Surovatamig som konsolideringsterapi hos deltagere med kronisk lymfatisk leukæmi eller småcellet lymfocytisk lymfom med umuteret immunoglobulin heavy chain variable (IGHV) (SOUNDTRACK-C1)

5. oktober 2026 opdateret af: AstraZeneca

En fase III, randomiseret, åben-etiket, multicentrisk undersøgelse af Surovatamig som konsolideringsterapi versus observation efter førstelinjes induktionsterapi hos deltagere med kronisk lymfatisk leukæmi eller lille lymfocytisk lymfom med umuteret IGHV (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).

Detaljeret beskrivelse

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.
