Active clinical trials for "Opioid-Induced Constipation"

At least 30% of patients receiving methadone maintenance therapy (MMT) are suffering from constipation that often affects effectiveness of MMT and increases its impact on health care system. Existing treatments include several over-the-counter medications which do not target the pathobiological basis of opioid-induced constipation and have limited effectiveness. At the same time well-known medication, naloxone, was already shown to help with constipation in patients receiving methadone for chronic pain, but was never tried in patients receiving methadone for opioid dependence. This study is aimed to try naloxone for treatment of opioid-induced constipation in MMT settings. The investigators will enroll 20 patients receiving MMT and suffering from opioid-induced constipation. The study has a crossover design - all patients will receive one week of their regular methadone doses and one week of their regular methadone doses with naloxone added. Normal saline will be added to methadone-only formulations as placebo. Order of the weeks will be chosen randomly. Both subjects and investigators will be blinded to the study condition (i.e. whether naloxone or normal saline is added to methadone preparation on a given week). Primary hypothesis: Patients receiving combination of oral methadone/naloxone in ratio 50:1 will have less severe symptoms of constipation compared to those receiving methadone only. Secondary hypothesis: Addition of oral naloxone to methadone in a ratio 50:1 will not cause clinically significant opioid withdrawal symptoms.

The main purpose of this study is to assess how effective and tolerable the country specific clinical practice guidelines of SLTs are for UK, France and Sweden are. The main rationale behind this study is that well controlled comparisons of the various laxatives for the treatment of OIC are lacking. There is lack of evidence suggesting which laxative or combination of laxatives is optimal for managing OIC.

The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of TD-1211 in healthy subjects and activity in subjects with opioid-induced constipation (OIC).

The primary purpose of this study is to evaluate the efficacy and safety of lubiprostone administration in patients with Opioid-induced Bowel Dysfunction.

The purpose of this study is to evaluate the effect and safety of NKTR-118 treatment of opioid-induced constipation in patients with non-cancer-related pain over a 6-month period.

This is a double-blind, randomized, parallel group, dose ranging study of subcutaneous methylnaltrexone to be conducted in patients with advanced medical illness and poorly controlled opioid induced constipation. Patients will be randomized to one of three fixed dose levels of SC MNTX.

The primary purpose of the study is to evaluate the efficacy and safety of lubiprostone administration in subjects with Opioid-induced Bowel Dysfunction.

The purpose of this study is to evaluate the safety, tolerability and efficacy of ALKS 37 when administered daily for 4 weeks to adults with Opioid-induced Constipation (OIC).

A Single-Blind, Pilot Study to Determine the Tolerability and Safety of TD-1211 in Subjects with Opioid-Induced Constipation

The primary purpose of this study is to evaluate the safety, efficacy, and tolerability of subcutaneous (injection beneath the skin) MOA-728 versus placebo in adult Asian subjects with opioid-induced constipation associated with advanced illness (ie, a terminal illness such as incurable cancer or other end-stage disease) or chronic nonmalignant pain.
