Abstract
Epilepsy is defined as "drug-resistant" when existing anti-epileptic drugs (AED) are found to have minimal to no effect on patient's condition. Therefore the search and testing of new treatment strategies is warranted. This study focuses on the effects of autologous mesenchymal stem cells (MSC) in drug-resistant epilepsy patients within a Phase I/II open-label registered clinical trial NCT02497443. A total of 67 patients was included (29 males, 38 females, mean age 33 ± 1.3 yo). The patients received either standard treatment with AEDs, or AEDs supplemented with one or two courses of therapy with autologous bone marrow-derived MSCs expanded in vitro. MSC therapy courses were 6 months apart, and each course consisted of two cell injections: an intravenous infusion of MSCs, followed within 1 week by an intrathecal injection. Primary outcome of the study was safety, secondary outcome was efficacy in terms of seizure frequency reduction and response to treatment. MSC injections proved safe and did not cause any severe side effects. In MSC group (n = 34), 61.7% patients responded to therapy at 6 months timepoint (p < 0.01 vs control, n = 33), and the number rose to 76.5% by 12 months timepoint. Decrease in anxiety and depression sco...Continue Reading
