#ASH21 Oral abstract:Ciltacabtagene Autoleucel for Triple-Class Exposed MM:Adjusted Comparisons of CARTITUDE-1 Patient Outcomes Versus Therapies from Real-World Clinical Practice from the LocoMMotion Prospective Study #mmsm 🧵

🛑some important issues👇
#ASH21#mmsm
➡️Cilta Cel is effective in difficult to ttt pts, this is not the aim of the discussion
➡️In this abstract,authors compared a prospectively matched triple class ref MM pts who received diff ttt vs Cilta cel
➡️ what did they find? 👇 (Cilta Cel better) but wait🛑
➡️Read results 👇
1️⃣countries:only 9% RWCP in US vs. 100% of pts who got Cilta Cel in CARTITUDE-1 were in US (16 Center) ➡️study compared pts across the ocean with diff access to ttt🙈
2️⃣>90 ttt options😅
3️⃣2 of the most frequently used regimens were doublet 🙈Kd (~14%),Pd (11%)
Is it fair to compare “prospectively matched” R/R MM pts with doublet vs. CAR-T across diff countries with diff access to diff therapies?! 🤷♂️
At least does in the US: patient with excellent ECOG, organ function , etc (CAR-T candidate) will def receive a better regimen 😅
Few Qs to ask authors at presentation
❓percentage of pts in RW with ASCT (baseline)+who received salvage ASCT?
❓percentage of pts in RW who received triple/Quad+newer agents (bispecific)
❓ sequencing of ttt+details of >90 therapies ,it is imp to see what you are comparing to
➡️While Cilta Cel is effective(no doubt),IMO this comparison is NOT fair and the results are NOT informative
➡️ appropriate RCT comparison with appropriate control for similar pts/access is the way to go

➡️ VOD (~15% ,all types): a bad complication with high mortality (severe type, historically >80%)
➡️ Diagnosis &grading(see tables👇) (nature.com/articles/bmt20…)
➡️Authors question: is defibrotide cost-effective using price input from Spain (note this is likely different from US)
➡️ Simplified definitions:
1⃣ Cost-effectiveness analysis(CEA) is usually measured by incremental cost-effectiveness ratio (ICER) and it establishes how much extra has to be paid for extra benefit.
Summary of cytoplasm/nucleus changes in leukocytes:
1️⃣ Hyposegmentation of neutrophils(peanut shaped, bilobed,or non-segmented nucleus with coarse chromatin)
🔬associations: Pelger–Huët anomaly(inherited) or pseudo-Pelger–Huët anomaly(acquired)
➡️Pelger–Huët anomaly(inherited):affect majority of granulocytes: autosomal dominant- mutations in the lamin B receptor gene
➡️Pseudo-Pelger–Huët anomaly(acquired): <50% of granulocytes: usually occurs with other morphological changes of malignancy: can see in MPNs or MDS #Heme
2️⃣Hypersegmentation of neutrophils
➡️≥ 6 lobes in granulocyte nucleus
🔬associations: megaloblastic anemia, chronic infections, MDS, familial(rare) #Heme
