Psoriasis Treatment: What’s in the Future?
Biologic Agents as Psoriasis Treatment continued...
The biologic agents approved by the FDA for treatment of moderate to severe psoriasis include:
- Etanercept (Enbrel), a TNF-alpha blocker
- Adalimumab (Humira), a TNF-alpha blocking antibody
- Infliximab (Remicade), a TNF-alpha blocker
Ustekinumab (Stelara),a human antibody against interleukins
Biologic agents work well for treating psoriasis: in clinical trials, each of the medicines reduced psoriasis activity by at least 75% in many people. However, these new psoriasis medicines have drawbacks. Biologic agents for psoriasis treatment can cost hundreds or thousands of dollars per month. Although safe for most people, close monitoring is needed for an increased risk of infection, cancer, and other complications.
Otezla is an oral drug approved to treat psoriatic arthritis and plaque psoriasis in adults. It's an inhibitor of phosphodieasterase-4 (PDE-4), an enzyme that controls inflammation within a cell. Side effects include diarrhea, nausea and headache. These side effects may stop with continued treatment. In studies, a small number of people stopped taking Otezla because of an adverse reaction. Some participants also had unexplained weight loss. It's recommended that those taking the drug have their weight monitored regularly.
