Imp. paper by @VincentRK ๐๐ก ๐๐ on mode of progression in a ๐ฆ๐จ๐๐๐ซ๐ง ๐๐จ๐ก๐จ๐ซ๐ญ of patients with smoldering #myeloma!
Helpful for initial discussion in patients with ๐๐ข๐ ๐ก-๐๐ข๐ฌ๐ค ๐๐๐ re. clinical trials vs active surveillance vs Len
๐finding: 23/71 pts. (~๐๐%) with HR-SMM progressed to clinically significant MDEs (Bone Disease/Hypercalcemia/Renal Failure) at a median f/u of ~4 years!
In other words, >2/3rd of patients with HR-SMM did ๐ง๐จ๐ญ have clinically significant MDEs at progression!
2/4
What about all MDEs (CRAB)?
At a median follow-up of ~4 years, 39/71 patients (~๐๐%) with HR-SMM on active surveillance progressed to CRAB! This is ๐ฌ๐ฎ๐๐ฌ๐ญ๐๐ง๐ญ๐ข๐๐ฅ๐ฅ๐ฒ ๐ฅ๐จ๐ฐ๐๐ซ than 2-year risk of ~50% in pts with HR-SMM, as we quote using 20/2/20!
3/4
Imp.โ: What % of pts had baseline ๐๐ ๐๐-๐๐๐, the most sensitive imaging modality to r/o myeloma? Its plausible that with WB DW-MRI, fewer bone lesions may be expected as MDEs!
Grateful to the ๐๐พdatabase @MayoMyeloma that has taught us so much about this disease!
4/4
Curious to hear thoughts from SMM aficionados @EliasKarlMai @ManniMD1 @arjunlakshmanMD @SusanBal9 @MeeraMohanMD @AaronGoodman33 @MalinHultcrantz @Amyloid_Planet

Our study on outcomes with Dara-VCD in AL #Amyloidosis outside of clinical trials: What did we learn beyond ANDROMEDA?
@columbiacancer @CAMPamyloidosis
@SLentzsch @MurielFinkel @MathewMaurer @DivayaB
1. Hopefully, the days are gone when ~30% of pts with stage IIIa and ~60-70% of stage IIIb would unfortunately die by 1 year! We show that early mortality has โฌ๏ธed (can't explain solely by early diagnosis since >65% of our cohort were stage IIIa/b and median NT-proBNP of ~3300)
2. Despite a sicker population than ANDROMEDA and a higher clone burden in bone marrow, hematologic & organ responses comparable (or even superior)!
The prevailing dogma regarding salvage ASCT in #Myeloma is to offer to pts who had prolonged remission after ASCT1 (typically >3 yrs).
The assumption is that a long remission after ASCT1 would ๐ฉ๐ซ๐๐๐ข๐๐ญ forโฌ๏ธbenefit from ASCT2 over std therapies!
Enter ReLapse Trial!
What was the design?
โ 1:1 randomization to Rd re-inductionโก๏ธASCTโก๏ธR maint. vs Rd continuous until PD
โ R-refractory not allowed (only 11% R-exposed)
โ Only pts with time to PDโฅ12 mo. from ASCT1 allowed!
Few thoughts on CANOVA trial (Ven-Dex vs Pom-Dex in t[11;14]). I do think that venetoclax still has a role in t(11;14) plasma cell disorders, but these results add nuance to my interpretation of venetoclax data and how I will use it.
First, PFS numerically higher with Ven but not statistically significant is disappointing!
But one thing to note here is the differential censoring (something I have learnt from @VPrasadMDMPH to always pay attention to in PFS curves):
7% (Ven) vs 20% (Pom) at 10 mo.
We can only speculate as to why, but from the TTNT curves, it seems to be because more patients in Pom-Dex arm switched to a subsequent line of therapy without progression! Perhaps due to suboptimal response?
With high-risk #MultipleMyeloma being a challenging entity to manage despite new drugs, the ๐๐๐๐-๐๐๐๐๐๐๐ ๐ฌ๐ญ๐ฎ๐๐ฒ #IMS23 @JCO_ASCO is an imp. addition! ๐งตon the key takeaways and what can we learn (with focus on ASCT-Eligible pts) tinyurl.com/2rumue4e
First, lets look at the regimen for transplant-eligible pts:
Isa-KRD x 6 โก๏ธAuto-Transplant (90% single auto) โก๏ธIsa-KRD x 4 โก๏ธIsa-KR x โ2 years
๐๐ฝfor allowing 1 cycle of therapy prior to enrollment & oligo-/non-secretory disease!
Second, how was "high-risk" defined for inclusion in this trial?
ISS II/III
๐๐๐
1 or more of: t(4;14), t(14;16), del(17p), or amp(1q)
Approx. 1/3rd of pts were double/triple-hit (โฅ2 high-risk abnormalities)!

We commonly get consulted by other specialties when M-protein or increased serum FLC ratio is discovered during workup of kidney injury.
This table provides a great framework on how to approach these situations!
In such situations, I look for two critical pieces of info:
โ How high is the involved FLC (iFLC)?
โ What does 24-hour UPEP/IFE show? Predominantly albuminuria or BJ proteinuria or mixed?
1. Drugs with high symptomatic toxicities are ๐๐๐ good for maintenance therapy. IMO, drugs like selinexor and belantamab mafadotin are perhaps in the same league and unlikely to be successful in maintenance setting. 2x greater risk of Rx discontinuation in Vorinostat arm!!
2. Great to see that number of patients ๐๐๐ง๐ฌ๐จ๐ซ๐๐ at each time point provided in K/M curve! PFS, as an endpoint, is prone to differential censoring. Given higher symptomatic toxicity, I would be concerned aboutโฌ๏ธcensoring in VR arm, but there wasn't.
