> Steroids do dampen T-cell activity, but to what degree that impacts CAR-T effectiveness is not clear.

It's an interesting question. Tangential, but in the early days of discussing how to incorporate anti-PD1s into different treatments, there was lots of concern about the negative effects of steroids --let alone chemo-- on T-cell function. Yet a few years later, aPD1 + chemo is well established in lots of settings.

And likewise, despite data from mouse models that steroids and chemo do impair T-cell function, we're now seeing CAR-Ts and also CD3-engaging bispecific Abs combined directly with chemo - again, with good efficacy.
