Enbrel 2x/week dose shown safe for 2 years

Results of a 96-week study of Enbrel (etanercept) showed it was safe and effective for the duration of the study period. Given how long psoriasis patients have to take medications, this is good news. (The FDA typically makes its determination about a psoriasis treatment based on a 12-week period.)

Of course, this cannot answer the 15- or 25-year safety question, which can only come after the treatment has been used for that long.

The study was of the larger (twice-a-week) Enbrel dose that many patients prefer (but which costs more).
