Surovatamig som konsolideringsterapi hos deltagare med kronisk lymfatisk leukemi eller småcelligt lymfocytärt lymfom med omuterad immunoglobulintung kedjevariabel (IGHV) (SOUNDTRACK-C1)

5 oktober 2026 uppdaterad av: AstraZeneca

En fas III, randomiserad, öppen, multimetrisk studie av Surovatamig som konsolideringsterapi jämfört med observation efter första linjens induktionsterapi hos deltagare med kronisk lymfatisk leukemi eller småcellig lymfocytlymfom med omuterad 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).

Studieöversikt

Detaljerad beskrivning

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.
