Chronic immune thrombocytopenia (ITP) in adult patients who have had an insufficient response to a previous treatment
Initial criteria
- Member has an inadequate response or intolerance to prior therapy (e.g., corticosteroids, immunoglobulins)
- Member has an untransfused platelet count at any point prior to the initiation of the requested medication of either of the following: less than 30x10^9/L; 30x10^9/L to 50x10^9/L with symptomatic bleeding (e.g., significant mucous membrane bleeding, gastrointestinal bleeding or trauma) or risk factors for bleeding (see Appendix)
- Medication must be prescribed by or in consultation with a hematologist

Reauthorization criteria

- Authorization of 12 months may be granted to members with current platelet count less than 50x10^9/L for whom the current platelet count is sufficient to prevent clinically important bleeding
- Authorization of 12 months may be granted to members with current platelet count of 50x10^9/L to 200x10^9/L
- Authorization of 12 months may be granted to members with current platelet count greater than 200x10^9/L to less than or equal to 400x10^9/L for whom Tavalisse dosing will be adjusted to achieve a platelet count sufficient to avoid clinically important bleeding
