Abstract An orally administered, fixed‐dose coformulation of sodium phenylbutyrate‐taurursodiol (PB‐TURSO) significantly slowed functional decline in a randomized, placebo‐controlled, phase 2 trial ALS (CENTAUR). Herein we report results long‐term survival analysis participants CENTAUR. In CENTAUR, adults with were randomized 2:1 to PB‐TURSO or placebo. Participants completing the 6‐month (24‐week) eligible receive open‐label extension. all‐cause mortality (35‐month maximum follow‐up...

To test the safety of spinal cord transplantation human stem cells in patients with amyotrophic lateral sclerosis (ALS) escalating doses and expansion trial to multiple clinical centers.This open-label included 15 participants at 3 academic centers divided into 5 treatment groups receiving increasing by numbers cells/injection injections. All received bilateral injections cervical (C3-C5). The final group both lumbar (L2-L4) through 2 separate surgical procedures. Participants were assessed...

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease of the motor nervous system. Clinical studies have demonstrated cortical and spinal neuron hyperexcitability using transcranial magnetic stimulation threshold tracking nerve conduction studies, respectively, although metrics excitability not been used as pharmacodynamic biomarkers in multi-site clinical trials.To ascertain whether ezogabine decreases ALS.This double-blind, placebo-controlled phase 2 randomized...

An interim report of a case-control study was conducted to explore the role environmental factors in development amyotrophic lateral sclerosis (ALS). Sixty-six cases and 66 age- gender-matched controls were recruited. Detailed information regarding residence history, occupational smoking, physical activity, other obtained using questionnaires. The association ALS with potential risk factors, including activity chemical exposure, investigated conditional logistic regression models. As...

SARM1, a protein with critical NADase activity, is central executioner in conserved programme of axon degeneration. We report seven rare missense or in-frame microdeletion human SARM1 variant alleles patients amyotrophic lateral sclerosis (ALS) other motor nerve disorders that alter the auto-inhibitory ARM domain and constitutively hyperactivate activity. The constitutive activity these variants similar to lacking entire greatly exceeds wild-type even presence nicotinamide mononucleotide...

Objective Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by altered metabolome and energy homeostasis, manifesting with body mass index changes hypermetabolism—both prognostic of progression survival. The cross‐sectional ALS has been characterized, but longitudinal correlations to functional decline are lacking. Methods We longitudinally evaluated metabolomes from plasma terminal postmortem spinal cord brain motor cortex tissue. constructed 3 models. A...

To elucidate amyotrophic lateral sclerosis (ALS) biomarkers and potential mechanisms of disease, we measured immune cell populations in whole blood from a large cohort patients with ALS.Leukocytes were isolated the 44 control 90 ALS. The percentages total numbers each population analyzed using flow cytometry matched patient ALS Functional Rating Scale-Revised (ALSFRS-R) score to correlate leukocyte metrics disease progression.We show significant increase percentage neutrophils decrease CD4 T...

Objective To identify dysregulated metabolic pathways in amyotrophic lateral sclerosis (ALS) versus control participants through untargeted metabolomics. Methods Untargeted metabolomics was performed on plasma from ALS (n=125) around 6.8 months after diagnosis and healthy controls (n=71). Individual differential metabolites cases were assessed by Wilcoxon rank-sum tests, adjusted logistic regression partial least squares-discriminant analysis (PLS-DA), while group lasso explored...

Abstract Objective Intraspinal human spinal cord‐derived neural stem cell ( HSSC ) transplantation is a potential therapy for amyotrophic lateral sclerosis ALS ); however, previous trials lack controls. This post hoc analysis compared ambulatory limb‐onset participants in Phase 1 and 2 (Ph1/2) open‐label intraspinal studies up to 3 years after transplant matched Pooled Resource Open‐Access Clinical Trials PRO ‐ ACT ceftriaxone datasets provide required analyses inform future clinical trial...

To determine whether neutrophils contribute to amyotrophic lateral sclerosis (ALS) progression, we tested the association of baseline neutrophil count on ALS survival, effect was sex specific, and accumulate in spinal cord.A prospective cohort study conducted between June 22, 2011, October 30, 2019. Blood leukocytes were isolated from participants levels assessed by flow cytometry. Participant survival outcomes analyzed groups (<2 × 106, 2-4 >4 106 neutrophils/mL) with adjustments for...

Penalized regression methods are used in many biomedical applications for variable selection and simultaneous coefficient estimation. However, missing data complicates the implementation of these methods, particularly when missingness is handled using multiple imputation. Applying a algorithm on each imputed dataset will likely lead to different sets selected predictors. This paper considers general class penalized objective functions which, by construction, force same variables across...
