Rapid and sustained efficacy:
In the pivotal, Phase 3, randomised study:
- Doptelet patients achieved a median of 12.4 weeks at or above target platelet count without rescue therapy over 6 months*1
- 65.6% of patients on Doptelet achieved the ≥50 x 109/L platelet target by day 8*1
Effective regardless of prior treatment experience
In a retrospective observational study:
- After switching to Doptelet from another TPO-RA, 88% of primary ITP patients reached the ≥50x109/L platelet target†2
Tolerability profile comparable to placebo
- Exposure-adjusted TEAEs 4.3% per patient week vs 6.6% with placebo*1
- Doptelet is the only oral TPO-RA that has not been associated with a significant hepatotoxicity signal in ITP clinical trials; no liver function monitoring is required as standard1,3
Doptelet can be taken with any food and no liver function monitoring is required as standard3
- Doptelet should be taken at the same time of day (e.g. in the morning or evening) with food, including when taking the dose less frequently than once daily1,3–5
- No liver function monitoring is required as standard1,3
*Vs 0.0% with placebo (P<0.0001), Phase 3 study.
†This study included patients with primary or secondary ITP; the figure quoted is for the primary ITP subgroup alone.
Doptelet is indicated for the treatment of primary chronic immune thrombocytopenia (ITP) in adult patients who are refractory to other treatments (e.g. corticosteroids, immunoglobulins).3
ITP, immune thrombocytopenia; TEAE, treatment-emergent adverse event; TPO-RA, thrombopoietin receptor agonist.
