SAN DIEGO, Jan. 07, 2019 (GLOBE NEWSWIRE) —  La Jolla Pharmaceutical Company (Nasdaq: LJPC), a leader in the discovery, development and commercialization of innovative therapies intended to significantly improve outcomes in patients suffering from life-threatening diseases, today highlighted recent corporate progress and key objectives.

Recent Corporate Progress and Key Objectives

GIAPREZATM (angiotensin II)

  • Fourth-Quarter 2018 Net Sales: Fourth-quarter 2018 net sales were approximately $4.2 million, up 20% from the third quarter of 2018.
  • 2018 Net Sales: 2018 net sales were approximately $10.1 million. GIAPREZA was launched in March 2018.
  • Full-Year 2019 Net Sales Guidance: La Jolla expects full-year 2019 net sales of $24 million to $28 million.
  • Decision on GIAPREZA MAA by EMA Expected in June of 2019: La Jolla expects a decision on the GIAPREZA Marketing Authorisation Application (MAA) by the European Medicines Agency (EMA) in June of 2019.

Investigational Products Update

  • NDA Planned for New Investigational Product, LJPC-0118, for the Treatment of Severe Malaria, in Fourth Quarter of 2019: La Jolla plans to file a New Drug Application (NDA) with the U.S. Food and Drug Administration (FDA) in the fourth quarter of 2019 for LJPC-0118. LJPC-0118 is La Jolla’s new investigational product for the treatment of severe malaria. The active pharmaceutical ingredient in LJPC-0118 was demonstrated to be superior to quinine in reducing mortality in patients with severe falciparum malaria infection in two randomized, controlled, clinical studies.
  • Topline Results of Phase 2 Study of LJPC-401 in Patients with Hereditary Hemochromatosis Expected in Second Half of 2019: La Jolla expects topline results in the second half of 2019 for LJ401-HH01, a multinational, multicenter, randomized, Phase 2 study that is designed to evaluate the safety and efficacy of LJPC-401, La Jolla’s proprietary formulation of synthetic human hepcidin, as a treatment for hereditary hemochromatosis (HH). The primary efficacy endpoint of the study is the change in transferrin saturation, a standard measurement of iron levels in the body and one of the two key measurements used to detect iron overload, from baseline to end of treatment.              
  • Topline Results of Pivotal Study of LJPC-401 in Patients with Beta Thalassemia Expected in Mid-2020: La Jolla expects topline results in mid-2020 for LJ401-BT01, a pivotal, multinational, multicenter, randomized, controlled study that is designed to evaluate the safety and efficacy of LJPC-401 as a treatment for beta thalassemia (BT) patients who, despite chelation therapy, have cardiac iron levels above normal. The primary efficacy endpoint of this study is the change in iron content in the heart after 6 months, as measured by cardiac magnetic resonance imaging (MRI). If this study is successful, La Jolla anticipates filing an MAA for LJPC-401 in the European Union (EU).

             
As of December 31, 2018, La Jolla had approximately $172 million in cash and cash equivalents and no debt. In 2019, La Jolla expects that its net cash used in operating activities will be $89 million to $94 million.

“We are excited to have launched GIAPREZA, our first commercial product, in 2018. We believe that GIAPREZA has the potential to help many patients suffering from septic or other distributive shock, and we have a number of initiatives that we believe will support its continued, increased adoption in 2019,” said George Tidmarsh, M.D., Ph.D., La Jolla’s President and Chief Executive Officer. “Our two randomized studies of LJPC-401 in BT and HH have the potential to demonstrate improved patient outcomes in these important diseases. Furthermore, we are excited to announce a planned NDA submission for LJPC-0118, our new investigational product for the treatment of severe malaria, in the fourth quarter of 2019.”

About GIAPREZA

In December 2017, GIAPREZA™ (angiotensin II) was approved by the U.S. Food and Drug Administration (FDA) as a vasoconstrictor 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. Prescribing information for GIAPREZA is available at www.giapreza.com. GIAPREZA is marketed by La Jolla Pharmaceutical Company on behalf of La Jolla Pharma, LLC, its wholly owned subsidiary.

IMPORTANT SAFETY INFORMATION

Contraindications

None

Warnings and Precautions

There is a potential for venous and arterial thrombotic and thromboembolic events in patients who receive GIAPREZA. Use concurrent venous thromboembolism (VTE) prophylaxis.

Adverse Reactions

The most common adverse reactions that were reported in greater than 10% of GIAPREZA-treated patients were thromboembolic events.

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.

About LJPC-0118

LJPC-0118 is La Jolla’s investigational product for the treatment of severe malaria. The active pharmaceutical ingredient in LJPC-0118 was demonstrated to be superior to quinine in reducing mortality in patients with severe falciparum malaria infection in two randomized, controlled, clinical studies. La Jolla plans to file a New Drug Application (NDA) with the U.S. Food and Drug Administration (FDA) in the fourth quarter of 2019 for LJPC-0118. Severe malaria is a serious and sometimes fatal disease caused by a parasite that commonly infects a certain type of mosquito, which feeds on humans. Symptoms include but are not limited to: fever, chills, sweating, hypoglycemia and shock. Severe malaria is often complicated by central nervous system infections that may lead to delirium, which may progress to coma. Infections usually occur a few weeks after being bitten. In 2017, an estimated 219 million cases of malaria occurred worldwide, with an estimated 200 million of these cases occurring in the World Health Organization (WHO) African Region, and, in 2013, the global annual incidence of severe malaria was estimated to be 2 million cases. In 2017, an estimated 435,000 people died from malaria worldwide.

About LJPC-401

LJPC-401, a clinical-stage investigational product, is La Jolla’s proprietary formulation of synthetic human hepcidin. Hepcidin, an endogenous peptide hormone, is the body’s naturally occurring regulator of iron absorption and distribution. In healthy individuals, hepcidin prevents excessive iron accumulation in vital organs, such as the liver and heart, where it can cause significant damage and even result in death. La Jolla is developing LJPC-401 for the potential treatment of iron overload, which occurs as a result of primary iron overload diseases such as hereditary hemochromatosis (HH), or secondary iron overload diseases such as beta thalassemia, sickle cell disease (SCD) and myelodysplastic syndrome (MDS). The European Medicines Agency (EMA) Committee for Orphan Medicinal Products (COMP) has designated LJPC‑401 as an orphan medicinal product for the treatment of beta thalassemia intermedia and major and SCD.
