Brief Summary
Many people receiving chemotherapy experience nausea despite standard anti-nausea medications. Medical cannabis is commonly used to help manage nausea, but there is limited scientific evidence about its effectiveness when used alongside modern chemotherapy treatments. This study will evaluate whether medical cannabis can reduce nausea in adults receiving moderately or highly nausea-causing chemotherapy. Participants will be randomly assigned to start medical cannabis either immediately or after one chemotherapy cycle, allowing comparison of symptoms with and without cannabis use. All participants will continue their usual anti-nausea medications. The study will also examine effects on vomiting, appetite, pain, fatigue, sleep, mood, quality of life, and inflammation. Results from this pilot study will help determine the safety, feasibility, and potential benefits of medical cannabis for chemotherapy-related nausea and guide future larger clinical trials.

Outcome Measures
Primary Outcomes (2)
Average and Maximum Nausea Severity as Measured by the Nausea and Vomiting Diary
Average nausea severity will be measured using a participant completed nausea and vomiting diary. Nausea severity is rated on an 11 point numeric scale anchored by "Not at all nauseated" (0) and "Extremely nauseated" (10). Average nausea is calculated as the mean of up to 15 assessment points, including afternoon, evening, and night on Day 1 and morning, afternoon, evening, and night on Days 2 through 4. Higher scores indicate greater nausea severity. Scores will be set to missing if 11 or more of the 15 assessments are missing. Maximum nausea severity will be measured using a participant-completed nausea and vomiting diary. Nausea severity is rated on an 11-point numeric scale anchored by "Not at all nauseated" (0) and "Extremely nauseated" (10). Maximum nausea is defined as the highest nausea rating reported across the same 15 assessment points.
Days 1-4 following chemotherapy administration during up to 3 on-study chemotherapy cycles (Day 1 defined as the day of chemotherapy administration; each chemotherapy cycle is 14-28 days, depending on regimen)
Number of Emesis Episodes Recorded in the Nausea and Vomiting Diary
Emesis episodes will be recorded daily by participants using the nausea and vomiting diary. The outcome is the total number of vomiting episodes recorded during the assessment period.
Days 1-4 following chemotherapy administration during up to 3 on-study chemotherapy cycles (Day 1 defined as the day of chemotherapy administration; each chemotherapy cycle is 14-28 days, depending on regimen)
Secondary Outcomes (19)
Complete Protection From Chemotherapy Induced Nausea and Vomiting
Days 1-4 following chemotherapy administration during up to 3 on-study chemotherapy cycles (Day 1 defined as the day of chemotherapy administration; each chemotherapy cycle is 14-28 days, depending on regimen)
Complete Control of Chemotherapy Induced Nausea and Vomiting
Days 1-4 following chemotherapy administration during up to 3 on-study chemotherapy cycles (Day 1 defined as the day of chemotherapy administration; each chemotherapy cycle is 14-28 days, depending on regimen)
Complete Response to Chemotherapy Induced Nausea and Vomiting
Days 1-4 following chemotherapy administration during up to 3 on-study chemotherapy cycles (Day 1 defined as the day of chemotherapy administration; each chemotherapy cycle is 14-28 days, depending on regimen)
Change in Appetite as Measured by the University of Rochester Cancer Center (URCC) Symptom Inventory
Baseline (within 7 days before chemotherapy) and Day 4 following chemotherapy during Cycles 1 and 3; post-cycle questionnaires completed on Day 4 or within 48 hours (Day 1 defined as the day of chemotherapy administration; cycles are 14-28 days).
Change in Appetite Related Quality of Life as Measured by the Functional Assessment of Anorexia Cachexia Therapy Questionnaire
Baseline (within 7 days before chemotherapy) and Day 4 following chemotherapy during Cycles 1 and 3; post-cycle questionnaires completed on Day 4 or within 48 hours (Day 1 defined as the day of chemotherapy administration; cycles are 14-28 days).
- +14 more secondary outcomes
Study Arms (2)
Immediate use
EXPERIMENTALParticipants randomized to the Immediate Use arm will receive New York State medical cannabis certification and initiate medical cannabis use during their first on-study chemotherapy cycle, in addition to standard guideline-recommended antiemetic therapy. Participants will use medical cannabis primarily during the four days surrounding chemotherapy administration, corresponding to the acute and delayed nausea period. Cannabis will be administered by vaporization using a standardized device, dose limits, and schedule. Participants will complete daily nausea and vomiting diaries, cannabis use logs, and symptom questionnaires, and will provide blood samples once per chemotherapy cycle. Outcomes in this arm will be compared to the delayed-use arm to evaluate the preliminary efficacy, safety, and feasibility of medical cannabis for chemotherapy-related nausea.
Delayed use
ACTIVE COMPARATORParticipants randomized to the Delayed Use arm will receive standard guideline-recommended antiemetic therapy alone during their first on-study chemotherapy cycle and will not use medical cannabis during this initial evaluation period. This cycle will serve as the comparison condition for nausea outcomes. After completion of the first cycle assessments, participants will receive New York State medical cannabis certification and will initiate medical cannabis use during the subsequent chemotherapy cycle. Cannabis will be administered by vaporization using a standardized device, dose limits, and schedule, primarily during the four days surrounding chemotherapy administration. Participants will complete daily nausea and vomiting diaries, cannabis use logs, symptom questionnaires, and provide blood samples once per chemotherapy cycle to evaluate changes after cannabis initiation.
Interventions
Medical cannabis will be used as an adjunct to standard guideline-recommended antiemetic therapy for chemotherapy-related nausea. Participants will obtain state-certified medical cannabis products through a New York State-licensed dispensary and self-administer cannabis via vaporization using a standardized device. Dose limits and timing of use will be guided by the study protocol to promote consistency while allowing individualized use. Medical cannabis will be used during the acute and delayed nausea period, defined as Days 1 through 4 following chemotherapy administration. Participants randomized to the Immediate Use arm will initiate cannabis use during their first on-study chemotherapy cycle, whereas participants randomized to the Delayed Use arm will initiate cannabis use after completion of the first cycle. Cannabis use patterns, nausea and vomiting symptoms, adverse effects, and patient-reported outcomes will be recorded using participant-completed diaries and questionnaires.
