Item 8.01    Other Events.

On July 8, 2014, La Jolla Pharmaceutical Company (the “Company”) announced that the Company plans to begin a phase 3 registration program for LJPC-501 (angiotensin II) for the treatment of catecholamine-resistant hypotension (CRH), a new indication. Initiation of this registration program is the result of a recent meeting between the Company and the U.S. Food and Drug Administration at which agreement was reached that blood pressure could serve as an appropriate primary endpoint for approval.

Hypotension, if uncorrected, is life-threatening and occurs as the result of various underlying conditions such as blood loss due to trauma, septic shock, poor heart function or drug reactions. The first line of treatment is catecholamine infusion. Catecholamines are derived from the amino acid tyrosine and include epinephrine (adrenaline), norepinephrine (noradrenaline), and dopamine, which act as neurotransmitters that increase blood pressure. While largely effective, some patients fail to respond to adequate doses and are defined as catecholamine-resistant.

LJPC-501 is a peptide agonist of the renin-angiotensin system that acts to stabilize blood pressure. One of the most widely prescribed classes of blood pressure medication, angiotensin converting enzyme inhibitors, inhibits the production of angiotensin II, thereby reducing blood pressure.

Due to the estimated size of the patient population in the United States for this indication, the Company has filed for Orphan Drug status for LJPC-501 for the treatment of CRH.
