European Commission Authorises Janssen’s TREMFYA^®▼ (guselkumab), a First-in-Class Treatment for Active Psoriatic Arthritis (PsA)

 

Guselkumab is the first selective IL-23 p19 subunit inhibitor licensed for both the treatment of PsA and plaque psoriasis

 

High Wycombe, UK, 01 December, 2020 – The Janssen Pharmaceutical Companies of Johnson & Johnson announced today that the European Commission (EC) has granted marketing authorisation for TREMFYA^®▼ (guselkumab) alone or in combination with methotrexate (MTX) for the treatment of active psoriatic arthritis (PsA) in adult patients who have had an inadequate response or who have been intolerant to a prior disease-modifying antirheumatic drug (DMARD) therapy.

 

Guselkumab is the first licensed fully human monoclonal antibody that selectively binds to the p19 subunit of interleukin (IL)-23 and inhibits its interaction with the IL-23 receptor. It is already licensed for the treatment of patients with moderate to severe plaque psoriasis who are candidates for systemic therapy.[1] IL-23 is an important driver of the progression of inflammatory diseases including psoriasis and PsA.[2]

 

PsA is a multifaceted, chronic, immune-mediated inflammatory disease that is progressive and is characterised by debilitating joint damage and inflammation, in addition to enthesitis, dactylitis, and the skin lesions associated with psoriasis.[3] The pain, stiffness and swelling of the joints and connective tissue can be severe and cause everyday tasks to become difficult.^3,[4] In addition, more than half of people with PsA also live with another condition, such as cardiovascular disease, osteoporosis, inflammatory bowel disease or depression.[5]^,[6] There is currently no known cure for PsA, and it is estimated that up to 123,000 people in the UK are living with PsA and up to 30 percent of those living with psoriasis may also develop PsA.[7]^,[8]

 

“Psoriatic arthritis can have a highly detrimental impact on those living with this chronic, inflammatory condition. Symptoms are often debilitating, leading to irreversible joint damage in some, and preventing a majority of people getting on with day-to-day life and work” commented Professor Iain McInnes, Muirhead Chair of Medicine and Vice Principal & Head of College of Medical, Veterinary and Life Sciences, University of Glasgow*. “There remains a need for additional effective treatment options that improve joint and skin symptoms, and overall quality of life. I welcome the authorisation of guselkumab as a new biologic treatment option for adults with psoriatic arthritis.”

 

Authorisation for this new indication is based on results from the DISCOVER-1 and DISCOVER-2 Phase 3 clinical studies, which assessed the efficacy and safety profile of guselkumab 100 mg every 4 weeks (q4w) and every 8 weeks (q8w) in adult patients with active PsA. DISCOVER-1 evaluated 381 participants with active PsA who had an inadequate response to standard therapies, including participants (~30 percent) previously treated with anti-tumour necrosis factor (TNF) alpha biologics.[9] DISCOVER-2 included 739 patients who were biologic-naïve only and had an inadequate response to standard therapies.[10] Data from these studies was published earlier this year in The Lancet (24-weeks; DISCOVER-1, DISCOVER 2).^9,10

 

• The published results show that in both studies, at week 24, adult patients with active PsA achieved statistical significance in the primary endpoint of American College of Rheumatology (ACR) 20 percent improvement (ACR20) response (DISCOVER-1: p<0.0001; DISCOVER-2: p<0.0001) in both q4w and q8w guselkumab groups (DISCOVER-1: n=255; DISCOVER-2: n=493) vs the placebo groups (DISCOVER-1: n=126; DISCOVER-2: n= 246).^9,10
• In addition, significant improvements in quality of life scores (36-item short-form [SF36] physical component summary) were observed in the guselkumab groups vs the placebo groups in DISCOVER-1 (p<0.0001 for both doses); in DISCOVER-2, significant improvements were observed in the q4w guselkumab group vs placebo group (p=0.0056).^9,10
• In DISCOVER 2, inhibition of structural damage progression was measured radiographically and expressed as the mean change from baseline in the total PsA-modified van der Heijde-Sharp (vdH-S) score. At Week 24, the guselkumab q4w group demonstrated statistically significantly less radiographic progression (p=0.0056) and the guselkumab q8w group showed numerically less progression than placebo (p =0.07).^10,[11]
• In addition, higher Psoriasis Area and Severity Index 75 percent improvement (PASI 75), PASI 90 and PASI 100 response rates were observed in the q4w and q8w guselkumab groups vs the placebo groups (in DISCOVER-1, all unadjusted p<0.0001 with PASI 100 being p=0.0005 and in DISCOVER-2, all unadjusted p<0.0001).^9,10

 

