Study Description

Brief Summary:

A single arm study evaluating the continued efficacy, safety and tolerability of ofatumumab in patients with relapsing multiple sclerosis who are transitioning from aCD20 mAb therapy

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

Detailed Description:

This is a single-arm multi-center, study in approximately 100 participants with relapsing multiple sclerosis who were previously treated with aCD20 mAb therapy. Eligible participants will receive open label ofatumumab 20 mg subcutaneous monthly for 12 months following initial loading regimen of 20 milligrams subcutaneous doses on Days 1, 7 and 14. Assessments will include but are not limited to Magnetic Resonance Imaging (MRI) assessed for quality by central reading center, multiple Patient Reported Outcome measurements and safety assessments. Participants that do not continue onto commercial ofatumumab or another therapy within one month of the End of Study Visit must continue into the safety Follow Up phase, consisting of every 3 month visits including B cell monitoring until they are able to start on commercial ofatumumab or switch to another therapy or until their B cells are repleted defined as a B cell concentration greater than the individual participant's baseline value or greater than the lower limit of normal. All participants will have a safety follow-up phone call at 30 days post study.

Experimental: Ofatumumab; Investigational drug will be provided in an autoinjector for subcutaneous administration containing 20 mg ofatumumab (20 mg/0.4 ml) administered at baseline, Day 7, Day 14 and monthly thereafter	Drug: Ofatumumab; Investigational drug will be provided in an autoinjector for subcutaneous administration containing 20 mg ofatumumab (20 mg/0.4 ml); Other Name: OMB157

Outcome Measures

Primary Outcome Measures :

1. Number of participants with no change or reduction in gadolinium enhancing lesions at 12 months [ Time Frame: Baseline up to 12 months ]
   Magnetic Resonance Imaging (MRI) will be used to measure presence of new or reduction in number of gadolinium enhancing lesions. Each MRI scan will be previewed by a local neuroradiologist. The quality of each scan performed will be assessed by a central MRI reading center and evaluated for quality, completeness and adherence to the protocol.

Secondary Outcome Measures :

1. Change from baseline for total CD19+ B cell counts and CD3+CD20+ T cell counts, [ Time Frame: Baseline up to 6 and 12 months ]
   Total CD19+ B cell counts cell counts, obtained by fluorescence activated cell sorting
2. Change from baseline for CD3+CD20+ T cell counts, [ Time Frame: Baseline up to 6 and 12 months ]
   CD3+CD20+ T cell counts, obtained by fluorescence activated cell sorting
3. Change from baseline for Treatment Satisfaction Questionnaire for Medication (TSQM-9) [ Time Frame: Baseline up to 6 and 12 months ]
   The Treatment Satisfaction Questionnaire for Medication (TSQM-9) will be used to evaluate the participants' satisfaction with Ofatumumab. The TSQM-9 is a psychometrically sound and valid participant reported outcome to measure participants' satisfaction with medication and a good predictor of adherence across different types of medication and participant population. The TSQM-9 is a 9 item questionnaire having a global satisfaction score ranging from 0-100. The questionnaire consists of 3 domains: satisfaction, convenience and effectiveness (3 items each). The domain scores range from 0 to 100 with higher scores representing higher satisfaction on that domain.
4. Change from baseline in Columbia-Suicide Severity Rating Scale (C-SSRS) [ Time Frame: Baseline up to 6 and 12 months ]
   The C-SSRS rates an individual's degree of suicidal ideation (SI) on a scale, ranging from "wish to be dead" to "active suicidal ideation with specific plan and intent." The scale identifies SI severity and intensity, which may be indicative of an individual's intent to commit suicide. C-SSRS SI severity subscale ranges from 0 (no SI) to 5 (active SI with plan and intent).
5. Number of participants with treatment emergent adverse events [ Time Frame: Baseline up 13 months (includes 30 day followup) or up to 21 months for patients entering extra safety follow-up ]
   Adverse event monitoring should be continued following the last dose of study treatment until B cells are repleted. Repletion is defined as a concentration > the participant's baseline value or > the lower limit of normal, whichever is observed first.

There is presently no contraindication for the use of an inactivated, viral-vector-or mRNA based Sars-CoV-2 vaccine in patients who are immunocompromised. However, different Sars-CoV-2 vaccines may have various mechanisms of action and different associated potential risks. Please review local prescribing information of any specific Sars-CoV-2 vaccine and comply with local prescribing information requirements for specific contra-indications and special warnings and precautions for use.
