The Lancet Simultaneously Publishes Two Phase 3 Studies Detailing Comprehensive Efficacy and Safety of TREMFYA® (guselkumab), a First-in-Class IL-23 p19 Subunit Inhibitor, in Psoriatic Arthritis
SPRING HOUSE, Pa., April 6, 2020 /PRNewswire/ -- The Janssen Pharmaceutical Companies of Johnson & Johnson today announced that The Lancet has published comprehensive data from DISCOVER-1 and -2, two Phase 3 studies evaluating the safety and efficacy of TREMFYA(® )(guselkumab) for the treatment of adults with active psoriatic arthritis (PsA).(2,3) TREMFYA is a monoclonal antibody that selectively binds to the p19 subunit of interleukin (IL)-23 and inhibits its interaction with the IL-23 receptor. IL-23 is an important driver of the pathogenesis of inflammatory diseases such as psoriasis and PsA.(4) These are the first publications from a Phase 3 program reporting safety and efficacy results in active PsA for an antibody with this mechanism of action. TREMFYA is currently not licensed for the treatment of PsA and is undergoing evaluation for this use by the U.S. Food and Drug Administration (FDA).
Data from the two studies in the DISCOVER program formed the basis of the September 13, 2019 supplemental Biologics License Application submission to the FDA.(5 )Primary endpoint results published in The Lancet complement the first presentation of data from the DISCOVER program at the 2019 American College of Rheumatology and Association of Rheumatology Professionals Annual Meeting (ACR/ARP) in November 2019. DISCOVER-1 evaluated 381 participants with active PsA who had an inadequate response to standard therapies, including participants (~30 percent) previously treated with anti-tumor necrosis factor (TNF) alpha biologics.(2) DISCOVER-2 included 739 patients who were biologic-naïve and had an inadequate response to standard therapies.(3)
"Psoriatic arthritis is a complex disease, and patients are looking for therapies that can address as many of their distressing symptoms as possible," said lead study investigator and author of the DISCOVER-2 study, Philip J. Mease(i), M.D., Swedish Medical Center/Providence St. Joseph Health and University of Washington in Seattle, Washington. "With varied endpoints addressing joint, skin, soft tissue inflammation and physical function, plus robust safety data, these publications in The Lancet demonstrate how TREMFYA treats the multi-dimensional condition of PsA."
Results published in The Lancet show that, at week 24, the primary endpoints achieved statistical significance in both studies. Results of secondary endpoints were also reported.(2,3)
-- Joint symptoms:
-- In DISCOVER-1, among patients receiving TREMFYA 100 mg every four
weeks (q4w) and every eight weeks (q8w), 59 percent and 52 percent
achieved a 20 percent improvement in the primary endpoint of ACR
response (ACR20), respectively, vs 22 percent on placebo (both
p<0.001). In DISCOVER-2, the primary endpoint was also met; 64
percent of patients receiving TREMFYA q4w or q8w achieved an ACR20
response, vs 33 percent on placebo (both p<0.0001).
-- In DISCOVER-1, 37 percent of TREMFYA q4w and 30 percent of TREMFYA
q8w patients achieved an ACR50 improvement, vs 9 percent on placebo
(both p<0.0001). In DISCOVER-2, 33 percent of TREMFYA q4w and 31
percent of TREMFYA q8w patients achieved the same endpoint at week
24, vs 14 percent on placebo (both p<0.0001). Higher proportions of
patients receiving TREMFYA q4w or q8w also attained an ACR70
response at week 24 vs the placebo groups.
-- In DISCOVER-2, where the impact of TREMFYA on inhibition of
radiographic damage progression was studied, TREMFYA q4w
demonstrated statistically significant inhibition of radiographic
progression of joint structural damage as measured by mean
improvement from baseline in van der Heijde score (p=0.011).(6
)TREMFYA q8w demonstrated numerical but not statistically
significant inhibition of structural damage compared to placebo at
week 24 (p=0.072).
-- Skin:
-- Among patients who had clinically relevant psoriasis at baseline in
DISCOVER-1, 75 percent receiving TREMFYA q4w and 57 percent
receiving TREMFYA q8w achieved clear or almost clear skin at week
24(7), vs 15 percent on placebo (both p<0.0001). In DISCOVER-2, 68
percent of patients receiving TREMFYA q4w and 70 percent receiving
TREMFYA q8w achieved the same endpoint at week 24, vs 19 percent on
placebo (both p<0.0001).
-- Higher Psoriasis Area and Severity Index (PASI) 75, PASI 90, PASI
100 response rates were observed in the TREMFYA groups vs the
placebo groups at week 24 (in DISCOVER-1, all unadjusted p<0.0001
with PASI 100 being p=0.0005 and in DISCOVER-2, all unadjusted
p<0.0001).
