Minocycline for Acute Ischemic Stroke Undergoing Endovascular Treatment Due to Basilar Artery Occlusion (MIST-B)

This is a multi-center, evaluator-blinded, randomized, open-label, proof of concept trial to explore possible beneficial effect of adjunctive oral minocycline on acute ischemic stroke (AIS) undergoing endovascular treatment due to basilar artery occlusion (BAO). Minocycline has excellent safety profiles, have been previously demonstrated individually to reduce infarction in animal models of stroke, and have potentially mechanisms of antioxidant, anti-inflammatory, anti-apoptotic and protection of blood-brain barrier. However, it is not known whether minocycline can reduce futile recanalization of endovascular treatment, and improve the outcome of patients with AIS due to BAO. Eligible and willing subjects will be randomly assigned to the treatment group or the control group. The treatment group will receive 200 mg oral minocycline, followed by 100 mg every 12 hours times for a total of 5 days. Both groups will receive endovascular thrombectomy and standard medical. The treatment with minocycline will start as soon as possible after randomization. Considering the risk of difficulty in feeding tube before EVT, minocycline administered within one hours after EVT is acceptable. Measures of stroke severity and disability will be recorded at baseline and through the follow-up periods (90 days). The evaluator will be blind to the allocation of patients further minimizing the bias.

Minocycline for Chronic Autoimmune Uveitis

Autoimmune uveitis is one kind of non-infectious, sight-threatening, relapsing and severe ocular disease. Approximately 20%-25% autoimmune uveitis patients suffer from the dilemma of blindness for the chronic and persistent inflammatory state in the eyes, which results in continuous destroy in the structure of the eyes and gradually leads to irreversible damage on visual function. However, it shows limiting efficacy of current treatment including glucocorticoids, immunosuppressant and biologics for chronic autoimmune uveitis. Minocycline has been regarded to have anti-apoptosis and immunemodulatory function for decades and it has been illustrated to be beneficial in several neuro-degenerative and neuro-inflammatory diseases. This trial aims to investigate the efficacy and safety of minocycline for chronic autoimmune uveitis with retinal degenerative changes.
