A Study to Assess the Safety and Tolerability of PUR 0110 Rectal Enema in Normal Healthy Volunteers

Germany24 participantsStarted 2009-06

Plain-language summary

This is a first-in-man study of a novel investigational botanical drug complex, PUR 0110 rectal enema, that has been shown to have potent anti-inflammatory, antioxidant and immunomodulatory effects following in vitro and in vivo pharmacology studies, to assess the safety and tolerability of sequential single-ascending doses in normal healthy volunteers and to determine the maximum tolerated dose (MTD). As a tertiary objective, the study will also investigate the presence of specific pharmacokinetic markers following the administration of single-dose PUR 0110 at each dose level. The study is designed as a single-center, randomized, double-blind, parallel-group, sequential single-ascending dose, placebo-controlled safety, tolerability and pharmacokinetic study of PUR 0110 rectal enema in 24 normal healthy male volunteers. Eligible subjects will be randomly assigned to 4 Cohorts of 6 subjects each to receive active drug (PUR 0110 Enema) or placebo enema as follows: 187.5 mg/60 g - Cohort 1, 375 mg/60 g - Cohort 2, 750 mg/60 g - Cohort 3 or 1500 mg/60 g - Cohort 4. Within each Cohort, subjects will be randomized in a 2:1 ratio to receive either active treatment (PUR 0110 enema; n = 4) or placebo enema (n = 2). Each subject will receive only 1 dose of assigned study medication and dosing of subjects within each cohort will also be by sequential inclusion.

Inclusion Criteria: * Healthy adult non-smoking male volunteers between the ages of 18 to 55 years, inclusive. * Must provide a voluntary written informed consent prior to initiation of screening, must be capable of following the verbal and written study instructions, and be able to commit to any confinements and return visits during the entire period of the study. * Must have a body mass index (BMI) that is within 18 to 30 kg/m2 on the BMI Chart. * Must have a normal digital rectal examination at screening. * Must have normal colonic and rectal mucosa at the baseline flexible sigmoidoscopy (i.e., no bleeding, inflammation, edema, ulceration or other abnormal finding). * Must have no clinically significant abnormal findings in their medical history, physical examination or clinical laboratory test results. Exclusion Criteria: * History or presence of clinically significant cardiovascular, pulmonary, hepatic, renal, hematological, gastrointestinal, endocrine, immunologic, dermatological, neurological, or psychiatric disease. * History of allergic reaction or hypersensitivity to spinach, spinach tablet, spinach powder or spinach extract; and to latex, molds and mushrooms. * Subjects with abnormal digital rectal examination at screening * Subjects with abnormal colonic and rectal mucosa at the baseline flexible sigmoidoscopy i.e., have bleeding, inflammation, edema or ulceration or other abnormal finding. * Subjects who used NSAIDs within 14 days prior to dosing. * History of…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
