Effectiveness of golimumab in inducing remission and clinical response in outpatient ulcerative colitis

Effectiveness of golimumab in patients with ulcerative colitis: results of a real-life study in Switzerland

BACKGROUND

Tumor necrosis factor (TNF) inhibitors have improved treatment of ulcerative colitis (UC), but loss of response remains a frequent problem. The anti-TNF agent, golimumab, was approved in Switzerland for the treatment of UC in 2014. This study aims to summarize the experience of golimumab in a real-world setting in Switzerland.

METHODS

We analyzed real-world data from 1769 UC patients from the Swiss Inflammatory Bowel Disease Cohort (SIBDC) study and performed a chart review of golimumab-treated patients. We extracted the partial Mayo score at t₀ (baseline), t₁ (2-16 weeks), t₂ (17-35 weeks), and t₃ (36-89 weeks). The primary endpoint was clinical response at t₁, defined as marked improvement in partial Mayo score and objective parameters. Clinical remission was defined as resolution of symptoms and normalization of objective parameters.

RESULTS

Our chart review included 103 UC patients with golimumab treatment (5.8% of all SIBDC UC patients); only 16 (15.5%) were anti-TNF naïve. Sixty-three patients remained on golimumab (61.2%) after 180 days, 51 (44.7%) after 365 days, and 34 (33%) after 630 days after the start of treatment. Upon golimumab treatment, the partial Mayo score decreased from 4 [interquartile range (IQR): 2-6] at t₀ to 2 (IQR: 0-4) at t₁, 1 (IQR: 0-3.5) at t₂, and 1 (IQR: 0-3) at t₃ (p < 0.001 for all comparisons with t₀). The primary endpoint, clinical response at t₁, could be evaluated in 52 patients and was met in 15 individuals (28.8%). Clinical remission at t₁ was observed in 8 out of 52 patients (15.4%). Golimumab was generally well tolerated, one patient developed meningitis. The most frequent reasons to stop treatment were primary and secondary non-response.

CONCLUSION

Golimumab was used in 5.8% of Swiss UC patients, mainly in biologic-experienced individuals. Golimumab treatment was associated with a sustained reduction of symptoms and clinical response in approximately 30% of patients.[ClinicalTrials.gov identifier: NCT00488631].

Effectiveness and Safety of Golimumab in Patients with Ulcerative Colitis: A Multicenter, Prospective, Postmarketing Surveillance Study

Background/Aims

Golimumab has been used for patients with ulcerative colitis (UC) since 2013. However, there is limited data on the effectiveness and safety of the real-world use of golimumab in Asian patients.

Methods

This was a multicenter, prospective, observational study. We enrolled patients with moderate-to-severe UC who were administered subcutaneous golimumab at 46 medical centers between May 2014 and November 2019. The primary outcome was the effectiveness and safety of golimumab at week 22. Clinical outcomes and adverse events were assessed according to partial Mayo score at weeks 0, 2, 6, 14, and 22.

Results

A total of 130 patients were included (mean age 45.7±16.0 years). The clinical response/remission rates at weeks 2, 6, 14, and 22 were 40.4%/22.9%, 56.0%/35.8%, 70.6%/49.5%, and 67.9%/48.6%, respectively. Based on full Mayo score at week 14, clinical response and remission rates were 84.2% and 39.5%, respectively. Mucosal healing rate was 65.8%. In multivariate analysis with logistic regression, longer disease duration was significantly associated with a higher clinical response rate (adjusted odds ratio [aOR], 1.136; 95% confidence interval [CI], 1.006 to 1.282; p=0.040 at week 6; aOR, 1.256; 95% CI, 1.049 to 1.503; p=0.013 at week 22). A higher baseline Mayo endoscopic subscore was significantly associated with a lower clinical response rate at week 6 (aOR, 0.248; 95% CI, 0.089 to 0.692; p=0.008). The incidence of adverse drug reactions was 4.6% (6/130, nine events). No serious unexpected adverse drug reactions or deaths were reported.

Conclusions

Golimumab was effective and safe as an induction and maintenance treatment for Korean patients with moderate-to-severe UC.

