Higher ORR and CR rate in less heavily pretreated patients suggest that this regimen, as an earlier treatment, may improve outcomes. buff.ly/bi4dpzR #hemesky #clinicaltrialsandobservations

I usually refrain from sharing political views on these platforms, as I prefer to focus on scientific advancements. However, today I see it as an educational opportunity. I’m not sure everyone south of the border fully realizes the impact this is having and will continue to have for years to come.

Hyperferritinemia syndromes following CD19 CAR T cells for Lymphoma
- Hyperferritinemia (HF) = inferior survival.
- HF = greater toxicity.
- HLH-like manifestations in 28% of patients.
- Impact of HF independent of CRS, ICANS, and tumor burden.

Nice work by one of our @mskcancercenter.bsky.social BMT fellows Moataz Ellithi on Neurotoxicity and Rare Adverse Events in BCMA-Directed #CARTCells: Real-World FAERS Data - Now out in @astct.bsky.social journal #mmsm www.astctjournal.org/article/S266...

Excellent presentation by Dr. Sehn on Tafa-R2 in relapsed/refractory follicular lymphoma at #ASH2024. InMIND: ''adding tafasitamab to R2 resulted in a 57% reduction in the risk of progression, relapse, or death''.

Liso-Cel Shows Broad Spectrum Activity in CIBMTR Cohort of Relapsed/Refractory LBCL Liso-cel demonstrated safety and efficacy outcomes that were comparable to those in the pivotal TRANSFORM and PILOT trials in patients with relapsed/refractory large B-cell lymphoma.

Overall response rate (ORR) of 100%! Now with long term data showing 5-yr-Progression Free Survival (PFS) of 91%.

Neither Pembro nor GVD alone is as efficacious, begging the mechanistic question of “synergy” - that is, how do immunotherapy and chemotherapy combine to become more than either alone?

Real-world comparison of CD19 CAR T cells for LBCL.
- 501 patients from 4 centers.
- Inferior outcomes with tisa-cel.
- Higher ORR and CR rates with liso-cel.
- Liso-cel and axi-cel = similar PFS and OS rates.
- Less toxicities with liso-cell.

Come and check out @mskcancercenter.bsky.social Kai Rejeski's talk on #CARTcells toxicity #ASH24
👉 In CAR-TOGRAPHY we graded >32,500 pt days across 4 sites in 902 CAR-T recipients, yielding >125,000 unique toxicity datapoints.
👉 Develop new metrics to describe early toxicity: CTI & tox phenotypes

Point-of-care vs commercial CD19 CAR-T therapies.
- Median vein-to-vein time: POC=11d, axi-cel=38d, tisa-cel=44d.
- Grade 2+ CRS: POC=26%, axi-cel=52%, tisa-cel=37%.
- Comparable survival outcomes.

! Hot off the press !
Excited to share this interesting case of long-term axi-cel persistence and to brainstorm about the role of immune checkpoint inhibitors in CAR T-cell therapies.
