Trial Summary

What is the purpose of this trial?

Neuropathic pain is a common complication following spinal cord injury (SCI) that significantly decreases quality of life. Treatment options are limited, and current treatments can have significant side effects. Those with SCI have identified a need for additional treatment options, particularly those that are not medications. Nabilone and an anti-inflammatory diet are two treatments that may provide pain relief while being better tolerated. This study will evaluate the benefits of these treatments for neuropathic pain after SCI. Study participants will receive either an anti-inflammatory diet or a placebo diet, and nabilone or a placebo for 4 weeks. It is expected that an anti-inflammatory diet and nabilone will significantly decrease pain intensity and improve function. The combination of both treatments together is expected to have a greater effect than each alone.

Do I have to stop taking my current medications for the trial?

You need to stop taking any cannabinoids or cannabinoid medications at least 1 month before the study. Other pain medications should be stable for at least 1 month before joining the study.

What data supports the idea that Cannabinoids + Anti-inflammatory Diet for Neuropathic Pain is an effective treatment?

The available research shows that dietary bioactive compounds, which are part of an anti-inflammatory diet, can reduce inflammation and pain in neuropathic pain. Animal studies suggest these compounds help reduce pain by affecting certain pathways in the body. Additionally, medical cannabis has been shown to alleviate neuropathic pain and improve physical conditions in specific cases, such as diabetic neuropathic cachexia. While human studies are limited, these findings suggest that combining cannabinoids with an anti-inflammatory diet could be effective for managing neuropathic pain.12345

What safety data exists for cannabinoids and anti-inflammatory diets in treating neuropathic pain?

Cannabinoids, including THC/CBD combinations and nabilone, have been evaluated for safety in treating neuropathic pain. They generally have a favorable safety profile compared to other medications, with common side effects like euphoria, drowsiness, and dizziness, and a low likelihood of severe adverse reactions or abuse. The Mediterranean diet, often considered an anti-inflammatory diet, is generally safe and associated with various health benefits, though specific safety data in the context of neuropathic pain is limited.678910

Is the anti-inflammatory diet and Nabilone drug a promising treatment for neuropathic pain?

Yes, the anti-inflammatory diet and Nabilone drug show promise for treating neuropathic pain. The diet includes bioactive compounds that reduce inflammation and pain, while Nabilone, a cannabinoid, has been effective in reducing chronic pain in clinical studies.19111213

Treatment Details

Interventions

  • Anti-inflammatory diet (Other)
  • Nabilone Capsules (Cannabinoid)
  • Placebo capsules (Other)
  • Placebo diet (Other)
Trial OverviewThe trial tests if an anti-inflammatory diet and Nabilone capsules can reduce neuropathic pain in those with spinal cord injuries better than placebo alternatives. Participants will follow the assigned diet and take either Nabilone or placebo capsules for four weeks.
Participant Groups
4Treatment groups
Active Control
Placebo Group
Group I: Anti-inflammatory diet and Nabilone capsulesActive Control2 Interventions
Capsules will be 0.5mg nabilone. Participants will take up to 8 capsules per day for a maximum dose of 4mg of nabilone per day. This meal plan will eliminate foods that have been established as pro-inflammatory (e.g. processed foods, refined sugars, refined wheat products, etc.) as well as foods that are commonly associated with even mild intolerances (e.g. cow's milk) and those that negatively impact cardiovascular health (e.g. hydrogenated oils, alcohol, coffee, refined sugars and wheat, trans fats, processed foods). In their place, the meal plan will consist of foods with established anti-inflammatory properties (e.g. (Oily fish, lean poultry, dark leafy greens, cruciferous vegetables, nuts, whole grains, most kinds of berries, etc).
Group II: Placebo diet and Nabilone capsulesActive Control2 Interventions
Capsules will be 0.5mg nabilone. Participants will take up to 8 capsules per day for a maximum dose of 4mg of nabilone per day.
Group III: Anti-inflammatory diet and placebo capsulesActive Control2 Interventions

A systematic review and meta-analysis of 12 studies involving natural compounds (nutraceuticals) showed significant reductions in neuropathic pain symptoms, including thermal hyperalgesia and mechanical allodynia, in animal models.
The findings suggest that nutraceuticals could be an effective option for managing persistent neuropathic pain, highlighting their potential clinical relevance in pain management strategies.

While cannabinoids have comparable side effects to existing pain medications, their psychoactive effects limit dosage, highlighting the need for new formulations that minimize these side effects for better pain management.
