    Alloengraftment without significant toxicity or GVHD in CD45 antibody-drug conjugate conditioned Fanconi anemia mice. (PubMed, Blood)
    Moreover, single dose anti-human CD45-ADC given to rhesus macaque nonhuman primates on days -6 or -10 was at least as myeloablative as lethal irradiation. These data suggest that CD45-ADC can potently promote donor alloengraftment and hematopoiesis without significant toxicity or severe GVHD, as seen with lethal irradiation, providing strong support for clinical trial considerations in highly vulnerable FA patients.

    CD117 Antibody-Drug Conjugate Conditioning Allows Efficient Engraftment of Gene-Modified CD34+ Cells with Fertility Preservation in a Rhesus Gene Therapy Model (ASH 2023)
    To investigate the activity of CD117-ADC in non-human primates, we administered a single injection of ADC without HSC infusion, resulting in a >99% depletion of CD34+CD90+ bone marrow cells in cynomolgus macaques (n=2 of 3 in 0.1 mg/kg and n=3 in 0.3 mg/kg); similar to the ablation observed with 4 doses of myeloablative busulfan (Bu) (n=3). The transplanted animals with ADC maintained their fertility. Overall, these data indicate that an ADC-based targeted approach offers safer conditioning and could improve the risk-benefit profile in HSC gene therapy.
