Design outcomes

Primary

MeasureTime frame
Main Objective: The objective of the study is to quantify the interactive effect of ?9-tetrahydrocannabinol (THC) and oxycodone on ventilatory control. ;Secondary Objective: (1) Outcome of Bowdle and Bond & Lader questionnaires; (2) Level of sedation; (3) Hemodynamics; (4) Cognition (p-deletion test); (5) Pain Pressure Threshold; (6) slope of the hypercapnic ventilatory response; (7) plasma concentrations of THC, 11-OH-THC and oxycodone; a secondary analysis will be performed on the pharmacokinetic and pharmacodynamic data (PKPD modeling).;Primary end point(s): The effect of inhaled THC on ventilation at an end-tidal PCO2 = 55 mmHg without and with concomitant intake of 20 mg oxycodone immediate release (IR) tablet in healthy volunteers 120 min after oxycodone intake. ;Timepoint(s) of evaluation of this end point: 120 minutes after intake oxycodone or placebo

Secondary

MeasureTime frame
Secondary end point(s): (1) Outcome of Bowdle and Bond & Lader questionnaires; (2) Level of sedation; (3) Hemodynamics; (4) Cognition (p-deletion test); (5) Pain Pressure Threshold; (6) slope of the hypercapnic ventilatory response; (7) plasma concentrations of THC, 11-OH-THC and oxycodone; a secondary analysis will be performed on the pharmacokinetic and pharmacodynamic data (PKPD modeling).;Timepoint(s) of evaluation of this end point: variable and across timepoints in trial
