Not Applicable

Terminated

• Conditions: Secondary Progressive Multiple Sclerosis
• Interventions: Drug: SoluMedrol; Device: Extracorporeal Photopheresis

• Registration Number: NCT02296346
• Lead Sponsor: University of Utah

Brief Summary

In this research study, the investigators will determine whether a procedure called Extracorporeal Photopheresis (ECP) is helpful in preventing progression of disability in people with SPMS when compared to monthly corticosteroid infusions. This study will determine whether ECP has an effect on inflammatory cells in people with SPMS and whether it has a beneficial therapeutic effect.

Detailed Description

This is a Phase II randomized, open-label study to evaluate the efficacy of extracorporeal photopheresis (ECP) versus IVMP on disability progression in subjects with SPMS. At the initial screening visit, an extensive medical history will be obtained and a detailed neurological examination will be performed to determine eligibility. Subjects who meet eligibility criteria will be enrolled in one of two study arms. Subjects will be randomized at a 1:1 ratio to receive ECP (study arm) or active treatment with intravenous methylprednisolone pulses (control arm) administered every 4 Weeks (1 gram per infusion) for 52 weeks.

ECP will be administered according to the following schedule:

Study Arm: Weeks 1-8: 3 times per week Weeks 9-16: Twice per week Weeks 17-36: Treatment on two consecutive days every 2 weeks (or optionally, one treatment per week) Weeks 37-43: Once every 2 weeks Weeks 44-52: Once every 4 Weeks

All subjects, including patients who receive corticosteroids, will be evaluated using the MSFC tool at baseline and every 3 months through 2 years. They will also be scored using the EDSS at baseline and every 3 months through 2 years. Subjects in the control arm will be evaluated by MSFC and EDSS during the week prior to their next intravenous methylprednisolone infusion and every three months from baseline through two year mark. Blood will be collected for immune function (cytokines) testing at baseline, and months 3, 6, 9 and 12. MRI will be done at baseline as well as months 6 and 12 following initiation of treatment; if the disability measurements are stable or improved at any point in time, then ECP will be continued per protocol..

Patients in the ECP arm should have all of their treatments with the CELLEX ® System. Patients randomized to the ECP arm must receive their treatment within 5 days of baseline visit.

In the ECP process, UVADEX ® (methoxsalen) Sterile Solution will be injected directly the recirculation bag of the extracorporeal circuit after completion of the buffy coat collection. The dose of UVADEX® (methoxsalen) Sterile Solution will be calculated based on the standard treatment volume formula.

Exclusion Criteria

• Absolute medical contraindication to corticosteroid treatment

• Absolute medical contraindication to receive ECP

Extracorporeal Photopheresis	Extracorporeal Photopheresis	Patient will receive an Extracorporeal Photopheresis treatment at a set frequency over the course of 1 year. The treatment takes about 2-3 hours per session to complete. The treatment schedule is as follows: ECP will be administered according to the following schedule: Study Arm: Weeks 1-8: 3 times per week Weeks 9-16: Twice per week Weeks 17-36: Treatment on two consecutive days every 2 weeks (or optionally, one treatment per week) Weeks 37-43: Once every 2 weeks Weeks 44-52: Once every 4 Weeks

Primary Outcome Measures

Name	Time	Method
Multiple Sclerosis Functional Composite (MSFC) Z-score and Expanded Disability Status Scale (EDSS)	1 year	MSFC score is a composite score calculated from 3 tests: 1) Timed 25-Foot walk (leg function); 2) 9-Hole Peg Test (arm function); and 3) Paced Auditory Serial Addition Test (cognitive function). The results are combined to create a single score (the MSFC Z-Score) to measure performance and change over time in subjects with MS. MSFC Z-score = {Z arm + Z leg + Z cognitive} / 3.0. A positive score indicates that, on average, an individual performed better than the reference population and a negative score indicates that, on average, an individual performed worse than the reference population.; The Expanded Disability Status Scale (EDSS) is used to quantify disability due to symptoms of MS and to track changes in disability status over time. Scores range from 0 (normal neurological exam) to 10 (death due to multiple sclerosis). Scores are determined by performing a neurological exam and given in increments of 0.5.

Secondary Outcome Measures

Name	Time	Method
Immunological Parameters in Relation to SPMS	2 year	Changes in immunological parameters that occur following initiation of ECP or corticosteroids and any relevant correlation with clinical outcomes
