Brief summary
Patients will be treated for 2 consecutive chemo cycles with the study drug for one and placebo for the other. In addition, patients will receive an injection before the chemo, either ondansetron (if receiving placebo inhalation) or normal saline) if receiving active study drug. They will take study medication for 3 days, 4 times daily and fill out VAS scores before and after doses. Patients will be given rescue medication with each dose.
Detailed description
The study is comparing the use of inhaled delata-8-THC in the prevention of nausea and vomitting in patients being treated with moderately emetogenic chemotherapy, and the patients will continue use for 3 days afterward. Patients will be given rescue medication and will fill out VAS scales for nausea, pain, appetite and dizziness. Patients will be treated for 2 cycles, one cycle receiving active drug (one of 2 doses) and the other placebo. Patients receiving placebo will receive ondansetron injection before chemo and patients receiving active drug will receive a normal saline injection. Patients will take the drug 4 times daily for 3 days. The patients will return to clinic for a visit after 24-48 hours and 4 days. Patients will bring a urine sample to measure metabolite. Patients will be given a diary to monitor dosing and side effects as well as concomitant medication. The study will be conducted in 2 - 3 centers. There will be 108 patients enrolled with 27 in each of 4 groups: Group 1 cycle 1 - Placebo cycle 2 - 300 mcg of delta-8-THC per dose Group 2 cycle 1 - Placebo cycle 2 - 600 mcg of delta-8-THC per dose Group 3 cycle 1 - 300 mcg of delta-8-THC per doseGroup cycle 2 - Placebo Group 4 cycle 1 - 600 mcg of delta-8-THC per dose cycle 2 - placebo
Interventions
DRUGinhaled delta-8-THC 300mcg or 600mcg per dose
drugs to be used to prevent/treat nausea and/or vomiting due to cancer chemotherapy drug Patients will receive chemotherapy on day 0 and receive study medication, return on day 1or 2 and again on day 4 to return medication. There will be at least 10 days between the last dose of study medication from the first cycle and the first dose for the 2nd cycle.. Patients will receive for each chemotherapy cycle either IV Ondansetron and Placebo inhalation, or IV Placebo and delta-8-THC inhalation. The patients will be randomized to receive one of 2 doses of the THC, either 300mcg or THC or 600mcg of THC

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| VAS scale for nausea | Up to 4 days after the patient receives chemotherapy. Measurements taken just before and 2 hours after inhalation morning and evening doses. | subjective measurement of feeling of nausea. Patients to indicate on a horizontal line, how much nausea the patient feels, lower score = less nausea, higher score is more severe. Measurement is made on the line from none to severe for score. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| No. of emesis | up to the 4 days after patient receives chemotherapy | number of times patient vomits recorded daily after receiving cancer chemotherapy |
| VAS scale for delayed nausea | Up to the 4 days after patient receives chemotherapy. Measurements taken just before and 2 hours after taking inhalation morning and evening doses. Delayed nausea is nausea that occurs 24 hours or more after receiving cancer chemotherapy. | Subjective measurement of feeling of nausea. Patients to indicate on a horizontal line, lower score = less nausea, higher score is more severe. Measurement is made on the line from none to severe for score. |
| VAS scale for pain | Up to the 4 days after the patient takes the study medication after receiving chemotherapy. Measurements taken just before and 2 hours after inhalation morning and evening doses | subjective measurement of feeling of pain at the moment Patients to indicate on a horizontal line, lower score = less pain, higher score is more severe pain. Measurement is made on the line from none to severe for score. |
| VAS scale for appetite stimulation | Up to 4 days after patient receives chemotherapy. Measurements are taken just before and 2 hours after taking inhalation morning and evening doses | Patients to indicate on a horizontal line, lower score = less appetite, higher score is more appetite. Measurement is made on the line from not at all to very hungry for score. |
| VAS scale for dizziness | before and 2 hours after taking inhalation, morning and evening doses. | subjective measurement of feeling dizzy Patients to indicate on a horizontal line, lower score = less nausea, higher score is more severe. Measurement is made on the line from none to severe for score. |