Golimumab Dried Blood Spot Analysis (GOUDA): a Prospective Trial Showing Excellent Correlation with Venepuncture Samples and More Detailed Pharmacokinetic Information

Development of a dried blood spot (DBS) method for golimumab will facilitate sample collection in a study setting and will give a more complete insight in the total drug exposure (area under the curve, AUC). We established a DBS method and assessed its robustness, user-friendliness and clinical usefulness in 10 patients with ulcerative colitis during golimumab induction and maintenance regimens. DBS was obtained through spotting of golimumab spiked in whole citrated blood to a filter paper. Several extraction conditions were evaluated and the selected extraction condition analytically validated. In a clinical setting, DBS and serum samples were taken simultaneously through intensive sampling regimens and a conversion factor was determined. Golimumab concentrations were measured using an in-house-developed ELISA and a CE-marked ELISA kit. User-friendliness was evaluated using a questionnaire. Mucosal healing was evaluated at week 14. A total of 79 matched pairs of serum and DBS sample golimumab concentrations revealed an overall conversion factor of 3.9. DBS golimumab concentrations after conversion correlated strongly with serum golimumab concentrations (ICC = 0.984). During induction, no linear correlation was found between golimumab trough concentration (TC) and AUC (R² = 0.29). Multiple peaks emerged during drug absorption. Patients who achieved mucosal healing appeared to have less fluctuating TC and a constant AUC over time. Nine out of 10 patients reported DBS sampling as user-friendly. The GOUDA study showed that DBS sampling is a robust and patient-friendly alternative to venous blood collection. DBS sampling may provide better insights into golimumab absorption and exposure.

Golimumab effectiveness and safety in clinical practice for moderately active ulcerative colitis

BACKGROUND AND AIMS

Golimumab (GLB) is an antitumour necrosis factor-α (anti-TNF) therapy that has shown efficacy as induction and maintenance therapy for ulcerative colitis (UC). We aimed to describe the outcome of GLB therapy for UC in a real-world clinical practice.

PATIENTS AND METHODS

Consecutive patients receiving GLB for UC in six Irish Academic Medical Centres were identified. The primary study endpoint was the 6-month corticosteroid-free remission rate. The secondary endpoints included the 3-month clinical response, time free of GLB discontinuation and adverse events.

RESULTS

Seventy-two patients were identified [57% men; median (range) age of 41.4 years (20.3-76.8); disease duration 6.6 years (0-29.9); follow-up 8.7 months (0.4-39.2)]. Sixty-four percent of patients were anti-TNF naive. The 3-month clinical response and the 6-month corticosteroid-free remission rates were 55 and 39%, respectively. Forty-four percent of patients discontinued GLB during the follow-up, median (95% confidence interval) time to GLB discontinuation 18.7 months (9.2-28.1). A C-reactive protein more than 5 mg/l at baseline was associated with failure to achieve 6-month corticosteroid-free remission and a shorter time to GLB discontinuation, odds ratio 0.2 (0.1-0.7), P=0.008, and hazard ratio (95% confidence interval) 2.8 (1.3-5.7), P=0.007, respectively. Adverse events occurred in 7% of patients (n=5), all of which were minor and self-limiting.

CONCLUSION

These real-world clinical data suggest that GLB is an effective and safe therapy for a UC cohort with significant previous anti-TNF exposure. An elevated baseline C-reactive protein, likely reflective of increased inflammatory burden, is associated with a reduced likelihood of a successful outcome of GLB therapy.

Clinical efficacy and safety of golimumab in biologically experienced and naive patients with active ulcerative colitis: A real-life experience from two Italian IBD centers

OBJECTIVE

To evaluate the efficacy and safety of golimumab in biological naive and experienced patients with moderately to severely active ulcerative colitis (UC) treated at two Italian IBD centers.

METHODS

We retrospectively reviewed our prospectively maintained UC database from March 2015 to March 2017. Patients received golimumab 200 mg at week 0, 100 mg at week 2, then 50 mg or 100 mg every 4 weeks. Follow-up was recorded at 12 and 24 weeks and in March 2017, with a median follow-up of 64 weeks. The main outcomes evaluated were clinical remission (CR) and adverse event rates.

RESULTS

Of the 59 patients (44% naive and 56% experienced), CR rate was 47% at 12-week follow-up, 55% (among the 49 patients on treatment) at 24-week follow-up and 49% (among 35 patients on treatment) at the last follow-up visit. Median treatment duration was 52 weeks (interquartile range 30-64 weeks) among patients treated for >6 months. Overall, 10 (17%) patients experienced adverse events, of whom 50% discontinued treatment. The most frequent adverse events were infections. Biological naive and experienced patients did not differ in terms of CR and adverse event rates.

CONCLUSIONS

Our real-life experience showed that CR decreased over time and was achieved by almost one-third of the cohort at the last follow-up visit. Golimumab showed an overall favorable safety profile and the results were not different between biological naive and experienced patients. Future research is needed to confirm our results and to identify criteria to select patients most likely to respond.

Golimumab: early experience and medium-term outcomes from two UK tertiary IBD centres

OBJECTIVE

To gain an understanding of the effectiveness of golimumab in a 'real-world' setting.

DESIGN

Retrospective cohort study using prospectively maintained clinical records.

