Resveratrol is a dietary supplement that likely activates SIRT1 cellular pathways and may alter the gut microbiome. These are interesting mechanisms that may potentially alter the progression of ALS and do confer benefit in animal models of one type of familial ALS; however, to-date, there have been no trials of resveratrol in PALS. Some trials in other populations show frequent gastrointestinal adverse events, including weight loss, and one trial showed a high risk of serious renal toxicity. Given the unknown benefit of resveratrol in PALS and the possible risks, we cannot recommend resveratrol as an ALS treatment at this time. We hope to see well-designed clinical trials of resveratrol and other SIRT1 modulators in the near future.

Mechanistic plausibility

Grade A: Shown in a peer-reviewed publication to act on a relevant mechanism in humans

Mechanistic plausibility

Grade B: Shown in a peer-reviewed publication to act on a relevant mechanism in pre-clinical model(s)

Mechanistic plausibility - C

Grade C: Theoretically and plausibly acts on an ALS-relevant mechanism in humans

Mechanistic plausibility

Grade D: Acts on a biological mechanism but it is not clear that this mechanism is relevant in ALS

Mechanistic plausibility

Grade F: Implausible; would violate known principles or laws of biology

Mechanistic plausibility

Grade U: No useful information was found for this category

Pre-clinical models (animal or cell models recognized by ALSUntangled reviewers to be relevant to ALS)

Grade A: Two or more peer-reviewed publications reporting benefits in well-designed studies.

Animal studies are assumed to be ‘well designed’ when they follow published guidelines. When they deviate from these they are considered ‘flawed’.

Pre-clinical models (animal or cell models recognized by ALSUntangled reviewers to be relevant to ALS)

Grade B: One peer-reviewed publication reporting benefits in a well-designed study.

Animal studies are assumed to be ‘well designed’ when they follow published guidelines. When they deviate from these they are considered ‘flawed’.

Pre-clinical models (animal or cell models recognized by ALSUntangled reviewers to be relevant to ALS)

Grade C: One or more peer-reviewed publication(s) reporting benefits in flawed studies.

Animal studies are assumed to be ‘well designed’ when they follow published guidelines. When they deviate from these they are considered ‘flawed’.

Pre-clinical models (animal or cell models recognized by ALSUntangled reviewers to be relevant to ALS)

Grade D: One or more non-peer reviewed studies reporting benefits (published on a website or in an abstract)

Pre-clinical models (animal or cell models recognized by ALSUntangled reviewers to be relevant to ALS)

Grade F: The only studies available show no benefit

Pre-clinical models (animal or cell models recognized by ALSUntangled reviewers to be relevant to ALS)

Grade U: No useful information was found for this category

Patient case reports

Grade A: One or more peer-reviewed publications reporting benefits with validated diagnosis and benefits

Patient case reports

Grade B: More than one unpublished report of benefit with validated diagnosis and benefits

Patient case reports

Grade C: One unpublished report of benefit with validated diagnosis and benefits

Patient case reports

Grade D: Subjective report(s) of benefit without validated diagnoses and/or benefits

Patient case reports

Grade F: The only reports available show no benefit

Patient case reports

Grade U: No useful information was found for this category

Patient trials

Two or more peer-reviewed publications describing benefits in well-designed randomized, blinded placebo-controlled phase III trials

Patient trials

Grade C: One or more peer-reviewed publications reporting benefits in a well-designed randomized, blinded, placebo-controlled phase I or II trial

Patient trials

Grade D: One or more peer-reviewed publications reporting benefits in a flawed trial.

Flawed trials means those in which there are identifiable problems with patient selection, randomization, blinding, controls or follow-up. These have ‘high or unclear risk of bias’ according to published criteria. Well-designed trials are those that have ‘low risk of bias’.

Patient trials

Grade F: The only trials available show no benefit

Patient trials

Grade U: No useful information was found for this category

Risks (harms that occurred on this treatment)

Grade A: No exposed patients appear to have experienced harms

Risks (harms that occurred on this treatment)

Grade B: More than 0% but less than 10% of exposed patients experienced harms (no hospitalizations or deaths)

Risks (harms that occurred on this treatment)

Grade B (oral): More than 0% but less than10% of exposed patients experienced harms (no hospitalizations or deaths)

Grade D (intravenous): More than 0% but less than 5% of exposed patients experienced death or hospitalizations

Risks (harms that occurred on this treatment)

Grade C: At least 10% of exposed patients experienced harms (no hospitalizations or deaths)

Risks (harms that occurred on this treatment)

Grade D: More than 0% but less than 5% of exposed patients experienced death or hospitalizations

Risks (harms that occurred on this treatment)

Grade D: More than 0% but less than 5% of exposed patients experienced death or hospitalizations

Grade F: At least 5% of exposed patients experienced death or hospitalization
