Efficacy and safety of filgotinib in methotrexate-naive patients with rheumatoid arthritis with poor prognostic factors: post hoc analysis of FINCH 3.

ABSTRACT:

Objective

This analysis evaluated efficacy and safety of filgotinib, a Janus-associated kinase 1-preferential inhibitor, in methotrexate (MTX)-naive patients with rheumatoid arthritis (RA) with multiple poor prognostic factors (PPFs).

Methods

This was a post hoc analysis of the phase III, randomised, double-blind, active-controlled, FINCH 3 study (clinicaltrials.gov NCT02886728). Patients received once-daily oral filgotinib 200 or 100 mg plus once-weekly oral MTX ≤20 mg (FIL200 + MTX and FIL100 + MTX), filgotinib 200 mg monotherapy (FIL200), or oral MTX monotherapy (MTX-mono) for up to 52 weeks. PPFs investigated were seropositivity for rheumatoid factor or anticyclic citrullinated peptide antibodies, high-sensitivity C reactive protein (CRP) ≥4 mg/L, Disease Activity Score in 28 joints with CRP (DAS28(CRP)) >5.1, and presence of erosions. Filgotinib efficacy and safety in patients with all four PPFs at baseline were explored versus MTX-mono within this subgroup and compared informally with the overall population.

Results

Of 1249 patients in FINCH 3, 510 (40.8%) had all PPFs. Efficacy of FIL200 + MTX among these patients was comparable to the overall population, with higher rates of 20%/50%/70% improvement from baseline by American College of Rheumatology criteria, DAS28(CRP) <2.6, and remission; greater improvement in physical function and pain; and better inhibition of structural damage relative to MTX-mono. FIL100 + MTX and FIL200 were not consistently more efficacious versus MTX-mono. Safety of filgotinib in patients with PPFs was comparable to the overall population; no new safety signals were observed.

Conclusion

FIL200 + MTX efficacy and safety in patients with multiple PPFs were similar to the overall population.

Project description:BACKGROUND:The aim was to assess patient-reported outcomes (PROs) in patients with rheumatoid arthritis (RA) treated with filgotinib during two phase 2b, 24-week, randomized, placebo-controlled studies. METHODS:Patients with moderate-to-severe active RA and an inadequate response to methotrexate (MTX) were randomized to daily placebo or filgotinib 50 mg, 100 mg, or 200 mg as add-on therapy to MTX (NCT01888874) or as monotherapy (NCT01894516). At week 12, nonresponders receiving filgotinib 50 mg in both studies or placebo in the add-on study, and all patients receiving placebo as monotherapy, were re-assigned to filgotinib 100 mg. PROs were measured using the Health Assessment Questionnaire - Disability Index (HAQ-DI) including Patient Pain assessed by visual analog scale, and the Patient Global Assessment of Disease Activity (Patient Global), the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Scale (Version 4), and the 36-Item Short Form Health Survey (SF-36). RESULTS:At week 12, improvements in all PROs, apart from the SF-36 mental component in the add-on study, were statistically better with filgotinib than placebo; some improvements were noted as early as the first assessment time point (week 1 or week 4). Filgotinib improved HAQ-DI by 0.58-0.84 points, FACIT-Fatigue by 6.9-11.4 points, Patient Global by 25.2-35.6 mm, and Pain by 24.2-37.9 mm; scores were maintained or improved to week 24. Across all PROs, more patients achieved minimal clinically important differences and normative values with filgotinib 200 mg than placebo. Patients re-assigned to filgotinib 100 mg at week 12 experienced improvements in PROs between weeks 12 to 24. CONCLUSIONS:Filgotinib as MTX add-on therapy or as monotherapy demonstrated rapid and sustained (to 24 weeks) improvements in health-related quality of life and functional status in patients with active RA.

Project description:BackgroundThe effects of filgotinib on patient-reported outcomes (PROs) from 3 trials in patients with active rheumatoid arthritis were investigated.MethodsMethotrexate (MTX)-naïve patients received filgotinib 200 or 100 mg plus MTX (FIL200+MTX, FIL100+MTX), filgotinib 200 mg monotherapy (FIL200), or MTX monotherapy through 52 weeks (NCT02886728). Patients with inadequate response (IR) to MTX (MTX-IR) received FIL200+MTX, FIL100+MTX, adalimumab 40 mg +MTX (ADA+MTX), or placebo (PBO)+MTX (rerandomized to FIL200+MTX or FIL100+MTX at week 24) through 52 weeks (NCT02889796). Patients with IR to biologic disease-modifying antirheumatic drugs (bDMARD-IR) received FIL200 or FIL100 or PBO with background stable conventional synthetic (cs) DMARDs for up to 24 weeks (NCT02873936). PROs included Health Assessment Questionnaire-Disability Index (HAQ-DI), Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) physical/mental component summary (PCS/MCS), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue), Work Productivity and Activity Impairment Questionnaire-Rheumatoid Arthritis (WPAI-RA), and Patient Global Assessment of Disease Activity (PtGA). Data are reported as least-squares mean changes from baseline with standard error to the timepoint representing each study's primary endpoint. All statistical comparisons are of filgotinib groups vs their respective control groups.ResultsAt week 24, among MTX-naïve patients, change from baseline (standard deviation) in HAQ-DI was - 1.00 (0.03; P < 0.001) with FIL200+MTX, - 0.94 (0.04; P < 0.01) with FIL100+MTX, and - 0.91 (0.04; P < 0.05) with FIL200 alone compared with - 0.81 (0.03) with MTX alone. At week 12, among MTX-IR patients, change from baseline in HAQ-DI was - 0.69 (0.04; P < 0.001 vs PBO+MTX, P < 0.05 vs ADA) with FIL200+MTX, - 0.57 (0.04; P < 0.001 vs placebo) with FIL100+MTX, and - 0.60 (0.04) with ADA vs - 0.40 (0.04) with PBO+MTX. At week 12, among bDMARD-IR patients, change from baseline in HAQ-DI was - 0.50 (0.06; P < 0.001) with FIL200+csDMARD and - 0.46 (0.05; P < 0.001) with FIL100+csDMARD vs - 0.19 (0.06) with placebo+csDMARD. Changes in SF-36 PCS and MCS, FACIT-Fatigue, WPAI, and PtGA tended to favor filgotinib over PBO, MTX, and ADA. Greater proportions of patients experienced clinically meaningful differences with either dosage of FIL in combination with csDMARDs (including MTX) and with FIL200 monotherapy vs comparators.ConclusionsFilgotinib provided improvements in PROs across patient populations. These findings suggest filgotinib can be an effective treatment option for patients with insufficient response to MTX or bDMARDs and patients who are MTX-naïve.Trial registrationClinicalTrials.gov , FINCH 1, NCT02889796 , first posted September 7, 2016; FINCH 2, NCT02873936 , first posted August 22, 2016, retrospectively registered; FINCH 3, NCT02886728 , first posted September 1, 2016, retrospectively registered.
