Switching From Reference Infliximab to Biosimilar CT-P13 Did Not Change Quality of Life in Stable Inflammatory Bowel Disease Patients.

Background: Quality of life (QoL) data for patients with inflammatory bowel disease switched from the reference infliximab to biosimilar CT-P13 is lacking. This study aims to demonstrate noninferiority for QoL and efficacy after switching.

Methods: OoL and clinical efficacy were measured prior to and after 2, 4, and 6 CT-P13 infusions.

Serum concentrations after switching from originator infliximab to the biosimilar CT-P13 in patients with quiescent inflammatory bowel disease (SECURE): an open-label, multicentre, phase 4 non-inferiority trial.

Background: Biological treatment of chronic inflammatory diseases has improved patient outcomes but increased health-care costs. Switching patients from originator infliximab to a biosimilar can reduce costs, but prospective data about pharmacokinetics and potential immunogenicity are scarce. We aimed to show that infliximab serum concentrations with biosimilar CT-P13 are non-inferior to those with originator infliximab after switching from originator infliximab in patients with inflammatory bowel disease.

Prolonged release oxycodone and naloxone treatment counteracts opioid-induced constipation in patients with severe pain compared to previous analgesic treatment.

Objective: Treatment with prolonged-release oxycodone/naloxone (PR OXN) has been shown to improve opioid induced constipation (OIC) in constipated patients. This publication reports on a real-life observational study investigating the efficacy of PR OXN with regard to bowel function in patients switching to PR OXN from WHO step 1, step 2 and step 3 opioids.

Methods: Patients with chronic pain experiencing insufficient pain relief and/or unacceptable side effects were switched to PR OXN and monitored in this observational study with respect to efficacy regarding bowel function and efficacy regarding pain relief in comparison with previous analgesic therapy.

The efficacy of standard laxative use for the prevention and treatment of opioid induced constipation during oxycodone use: a small Dutch observational pilot study.

Background: Dutch clinical guidelines recommend that a standard laxative treatment (SLT) should be prescribed concomitantly when starting opioid treatment to prevent opioid-induced constipation (OIC).

Methods: Clinical evidence for SLT in the treatment of OIC is lacking, therefore an observational pilot study was performed to explore the efficacy and tolerability of SLT on OIC in patients treated with the opioid oxycodone.

Results: Twenty-four patients (58% female, median (range) age 65 (39-92)) were included in this pilot study.

Treatment with prolonged-release oxycodone/naloxone improves pain relief and opioid-induced constipation compared with prolonged-release oxycodone in patients with chronic severe pain and laxative-refractory constipation.

Purpose: Laxative-refractory opioid-induced constipation (OIC) is defined as OIC despite using 2 laxatives with a different mechanism of action (based on the Anatomical Therapeutic Chemical Classification System level 4 term [contact laxatives, osmotically acting laxatives, softeners/emollients, enemas, and others]). OIC has a significant impact on the treatment and quality of life of patients with severe chronic pain. This noninterventional, observational, real-life study in Belgium investigated the efficacy of prolonged-release oxycodone/naloxone combination (PR OXN) treatment regarding pain relief and OIC compared with previous prolonged-release oxycodone (PR OXY) treatment for laxative-refractory OIC in daily clinical practice.

Fixed ratio (2:1) prolonged-release oxycodone/naloxone combination improves bowel function in patients with moderate-to-severe pain and opioid-induced constipation refractory to at least two classes of laxatives.

Objective: The effects of combined oxycodone/naloxone prolonged release tablets (OXN PR) were investigated in patients with moderate-to-severe chronic cancer-related or non-cancer pain. All patients had opioid-induced constipation (OIC) which persisted despite substantial laxative therapy.

Research Design And Methods: This pooled analysis included 75 patients with OIC at study entry that was refractory to at least two laxatives with different modes of action.

Yeast glycolytic oscillations that are not controlled by a single oscillophore: a new definition of oscillophore strength.

Biochemical oscillations, such as glycolytic oscillations, are often believed to be caused by a single so-called 'oscillophore'. The main characteristics of yeast glycolytic oscillations, such as frequency and amplitude, are however controlled by several enzymes. In this paper, we develop a method to quantify to which extent any enzyme determines the occurrence of oscillations.
