Abstract Background The first multicentre paediatric randomised-controlled trial (RCT) of faecal microbiota transplant (FMT) in ulcerative colitis (UC) was recently completed in Ontario and Quebec, Canada. The use of FMT in paediatric UC treatment has been limited to small, open-label case series. Unique clinical and patient factors necessitated a paediatric-specific pilot RCT. Our aim was to assess key feasibility measures of conducting an FMT trial in paediatric patients to inform design, and feasibility of larger, future multicentre studies. Methods Patients were randomised (1:1) to receive rectal enemas 2×/week for 6 weeks, followed by a 6-month follow-up period. Enemas contained normal saline (placebo), or RBX2660 (Rebiotix; Roseville, USA), a faecal microbiota preparation of stool from healthy adult donors (active). Patients were eligible for the open-label extension following completion or withdrawal from the placebo arm. Study feasibility was assessed through patient eligibility, recruitment, completion of sample collections, adverse events, and hospitalisations. Results Over 36 months across two tertiary IBD clinics, 48 paediatric patients were screened for participation. 75.0% (36) met eligibility criteria for enrolment and 69.4% (25) participated in the randomised trial. 53.8% (7) of patients randomised to the placebo arm entered the open-label arm. We stratified completion of sample collections by intervention (Weeks 0–6), and follow-up phases of the trial (Weeks 6–30). 75.3% of required bloodwork was obtained during both phases; patient-provided stool samples declined from 76.0% (intervention) to 45% (follow-up). 83.0% (10) reported adverse events in the active arm, and 38.4% (5) in placebo; these were all minor and self-limited (muscle pain, cough, fatigue, etc.). No patients experienced adverse events related to enemas. Five patients experienced serious adverse events: IBD flare (2 active, 1 placebo), and reactivation of C. difficile infection (2 active) (Table 1). Conclusion In this first paediatric RCT of FMT for UC, we established important feasibility data regarding the design of FMT trials in children. Patient acceptance of FMT was high, and well-tolerated with minor, self-limited adverse events, and few serious adverse events. Return-rates of stool samples were low during follow-up; strategies to improve uptake are needed, particularly given the value of microbiome data for analyses. Overall, our study demonstrates strong interest and tolerance among paediatric patients for FMT-based trials. Future studies will build upon our protocol to enhance clinical data on the effects of microbiota-based therapeutics in children.

ObjectivesTo determine the long-term safety and efficacy of allopurinol dose escalation (DE) to achieve target serum urate (SU) in gout.MethodsPeople, including those with chronic kidney disease, who completed the first 12 months of a randomised controlled trial continued into a 12-month extension study. Participants randomised to continue current dose for the first 12 months began allopurinol DE at month 12 if SU was ≥6 mg/dL (control/DE). Immediate DE participants who achieved target SU maintained allopurinol dose (DE/DE). The primary endpoints were reduction in SU and adverse events (AEs) at month 24.ResultsThe mean (SE) change in SU from month 12 to 24 was −1.1 (0.2) mg/dL in control/DE and 0.1 (0.2) mg/dL in DE/DE group (p<0.001). There was a significant reduction in the percentage of individuals having a gout flare in the month prior to months 12 and 24 compared with baseline in both groups and in mean tophus size over 24 months, but no difference between randomised groups. There were similar numbers of AEs and serious adverse events between groups.ConclusionsThe majority of people with gout tolerate higher than creatinine clearance-based allopurinol dose and achieve and maintain target SU. Slow allopurinol DE may be appropriate in clinical practice even in those with kidney impairment.Trial registration numberACTRN12611000845932

