Yes: test articles were surrogates - murine BB305-transduced thalassaemic BM cells or human healthy-donor HSCs in NSG mice
“the test articles used during non-clinical studies were surrogates, and consisted of either thalassaemic mouse bone marrow cells transduced with BB305 LVV”
Mouse only: β-thalassemic (primary transplant) and wild-type C57BL/6 (secondary transplant) mice given transduced murine BMCs
“In vivo pharmacology and toxicology studies were conducted to evaluate the activity and safety of BB305 LVV-transduced murine BM cells (BMCs) following primary and secondary transplantation in β-thalassemic and wild-type C57BL/6 mice, respectively.”

Surrogate used in
Yes: BB305-transduced thalassaemic mouse BM cells in Hbbth1/th1 mice and healthy-donor human HSCs in NSG mice
“the test articles used during non-clinical studies were surrogates, and consisted of either thalassaemic mouse bone marrow cells transduced with BB305 LVV, or human healthy donor HSCs transduced with BB305 LVV, administered to β-thalassaemic (Hbbth1/th1) mice and immunodeficient NOD scid gamma (NSG) mice, respectively.”
