AHSCT With Fludarabine and Cyclophosphamide Based Conditioning Regimes in Patients With Multiple Sclerosis
Trial of the Efficacy and Safety of High-dose Immunosuppressive Therapy Based on Fludarabine and Cyclophosphamide-containing Conditioning Regimen Followed by Autologous Hematopoietic Stem Cell Transplantation in Patients With Multiple Sclerosis.
One of the possible options for the treatment of MS at present is a high-dose immunosuppressive therapy followed by autologous hematopoietic stem cell transplantation (HIST-AHSCT), which is a highly effective treatment for patients with relapsing-remitting MS.
This method of MS treatment was introduced in 1997. Significant complications and mortality associated with HIST-ATHSC is an obstacle to broad use of this method. The risk is even greater in patients with advanced disease, long duration of previous treatment and aggressive forms of MS.
Despite toxicity certain progressive cases of MS are still an indication for HIST-autoHSCT.
Most commonly used conditioning regimens for multiple sclerosis include high-dose cyclophosphamide. One of the options to reduce cyclophosphamide-related toxicity and dose is addition of fludarabine. Fludarabine is a cytostatic drug, an antimetabolite from the group of purine antagonists. It has a pronounced immunosuppressive activity and no overlapping toxicity with cyclophosphamide. The study will evaluate the safety and efficacy of this combination.

Intervention / Treatment |
---|---|
Experimental: AHSCT: FluCy200
AHSCT with reduced intensity condition regimen (RIC): cyclophosphamide intravenously at a dose of 50 mg/kg/day from -5 to day -2 inclusive; fludarabine intravenously at a dose of 30 mg/m2 from -5 to day -2 inclusive. Immunotherapy: ATG - ATGAM intravenously 20 mg/kg from -3 to -1 or Thymoglobulin 2.5 mg/kg from -3 to -1 day. Also, within the framework of immunotherapy, instead of ATG, it is allowed to use anti-B-cell therapy - Rituximab 500 mg / m2 per day +12 AHSCT. |
Intravenous injection of fludarabine phosphate at a dose of 30 mg/m2 from day -5 to day -2 of immunoablative conditioning regimen.

Multiple sclerosis-specific questionnaire - Multiple Sclerosis Impact Scale (MSIS-29) before and after AHSCT: The MSIS-29 scale consists of 29 items and includes indicators observed over the previous two weeks, including 20 of which characterize physical condition, coordination and mobility, and 9 questions reflect the patient's mental state. Answers are ranked on a 5-point Likert scale from 1 to 5 (1 = none; 2 = little; 3 = moderate; 4 = significant; 5 = very strong) in one direction. The total score is the sum of all 29 responses and can range from 29 to 145. A higher score means a higher degree of disability. The result is assessed on a scale from 0 to 100, where a higher result means worse health. |