Abstract Background The role of faecal microbiota transplant (FMT) for the treatment of ulcerative colitis (UC) has been reported across 4 randomised-controlled trials (RCT) in adults. Promising data have emerged from small, open-label paediatric case series and case reports but a proper blinded, placebo-controlled RCT has not been described in children. We report results from the first multicentre RCT of FMT in paediatric UC patients, conducted over 36 months in Ontario and Quebec, Canada. Methods We enrolled 25 children, ages 4–17 years old with active UC across two tertiary IBD clinics. Patients had active inflammation and remained on stable doses of medication at entry. Blinded participants received enemas containing healthy donor stool (active) or normal saline (placebo), 2×/week for 6 weeks. Faecal calprotectin (fCal), C-reactive protein (CRP), and paediatric ulcerative colitis activity index (PUCAI) scores were compared between groups during intervention, and at four follow-up time points over 30 weeks. Donor and recipient stools were measured for 16s rRNA and metagenomics analyses. Results In intention-to-treat (ITT) analysis, FMT (n = 13) at 6 weeks was more likely to improve clinical response (OR 9.3, 95% CI [0.7, 122.6]), CRP (OR 4.7, 95% CI [0.8, 28.4]), and fCal (OR 13.3, 95% CI [1.1, 166.4]) from baseline compared with placebo (n = 12). FMT at 30 weeks was also more likely than placebo to improve clinical response, CRP, and fCal (Table 1). In ITT analysis of the open-label arm (n = 7), FMT at 6 weeks and 30 weeks decreased CRP (−42.9%, −28.6%), fCal (−28.6%, −42.9%), and PUCAI score (−14.3%, −42.9%) from baseline. Conclusion Serial FMT enemas containing healthy donor microbiota led to greater improvements in serum and stool inflammatory markers, and rates of clinical response, in paediatric patients with active UC compared with placebo. These improvements largely persisted beyond 6 months after final FMT treatment. This study offers the strongest preliminary evidence, from a blinded, placebo-controlled multicentre RCT for the role of FMT in the management of paediatric UC.

Objective:The purpose of present study was to evaluate the efficacy of the addition of reboxetine in patients that had not previously responded, or had done so only partially, over 6 weeks of conventional pharmacological treatment with venlafaxine.Methods:This open-label, prospective and multicentric study included 40 outpatients diagnosed with major depressive disorder according to the DSM-IV criteria. Efficacy was assessed using the 21-item Hamilton Depression Rating Scale (HAMD) and the Clinical Global Impression-Improvement (CGI-I). Safety was evaluated by recording spontaneously reported adverse events. Data were analysed on an intent-to-treat basis, using the last-observation-carried-forward method.Results:Mean HAMD reduction was 34.9% (P < 0.0001). The percentages of responders (≥50% reduction in HAMD) and patients considered as benefiting from complete remission (HAMD ≤ 10 points) at week 6 were 27.5 and 12.5%, respectively. By the end of the treatment, the score of CGI-I decreased 24.8% (P < 0.0001). Percentage of patient improving (CGI < 4 points) was 47.5%. The most common non-serious adverse events were constipation, nervousness, anxiety and insomnia.Conclusion:These findings suggest that the combined treatment of reboxetine and venlafaxine, in venlafaxine-resistant patients, may be an effective and well-tolerated strategy.

Abstract Background: Targeted lung denervation (TLD) is a novel bronchoscopic therapy that disrupts parasympathetic pulmonary nerve input to the lung reducing clinical consequences of cholinergic hyperactivity. The AIRFLOW-1 study assessed safety and TLD dose in patients with moderate-to-severe, symptomatic COPD. This analysis evaluated the long-term impact of TLD on COPD exacerbations, pulmonary function, and quality of life over three years of follow up.Methods: TLD was performed in a prospective, energy-level randomized (29 W vs 32 W power), multicenter study (NCT02058459). Additional patients were enrolled in an open label confirmation phase to confirm improved gastrointestinal safety after procedural modifications. Durability of TLD was evaluated at one, two, and three years post-treatment and assessed through analysis of COPD exacerbations, pulmonary lung function, and quality of life. Results: Three-year follow-up data were available for 73.9% of patients (n=34). The annualized rate of moderate to severe COPD exacerbations remained stable over the duration of the study. Lung function (FEV1, FVC, RV, and TLC) and quality of life (SGRQ-C and CAT) remained stable over three years of follow-up. No new gastrointestinal adverse events and no unexpected serious adverse events were observed. Conclusion: TLD in COPD patients demonstrated a positive safety profile out to three years, with no late-onset serious adverse events related to denervation therapy. Clinical stability in lung function, quality of life, and exacerbations were observed in TLD treated patients over three years of follow up.

