Evidence of redox imbalance and mitochondrial dysfunction in Niemann-Pick type C 1 patients: the in vitro effect of combined therapy with antioxidants and β‐cyclodextrin nanoparticles

This research contributes to a better understanding of the mechanism of action of #cyclodextrin in Niemann Pick C, which could lead to further applications. Carmen Vargas – Federal University of Rio Grande do Sul evaluated naked and nanoparticle CDs for restoring mitochondrial functions, as well as the beneficial combined effects of treatment with antioxidant N-Acetylcysteine and Coenzyme Q10

First Patient Enrolled in Phase 1 Study of MTX-110 (MAGIC-G1 Study) in Patients with Recurrent Glioblastoma

Even though used in many formulations with CDs, new ones entering clinical trials are not often. Midatech Pharma PLC recently announced recruiting the first patient in the Phase 1 Study of MTX-110 for recurrent #glioblastoma (NCT 05324501). Midatech has previously reported encouraging results from a Phase I study of MTX110 in diffuse intrinsic pontine glioma (NCT03566199, NCT04264143), and a Phase I study of MTX110 in medulloblastoma is being undertaken. and recurrent medulloblastoma (NCT04315064).

MTX110 is a water-soluble form of a panobinostat-free base, achieved through complexation with hydroxypropyl-β-cyclodextrin (HPBCD), that enables convection-enhanced delivery (CED) at potentially chemotherapeutic doses directly to the site of the tumor. Panobinostat is a hydroxamic acid and acts as a non-selective histone deacetylase inhibitor (pan-HDAC inhibitor). The currently available oral formulation of panobinostat lactate (Farydak®) is not suitable for the treatment of brain cancers owing to poor blood-brain barrier penetration and inadequate brain drug concentrations.

MTX110 is delivered directly into and around the patient’s tumor via a catheter system (e.g., CED or fourth ventricle infusions) to bypass the blood-brain barrier. This technique exposes the tumor to very high drug concentrations while simultaneously minimizing systemic drug levels and the potential for toxicity and other side effects.

MTX110 has been granted Orphan Drug and Fast Track designations by the FDA and Orphan Medicinal Product designation by EMA.

Beren Awarded Expedited Roadmap for Treatment of Homozygous Familial Hypercholesterolemia

Fascinating news from Beren Therapeutics:
Beren Awarded Expedited Roadmap for Treatment of Homozygous Familial Hypercholesterolemia
Beren’s novel lead asset, BRN-002, was awarded an Innovation Passport under the United Kingdom’s Innovative Licensing and Access Pathway (ILAP), for the reversal of atherosclerosis in patients with Homozygous Familial Hypercholesterolemia. The ILAP aims to accelerate the time to market for innovative medicines that address the needs of patients with life-threatening or seriously debilitating diseases.
“We are excited to begin work under ILAP and look forward to collaborating with other regulators, payors, and governments to expedite the development and identify and remove access barriers.” – commented Jason Camm, CEO. Jules Payne from HEART UK – The Cholesterol Charity added that “Significant unmet needs remain, and with this advancement, we are hopeful for a new treatment option that can truly alter the course of the disease for the children and patients living with HoFH.”
Beren Therapeutics, P.B.C. is currently in stealth.

In Utero Enzyme-Replacement Therapy for Infantile-Onset Pompe’s Disease

Amazing therapeutic success led by UCSF Pediatrics joined by Duke UniversityOttawa University, and Washington University via in-utero enzyme-replacement therapy for infantile-onset Pompe’s disease: Patients with early-onset lysosomal storage diseases are ideal candidates for prenatal therapy because organ damage starts in utero. After receiving in-utero ERT and standard postnatal therapy, the current patient had normal cardiac and age-appropriate motor function postnatally, was meeting developmental milestones, had normal biomarker levels, and was feeding and growing well at 13 months of age.

Effects of Hydroxypropyl-Beta-Cyclodextrin on Cultured Brain Endothelial Cells

Heartwarming to see such important findings published by Hungarian researchers on the effects of Hydroxypropyl-beta-cyclodextrin on Cultured Brain Endothelial Cells. Cytotoxicity, permeability, and cellular internalization of HPBCD on primary rat and immortalized human (hCMEC/D3) brain capillary endothelial cells were investigated, which can help to develop new strategies for improved HPBCD effects after systemic administration.

CLN3 is required for the clearance of glycerophosphodiesters from lysosomes

A new study shows CLN3, a lysosomal transmembrane protein, is required for the lysosomal clearance of glycerophospholipid and that glycerophosphoinositol is a disease biomarker for Batten disease. Great work to advance lysosomal storage disorder treatments from a team from Stanford UniversityThe National Institutes of HealthLeibniz Institute on Aging – Fritz Lipmann Institute (FLI)Ludwig-Maximilians-Universität MünchenWhitehead Institute for Biomedical ResearchUniversity of Virginia School of Medicine and David Sabatini!
