Positive Trial Results with Filgotinib in Psoriatic Arthritis and Ankylosing Spondylitis Both Published in The Lancet
-- Phase 2 EQUATOR Data Demonstrating Efficacy in Psoriatic Arthritis Also Presented in a Plenary Session at 2018 ACR/ARHP Annual Meeting --
“The results of the EQUATOR and TORTUGA studies demonstrate that
filgotinib improved the signs and symptoms of patients with psoriatic
arthritis whose disease had not responded to prior therapies and
independently, for those with ankylosing spondylitis,” said
“We are pleased that filgotinib demonstrates a consistent safety and
efficacy profile across multiple inflammatory conditions, including
psoriatic arthritis and ankylosing spondylitis,” said Dr.
Phase 2 EQUATOR Study in Psoriatic Arthritis [ACR/ARHP Abstract #1821]
Data from EQUATOR, a placebo-controlled trial of 131 adults with
moderately to severely active psoriatic arthritis who had an inadequate
response or were intolerant to at least one conventional
disease-modifying anti-rheumatic drug (cDMARD), demonstrated the
efficacy of filgotinib in this patient population. The study achieved
its primary endpoint at Week 16, with 80 percent of patients on
filgotinib 200mg once-daily achieving ACR20, compared with 33 percent on
placebo (p<0.001). ACR50 and ACR70 responses at Week 16 were also
significantly higher for filgotinib compared with placebo (ACR50: 48
percent for filgotinib vs 15 percent for placebo, p<0.001; ACR70: 23
percent vs 6 percent, p<0.01). These data were previously announced in
The study also found greater improvement in disease signs and symptoms for patients receiving filgotinib 200mg once-daily compared with placebo at Week 16, as measured by Minimal Disease Activity (MDA) (23 percent vs 9 percent, p<0.05) and the Psoriasis Area and Severity Index 75 percent improvement from baseline (PASI75) (45 percent vs 15 percent, p<0.01). The data showed greater improvement from baseline in the Health Assessment Questionnaire Disability Index (HAQ-DI) for those receiving filgotinib compared with placebo (-0.57 vs -0.28, p<0.001).
Safety-related outcomes were similar between the filgotinib and placebo arms of the study, including rates of treatment-emergent adverse events (57 percent and 59 percent, respectively) and infections and infestations (22 percent and 21 percent). Two serious treatment-emergent adverse events were reported: one hip fracture in the placebo group and one case of fatal pneumonia in the filgotinib treatment group, which was the only serious infection and the only death in the study. No deep venous thrombosis, pulmonary embolism, malignancies, gastrointestinal perforations, opportunistic infections/active tuberculosis or cases of Herpes zoster were reported.
“Effective treatment for psoriatic arthritis is critical for relieving
pain and inflammation and helping to prevent joint damage.
Unfortunately, not all patients respond to currently available
Phase 2 TORTUGA Study in Ankylosing Spondylitis
In the Phase 2 TORTUGA study, adults with moderately to severely active ankylosing spondylitis who were treated with filgotinib 200mg once-daily achieved significantly greater improvements in AS Disease Activity Score (ASDAS), the primary endpoint, at Week 12. The mean change from baseline in ASDAS was -1.5 for patients treated with filgotinib versus -0.6 for those treated with placebo (p<0.0001). ASAS20 and ASAS40 responses at Week 12 were also significantly higher for filgotinib compared with placebo (ASAS20: 76 percent for filgotinib vs 40 percent for placebo, p<0.0001; ASAS40: 38 percent vs 19 percent, p<0.05).
Adverse events were generally mild or moderate in severity and were reported in an equal proportion of patients in the filgotinib and placebo groups (31 percent). Laboratory changes were consistent with those previously reported for filgotinib, and no new safety signals were observed in the study. There was one treatment-emergent serious adverse event of pneumonia reported for a patient receiving filgotinib who recovered after hospital-based antibiotic treatment. One patient with an inherited risk for thrombosis who was randomized to filgotinib experienced a non-serious deep venous thrombosis after completing the course of study drug. No deaths, malignancies, hepatic events, gastrointestinal perforations, opportunistic infections/active tuberculosis, or cases of Herpes zoster were reported.

About the EQUATOR Trial
Initiated by Galapagos in
The primary objective of EQUATOR was to evaluate the effect of filgotinib compared to placebo on the signs and symptoms of psoriatic arthritis, as assessed by the proportion of patients achieving ACR20 at Week 16. Secondary objectives included the proportion of patients achieving ACR50/70 and MDA as well as the effects of filgotinib on psoriasis, dactylitis (whole finger inflammation) and enthesitis (inflammation of the tendons).
About the TORTUGA Study
TORTUGA was a multi-center, randomized, double-blind, placebo-controlled, Phase 2 study to assess the safety and efficacy of filgotinib in adult patients with moderately to severely active AS. The trial was conducted in Belgium, Bulgaria, Czech Republic, Estonia, Poland, Spain and Ukraine. In total, 116 patients were randomized in a 1:1 ratio to receive filgotinib 200 mg or placebo once daily for 12 weeks.
The primary objective of TORTUGA was to evaluate the effect of filgotinib compared to placebo on the signs and symptoms of AS, as assessed at Week 12 by ASDAS (a standard composite index for assessing the disease, which incorporates five disease activity variables).
