Budesonide foam for mild to moderate distal ulcerative colitis: A systematic review and meta-analysis

GADECCU 2022 Guideline for the treatment of Ulcerative Colitis. Adaptation and updating of the GETECCU 2020 Guideline

INTRODUCTION

Ulcerative colitis (UC) is a chronic inflammatory disease that compromises the colon, affecting the quality of life of individuals of any age. In practice, there is a wide spectrum of clinical situations. The advances made in the physio pathogenesis of UC have allowed the development of new, more effective and safer therapeutic agents.

OBJECTIVES

To update and expand the evaluation of the efficacy and safety of relevant treatments for remission induction and maintenance after a mild, moderate or severe flare of UC.

RECIPIENTS

Gastroenterologists, coloproctologists, general practitioners, family physicians and others health professionals, interested in the treatment of UC.

METHODOLOGY

GADECCU authorities obtained authorization from GETECCU to adapt and update the GETECCU 2020 Guide for the treatment of UC. Prepared with GRADE methodology. A team was formed that included authors, a panel of experts, a nurse and a patient, methodological experts, and external reviewers. GRADE methodology was used with the new information.

RESULTS

A 118-page document was prepared with the 44 GADECCU 2022 recommendations, for different clinical situations and therapeutic options, according to levels of evidence. A section was added with the new molecules that are about to be available.

CONCLUSIONS

This guideline has been made in order to facilitate decision-making regarding the treatment of UC, adapting and updating the guide prepared by GETECCU in the year 2020.

Bowel frequency (night) and urgent defecation are improved by budesonide foam in patients with ulcerative colitis: a retrospective observational study

Introduction

Patients with ulcerative colitis (UC) are known to have a significantly poor quality of life due to bowel frequency (night) and urgent defecation. Budesonide foam is a topical medication that was approved in Japan in 2017 for the treatment of UC. However, its efficacy in the treatment of bowel frequency (night) or urgent defecation is unknown. This study aimed to explore the efficacy of budesonide foam for the alleviation of these symptoms.

Methods

UC patients who received budesonide foam between December 2017 and January 2020 at the Jikei University School of Medicine in Tokyo were enrolled. The simple clinical colitis activity index (SCCAI) was evaluated at the start of budesonide foam treatment and 2 and 6 weeks later in patients who initially scored ≥ 1 for bowel frequency (night) and urgent defecation, respectively. We also studied the effect of budesonide foam on remaining symptoms in patients who had used 5-aminosalicylic acid (5-ASA) topical treatment, those with SCCAI ≥ 3, and those in remission with residual symptoms (SCCAI 1 or 2).

Results

Of the 233 enrolled patients, 102 were eligible for the study. In 36 patients with bowel frequency (night) treated with budesonide foam were significantly effective, score in SCCAI decreased from 1.17 ± 0.45 at baseline to 0.53 ± 0.61 at week 2 (p < 0.0001) and 0.17 ± 0.38 at week 6 (p < 0.0001). In 45 patients with urgent defecation score in SCCAI decreased significantly from 1.33 ± 0.52 at baseline to 0.44 ± 0.59 at week 2 (p < 0.0001) and 0.22 ± 0.40 at week 6 (p < 0.0001). Of 22 patients who switched from topical 5-ASA administration to budesonide foam, nine at week 2 (41%) and 11 (50%) at week 6 were improved with no symptoms, and there were no cases of worsened symptoms. No severe side effects associated with budesonide foam were observed.

Conclusion

Budesonide foam administration significantly improves both bowel frequency (night) and urgent defecation-related UC activity and is also effective for the patients who were refractory to topical 5-ASA administration.

GETECCU 2020 guidelines for the treatment of ulcerative colitis. Developed using the GRADE approach

INTRODUCTION

Since the first edition of the Guidelines was published in 2013, much information has been generated around the treatment of ulcerative colitis, and new drugs and action protocols have been introduced. Clinical practice has changed substantially, warranting new approaches and a comprehensive review and update of the evidence.

MATERIAL AND METHODS

Once again, we used the GRADE approach, supported by an electronic tool (https://gradepro.org). The clinical scenarios are the same as in the previous version (induction and maintenance in severe and mild-moderate flare-ups), as are the variables and their evaluation. However, in the updated guidelines, three questions have been deleted, 14 added and 30 maintained, making a total of 44 clinical questions. After an exhaustive review of the evidence, the recommendations are now updated.

RESULTS

Of the 44 questions analysed, no recommendation could be established in two due to the very low quality of the evidence, while in the other 42, based on different degrees of quality of evidence, recommendations were made according to the GRADE system. In 25 of these questions the final recommendation is strongly in favour, in six strongly against, in seven weakly in favour and in four weakly against. According to the scenarios and recommendations, six algorithms are proposed as a simple guide for practical decision-making.

CONCLUSIONS

The aim of this update of the 2013 guidelines is to provide answers, based on the GRADE approach, to the different questions we ask ourselves daily when deciding the most appropriate treatment for our patients with ulcerative colitis in the different clinical scenarios.

Budesonide MMX in the Treatment of Ulcerative Colitis: Current Perspectives on Efficacy and Safety

Budesonide MMX is a low bioavailability corticosteroid oral once-daily formulation, which has a controlled rate of release throughout the colon, thanks to the multimatrix (MMX) formulation. It has been available for a decade in the USA and Europe for the induction of remission in patients with active, mild to moderate ulcerative colitis, particularly for those not responsive to mesalamine. The efficacy of budesonide MMX in this setting has been assessed by registrative randomized controlled trials showing a higher rate of clinical and endoscopic remission at 8 weeks compared with placebo, mostly in patients with proctosigmoiditis and left-side colitis. Since it is available in our therapeutic armamentarium, a few studies have confirmed the effectiveness of budesonide MMX also in real-life, highlighting the high rate of clinical response and remission and the high safety profile. In the present review, we summarise clinical trials and real-life results of budesonide MMX, assessing its use and predictors of response and non-response in real-life.

