betibeglogene autotemcel · HBB T87Q (LVV, ex vivo HSC)
Longest pivotal study
26 weeks
“Findings observed in the animals that survived to the Month 6 scheduled sacrifice included the following:”
✓ VerifiedFDA pharmacology/toxicology review, p. 18Source ↗
Pivotal GLP studies
Combined pivotal POC/biodistribution/single-dose tox/genotox studies in thalassaemic mice (primary and secondary transplant), NSG mice; single IV dose after busulfan
“These in vivo studies (NC-11-002, NC-12-019, B2-15-161 and B2-16-200) were pivotal and combined pharmacology, biodistribution, single-dose toxicity and genotoxicity studies”
