What is the purpose of this trial?

This trial tests a new treatment called VHB937 for individuals with early-stage ALS, a disease affecting nerve cells in the brain and spinal cord. The goal is to determine if VHB937 can slow the progression of ALS symptoms. Participants are divided into two groups: one receives VHB937, and the other receives a placebo, which mimics the real treatment. Suitable candidates have experienced ALS symptoms, such as muscle weakness, for less than two years and can still exhale at least 60% of their normal capacity. As a Phase 2 trial, this research focuses on assessing the treatment's effectiveness in an initial, smaller group.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it mentions that you should not be taking any prohibited medications. If you are on a stable dose of an approved ALS treatment, you may continue with it.

Is there any evidence suggesting that VHB937 is likely to be safe for humans?

Research has shown that VHB937 has undergone previous testing to assess its safety. An earlier study found that participants generally tolerated VHB937 well, with no major safety concerns. The study examined how the body processed the drug, and results indicated effective handling.

VHB937 is now in a Phase 2 trial, suggesting that initial safety tests yielded positive results. Phase 2 trials typically proceed because the treatment has demonstrated safe use in people. Although no treatment is without risk, evidence so far suggests that VHB937 has a reasonable safety profile for further testing. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for ALS?

VHB937 is unique for treating ALS because it introduces a new approach with intravenous infusions that might offer a different mechanism than standard treatments like Riluzole and Edaravone. While traditional medications mainly work by slowing disease progression, VHB937 could potentially target underlying pathways more effectively. Researchers are excited about this treatment as it might open new avenues for managing ALS symptoms, offering hope for improved outcomes.

What evidence suggests that VHB937 might be an effective treatment for ALS?

Research shows that VHB937, which participants in this trial may receive, might help treat ALS, a disease affecting nerve cells in the brain and spinal cord. Early results suggest that VHB937, a combination of sodium phenylbutyrate and taurursodiol, could help patients with ALS live longer and maintain their abilities. The CENTAUR trial, which tested a similar combination, showed promising results for safety and effectiveness in ALS patients. While exact data for VHB937 is still being collected, positive outcomes from similar treatments offer hope for its potential benefits. ^{1 2 3 6 7}

Published Research Related to This Trial

In a study analyzing the presence of VAPB protein fragments in the cerebrospinal fluid (CSF) and peripheral blood leukocytes (PBL) of patients with sporadic ALS (SALS), it was found that a significant number of bulbar-onset SALS patients (58.7%) lacked the 14 kDa VAPB MSP fragment in their CSF, indicating a potential alteration in VAPB processing in this subgroup.

The findings suggest that the absence of the VAPB MSP fragment may be linked to the pathophysiology of bulbar-onset SALS, highlighting the importance of VAPB in motor neuron diseases and warranting further investigation into its role as a potential biomarker or therapeutic target.

In a study of 755 sporadic ALS patients and 111 familial ALS patients, researchers identified a novel mutation (p.V234I) in the VAPB gene in a familial ALS patient, suggesting a potential genetic link to the disease.

The p.V234I mutation was not found in control subjects, indicating its rarity and possible significance in ALS, further supporting the idea that multiple genetic factors may contribute to the development of the disease.

A study involving 973 Swedish, 126 Portuguese, and 19 Icelandic ALS patients found that mutations in the VAPB gene, including a novel missense mutation, were present in both ALS patients and healthy controls, suggesting these mutations are not directly linked to the disease.

The presence of VAPB mutations in healthy relatives and the lack of clinical differences in patients with these mutations indicate that they are unlikely to be pathogenic, challenging the assumption that VAPB mutations contribute to ALS.

Currently, the only FDA-approved drugs for ALS are riluzole, which modestly slows disease progression, and edaravone, which has also been shown to slow progression, offering some hope for patients.

Multidisciplinary clinics and symptomatic treatments play a crucial role in improving the quality of life for ALS patients and can help prolong their lives.

Sodium phenylbutyrate-taurursodiol (PB-TURSO) has been shown to be safe and effective for treating amyotrophic lateral sclerosis (ALS), leading to its conditional approval in Canada and full approval in the USA after the CENTAUR trial, which was a randomized, double-blind, multicenter study.

The ongoing phase 3 PHOENIX trial will further evaluate the safety and efficacy of AMX0035, a combination of PB and TURSO, but its high annual cost of $158,000 may limit access for patients with ALS.

Genetic research has identified numerous mutations linked to amyotrophic lateral sclerosis (ALS), which can help explain the disease's varied clinical presentations and improve clinical trial outcomes.

Advanced genetic sequencing techniques are paving the way for better patient stratification in clinical trials, allowing for more personalized treatment approaches and improved understanding of ALS's underlying mechanisms.

Over the past 20 years, the mean age of onset for amyotrophic lateral sclerosis (ALS) has increased, with a notable rise in cases among patients over 70 years old, indicating a demographic shift in the disease's presentation.

Patients with combined type ALS experience a significantly shorter time to primary end-point (PEP) compared to other types, suggesting that the progression rate of symptoms is a critical prognostic indicator for survival in ALS.

Overexpressing wild-type human VAPB in a mouse model of familial ALS significantly slowed neurological decline and prolonged survival of spinal motor neurons, suggesting a protective role for VAPB in motor neuron health.

The study indicates that enhancing VAPB levels may counteract some effects of ALS, as evidenced by improved muscle denervation and a slight extension in lifespan in the SOD1 G93A transgenic mice model.

A new self-reported ALS disability scale called the Rasch-Built Overall ALS Disability Scale (ROADS) was developed, consisting of 28 questions that showed improved item targeting and high test-retest reliability (0.97) compared to the existing ALS Functional Rating Scale (ALSFRS-R).

The ROADS scale demonstrated better psychometric properties and responsiveness, making it a potentially valuable tool for assessing disability in ALS patients during clinical trials and in clinical settings.

In a study of 221 ALS patients, the rate of symptom progression, particularly in respiratory and bulbar functions, was found to be a significant predictor of disease outcome, highlighting the importance of early monitoring.

Factors such as age at onset, the classification of ALS severity, and treatments like riluzole and percutaneous endoscopic gastrostomy also played crucial roles in determining patient survival, with median survival times of 915 days from symptom onset and 580 days from diagnosis.
