About this study

Official title: Characterisation of Relative Bioavailability of GLA-015 in Comparison With an Oily Cannabidiol Solution (NRF 22.10) - a Multiple Dose, Randomised, 2-period Crossover-trial With Twice Daily Administration in Healthy Adult Male and Female Subjects

Glatt Pharmaceutical Services GmbH \& Co. KG is developing a new CBD granules formulation (GLA-015 / Cannabidiol 1500 mg 29,7% w/w GRA BLD P) which is intended to be used in the treatment of the new Coronavirus disease 2019 (COVID-19). Due to its enhanced solubility the new product is expected to show increased bioavailability, reduced variability especially in the fasted state and better robustness towards food interaction compared to oil-based cannabidiol solutions.

The aim of the present clinical trial is the characterisation of maximum systemic exposure of CBD and its active metabolite 7-OH-CBD of the newly developed Test product in the estimated target effective dose for treatment of COVID-19 as well as the comparison of its systemic bioavailability to CBD administered as oily solution.

Comparison of maximum systemic exposure of Test vs. Reference will be performed under steady state conditions with twice daily intake after a light meal over 7 consecutive days.

Read the detailed description

This single centre, open-label, randomised (order of treatments), balanced, multiple dose trial will be performed in a 2-period, 2-sequence-crossover design with direct switch-over. Eighteen (18) healthy subjects of both sexes (balanced distribution intended, but minimum 40% of each sex) are intended to be randomised.

The IMPs will be administered after a light meal as single oral doses of 1500 mg cannabidiol (i.e. 5.051 g granules of Test to be dispersed in water or 15 ml solution of Reference) twice daily (i.e. every 12 h) over 7 consecutive days.

Blood sampling will be performed after the 13th administration over 24 h, thereby including the 14th administration, in order to characterise pharmacokinetic parameters after multiple dosing over a whole day interval.

Comparison of maximum systemic exposure of Test vs. Reference will be performed under steady state conditions by means of AUC144-168,ss, Cmax,144-168,ss, and Cmin,144-168,ss of CBD and 7-OH-CBD.

The clinical trial will be performed as a cross-over investigation with intra-individual comparison, thus reducing variability of the pharmacokinetic parameters, which is supposed to be higher between subjects than within an individual subject.

What is being measured

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

  1. Comparison of relative bioavailability of Test vs. Reference after multiple dose administration after a light meal determined by use of AUC144-168,ss of cannabidiol

    AUC144-168,ss = partial area under the concentration vs. time curve over both dosing intervals on PK profiling day (i.e. starting with the morning dose on study day 7 to 12 h after the evening dose on study day 7), calculated by means of the linear up/log down method (linear trapezoidal rule for increases in concentration/logarithmic trapezoidal rule for decreases in concentrations)

    Measured: 24 hours

  2. Comparison of relative bioavailability of Test vs. Reference after multiple dose administration after a light meal determined by use of Cmax,144-168,ss of cannabidiol

    Cmax,144-168,ss = observed maximum concentration over both dosing intervals on PK profiling day (i.e. starting with the morning dose on study day 7 to 12 h after the evening dose on study day 7), considering scheduled times

    Measured: 24 hours

  3. Comparison of relative bioavailability of Test vs. Reference after multiple dose administration after a light meal determined by use of Cmin,144-168,ss of cannabidiol

    Cmin,144-168,ss = (absolute) minimum concentrations over both dosing intervals on PK profiling day (i.e. starting with the morning dose on study day 7 to 12 h after the evening dose on study day 7), considering scheduled times

    Measured: 24 hours

  4. Comparison of relative bioavailability of Test vs. Reference after multiple dose administration after a light meal determined by use of AUC144-168,ss of 7-OH-CBD

    AUC144-168,ss = partial area under the concentration vs. time curve over both dosing intervals on PK profiling day (i.e. starting with the morning dose on study day 7 to 12 h after the evening dose on study day 7), calculated by means of the linear up/log down method (linear trapezoidal rule for increases in concentration/logarithmic trapezoidal rule for decreases in concentrations)

    Measured: 24 hours

  5. Comparison of relative bioavailability of Test vs. Reference after multiple dose administration after a light meal determined by use of Cmax,144-168,ss, of 7-OH-CBD

    Cmax,144-168,ss = observed maximum concentration over both dosing intervals on PK profiling day (i.e. starting with the morning dose on study day 7 to 12 h after the evening dose on study day 7), considering scheduled times

    Measured: 24 hours

  6. Comparison of relative bioavailability of Test vs. Reference after multiple dose administration after a light meal determined by use of Cmin,144-168,ss of 7-OH-CBD

    Cmin,144-168,ss = (absolute) minimum concentrations over both dosing intervals on PK profiling day (i.e. starting with the morning dose on study day 7 to 12 h after the evening dose on study day 7), considering scheduled times

    Measured: 24 hours

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing GLA-015 and DAC C-052 "Cannabidiol" / NRF 22.10 "Oily cannabidiol solution 100 mg/ml" in people with Comparative Bioavailability, run by SocraTec R&D GmbH at 1 site in Germany.

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 38 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 13 Jul 2021. 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 Germany. 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. 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?

Comparison of relative bioavailability of Test vs. Reference after multiple dose administration after a light meal determined by use of AUC144-168,ss of cannabidiol (time frame: 24 hours). The study lists 6 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 13 Jul 2021.
