SAN DIEGO, Feb. 25, 2018 (GLOBE NEWSWIRE) -- La Jolla Pharmaceutical Company (Nasdaq:LJPC) today announced that an abstract, entitled “Effect of Disease Severity on Survival in Patients Receiving Angiotensin II for Vasodilatory Shock,” will be presented at the Society of Critical Care Medicine’s (SCCM) 47th Critical Care Congress, being held from February 25 to 28, 2018 in San Antonio, Texas.

The abstract, which was published in the January Supplement of Critical Care Medicine and online, includes results from a pre-specified analysis from the ATHOS-3 (Angiotensin II for the Treatment of High Output Shock) Phase 3 study of GIAPREZATM (angiotensin II) in patients with high severity of illness, defined as an APACHE II (Acute Physiology and Chronic Health Evaluation II) score > 30 or baseline MAP < 65 mmHg, despite treatment with high-dose vasopressors. The authors present data showing a lower 28-day mortality rate in patients with baseline APACHE II scores > 30 in the GIAPREZA group versus the placebo group: 28-day mortality was 51.8% (n = 58) for the GIAPREZA group compared to 70.8% (n = 65) for the placebo group (hazard ratio=0.62 [95% CI: 0.39, 0.98; p=0.037]). In patients with a baseline MAP < 65 mmHg, a trend towards improved 28-day mortality was seen in the GIAPREZA group compared to the placebo group: 28-day mortality was 54.2% (n = 52) for the GIAPREZA group compared to 70.4% (n = 50) for the placebo group (hazard ratio=0.66 [95% CI: 0.40, 1.09; p=0.10]).

About GIAPREZA

In December 2017, GIAPREZA™ (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 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 in 1 mL single dose vials, each containing 2.5 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 thrombotic and thromboembolic events in patients who received GIAPREZA compared to placebo-treated patients in the ATHOS-3 study [13% (21/163 patients) vs. 5% (8/158 patients)]. The major imbalance was in deep venous thromboses. 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.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.
