Brief Summary:


In people with multiple sclerosis (MS), brain and cerebrospinal fluid (CSF) biomarkers indicate inflammation or disease. Researchers want to see if 4 drugs given alone or combined affect MS biomarkers. They want to see if a change in biomarker levels can predict which drugs a person with MS might respond to.


To see if signs of inflammation in CSF help predict a person s response to different drugs.


People ages 18 and older who:

  • Are in protocol 09-I-0032
  • Have progressive MS
  • Can stand and walk a few steps
  • Take an MS drug


Participants will be screened in protocol 09-I-0032.

Participants will take 1 of the 4 study drugs. Researchers will call after 1 month to see how they are doing. Some will start a second drug. They may take each drug or combination for up to 18 months.

Participants will have 2 visits a year for up to 6 years. Visits include:

  • Medical history
  • Physical exam
  • Blood and heart tests
  • X-rays and scans
  • Eye exam and tear collection
  • Lumbar puncture: A needle inserted between back bones removes some CSF.
  • Lymphocytapheresis: Blood is removed through a needle in one arm and run through a machine. The blood is returned through a needle in the other arm.
  • A sensor on the forehead records blood flow and oxygen use.
  • Participants may get a device for testing at home.

Participants will stop taking the drugs if they have taken 2 drugs together for 18 months or if they do not do well on the drugs.

Participants will be called 3 months later to see how they are doing.

Arm Intervention/treatment
Experimental: Pioglitazone
Pioglitazone Monotherapy

Experimental: Montelukast
Montelukast Monotherapy
Drug: Montelukast
10mg qd

Primary Outcome Measures :
  1. Primary outcome will be the change in the CombiWISE progression rate at the end of monotherapy plus combination therapy period in comparison to projected baseline disability progression. [ Time Frame: Study Completion ]

Secondary Outcome Measures :
  1. Safety and tolerability of individual drugs and their combinations [ Time Frame: Study Completion ]
  2. Change in the rate of ventricular atrophy between baseline, monotherapy and combination therapy periods, measured by linear regression slopes greater than or equal to 3 time-points for each period [ Time Frame: Study Completion ]
  3. Correlations between change(s) in CSF biomarkers and clinical efficacy (systems biology approach analyzing drugs/combinations separately and combining all drugs/combinations to a single larger cohort; exploratory analysis) [ Time Frame: Study Completion ]
  4. Development of new CSF (combinatorial) biomarkers, new clinical scales, new MRI outcomes will be included in exploratory analyses [ Time Frame: Study Completion ]

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
  • Enrolled in 09-I-0032 protocol
  • Clinically definite MS
  • Age greater than or equal to 18 at time of study enrollment
  • Expanded Disability Status Scale (EDSS) 1.0-7.5
  • Documented sustained clinical progression of at least 0.5 CombiWISE points/year (measured by greater than or equal to 4 time-points regression analysis of CombiWISE values spanning at least 1.5 years in total)
  • Subjects of childbearing potential must be willing to use a medically acceptable form of birth control, which includes abstinence, while being treated on this study
  • Patients who desire to continue their current FDA-approved DMTs based on its perceived (partial) therapeutic benefit will be enrolled with the understanding that the underlying FDA-approved therapy has to remain stable during this protocol. If patient desires and/or his/her medical condition requires changing FDA-approved DMT during the duration of this protocol, the drugs administered under this protocol will be withdrawn, but the patient will have an option to repeat the entire process: go back to greater than or equal to 1.5 year baseline period on new DMT to verify that the rate of progression remains greater than or equal to 0.5 CombiWISE points/year and then can be matched to the same monotherapy or combination therapy regimen s/he was on before the immunomodulatory DMT change.
  • Willing and able to participate in all aspects of the protocol
  • Able and willing to provide informed consent


  • Clinically significant medical disorders that, in the judgment of the investigators, could expose the patient to undue risk of harm or prevent the patient from safely completing all required elements of the study (such as, but not limited to significant cerebrovascular disease, ischemic cardiomyopathy, clotting disorder, other neurodegenerative disorder, substance abuse or significant psychiatric disorder such as depression with suicidal ideations, unable to perform or tolerate MRI examinations)
  • Clinically significant medical disorders, other than MS, that require chronic treatment with immunosuppressive or immunomodulatory agents
  • Pregnancy or Breastfeeding
  • Abnormal screening/baseline blood tests exceeding any of the limits defined below:
  • Serum alanine transaminase or aspartate transaminase levels which are greater than three times the upper limit of normal values.

  • Platelet count less than 85,000/mm^3
  • Serum creatinine level greater than 2.0 mg/dl and eGFR (glomerular filtration rate) less than 60

    • Serological evidence of HIV, HTLV-1 or active hepatitis A, B or C
