The Safety and Tolerability of STSA-1301 Subcutaneous Injection in Healthy Subjects

Staidson Biopharmaceuticals Co., Ltd is conducting a phase one study to assess the safety of using a new drug, STSA-1301 in health subjects without ITP. If determined to be safe, the drug will then be tested in a different phase of the trial in ITP patients. STSA-1301 is a recombinant anti-human FcRN humanized IgG4 monoclonal antibody with high affinity. It brings to the FcRN receptor losing its ability to bind to IgG which accelerates IgG degradation without affecting IgM or IgA. This, the treatment is hoped to be helpful in treating autoimmune diseases, like ITP, when mediated by pathogenic IgG antibodies.

The trial will begin with a phase IIa trial, consisting of a screening, treatment, and safety follow up period. Individuals between 18-80 years old with persistent or chronic ITP (>3 months from diagnosis) and have failed to respond to 1+ first-line ITP therapies are eligible to enrol. Individuals who had hemorrhage 4 weeks prior to screening, history of blood disorders other than ITP, cancer, organ transplantation, or have an active infection will be excluded. The selection criteria for the phase IIb trial will be released after obtaining a better understanding of the efficacy, risks, and benefits of the therapy upon completion of the phase IIa trial.

The Combination of Iguratimod and Danazol as the Treatment of Steroid-Resistant/Relapse Immune Thrombocytopenia

Peking University People's Hospital is conducting a randomized control, multicenter, open-label study to look at the clinical benefit of using a combination of Iguratimod and Danazol together vs Danazol alone for the treatment of primary ITP in adults between the ages of 18-70 years. Iguratimod is a non-steroid anti-inflammatory disease-modifying anti-rheumatic drug (DMARD), a newer therapy used to treat patients with Rheumatoid Arthritis. It works by acting on T- and B-cells in the immune system and can inhibit the expression of various inflammatory factors in the body. The study is looking to recruit 100 adult participants who are steroid-resistant or steroid-dependant, i.e., patients who do not have a significant platelet increase in response to steroid treatment, or patients who are unable to wean off steroids without risking a decrease in their platelet count. Participants must have a platelet count less than 30,000/μL. Participants will be excluded it they have congestive heart failure, an arrhythmia, are pregnant or nursing, or have HIV, cancer, lupus, H.pylori, certain metabolic conditions, Hepatitis C (HCV) or other infections causing thrombocytopenia.