Antibiotic Combination

Aims: An antibiotic combination of amoxicillin, tetracycline and metronidazole (ATM) is effective for ulcerative colitis (UC), but this regimen is discontinued in some cases due to adverse events. This study aimed to assess a revised combination, namely, amoxicillin, fosfomycin and metronidazole (AFM), in UC patients with the goal of reducing side effects while maintaining therapeutic efficacy. Methods: A prospective open-label trial was undertaken in 104 adult UC patients. A combination of oral amoxicillin (1500 mg), fosfomycin (3000 mg) and metronidazole (750 mg) was administered to patients daily for 2–4 weeks in addition to their conventional medication. Clinical assessment was performed using the Lichtiger index before treatment and at 0, 3, 6, 9 and 12 months and 2 and 3 years. Endoscopic evaluation was performed using the Mayo score before treatment and at 3 and 12 months. Results: The compliance rate was 99.2%. Response and remission rates were 80.8% and 63.5% at completion, 73.1% and 64.4% at 3 months, and 39.4% for both at 12 months, respectively. Of the 41 patients who were in remission at 12 months, 63.4% maintained that status until the 2-year follow-up. Similarly, 69.2% of those in remission at 2 years remained relapse free at the 3-year follow-up. Side effects were observed in 44.2% of the participants. Fever occurred in one patient (1.0%), which was lower than the rate observed with ATM therapy. Conclusion: These results indicate that AFM therapy induces remission and is appropriate for long-term maintenance of UC while producing fewer and milder adverse events than ATM therapy. Clinical trials: This study was registered in the University Hospital Medical Information Network (No. R000046546).

Background:We compared the clinical effectiveness of a new peritoneal dialysis (PD) product with polyvinyl chloride-containing tubing (Stay Safe Link®, SSL) with the plastic-free alternative (Stay Safe®, STS) in patients on continuous ambulatory peritoneal dialysis (CAPD).Method:A multicentre, parallel, randomised, controlled, open-label, non-inferiority trial was conducted. Adult patients receiving CAPD were randomised in a 1:1 ratio to SSL or STS. The primary outcome was the rate of peritonitis after 1 year of follow-up.Results:A total of 472 subjects were randomised (SSL, n = 233; STS, n = 239). One subject in each group was excluded from the analysis as they withdrew consent before the first dialysis dose. Four hundred and seventy subjects (SSL, n = 232; STS, n = 238) were included in the modified intention-to-treat analysis. Non-inferiority between two groups was established as no significant difference was found in peritonitis rate (incident rate ratio: 0.91, 95% CI: 0.65–1.28). No significant difference was detected in weekly Kt/V ( p = 0.58) and creatinine clearance ( p = 0.55). However, the average ultrafiltration volume was significantly lower in SSL, with a mean difference of 93 ml ( p < 0.01). SSL also demonstrated a 2.57-times higher risk of device defect than STS (95% CI: 1.77–3.75).Conclusion:SSL was non-inferior in peritonitis rate compared to plastic-free STS over 1 year in patients requiring CAPD. There was no difference in the delivered dialysis dose, but there was a higher rate of device defects with SSL.

