There is an unmet need for reliable biomarkers for amyotrophic lateral sclerosis (ALS). Recent studies have demonstrated that the levels of the microtubule-associated protein tau, are altered in plasma and cerebrospinal fluid (CSF) from people with ALS. Our previous findings demonstrated that while the ratio between tau and phosphorylated tau at T181 (pTau-T181) is decreased, increases in CSF tau correlated with faster disease progression in people with ALS.

Background And Objectives: The lack of approved therapies for N-methyl-d-aspartate receptor (NMDAR) encephalitis has contributed to substantial variability in treatment. Inebilizumab is a humanized anti-CD19 monoclonal antibody that can be administered intravenously. Inebilizumab may be an efficacious treatment for patients with NMDAR encephalitis, with the potential to achieve early robust and sustained suppression CD19 plasmablasts, some plasma cells, and NMDAR autoantibodies, with the potential to improve short-term and long-term outcomes in patients with NMDAR encephalitis.

We propose a new approach to funding disease-specific drug development via a variation of the adaptive platform trial. This trial is designed to test a portfolio of drug candidates in parallel, with the cost of the trial partially covered by investors who receive payments from a royalty fund of the candidates in exchange for investment. Under realistic assumptions for cost, revenue, probability of success, drug sales, and royalty rates, investors may expect a return of 28%, but with a 22% probability of total loss.

: To describe the development of a methodology to characterize hospitalizations and their relationship to amyotrophic lateral sclerosis (ALS) and provide results using this process in a phase 3 trial of in ALS. : ALS clinical trialists assisted in developing a classification system to determine if a hospitalization was related to ALS (HR-ALS), unrelated (HU-ALS), or if the relationship was indeterminate (HI-ALS) and this was applied by the investigators to hospitalizations in COURAGE-ALS. Time to first hospitalization and number of hospitalizations were compared between those assigned or placebo for up to 48 weeks.

Aims: RNS60 is an investigational product in clinical development for amyotrophic lateral sclerosis (ALS). RNS60 slowed disease progression in the ALS SOD1 mouse model and was safe and well tolerated both in an open-label pilot study and a randomized, placebo-controlled, multicenter phase 2 trial in people living with ALS. The objective of this ongoing expanded access protocol (EAP) was to provide RNS60 to people living with ALS who are ineligible for controlled clinical trials and to collect data on the safety and tolerability of dosing RNS60 via twice-daily nebulization rather than the previously studied daily nebulization with weekly intravenous administration.

Introduction/aims: Akt intracellular signal transduction pathway dysfunction has been reported in people with amyotrophic lateral sclerosis (ALS) providing a novel target for intervention in this devastating progressive disease. This first-in-human study evaluated the safety, tolerability, and preliminary efficacy of the Akt pathway activator, IPL344, in people with ALS.

Methods: Nine participants with ALS and a progression rate > 0.

Importance: Bioenergetic failure has been proposed as a driver of amyotrophic lateral sclerosis (ALS). CNM-Au8 is a suspension of gold nanocrystals that catalyzes the conversion of nicotinamide adenine dinucleotide hydride into NAD+, resulting in an increase of cellular adenosine triphosphate production.

Objective: To determine the effects of CNM-Au8 on ALS disease progression.

Importance: Myeloperoxidase is one of the most abundant peroxidase enzymes in activated myeloid cells. Myeloperoxidase inhibitors may have a clinical benefit in amyotrophic lateral sclerosis (ALS) by slowing neurodegeneration via reduced neuroinflammation and oxidative stress.

Objective: To determine the safety, tolerability, and efficacy of verdiperstat, a selective myeloperoxidase inhibitor, in ALS.

Importance: The etiology of amyotrophic lateral sclerosis (ALS), a fatal neurodegenerative disease, is unknown. However, neuroinflammation and complement activation may play a role in disease progression.

Background: Fragile X syndrome, with an approximate incidence rate of 1 in 4000 males to 1 in 8000 females, is the most prevalent genetic cause of heritable intellectual disability and the most common monogenic cause of autism spectrum disorder. The full mutation of the Fragile X Messenger Ribonucleoprotein-1 gene, characterized by an expansion of CGG trinucleotide repeats (>200 CGG repeats), leads to fragile X syndrome. Currently, there are no targeted treatments available for fragile X syndrome.

Amyotrophic lateral sclerosis (ALS) is a relentless, fatal neurodegenerative disease. The progressive loss of voluntary muscle function, diagnostic delays, lack of effective treatments, and challenges accessing multidisciplinary care and resources have tremendous impact on quality of life. The congressionally directed ALS committee of the National Academies of Science, Engineering, and Medicine, in their 2024 report "Living with ALS," recommends critical actions for specific United States stakeholders to make ALS a livable disease over the next decade.

Amyotrophic lateral sclerosis (ALS) is an orphan neurodegenerative disease. Immune system dysregulation plays an essential role in ALS onset and progression. Our preclinical studies have shown that the administration of exogenous allogeneic B cells improves outcomes in murine models of skin and brain injury through a process termed pligodraxis, in which B cells adopt an immunoregulatory and neuroprotective phenotype in an injured environment.

Introduction/aims: Expanded access (EA) is a Food and Drug Administration-regulated pathway to provide access to investigational products (IPs) to individuals with serious diseases who are ineligible for clinical trials. The aim of this report is to share the design and operations of a multicenter, multidrug EA program for amyotrophic lateral sclerosis (ALS) across nine US centers.

Methods: A central coordination center was established to design and conduct the program.

Article Synopsis
  • This study looked at how a treatment called debamestrocel affects special substances in the body (biomarkers) in people with ALS, a disease that affects muscles.
  • They tested 196 people, some got the treatment while others got a fake treatment (placebo) and checked their cerebrospinal fluid (CSF) for 45 different biomarkers.
  • Results showed that debamestrocel improved many of these biomarkers, which could mean it's helping to protect nerves and reduce inflammation, especially in patients with more advanced ALS.

Introduction/aims: Genetics is an important risk factor for amyotrophic lateral sclerosis (ALS), a neurodegenerative disease affecting motor neurons. Recent findings demonstrate that in addition to specific genetic mutations, structural variants caused by genetic instability can also play a causative role in ALS. Genomic instability can lead to deletions, duplications, insertions, inversions, and translocations in the genome, and these changes can sometimes lead to fusion of distinct genes into a single transcript.

Background: An oral sodium phenylbutyrate and taurursodiol combination (PB and TURSO) significantly reduced functional decline in people living with amyotrophic lateral sclerosis (ALS) in the CENTAUR trial. Biomarkers linking clinical therapeutic effect with biological changes are of high interest in ALS. We performed analyses of neuroinflammatory biomarkers associated with ALS in the literature, including YKL-40 (also known as chitinase-3-like protein 1), chitinase 1 (CHIT1) and C reactive protein (CRP), in plasma samples collected in CENTAUR.

Objective: Sodium phenylbutyrate and taurursodiol (PB and TURSO) was evaluated in amyotrophic lateral sclerosis (ALS) in the CENTAUR trial encompassing randomized placebo-controlled and open-label extension phases. On intent-to-treat (ITT) survival analysis, median overall survival (OS) was 4.8 months longer and risk of death 36% lower in those originally randomized to an initial 6-month double-blind period of PB and TURSO versus placebo.
