MADRID --(BUSINESS WIRE)-- 13.06.2019 --
The Janssen Pharmaceutical Companies of Johnson & Johnson presented new data this week from PsABio - its ongoing, real-world study of nearly 1,000 people with psoriatic arthritis, who have started treatment with either Stelara (ustekinumab) or a Tumour Necrosis Factor inhibitor (TNFi).1 This important data was presented at this year's Annual European Congress of Rheumatology (EULAR 2019) in Madrid, Spain.
PsA is a challenging and multi-faceted immune-mediated inflammatory disease affecting multiple sites in the body, for example, the skin, joints and soft tissue. Furthermore, co-morbidities such as obesity, cardiovascular disease and metabolic syndrome, are often associated with PsA.2
The PsABio study is investigating the impact of achieving low disease activity in the key characteristics of PsA i.e. skin and joint inflammation.3 The results presented from the analysis showed that treatment with either ustekinumab or TNFi's leads to considerable and comparable numbers of patients reaching low disease activity (LDA) or remission, after six months of treatment.3 Furthermore, these outcomes were shown to be associated with improved health-related quality of life (HRQoL), better physical functioning and reduced pain.3,4
"The many disease manifestations caused by PsA profoundly affect patients' quality of life, ability to function and experience of pain. For their burden of disease to be reduced, treatment strategies should address all these disease symptoms," commented Laure Gossec, Primary Investigator of the PsABio study and Professor of Rheumatology at Pitie-Salpétriere Hospital and Sorbonne Université, Paris, France. She continued, "Our data therefore support a treat-to-target strategy in routine care of PsA to ensure patients achieve remission or low-disease activity and an improved health-related quality of life."
Beyond skin and joints, PsA patients are often affected by co-morbidities such as obesity.2 A further analysis from PsABio looked at the impact of obesity on PsA disease activity at study baseline.5 This relationship was investigated in 917 patients with PsA taking either ustekinumab or TNFi.5 Results demonstrated that obesity was linked to a high disease activity at baseline in terms of physician-reported and patient-reported outcomes, level of skin involvement (body surface area) and physical function (HAQ) outcomes and more severe disease activity.5 In a multivariate analysis, higher BMI was independently linked to higher PsA disease activity, disease impact and impaired functioning. As obesity is common in patients with PsA, these results highlight the need for lifestyle-directed approaches in treating PsA, such as weight management in parallel with joint- and skin-focused treatment.2,5
The common (≥1/100) adverse reactions reported in controlled periods of the adult psoriasis, psoriatic arthritis and Crohn's disease clinical studies with ustekinumab as well as post-marketing experience were: upper respiratory tract infection, arthralgia, back pain, diarrhoea, dizziness, fatigue, headache, infection site pain, injection site erythema, myalgia, nasopharyngitis, nausea, oropharyngeal pain, pruritus and vomiting.10
"At Janssen, we understand the value of providing 'real-world' data to the medical community and we are pleased that the PsABio study will help to answer some important questions regarding the optimal management of people with PsA in everyday clinical practice," commented Dr Jaime Oliver, Therapeutic Area Lead, Immunology and CVT, Europe Middle East & Africa, Janssen Cilag GmbH International. "As the PsABio study continues to gather more real-world data, we will share further insights to help improve the lives of patients with PsA."
