La Jolla Pharmaceutical Company Announces the Treatment of First Patient in GIAPREZA™ (angiotensin II) Pediatric Study

SAN DIEGO, Feb. 21, 2018 (GLOBE NEWSWIRE) -- La Jolla Pharmaceutical Company (Nasdaq:LJPC) today announced that the first pediatric patient has been treated in LJ501-CRH02, La Jolla’s open-label study of GIAPREZATM (angiotensin II), injection for intravenous infusion, in pediatric patients (ages 2-17) with shock who remain hypotensive despite receiving fluid and current standard-of-care vasopressor therapy.

LJ501-CRH02 is an open-label study that will enroll approximately 30 patients in 10 pediatric intensive care units across the United States. The primary objective of this study is to evaluate the effect of GIAPREZA on mean arterial pressure (MAP) or total norepinephrine (NE)-equivalent dosing, two hours after the initiation of GIAPREZA.

“We are thrilled to enroll the first pediatric patient in this open-label study of angiotensin II in children with vasodilatory septic or other distributive shock,” said Dwight Bailey, D.O., Specialty Medical Director, Pediatric Critical Care Medicine Division, Atrium Health’s Levine Children’s Hospital in Charlotte, North Carolina. “The critical care team and the patient’s family were grateful to have another option for the treatment of this young patient who we believe was suffering from influenza, which was complicated by a bacterial superinfection and septic shock, especially given the limited therapeutic options for pediatric patients.”

In December 2017, GIAPREZA was approved by the U.S. Food and Drug Administration (FDA) to increase blood pressure in adults with septic or other distributive shock. GIAPREZA (angiotensin II) mimics the body’s endogenous regulatory peptide that is central to the renin-angiotensin-aldosterone system to increase blood pressure.

About Patients with Septic or Other Distributive Shock Failing Standard Therapy

Septic or other distributive shock (dangerously low blood pressure with adequate cardiac function) can become life threatening when a patient is unable to achieve target mean arterial pressure (MAP) despite adequate fluid resuscitation and treatment with other available vasopressors (catecholamines and/or vasopressin). Distributive shock is the most common type of shock in the inpatient setting. Shock is prevalent, affecting 1 in 3 intensive care unit patients. There are approximately 800,000 distributive shock cases in the United States each year. Of these cases, an estimated 90% are septic shock patients. Approximately 300,000 of these patients do not achieve adequate blood pressure response with fluids and typical, first-line catecholamine therapy. The inability to achieve or maintain adequate blood pressure results in inadequate blood flow to the body’s organs and tissue and is associated with organ damage and a mortality rate exceeding most acute conditions requiring hospitalization.

About GIAPREZA

In December 2017, GIAPREZATM (angiotensin II) was approved by the U.S. Food and Drug Administration (FDA) to increase blood pressure in adults with septic or other distributive shock. GIAPREZA (angiotensin II) mimics the body’s endogenous regulatory peptide that is central to the renin-angiotensin-aldosterone system to increase blood pressure. In the ATHOS-3 Phase 3 study, the primary endpoint of: (i) a mean arterial pressure (MAP) increase of ≥ 10 mmHg; or (ii) a MAP of ≥ 75 mmHg, was achieved by 70% of patients randomized to GIAPREZA, compared to 23% of patients randomized to placebo (p < 0.0001); both arms were treated with standard-of-care vasopressors. The recommended starting dosage of GIAPREZA is 20 nanograms (ng)/kg/min via continuous intravenous infusion. Close monitoring during the first 5 minutes of GIAPREZA initiation is recommended. GIAPREZA is available as a carton of 1 mL single dose vials, each containing 2 mg of angiotensin II (as a sterile liquid). Prescribing information for GIAPREZA is available at www.giapreza.com.

IMPORTANT SAFETY INFORMATION

Warnings and Precautions

The safety of GIAPREZA was evaluated in 321 adults with septic or other distributive shock in the randomized, double-blind, placebo-controlled ATHOS-3 Phase 3 study. There was a higher incidence of venous and arterial thromboembolic events in patients who received GIAPREZA compared to placebo-treated patients in the Phase 3 study [13% (21/163 patients) vs. 5% (8/158 patients)]. The major imbalance was in venous thrombosis. Use concurrent venous thromboembolism prophylaxis.

Adverse Reactions

Adverse reactions that occurred in ≥4% of patients treated with GIAPREZA and ≥1.5% more often than placebo-treated patients in the ATHOS-3 study were thromboembolic events (including deep vein thrombosis), thrombocytopenia, tachycardia, fungal infection, delirium, acidosis, hyperglycemia and peripheral ischemia.

Drug Interactions

Angiotensin converting enzyme (ACE) inhibitors may increase response to GIAPREZA.
Angiotensin II receptor blockers (ARB) may reduce response to GIAPREZA.