-- Soft tissue inflammation and composite measures of disease activity:
-- Based on analysis of pooled data from DISCOVER-1 and -2, among
patients who had enthesitis (pain where the bone, tendon and
ligament meet) at baseline, enthesitis resolved in 45 percent of
TREMFYA q4w and 50 percent of TREMFYA q8w patients, vs 29 percent on
placebo (both p=0.0301).(8)
-- Based on analysis of pooled data from DISCOVER-1 and -2, among
patients who had dactylitis (severe inflammation of the finger and
toe joints) at baseline, dactylitis resolved in 64 percent of
TREMFYA q4w patients and 59 percent of q8w patients, vs 42 percent
on placebo (p=0.011 and p=0.0301, respectively).(9)
-- In DISCOVER-1, 30 percent of TREMFYA q4w and 23 percent of TREMFYA
q8w patients were considered to have achieved minimal disease
activity, vs 11 percent on placebo (p=0.0002 and p=0.012,
respectively). In DISCOVER-2, 19 percent of TREMFYA q4w patients and
25 percent of TREMFYA q8w patients achieved the same endpoint, vs 6
percent on placebo (both p<0.0001).(10)
-- Patient-reported outcome measures assessing physical function and
health-related quality of life:
-- TREMFYA patients reported clinically meaningful mean improvements in
Health Assessment Questionnaire Disability Index (HAQ-DI)(11) (all
p<0.0001) and the 36-Item Short-Form Health Survey (SF-36)(12)
Physical Component Summary score (PCS)(13), which measures
patient-reported functional health and well-being from baseline (in
DISCOVER-1, both p<0.0001, and in DISCOVER-2 both p=0.011).
Improvements from baseline that did not reach statistical
significance versus placebo (all p>0.05) were reported in SF-36
Mental Component Summary score (MCS), which measures
patient-reported mental well-being.
-- Safety:
-- In DISCOVER-1 and -2, serious adverse events up to week 24 in q4w (0
and 3 percent) and q8w (3 and 1 percent) were similar to those in
the placebo (4 and 3 percent).
-- Observed adverse events (AEs) were generally consistent with
previous studies of TREMFYA and current prescribing information. In
DISCOVER-1, 55 percent of patients receiving TREMFYA q4w, 54 percent
of patients receiving TREMFYA q8w, and 60 percent of patients
receiving placebo reported AEs up to week 24. In DISCOVER-2, AEs
were reported by 46 percent of patients receiving TREMFYA q4w, 46
percent of patients receiving TREMFYA q8w, and 41 percent of
patients in the placebo groups.
-- No opportunistic infections and cases of new inflammatory bowel
disease were observed in patients treated with TREMFYA.
-- No new safety signals were reported.
"The IL-23 immune pathway is associated with a number of immune-mediated inflammatory diseases, including psoriasis and psoriatic arthritis," said Alyssa Johnsen, M.D., Ph.D., Vice President, Rheumatology Disease Area Leader, Janssen Research & Development, LLC. "We're excited to share the DISCOVER-1 and -2 data in psoriatic arthritis, a disease that is a concern for so many who are also grappling with psoriasis, where TREMFYA has already made an impact."
TREMFYA was first approved by the FDA on July 13, 2017 for the treatment of adults with moderate to severe plaque psoriasis who are candidates for systemic therapy or phototherapy.(14 )It is currently approved in 72 countries for this indication.
About DISCOVER-1 (NCT03162796)(15
)DISCOVER-1 was a randomized, double-blind, multicenter Phase 3 study evaluating the efficacy and safety of TREMFYA administered by subcutaneous (SC) injection in participants with active PsA, including those previously treated with anti-TNF therapies. DISCOVER-1 evaluated 381 participants and ended after approximately one year.
The study consisted of: a screening phase of up to six 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, and a safety follow-up phase of eight 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)(16
)DISCOVER-2 is a randomized, double-blind, multicenter Phase 3 study evaluating the efficacy and safety of TREMFYA administered by SC injection in biologic-naïve participants with active PsA. DISCOVER-2 is evaluating 739 participants and continuing through approximately two years.
The study consists of: a screening phase of up to six 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 PsA
PsA is a chronic, immune-mediated inflammatory disease characterized by peripheral joint inflammation, enthesitis, dactylitis, axial disease, and the skin lesions associated with psoriasis.(17) Studies show that up to 30 percent of people with psoriasis also develop PsA.(1) The disease causes pain, stiffness and swelling in and around the joints; it commonly appears between the ages of 30-50, but can develop at any time.1 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)(14
)Developed by Janssen, TREMFYA is the first marketed monoclonal antibody that selectively binds to the p19 subunit of IL-23 and inhibits its interaction with the IL-23 receptor. It is approved as a prescription medicine in the U.S., Canada, the EU, 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). IL-23 is an important driver of the pathogenesis of inflammatory diseases such as psoriasis and psoriatic arthritis.(4) In psoriasis, TREMFYA is administered as a 100 mg SC injection once every 8 weeks, after starter doses at weeks 0 and 4.
