Pregnancy Outcomes Reported During the 13-Year TREAT Registry: A Descriptive Report.

OBJECTIVES: We described pregnancy outcomes in Crohn's disease (CD) patients enrolled in the TREAT Registry who received infliximab before, or during pregnancy and those not treated with infliximab or any biologic agent. METHODS: In the TREAT Registry (1999-2012), pregnancy outcomes were analyzed from maternal and paternal patients exposed to infliximab ≤365 days (gestational exposure), >365 days (pre-gestational exposure) of pregnancy outcome or without infliximab exposure (non-biologic exposed). "Healthy infants" were defined as those with no congenital abnormalities, neonatal complications (e.g., jaundice, prematurity, heart murmur, cortical vision/fine motor delay, cardiac failure, hemophilia, or torticollis), prolonged hospitalization, or those who received no special treatment. Disease activity and concomitant medications were also evaluated. RESULTS: Overall, 92.3% (324/351) of pregnancies had known outcomes. The majority of both maternal pregnancies (92.6, 91.2, and 87.8%) and partner outcomes (92.7, 93.8, and 91.7%) resulted in live births of healthy infants across gestational, pre-gestational, and non-biologic exposure groups, respectively. Among these, rates of neonatal complications were low for both maternal (6.2, 7.0, and 8.5%), and partner outcomes (4.9, 0, and 0%) in gestational, pre-gestational, and non-biologic exposure groups, respectively. Among maternal pregnancies, numerically higher rates of spontaneous abortions were observed for the gestational exposure group than for the pre-gestational or non-biologic exposed groups. CONCLUSIONS: The clinical condition of infants born to women with gestational infliximab exposure was similar to those without exposure. Although a lower live birth rate was reported among infliximab-exposed women, these patients had more severe CD and were more likely to have been exposed to immunosuppressives.

Infliximab for Crohn's Disease: More Than 13 Years of Real-world Experience.

Background: The purpose of this study was to compare the long-term safety of infliximab and nonbiologic agents as Crohn's disease (CD) therapy. Methods: Patients with CD were prospectively evaluated in this large, observational registry. Results: Patients (n = 6273) participated in this observational registry from July 1999 through March 2012; 3440 (54.8%) received infliximab (20,971 patient-years), and 2833 (45.2%) received other treatments only (14,806 patient-years). Overall, 59,875 infliximab infusions were administered (80%, 5 mg/kg); 3006 (89.9%) patients received ≥2 infusions. Adverse events (AEs), most commonly those related to CD (eg, abdominal pain, diarrhea), and serious AEs occurred at a higher rate among infliximab-treated patients. Mortality (0.57/100 patient-years, 0.67/100 patient-years) and malignancy rates (0.69/100 patient-years, 0.71/100 patient-years) for infliximab-treated and other-treatments-only patients, respectively, were generally similar. Serious infection rates were higher for infliximab-treated (2.15/100 patient-years) than other-treatments-only patients (0.86/100 patient-years). Infliximab dose was not associated with mortality or serious infection. An increased risk of serious infection was observed with age (>52 years vs ≤30 years) when examined in infliximab-treated patients. Nonserious cerebrovascular accidents (13 events, 0.06/100 patient-years; 5 events, 0.03/100 patient-years) and pulmonary embolisms (11 events, 0.05/100 patient-years; 4 events 0.03/100 patient-years) also occurred at higher rates among infliximab-treated patients than other-treatments-only patients. Conclusions: Through more than 13 years of registry experience and an overall median duration of patient follow-up >6 years, mortality was similar between the infliximab-treated and other-treatments-only groups. These final cumulative results are representative of real-world experience among infliximab-treated patients with CD and are consistent with the known risks of disease activity and tumor necrosis factor antagonist therapy.

Nitroglycerin 0.4% ointment vs placebo in the treatment of pain resulting from chronic anal fissure: a randomized, double-blind, placebo-controlled study.

