Reduce Crohn's-Associated Diarrhea With Sodium Channel Therapy

Vanderbilt University Medical Center4 enrolled

Overview

Crohn's disease is an inflammatory disorder that can affect any part of the gastrointestinal (GI) tract. Some patients still experience persistent diarrhea or other symptoms such as abdominal pain even when their Crohn's disease is in remission. Diarrhea and/or abdominal pain that is not responsive to standard therapies can significantly affect a patient's quality of life and ability to work. The purpose of this study is to test the safety and effectiveness of the drug ranolazine in reducing Crohn's disease-associated diarrhea and other symptoms. Ranolazine is approved by the US Food \& Drug Administration (FDA) for chronic angina (a heart condition). This study is investigating if ranolazine could be used in the setting of Crohn's disease.

Inclusion Criteria: * Meet diagnostic criteria for Crohn's Disease with active diarrhea Either with active disease or in remission (as defined by endoscopic or radiographic findings) but experiencing symptoms (e.g., diarrhea, abdominal pain) * Have greater than three loose stools per day Exclusion Criteria: * Male and female subjects \<18 years of age * Significant change in medication including prednisone, antidepressant medications, or stimulants within the last 4 weeks a. Allowances include: Rectal hydrocortisone, rectal mesalamine, addition of prednisone (up to 20mg) for flares, etc. * Regular (daily) use of opioids or other drugs of abuse including heavy alcohol or marijuana use * Severe psychiatric disease including schizophrenia, psychosis, suicidal depression * Previous use of ranolazine within 2 months prior to enrollment * Prior use of ranolazine which was discontinued for safety or tolerability * Metabolic derangement defined as liver function tests \>3x upper limit of normal or severe renal disease defined as calculated creatinine clearance \<30 mL/min * Have liver cirrhosis * Concurrent use of CYP3A inhibitors, inducers, or substrates a. These may include: ketoconazole, itraconazole, nefazodone, nelfinavir, ritonavir, indinavir, and saquinavir, clarithromycin, or rifampin, rifapentine, phenobarbital, phenytoin, and St. John's Wort, digoxin. * A family history of (or congenital) long QT syndrome or known acquired QT interval prolongation * Inability or refusal to give informed consent for any reason including a diagnosis of dementia or cognitive impairment * Patients who are pregnant or breastfeeding * Patients who are enrolled in other investigational drug studies or who have taken investigational drugs within 30 days before enrollment * Other factors which in the opinion of the investigator could potentially impact the study outcomes (e.g., underlying disease, medications, history) or prevent the participant from completing the protocol (poor compliance or unpredictable schedule)

Outcomes

Primary Outcomes

Daily Number of Loose Stools

Daily number of loose stools will be collected directly from all subjects using MyCap.

Time frame: Baseline to 12 weeks

Secondary Outcomes

Crohn's Disease Activity Index (CDAI) Score

The Crohn's Disease Activity Index (CDAI) combines weighted scores of clinical and laboratory variables to estimate disease severity. The CDAI consists of eight variables, two of which are subjective, related to the disease, each weighted according to its ability to be predictive of disease activity. The absolute score ranges from 0 to 600. CDAI scores of less than 150 indicate a clinical remission and scores over 450 indicate severely active disease. Since blood draws will not be performed as part of this study, the hematocrit component of the CDAI will not be assessed.

Time frame: Baseline to 12 weeks

Harvey Bradshaw Index (HBI) Score

The Harvey-Bradshaw index (Harvey-Bradshaw Index - HBI) assesses the degree of illness (activity) in patients with Crohn's disease. The HBI consists of 5 items with a minimum score of 0 and a maximum attainable score depending on the number of stools the patient identifies per day. HBI scores \< 5 are defined as clinical remission, HBI between 5 and 7 as mild disease, HBI between 8 and 16 as moderate disease, and HBI \> 16 as severe disease.

Time frame: Baseline to Week 12

Short Inflammatory Bowel Disease Questionnaire (SIBDQ) Score

The SIBDQ is a 10-item questionnaire measuring quality of life in four domains: bowel symptoms, emotional health, systemic symptoms, and social function and is scored on a 7-point Likert scale from 1 (severe problem) to 7 (no problems at all). The absolute score ranges are from 10 (poor Health-related quality of life) to 70 (optimum Health-related quality of life).

Time frame: Baseline to 12 weeks

Patient Health Questionnaire (PHQ-9) Score

The PHQ-9 is a 9-item questionnaire that screens for the presence and severity of depression and can be used to make a depression diagnosis using DSM-IV criteria. The PHQ-9 is scored on a 3-point Likert scale from 0 (not at all) to 3 (nearly every day). The absolute score ranges are from 0 (none or minimal depression) to 27 (severe depression).
