Dova Pharma Announces New Drug Application Submission To FDA For Avatrombopag, A Second Generation Thrombopoietin Receptor Agonist
Published: Sep 22, 2017
DURHAM, N.C., Sept. 22, 2017 (GLOBE NEWSWIRE) -- Dova Pharmaceuticals, Inc. (NASDAQ:DOVA), a specialty pharmaceutical company, today announced the submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for avatrombopag, a second generation orally administered thrombopoietin receptor agonist (TPO-RA) for the treatment of thrombocytopenia in patients with chronic liver disease (CLD) who are scheduled to undergo a procedure.
"Submission of the NDA for avatrombopag represents a significant milestone and a major advancement towards potentially bringing this novel therapy to patients, including the approximately 1.1 million CLD patients in the United States affected by thrombocytopenia, of whom approximately 70,000 have severe thrombocytopenia," said Alex Sapir, President and CEO of Dova. "The treatment of thrombocytopenia represents an important unmet need in this patient population, as significant limitations impact the use of platelet transfusions, the current standard of care.” Risks associated with platelet transfusions include antibody development, bacterial infections, short duration of effect, limited supply, and inconvenience of administration. Currently there is no drug treatment approved by FDA or the European Medicines Agency (EMA) for the treatment of thrombocytopenia in patients with CLD who are scheduled to undergo a procedure.
Primary safety and efficacy data supporting the NDA submission were provided by the results of two pivotal Phase 3 clinical trials, ADAPT-1 and ADAPT-2, that evaluated the efficacy and safety of avatrombopag for the treatment of severe thrombocytopenia (defined as <50,000 platelets per microliter of circulating blood) in patients with CLD. In both trials, avatrombopag met the primary and secondary efficacy endpoints with high statistical significance. Avatrombopag treatment was well tolerated with a safety profile that was generally comparable to that of placebo, with the frequency, severity, and types of adverse events reported being consistent with those expected in patients with CLD. There will be an oral presentation of these two pivotal Phase 3 trials at the upcoming American Association for the Study of Liver Diseases (AASLD) Meeting in Washington, DC on October 23rd at 3PM (EDT).
Avatrombopag is a second generation orally administered TPO-RA which is intended to address the limitations of other existing treatments for thrombocytopenia. In two identically-designed Phase 3 clinical trials, ADAPT 1 and ADAPT 2, avatrombopag met all primary and secondary endpoints with high statistical significance. Avatrombopag is initially being studied for its potential for the acute treatment of thrombocytopenia in patients with CLD scheduled to undergo a procedure. Dova is also planning to explore the potential use of avatrombopag in a broader population of patients with thrombocytopenia, including in patients undergoing surgical procedures associated with a high risk of bleeding, and patients who develop thrombocytopenia after receiving chemotherapy. In addition, Dova is exploring a potential regulatory approval pathway for avatrombopag for the treatment of adults with chronic immune thrombocytopenic purpura (ITP) based on results from a completed Phase 3 trial in this patient population. Dova holds the worldwide rights to avatrombopag for all current and future indications.