In both studies, guselkumab was generally well-tolerated, and observed adverse events (AEs) were generally consistent with previous studies of guselkumab and current prescribing information. In DISCOVER-1 and -2, serious adverse events up to week 24 in q4w treatment arms (0 and 3 percent) and q8w treatment arms (3 and 1 percent) were similar to those in the placebo arms (4 and 3 percent). In DISCOVER-2, less than 1 percent of patients experienced serious infections following guselkumab treatment, and no patient experienced serious infections following guselkumab treatment in DISCOVER-1. There were no reported deaths in guselkumab-treated patients and no guselkumab-treated patient had inflammatory bowel disease, opportunistic infections such as tinea or candida, active tuberculosis or anaphylactic or serum sickness-like reactions. ^9,10 Very common (≥10 percent) and common AEs (≥1 percent) in controlled periods of clinical studies with guselkumab were respiratory tract infections, increased transaminases, headache, diarrhoea, arthralgia and injection site reactions.¹

 

“Guselkumab represents a new treatment option – the first in its class – for patients with psoriatic arthritis, in an area where additional treatment options are needed. The DISCOVER 1 and 2 studies, which this authorisation is based on, show the potential of guselkumab to improve skin and joint symptoms including structural joint damage, which are all important elements of sustained management of psoriatic arthritis,” said David M. Lee, M.D., Ph.D., Global Therapeutic Area Head, Immunology, Janssen Research & Development, LLC. “Today’s authorisation marks an exciting breakthrough as we continue to reimagine what is possible in how immune-mediated diseases like active PsA are understood and treated.”

 

This marketing authorisation follows a positive opinion from the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA), issued on 15 October.

About DISCOVER-1 (NCT03162796; EudraCT 2016-001163-37)[12]^,[13]

DISCOVER-1 was a randomised, double-blind, multicentre Phase 3 study evaluating the efficacy and safety of guselkumab 100 mg q4w and q8w administered by subcutaneous (SC) injection in participants with active psoriatic arthritis PsA including those previously treated with biologic anti-TNF therapies. DISCOVER-1 evaluated 381 participants, continuing through approximately 1 year.⁹

 

 

The study consisted of a screening phase of up to 6 weeks, a blinded treatment phase of 52 weeks that included a placebo-controlled period from week 0 to week 24 and an active treatment period from week 24 to week 52. It also included a safety follow-up phase of 8 weeks after week 52 (week 52 to 60; 12 weeks from the last administration of study agent [at week 48] through to the final visit in the safety follow-up phase). Efficacy, safety, pharmacokinetic, immunogenicity and biomarker evaluations were performed in the study on a defined schedule.

 

About DISCOVER-2 (NCT03158285; EudraCT 2016-001224-63)[14]^,[15]

DISCOVER-2 is a randomised, double-blind, multicentre Phase 3 study evaluating the efficacy and safety of guselkumab 100 mg q4w and q8w administered by SC injection in participants with active PsA. DISCOVER-2 is evaluating 739 participants and continuing through approximately 2 years.

 

The study consists of a screening phase of up to 6 weeks, a blinded treatment phase (approximately 100 weeks) that includes a placebo-controlled period from week 0 to week 24 and an active treatment period from week 24 to week 100, and a safety follow-up phase of 12 weeks after the last administration of study agent. Efficacy, health economics, safety, pharmacokinetics, immunogenicity, biomarker and pharmacogenomics evaluations are being performed in the study on a defined schedule.

 

About Psoriatic Arthritis

Psoriatic arthritis (PsA) is a chronic, immune-mediated inflammatory disease characterized by peripheral joint inflammation, enthesitis (pain where the bone, tendon and ligament meet), dactylitis (severe inflammation of the finger and toe joints), and the skin lesions associated with psoriasis.^3,[16]^,[17] In addition, in patients with PsA, comorbidities such as obesity, cardiovascular diseases, anxiety and depression are often present.⁶ It is estimated that up to 123,000 people in the UK are living with PsA and up to 30 percent of those with psoriasis may also develop PsA.^7,8 The disease causes pain, stiffness and swelling in and around the joints; it commonly appears between the ages of 30 and 50, but can develop at any time.[18] Though the exact cause of PsA is unknown, genes, the immune system and environmental factors are all believed to play a role in the onset of the disease.¹⁸

 

About TREMFYA^® (guselkumab)¹

Developed by Janssen, guselkumab is the first licensed monoclonal antibody that selectively binds to the p19 subunit of IL-23 and inhibits its interaction with the IL-23 receptor. Guselkumab is licensed as a prescription medicine in the EU, US, 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). In addition to this EU authorisation, it is also licensed in the US, Canada, Japan, Brazil, Ecuador and Taiwan for the treatment of adult patients with active PsA. IL-23 is an important driver of the pathogenesis of inflammatory immune-mediated diseases such as psoriasis and PsA.² In the EU, guselkumab is administered as a 100 mg SC injection once every 8 weeks, after starter doses at weeks 0 and 4 for both plaque psoriasis and PsA, with 100 mg SC doses every 4 weeks considered in patients with PsA who are at high risk for joint damage according to clinical judgement.
