In this episode, we explore the emerging entity of CAR Transgenic T-cell Lymphoproliferative Neoplasms (CTTLN), a rare but important complication of CAR T-cell therapy. Dr. Piers Blombery from Peter MacCallum Cancer Center joins us to dissect two cases from the CARTITUDE-4 trial where patients developed T-cell lymphomas expressing the chimeric antigen receptor following cilta-cel treatment for multiple myeloma. As a bonus, we also briefly discussed Dr. Blombery’s paper on menin inhibitors in UBTF tandem duplicated AML. Here are the papers we discussed:

1. CTTLN cases from CARTITUDE-4: https://pubmed.ncbi.nlm.nih.gov/39938094/

2. CTTLN case from MSKCC with insertional mutagenesis: https://pubmed.ncbi.nlm.nih.gov/39908432/

3. Other CTTLN cases in myeloma:

4. Response and resistance to menin inhibitors in UBTF tandem duplication AML: https://pubmed.ncbi.nlm.nih.gov/38924737/

I’ve been using Snipd for about a year and this app has been life changing. I listen to about 17 hours of podcasts a week and I want to take notes on 95% of them. Snipd makes it so easy to do. I can triple click my headphones and record a snip. The app also improves rapidly which is welcomed. It’s an easy subscription for me to pay.
