Introduction to Extavia
Extavia, containing the active substance interferon beta-1b, is a medication authorized for the treatment of multiple sclerosis (MS), a chronic and often disabling autoimmune disease that affects the central nervous system. Here, we will delve into the clinical trials, market analysis, and projections for Extavia.
Clinical Trials and Efficacy
Extavia has been extensively studied in various clinical trials to assess its efficacy and safety in treating different forms of MS.
Relapsing-Remitting MS
In a two-year study involving 338 patients with relapsing-remitting MS, Extavia demonstrated a significant reduction in the number of annual relapses compared to placebo. Patients receiving Extavia had an average of 0.84 relapses per year, whereas those on placebo had 1.27 relapses per year[1][4].
Secondary Progressive MS
Extavia was also studied in 1,657 patients with secondary progressive MS in two separate trials. One of these studies showed a significant delay in the time to disability progression and in the time to becoming wheelchair-bound, with a 31% risk reduction due to Extavia. Both studies demonstrated a 30% reduction in the number of clinical relapses[1].
Early MS
A study involving 487 patients with a single demyelinating event showed that treatment with Extavia for two years reduced the risk of developing clinically defined MS. Only 28% of patients who received Extavia developed MS, compared to 45% of those who received placebo[1].
Mechanism of Action
Extavia works by calming down the immune system, which in MS, malfunctions and attacks the central nervous system. The exact mechanism is not fully understood, but interferon beta-1b is known to reduce inflammation and prevent relapses of MS[1].
Side Effects and Contraindications
Common side effects of Extavia include flu-like symptoms such as fever, chills, joint pain, and reactions at the site of injection. These side effects are more frequent at the beginning of treatment but tend to decrease over time. Extavia is contraindicated in patients with severe depression or thoughts of suicide and in those with decompensated liver disease[1].
Market Analysis
Global Market Size and Growth
The global multiple sclerosis drugs market, which includes Extavia, has been growing steadily. In 2016, the market was valued at $16.13 billion and is expected to reach $27.38 billion by 2025, growing at a CAGR of 6.3% from 2017 to 2025[2].
