New Phase 3 Data for TREMFYA ® ▼ (guselkumab), a First-in-Class IL-23 p19 Subunit Inhibitor, Show Consistent, High Levels of Skin Clearance Through Four Years in Adult Patients with Moderate to Severe Plaque Psoriasis


The Janssen Pharmaceutical Companies of Johnson & Johnson today announced new long-term plaque psoriasis data for TREMFYA® (guselkumab), a first-in-class treatment showing consistent, high levels of skin clearance at week 100 and week 204 (four years).1,2

In the open-label extension of VOYAGE 2, at four years, 80 percent of patients who were treated with guselkumab 100 mg every 8 weeks (q8w), achieved at least 90 percent improvement in the Psoriasis Area and Severity Index (PASI 90) score. At four years, the proportion of patients who achieved an Investigator’s Global Assessment (IGA) score of clear (0) or minimal disease (1) was 82 percent, and 51 percent of patients achieved PASI 100, or complete clearance of their psoriasis plaques.2 These data are being shared online as an accepted poster (P15300) by the American Academy of Dermatology, which conducted its annual congress virtually.2

Guselkumab is the first monoclonal antibody that selectively binds to the p19 subunit of IL-23, and inhibits its interaction with the IL-23 receptor, to have been approved by the European Commission.1

VOYAGE 2 endpoints also included patient-reported outcome measures, including the Dermatology Life Quality Index (DLQI)a and the Psoriasis Symptoms and Signs Diary (PSSD)b.3 At four years, 69 percent of patients achieved a DLQI score of 0 or 1 (indicating no impact of skin disease on health-related quality of life), 40 percent reported a PSSD symptom score of 0, and 27 percent reported a PSSD sign score of 0 (reflecting symptom- and sign-free status, respectively).2

“Psoriasis patients are often burdened by physical pain and discomfort, and providing long-term relief from the disease is also important in alleviating the related impact to patients’ quality of life,” said Kristian Reichi, M.D., Ph.D., Professor of Translational Research in Inflammatory Skin Diseases, Institute for Health Services Research in Dermatology and Nursing, University Medical Center Hamburg-Eppendorf, Germany, and lead investigator of the VOYAGE 2 study. “Results from the VOYAGE 2 study demonstrate guselkumab as an efficacious therapy through four years, providing patients who may be experiencing chronic psoriatic symptoms with a long-term treatment option.”

The safety profiles observed for guselkumab and adalimumab in VOYAGE 2 were consistent with the known safety profiles seen in the respective registration trials and current prescribing information. As in the current prescribing information, very common (>10%) and common adverse events (AEs; >1%) in controlled periods of clinical studies with guselkumab were upper respiratory infections, gastroenteritis, herpes simplex infections, tinea infections, headache, diarrhoea, urticaria, arthralgia and injection site erythema. Most were considered to be mild and did not necessitate discontinuation of study treatment.1 No new safety signals were identified at four years in the presented analyses.2

Symptom- and Sign-Free versus Adalimumab at 48 Weeks

Separately, data from the randomised, placebo-controlled, head-to-head, Phase 3 VOYAGE 1 trial comparing patient-reported outcomes between those being treated with guselkumab and those being treated with adalimumab are also being shared online as a poster (P15287). The findings show that at week 48, approximately 42 percent of guselkumab-treated patients and 23 percent of adalimumab-treated patients were symptom-free, as demonstrated by a PSSD symptom score of 0, and 36 percent vs 19 percent (both p<0.001), respectively, were sign-free, as demonstrated by a PSSD sign score of 0. Also, through week 48, patients treated with guselkumab experienced numerically more time free from symptoms like itching and pain, and signs like cracked and scaly skin, compared with patients treated with adalimumab.4

“The four-year patient-reported outcomes in the VOYAGE programme are particularly noteworthy because they show that the efficacy data for guselkumab translates into nearly 70 percent of patients reporting that their skin disease had no negative impact on their health-related quality of life and approximately 40 percent of patients reporting that they were symptom-free,” said Lloyd Miller, M.D., Ph.D., Vice President, Immunodermatology Disease Area Leader, Janssen Research & Development, LLC. “These findings are indicative of the consistent and durable skin clearance possible for adults living with moderate to severe plaque psoriasis.”

Initial four-year efficacy analyses from VOYAGE 1 were presented at the 2019 Fall Clinical Dermatology congress.5 These new data from VOYAGE 2 are consistent with and complement those findings.

