Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 55 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Understanding and accepting the study procedures and signing the informed consent.
  • Male and female volunteers aged 18 to 55 years. No fixed sex ratio has been established.
  • Clinical history and physical examination demonstrating no organic or psychiatric disorders.
  • The ECG and general blood and urine laboratory tests performed before the study should be within normal ranges. Minor or occasional changes from normal ranges are accepted if, in the investigator's opinion, considering the current state of the art, they are not clinically significant, are not life-threatening for the subjects and do not interfere with the product assessment. These changes and their non-relevance will be justified in writing specifically.
  • The body mass index (BMI=weigh/height2) will range from 19 to 25 kg/m2, and the weight from 50 to 100 kg. 25-27 could be accepted.
  • Women with regular menstrual cycle of 26-32 days.
  • Subjects socially drinking and who had ingested wine at least once.

Who cannot join

  • Not meeting the inclusion criteria.
  • History or clinical evidence of gastrointestinal, liver, renal or other disorders which may lead to suspecting a disorder in drug absorption, distribution, metabolism or excretion, or that suggest gastrointestinal irritation due to drugs.
  • History or clinical evidence of psychiatric disorders, alcoholism, drug abuse, or regular use of psychoactive drugs.
  • Blood donation in the previous 8 weeks or participation in other clinical trials with drugs in the previous 12 weeks.
  • Having suffered any organic disease or major surgery in the three months prior to the study start.
  • Subjects with intolerance or serious adverse reactions to ethanol.
Show all 19Show fewer
  • Regular use of any drug in the month prior to the study sessions, except for vitamins or diet supplements, that, in the opinion of the principal investigator or co-investigators designated by him, do not involve a risk for the subject and do not interfere with the study objectives. In this case they should be discontinued from one week before the experimental sessions to the end of them. The treatment with single or limited doses of symptomatic medicinal products in the week prior to the study sessions will not be a reason for exclusion if it is calculated that it has been cleared completely the day of the experimental session.
  • Taking more than 20 g of alcohol a day in women and more than 30 g in men.
  • Taking more than 5 coffees, teas, cola drinks or other stimulating drinks or with xanthines daily in the 3 months prior to the study start.
  • Subjects unable to understand the nature, consequences of the study and the procedures requested to be followed.
  • Smokers or ex-smokers of less than one year.
  • Subjects with positive serology to Hepatitis B, C or HIV.
  • Pregnant or nursing women or positive pregnancy test in urine. Women not undertaking to follow reliable contraceptive measures during the study (such as abstinence, hormonal contraceptives, intrauterine devices, double-barrier methods or vasectomised partner).
  • Women with amenorrhea or premenstrual syndrome of moderate or severe intensity.
  • Nonsteroidal anti-inflammatory drugs, antioxidants or vitamins consumption in the last 2 weeks.
  • Total cholesterol >6.00 mmol/l (240 mg/dl) or triglycerides >2.26 mmol/l (200 mg/dl).
  • Vegetarians or subjects following aberrant diets.
  • Physical exercise of >2h/day or >3000 kcal /week.
  • To be eligible, the subjects must agree to follow a poor polyphenols diet in the 72 hours prior to the start of each session and until 24 hours after.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Ethanol, Water and Alcoholized wine in people with Contribution of Wine Components in Hydroxytyrosol Formation, run by Parc de Salut Mar at 1 site in Spain.

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 7 inclusion and 19 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 24 Jul 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Hydroxytyrosol biological fluids concentrations (time frame: 0-24h after administration). 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 24 Jul 2014; AzTrials last refreshed its copy on 7 Nov 2026.