SETTING

Two UK tertiary IBD centres.

PATIENTS

Patients with ulcerative colitis (UC) were given golimumab at Guy's & St Thomas and King's College Hospitals between September 2014 and December 2016.

INTERVENTION

Golimumab, a subcutaneously administered antitumour necrosis factor agent.

MAIN OUTCOME MEASURES

Clinical disease activity was assessed at baseline and at the first clinical review following induction therapy using the Simple Clinical Colitis Activity Index (SCCAI). Response was defined as an SCCAI reduction of 3 points or more. Remission was defined as an SCCAI of less than 3.

RESULTS

Fifty-seven patients with UC completed golimumab induction therapy. Paired preinduction and postinduction SCCAI values were available for 31 patients and fell significantly from 7 (2-19) to 3 (0-11) (p<0.001). To these 31, an additional 13 patients who did not have paired SCCAI data but stopped treatment due to documented 'non-response' in the opinion of their supervising clinician, were added. Among this combined cohort, 23/44 (52%) had a clinical response, 15/44 (34%) achieved remission and 13/44 (30%) achieved corticosteroid-free remission.Faecal calprotectin and CRP fell (FC: pre-induction: 1096 (15-4800) μg/g, post-induction: 114 (11-4800) μg/g, p = 0.011; n = 20; CRP: pre-induction: 4 (1-59) mg/L, post-induction: 2 (1-34) mg/L, p = 0.01 for n = 43). Post-induction endoscopy was carried out in 23 patients and a mucosal healing (Mayo 0 or 1) rate of 35% was observed.

CONCLUSIONS

Our experience mirrors previously reported real-world cohorts and demonstrates similar outcomes to those observed in randomised controlled trials. These data demonstrate a meaningful reduction in clinical, biochemical and endoscopic disease activity as well as a steroid-sparing effect in patients with previously refractory disease.

Clinical Outcomes of Golimumab as First, Second or Third Anti-TNF Agent in Patients with Moderate-to-Severe Ulcerative Colitis

BACKGROUND

Golimumab efficacy data in ulcerative colitis (UC) are limited to anti-tumor necrosis factor α (TNF)-naive patients. The aim of this study was to assess the short-term and long-term efficacy of golimumab used as first, second, or third anti-TNF in UC in a real-life clinical setting.

METHODS

This retrospective multicenter cohort study included patients with moderate-to-severe UC treated with golimumab. The primary efficacy endpoints were short-term partial Mayo score response, long-term golimumab failure-free survival, and colectomy-free survival.

RESULTS

In 142 patients with UC, golimumab was administered as first (40%), second (23%), or third anti-TNF (37%). Ninety-two patients (65%, 95% confidence interval 56.6-73) achieved short-term clinical response. Forty-five patients (32%, 95% confidence interval 23.7-39.7) achieved clinical remission. Response rates for golimumab were 75% as first anti-TNF, 70% as second anti-TNF (ns versus first anti-TNF), and 50% as third anti-TNF (P = 0.007 versus first anti-TNF). After 12 months median follow-up (interquartile range 6-18), 60 patients (42%, 95% confidence interval 34-51) had golimumab failure, and 15 patients (11%) needed colectomy. Thirty-one patients (22%) needed golimumab dose escalation, and 71% of these regained response after escalation. Starting maintenance with 100 mg golimumab doses and short-term nonresponse were independent predictors of golimumab failure.

CONCLUSIONS

In this real-life cohort of patients with UC, golimumab therapy was effective for inducing and maintaining clinical response. Although anti-TNF-naive patients had better outcomes, golimumab was also effective in anti-TNF-experienced patients. Only the patients given golimumab after previous failure of 2 anti-TNF agents had significantly worse outcomes. Golimumab dose escalation was beneficial and safe.

Golimumab for moderate to severe ulcerative colitis

Golimumab (GLM) is a subcutaneously administered human anti-tumor necrosis factor (TNF) agent that has been approved by the regulatory authorities for the treatment of moderate to severe ulcerative colitis (UC) in 2013. Areas covered: Maintained clinical remission rates up to 50% have been shown in UC patients receiving GLM, and higher GLM serum concentrations have been associated with improved clinical outcomes. Approximately 50% of UC patients do not respond to induction therapy with GLM, and up to 40% of GLM responders will lose response over time. In most patients, loss of response is associated with low serum GLM concentrations, which suggests insufficient exposure to GLM. Low GLM serum concentrations may be avoided by therapeutic drug monitoring. Expert commentary: So far, the therapeutic window for GLM has not yet been defined, but options to dose increase GLM based on therapeutic drug monitoring might result in improved clinical outcome and higher success rates.
