Multiple sclerosis (MS) is a chronic inflammatory disease associated with central nervous system (CNS) demyelination and subsequent axonal degeneration. Multiple sclerosis exhibits an unpredictable and variable clinical course.

Multiple sclerosis plaques contain numerous types of cells and infiltrating macrophages have been identified to contribute significantly to demyelination in both clinical MS and animal models of MS. Granulocyte-macrophage colony-stimulating factor (GM CSF) stimulates proliferation and activation of macrophages, monocytes, neutrophils, eosinophils, dendritic cells and microglia with subsequent induction of proinflammatory biomolecules.

Therefore blocking GM CSF activity might be a therapeutic approach for the treatment of MS.

Further study details as provided by MorphoSys AG:

Primary Outcome Measures:
  • Incidence and severity of adverse events [ Time Frame: Up to 20 weeks ] [ Designated as safety issue: Yes ]
    To determine the safety of multiple doses of MOR103 in patients with relapsing-remitting or secondary progressive MS (RRMS or SPMS. Safety will be evaluated by assessing adverse events, clinical lab data and vital signs.

Secondary Outcome Measures:
  • Pharmacokinetic profile [ Time Frame: Six time points up to 20 weeks ] [ Designated as safety issue: No ]
    Pharmacokinetic profile assessments comprise of the measuremnt of several standard PK parameters (e.g. Cmax, Tmax, t1/2)

  • Potential immunogenicity of MOR103 [ Time Frame: 4 time points up 20 weeks ] [ Designated as safety issue: No ]
    To determine development of anti-MOR103 antibodies

Detailed Description:

Recent clinical studies demonstrated a possible dysregulation of the balance of pro and anti inflammatory lymphocytes, which may contribute to the pathogenesis of MS.

It was shown in animal models of EAE that during the disease effect or phase GM CSF sustained neuroinflammation via myeloid cells that infiltrate the CNS proving an essential role of GM CSF in encephalitogenicity.


Ages Eligible for Study:   18 Years to 60 Years

Key Inclusion Criteria:

Outpatients with a diagnosis of RRMS or SPMS, who are currently not being treated and who have at least 1 of the following:

  • At least 1 documented relapse within 1 year before Screening, or
  • Two documented relapses within the past 2 years before Screening, or
  • A new gadolinium (Gd)-enhancing lesion on magnetic resonance imaging (MRI) T1-weighted imaging within 1 year before Screening, or
  • A new T2 lesion on MRI within 1 year before Screening. The patient must have 10 or less, Gd-enhancing lesions per T1-weighted MRI at Screening as assessed by a central reader.

    • Cytotoxic agents, any immunosuppressive/immunomodulating agents
  3. A patient who has not stabilized, in the opinion of the investigator
  4. A patient with any medical condition or uncontrolled disease states other than MS requiring or likely to require systemic treatment with corticosteroids or other immune compromising agents
  5. A patient with current or a history of major chronic inflammatory autoimmune diseases other than MS
  6. A patient with any type of infection
