Brief summary: This is a randomized, 2-arm phase II, multi-center study to evaluate the overall response rate in newly diagnosed, transplant ineligible patients receiving 9 cycles induction therapy with either KTd or KRd followed by randomization to either carfilzomib maintenance treatment for 12 months or to observation only. Maintenance is given for 12 cycles or progression of disease, whatever occurs first.

Detailed description: Multiple myeloma, a clonal neoplastic proliferation of plasma cells, is the second most common hematologic malignancy and accounts for approximately 72,000 annual deaths worldwide. There are an estimated 11,000 deaths per year in the US and more than 19,000 deaths per year in Europe.

This study examines the efficacy of carfilzomib (K) in combination with thalidomide, an old, well established first line immunomodulatory imide drugs (IMiD) in newly diagnosed multiple myeloma versus K in combination with lenalidomide in 1st line. This trial will also evaluate the adherence to and the safety of a thalidomide containing triplet by using a non-neurotoxic proteasome inhibitor. Moreover, weekly dosing of carfilzomib addresses the need for a more convenient dosing schedule. Finally, yet importantly, this trial will assess the efficacy of a less cost intensive triplet and a strategy to keep lenalidomide as backup for later lines.. The second part of the study - after completing 9 cycles induction therapy with KTd or KRd - patients of both arms will be pooled and again randomized 1:1 stratified by induction therapy into two arms (K-monotherapy versus observation-only).

Eligibility criteria: Inclusion Criteria:

* Able to provide written informed consent in accordance with federal, local, and institutional guidelines
* newly diagnosed, symptomatic multiple myeloma
* Transplant-ineligibility: age \> 65 years or patients not eligible due to comorbidities determined by investigator or patients not willing to undergo autologous stem-cell transplantation (ASCT) on personal preference
* Measurable disease, as defined by one or more of the following (assessed within 21 days prior to randomization):

  * Serum M-protein ≥ 0.5 g/dL, or
  * Urine M-protein ≥ 200 mg/24 hours, or
  * In subjects without detectable serum or urine M-protein, serum-free light chain (SFLC) \> 100 mg/L (involved light chain) and an abnormal κ/λ ratio
* No prior treatment for multiple myeloma
* Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0-1
* Patients at cardiac risk (NYHA \>II or pre-existing coronary heart disease or any other relevant cardiac complication) should be scheduled for a baseline echocardiography (ECHO) and can only be included if the left ventricular ejection fraction (LVEF) is ≥40%); independent of cardiac risk ECG has to be done for inclusion of Asian patients and patients \> 75 years of age
* Adequate organ and bone marrow function within the 21 days prior to randomization defined by:

  * Bilirubin \< 2 times the upper limit of normal (ULN), Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) \< 3 times the ULN
  * growth factor support for max 3 days allowed to achieve an absolute neutrophil count (ANC) ≥ 1000/mm3 (screening ANC should be of required)
  * Hemoglobin ≥ 7.0 g/dL; use of erythropoietic stimulating factors and red blood cell (RBC) transfusion per institutional guidelines is allowed, however the most recent RBC transfusion may not have been done within 7 days prior to obtaining screening hemoglobin.
  * Platelet count ≥ 30,000/mm3
* Calculated or measured creatinine clearance (CrCl) of ≥ 30 mL/min. Calculation should be based on the Cockcroft and Gault formula: \[(140 - Age) ∙ Mass (kg) / (72 ∙ Creatinine mg/dL)\]; multiply result by 0.85 if female
* Females of childbearing potential (FCBP) must have a confirmed negative serum pregnancy test within the 21 days prior to randomization (performed at a central laboratory).
* Females of childbearing potential and male subjects who are sexually active with FCBP must agree to use effective concomitant method(s) of contraception during the study and for 30 days (women) and 90 days (men) following the last study drug treatment administration.
