To assess the safety and tolerability of SC surovatamig as consolidation therapy using dose optimisation in CLL/SLL participants with uIGHV. Also, to determine the RP3D of SC surovatamig monotherapy as consolidation therapy in CLL/SLL participants with uIGHV.
PFS is defined as the time from date of randomisation until disease progression or death due to any cause, whichever occur first based on International Workshop on Chronic Lymphocytic Leukemia (iwCLL) 2018 criteria, as assessed by independent review committee (IRC).
To assess the safety and tolerability of SC surovatamig as consolidation therapy using dose optimisation in CLL/SLL participants with uIGHV. Also, to determine the RP3D of SC surovatamig monotherapy as consolidation therapy in CLL/SLL participants with uIGHV.

The RP3D will be the dose of Surovatamig selected for the Phase 3 part based on safety data compiled during the safety run-in part
PFS, based on Lugano 2014 Response Criteria, as assessed by BICR.
To assess the safety and tolerability of surovatamig on adverse events, including Adverse events, Serious adverse events, Adverse event of special interests, and Adverse events leading to discontinuation of surovatamig.
To assess the effect of surovatamig on proteinuria
