What are some specific safety events to monitor for?
Thrombotic/Thromboembolic complications1
- In clinical trials in patients with chronic ITP, 7% (9/128) of patients treated with Doptelet developed a thromboembolic event
- 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
- Monitor platelet counts and follow the dosing guidelines to achieve target platelet counts. Monitor patients receiving Doptelet for signs and symptoms of thromboembolic events and institute treatment promptly
Serious adverse reactions1
- Occurred more frequently in patients with chronic ITP treated with Doptelet (9%; 12/128); included headache, occurring in 1.6% (2/128)
- Adverse reactions resulting in discontinuation of Doptelet that were reported in more than 1 patient included headache, occurring in 1.6% (2/128)
*Doptelet had no significant liver damage reported in clinical trials. Therefore, no additional liver function monitoring is required.2
ITP=immune thrombocytopenia.
