However, we must balance the risk of persistent immunosuppression with teclistamab and its efficacy.

In the MajesTEC-1 study,...

I reviewed the investigator brochure for all the FDA-approved bispecific antibodies, and saw very little pharmacokinetic (PK) or pharmacodynamic (PD) data.

Hence, for patients that achieve a ≥VGPR after 1 month of weekly treatment, it's appealing to switch to monthly dosing for BCMA-directed bispec...

We have started to de-escalate quickly, particularly for our elderly patients, who are having more difficulty tolerating teclistamab. Once the patients achieve at least a PR (which seems to be apparent within 2 cycles), we have been moving to q 2 weeks and even monthly, with what appears to be bette...
