To evaluate the efficacy, safety, and tolerability of combination therapy with intramuscular interferon beta-1a and oral doxycycline, a potent inhibitor of matrix metalloproteinases, in patients with relapsing remitting multiple sclerosis (RRMS) having breakthrough disease activity.

Condition Intervention Phase
Multiple Sclerosis Drug: Interferon beta 1a, oral doxycycline Phase 4

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: An Open Label Trial of Safety and Efficacy of Combination Therapy With Interferon-B-1a and Oral Doxycycline in Patients With Relapsing-remitting Multiple Sclerosis (RRMS)

Primary Outcome Measures:
  • Gadolinium-enhancing (Gd+)Lesion Number Change. [ Time Frame: 8 months ]
    Before treatment is the number of lesions per image from months -3, -2, -1, and 0. During treatment is the number of lesions from months 1,2, and 3. The mean number of Gd+ lesions during each treatment period was calculated for each patient as the total number of Gd+ lesions observed across all images divided by the number of images. Hence, the mean number of Gd+ lesions per patient represents the number of lesions per MRI.

Secondary Outcome Measures:
  • Relapse Rates, Serum Matrix Metalloproteinase 9 Levels, Transendothelial Migration of Monocytes [ Time Frame: 8 months ]
    Only 1 patient relapsed. Correlations between decrease serum metalloproteinase 9 levels and enhancing lesion activity reduction. Transendothelial migration of monocytes was suppressed. Adverse effects were mild. No adverse synergistic effects of combination therapy.

  • Determine Safety and Tolerability of Combination Therapy With Avonex Plus Doxycycline [ Time Frame: 8 months ]
  • Determine Pre- and On-treatment Cytokine ELISA, MMP ELISA and Bioassay [ Time Frame: 8 months ]

Enrollment: 16
Study Start Date: December 2003
Study Completion Date: October 2009
Primary Completion Date: August 2009 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Interferon beta 1a, oral doxycycline
    Patients took intramuscular interferon beta 1a, 30 micrograms, for 3 months then added oral doxycycline, 100 daily with the interferon for 4 months.
