Minimal TDAR effects in 39-week dog study: reduced IgM/IgG titers to KLH
“T-Dependent Antibody Response (TDAR) assay conducted with blood from dogs in 39-week toxicology study presented minimal effects on the humoral responses with reduced IgM and/or IgG titers following primary response to KLH challenge in both genders.”
Detected in melanin-containing eye tissues up to 168 h, suggesting ocular melanin affinity
“In pigmented animals, iptacopan was detected in melanin containing eye tissues (choroid and ciliary body) up to 168 hrs which suggests affinity to ocular melanin.”
Infection risk; also heart, thyroid and male reproductive organ effects
“A primary concern identified early in product development was a signal for infection. Other systems/organs affected by iptacopan were the heart (dog, monkey), thyroid (rat, dog), and male reproductive organs (rat, dog).”
