Treatment Options for Managing Multiple Sclerosis (MS) Symptoms
Disease-modifying therapies (DMTs) are the cornerstone of MS treatment, with options ranging from injectable interferons to high-efficacy monoclonal antibodies, while autologous hematopoietic stem cell transplantation (AHSCT) should be considered for patients with highly active disease that fails to respond to high-efficacy DMTs. 1, 2
First-Line Disease-Modifying Therapies
- Injectable therapies including interferon beta-1b and interferon beta-1a reduce relapse rates and delay disability progression in relapsing forms of MS 3, 4
- Oral medications such as fingolimod are indicated for relapsing forms of MS, including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease 5
- DMTs can reduce annual relapse rates by 29-68% compared to placebo or active comparators 1
- Early initiation of DMTs has been shown to improve long-term outcomes and delay conversion to clinically definite MS in patients with clinically isolated syndrome 6
Treatment Escalation for Active Disease
- For patients with highly active disease despite first-line therapy, escalation to high-efficacy DMTs should be considered 2
- High-efficacy DMTs typically include monoclonal antibodies such as alemtuzumab, natalizumab, ocrelizumab, and ofatumumab 7
- Early escalation to high-efficacy therapy is more effective than stepped care approaches, particularly for patients showing signs of aggressive disease 7
- Markers of aggressive disease include frequent relapses, incomplete recovery from relapses, high frequency of new MRI lesions, and rapid onset of disability 7
Autologous Hematopoietic Stem Cell Transplantation (AHSCT)
AHSCT should be considered for patients with highly active MS in whom high-efficacy DMT has failed 7
Optimal candidates for AHSCT include: 7
- Patients under 45 years of age
- Disease duration less than 10 years
- High focal inflammation on MRI
- EDSS score less than 4.0
- Absence of cognitive impairment
- Relapsing-remitting MS (rather than progressive forms)
AHSCT is not recommended for patients with: 7
- Age over 55 years
- Disease duration greater than 20 years
- Absence of inflammatory activity
- EDSS score greater than 6.0
- Major cognitive impairment
- Secondary progressive MS without evidence of inflammatory activity
Management of MS Flares/Relapses
- Corticosteroids are the primary treatment for acute MS flares 2
- MRI follow-up should be conducted within 3-12 months after a flare, including T2-weighted, FLAIR, and T1-weighted sequences with gadolinium enhancement 2
- For patients with incomplete recovery after initial corticosteroid treatment, evaluation for DMT adjustment is recommended 2
- Rehabilitation strategies should be implemented as soon as possible after the acute phase of treatment 2
Special Considerations for Progressive MS
- Ocrelizumab is approved for primary progressive MS 1
- AHSCT can be considered for young (<45 years) individuals with early progressive MS who have a short disease duration and well-documented clinical and radiological evidence of inflammatory disease 7
- AHSCT is not recommended for progressive MS without detectable inflammatory lesion activity due to lack of evidence 7
- For patients with long-standing, advanced forms of MS with severe disability, AHSCT is not recommended due to high risk and low or no benefit 7
Practical Approach to MS Treatment
- Begin with appropriate DMT based on disease activity and patient factors 1, 8
- Monitor disease activity through clinical evaluation and MRI imaging 2
- For patients with breakthrough disease activity despite DMT, consider escalation to higher-efficacy therapy 7
- Refer patients with highly active, treatment-refractory MS as early as possible for consideration of AHSCT 7
- For patients with markers of aggressive disease, AHSCT can be considered after failure of a single high-efficacy DMT 7
Pitfalls and Caveats
- Delayed initiation of treatment and poor adherence to DMTs are associated with worse outcomes 6
- Progressive MS remains an area with limited disease-modifying treatment options 9
- AHSCT carries higher acute risks than many approved DMTs, so patient selection is critical 7
- The long-term benefits of many DMTs remain unclear despite their efficacy in reducing relapse risk 8
