Introduction to Apremilast
Apremilast, a phosphodiesterase 4 (PDE4) inhibitor, is a medication used primarily for the treatment of moderate to severe plaque psoriasis and psoriatic arthritis. Here, we will delve into the clinical trials, market analysis, and future projections for this drug.
Clinical Trials and Efficacy
Key Clinical Trials
Apremilast's FDA approval for moderate-to-severe plaque psoriasis was based on the results from the ESTEEM trials (ESTEEM-1 and ESTEEM-2). These trials involved 1257 patients and demonstrated significant improvements in psoriasis severity and quality of life outcomes.
- ESTEEM Trials: At week 16, the proportion of patients achieving a PASI 75 response was 33.1% and 28.8% in the apremilast groups of ESTEEM-1 and ESTEEM-2, respectively, compared to 5.3% and 5.8% in the placebo groups. Similarly, the sPGA scores of clear (0) or almost clear (1) were achieved by 21.7% and 20.4% of patients in the apremilast groups, versus 3.9% and 4.4% in the placebo groups[4].
Comparison with Other Treatments
A recent study compared the efficacy of apremilast with risankizumab, another treatment for psoriasis. This study showed that at week 16, 55.9% of patients treated with risankizumab achieved PASI 90, compared to 5.1% of those treated with apremilast. However, among patients who were nonresponders to apremilast and switched to risankizumab, 72.3% achieved PASI 90 by week 52, highlighting the potential benefit of switching treatments for nonresponders[1].
Adverse Events
Apremilast is associated with several adverse events, which can impact its use and patient compliance.
- Common Adverse Events: Diarrhea, nausea, headache, and weight loss are among the most frequently reported adverse events. Other side effects include vomiting, stomach pain, dizziness, loss of appetite, and sore throat[4].
