While the finish line is not yet in sight, the pace of innovation is accelerating. Patients and families impacted by ALS can find encouragement in the tenacity of scientists and doctors working tirelessly to end this disease. ALS has proven a formidable foe, but the brightest minds in medicine are leveraging new tools in the ongoing quest for life-changing treatments. Here are some of the new treatments we have found that are being explored for ALS:

  • Gene therapies: Several gene therapies are being tested that aim to silence genes that cause ALS when mutated, like SOD1 and C9orf72. These use techniques like antisense oligonucleotides (ASOs) or microRNAs delivered by adeno-associated viruses (AAVs)
  • Stem cell therapies: Transplanting stem cells like mesenchymal stem cells or neural stem cells into the spinal cord aims to protect motor neurons. Some early trials have shown these to be safe, but efficacy is still unclear
  • Edaravone: This free radical scavenger was approved in Japan and the US in 2017 as a treatment that can slow ALS progression
  • Biomarkers: Biomarkers like neurofilament levels and imaging techniques are being developed to track disease progression and serve as outcome measures for clinical trials, especially for the C9orf72 mutation
  • Multidisciplinary care: Quality measures and multidisciplinary clinics with symptomatic treatments have improved quality of life and prolonged survival
  • Other experimental treatments: like antibodies, small molecules, and neurotrophic factors are also being explored as potential ALS therapies

While there is no cure yet, the understanding of ALS genetics and mechanisms has expanded greatly, leading to an emergence of targeted gene therapies and optimized clinical trial designs that provide hope for future treatments. However, challenges remain in translating discoveries into effective therapeutics. Continued research into the complex pathogenesis of ALS will be key.


Stem Cell Treatment for ALS

Mesenchymal stem cell (MSC) therapy has shown potential in treating amyotrophic lateral sclerosis (ALS) through various mechanisms, including reduction of inflammation, immunomodulation, and differentiation.

MSCs are multipotent cells that can differentiate into various cell types and have immunomodulatory and paracrine potential, releasing cytokines and factors that can inhibit the proliferation of T cells, B cells, and natural killer cells, and modify dendritic cell activity.

In ALS, MSCs have been shown to regulate innate and adaptive immune cells, release soluble factors such as TGF-β, and elevate regulatory T cells (Tregs) and T helper-2 cells (Th2 cells), which play important roles in the neuroprotective effect on motor neuronal cell death mechanisms.

A new study demonstrated that a single cycle of repeated intrathecal injections of bone marrow-derived MSCs (BM-MSCs) provided clinical benefits lasting at least six months in ALS patients, with safety. BM-MSCs have been observed to have more positive effects than Granulocyte colony-stimulating factor (G-CSF) treatments in some studies.

In summary, MSC therapy has shown potential in treating ALS through reduction of inflammation, immunomodulation, and differentiation. However, more research and clinical trials are needed to confirm the long-term efficacy and safety of this treatment approach.

Mesenchymal stem cell (MSC) therapy shows promise for treating amyotrophic lateral sclerosis (ALS) through several potential mechanisms:

  • Immunomodulation: MSCs have immunomodulatory properties that can help reduce damaging neuroinflammation in ALS. They secrete anti-inflammatory cytokines and can suppress pro-inflammatory immune cells. This may help slow neurodegeneration.
  • Neuroprotection: MSCs secrete neurotrophic factors like VEGF, GDNF, and BDNF that can protect motor neurons and support their survival. This may help slow the loss of motor neurons in ALS.
  • Cell replacement: MSCs have the ability to differentiate into various cell types including neuron-like cells. There is some evidence they may be able to replace lost motor neurons, but more research is needed in this area.
  • Reduction of oxidative stress: MSCs can reduce oxidative stress which contributes to motor neuron damage in ALS. They upregulate antioxidant enzymes like superoxide dismutase.
  • Mitochondrial support: MSCs provide support to damaged mitochondria in motor neurons, helping preserve their function. Dysfunctional mitochondria play a role in ALS pathogenesis.

While early clinical trials have shown MSC therapy to be safe, larger randomized controlled trials are still needed to definitively demonstrate efficacy in humans. Route of administration and dosage also need to be optimized. Overall, MSCs remain a promising avenue for developing an effective cell therapy for ALS.

ALS Reversal

While there have been some instances and studies suggesting the possibility of ALS reversal, these are rare and not yet fully understood. More research is needed to understand these phenomena and their potential implications for ALS treatment.

