> A total of 15 participants received CTX310 and had at least 60 days of follow-up. No dose-limiting toxic effects related to CTX310 occurred. Serious adverse events occurred in two participants (13%): one participant had a spinal disk herniation, and the other died suddenly 179 days after treatment with the 0.1-mg-per-kilogram dose.

Two out of 15 having adverse advents seems pretty high, especially since one died. The supplemental material rules this as an unrelated death (https://www.nejm.org/doi/suppl/10.1056/NEJMoa2511778/suppl_f...).
Definitely seems promising for a larger-scale trial, but it seems weird to make such a strong conclusion about adverse reactions.
