⭐️Trials that enrolled at time of transplant (as opposed to time of diagnosis) such as STAMINA may not be able to enroll those with the most aggressive disease who relapse during induction or die from toxicity during induction.
⭐️ There were indeed patients who progressed on the MASTER trial after receiving DKRD>transplant while being off therapy.
Yet, even in GRIFFIN (DRVD>Auto>DR) some patients progressed while on doublet maintenance.
We cant attribute progression to them not being on treatment.
^ This brilliant point shows that doublet maintenance isnt enough to adequately treat the highest risk, and better strategies are needed.
Makes me seriously question doublet maintenance strategy :(
Many other pearls- but youll have to listen to it.
I appreciated the nuance with with the surrogacy question was approached!
Thanks all!

1) We start by describing how myeloma is incredibly heterogenous yet treated in a uniform fashion.
There indeed is ample opportunity to treat myeloma in a personalized fashion based on unique features!
Next, we talk about melflufen.
At a ODAC meeting, the sponsor of melflufen tried to tell us that for elderly patients (who represented a very small subset) of patients on the trial, melflufen was better than pomalidomide.
2) MGUS defined today after exclusion of lytic lesions by advanced imaging and BM biopsy likely has an even lower risk of progression than cohort described by Kyle et al.
As BM biopsy and advanced imaging weren't done routinely in that cohort- some ppl may have had SMM/MM today!
As 2022 wraps up, it is time for a🧵 that highlights 10 pivotal trials that informed my practice and thinking in 2022. These are articles published in 2022 (although initial results/online pub maybe earlier)- abstracts from meetings covered elsewhere.
Despite low cross-over to transplant in non transplant arm upon progression, (and higher MRD neg and PFS in transplant arm), there was no difference in overall survival at 7 yrs of follow-up.
2. MASTER (Sep 2022 (although appeared online in end December 2021- JCO)
Proof of concept that finite intensive therapy with quad and transplant followed by MRD guided discontinuation is feasible. Responses maintained upon updated follow-up.
After ending two weeks on the BMT inpatient service, here is a 🧵 on my favorite BMT CTN trials that I teach to every new fellow/PA/NP/pharmacist/trainee on rounds.
I love these trials, and look forward to the ongoing ones!
1. I will stop using restrictive neutropenic diets for patients who are undergoing transplant
as shown in this non-inferiority randomized trial. Patients are already going through a lot, lets not make it tougher for them by imposing dietary restrictions.
