An ITP Case Study in a Patient Who Is Non-responsive to Multiple Courses of Steroids
INDICATION
DOPTELET® (avatrombopag) is indicated for the treatment of thrombocytopenia in adult patients with chronic immune thrombocytopenia who have had an insufficient response to a previous treatment.
IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Thrombotic/Thromboembolic Complications. DOPTELET is a thrombopoietin (TPO) receptor agonist and TPO receptor agonists have been associated with thrombotic complications in patients with chronic liver disease (0.4%; (1/274) in DOPTELET-treated patients) and thromboembolic complications in patients with chronic immune thrombocytopenia (7%; (9/128) in DOPTELET-treated patients). Portal vein thrombosis has been reported in patients with chronic liver disease, and thromboembolic events (arterial and venous) have been reported in patients with chronic immune thrombocytopenia treated with TPO receptor agonists.
Consider the potential increased thrombotic risk when administering DOPTELET to patients with known risk factors for thromboembolism, including genetic prothrombotic conditions and acquired risk factors.
DOPTELET should not be administered to patients with chronic liver disease or chronic immune thrombocytopenia in an attempt to normalize platelet counts. Monitor platelet counts, and for signs and symptoms of thromboembolic events and institute treatment promptly.
Serious Adverse Reactions
Serious adverse reaction that occurred more frequently in patients treated with DOPTELET (9%; 12/128) compared to placebo (5%; 1/22) was headache, occurring in 1.6% (2/128).
Adverse Reactions
The most common adverse reactions (≥10%) in patients with chronic immune thrombocytopenia were headache, fatigue, contusion, epistaxis, upper respiratory tract infection, arthralgia, gingival bleeding, petechiae, and nasopharyngitis.
Postmarketing Experience
Following the approval of DOPTELET, hypersensitivity reactions involving the immune system, including, but not limited to, pruritus, rash, choking sensation, swollen face, and swollen tongue have been reported.
These are not all the possible risks associated with DOPTELET. Please see Full Prescribing Information for DOPTELET at www.doptelethcp.com