It is estimated that up to 42 percent of the 14 million people who are living with psoriasis in Europe will also develop psoriatic arthritis which causes pain, stiffness and swelling in and around the joints.6,7
About the PsABio Study
The PsABio study (NCT no. NCT02627768 / CNTO1275PSA4003) is an on-going, prospective, observational, cohort study, being conducted in 8 European countries, assessing the efficacy, tolerability and persistence of ustekinumab and TNFi for patients with PsA starting 1st, 2nd or 3rd line biologic disease-modifying antirheumatic drugs (bDMARDs) in real-world routine care.1
In the Gossec et al. abstract showing LDA analysis and the 'treat-to-target' strategy, of the 563 ustekinumab or TNFi-treated patients enrolled between Dec 2015-Aug 2017, 303 had data available from their 6-month follow-up.3 Disease states were defined using the Clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA) ≤4 for remission and ≤13 for LDA (data available for 250 patients) and VLDA (Very Low Disease Activity) 7/7 and minimal disease activity (MDA) 5/7 criteria (data available for 206 and 260 patients, respectively).3 HRQoL was assessed by the generic instrument, EQ5D, and the PsA specific tool, PsAID-12. Physical functioning was measured by the Health Assessment Questionnaire without Disability Index (HAQ-DI) and pain measured with a Pain VAS (Visual Analog Scale) (0-100).3 Assessment of Psoriasis Skin Disease (68/299=22.7%) was the most frequently missed MDA component, while enthesitis was the least frequently missed (6/299=2.0%).3 The other 5 components were all missed with equal frequency (8-9%). Available observed data on univariate associations were presented, with no imputation of missing data or adjustment for baseline imbalances.3
For the 303 patients, mean age was 49.7 (standard deviation [SD] 12.8) years, mean disease duration was 7.2 (SD, 8.2) years, and 50.5% were women.3 Results at 6 months showed approximately equal rates of cDAPSA remission, cDAPSA LDA, MDA and VLDA with both ustekinumab and TNFi's. cDAPSA remission/LDA and VLDA/MDA achievement in both treatment groups was associated with improved general and disease-specific health-related quality of life (HRQoL) assessments (EQ5D VAS, PsAID-12), physical functioning (HAQ-DI) and pain (VAS).3,4
A second analysis reported by Siebert et al. investigated the relationship between baseline overweight/obesity and disease activity, patient-reported outcomes and disability in a large real-world cohort of patients with PsA starting biologic treatment with either ustekinumab or TNFi.5 Baseline data of the study population were collected and analysed for body mass index (BMI), disease activity (cDAPSA, psoriasis, BSA), patient-perceived impact (PsAID-12), disability (HAQ-DI) and presence or history of CVD/MET (cardiovascular disease/metabolic equivalent).5 Descriptive statistics of available data and three exploratory multiple regression models were described, to investigate the relationship of cDAPSA, PsAID-12 and HAQ-DI (dependent variables) with BMI, adjusted for age, sex, smoking, body surface area, c-reactive protein, disease duration and biologic treatment.5
About psoriatic arthritis
Psoriatic arthritis is a chronic, immune-mediated inflammatory disease characterised by both joint inflammation and the skin lesions associated with psoriasis.8 The disease causes pain, stiffness and swelling in and around the joints and commonly appears between the ages of 30 and 50, but can develop at any time.9 Although the exact cause of psoriatic arthritis is unknown, genes, the immune system and environmental factors are all believed to play a role in disease onset.9
In the European Union, ustekinumab is approved for the treatment of moderate to severe plaque psoriasis in adults who failed to respond to, or who have a contraindication to, or are intolerant to other systemic therapies including ciclosporin, methotrexate or psoralen plus ultraviolet A (PUVA), and is also indicated for the treatment of moderate to severe plaque psoriasis in adolescent patients from the age of 12 years and older who are inadequately controlled by or are intolerant to other systemic therapies or phototherapies. In addition, ustekinumab is approved alone or in combination with MTX for the treatment of active psoriatic arthritis in adult patients when the response to previous non-biological disease-modifying antirheumatic drug (DMARD) therapy has been inadequate. Ustekinumab is approved by the European Commission for the treatment of adult patients with moderately to severely active Crohn's disease who have had an inadequate response with, lost response to, or were intolerant to either conventional therapy or a TNF-alpha antagonist or have medical contraindications to such therapies.
The common (≥1/100) adverse reactions reported in controlled periods of the adult psoriasis, psoriatic arthritis and Crohn's disease clinical studies with ustekinumab as well as post-marketing experience were: upper respiratory tract infection, arthralgia, back pain, diarrhoea, dizziness, fatigue, headache, infection site pain, injection site erythema, myalgia, nasopharyngitis, nausea, oropharyngeal pain, pruritus and vomiting.
The Janssen Pharmaceutical Companies of Johnson & Johnson maintain exclusive worldwide marketing rights to ustekinumab, which is currently approved for the treatment of moderate to severe plaque psoriasis in 89 countries, paediatric psoriasis in 44 countries, psoriatic arthritis in 83 countries and Crohn's disease in 70 countries.
