“2) The immunosuppressive action of voxelotor, manifested as increased mortality due to opportunistic infections in monkeys, significantly reduced IgG (rats, monkeys) and IgM (monkeys) titres, delayed antibody response (monkeys)”
Crosses blood-brain barrier at ≥30-fold lower than blood; no melanin binding
“Radioactivity was found to cross the blood brain barrier, but exposure was at least 30-fold lower than in the blood. As pigmented and non-pigmented skin were similarly labelled, it is concluded that there is no melanin binding.”
Compensatory erythropoiesis, immunosuppression and GI toxicity at low safety margins
“The applicant has agreed to include the compensatory erythropoiesis, immunosuppression and adverse gastro-intestinal tract effects action as important non-clinical safety findings in Part II module SII and as identified risks in Part II module SVII of the Risk Management Plan)”
