Exclusion criteria

Exclusion criteria: - Evidence of any of the following calcium, renal failure, anemia, bone lesions (CRAB) criteria or Myeloma Defining Events (SLiM CRAB) detailed below (attributable to the participants SMM involvement): *Increased calcium levels: Corrected serum calcium >1 mg/dL above the ULN or >11 mg/dL *Renal insufficiency: Determined by glomerular filtration rate (GFR) 2 mg/dL *Anemia (hemoglobin 2 g/dL below lower limit of normal or <10 g/dL or both) transfusion support or concurrent treatment with erythropoietin stimulating agents is not permitted *= 1 bone lytic lesion = 5mm in size *BMPCs =60% *Serum involved/uninvolved FLC ratio =100 and an involved FLC = 100mg/L *Whole body magnetic resonance imaging (WB-MRI) or positron emission tomography-computed tomography (PET-CT) with more than 1 bone focal lesion (=5 mm in diameter by MRI) - Primary systemic and localized amyloid light-chain (AL) amyloidosis, monoclonal gammopathy of undetermined significance (MGUS), standard risk smoldering myeloma, soft-tissue plasmacytoma, and symptomatic myeloma - Uncontrolled infection within 28 days prior to randomization in Phase 3 or first study intervention administration in safety run-in - Clinically significant cardiac or vascular disease within 3 months prior to randomization, e.g. Myocardial Infarction; Unstable Angina; Coronary (e.g. Coronary Artery Bypass Graft, Percutaneous Coronary Intervention) or peripheral artery revascularization, Left Ventricular Ejection Fraction <40%, Heart Failure NYHA III-IV, Stroke, Transient Ischemic Attack, Pulmonary Embolism, other thromboembolic event, cardiac arrhythmia (Grade 3 or higher by NCI-CTCAE Version 5.0) - Known acquired immunodeficiency syndrome (AIDS)-related illness or known human immunodeficiency virus (HIV) disease requiring antiviral treatment or active hepatitis A (defined as positive hepatitis A antigen or positive IgM). HIV serology at screening will be tested for German participants and any other country where required as per local regulations and serology hepatitis B and C at screening will be tested for all participants. -Uncontrolled or active HBV infection: Patients with positive HBsAg and/or HBV DNA Of note: · Patient can be eligible if anti-HBc IgG positive (with or without positive anti-HBs) but HBsAg and HBV DNA are negative. If anti-HBV therapy in relation with prior infection was started before initiation of IMP, the anti-HBV therapy and monitoring should continue throughout the study treatment period. · Patients with negative HBsAg and positive HBV DNA observed during screening period will be evaluated by a specialist for start of anti-viral treatment: study treatment could be proposed if HBV DNA becomes negative and all the other study criteria are still met. - Active HCV infection: positive HCV RNA and negative anti-HCV Of note: - Patients with antiviral therapy for HCV started before initiation of IMP and positive HCV antibodies are eligible. The antiviral therapy for HCV should continue throughout the treatment period until seroconversion. - Patients with positive anti-HCV and undetectable HCV RNA without antiviral therapy for HCV are eligible - Malabsorption syndrome or any condition that can significantly impact the absorption of lenalidomide - Any of the following within 3 months prior to randomization (or first study intervention administration in safety run-in cohort): treatment resistan