BACKGROUND: Complications of chronic anal fissure (CAF) treatments are prompting interest in lower-risk therapies. This study was conducted to compare nitroglycerin (NTG) 0.4% ointment with placebo for pain associated with CAF. METHODS: In this randomized, double-blind, placebo-controlled trial, patients with one CAF and moderate-to-severe pain (≥50 mm on a 100 mm visual analog scale [VAS]) received 375 mg NTG 0.4% (1.5 mg active ingredient) or 375 mg placebo ointment applied anally every 12 hours for 21 days. The primary end point was change from baseline VAS score in 24-hour pain averaged over days 14-18. Review of data from patients who withdrew early was blinded to treatment. To control for the confounding effects of analgesics, all patients received 650 mg acetaminophen for headache prophylaxis before each application. RESULTS: A total of 247 patients were enrolled (NTG, n = 123; placebo, n = 124). The prespecified baseline observation carried forward (BOCF) analysis found no significant difference between groups; however, a last observation carried forward (LOCF) analysis showed a significant advantage for NTG. A post hoc analysis (LOCF/BOCF hybrid) demonstrated a significant adjusted mean difference of -7.0 mm in favor of NTG 0.4% (95% CI -13.6, -0.4; P = .038). Headache was the most common adverse event in the NTG (69.9%) and placebo (47.6%) groups. CONCLUSIONS: This was the first placebo-controlled study that also controlled for the confounding effects of analgesics used to treat NTG-induced headache. In patients with moderate-to-severe CAF pain, NTG 0.4% ointment effectively reduced CAF pain compared with placebo. TRIAL REGISTRATION: ClinicalTrials.gov, NCT00522041.

Strategies in maintenance for patients receiving long-term therapy (SIMPLE): a study of MMX mesalamine for the long-term maintenance of quiescent ulcerative colitis.

BACKGROUND: This was a phase IV, multicenter, open-label, 12-14-month study to assess clinical recurrence in patients with ulcerative colitis (UC) who received maintenance treatment with MMX Multi Matrix System (MMX) mesalamine. A secondary outcome was the relationship between long-term efficacy and adherence. METHODS: Patients with quiescent UC (no rectal bleeding; 0-1 bowel movements more than normal per day) were enrolled directly into a 12-month maintenance phase of the study during which they received MMX mesalamine 2.4 g/day given once daily (QD). Patients with active, mild-to-moderate UC at screening were enrolled into a 2-month acute phase; those who achieved quiescence could continue into the maintenance phase. The primary endpoint was clinical recurrence at Month 6. RESULTS: Of the 290 patients enrolled, 208 entered the maintenance phase; 152 directly and 56 via the acute phase. Following 6 and 12 months of treatment, 76.5% and 64.4% of evaluable patients, respectively, were recurrence-free. The majority of evaluable patients at Month 6 (81.6%) and Month 12 (79.4%) in the maintenance phase were ≥ 80% adherent to MMX mesalamine. At Month 6, clinical recurrence was observed in 20.6% of patients who were ≥ 80% adherent and 36.1% of patients with <80% adherence (P = 0.05 [post-hoc chi-square analysis]); 31.2% and 52.5% at Month 12 (P = 0.01 [post-hoc chi-square analysis]). CONCLUSIONS: MMX mesalamine 2.4 g/day QD is effective for maintaining quiescence in patients with UC. Furthermore, adherence to prescribed treatment yielded lower rates of clinical recurrence. Continued education regarding the importance of long-term 5-aminosalicylic acid therapy is warranted.

5-ASA Dose-Response: Maximizing Efficacy and Adherence.

