4-Week Multicenter, Randomized, Double-Blind, Parallel-Group, Vehicle-Controlled Safety and Efficacy Study of PUR 0110 (Thykamine™) Cream Applied Twice Daily in Mild-to-Moderate Atopic Dermatitis
A Phase 2, multicenter, double-blind, placebo control study evaluating the safety and efficacy of Thykamine in adult patient suffering of mild-to-moderate Atopic Dermatitis
A 2-Week Exploratory Randomized, Double-Blind, Parallel-Group, Dose-Ranging, Placebo-Controlled Safety, Tolerability, Biomarker and Efficacy Clinical Study of PUR 0110 Rectal Enema in Mild-to-Moderate Distal Ulcerative Colitis
PUR 0110 is a 100% natural novel investigational medicinal product that has been demonstrated in several in vitro and in vivo pharmacology studies to have potent anti-inflammatory, anti-oxidative and immunomodulatory effects. This exploratory Phase 2a study is a first-in-patient study to evaluate the safety, tolerability, biomarker effect and efficacy of PUR 0110 rectal enema in patients with active mild-to-moderate distal ulcerative colitis (UC).
The study is a multicenter, randomized, double-blind, parallel-group, dose-ranging, placebo-controlled study. To be eligible for inclusion into the study, patients must either be newly diagnosed or have on-going active mild-to-moderate distal ulcerative colitis of at least 3 months duration confirmed in either case by flexible sigmoidoscopy and biopsy at the Screening Visit. In addition, patients must have a modified Mayo score of ≥5 to ≤10 including a sigmoidoscopy inflammation grade and rectal bleeding scores of ≥2 each. Eligible patients will be randomly assigned to receive either PUR 0110 250 mg, 500 mg or 1000 mg or placebo rectal enema in a 1:1:1:1 ratio. Patients will self-administer the assigned study medication intrarectally once-daily at bedtime (10:00 p.m +/- 1 hour) for 2 weeks.
Patients will be evaluated for safety by adverse events, clinical laboratory tests, vital signs, physical examination, electrocardiogram (ECG), and concomitant medications. Efficacy evaluations will include the modified Mayo score, patient-defined response and remission, Investigator Assessment of Ulcerative Colitis Symptom Score, Inflammatory Bowel Disease Questionnaire (IBDQ), and biomarkers of inflammation, apoptosis and total cell death, lipid peroxidation and in vivo oxidative stress, and antioxidant defense mechanisms in plasma, serum, urine, feces and biopsy tissue. Patients will have a flexible sigmoidoscopy and biopsy 12 hours after the last dose of study medication.
A Randomized, Double-Blind, Parallel-Group, Single-Ascending Dose, Placebo-Controlled Safety and Tolerability Study of PUR 0110 Rectal Enema in Normal Healthy Volunteers
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.
