DRUG TRIALS SNAPSHOT SUMMARY:
What is the drug for?
TREMFYA is a drug for treatment of moderate to severe plaque psoriasis in adults who may benefit from taking injections or pills (systemic therapy) or phototherapy (treatment using ultraviolet or UV light).
How is this drug used?
TREMFYA is an injection given under the skin. First two injections are given 4 weeks apart followed by an injection once every eight weeks.
What are the benefits of this drug (results of trials used to assess efficacy)?
TREMFYA was better than a placebo in improving symptoms of plaque psoriasis and maintaining the improvement through a year of treatment.
Were there any differences in how well the drug worked in clinical trials among sex, race and age?
- Sex: TREMYFA worked similarly in men and women.
- Race: The majority of patients were White. The number of patients in other races was limited; therefore, differences in response among races could not be determined.
- Age: The number of patients above 65 years of age was limited; therefore, differences in response between patients above and below 65 years of age could not be determined.
What are the possible side effects?
TREMFYA may cause serious infections. Before starting TREMFYA, patients should be evaluated for tuberculosis infection.
The most common side effects of TREMFYA are upper respiratory tract infections, headache, injection site reactions, joint pain, diarrhea, stomach flu, fungal skin infections and herpes simplex infections.
Were there any differences in side effects among sex, race and age?
- Sex: The risk of side effects was similar in men and women.
- Race: The majority of patients were White. The number of patients in other races was limited; therefore, differences in side effects among races could not be determined.
- Age: The majority of patients were below 65 years of age. The difference in side effects between patients below and above age 65 years could not be determined.
WHO WAS IN THE STUDIES?
Who participated in the clinical trials?
The FDA approved TREMYFA based on evidence from two clinical trials of 1829 patients with moderate to severe psoriasis. The trials were conducted in the USA, Canada, Europe, Russia, Australia, Korea, and Taiwan.
The figure below summarizes how many men and women were enrolled in the clinical trials.

FDA Review
How were the trials designed?
The benefit and side effects of TREMFYA were evaluated in two clinical trials of patients with moderate to severe psoriasis. Patients received one of the three treatments: TREMFYA, placebo or drug approved for psoriasis called adalimumab. Neither the patients nor the health care providers knew which treatment was being given until after the benefit was evaluated.
Patients were evaluated for improvement of psoriasis after 16 weeks of treatment by scoring of the extent, nature and severity of psoriatic changes of the skin. Some patients who achieved success with TREMFYA at Week 16 continued the treatment for 12 months to determine how long the benefit would last.
GLOSSARY
CLINICAL TRIAL: Voluntary research studies conducted in people and designed to answer specific questions about the safety or effectiveness of drugs, vaccines, other therapies, or new ways of using existing treatments.
COMPARATOR: A previously available treatment or placebo used in clinical trials that is compared to the actual drug being tested.
EFFICACY: How well the drug achieves the desired response when it is taken as described in a controlled clinical setting, such as during a clinical trial.
PLACEBO: An inactive substance or “sugar pill” that looks the same as, and is given the same way as, an active drug or treatment being tested. The effects of the active drug or treatment are compared to the effects of the placebo.
SUBGROUP: A subset of the population studied in a clinical trial. Demographic subsets include sex, race, and age groups.
