Brief Summary:
Open-label study to evaluate the effectiveness of treatment with ofatumumab in subjects transitioning from any fumarate-based RMS approved therapy or fingolimod due to breakthrough disease.

Condition or disease Intervention/treatment Phase
Relapsing Multiple Sclerosis Biological: Ofatumumab Phase 3

Detailed Description:
This is a single arm, prospective, multicentre and open-label, 96-week study to evaluate the treatment effectiveness of ofatumumab (OMB) in subjects with relapsing multiple sclerosis (RMS) transitioning from fumarate-based RMS approved therapies, such as dimethyl fumarate (DMF), diroximel fumarate (DRF), and monomethyl fumarate (MMF), or fingolimod due to breakthrough disease activity.

Drug Information available for: Ofatumumab

Arm Intervention/treatment
Experimental: Ofatumumab
Ofatumumab 20 mg subcutaneous injections every 4 weeks, following loading of 3 doses in the first 14 days
Biological: Ofatumumab
Subjects will receive ofatumumab injections in an autoinjector (AI) for subcutaneous administration containing 20 mg ofatumumab (50 mg/ml, 0.4 ml content)
Other Name: OMB157

Primary Outcome Measures :
  1. Annual Relapse Rate (ARR) [ Time Frame: Up to 96 weeks from baseline ]
    ARR is the number of confirmed relapses in a year calculated based on cumulative number of relapses by patient adjusted for time-in-study by patient

Secondary Outcome Measures :
  1. Safety evaluation [ Time Frame: 96 weeks ]
    Proportion of patients with adverse events, including injection related reactions, abnormal laboratory results or vital signs, as well as proportion of patients discontinuing treatment due to insufficient effectiveness or tolerability/safety reasons

  • Breakthrough disease activity while the participant was adequately using fumarates or fingolimod prior to transitioning for a minimum of 6 months as evidenced by one or more clinically reported relapses or one or more signs of Magnetic Resonance Imaging (MRI) activity (e.g. Gd+ enhancement, new or enlarging T2 lesions)
  • Neurologically stable within one month prior to first study drug administration

Exclusion Criteria:

  • Pregnant or nursing (lactating) women
  • Women of child-bearing potential unless they are using highly effective forms of contraception during dosing and for at least 6 months after stopping study medication
  • Subjects with active chronic disease of the immune system other than MS or with immunodeficiency syndrome
  • Subjects with active systemic bacterial, fungal or viral infections (such as hepatitis, HIV, COVID-19), or known to have Acquired Immunodeficiency Syndrome (AIDS)
  • Subjects with neurological symptoms consistent with Progressive Multifocal Leukoencephalopathy (PML) or with confirmed PML
  • Subjects at risk of developing or having reactivation of syphilis or tuberculosis (e.g. subjects with known exposure to, or history of syphilis, or active or latent tuberculosis, even if previously treated), as confirmed by medical history or per local practice
  • Subjects with active hepatitis B and C disease, assessed locally
  • Have received any live or live-attenuated vaccines within 4 weeks prior to first study drug administration
  • Have been treated with medications as specified or within timeframes specified (e.g. corticosteroids, ofatumumab, rituximab, ocrelizumab, alemtuzumab, natalizumab, daclizumab, cyclophosphamide, teriflunomide etc.)
  • Subjects suspected of not being able or willing to cooperate or comply with study protocol requirements in the opinion of the investigator