  • Instances of Possible Reversal: There have been rare instances suggesting potential ALS reversal. A notable case is that of baseball player Lou Gehrig, who experienced a temporary reversal of ALS symptoms during a three-week period in 1938. This period of regained strength, not closely examined until recently, implies that temporary ALS reversal might be possible, offering insights for researchers and those affected by the disease.
  • Scientific Research on VEGF: Studies have investigated the role of Vascular Endothelial Growth Factor (VEGF) and VEGFR2 Receptor in reversing ALS-CSF induced degeneration in the NSC-34 Motor Neuron Cell Line. Findings show that VEGF supplementation leads to the revival of cellular structures, increased calbindin expression, and enhanced cell survival, indicating VEGF's therapeutic potential in sporadic ALS.
  • Study of ALS 'Reversals': Research involving patients diagnosed with ALS who showed substantial and sustained improvement highlights the phenomenon of "ALS Reversals." These patients underwent extensive environmental exposure assessments, revealing a wide range of exposures but with significant heterogeneity. The study suggests the need for further research to identify specific differences in these "Reversal" cases.

Current Treatments for ALS

While a cure for ALS remains elusive, there are various treatment strategies available to manage the symptoms and improve the quality of life for individuals living with the disease.

Medications used in ALS management

There are currently two FDA-approved medications for the treatment of ALS: riluzole and edaravone. Riluzole works by reducing the release of glutamate, a neurotransmitter that may contribute to motor neuron damage. Edaravone, on the other hand, acts as a free radical scavenger, reducing oxidative stress and potentially slowing the progression of ALS.

In addition to these FDA-approved medications, several other drugs may be used off-label to manage specific symptoms associated with ALS. These include medications for muscle cramps, spasticity, excessive saliva production, and emotional lability. However, it is essential to note that these medications only provide symptomatic relief and do not halt or reverse the progression of the disease.

Physical and Occupational Therapy for ALS

Physical and occupational therapy play a crucial role in managing the physical limitations associated with ALS. Physical therapy aims to maintain muscle strength, prevent contractures, and improve mobility. Occupational therapy focuses on adapting activities of daily living, such as dressing, grooming, and eating, to maximize independence and functionality.

These therapies involve a combination of exercises, stretches, and assistive devices tailored to the individual's needs. They can help individuals with ALS maintain a higher level of functioning for an extended period, significantly improving their quality of life.

Speech and Nutritional support

Speech and swallowing difficulties are common in ALS, often leading to challenges in communication and maintaining adequate nutrition. Speech therapy, also known as speech-language pathology, can provide techniques and strategies to improve speech intelligibility and address swallowing difficulties.

Nutritional support is another crucial aspect of ALS management. As the disease progresses, individuals may experience difficulty swallowing, leading to weight loss and malnutrition. Nutritional supplementation and the use of feeding tubes may be necessary to ensure adequate caloric intake and prevent complications associated with malnutrition.

Brief on genetic therapies

Genetic therapies in ALS involve the delivery of therapeutic genes or gene-editing tools to correct genetic mutations that cause ALS. There are several approaches within the realm of genetic therapies, including gene replacement therapy, gene silencing therapy, and gene editing using CRISPR-Cas9 technology.

Gene replacement therapy involves delivering healthy copies of genes into motor neurons, compensating for the mutations in ALS-associated genes. Gene silencing therapy, on the other hand, aims to reduce the expression of toxic ALS-causing proteins using small interfering RNAs (siRNAs) or antisense oligonucleotides (ASOs). Finally, gene editing using CRISPR-Cas9 allows researchers to precisely edit the DNA sequence, offering the potential to correct genetic mutations and restore normal gene function.

Relevance of genetic therapies in ALS research

Genetic therapies have significant relevance in ALS research due to the high proportion of familial ALS cases associated with specific genetic mutations. By directly targeting these genetic mutations and their downstream effects, genetic therapies have the potential to halt or slow down disease progression in individuals with familial ALS.

However, it is important to note that genetic therapies may not be effective for all ALS cases, particularly sporadic ALS cases with no identifiable genetic mutations. The complexity and heterogeneity of ALS necessitate a personalized approach, tailoring treatment strategies to the specific genetic and molecular profiles of each individual.

Potential breakthroughs in ALS using genetic therapies

The potential breakthroughs in ALS using genetic therapies are promising. Recent clinical trials have demonstrated the safety and efficacy of antisense oligonucleotides in reducing the expression of toxic ALS-causing proteins. For example, the approval of nusinersen, an ASO therapy for spinal muscular atrophy, has shown the potential of gene silencing therapies in neurodegenerative diseases.

Furthermore, advancements in gene editing technologies, such as CRISPR-Cas9, offer the possibility of precisely correcting genetic mutations associated with ALS. While gene editing is still in its early stages, ongoing research is exploring its potential in ALS and other genetic disorders.
