Prednisolone reduces the interferon response to AAV in cynomolgus macaques and may increase liver gene expression.

ABSTRACT: Ornithine transcarbamylase deficiency is a rare X-linked genetic urea cycle disorder leading to episodes of acute hyperammonemia, adverse cognitive and neurological effects, hospitalizations, and in some cases death. DTX301, a non-replicating, recombinant self-complimentary adeno-associated virus vector serotype 8 (scAAV8)-encoding human ornithine transcarbamylase, is a promising gene therapy for ornithine transcarbamylase deficiency; however, the impact of sex and prophylactic immunosuppression on ornithine transcarbamylase gene therapy outcomes is not well characterized. This study sought to describe the impact of sex and immunosuppression in adult, sexually mature female and male cynomolgus macaques through day 140 after DTX301 administration. Four study groups (n = 3/group) were includ
