Brief Summary:
This is a preliminary study designed to assess the safety and properties of a new oral formulation containing the two most common cannabinoids used for medicinal purposes - Tetrahydrocannabinol (THC) and Cannabidiol (CBD). The formulation is designed to disintegrate sublingually in order to enhance absorption of these ingredients by circumventing first-pass metabolism by the liver (and probably also by the intestinal mucosal cells) as well as gastric acid degradation, thus allowing a rapid onset and more intensive pharmacological effect.

Condition or disease Intervention/treatment Phase
Healthy Subjects Drug: OWCP Orally Disintegrating Tablet Drug: Sativex Phase 1

Detailed Description:

This is a single-center, open-label, single-dose, crossover, randomized, pharmacokinetic study in healthy male adults.

Sixsteen (16) subjects will participate in the study. Each subject will undergo screening procedures within 28 days prior to dosing, to assess his eligibility to participate in the study.

Eligible subjects will participate in two dosing periods. They will be randomized to one of two administration sequences - AB or BA. In each period subjects will be admitted to the clinic on the evening before dosing. On the next morning, under fasting conditions they will receive one of the following administrations, according to a randomization list:

  • Administration A: A single tablet of Medical Grade Cannabis - Orally Disintegrating Tablet (MGC-ODT) containing 5mg THC and 5 mg CBD (Test Formulation)
  • Administration B: Sativex® spray X 2 actuations (1 under the tongue and 1 inside the cheek administered within 2 min) - Reference Product [Each 100 μL spray contains 2.7 mg THC and 2.5 mg CBD, total per administration: 5.4 mg THC and 5.0 mg CBD] A taste assessment questionnaire will be filled in by the subjects 2 minutes after drug administration (immediately following water administration).

Dosing will be followed by Pharmacokinetic (PK ) blood sampling for 24 hours and Adverse Events (AE) monitoring for the next 24 hours, at time points specified below.

A washout period of at least 2 weeks is required between the dosings.

An End-of Study (EOS)/Safety Follow-up visit will take place 7-10 days after the last dose of study treatment.

Primary Outcome Measures :
  1. Pharmacokinetic parameter- Tmax determined from plasma concentrations of THC, 11-hydroxy-THC and CBD. [ Time Frame: 24 hours post dosing ]
    he amount of time requires for THC, 11-hydroxy-THC and CBD to reach to maximum concentration in serum

  2. Pharmacokinetic parameter -Cmax determined from plasma concentrations of THC, 11-hydroxy-THC and CBD. [ Time Frame: 24 hours post dosing ]
    Mean highest observed plasma concentration of THC, 11-hydroxy-THC and CBD after dosing.

  3. Pharmacokinetic parameter- AUC0-t (area under the plasma concentration-time curve) determined from plasma concentrations of THC, 11-hydroxy-THC and CBD. [ Time Frame: 24 hours post dosing ]
  4. Pharmacokinetic parameter- T½ determined from plasma concentrations of THC, 11-hydroxy-THC and CBD. [ Time Frame: 24 hours post dosing ]
    The time required for the concentration of THC, 11-hydroxy-THC and CBD to reach half of its original value

  5. Pharmacokinetic parameter- kel determined from plasma concentrations of THC, 11-hydroxy-THC and CBD. [ Time Frame: 24 hours post dosing ]
    Elimination rate constant K - The rate at which THC, 11-hydroxy-THC and CBD are removed from the body determined by their plasma concentration.

  6. Incidence of Treatment-Emergent Adverse Events [Safety and Tolerabilityof MGC-ODTand Sativex® ] [ Time Frame: 2 weeks post dosing ]