Mesalamine (5-aminosalicylic acid; 5-ASA) represents the cornerstone of first-line therapy for mild-to-moderate ulcerative colitis (UC). Current guidelines suggest that the combination of oral and rectal therapies provide optimal symptom resolution and effectively maintain remission in the majority of these patients. Although effective, most oral 5-ASA formulations have a high pill burden and rectal therapies are associated with low adherence. Recent research has examined patterns of compliance, as well as the efficacy of different dose levels of 5-ASA in terms of symptom resolution, the maintenance of remission, and improvements in quality of life. The ASCEND I, II, and III trials found that doses of 4.8 g/day are more effective than 2.4 g/day doses in patients with moderate disease, those with previous steroid use, and those with a history of multiple medications. The benefits of effective long-term 5-ASA therapy include the avoidance of more costly and potentially toxic drugs (such as corticosteroids and biologic therapies), as well as improvements in quality of life, reductions in the need for future colectomy, and a lower risk of developing colorectal cancer.

Once-daily dosing of delayed-release oral mesalamine (400-mg tablet) is as effective as twice-daily dosing for maintenance of remission of ulcerative colitis.

BACKGROUND & AIMS: The practice of dosing mesalamines in divided doses for the treatment of ulcerative colitis (UC) began with sulfasalazine and was driven by sulfapyridine toxicity. This convention and the assumption that dosing multiple times a day is necessary to treat UC had not been challenged until recently. This study was conducted to determine the efficacy and safety of once-daily dosing of delayed-release mesalamine (Asacol 400-mg tablets) compared with twice-daily dosing for maintaining remission in UC patients. METHODS: A multicenter, randomized, investigator-blinded, 12-month, active-control trial was conducted to assess the noninferiority of delayed-release mesalamine 1.6-2.4 g/day administered once daily compared with twice daily in patients with mild-to-moderate UC currently in clinical remission. The primary end point was maintenance of clinical remission at month 6. RESULTS: A total of 1023 patients were randomized and dosed. The primary objective of noninferiority was met. At month 6, 90.5% of patients receiving once-daily dosing had maintained clinical remission, compared with 91.8% of patients receiving twice-daily dosing (95% confidence interval for twice daily - once daily, -2.3 to 4.9). At month 12, 85.4% of patients receiving once-daily dosing had maintained clinical remission, compared with 85.4% of patients receiving twice-daily dosing (95% confidence interval for twice daily - once daily, -4.6 to 4.7). Both regimens had low rates of withdrawals as a result of adverse events and serious adverse events. CONCLUSIONS: Once-daily dosing of delayed-release mesalamine at doses of 1.6-2.4 g/day was shown to be as effective as twice-daily dosing for maintenance of clinical remission in patients with UC.

The effects of oral pancreatic enzymes (Creon 10 capsule) on steatorrhea: a multicenter, placebo-controlled, parallel group trial in subjects with chronic pancreatitis.

OBJECTIVES: Creon 10 Minimicrospheres is an enteric-coated, delayed-release pancrelipase preparation designed to deliver active pancreatic enzymes to the small intestine. The primary objective of this study was to compare the effect of Creon 10 with placebo in the control of steatorrhea in chronic pancreatitis patients. Secondary objectives included evaluation of stool parameters and global improvement of symptoms scales. METHODS: The study was a randomized, double-blind, placebo-controlled, 2-week trial. After a placebo run-in ("washout") phase, the effect on coefficient of fat absorption (%), daily fat excretion before and after treatment, and stool frequency and consistency were assessed. RESULTS: In Creon 10-treated subjects, the change in mean coefficient of fat absorption (%) from run-in to double-blind phase was significantly higher compared with placebo-treated subjects (+36.7 vs. +12.1, P = 0.0185). Stool consistency improved significantly more with Creon 10 than with placebo (P = 0.0102) resulting in more subjects with formed stool; stool frequency decreased significantly more with Creon 10 than with placebo (P = 0.0015) from 10.8 during placebo run-in to 5.2 stools per day during double-blind treatment; and daily mean fat excretion in stool decreased significantly more (-56.5 vs. -11.4 g/d, P = 0.0181) in Creon 10-treated subjects compared with placebo-treated subjects. Global disease symptom scores showed greater improvement for both physicians and subjects in the Creon 10 group relative to those receiving placebo. Between treatment difference reached statistical significance for Creon 10 (P = 0.0435) for physician score and showed a trend (P = 0.0634) favoring Creon for subject score. CONCLUSIONS: This randomized, placebo-controlled trial found that Creon 10 treatment controlled steatorrhea, as reflected in reduced fat excretion, decreased stool frequency and improved stool consistency. Creon 10 treatment was safe and well tolerated.

