About this study

Official title: A Double-Blind, Placebo-Controlled, 4-Way Crossover Study to Evaluate the Pharmacokinetics and Pharmacodynamics at Two Dose Levels of SJP-001 in Comparison With Fexofenadine and Naproxen Administered in Conjunction With Alcohol.

This will be a double-blind, placebo-controlled study with a 4-way crossover design with subjects administered study drug (SJP-001), placebo, fexofenadine alone and naproxen alone on different study days, in conjunction with a quantity of alcohol estimated to be sufficient to produce a hangover the next day. The amount of alcohol may vary from subject to subject, however each subject will consume the same types and amounts of alcohol on each subsequent treatment day as consumed on the first.

Read the detailed description

At each of four treatment visits, each separated by a minimum 7-day washout (i.e., the treatment day followed by a minimum of 6 subsequent non-treatment days), subjects will be administered SJP-001, placebo, fexofenadine alone and naproxen alone. Subjects will be randomized equally to one of four treatment sequences, according to a schedule prepared prior to the start of the study. Treatments will be administered 15 minutes before the start of a maximum 3-hour interval during which subjects will drink their choice of a selection of alcoholic and non-alcohol beverages. The amount of alcohol consumed will be targeted to achieve a breath alcohol content (BrAC) of 0.08%, a level estimated to be sufficient to produce a hangover the following day.

  8. Pharmacodynamics (PD) of two different doses of SJP001 administered in conjunction with alcohol to healthy adult subjects- Multiple symptom hangover scores

    Multiple symptom hangover scores is a multi-value, multi-symptom scores derived from individual subjective self-reporting of a spectrum of hangover symptoms in terms of incidence and severity. (23 symptoms scored 0-10; 0=none, 10=worst)

    Measured: Day 1 to Day 23 post first dose administration

Secondary outcomes (5)
  1. PK characteristics of each drug by treatment group- Cmax (maximum plasma concentration)

    Drug to drug analysis Fexofenadine administered as SJP-001 with administration of fexofenadine alone, and the PK characteristics of naproxen administered as SJP-001with administration of naproxen alone.

  4. Overall hangover severity after administering SJP-001, after fexofenadine alone and after naproxen alone

    Single item scale and scores on a multi-symptom scale) will be analyzed and compared between treatments, including placebo, by 2-way (Treatment x Time) ANOVA, for each dose level.

    Measured: Day 1 to Day 23 post first dose administration

  5. Quantitative differences in symptom profiles by treatment.

    Number of participants experiencing treatment-emergent adverse events (TEAEs) in each treatment arm. Severity was assessed by the investigator as mild (awareness of sign/symptom but easily tolerated), moderate (enough discomfort to interfere with usual activity, may warrant intervention), or severe (incapacitating, inability to perform usual activities, significantly affects clinical status, warrants intervention). Causality was assessed as definitely related, possibly related, or unrelated to study drug.

    Measured: Day 1 to Day 23 post first dose administration

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Treatment A- Fexofenadine HCl 60mg, Treatment B- Naproxen sodium 220mg and Treatment C- SJP-001 280mg in people with Healthy, run by Sen-Jam Pharmaceutical at 1 site in Canada.

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 9 inclusion and 27 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 23 Mar 2026. 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 Canada. 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Pharmacokinetics (PK) of two different doses of SJP001 administered in conjunction with alcohol to healthy adult subjects- Cmax (Maximum plasma concentration) (time frame: Day 1 to Day 23 post first dose administration). The study lists 8 primary outcomes in all. 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 23 Mar 2026; AzTrials last refreshed its copy on 7 Nov 2026.
