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‡๏ธed (can't explain solely by early diagnosis since >65% of our cohort were stage IIIa/b and median NT-proBNP of ~3300) Image

Phase III GMMG ReLApsE Trial #ASH23: Is it the last nail in the coffin of salvage auto-transplant in relapsed #MultipleMyeloma?

Lets unpack in this short ๐Ÿงต (also, an important teaching point on prognostic vs predictive marker!)

tinyurl.com/2s36byjf 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 ๐ฉ๐ซ๐ž๐๐ข๐œ๐ญ forโฌ†๏ธbenefit from ASCT2 over std therapies!

Enter ReLapse Trial!

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. Image

With high-risk #MultipleMyeloma being a challenging entity to manage despite new drugs, the ๐†๐Œ๐Œ๐†-๐‚๐Ž๐๐‚๐„๐๐“ ๐ฌ๐ญ๐ฎ๐๐ฒ #IMS23 @JCO_ASCO is an imp. addition! ๐Ÿงตon 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 โžก๏ธAuto-Transplant (90% single auto) โžก๏ธIsa-KRD x 4 โžก๏ธIsa-KR x โ‰ˆ2 years

๐Ÿ‘๐Ÿฝfor allowing 1 cycle of therapy prior to enrollment & oligo-/non-secretory disease!

This table provides a great framework on how to approach these situations! Image

Although a negative trial, the recently published Vorinostat-Len (VR) vs Len (R) analysis of Myeloma XI RCT had some important learning points๐Ÿงต#mmsm @profghjackson @DrGarethMorgan1
tinyurl.com/ysxu446k 1. Drugs with high symptomatic toxicities are ๐’๐’๐’• 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!!

Ten #ASH20 #MultipleMyeloma abstracts that I think will most inform my clinical practice [๐‘ป๐’‰๐’“๐’†๐’‚๐’…] #1/11 #mmsm 1. Another trial [๐‘ญ๐‘ถ๐‘น๐‘ป๐‘ฌ] shows meaningful PFS benefit with early ASCT [after KRD], irrespective of cytogenetic risk. (Despite similar early MRD-negative rates in both arms) tinyurl.com/y4re2gpw #mmsm 2/11