Patients' Preference of Topical Therapy for Ulcerative Colitis in Japan: A Web-based 3T Survey

Background

The therapeutic drugs available for ulcerative colitis (UC) have recently increased. However, use of topical therapy for UC in Japan has not been determined. This study aimed to investigate real-world use of topical therapy for UC in Japan using a web-based survey designed for UC patients.

Methods

A web-based questionnaire on UC management was administered to 773 patients over a 2-day period in September 2019. The responses regarding topical therapy use were analyzed.

Results

Questionnaire responses were obtained from 323 UC patients. Of these, the mean disease duration was 12.2 years, and 220 patients (68.1%) had used topical therapy, of whom 68 (21.1%) were currently using this treatment. The frequency of using the prescribed topical therapy was appropriate in 36.8% of patients, only when needed in 38.6%, and rarely in 24.5%. Among all topical therapy users, 64.4% reported that budesonide foam was easy to use, which was significantly higher than the rates for mesalazine suppositories (43.6%), mesalazine enemas (12.9%), and glucocorticoid enemas (13.9%; P < 0.05). Regarding treatment effects, 68.9% of patients were satisfied with the budesonide foam, which was a significantly higher rate of satisfaction than those for mesalazine suppositories (44.6%), mesalazine enemas (30.2%), glucocorticoid enemas (36.1%), and glucocorticoid suppositories (41.9%; P < 0.05).

Conclusions

Although topical therapy use was common in this Japanese UC population, patient adherence was not very high. Of all the topical therapy types, budesonide foam, which has recently become available, was rated highly by these patients.

Recommendations of the Spanish Working Group on Crohn's Disease and Ulcerative Colitis (GETECCU) on topical therapy in ulcerative colitis

Although most patients with ulcerative colitis should be given topical treatment, different studies have shown that they are underused in clinical practice. The purpose of this article is to answer 10 specific questions about which drugs are available for topical use in the treatment of ulcerative colitis, and their characteristics in terms of formulation, dosage, presentation, application and proximal distribution of rectal-administered drugs. The efficacy of available topical drugs and the benefits of combining different formulations and routes of administration, and their usefulness during disease remission are evaluated. Finally, a series of recommendations addressed to patients are given on the correct application of topical treatment.

An approach to acute severe ulcerative colitis

Introduction: Despite the introduction of novel therapies and treatment strategies for ulcerative colitis (UC), many patients develop acute, severe episodes, warranting prompt care and aggressive management. There is a significant unmet need to improve outcomes in these patients. Clinicians must be able to identify those that will have worse prognosis and plan an aggressive therapy with an early/proactive adjustments in management if needed.Areas covered: The aim of this review is to evaluate the most recent evidence on the assessment and management of patients with acute severe ulcerative colitis. We searched the mainstream literature search engines for the most recent evidence on diagnosis and management of acute UC.Expert Opinion: The approach to patients with severe UC includes clinical and endoscopic assessment of disease severity and ruling out over-infections. While intravenous corticosteroids remain the first line therapy for acute severe colitis, many patients do not respond and require escalation to calcineurin inhibitors or infliximab, and may ultimately require colectomy. Even though several novel therapies are available or in development, their role in acute severe episodes of colitis is unknown.

Efficacy of budesonide-loaded mesoporous silica microparticles capped with a bulky azo derivative in rats with TNBS-induced colitis

A colon targeted drug delivery system for inflammatory bowel diseases (IBD), consisting in budesonide loaded mesoporous silica microparticles functionalized with a selective azo-molecular gate (M-Bud), has been evaluated for in vivo efficacy. Experimental colitis in male Wistar rats was induced by rectal instillation of 2,4,6-trinitrobenzenesulfonic acid (TNBS). M-Bud was orally administered to the rats as a suspension in water. Colon/body weight ratio, clinical activity score, and histological evaluation were used as inflammatory indices to measure the performance of the microparticles. The formulation was compared with a suspension prepared from the commercial drug Entocord®. Statistical analyses of all scores indicate that the controlled release of budesonide in colon from M-Bud showed efficacy similar to that of Entocord in the healing of induced colitis in rats.

Mesoporous silica microparticles gated with a bulky azo derivative for the controlled release of dyes/drugs in colon

Mesoporous silica microparticles were prepared, loaded with the dye safranin O (M-Saf) or with the drug budesonide (M-Bud) and capped by the grafting of a bulky azo derivative. Cargo release from M-Saf at different pH values (mimicking those found in the gastrointestinal tract) in the absence or presence of sodium dithionite (a reducing agent mimicking azoreductase enzyme present in the colon) was tested. Negligible safranin O release was observed at pH 6.8 and 4.5, whereas a moderate delivery at pH 1.2 was noted and attributed to the hydrolysis of the urea bond that linked the azo derivative onto the external surface of the inorganic scaffold. Moreover, a marked release was observed when sodium dithionite was present and was ascribed to the rupture of the azo bond in the molecular gate. Budesonide release from M-Bud in the presence of sodium dithionite was also assessed by ultraviolet-visible spectroscopy and high performance liquid chromatography measurements. In addition, preliminary in vivo experiments with M-Saf carried out in mice indicated that the chemical integrity of the microparticles remained unaltered in the stomach and the small intestine, and safranin O seemed to be released in the colon.