4037 Background:K-Ras mutation G12D is most prevalent in pancreatic adenocarcinoma (PDAC). siRNA against the K-RasG12D(siG12D) mutant had showed significant preclinical anti-tumor effects. siG12D LODER - miniature biodegradable polymeric matrix that encompasses anti-K-RasG12D siRNA drug, is placed with Endoscopic US biopsy and designed to continuously release the drug regionally over a period of 4 months. Methods: Open label phase I study of patients with locally advanced non-operable PDAC in the first-line setting. Patients were assigned to receive siG12D LODERs in dose escalation cohorts: 0.025mg, 0.75mg and 3.0mg. Gemcitabine 1000 mg/m2IV was given weekly, following siG12D LODER insertion. The RP2D (recommended phase II dose) was further examined in 3.0 mg dose cohort in combination with modified Folfirinox (Oxaliplatin 85mg/m2, Irinotecan 150mg/m2, Fluorouracil infusion 2,400mg/m2 46 hours, every 2 weeks). Follow up period was 8 weeks and survival follow up until death. Primary study objectives were to determine the dose-limiting toxicities (DLT) and maximum tolerated doses (MTD). Results:15 patients have been enrolled. 2 patients were omitted from study due to metastatic disease detected on day 1 post siG12D LODER implant imaging . Median age = 70 (range 52-85); male:female 8:7. Among 13 treated patients, the most frequent adverse events observed in the study were typically grade 1- 2 in severity; 4 patients experienced serious adverse events (SAE), one procedure related. No DLTs were observed. MTD was not reached. CT performed 8-10 weeks following the procedure showed stable disease in all patients. Reduction in tumor marker CA 19-9 was observed in 64% (7/11) of patients. The median survival of 13 patients was 16 months ( 8/13 patients still alive at analysis). Conclusions: The combination of siG12D LODER and chemotherapy is well tolerated. The combination has demonstrated promising efficacy in locally advanced PDAC with durable responses. Phamocodynamic endpoints are currently being examined in an expansion cohort in operable patients. A phase II randomized trial is planned in order to investigate efficacy of siG12D LODER in locally advanced non-operable PDAC. Clinical trial information: NCT01188785.

Purpose: To evaluate the efficacy and safety of the XEN63 Gel Stent in patients with open-angle glaucoma (OAG). Methods: Prospective, nonrandomized, open-label, not-controlled, and single center study conducted on OAG patients who underwent glaucoma surgery with the XEN63 gel stent. The main outcome measure was intraocular pressure (IOP). Secondary end-points were number of topical ocular hypotensive drugs, percentage of patients achieving an IOP reduction ⩾20%, and treatment-related adverse events. Results: Eleven eyes from 11 patients were treated with XEN 63. Mean (95% confidence interval, CI) age was 78.8 (73.7–85.9). Two eyes (18.2%) underwent XEN alone, while nine eyes (81.8%) underwent combined XEN + cataract extraction (phacoemulsification). The median (95% CI) IOP reduction was 17.7% (−13.3% to 34.9%). At the end of the study 9 (81.8%) eyes had an IOP ⩽ 18 mm Hg, six of them without treatment. Six (54.6%) eyes obtained an IOP reduction ⩾20%. Compared to baseline, there was a significant reduction in the number of ocular hypotensive drugs ( p = 0.0039). There were no treatment-related serious adverse events. Early postoperative complications included diplopia (1), blood in endothelium (2), ocular hypertension (1), corneal edema (1), folds in Descemet’s membrane (1), and contact between the implant and the iris (1). All the adverse events were successfully solved without sequalae. One eye required bleb needling. Conclusion: The XEN63 implant significantly reduced both IOP and the amount of ocular hypotensive medications while maintaining a good safety profile.

Abstract Background Recently, several studies have shown the high efficacy of Indigo naturalis (IN) in the induction therapy for ulcerative colitis (UC). However, the efficacy and safety in the maintenance therapy remain unclear. Thus, we performed this prospective study to investigate the efficacy and safety of IN for induction and maintenance therapy in patients with moderate to severe active UC. Methods We conducted a prospective uncontrolled open-label study at Kyushu university hospital. A total of 33 patients with moderate to severe active UC (clinical activity index (CAI) ≥8) received 2 g per day of IN for 52 weeks. We assessed CAI at week 0, 4, 8, 52, and Mayo endoscopic score (MES) was evaluated at weeks 0, 4, 52. We calculated the clinical remission (CAI ≤4) rate and mucosal healing (MES ≤1) rate at each point. Overall adverse events (AEs) during the follow-up were also estimated. Results Clinical remission rates at weeks 4, 8, and 52 were 67%, 76%, and 73%, respectively. Mucosal healing rates at weeks 4 and 52 were 48% and 70%. Seventeen patients experienced adverse events (AEs) during the follow-up. Seven severe AEs, including intussusceptions, acute severe colitis, infectious colitis, portal thrombosis, appendicitis, were observed in 4 patients. Conclusion Our prospective study indicated that IN was a promising option for induction and maintenance therapy in UC. However, possible AEs of IN should be paid attention.
