Outcomes

Primary Outcome Measures

Number of subjects with treatment-related adverse events as assessed by CTCAE v4.03"
Adverse events will be assessed according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03. If

Secondary Outcome Measures

Effect of PBF-677 on Faecal calprotectin levels
Calprotectin levels in stools is a validated biomarker of the severity of the disease. A decrease in the calprotectin levels under 50 mg/Kg is associated with the remission of the disease flare.
Effect of PBF-677 on Ulcerative Colitis activity
The assessment Will be based on the Partial Mayo Scoring Index that sum and score the following ítems: Stool Frequency (based on the past 3 days) Rectal Bleeding (based on the past 3 days) Physician's Global Assessment The scoring range is as follow: Remission = 0-1 Mild Disease = 2-4 Moderate Disease = 5-6 Severe Disease =7-9
Pharmacokinetic PBF-677 peak concentration in plasma
The parameter will be calculated from plasma samples collected at days 1 and 14 after drug administration. It will consist in the maximum plasma concentration (ng/mL) of PBF-677 observed after administration
Pharmacokinetic Time to PBF-677 peak concentration in plasma "Tmax"
The parameter will be calculated from plasma samples collected at days 1 and 14 after drug administration.It will consist in the time (in minutes) to reach the maximum "PBF-677" concentration in plasma samples of patients after oral administration of PBF-677.
Pharmacokinetic Area under curve (AUC) of PBF-677 in plasma
The parameter will be calculated from plasma samples collected at days 1 and 14 after drug administration. It will consist in the area under the concentration-time curve from zero up to ∞ with extrapolation of the terminal phase. "AUC(0-inf)" will be given in Amount·time/ volume units
Pharmacokinetic Ctrough plasma concentration of PBF-677
Trough plasma concentration (measured concentration at the end of a dosing interval at steady state [taken directly before next administration])

5. Study Description

Brief Summary
This is a Phase IIa (proof of concept), randomized, double blind, placebo-controlled, multicentre clinical trial to evaluate the safety and efficacy of daily PBF-677 oral treatment during 28 days in Ulcerative colitis (UC) patients who are not receiving immunosuppressants and present mild-to-moderate activity of the disease. Enrolled patients would receive standard high doses of 5-ASA (4g), according to current clinical guidelines, and are randomized to receive also PBF-677 or placebo.
Detailed Description
This Proof-of-concept clinical trial is carefully designed to establish the safety profile of PBF-677 over 28 days in mild to moderate ulcerative colitis population and explore the relationship between the 200 mg PBF-677 dose and induction of remission, according to clinical parameters (Partial Mayo Score) and a faecal surrogate biomarker of mucosal inflammation (Calprotectin). The trial also will explore the PBF-677 pharmacokinetics (PK) profile during 28 days of administration. This small-scale study has been designed to detect a signal that PBF-677 is safe and active on decreasing levels of faecal calprotectin, as well as preliminary evidence of ameliorate the Partial Mayo Clinical Score in colitis patients who are in flare of the disease. The Population Under Study will be: Around 30 subjects. Adults (18-75 years old) non-immunosuppressed patients with mild to moderate active ulcerative colitis disease.
