About this study

Official title: Randomized, Double Blind, Placebo Controlled "First-in-human" Study To Assess the Safety and Tolerability of Single Ascending Oral Doses of PBF-677 ( 100 mg, 200 mg, 400 mg and 600 mg ) in Healthy Young Male Volunteers

The proposed trial a "Randomized, Double Blind, Placebo Controlled "first in-human" Study to Assess the Safety and Tolerability of Single Ascending Oral Doses of PBF-677 in Male Healthy Volunteers" (Protocol Code No:CUNFI-1509 EudraCT No:2015-003546-57) will be a single-centre, randomized, double-blind, dose escalation study without therapeutic benefit, in which PBF-677 will be administered as single, oral, ascending-dose to volunteers.

Up to four different rising doses (100 mg, 200 mg, 400 mg and 600 mg) will be tested in groups of 8 participants; in each dose level participants will be randomized to active drug or placebo in a 6:2 fashion. As this will be the first time that PBF-677 in going to be administered to humans, as a safety measure a stepwise drug administration will be performed in each cohort. The volunteers of each cohort will be divided in 3 blocks/subgroups: Initially, one volunteer will receive active drug (subgroup 1). After 48h of safety and tolerability assessment, a second subgroup of 3 volunteers will receive 2 active drug and 1 placebo and after further 48h of safety and tolerability assessments a third subgroup of 4 volunteers will receive 3 active drug and 1 placebo. After evaluation of safety, parameters of corresponding dose level the process will replicate one week afterwards in the following dosages.

The principal variable safety and tolerability of PBF-677 will be evaluated with physical records (Electrocardiogram (ECG), vital signs, blood chemistry and haematology, conducted before, during and after study course). Assessment of the pharmacokinetic profile (Maximum plasma concentration of the drug (peak) after single dose (Cmax),Time necessary to reach Cmax (tmax), Area under the time-concentration curve to "zero" to time "t" (AUC0t), and Elimination half-life (t1/2) of PBF-677 will be included as secondary variable.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Adverse events

    The occurrence of adverse events will be monitored through the complete study. Adverse events will be recorded with the following information: severity grade (mild, moderate, severe); suspected/unsuspected relationship to the study drug; duration (date and time of onset, defined as precisely as possible, and end date or if continuing at final exam)

    Measured: 1 week

Secondary outcomes (8)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PBF-677 in people with Glaucoma, run by Palobiofarma SL.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Adverse events (time frame: 1 week). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Dec 2018.
