Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion criteria

  • Able to provide written informed consent prior to any study procedures, and willing and able to comply with study procedures.
  • Diagnosis of chronic IDIOPATHIC constipation, including experiencing constipation for 12 or more weeks in the preceding 12 months (defined by Rome III criteria for Functional Constipation, but all patients must meet the modified criterion of a history of ≤4 average defecations per week)
  • Stable concomitant medications (no changes in regimen for at least 2 weeks prior to baseline period)
  • Body mass index of 18-40 kg/m2
  • Females must not be lactating or pregnant

Exclusion criteria

  • Unable/unwilling to provide informed consent or to comply with study procedures
  • Diagnosis of secondary constipation e.g. underlying general neurological disease such as Parkinsonism, multiple sclerosis, diseases associated with peripheral neuropathy, iatrogenic constipation
  • Structural or metabolic diseases that affect the GI system NOTE: Patients with clinical suspicion of upper or lower GI obstruction must have been evaluated per standard of care and obstruction ruled out before screening

  • Unable to withdraw the following medications 48 hours prior to baseline period and throughout the study (except as protocol defined rescue medications):

    • Medications that alter GI transit including laxatives, magnesium and aluminum containing antacids, prokinetics, erythromycin, narcotics, anti-cholinergics, tricyclic antidepressants, SNRI and newer antidepressants
    • Selective serotonin reuptake inhibitor (SSRI) antidepressants are permissible at low, stable doses
    • Analgesic drugs including opiates, NSAIDs and COX-2 inhibitors
    • GABAnergic agents
    • Benzodiazepines
  • NOTE: stable doses of thyroid replacement, estrogen replacement, low dose aspirin for cardioprotection, and birth control (but with adequate backup contraception as drug-interactions with birth control have not been conducted) are permissible
  • Drugs with a low therapeutic index, such as warfarin, digoxin, anti-seizure medications
  • History of surgery within 60 days of screening
  • Acute or chronic illness or history of illness, which in the opinion of Investigator, could pose threat/harm to the patient or obscure interpretation of laboratory test results or interpretation of study data such as frequent angina, Class III or IV congestive heart failure, moderate impairment of renal or hepatic function, poorly controlled diabetes, etc
  • History of hypersensitivity to mannitol (an ingredient of both active and placebo study medications)
  • Clinically significant abnormalities on screening laboratories or physical examination as determined by Investigator
  • Abnormal 12-lead electrocardiogram (ECG), including evidence of acute myocardial or subendocardial ischemia and clinically significant arrhythmias or conduction abnormalities (including prolonged QTc > 500 msec) or abnormal blood pressure at screening except minor deviations deemed to be of no clinical significance by Investigator
  • Acute GI illness within 48 hours of initiation of the baseline period
  • ALT or AST > 1.2 X upper limit of normal during screening
  • Females who are pregnant or breastfeeding
  • History of excessive alcohol use or substance abuse
  • Participation in an investigational clinical study within 30 days prior to dosing in the present study
  • Any other reason, which in the opinion of the Investigator, would confound proper interpretation of the study

Exclusion criteria at the end of the baseline period

  • In addition, patients will not be randomized into the double-blind treatment comparison if during the baseline period they:
  • used rescue medications such as laxatives, beyond those allowed by protocol
  • demonstrated lack of compliance
  • averaged more than 4 spontaneous bowel movements per week
  • Substudy patients only: did not demonstrate slow colonic transit at end of baseline period (GC 24 >2.4)
  • Women of child-bearing potential: positive pregnancy test

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description

Effect of RM-131 on colonic transit
Time Frame: End of 14 day Baseline and end of 14 day Treatment periods
Change from baseline colonic geometric center at 24 hours
End of 14 day Baseline and end of 14 day Treatment periods

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Safety and tolerability of RM-131

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
