Safety and efficacy of recombinant human interleukin 10 in chronic active Crohn's disease

AbstractBackground & Aims: Interleukin (IL)-10 is a cytokine with potent anti-inflammatory properties. We investigated the safety and efficacy of different doses of human recombinant (rhu)IL-10 in patients with Crohn's disease (CD). Methods: A prospective, multicenter, double-blind, placebo-controlled study was conducted in 329 therapy-refractory patients with CD. Clinical improvement was defined by a reduction of the Crohn's Disease Activity Index (CDAI) by 100 points or more and clinical remission by a decrease of the CDAI to Results: Subcutaneous treatment with rhuIL-10 over 28 days induced a fully reversible, dose-dependent decrease in hemoglobin and thrombocyte counts but no clinically significant side effects. No differences in the induction of remission were observed between rhuIL-10 groups (1 μg, 18% [9.6–29.2]; 4 μg, 20% [11.3–32.2]; 8 μg, 20% [11.1–31.8]; 20 μg, 28% [18–40.7]; and placebo, 18% [9.6–29.6]). Clinical improvement was observed in 46% (33.7–59) in the 8-μg/kg rhuIL-10 group in comparison with 27% (17–39.6) in patients taking placebo. Responders to rhuIL-10 showed inhibition of NF-κB p65 activation in contrast to nonresponders. Conclusions: Up to 8 μg/kg of rhuIL-10 was well tolerated. A tendency toward clinical improvement but not remission was observed in the 8-μg/kg dose group. Further studies should delineate which subgroups of patients with CD benefit from rhuIL-10 therapy.GASTROENTEROLOGY 2000;119:1461-147

Interleukin 10 reduces the incidence of pancreatitis after therapeutic endoscopic retrograde cholangiopancreatography.

BACKGROUND & AIMS: Prophylactic administration of interleukin (IL)-10 decreases the severity of experimental pancreatitis. Prevention of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis in humans is a unique model to study the potential role of IL-10 in this setting. METHODS: In a single-center, double-blind, randomized, placebo-controlled study, the effect of a single injection of 4 microg/kg (group 1) or 20 microg/kg (group 2) IL-10 was compared with that of placebo (group 0), all administered 30 minutes before therapeutic ERCP. The primary endpoint was the effect of IL-10 on serum levels of amylases and lipases measured 4, 24, and 48 hours after ERCP. The secondary objective was to evaluate changes in plasma cytokines (IL-6, IL-8, tumor necrosis factor) at the same time points and the incidence of acute pancreatitis in the 3 groups. Subjects undergoing a first therapeutic ERCP were eligible for inclusion. RESULTS: A total of 144 patients were included. Seven were excluded based on intention to treat (n = 1) or per protocol (n = 6). Forty-five, 48, and 44 patients remained in groups 0, 1, and 2, respectively. The 3 groups were comparable for age, sex, underlying disease, indication for treatment, type of treatment, and plasma levels of C-reactive protein (CRP), cytokines, and hydrolases at baseline. No significant difference was observed in CRP, cytokine, and hydrolase plasma levels after ERCP. Forty-three patients developed hyperhydrolasemia (18 in group 0, 14 in group 1, and 11 in group 2; P = 0.297), and 19 patients developed acute clinical pancreatitis (11 in group 0, 5 in group 1, 3 in group 2; P = 0.038). Two severe cases were observed in the placebo group. No mortality related to ERCP was observed. Logistic regression identified 3 independent risk factors for post-therapeutic ERCP pancreatitis: IL-10 administration (odds ratio [OR], 0.46; 95% confidence interval [95% CI], 0.22-0.96; P = 0.039), pancreatic sphincterotomy (OR, 5.04; 95% CI, 1.53-16.61; P = 0.008), and acinarization (OR, 8.19; 95% CI, 1.83-36.57; P = 0.006). CONCLUSIONS: A single intravenous dose of IL-10, given 30 minutes before the start of the procedure, independently reduces the incidence of post-therapeutic ERCP pancreatitis.Clinical TrialJournal ArticleRandomized Controlled TrialResearch Support, Non-U.S. Gov'tinfo:eu-repo/semantics/publishe

Recombinant human interleukin 10 in the treatment of patients with mild to moderately active Crohn's disease

Background & Aims: Interleukin 10 (IL-10) is an anti-inflammatory, immunomodulatory cytokine that regulates mucosal inflammation. This study evaluated the safety, tolerance, and efficacy of recombinant human IL-10 (rhuIL-10) for mild to moderately active Crohn's disease. Methods: We conducted a 24-week multicenter, prospective, randomized, double-blind, placebo-controlled, and sequential-escalating-dose study. Ninety-five patients with Crohn's Disease Activity Index of 200-350, not presently undergoing corticosteroid, mesalamine, or immunosuppressive therapy, were treated with subcutaneous rhuIL-10 (1, 5, 10, or 20 μg/kg) or placebo once daily for 28 consecutive days. Patients were followed up for 20 weeks after treatment. Evaluation of safety and tolerance was the first objective, and efficacy was the second objective. Results: Adverse effects were dose-related, mild-to-moderate in severity, and reversible. Asymptomatic and reversible anemia and thrombocytopenia were observed at higher doses. No withdrawal or delayed adverse effects were evident during 20 weeks of follow-up. At the end of treatment (day 29), intent-to-treat analysis showed that 23.5% (confidence interval [CI], 6.8%-49.9%) of patients receiving 5 μg/kg rhuIL-10 experienced clinical remission and endoscopic improvement; 0% (CI, 0%-14.8%) of patients in the placebo group did. Higher doses of recombinant human IL-10 were less effective than 5 μg/kg. No rhuIL-10 serum accumulation and no antibody against IL-10 were detected after 4 weeks. Conclusions: Subcutaneous rhuIL-10 administered daily for 28 days to patients with mild to moderately active Crohn's disease is safe, well-tolerated, and shows clinical and endoscopic improvement.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
