BAF-312(SiponiMod)

Описание

S1p signaling is important for immune, cardiovascular, and CNS function.Like its FDA approved predecessor fingolimod, siponimod is an oral S1p signaling modulator.While fin- golimod binds four out of five known S1p receptors, siponimod is selective for receptor sub- types 1 and 5. This selectivity may allow for an improved adverse event profile.

Побочные эффекты

Siponimod,2 mg/day, was studied in a Phase I placebo-controlled trial in patients with secondary progressive Ms.206The primary endpoint was time to 3 months confirmed dis- ability progression. There were substantive side effects from the drug，mainly increased liver transaminase concentrations,bradycardia, and bradyarrhythmia at treatment initiation.With subsequent siponimod administration，there was an increased incidence of macular edema, hypertension,varicella zoster reactivation, and convulsions compared to placebo. By grad- ually escalating the initial dose of siponimod, cardiac first-dose effects were reduced.While the results of this trial are encouraging,long- term safety issues may be a greater concern5or since persons with secondary progressive MS as a group are older,with a higher incidence of comorbidities that could preclude use of siponimod.
