Surovatamig as Consolidation Therapy in Participants With Chronic Lymphocytic Leukaemia or Small Lymphocytic Lymphoma With Unmutated Immunoglobulin Heavy Chain Variable (IGHV)

Summary

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).

* ECOG performance status of 0 to 2.
* Adequate haematologic, liver, renal and cardiac function.
* Female participants: must be either women not of childbearing potential or must use a highly effective form of contraception.
* Male participants who intend to be sexually active with females of childbearing potential must agree to use barrier contraception (eg, condoms).

Exclusion Criteria:
