Effects of JAK1-Preferential Inhibitor Filgotinib on Circulating Biomarkers and Whole Blood Genes/Pathways of Patients With Moderately to Severely Active Crohn's Disease.

ABSTRACT:

Background

Pro-inflammatory cytokines are dysregulated in Crohn's disease (CD) and could serve as surrogate markers to improve diagnostic and therapeutic approaches, potentially addressing an unmet need. We profiled circulating biomarkers and whole blood transcriptional pathway activity to identify those associated with CD using data from the phase 2 FITZROY study with filgotinib, an oral preferential janus kinase-1 inhibitor.

Methods

Patients with serum and whole blood samples taken from the induction period were included. Serum cytokines were measured (ELISA), whole blood RNA sequenced, and stool samples taken to measure fecal calprotectin (FC). Spearman's Rank correlations were assessed between biomarkers and baseline disease activity; post-treatment endoscopic improvement was measured by the Simplified Endoscopy Score for CD (SES-CD), FC and the Crohn's Disease Activity Index. Effect of filgotinib on circulating biomarkers was also evaluated.

Results

Serum biomarkers (n = 168) and whole blood RNA sequencing (n = 104) were assessed. Moderate correlation between serum analytes with SES-CD and FC was noted; most highly correlated were acute phase proteins CRP (rho = 0.35 [SES-CD] and 0.47 [FC]), serum amyloid A (rho = 0.40 and 0.39, respectively) and pro-inflammatory cytokines interleukin (IL)-6 (rho = 0.31 and 0.30, respectively), IL-22 (rho = 0.36 and 0.35, respectively), and oncostatin M (rho = 0.35 and 0.33, respectively). Filgotinib treatment was associated with reduction of many candidate biomarkers, particularly in patients with treatment response. Early changes in IL-6 and IL-10 may be prognostic for endoscopic response.

Conclusions

Several circulating factors with potential as CD activity biomarkers were identified. Larger studies are necessary to investigate the best utility of these markers for CD.

Project description:BackgroundWhere head-to-head trials are lacking, indirect comparative effectiveness can aid treatment decisions. We conducted matching-adjusted indirect comparisons of clinical outcomes with filgotinib vs recently approved comparators (vedolizumab, tofacitinib, ustekinumab) in patients with moderately to severely active ulcerative colitis (UC).MethodsIndividual patient data from the SELECTION trial (NCT02914522) for filgotinib 200 mg were weighted to match average baseline characteristics of active treatment and placebo arms in comparator trials. Efficacy outcomes were compared for biologic-naive and biologic-experienced subgroups in induction and maintenance populations, if data were available. Safety and health-related quality of life outcomes were compared in the overall maintenance population.ResultsFilgotinib had a similar effect on efficacy outcomes compared with tofacitinib, ustekinumab, and subcutaneous vedolizumab in both the induction and maintenance populations. Filgotinib showed improved clinical response vs intravenous (IV) vedolizumab (odds ratio, 2.4; 95% confidence interval [CI], 1.0 to 5.5; P < .05) among the biologic-experienced induction population, and improved corticosteroid-free clinical remission (odds ratio, 15.2; 95% CI, 1.6 to 139.9; P < .05) among the biologic-naive maintenance population. Improved efficacy outcomes were reported with filgotinib compared with ustekinumab among the maintenance population. Higher estimates of serious adverse events were reported for filgotinib compared with vedolizumab IV 300 mg and tofacitinib 5 mg; however, imbalances were noted in their placebo groups. Health-related quality of life outcomes were similar between filgotinib and comparators.ConclusionsMatching-adjusted indirect comparison results suggest superiority of filgotinib 200 mg over vedolizumab IV in terms of clinical response and corticosteroid-free clinical remission in certain patient populations, noting small sample sizes and wide CIs, which may aid the selection of advanced therapies for moderately to severely active UC. A potential increased risk of serious adverse events was reported for filgotinib 200 mg vs vedolizumab IV and tofacitinib 5 mg, but findings should be interpreted with caution owing to underlying imbalances observed between the placebo groups of SELECTION and comparator trials.

