Summary

This prospective, single-arm, multicenter, exploratory study will enroll 38 adults patients with newly diagnosed primary immune thrombocytopenia (ITP). Patients will receive standard-dose corticosteroids plus a thrombopoietin receptor agonist (TPO-RA) as initial therapy During the core treatment phase (Weeks 1-12). Corticosteroids will be tapered and discontinued within 8 weeks, whereas TPO-RA treatment will continue for 12 weeks. For patients with treatment failure( defined as platelet count \< 30 × 10\^9/L or less than 2-fold increase of baseline platelet count or bleeding) ,a sequential multitarget combination strategy will be explored in subsequent treatment phases. Specifically, patients with treatment failure after 2 weeks of initial therapy (Weeks 3-12), will receive the ongoing TPO-RA in combination with either rituximab or an anti-CD38 monoclonal antibody(mAb) as sequential combination therapy.

During the core treatment follow-up phase (24 weeks), patients with treatment failure will enter the exploratory treatment phase (Weeks 13-36) .

Patients who received multi-target drug therapy during the core treatment period will switch to an alternative TPO-RA with cross-administered rituximab and anti-CD38 mAb, while those who did not will receive sequential rituximab or anti-CD38 mAb.

Finally, patients will enter the safety follow up period (4 weeks, weeks 37-40).

Conditions

  • ITP - Immune Thrombocytopenia

Interventions

DRUG

standard-dose methylprednisolone/prednisone.

Methylprednisolone 0.8-1mg/kg/day administered intravenously or orally; or prednisone 1 mg/kg/day, up to a maximum dose of 80 mg/day

DRUG

thrombopoietin receptor agonist(TPO-RA), including but not limited to hetrombopag or eltrombopag.

Dosing will follow the recommended dose in the prescribing information; in severe ITP, the initial dose will be selected according to BAT (best available therapy) principles.

DRUG

rituximab.

Administered as 375 mg/m² by intravenous infusion for a single dose, or 100 mg by intravenous infusion once weekly for a total of 4 doses.

DRUG

Daratumumab

Administered at 16 mg/kg by intravenous infusion once weekly for a total of 4-8 doses.
