Surovatamig come terapia di consolidamento in partecipanti con leucemia linfatica cronica o linfoma linfocitico a piccole cellule con catena pesante delle immunoglobuline variabile (IGHV) non mutata (SOUNDTRACK-C1)

5 ottobre 2026 aggiornato da: AstraZeneca

Studio di Fase III, Randomizzato, in Aperto, Multicentrico, su Surovatamig come Terapia di Consolidamento rispetto all'Osservazione dopo Terapia di Induzione di Prima Linea in Partecipanti con Leucemia Linfatica Cronica o Linfoma Linfocitico a Piccole Cellule con IGHV Non Mutato (SOUNDTRACK-C1)

The purpose of this study is to evaluate the therapeutic benefit and safety of subcutaneous (SC) Surovatamig monotherapy as consolidation therapy in patients with Chronic Lymphocytic Leukaemia (CLL)/ Small Lymphocytic Lymphoma (SLL) with unmutated IGHV (uIGHV).

Descrizione dettagliata

This is a Phase III global, randomised, open-label, multicentre study. The study will consist of 2 sequential parts- the Dose Optimisation and Safety Run-in part and the Phase-III part.

During the dose optimisation and safety run-in part, Surovatamig will be initiated in 2 dose levels. This part will help to determine the recommended phase III dose (RP3D) of Surovatamig to be used in Phase III part. Phase III would comprise of 2 arms, Arm A where the Surovatamig dose (RP3D) will be administered as a consolidation therapy (post standard of care [SOC] induction therapy) and Arm B where participants will be observed. In Phase 3 participants will be randomized in a 1:1 ratio to Arm A or Arm B.
