase Agreement (defined below), will not be met and that the LJP1485 compound will not show statistically significant improvement in the study endpoints as compared to vehicle (placebo).

The Company expects the CRO to issue its final report on the Preclinical Study (the “Study Report”) on or about May 25, 2011. If the Company’s existing holders of Series C-11 Convertible Preferred Stock (the “Preferred Stockholders”) do not exercise their cash warrants (the “Cash Warrants”) within five days from their receipt of the Study Report, as contemplated in the Purchase Agreement, then GliaMed, Inc. will have the right under the Purchase Agreement to reacquire the 1485 compound and all related assets in consideration for paying the Company a nominal cash sum. The Preferred Stockholders will have no obligation to exercise the Cash Warrants if the Study Report concludes that the endpoints were not met, which we expect will be the case.

Unless and until the Preferred Stockholders exercise the Cash Warrants, the Preferred Stockholders have the right to require the Company to redeem all outstanding shares of Series C-11 Convertible Preferred Stock for an aggregate sum of approximately $5.4 million. If the Preferred Stockholders exercise these redemption rights, the Company would have insufficient cash to sustain its operations and the Company would likely need to wind down all activities.

The Preclinical Study was being conducted pursuant the Asset Purchase Agreement, dated March 29, 2011, by and among the Company, Jewel Merger Sub, Inc. and GliaMed, Inc. (the “Purchase Agreement”). Additional information relating to the Purchase Agreement can be found in the Company’s Current Report on Form 8-K filed on April 5, 2011.
