👥Biography 个人简介
Shaji K. Kumar, MD is Professor of Medicine and Consultant in the Division of Hematology at Mayo Clinic, Rochester, where he also chairs the Myeloma, Amyloidosis, and Dysproteinemia Group. He is one of the leading myeloma clinical researchers in North America, known for the CANDOR trial and for his broad contributions to carfilzomib clinical development, myeloma risk stratification, and smoldering myeloma natural history research. Dr. Kumar was a co-lead investigator on the CANDOR trial (Lancet 2020), a phase III study demonstrating that carfilzomib, daratumumab, and dexamethasone (KDd) significantly improved PFS compared with carfilzomib-dexamethasone (Kd) in relapsed/refractory myeloma, leading to FDA approval of the triplet. He is the principal architect of the mSMART (Mayo Stratification for Myeloma And Risk-adapted Therapy) guidelines — the most widely used risk-stratification algorithm in myeloma in North America — which incorporates cytogenetic, LDH, and clinical parameters to guide treatment intensity decisions. Dr. Kumar has also led seminal epidemiological studies at the Mayo Clinic defining the natural history, progression rates, and biomarkers of smoldering multiple myeloma. He has published over 600 peer-reviewed manuscripts and serves as an Associate Editor of Blood and Leukemia journals.
🧪Research Fields 研究领域
🎓Key Contributions 主要贡献
CANDOR Trial — KDd Triplet in Relapsed/Refractory Myeloma
Co-led the phase III CANDOR trial (Lancet 2020; n=466) demonstrating that carfilzomib, daratumumab, dexamethasone (KDd) significantly improved PFS (median not reached vs. 15.8 months; HR 0.63) and response depth versus carfilzomib-dexamethasone (Kd) in relapsed/refractory myeloma after 1–3 prior lines — leading to FDA approval of KDd and establishing daratumumab-carfilzomib as a valid proteasome inhibitor-antibody triplet backbone.
mSMART Risk-Stratification Framework
Developed and iteratively updated the mSMART (Mayo Stratification for Myeloma And Risk-adapted Therapy) guidelines at Mayo Clinic, providing a practical, clinically implementable framework for classifying patients as standard, intermediate, or high risk based on FISH cytogenetics, LDH, and plasma cell labeling index — guiding treatment intensity and enrollment in risk-adapted clinical trials for tens of thousands of patients globally.
Smoldering Myeloma Natural History and Biomarker Research
Led multiple Mayo Clinic population-based cohort studies characterizing the natural history, progression rates (~10%/year in the first 5 years), and clinical/biomarker predictors of progression from smoldering to active myeloma, providing the epidemiological foundation for IMWG risk models and informing ongoing clinical trials of early intervention in high-risk smoldering disease.
Carfilzomib Combination Development and Real-World Evidence
Participated in or led multiple carfilzomib phase I/II/III trials beyond CANDOR — including ENDURANCE (KRd vs. VRd frontline), contributing critical data on the relative positioning of carfilzomib vs. bortezomib in the frontline setting, and has generated extensive real-world outcome analyses from Mayo's large patient registry defining treatment patterns and outcomes in clinical practice.

Carfilzomib or bortezomib in combination with lenalidomide and dexamethasone in patients with newly diagnosed multiple myeloma (ENDURANCE)
The Lancet Oncology (2020)
Phase III ENDURANCE trial comparing KRd vs. VRd in non-transplant NDMM, demonstrating equivalent PFS and establishing VRd as the standard non-transplant frontline backbone.
Carfilzomib, dexamethasone, and daratumumab versus carfilzomib and dexamethasone in relapsed or refractory multiple myeloma (CANDOR)
The Lancet (2020)
Phase III CANDOR trial establishing KDd triplet superiority over Kd doublet in relapsed/refractory myeloma, leading to FDA approval.
Natural history of smoldering multiple myeloma
Blood (2010)
Landmark Mayo Clinic cohort study characterizing progression rates and risk factors for smoldering myeloma transformation, foundational to current IMWG risk models.
Mayo Stratification of Myeloma and Risk-Adapted Therapy (mSMART) Consensus Guidelines 2018 Update
