DeCure for Neuronal ceroid lipofuscinosis 2

DeCure's autonomous Rare AI scientist is researching a drug-repurposing hypothesis for neuronal ceroid lipofuscinosis 2 — screening already-approved drugs against its 1-gene Open Targets disease module to publish open-access research. Research is fast; the path to publication is funded in milestone stages.

The disease map

Disease moduleNeuronal ceroid lipofuscinosis 2 maps to a 1-gene Open Targets module — the target space DeCure's AI scientist screens approved drugs against.
DeCure.ai methodSignature reversal (LINCS) plus network proximity (STRING) rank already-approved drugs likely to perturb this module — the same engine that produces DeCure.ai's repurposing hypotheses.
Repurposing thesisScreening approved medicines against this disease module, then publishing the evidence for the strongest candidate. Known pharmacology and human exposure data make the first question sharper — they do not establish safety or efficacy in a new indication.

Current lead

No approved-drug candidate for neuronal ceroid lipofuscinosis 2 is corroborated in the literature DeepSearch retrieved. Some conditions are managed with non-pharmacological care — a device, surgery or physical therapy — rather than a medicine; that may be the case here, or the literature we found may simply be too sparse yet to support a drug-repurposing angle.

Molecular view

tripeptidyl peptidase 1 (TPP1)TPP1 is one of the genes genetically linked to this disease in Open Targets — shown as context, not as a drug target we're pursuing: no approved-drug candidate for this disease is yet corroborated in the literature we found.

What the evidence adds up to

Neuronal ceroid lipofuscinosis 2 is one of at least fourteen genetically distinct forms of NCL, a group of inherited neurodegenerative disorders that begin mainly in childhood and are characterised by accumulation of autofluorescent lipopigments in neurons. The clinical course of NCL2 and its variability are still largely unknown, and the disease remains beyond remedy. Diagnosis is possible using enzymatic tests or direct sequencing of the corresponding genes.

Several therapeutic modalities have been proposed, including enzyme replacement therapy, gene therapy, stem cell therapy, small molecule pharmacotherapy, and diet modifications. Some of these have demonstrated measures of success in pre-clinical studies and have progressed to human clinical trials. However, the blood–brain barrier prevents access of many therapies to the central nervous system, and there is a need to markedly remove accumulated debris throughout the CNS. No concrete numbers for survival, response rates, or sample sizes from clinical trials in NCL2 are provided in these abstracts.

The development of mouse and large animal models has enabled comparative studies of the progressive effects of disease. Quantitative brain volumetric analysis has been proposed as a tool to precisely monitor disease progression, and the efficacy of experimental treatments will have to be evaluated on the basis of sufficient knowledge of the clinical course. What is still missing are completed clinical trials with quantifiable endpoints, validated biomarkers for disease progression, and strategies to overcome the blood–brain barrier for CNS delivery. Patient stratification by genetic subtype and disease stage also remains to be systematically addressed.

Progress towards understanding the neurobiology of Batten disease or neuronal ceroid lipofuscinosis

AbstractPURPOSE OF REVIEW: The identification of genes mutated in the neuronal ceroid lipofuscinoses has accelerated research into the mechanisms that underlie these fatal autosomal recessive storage disorders, which are often referred to as Batten disease. This review summarizes progress in this field since October 2001, describing advances in cell biology, the characterization of new animal models of neuronal ceroid lipofuscinosis, and the impact of novel methodology to reveal insights into its pathogenesis. RECENT FINDINGS: Gene products for six of the eight forms of neuronal ceroid lipofuscinosis have now been discovered, and concerted efforts are underway to understand the normal biology of each gene product and how this may be altered by mutation. Several lines of evidence point to functions for the CLN genes in the endosomal-lysosomal system, and suggest neuron-specific roles for these proteins. Indeed, a requirement for appropriate protein trafficking within neurons may explain the profound and selective effects of these disorders upon the central nervous system. The development of mouse and large animal models has enabled comparative studies of the progressive effects of disease, including characterization by morphological and biochemical means supplemented by metabonomic and microarray techniques. SUMMARY: Insights into disease mechanisms are building a detailed profile of the impact of neuronal ceroid lipofuscinosis upon the brain. With the eventual aim of developing successful therapeutic strategies, it will be equally important to characterize the clinical progression of the disorder, and to identify quantifiable endpoints that can ultimately be used in clinical trials.

Cathepsin D deficiency causes juvenile-onset ataxia and distinctive muscle pathology

AbstractThe neuronal ceroid lipofuscinoses (NCLs) are a heterogeneous group of neurodegenerative disorders with the most common phenotype consisting of early-onset progressive motor deterioration, cognitive decline, visual failure, epilepsy, cerebellar ataxia, and premature death.1 Acknowledgment: The authors thank the patients and families for help and support.

Neuronal Ceroid Lipofuscinoses

AbstractNeuronal ceroid lipofuscinoses (NCLs) are inherited neurodegenerative disorders beginning mainly in childhood, rarely in adults. They are characterized by the accumulation of autofluorescent lipopigments in brain, especially in neurons. Their clinical heterogeneity is now explained by the huge number of genes (from CLN1 to CLN14) involved in their pathogenesis. Their diagnosis is possible using enzymatic tests and/or direct sequencing of the corresponding genes. Different therapeutic approaches are in development for these diseases such as enzyme replacement therapy or gene transfer.

Advances in the treatment of neuronal ceroid lipofuscinosis

AbstractIntroduction: Neuronal ceroid lipofuscinoses (NCL) represent a class of neurodegenerative disorders typically characterized by cognitive and visual impairment, seizures, deterioration of motor skills and early mortality. There has been increased interest in developing therapies directed towards slowing the progression, and possibly preventing and reversing the impact of these disorders. Despite many challenges, including the presence of the blood–brain barrier which prevents access to the central nervous system (CNS) and the need to markedly remove accumulated debris throughout the CNS, many treatment modalities have been proposed, including enzyme replacement therapy, gene therapy, stem cell therapy, small molecule pharmacotherapy and diet modifications. Some therapies have demonstrated measures of success, and these have progressed to human clinical trials. Continued development of current therapies and discovery of newer approaches will be essential for success. Areas covered: The reader will be introduced to the 14 known NCLs, the current approach to therapies, the evidence for efficacy and the challenges to success both at the pre-clinical and clinical stage. This review corresponds to the literatures covering the years from 1968 to mid-2013. Expert opinion: Much progress has been made in the classification of this family of neurologic diseases, including the genetic basis and functional outcomes which have led to the evaluation of several therapeutic interventions. These include enzyme replacement therapy, gene therapy, stem cell therapy, small molecule pharmacotherapy and diet modifications, each of which has associated pros and cons. Successful therapies in the future may necessitate the combination of two or more therapeutic modalities.

Quantitative Brain Volumetric Analysis in Neuronal Ceroid Lipofuscinoses: A tool to precisely monitor disease progression

AbstractAims: Neuronal ceroid lipofuscinoses (NCLs) are still beyond remedy. The clinical course and its variability in the different NCL forms is widely unknown. The efficacy of experimental treatments presently being developed (gene therapy, enzyme replacement, stem cell transplantation) will have to be evaluated on the basis of sufficient knowledge of the clinical course.
