Pomalidomide, Rituximab and Orelabrutinib Combined With Polatuzumab Vedotin in the Treatment of Newly Diagnosed Elderly Patients With DLBCL

Официальное название

A Prospective and Exploratory Clinical Study of Pomalidomide, Rituximab and Orelabrutinib Combined With Polatuzumab Vedotin in the Treatment of Newly Diagnosed Elderly Patients With DLBCL

Обзор

To evaluate the efficacy and safety of the Pro-Pola （Pomalidomide, rituximab, orelabrutinib and polatuzumab vedotin) regimen in elderly patients (aged ≥70 years) with newly diagnosed diffuse large B-cell lymphoma (DLBCL).

Подробное описание

The study will start with an initial 21-days of induction therapy with Pro regimen (Pomalidomide, rituximab and orelabrutinib)，following imaging examinations to evaluate response rates. Patients with a lesion reduction of ≥25% received Pro-pola(Pro regimen plus polatuzumab vedotin), in a 21-day cycle for 6 cycles.

• Препарат Induction therapy-Pro regimen
  Pro regimen induction(21days per cycle\*1 cycle) * Pomalidomide 4mg per tablet 4mg orally from Days 1 to 7 of each cycle * Rituximab 100mg per vial 375mg/m2, intravenous drip, Day 1 of each cycle * Orelabrutinib 50mg per tablet 150mg orally per day from Days 1 to 21 of each cycle
• Препарат Consolidation therapy-Pro-pola regimen
  Pro-pola regimen consolidation(21days per cycle\*6 cycle) -Pomalidomide 4mg per tablet 4mg orally from Days 1 to 7 of each cycle -Rituximab 100mg per vial 375mg/m2, intravenous drip, Day 1 of each cycle -Orelabrutinib 50mg per tablet 150mg orally per day from Days 1 to 21 of each cycle -Polatuzumab vedotin 30mg per vial 1.8 mg/kg, intravenous drip, Day 1 of each cycle
