4. IMWG study on retrospective study of denosumab efficacy and safety in patients with eGFR<30: N=118. 28% of patients discontinued denosumab due to hypocalcemia!! 33.8% had G3 and 6.2% had G4 hypocalcemia. ⬇️baseline calcium levels (p<0.001) and higher denosumab dose (120 vs.

3. LimiTec Trial: Prospective study of Tec discontinuation after 6-9 months of therapy in patients achieving >=VGPR (BMBx/MRD assessment not required): n=43 with 4 prior LoT, 95% TCR, 44% penta-refractory, 23% with prior BCMA-DT. Median f/u ~11 months. Failure-Free Probability

2. iMMagine-1 Phase 2 trial of Anito-cel (@DrKrinaPatel): >=3 prior LoT, 86% triple-class refractory, 40% penta-refractory, ~40% with high-risk cytogenetics. >=CR rate~70% (79/117 patients) MRD-neg rate (10^-5) among evaluable patients (n=75): 93% At median follow-up ~1 year,

1. MAJESTEC-3 [Tec-Dara vs DPd/DVd]: 1-3 prior LoT including a PI and lenalidomide; prior anti-CD38 exposure permitted (refractory not allowed). Topline results: PFS HR 0.17(!!) and OS HR 0.46 favoring Tec-Dara, with 3-year PFS 83% in Tec-Dara arm! MRD-neg rate (10^-5; NGS)

7. SEALAND RCT [Seli-R vs R maintenance post-ASCT, with PFS as primary endpoint]: Negative study, stopped early for futility! Grade >=3 AE 85% in Seli-R vs 45% in R arm My thoughts: In the current landscape, Seli does not belong in earlier treatment lines, especially

4. Unique Trajectory of t(11;14) patients in the context of Quad Induction➡️ASCT ➡️MRD-guided consolidation/maintenance: Significantly lower MRD-negativity rate at all time-points (post-induction MRD-neg rate at 10^-5 only 9% ibn t(11;14)! Significantly longer

3. COBRA Trial [KRd vs VRd RCT in both TI and TE NDMM]: KRd arm: KRd Induction x 12 cycles ➡️KR maintenance x 12 cycles; VRd arm: VRd induction x 8 cycles ➡️Rd maintenance x 16 cycles [Co-primary endpoints: MRD-negative CR at 12 mo. and PFS]. Important to note the hard-wired bias

2. Exceptional outcomes in patients with IMS/IMWG standard-risk disease who achieve sustained MRD-negativity (at 10^-5 at least 12 months apart) in the context of Quad Induction➡️ASCT [88% of these patients were monitored off-therapy after 2 sequential MRD-negative tests]:

We are investigating whether Tec-Dara for fixed duration will improve outcomes in dynamic high risk NDMM. Trial available in Washington, Oregon, Colorado, Utah, Tennessee, Wisconsin, Alabama, New York and Texas (Dallas)
Newly diagnosed with MM? MASTER-2 addressed response adapted therapy with the perspective of finite treatment. Accruing fast! #mmsm

@JoshuaRichterMD @End_myeloma Remarkable results. This will be preferable to CAR T in early line for most patients, especially if we give as a fixed-duration regimen.