Pilot feasibility studies of leukocytapheresis with the Adacolumn Apheresis System in patients with active ulcerative colitis or Crohn disease.

GOALS: Two uncontrolled, multicenter feasibility studies evaluated safety and pilot efficacy of selective granulocyte and monocyte adsorption apheresis (GMA) with the Adacolumn Apheresis System for treatment of moderate-to-severe ulcerative colitis (UC) and Crohn disease (CD) patients refractory/intolerant to conventional pharmacologic therapy. BACKGROUND: Patients with UC and CD, characterized by elevations in peripheral blood granulocytes, monocytes/macrophages, and proinflammatory mediators, may benefit from reductions in activated granulocytes and monocytes by selective apheresis. METHODS: Patients underwent weekly Adacolumn sessions for 5 weeks. Pilot efficacy assessments used disease activity index (DAI) for UC (0-12) or CD activity index (CDAI; 0-600) for CD. RESULTS: Eleven of 15 UC patients completed all 5 treatments. Mean DAI scores fell from 8.4+/-1.3 (baseline) to 5.2+/-2.9 (week 7). Five patients had DAI reductions of > or = 3 points at week 7. Fourteen of 15 CD patients completed all 5 treatments. Mean CDAI scores fell from 308.0+/-76.5 (baseline) to 200.6+/-117.4 (week 7). Nine CD patients responded (CDAI reductions > or = 70 points) at week 7. Remission (CDAI score < or = 150 at week 7) was observed in 6 patients. There were no device-related serious adverse effects. CONCLUSIONS: Treatment with Adacolumn may be feasible and effective in patients with moderate-to-severe refractory inflammatory bowel disease. Larger sham-controlled studies are ongoing.

Scheduled maintenance treatment with infliximab is superior to episodic treatment for the healing of mucosal ulceration associated with Crohn's disease.

BACKGROUND: The endoscopic substudy of the ACCENT I (A Crohn's Disease Clinical Trial Evaluating Infliximab in a New Long-term Treatment Regimen) Crohn's disease trial examined the effects of infliximab on mucosal inflammation and mucosal healing, and assessed their impact on outcomes. DESIGN: ACCENT I was a randomized, double-blind, parallel group study. SETTING: This study took place at multiple centers in North America, Europe, and Israel. MAIN OUTCOME MEASUREMENTS: Ileocolonoscopic examinations were performed at weeks 0, 10, and 54. Complete mucosal healing was defined as the absence of all mucosal ulcerations. The end point of principal interest was the proportion of patients randomized as responders with mucosal healing at week 10. The proportion of responders who demonstrated mucosal healing at week 54 or at both weeks 10 and 54 is also summarized. Changes in Crohn's disease endoscopic index of severity (CDEIS) scores from baseline to week 10 and 54 were calculated for all patients in this substudy. RESULTS: Complete mucosal healing by week 10 occurred in significantly more week 2 responders who had received 3 doses of infliximab compared with a single dose (31% vs. 0%, p = 0.010). A significantly higher proportion of week 2 responders in the combined scheduled maintenance group had complete mucosal healing at week 54 compared with the episodic group (50% vs. 7%, p = 0.007). The results for all patients are consistent with those for week 2 responders only. Significantly greater improvement in the CDEIS occurred with scheduled maintenance compared with episodic treatment at week 10 (p
