Commenting, Steve Damment, EVP R&D of Midatech, said: "These presentations provide further information on the encouraging Phase I DIPG trial results recently announced by Midatech on 19 October 2020, and preclinical efficacy data supporting the potential utility of MTX110 for the significantly larger adult glioblastoma indication."

About MTX110

MTX110 is a water-soluble form of 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 tumour. 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 treatment of brain cancers owing to poor blood-brain barrier penetration and inadequate brain drug concentrations. Based on favourable translational science data, MTX110 is being evaluated clinically as a treatment for DIPG (NCT03566199, NCT04264143) and recurrent medulloblastoma (NCT04315064), and preclinically for treatment of glioblastoma (SNO 2020 Abstract TMOD-27). MTX110 is delivered directly into and around the patient's tumour via a catheter system (e.g. CED or fourth ventricle infusions) to bypass the blood-brain barrier. This technique exposes the tumour to very high drug concentrations while simultaneously minimising systemic drug levels and the potential for toxicity and other side effects. Panobinostat has demonstrated high potency against DIPG tumour cells in in vitro and in vivo models, and in a key study it was the most promising of 83 anticancer agents tested in 14 patient-derived DIPG cell lines (Grasso et al, 2015. Nature Medicine 21(6), 555-559).