Key definitions

a The Dermatology Life Quality Index is a patient questionnaire that assesses the effect of a skin disease on quality of life in ten activities of daily life over the previous week.3

b The Psoriasis Symptoms and Signs Diary is used to track the severity of five symptoms (itch, skin tightness, burning, stinging, and pain) and six signs (dryness, cracking, scaling, shedding/flaking, redness, and bleeding) of psoriasis. It is a patient-reported assessment.3

About VOYAGE 23

This Phase 3, randomised, double-blind, placebo and active comparator-controlled trial was designed to evaluate the efficacy and safety of guselkumab compared with placebo and adalimumab in adults with moderate to severe plaque psoriasis. Patients (N=992) were randomised to receive subcutaneous (SC) injections of guselkumab 100 mg (n=496) at weeks 0, 4 and every 8 weeks (q8w) thereafter; placebo (n=248) at weeks 0, 4, and 12 followed by crossover to guselkumab 100 mg at week 16; or adalimumab 80 mg (n=248) at week 0, 40 mg at week 1, then 40 mg q2w until week 23. Weeks 28–72 incorporated a randomised withdrawal study design. During the open-label period (weeks 100–204), patients received guselkumab 100 mg q8w. Physician- and patient-reported outcomes were assessed. Efficacy was analysed using pre-specified treatment failure rules beginning at week 76 (patients were considered non-responders after discontinuing due to lack of efficacy, worsening of psoriasis, or use of a prohibited treatment). Data were combined for patients randomised to guselkumab and for those originally randomised to placebo who later crossed over to guselkumab at week 16. This study will continue for a total of five years.

Efficacy assessments included proportions of patients achieving PASI 75, PASI 90 and PASI 100 responses, as well as IGA scores of 0/1 and 0, a DLQI score of 0/1, and a PSSD score of 0. Efficacy was analysed using pre-specified treatment failure rules, non-responder imputation, and as observed methodology.

About VOYAGE 16

VOYAGE 1 is a Phase 3, multicentre, randomised, double-blind, placebo- and active comparator-controlled study, with 837 patients. It included a placebo-controlled period (weeks 0–16), after which patients receiving placebo crossed over to receive guselkumab through week 48, and an active comparator-controlled period comparing guselkumab with adalimumab (week 0–48). Patients randomised to guselkumab at week 0 and those who crossed over from placebo to guselkumab at week 16 continued to receive guselkumab q8w through week 48. Beginning at week 52, all patients began receiving open-label guselkumab treatment. This study will continue for a total of five years.

VOYAGE 1 and VOYAGE 2 are part of a comprehensive guselkumab Phase 3 clinical development programme in psoriasis that includes an additional Phase 3 trial, NAVIGATE, as well as ECLIPSE, which is a Phase 3 study of guselkumab vs secukinumab.7,8

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.9 The inconsistent nature of psoriasis means that even when plaques appear to subside, patients can have ongoing concerns over their return.10


Approximately 14 million people in Europe are living with psoriasis, which often leads to a great physical and psychological burden.11 Mental health issues are common among people with psoriasis, and the impact it can have on quality of life is comparable with diabetes and cancer.12 Psoriasis is also associated with several comorbidities including psoriatic arthritis, cardiovascular diseases, metabolic syndrome, chronic obstructive pulmonary disorder (COPD) and osteoporosis.13 In addition, many individuals are faced with social exclusion, discrimination and stigma because of their disease.14

About TREMFYA®(guselkumab)1

Developed by Janssen, guselkumab is the first approved monoclonal antibody that selectively binds to the p19 subunit of interleukin (IL)-23 and inhibits its interaction with the IL-23 receptor. Guselkumab is approved as a prescription medicine in the European Union (EU), U.S., Canada, Japan and a number of other countries worldwide for the treatment of adult patients with moderate to severe plaque psoriasis who may benefit from injections or pills (systemic therapy) or phototherapy (treatment using ultraviolet [UV] light). It is approved as a prescription medicine in Japan and Brazil for the treatment of adult patients with active psoriatic arthritis. IL-23 is an important driver of the pathogenesis of inflammatory diseases such as psoriasis and psoriatic arthritis.15 Guselkumab is administered as a 100 mg SC injection once every 8 weeks, after starter doses at weeks 0 and 4 in the treatment of adults with moderate to severe plaque psoriasis.
