What the trial was testing
The MOSAIC enrolled 123 patients with psoriasis. The study was sponsored by Amgen and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was long-term safety (phase 4). Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
Apremilast reduced joint inflammation on MRI scans, and 66% of patients stayed on the treatment for a full year.

These findings — that completed a full year of treatment — were published in the The Lancet. Rheumatology and represent the headline result of the study.
Researchers tracked outcomes across 123 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with psoriasis, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
This treatment is already FDA-approved for psoriatic arthritis. If you have joint pain and swelling from psoriasis, this pill might help reduce inflammation throughout your body. Ask your doctor if apremilast could work for you, especially if you haven't responded well to other treatments.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

Creating Health Course Study for People With Rheumatological Conditions and Mood Disorders
The goal of this project is to critically evaluate the effectiveness of an online health program designed to improve diet and self-care in patients with rheumatological conditions, including rheumatoid arthritis (RA), Sjogren's syndrome (SS), systemic lupus erythematosus (SLE), mixed connective tissue disease (MCTD), psoriatic arthritis (PsA), anxiety disorders, depressive disorders and moderate depression. Additionally, investigators will assess the program's effectiveness, as well as the challenges and facilitators involved in using an online wellness program to reduce fatigue and enhance the quality of life in patients suffering from these conditions.
