Clinical effects of MND-19 (Inosiplex) on subacute sclerosing panencephalitis--a multi-institutional collaborative study--The Inosiplex-SSPE Research Committee.

A total of 151 cases of subacute sclerosing panencephalitis (SSPE), comprising 89 cases treated with MND-19 (Inosiplex) and 62 untreated cases, were retrospectively investigated as to background characteristics, survival rate and clinical course in order to compare the findings in the 2 groups of cases. The survival rate for the cases treated with MND-19 (MND-19-treated group) was significantly higher than that for the untreated cases (control group), which was also true on stratified analysis or on smoothing of the background factors by means of Cox's multiple regression model. Investigation of the clinical course revealed that progression through the disease stages was significantly slow in the MND-19-treated group, compared with in the control group. Global rating of the clinical course showed that a prolonged remission was obtained in more MND-19-treated cases than control cases. The measles virus antibody titer was in no way affected in the former group. Side effects of MND-19 were observed in 17 of the 89 treated cases (19.1%).
