Amivas (US), LLC Announces U.S. Launch of Artesunate for Injection for Initial Treatment of Severe Malaria
FREDERICK, Md., March 30, 2021 /PRNewswire/ -- Amivas (US), LLC, specialists in treatments for rare and neglected tropical diseases, including severe malaria, announced today the U.S. launch of Artesunate for Injection 110 mg, powder and solvent for solution.
Artesunate for Injection is available for order via:
Indicated for the initial treatment of severe malaria in adult and pediatric patients, Artesunate for Injection received marketing approval by the U.S. Food and Drug Administration (FDA) on May 26, 2020. Artesunate for Injection is the first FDA-approved product that Amivas, headquartered in Frederick, Maryland, has introduced to its commercial portfolio.
"Amivas is excited to now manufacture, distribute, and commercialize Artesunate for Injection on an exclusive basis through a network of select distributors across the U.S.," said Amivas (US), LLC Chief Executive Officer, David Bradshaw. "This is an entirely new system designed to save lives by ensuring that patients who need Artesunate for Injection have rapid access to it at any time of day or night, every day of the year."
Prior to FDA approval, access to investigational IV Artesunate had been managed by the Centers for Disease Control and Prevention (CDC) since 2007 via an expanded access investigational new drug (IND) program.
"For a patient diagnosed with severe malaria, nothing is more important than receiving safe, efficacious, fast-acting injectable treatment without delay," said Bryan Smith, M.D., Chief Medical Officer at Amivas. "Since receiving FDA approval of this life-saving product last year, our entire effort has centered on building a robust network of U.S. distribution partners so that any U.S. patient with severe malaria can receive Artesunate for Injection on demand. Our expertise is in helping patients and our focus is on time. The launch of Artesunate for Injection is an exciting and gratifying milestone to reach."
Hospitals may now stock Amivas' Artesunate for Injection for immediate treatment of patients with severe malaria to prevent poor outcomes such as death.
Healthcare professionals who require medical consultation on how to treat a patient who has severe malaria, or who are unable to secure an emergency shipment of Artesunate for Injection via the usual distribution channels within 24 hours, should contact the CDC (www.cdc.gov/malaria/diagnosis_treatment/artesunate.html (770-488-7788) Monday – Friday, 9:00 am EST – 5:00 pm EST. Outside these hours, healthcare providers should call 770-488-7100).
On an as-needed basis, the CDC will continue to support the distribution of artesunate under an expanded use IND protocol, including in those few locations where Artesunate for Injection is still being fully stocked by Amivas.
Development of Artesunate for Injection in the U.S. has been under U.S. Army Medical Research and Development Command (USAMRDC). Within USAMRDC, the Walter Reed Army Institute of Research and the U.S. Army Medical Materiel Development Activity (USAMMDA) joint collaborative work has provided the CDC a constant supply of IV artesunate since 2007. USAMMDA established a cooperative research and development agreement with Amivas to modernize Artesunate manufacture and register the product with the FDA.
Approximately 2,000 U.S. cases of malaria are diagnosed annually. Without appropriate treatment, about 15 percent become severe. Mortality from untreated severe malaria (particularly cerebral malaria) approaches 100 percent.
Important Safety Information
Warnings and Precautions
Post Artesunate Delayed Hemolysis: Post-artesunate delayed hemolysis is characterized by decreased hemoglobin with laboratory evidence of hemolysis (such as decreased haptoglobin and increased lactate dehydrogenase) occurring at least 7 days after initiating artesunate treatment. Cases of post-treatment hemolytic anemia severe enough to require transfusion have been reported. Monitor patients for 4 weeks after artesunate treatment for evidence of hemolytic anemia. Since a subset of patients with delayed hemolysis after artesunate therapy have evidence of immune-mediated hemolysis, consider performing a direct antiglobulin test to determine if therapy, e.g., corticosteroids, is necessary.
Hypersensitivity reactions: Hypersensitivity to artesunate including cases of anaphylaxis have been reported during the use of parenteral artesunate (including Artesunate for Injection). If hypotension, dyspnea, urticaria, or generalized rash occur during administration of Artesunate for Injection, consider discontinuing Artesunate for Injection administration and continuing therapy with another antimalarial drug.
The most common adverse reactions (2 percent or greater) occurring more frequently in patients receiving intravenous artesunate in the SEAQUAMAT trial were acute renal failure requiring dialysis, hemoglobinuria, and jaundice. The most common adverse reactions in the CDC expanded access protocol were anemia (65 percent), transaminase increase (27 percent), thrombocytopenia (18 percent), hyperbilirubinemia (14 percent), acute renal failure (10 percent), leukocytosis (10 percent), acute respiratory distress syndrome (8 percent), lymphopenia (7 percent), neutropenia (5 percent), disseminated intravascular coagulation (3 percent), elevated creatinine (3 percent), pneumonia (3 percent), pulmonary edema (3 percent), and diarrhea (3 percent).
Published reports of in vitro data indicate that concomitant use of Artesunate for Injection with UGT inhibitors may increase DHA AUC and Cmax, which may increase DHA associated adverse reactions. Monitor for adverse reactions when co-administering Artesunate for Injection with strong UGT inhibitors (e.g., axitinib, vandetanib, imatinib, diclofenac).
Use in Specific Populations
Pediatric Use: The safety and effectiveness of Artesunate for Injection for the treatment of severe malaria have been established in pediatric patients.
Geriatric Use: Clinical studies of Artesunate for Injection did not include sufficient numbers of patients aged 65 years and older to determine whether they respond differently than younger subjects.

About Malaria and Severe Malaria
Prompt, effective treatment within 24 - 48 hours of the onset of malaria symptoms is necessary.
Malaria is a rare disease in the U.S. Therefore, it is not always recognized, diagnosed and treated in timely fashion. Nearly all cases in the US occur in persons who acquire the infection while in a malaria endemic area and who are diagnosed after returning to the US. Most are U.S. residents with no acquired immunity to malaria and who are, therefore, at risk of developing severe malaria. A major contributing factor to continued malaria-associated mortality in the U.S. is delay in initiation of appropriate treatment. Malaria chemoprophylaxis and the use of bed nets and insect repellants help reduce the risk of contracting malaria.
