AJM300 is an orally active small-molecule antagonist of the α4 integrin subunit. We performed a randomized trial to investigate the efficacy and safety of AJM300 in patients with active ulcerative colitis (UC). ⋯ AJM300 was well tolerated and more effective than placebo in inducing clinical response, clinical remission, and mucosal healing in patients with moderately active UC.

Inflammation may contribute to the formation, maintenance, and expansion of cancer stem cells (CSCs), which have the capacity for self-renewal, differentiation, and resistance to cytotoxic agents. We investigated the effects of the inflammatory mediator prostaglandin E2 (PGE2) on colorectal CSC development and metastasis in mice and the correlation between levels of PGE2 and CSC markers in human colorectal cancer (CRC) specimens. ⋯ PGE2 induces CSC expansion by activating NF-κB, via EP4-PI3K and EP4-mitogen-activated protein kinase signaling, and promotes the formation of liver metastases in mice. The PGE2 signaling pathway therefore might be targeted therapeutically to slow CSC expansion and colorectal cancer progression.

Randomized Controlled Trial Multicenter Study
Diet low in FODMAPs reduces symptoms of irritable bowel syndrome as well as traditional dietary advice: a randomized controlled trial.
A diet with reduced content of fermentable short-chain carbohydrates (fermentable oligo-, di-, monosaccharides, and polyols [FODMAPs]) has been reported to be effective in the treatment of patients with irritable bowel syndrome (IBS). However, there is no evidence of its superiority to traditional dietary advice for these patients. We compared the effects of a diet low in FODMAPs with traditional dietary advice in a randomized controlled trial of patients with IBS. ⋯ A diet low in FODMAPs reduces IBS symptoms as well as traditional IBS dietary advice. Combining elements from these 2 strategies might further reduce symptoms of IBS. ClinicalTrials.gov ID NCT02107625.

We conducted an open-label, randomized, phase 3 trial to determine the efficacy and safety of sofosbuvir and ribavirin, with and without peginterferon-alfa, in treatment-experienced patients with cirrhosis and hepatitis C virus (HCV) genotype 2 infection and treatment-naïve or treatment-experienced patients with HCV genotype 3 infection. ⋯ Among patients with genotype 3 HCV infection, including a large proportion of treatment-experienced patients with cirrhosis, the combination of sofosbuvir, peginterferon, and ribavirin for 12 weeks produces high rates of SVR. Treatment-experienced patients with cirrhosis and genotype 2 HCV infection had high rates of SVR in all groups. EudraCT ID 2013-002641-11.

Multicenter Study
Efficacy of ledipasvir and sofosbuvir, with or without ribavirin, for 12 weeks in patients with HCV genotype 3 or 6 infection.
We performed a phase 2 clinical trial to evaluate the efficacy and safety of ledipasvir and sofosbuvir, with or without ribavirin, in patients infected with hepatitis C virus (HCV) genotype 3 or 6. ⋯ In an uncontrolled, open-label trial, high rates of SVR12 were achieved by patients with HCV genotype 3 infection who received 12 weeks of ledipasvir and sofosbuvir plus ribavirin, and by patients with HCV genotype 6 infection who received 12 weeks of sofosbuvir and ledipasvir without ribavirin. Current guidelines do not recommend the use of ledipasvir and sofosbuvir, with or without ribavirin, in patients with HCV genotype 3 infection. ClinicalTrials.gov Number: NCT01826981.
