Study summary

This is a 4-week pilot, multicenter, randomized, double-blinded placebo controlled trial of hydroxocobalamin and butyrate in ulcerative colitis (UC) that will occur in two phases. The main objectives of this study are to determine the capacity of hydroxocobalamin and butyrate to reduce calprotectin in those with inflammatory disease in UC to determine the safety and preferential dose of hydroxocobalamin with butyrate in UC.

Read the detailed description

The goal of this study is to determine the preferable dose of hydroxocobalamin in a 4-week pilot study in patients with UC and determine if this approach can reduce stool calprotectin. Before going forward with a larger efficacy trial, the investigators are first aiming to determine if the supplements/medications we are proposing to use are sufficient to reduce a biomarker. Consequently, this study will look at a more easily measurable biomarker to provide evidence that the dosing is sufficient.

This pilot study will be conducted to assess preferable dose of hydroxocobalamin based on reduction of calprotectin. The investigators aim to determine if this reduction is sustained over time and is correlated to changes in clinical disease activity.

Study arms

  • Active comparator
    Hydroxocobalamin with Butyrate

    Subjects enrolled will take hydroxocobalamin capsules twice daily for 4 weeks. All subjects will take an oral butyrate dose of 120 mg twice daily for 4 weeks.

    Drug: Hydroxocobalamin with Butyrate

  • Placebo comparator
    Placebo with Butyrate

    Subjects enrolled will take placebo capsules twice daily for 4 weeks. All subjects will take an oral butyrate dose of 120 mg twice daily for 4 weeks.

    Drug: Placebo with Butyrate

Interventions

  • DrugHydroxocobalamin with Butyrate

    In phase 1, patients will take hydroxocobalamin at 1g daily for four weeks. This will be in the form of 1 500mg capsule twice a day. Butyrate will be 240 mg daily in a divided dose (120 mg twice daily) which is 5 pills twice a day. In phase 2, the dose of hydroxocobalamin will be increased to 2g daily (1g twice a day) for four weeks pending FDA approval. Butyrate will remain at 240 mg daily in a divided dose (120 mg twice daily) which is 5 pills twice a day. Patients will undergo flexible sigmoidoscopy at baseline and at week four in phase 2.

  • DrugPlacebo with Butyrate

    In phase 1, patients will take 1 placebo capsule twice a day. Butyrate will be taken at 240 mg daily in a divided dose (120 mg twice daily) which is 5 pills twice a day. In phase 2, patients will take 2 placebo capsules twice a day, along with butyrate at 240 mg daily in a divided dose (120 mg twice daily) which is 5 pills twice a day.

What researchers measure

Primary outcomes

  1. Change from Baseline fecal calprotectin at week 4

    Proportion of patients with reductions in fecal calprotectin

    Time frame: At baseline and at week 4

  2. Incidence of Treatment-Emergent Adverse Events (AE) as assessed by Common Terminology Criteria for Adverse Events (CTCAE)

    CTCAE are a set of criteria for the standardized classification of adverse effects of drugs used in clinical trials. It uses a range of grades from 1 to 5, where 1 is mild and 5 is life-threatening.The number of AE and grade of each AE will be measured for the duration of the trial.

    Time frame: Up to 4 weeks

  3. Clinical Symptoms assessed by Simple Clinical Colitis Activity Index (SCCAI)

    The SCCAI is an index to measure disease activity in patients with UC. SCCAI will be used throughout the trial to measure clinical UC symptoms of participants.

    Time frame: Up to 4 weeks

Secondary outcomes

  1. Assessment of urinary and plasma nitrite, nitrate levels and nitrosothiol levels

    Comparison of levels at baseline to week 1-2 and week 4

    Time frame: At week 1-2 and at week 4

  2. Normalization of fecal calprotectin below the upper limit of normal

    Assessment in number of patients whose fecal calprotectin normalizes

    Time frame: At the end of week 4

  3. Reduction of Mayo Score (Phase 2)

    Proportion of patients with a reduction in Mayo Score

    Time frame: At the end of week 4

  4. Correlation between urinary and plasma nitrite, nitrate or nitrosothiol levels and fecal calprotectin

    Comparison of biochemical levels with calprotectin

    Time frame: Up to 4 weeks
