About
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.
Full 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.
