No immunosuppression in 28-day rat KLH antibody response study
“Twice daily oral administration of mavorixafor for up to 250 mg/kg/day for 28 consecutive days to Sprague-Dawley rats did not result in immunosuppression.”
Rat QWBA: persistent binding to melanin-containing uveal tract up to 840 h
“In partially pigmented rats, measurable radioactivity was observed in the uveal tract/whole eye from 8 hours until the final sampling time of 840 hours, suggesting irreversible binding to melanin-containing tissues.”
Hepatotoxicity, embryofetal risk, male fertility impairment, QTc prolongation and retinal damage
“The primary safety concerns associated with mavorixafor in animals were liver, embryo-fetal developmental risk, impairment of male fertility, potential for corrected QT interval (QTc) prolongation, and retinal damage.”
