E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objectives of this study are to assess the efficacy, safety, and tolerability of a once daily oral dose
of laquinimod (0.6 or 1.5 mg) compared to placebo in PPMS patients. |
|
E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Sub-studies (Ancillary studies) are described within the current core study protocol.
Some of these studies may be performed only in selected sites and in accordance with local regulations as applicable.
1. Pharmacokinetc Variables: Pharmacokinetics of laquinimod will be evaluated
2. Potential Biomarker Measures: Potential biomarker assessments to better understand laquinimod MoA, as well as to explore response predictive markers for efficacy or safety
3.Pharmacogenomic Variables: PGx analyses to investigate the association between genetic sequence polymorphisms and/or gene and clinical response including unexpected adverse events.
4. Cerebrospinal fluid (CSF) assessment: to explore putative neuroprotective effects of laquinimod
5. Optical coherence tomography (OCT) assessment: used as a tool for visualizing the processes of
neurodegeneration, neuroprotection, and neurorepair in MS.

2. Baseline magnetic resonance imaging (MRI) showing lesions consistent with PPMS in either or both brain and spinal cord

screening and baseline visits
4. Documented evidence of clinical disability progression in the 2 years prior to screening.

6. Patients must be between 25 to 55 years of age, inclusive
7. Women of child-bearing potential must practice an acceptable method of birth control for 30 days before taking the study drug, and 2 acceptable methods of birth control during all study duration and until 30 days after the last dose of treatment is administered.

2. Progressive neurological disorder other than PPMS.
3. Any MRI record showing presence of cervical cord compression.
4. Baseline MRI showing other findings (including lesions that are atypical for PPMS) that may explain the clinical signs and symptoms.

7. Use of experimental or investigational drugs in a clinical study within 24 weeks prior to baseline. Use of a currently marketed drug in a clinical study within 24 weeks prior to baseline would not be exclusionary, provided no other exclusion criteria are met.
8. Use of immunosuppressive agents, or cytotoxic agents, including cyclophosphamide and azathioprine
within 48 weeks prior to baseline.
9. Previous treatment with fingolimod (GILENYA®, Novartis), dimethyl fumarate (TECFIDERA®, Biogen

immunoglobulin, or plasmapheresis within 8 weeks prior to baseline.
10. Use of teriflunomide (AUBAGIO®, Sanofi) within 2 years prior to baseline, except if active washout (with either cholestyramine or activated charcoal) was done 2 months or more prior to baseline.
11. Prior use of monoclonal antibodies ever, except for:
a. natalizumab (TYSABRI®, Biogen Idec Inc), if given more than 24 weeks prior to baseline AND the
patient is John Cunningham (JC) virus antibody test negative (as per medical history)
b. rituximab, ocrelizumab, or ofatumumab, if B cell count (CD19, as per medical history) is higher than
80 cells/μL
12. Use of mitoxantrone (NOVANTRONE®, Immunex) within 5 years prior to screening. Use of mitoxantrone >5 years before screening is allowed in patients with normal ejection fraction and who did not exceed the total lifetime maximal dose.
13. Previous use of laquinimod.
14. Chronic (eg, more than 30 consecutive days or monthly dosing, with the intent of MS disease modification) systemic (intravenous, intramuscular or oral) corticosteroid treatment within 8 weeks prior to baseline.
15. Previous use of cladribine or alemtuzumab (LEMTRADA®, Sanofi).
16. Previous total body irradiation or total lymphoid irradiation.
17. Previous stem cell treatment, cell-based treatment, or bone marrow transplantation of any kind.
18. Patients who underwent endovascular treatment for chronic cerebrospinal venous insufficiency (CCSVI) within 12 weeks prior to baseline.
19. Use of moderate/strong inhibitors of cytochrome P450 (CYP) 3A4 within 2 weeks prior to baseline.
20. Use of inducers of CYP3A4 within 2 weeks prior to baseline.
21. Pregnancy or breastfeeding.
22. Serum levels ≥3× upper limit of the normal range (ULN) of either alanine aminotransferase (ALT) or
aspartate aminotransferase (AST) at screening.
23. Serum direct bilirubin which is ≥2×ULN at screening.
24. Patients with a clinically significant or unstable medical or surgical condition that (in the opinion of the Investigator) would preclude safe and complete study participation, as determined by medical history, physical examinations, electrocardiogram (ECG), laboratory tests or chest X-ray.
25. A known history of hypersensitivity to gadolinium (Gd).
26. Glomerular filtration rate (GFR) < or equal 60 mL/min at screening visit.
27. Inability to successfully undergo MRI scanning, including claustrophobia.
28. Known drug hypersensitivity that would preclude administration of laquinimod, such as hypersensitivity to mannitol, meglumine or sodium stearyl fumarate. |
