Just a quick update: Oliver’s CAR T cells have officially been detected in his blood. We are expecting them to keep growing and expanding over the coming weeks. He continues to feel well with no real side effects or toxicity. And we are still out-patient, which is a big blessing!

Next week we will check for the CAR T cells again to make sure they’ve expanded. We won’t know whether they’re successful from a cancer standpoint until we have a biopsy 28 days from the infusion day (May 5).
