Phase 1

Not yet recruiting

• Conditions: Nausea Post Chemotherapy; Vomiting; Cancer Pain; Cancer Related Pain; Neoplasms
• Interventions: Drug: Pharmacokinetic and pharmacodynamic profile of THC oral formulations with Dronabinol as comparator

• Registration Number: NCT05272865
• Lead Sponsor: LaSanta S A S

Brief Summary

Study based on the pharmacokinetic, pharmacodynamic, safety and stability evaluation of 3 standardized formulations of THC, to be used in healthy volunteers and post-chemotherapy patients as an adjuvant in the symptomatic treatment of the latter in discomfort associated with cancer treatment, with the aim of possible new therapeutic entities.

Detailed Description

This evaluation project of 3 oral formulations of Δ9-THC will be carried out in two phases: Phase I evaluation of bioequivalences in healthy subjects and Phase II evaluation of safety and effectiveness comparing with the reference product (Dronabinol 5mg/mL), formulations derived from cannabis for the management of nausea, vomiting post chemotherapy and exploratory in cancer pain.

Arm && Interventions

Group	Intervention	Description
Dronabinol 5mg/mL	Pharmacokinetic and pharmacodynamic profile of THC oral formulations with Dronabinol as comparator	Drug: Dronabinol (SYNDROS) Oral solution of SYNDROS (5 mg/mL)
THC F1	Pharmacokinetic and pharmacodynamic profile of THC oral formulations with Dronabinol as comparator	Drug: THC Oral solution of THC (5 mg/mL)
THC F2	Pharmacokinetic and pharmacodynamic profile of THC oral formulations with Dronabinol as comparator	Drug: THC:CBG Oral solution of THC (5 mg/mL) \& CBG (5 mg/mL)
THC F3	Pharmacokinetic and pharmacodynamic profile of THC oral formulations with Dronabinol as comparator	Drug: THC:CBC Oral solution of THC (5 mg/mL) \& CBC (5 mg/mL)

Primary Outcome Measures

Name	Time	Method
Pharmacokinetic assessment profile of THC formulations	48 hours with a replicate 7 days after the first dose in healthy subjects and the same time but with successive doses in post-chemotherapy patients	Pharmacokinetics of THC by Assessment of Area Under the Curve From Time Zero Extrapolated to Infinity (AUC(0-inf)) \[ Time Frame: 0 hours (pre-dose), as well as at 0.12, 0.25, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 12, 16, 24, 36 and 48 hours post-dose \]
Pharmacodynamic assessment profile of THC formulations: BPI	Post-chemotherapy patients for at least 20 days with a daily report	Brief pain inventory (BPI); The Brief Pain Inventory (BPI) rapidly assesses the severity of pain and its impact on functioning. The questions ask participants to rate their pain in the prior 24-hours OR prior 7-day on a 0 to 10 Numerical Rating Scale (NRS), where "0" indicates "No pain" and "10" indicates "Pain as bad as you can imagine."
Pharmacodynamic assessment profile of THC formulations: DEQ	48 hours with a replicate of 7 days after the first dose in healthy subjects and on the other hand post-chemotherapy patients for at least 20 days with a daily report	Drug Effects Questionnaire (DEQ);is used in studies of acute subjective response (SR) to a variety of substances. The DEQ consists of 11 questions: "Feel Drug", "Feel High", "Like Drug", and "Want More", "dislike the sensation", "any sensations", "feel a head rush", "like drug effect", "dislike any effects". To calculate the DEQ- 'Good Drug Effects'. Each question was measured on a scale with a minimum score of 0 and a maximum score of 100. 100 represents the highest score for that subjective state, and the higher the score, the worse the outcome
No significant nausea in terms of the proportion of subjects with no significant nausea	Post-chemotherapy patients for at least 20 days with a daily report	To investigate THC oral formulations in terms of the proportion of patients with no significant nausea (none or mild nausea) following initiation of oral formulations of THC (dronabinol) in post-chemotherapy patients

Secondary Outcome Measures

Name	Time	Method
Number of participants with treatment-related adverse events as assessed by CTCAE v4.0	14 days for healthy subjects, 20 days for post-chemotherapy patients	Evaluate the Safety and Tolerability of Oral Formulations of THC, Number of AEs during 14 days for healthy subjects and 20 days for post-chemotherapy patients vs active drug phase vs. Dronabinol active comparator
Global Quality of Life (QoL) of the European Organisation for Research and Treatment of Cancer (EORTC) quality of life questionnaire	at least 20 days for post-chemotherapy patients	EORTC quality of life questionnaire (QLQ) is an integrated system for assessing the health-related quality of life (QoL) of cancer patients participating in international clinical trials.; Self-reported symptoms related to treatment. Each item is rated on a response scale 1 = not at all to 4 = very much and refer to the time frame "during the last days" EORTC QLQ-C30
