La Jolla Pharmaceutical Company Announces First Quarter 2015 Financial Results and Corporate Highlights

La Jolla Pharmaceutical Company (NASDAQ: LJPC) (the Company or La Jolla), a leader in the development of innovative therapies intended to significantly improve outcomes in patients suffering from life-threatening diseases, today reported first quarter 2015 financial results and highlighted recent corporate progress and near-term milestones.

Recent Corporate Highlights

• La Jolla reached agreement with the U.S. Food and Drug Administration (FDA) on a Special Protocol Assessment (SPA) for its ATHOS 3 trial, in which the agreed-upon primary efficacy endpoint is increase in blood pressure.
• The ATHOS (Angiotensin II for the Treatment of High-Output Shock) 3 trial, La Jolla’s multicenter, randomized, double-blind, placebo-controlled, Phase 3 clinical trial of LJPC-501, La Jolla’s proprietary formulation of angiotensin II, in catecholamine-resistant hypotension (CRH) was initiated in March 2015.
• La Jolla’s multicenter, randomized, double-blind, placebo-controlled, Phase 2b clinical trial of GCS-100, La Jolla’s first-in-class galectin-3 inhibitor, in diabetic patients with Stage 3b or 4 Chronic Kidney Disease (CKD) was initiated in March 2015.
• The executive team of La Jolla was strengthened with the appointment of Lakhmir Chawla, M.D. as its Chief Medical Officer and Dennis Mulroy as its Chief Financial Officer.
• La Jolla added four new members, Paul Adams, M.D., Victor Gordeuk, M.D., Ashutosh Lal, M.D. and Gordon McLaren, M.D., to its advisory board for the development of LJPC-401, La Jolla’s novel formulation of hepcidin.

“The first quarter was an exciting start to 2015 for La Jolla, highlighted by the initiation of both our LJPC-501 Phase 3 registration trial and our Phase 2b clinical trial of GCS-100 in advanced CKD patients,” said George Tidmarsh, M.D., Ph.D., La Jolla’s President and Chief Executive Officer. “With the recent strengthening of our executive team and the LJPC-401 advisory board, we look forward to building upon our recent progress and continuing the advancement of all of our programs, including the initiation of Phase 1 clinical trials for both LJPC-1010 and LJPC-401 later this year.”

Results of Operations

At March 31, 2015, La Jolla had $42.7 million in cash, compared to $48.6 million at December 31, 2014. The decrease in cash was primarily due to cash used for operating activities for the three months ended March 31, 2015. La Jolla’s net loss for the three months ended March 31, 2015 was $9.0 million, or $0.59 per share, compared to a net loss of $5.1 million, or $0.93 per share, for the same period in 2014. The increase in net loss was primarily due to increased clinical development costs associated with the initiation of our ATHOS 3 trial, the initiation of our Phase 2b clinical trial of GCS-100 in advanced CKD, the continuing Phase 1/2 clinical trial of LJPC-501 in HRS and preclinical costs associated with LJPC-1010 and LJPC-401, as well as increases in personnel and related costs, which were mainly due to additional headcount to support such increased development activities.
