Bispecific antibodies are showing unprecedented single agent activity in relapsed/refractory MM. There are several phase I trials in this setting, let’s see at the data shared at #ASCO22 and #EHA2022 with Teclistamab , Elranatamab and REGN5458 targeting BCMA and…

Talquetamab SC combined with Daratumumab SC across two doses with weekly/q2 weekly dosing schedules, shows a response rate 76.5%, MRD- 27% at 10-5 via NGS, CRS ~65% (grade 1/2), dysgeusia 57%, median follow-up 4 months library.ehaweb.org/eha/2022/eha20…#CARTSM#MedIQ22ASCO#EHA2022
1/For this #ASH21 'Best of Abstracts' selection, I asked my @sloan_kettering#mmsm service team members for top 5 abstracts in different categories. Please follow the thread below for the #ASH21_MSKMM selections:
The chromosome 1q21 story (1/10):
-Having extra copies of generally odd num. chromosomes constituents hyperdiploidy #mmsm , recognized as ‘HY’ in GEP based molecular classification.
-Having 3 copies is called ‘gain 1q21’
-Having >=4 copies is called ‘amplification of 1q21’.
The chromosome 1q21 story (2/10):
-Herve Avet-Louiseau identifies 1q21 ‘enhancement’ in human MM cell lines, primary MM cells and plasma cell leukemia (PMID: 9172003), Shaughnessy et al corroborate (PMID: 15472896).
- Gain/Amp ch. 1q21 first recognized as poor prognostic markers
The chromosome 1q21 story (3/10):
...in MM by Arkansas group in mid-2000s (PMID: 16188652, PMID: 16705089)
- Corroborated by other groups (PMID: 16995883, PMID: 17024118, PMID: 20537706, PMID: 21523726) in the context of pre-novel and doublet novel induction/transplant era.
