Description

Avatrombopag is an orally bioavailable, small molecule thrombopoietin (TPO) receptor agonist that stimulates proliferation and differentiation of megakaryocytes from bone marrow progenitor cells resulting in increased production of platelets. Avatrombopag does not compete with TPO for binding to the TPO receptor and has an additive effect with TPO on platelet production. Avatrombopag was discovered by Yamanouchi Pharmaceutical, developed by AkaRx which late became acquired by Dova Pharmaceuticals. In 2018 avatrombopag was approved by the FDA for thrombocytopenia in adults with chronic liver disease scheduled to undergo a procedure.

Sample Use Guides

In Vivo Use Guide
For patients with a platelet count 40000 to <50000/mm3: 40 mg once daily for 5 consecutive days, orally. For patients with platelet count below 40,000/mm3: 60 mg once daily for 5 consecutive days.
Route of Administration: Oral
In Vitro Use Guide
Avatrombopag stimulated the proliferation of cells expressing the human thrombopoietin receptor (c-Mpl) with an EC50 value of 3.3 nM and promoted the differentiation of human hematopoietic progenitor cells (cord blood CD34+ cells) to megakaryocytes with an EC50 value of 25.0 nM.
