ALS Untangled®

ALSUntangled® reviews alternative and off label treatments (AOTs), with the goal of helping people with ALS make more informed decisions about them.

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’.

Endotherapia

by

Endotherapia has a proposed mechanism that hinges on the ability of an isolated laboratory’s immunoblots to identify the cause and specific pathways that are driving ALS progression. In our opinion this ability has never been convincingly demonstrated. While there is a flawed animal study supporting the utility of Endotherapia in rats, such studies rarely translate into useful human treatments (29). The data on Endotherapia in PALS have so many problems that we believe they are uninterpretable. ALSUntangled does not recommend the use of Endotherapia for ALS at this time. A reasonable next step would be a study to validate the utility of the above-described immunoblots, ideally by a group without a potential conflict of interest.

Methylcobalamin

by

MeCbl has promising mechanisms and positive preclinical data from two different ALS models. Unfortunately, the anecdotal data we found did not identify any clear specific benefit, and the best of three clinical trials was unable to show an overall difference in ALSFRS-R progression or survival between PALS treated with MeCbl and those treated with placebo (26). A sub-group of patients with very specific pretreatment progression rates of 1–3 ALSFRS-R points over 12 weeks, and very early disease (less than 12 months from symptom onset) may have had benefit (26). This finding needs to be replicated, especially since an earlier study suggested patients with longer disease duration were more likely to benefit (20). We would like to see a full traditional sub-group analysis (28) carried out on the data from the third trial (26). This sub-group analysis could then be used to design inclusion criteria for a new phase III trial comparing MeCbl 50 mg twice a week IM to placebo. The new trial could measure serum B12 and homocysteine, and have pre-planned sub-group analyses that are both logical and practical. While we wait for this, PALS who wish to try MeCbl are reminded that the above studies used very high, injected doses, which appear to be available only by prescription. Lower over-the-counter doses administered orally have not been studied. It is well established that over-the-counter oral supplements may be of poor and inconsistent quality (32). Some over-the-counter oral vitamin B supplements contain not only B12 but also B6, which in large quantities can be harmful to the nervous system (33).

Mito Q

by

MitoQ has a promising mechanism, positive preclinical data from two different ALS models, and appears reasonably safe and inexpensive, especially at doses of 10 mg daily. Available anecdotal data are insufficient to determine how helpful this might be in PALS. A small open-label pilot trial with validated ALS diagnoses and outcomes appears warranted.

Acupuncture

by

Acupuncture is reasonably safe, and has potential mechanisms of action, pre-clinical studies and case reports suggesting that it could be a useful treatment for ALS. However, before it can be endorsed even as a candidate for a phase II trial, the studies described above need to be independently replicated using more clearly verified diagnoses and more rigorous designs, including appropriate controls and validated ALS outcome measures.

Vitamin D

by

At this time, there is evidence that PALS, like those with other chronic illnesses, are at increased risk for vitamin D deficiency. It is, therefore, reasonable to screen PALS for this. If vitamin D deficiency is found, it seems reasonable to supplement vitamin D according to established guidelines (31) in order to avoid medical complications of vitamin D deficiency. It is not yet clear, however, that vitamin D supplementation can slow disease progression, improve muscle strength, or reduce falls in PALS. We support further studies to answer these questions.

Deanna Protocol

by

Mitochondrial dysfunction, glutamate excitotoxicity, and oxidative stress have all been implicated in ALS pathogenesis, and targeting these mechanisms individually or by a cocktail such as the Deanna Protocol could play a role in future ALS therapies. However, many of the preclinical and animal studies related to these pathways have not translated into successful treatments in patients with ALS. While there are anecdotal reports of improvements in patients with ALS on the Deanna Protocol, there is no convincing objective evidence of benefit yet. Thus, at this time, ALSUntangled does not recommend the Deanna Protocol to patients with ALS.

Before it can be recommended, a reproducible version of the Deanna Protocol should be shown to influence plausible physiologic mechanisms such as central nervous system ketone bodies, as well as clinically meaningful outcome measures such as ALSFRS-R and FVC in patients with ALS.

Cannabis

by

Cannabis has biological properties including immunomodulation and effects on excitototoxicity that suggest it could be useful in ALS. Evidence from small, non-randomized, unblinded animal studies suggest that it could potentially slow ALS progression, and anecdotal reports suggest that it could ameliorate troubling ALS symptoms. Given all this, ALSUntangled supports further careful study of cannabis and cannabinoids, the active ingredients contained therein. Natural cannabis, as a single agent, provides advantages similar to a multiple drug trial given its numerous mechanisms of action. A possible next step would be a small case series of well-characterized PALS using cannabis at controlled dosages that could potentially be monitored by blood levels of cannabinoids, compared to matched controls, performed in a geographic area where it would be legal.

Bee Venom

by

In our opinion, BV has biological effects that could potentially be useful in ALS. Two ALS-animal studies in which BV was injected into an unusual anatomic location showed positive effects on motor preservation and inflammatory markers; one showed improved survival. However, there are some significant problems with these animal studies. They do not meet methodological standards for preclinical animal research (14, 15) for the following reasons: treatment allocation was not randomized, power arguments are not presented, sample sizes are too small, potential confounders such as gender and copy number variation are not adequately addressed, criteria for determining symptomatic disease onset are not defined, blinding is not described, outcome measures in control animals are not compared to those in other studies to demonstrate external validity, and replication of results is via the same, rather than an independent group of authors. Furthermore, it is not currently possible to replicate pre-symptomatic drug delivery in humans with sporadic ALS. Many other compounds given pre-symptomatically to ALS-animals have failed to yield any positive benefit in human patients (16); indeed one immune-modulator that worked in ALS-animals actually appeared to accelerate disease progression in patients with sporadic ALS (17). It may not be possible to replicate the dosage of BV that was used in future human studies; by one estimate, for a 70g human this would require 70,000 bee stings twice a week (18). Finally and most importantly, we found very little data of any kind on BV exposure in humans with ALS; the two anecdotal reports describe unverified, non-overlapping benefits. Given all this, and the costs and risks of BV (which include death), ALSUntangled does not support the use of BV by patients with ALS outside of a study at this time. Replication of the animal studies via an independent group following published methodological guidelines and using a dosing regimen that could eventually be translated to human studies would be a reasonable next step.
