European Commission Approves TREMFYAR (guselkumab) for the Treatment of Moderate to Severe Plaque Psoriasis in the European Union


Janssen’s guselkumab is the first biologic to be approved that selectively blocks interleukin (IL)-23

Janssen-Cilag International NV announced today that the European Commission (EC) has approved TREMFYAR (guselkumab) for the treatment of adults with moderate to severe plaque psoriasis who are candidates for systemic therapy.[1] Guselkumab is the first biologic that selectively blocks interleukin (IL)-23, a key driver of the immune inflammatory response in psoriasis.[2],[3],[4],[5]

“We are delighted guselkumab will now be available to patients in Europe,” said Kris Sterkens, Company Group Chairman, Janssen Europe, Middle East and Africa (EMEA). “With 14 million people in the region affected by this often painful and potentially disabling disease, we must continue the fight to help improve the lives of those affected. We are proud to be introducing an innovative new option to help address the continued needs of people living with plaque psoriasis.”

Guselkumab is a self-injectable (following training) treatment for psoriasis. Treatment requires two starter doses, one initially and the other four weeks later, followed by a maintenance dose once every eight weeks (q8w) thereafter.[3],[4]

The EC approval is based on data from three Phase III clinical studies. The VOYAGE 1 and 2 trials, which compared guselkumab with placebo and HUMIRAR (adalimumab), showed high levels of skin clearance after just 16 weeks, with at least a 90% reduction in Psoriasis Area and Severity Index score (PASI 90) in 73.3% and 70.0% of patients receiving guselkumab, compared with 49.7% and 46.8% in patients receiving adalimumab, respectively (P[2],[3]

The NAVIGATE trial evaluated patients who did not achieve a response of cleared or minimal disease (Investigator’s Global Assessment [IGA] score of 0 or 1) by week 16 when treated with STELARAR (ustekinumab), and were then randomised to either switch to guselkumab or continue on ustekinumab.[4] The guselkumab group benefited significantly from the switch, with a significantly higher mean number of visits at which patients achieved an IGA score of 0 or 1 and at least a 2-grade improvement from week 28 through week 40 (relative to week 16), compared to the ustekinumab group (1.5 vs 0.7; P[4]

During the clinical development programme for guselkumab in psoriasis there were no clear signals of increased risk of malignancy, major cardiovascular events or serious infections, including tuberculosis and the re-activation of latent tuberculosis.[2],[3],[4] Adverse events reported in at least 5% of guselkumab-treated patients during the first 16 weeks in the VOYAGE 1 and 2 trials included: nasopharyngitis, upper respiratory tract infection, injection site erythema, headache, arthralgia, pruritus and back pain. The types of adverse events reported remained generally consistent through 48 weeks of treatment.[2],[3]

Marketing authorisation follows a positive opinion from the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA), issued on 14 September 2017.[6] This approval allows for the marketing of TREMFYAR (guselkumab) in all 28 member states of the European Union as well as the European Economic Area countries (Norway, Iceland and Liechtenstein). Janssen received US FDA approval of guselkumab for the treatment of adults with moderate to severe plaque psoriasis who are candidates for systemic therapy or phototherapy in July 2017.[7]

About guselkumab


Lifecycle development

Phase III studies are being undertaken to evaluate the efficacy and safety of guselkumab for patients with psoriatic arthritis.[9] A Phase III comparator study (the ECLIPSE study) is underway to evaluate the efficacy of guselkumab versus CosentyxR (secukinumab), an IL-17A inhibitor, in patients with moderate to severe plaque psoriasis.[10]

About Psoriasis

What it is

The most common form of psoriasis is plaque psoriasis, usually resulting in areas of thick, red or inflamed skin covered with silvery scales which are known as plaques.[11] The inconsistent nature of psoriasis means that even when plaques appear to subside, many patients still live in fear of their return.[12]


Psoriasis can cause great physical and psychological burden. A study comparing psoriasis to other prominent conditions found its mental and physical impact comparable to that seen in cancer, heart disease and depression.[13]

Psoriasis is also associated with several comorbidities including psoriatic arthritis, cardiovascular diseases, metabolic syndrome, chronic obstructive pulmonary disorder (COPD) and osteoporosis.[14],[15]

In addition, many individuals are faced with social exclusion, discrimination, and stigma because of their disease.[16]