Project description:Background and aimsCorticosteroid-free remission is an important treatment goal for patients with ulcerative colitis [UC]. The corticosteroid-sparing effects of filgotinib, an oral, Janus kinase 1 preferential inhibitor, were assessed in SELECTION, a placebo-controlled, phase 2b/3 trial in moderately to severely active UC.MethodsThese post hoc analyses assessed 1-, 3-, 6-, and 8-month rates of corticosteroid-free clinical remission at Week 58 and change in median daily prednisone-equivalent dose over time. A matching-adjusted indirect comparison [MAIC] of maintenance studies assessed corticosteroid-free remission with filgotinib 200 mg, intravenous vedolizumab, subcutaneous vedolizumab, and oral tofacitinib.ResultsThe Maintenance Study full analysis set included 199 patients receiving filgotinib 200 mg and 98 receiving placebo. Among patients receiving corticosteroids at Maintenance Study baseline, at Week 58, 30.4%, 29.3%, 27.2%, and 21.7% receiving filgotinib had been in corticosteroid-free remission for ≥1, ≥3, ≥6, or ≥8 months, respectively, versus 6.4% receiving placebo across thresholds [p <0.05]. Median daily prednisone-equivalent dose decreased from 17.5 mg/day to 10.0 mg/day with filgotinib treatment during the Maintenance Study. Based upon the MAIC, filgotinib was associated with greater likelihood of corticosteroid-free clinical remission versus intravenous vedolizumab (odds ratio [OR], 15.2; 95% confidence interval [CI], 1.6-139.9; p <0.05]) and similar odds to subcutaneous vedolizumab [OR, 3.8; CI, 0.2-63.8; p = 0.36] in biologic-naïve patients, and similar odds to tofacitinib overall [OR, 2.0; 0.4-9.1; p = 0.39].ConclusionsFilgotinib 200 mg demonstrated corticosteroid-sparing effects and maintained corticosteroid-free clinical remission in patients with UC. MAIC results should be interpreted cautiously given the large CIs and differences in study design and patient populations. [ClinicalTrials.gov: NCT02914522].

Project description:IntroductionRisankizumab (RZB) and ustekinumab (UST), interleukin (IL)-23 and IL-12/23 inhibitors, respectively, are approved treatments for moderately to severely active Crohn's disease (CD); direct comparison between the two is ongoing. We indirectly compared efficacy of RZB versus UST using data from phase 3 trials (RZB: NCT03104413; NCT03105128; NCT03105102; UST: NCT01369329; NCT01369342; NCT01369355).MethodsMatching-adjusted indirect comparison was conducted using individual patient-level data from RZB trials and published aggregated data from UST trials. During induction, patients received RZB 600 mg intravenous (IV) at weeks 0, 4, and 8 or a single dose of UST 6 mg/kg IV at week 0. During maintenance, patients received RZB 180 or 360 mg subcutaneous (SC) or UST 90 mg SC every 8 or 12 weeks to 52 weeks. Outcomes included proportion of patients achieving Crohn's Disease Activity Index (CDAI) response (decrease of ≥ 100 points or total score < 150) or remission (CDAI ≤ 150) and endoscopic improvement (measured by the Simple Endoscopic Score in CD [SES-CD]; response, ≥ 50% reduction from baseline; remission, SES-CD ≤ 2) following induction/baseline.ResultsHigher proportions of patients achieved clinical and endoscopic outcomes with RZB vs. UST induction treatment, resulting in significantly (p ≤ 0.05) greater percent differences (95% confidence intervals) between groups for CDAI remission (15% [5%, 25%]) and endoscopic response (26% [13%, 40%]) and remission (9% [0%, 19%]). Following maintenance, rates of CDAI remission were similar (range - 0.3% to - 5.0%) for RZB vs. UST. Differences for endoscopic response and remission ranged from 9.3% to 27.7% and 11.6% to 12.5%, respectively; differences were significant (p < 0.05) for endoscopic response for both doses of RZB compared to UST 12-week dosing.ConclusionsThis indirect comparison demonstrated higher rates of clinical and endoscopic outcomes during induction for RZB compared to UST; CDAI remission following maintenance was comparable. Direct comparisons of RZB and UST are warranted to validate these findings.
