Group	Intervention	Description
Placebo	Placebo	Placebo inhalation with a device
inhaled THC/CBD (PPP001)	PPP001	PPP001 (cannabis dosing capsule with THC/CBD) inhalation with a device

Primary Outcome Measures

Name	Time	Method
Uncontrolled cancer pain will be measured using a patient self-administered questionnaire.	change from baseline in the EORTC-QLQ-C15-PAL pain multi-item scale score at Week 4.	European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Core 15 Palliative (EORTC-QLQ-C15-PAL). items are rated on a scale of 1 (not at all) to 4 (very much). high scores on a symptom scale correlate to increased symptom burden

Secondary Outcome Measures

Name	Time	Method
The overall HRQoL (Health related Quality of Life) of patients with uncontrolled symptoms related to advanced cancer will be measured using a patient self rating questionnaire.	change from baseline in the EORTC-QLQ-C15-PAL overall QoL single-item scale score at Week 4	European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Core 15 Palliative (EORTC-QLQ-C15-PAL). single-item scale is rated from 1 (very poor) to 7 (excellent). High scores on a functional scale correspond to better functioning
The physical, emotional, and total symptom distress will be measured using a patient self administered questionnaire.	Change from Baseline in ESAS-r-CS at Weeks 1 and 4	Revised Edmonton Symptom Assessment System (ESAS-r-CS). 11 core symptoms: pain, tiredness, nausea, depression, anxious, drowsiness, appetite, feeling of well-being, shortness of breath, constipation and trouble sleeping. 11-point NRS ranging from 0 (no symptom) to 10 (worst possible).
The palliative performance scale will be scored by a healthcare profesional.	Change from Baseline in PPS at Weeks 1 and 4	palliative performance scale version 2 (PPSv2) for measuring functional status in end-of-life patients. A healthcare professional scores each dimension by assigning a value from 100% to 0% (death), with 10% denoting the lowest level of functioning
The satisfaction of family caregivers of patients with advanced cancer will be measured using a caregiver self administered questionnaire.	Change from Baseline in treatment-satisfaction questionnaire at Weeks 1 and 4	The treatment satisfaction questionnaire (change version) will be used. Scale range is a left to right 7-item scale for caregiver. each item is scored from 5 (Much more satisfied now) to 1 (Much Less satisfied now).
The distress of patients with advanced cancer will be measured using a patient self-administered questionnaire	Change from Baseline in distress thermometer at Week 4	distress thermometer adopted as a screening measure to identify and address psychological distress in individuals with cancer. Results support a cut-off score of 3 on the DT to indicate patients with clinically elevated levels of distress .
