    Last week the FDA awarded 19 orphan drug qualifications, Kezar Life Sciences' "first-in-class" selective immunoprotease inhibitor KZR-616 qualified for 2 orphan drugs, and Novartis treated Huntington's disease. Small molecule RNA shear regulators for HD, Antisense Therapeutics are shortlisted for Duchenne muscular dystrophy (DMD) RNA therapy, and several gene therapies are favored by the FDA.
    today's article the Drug Ming Kant content team will do an inventory for you.
    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.

    , the university, has discovered the potential of tyhydroxycholic acid (THBAs) to treat bile siltation and metabolic diseases.
    THBAs are new bile acids that are not commonly found in mice or human bile, and in human liver cytotoxicity trials, THBA is less hydrophobic than UDCA (current standard treatment) and norUDCA (clinical development of PSC) and is more effective in standard bile siltation models.
    focuses on disease areas including PFIC and primary sclerotic bile rhinitis (PSC), and major preclinical candidates include QBT-002 and QBT-006.
    THBA also conducted trials in preclinical models of non-alcoholic fatty hepatitis (NASH) and obtained positive preliminary results.

    specific physiological mechanisms of the disease are not yet fully relevant.
    GT-AS is a gene therapy developed for the treatment of AS.
    gene therapy can target target brain regions in AS by delivering AAV vectors containing genetically modified UBUE3A encoded ubilin protein connective enzymes.
    in preclinical studies, GT-AS has been shown to restore protein expression and function.

    PBKR03 is a gene therapy in the study that uses the next generation of AAVhu68 vectors to pass on genetically modified coding semi-lactose ceramidease (GALC) to patient cells.
    PBKR03 will be injected into the cerebrospinal fluid through a single injection in the brain pool.

    MPS patients degrade glycoamine polysaccharide (GAGs) enzyme deficiency, resulting in the non-completely degradable mucosal polysaccharides in the lysosome build-up, which in turn leads to multi-system suffering, symptoms including facial abnormalities, bone deformities, liver and spleen enlargement.
    gene therapy, which contains genetically modified enzymes that encode missing enzymes in patients with MPS I, has the potential to be one of the most effective treatments for the disease.
