My Kappa: Lambda Ratio has been slowly increasing over the past year. Now at 1.82 (ref range 0.26-1.65). My Oncologist suggested maybe making a change. The listed risks and protocol sure doesn’t sound very inviting.

Members discussed transitioning to Tecvayli (Teclistamab) after Revlimid appeared to lose effectiveness, with one member who had undergone CAR-T therapy describing Teclistamab as essentially CAR-T in a box and expressing confidence in its safety when properly monitored, despite risks like cytokine release syndrome. Several members acknowledged the intimidating initial dosing protocol requiring a 48-hour hospital stay, with the original poster sharing understandable hesitation given memories of a 40-day ASCT hospitalization, though they remained open to considering it. A recurring theme was gratitude for the community as a safe space to process complex treatment decisions with others who truly understand the journey, alongside practical considerations like medication availability in different countries and the value of having time to weigh options carefully.

Steve, I am always so happy that we have this group to bounce ideas off ... someone from the same tribe, who might appreciate what's going through the mind of one of our group. To generously share their experience is a gift to someone thirsty for such specific information. Mike

To be fair, I had little choice in the matter… Nevertheless, with proper care and monitoring, I wouldn’t be especially worried about Teclistamab. It’s essentially CAR-T in a box. Are there risks of severe CRS/ICANS? Sure, but manageable in the right environment. Sounds like you’ve have time to think it through, so that’s a plus. One other thing, I was youngish (52) and pretty healthy other than the heart failure (IIIa disease).

I had CAR-T (Cilta-cel) in 12/23. I was in the hospital for 15 days in an over-abundance of caution due to cardiac concerns. CRS was Grade 1 and lasted about a day. Easily managed with Tocilizumab. When remission ends, I’ll probably lobby for a transplant, but failing that, I’d have zero qualms about Teclistamab. Bear in mind, I’m in NYC, and can walk to Sloan Kettering on a good day…

Steve,
Sorry to hear your Kappa: Lambda ratio has been slowly increasing. I can't comment as I take nothing other than Gabapentin for peripheral neuropathy. Keep us updated with your changes. Mike
