Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Radiation therapy to the chest is used in late stage lung cancer, and it often leads to inflammation of the esophagus. The inflammation is expected to occur in about 75% of patient, and usually begin within a week of starting radiation therapy. The esophagitis causes pain and difficulty eating. It can also result in stopping or delaying treatment.Radiation therapy to the chest is used in late stage lung cancer, and it often leads to inflammation of the esophagus. The inflammation is expected to occur in about 75% of patient, and usually begin within a week of starting radiation therapy. The esophagitis causes pain and difficulty eating. The endocannabinoid system is prominent in the gastrointestinal system, and cannabis has been shown to greatly inhibit inflammation. The compound (-)-trans-Δ9-tetrahydrocannabinol (Δ-9-THC) has effects that reduce inflammation and pain. Cannabidiol is a component of cannabis that does not produce subjective or intoxicating effects, but also has prominent anti-inflammatory properties.

The goal of this study is to perform a double-blind, placebo-controlled study to investigate the efficacy of cannabis, compared to placebo, in participants undergoing RT (Radiation Therapy) for lung cancer. Cannabis that has a high concentration of cannabidiol will be used , which is a cannabinoid that does not change perception or produce intoxication, and low in Δ-9-THC. In this way, the hope is to maximize the benefit of cannabis, while lowering the possible side effects of cannabis in medically ill participants.

Detailed Description

Study Outline

Patients will be referred to the study from their physician, who will have the patients medically cleared for participation.

The patients will then undergo additional screening for the study. A study physician will review all study procedures with potential participants, including the potential side effects. Patients will be shown the facilities and informed of being monitored at all times.

Patients will be randomized using a randomization and assigned to one of two groups: cannabis (15.76% CBD; 3.11% Δ-9 -THC) vs "placebo" cannabis (0.0% CBD/ 0.01% Δ-9-THC).

Participants will visit the Marijuana Research Laboratory, 3-5 days a week over 6 weeks to be administered 1-2 cannabis cigarettes over the course of a 2-3 hour session. Two cannabis conditions will be tested: Placebo (0.01% THC; 0.00% CBD) and CBD:THC (15.76% CBD; 3.11% THC) provided by the National Institute on Drug Abuse.

Participants will undergo baseline measurements of mood, and physical symptoms and will then be given 2 NIDA (National Institute on Drug Abuse) cannabis cigarettes, which can be consumed as smoking or with a vaporizer in a ventilated room. After the 90 minutes of cannabis availability end, participants will be asked to remain in the laboratory for an additional 45 minutes to allow the effects of the cannabis to wear off.

Participants will undergo baseline measurements of mood, and physical symptoms and will then be given the equivalent of 2 NIDA cannabis cigarettes. Cardiovascular and subjective effects measures of mood, abuse liability and drug tolerability will be collected at baseline, at the end of the 90 minutes of cannabis availability and at the end of the session. Detailed measures of food intake (caloric content, macronutrient intake) will be recorded beginning immediately after cannabis administration and for the duration of the session. In addition to visual analog scales, participants will be asked to complete measures of mood and cannabis effects at screening, before, during and after the session. Participants will be assessed at the end of the session by an experienced clinician.

Opioid use: Participants will be asked to provide the number of opioid medications taken as follows: 1) at baseline (in the week prior to starting sessions); and 2) at each session, participants will be asked about opioid use since the previous session. The amount of opioids used will be converted to oral morphine equivalents and tallied for each day.

Food intake: Participants will be asked to complete a daily food diary for the duration of the study. Detailed measures of food intake (caloric content, macronutrient intake) will also be recorded during the cannabis sessions. Participants will also be weighed weekly.

PET (Positron Emission Tomography) scans: As part of their clinical care, patients receive a PET/CT scan using the radiotracer \[18F\]FDG with a low dose CT for attenuation correction and anatomic localization. This data will be requested from the PET center, with the participants consent, in order to assess the extent of esophagitis in the two groups.
