Drugs: KZR-616 Research and Development Enterprise: Kezar Life Sciences Treatment Of Diseases: Dermatomyositis (DM);
preclinical studies have shown that selective immunoprotease inhibition produces a wide range of anti-inflammatory reactions in animal models of a variety of autoimmune diseases, while avoiding immunosuppression.
early clinical results of KZR-616 have the potential for long-term treatment of severe, chronic autoimmune diseases and immuno-mediated diseases.
the drug is in Phase 2 clinical trials of lupus nephritis and dermatitis/multiple myocarditis, according to the company's website.
drugs: ACN00177 Research and Development Enterprise: Aeglea Biotherapeutics Treatment of Diseases: Homocystinuria Introduction: Homocysteinuria: Homocysteinuria is a rare disease caused by genetic defects of cysthione β sysyme.
most common medical diseases associated with typical high cysteine uremia are cardiovascular complications, including an increased risk of blood clots.
other symptoms include bone abnormalities, eye crystal dislocation, developmental and learning defects.
currently available classic homocysteine uremia treatments include high doses of vitamin B6 and beetline (N, N, N,N-methyl glycine) to reduce homocysteine levels.
these treatments are effective in some patients, the response is significantly different because of the genetic mutations that drive the disease.
ACN00177 is a homocysteine enzyme that is expected to degrade homocysteine and oxidized homocysteine in the blood.
reduction in homocysteine/high cysteine levels may prevent or slow the progression of the disease in these patients.
