A Phase 1, Randomised, Double-blind, Placebo-controlled, Single Ascending Dose Study in Healthy Volunteers to Evaluate the Safety, Tolerability and Pharmacokinetics of Intravenously Administered AVLX-144

This is a randomised, double-blind, placebo-controlled, single ascending dose study in healthy volunteer subjects. Each dose level will be investigated with eight 20-50-year-old male subjects (6 on active drug and 2 on placebo). Additionally, eight healthy elderly subjects (65-80 years of age, males and females), 6 on active drug and 2 on placebo, will be included in the study at one dose level, once the safety and tolerability of AVLX-144 has been documented in younger subjects.

The postsynaptic density (PSD) comprises numerous scaffolding proteins, receptors, and signaling molecules that coordinate synaptic transmission in the brain. Postsynaptic density protein 95 (PSD-95) is a master scaffold protein within the PSD and one of its most abundant proteins and therefore constitutes a very attractive biomarker of PSD function and its pathological changes. Here, we exploit a high-affinity inhibitor of PSD-95, AVLX-144, as a template for developing probes for molecular imaging of the PSD. AVLX-144-based probes were labeled with the radioisotopes fluorine-18 and tritium, as well as a fluorescent tag. Tracer binding showed saturable, displaceable, and uneven distribution in rat brain slices, proving effective in quantitative autoradiography and cell imaging studies. Notably, we observed diminished tracer binding in human post-mortem Parkinson's disease (PD) brain slices, suggesting postsynaptic impairment in PD. We thus offer a suite of translational probes for visualizing and understanding PSD-related pathologies.

Development of Peptide-Based PDZ Domain Inhibitors

Article

Author: Strømgaard, Kristian ; Balboa, Javier R ; Essig, Dominik J

Over the past decades, peptide-based drugs have gained increasing interest in a wide range of treatment applications, primarily because of high potency and selectivity, as well as good efficacy, tolerability, and safety often achieved with peptides. Attempts to target postsynaptic density protein of 95 (PSD-95) PSD-95/Discs large/Zonula occludens-1 (PDZ) domains, which mediate the formation of a ternary complex with the N-methyl-D-aspartate (NMDA) receptor and neuronal nitric oxide synthase (nNOS) responsible for excitotoxicity in ischemic stroke, by high-affinity small molecules have failed in the past. In this chapter, we focus on the discovery of peptide-based drugs targeting PSD-95, using AVLX-144 as an example, from the synthesis, over binding assays to its target, to further in vitro experiments based on the development of AVLX-144, a potential stroke treatment, which is planned to enter clinical trials in 2020.

PSD-95: An Effective Target for Stroke Therapy Using Neuroprotective Peptides

Author: Díaz-Guerra, Margarita ; Ugalde-Triviño, Lola

Therapies for stroke have remained elusive in the past despite the great relevance of this pathology. However, recent results have provided strong evidence that postsynaptic density protein-95 (PSD-95) can be exploited as an efficient target for stroke neuroprotection by strategies able to counteract excitotoxicity, a major mechanism of neuronal death after ischemic stroke. This scaffold protein is key to the maintenance of a complex framework of protein interactions established at the postsynaptic density (PSD) of excitatory neurons, relevant to neuronal function and survival. Using cell penetrating peptides (CPPs) as therapeutic tools, two different approaches have been devised and advanced to different levels of clinical development. First, nerinetide (Phase 3) and AVLX-144 (Phase 1) were designed to interfere with the coupling of the ternary complex formed by PSD-95 with GluN2B subunits of the N-methyl-D-aspartate type of glutamate receptors (NMDARs) and neuronal nitric oxide synthase (nNOS). These peptides reduced neurotoxicity derived from NMDAR overactivation, decreased infarct volume and improved neurobehavioral results in different models of ischemic stroke. However, an important caveat to this approach was PSD-95 processing by calpain, a pathological mechanism specifically induced by excitotoxicity that results in a profound alteration of survival signaling. Thus, a third peptide (TP95414) has been recently developed to interfere with PSD-95 cleavage and reduce neuronal death, which also improves neurological outcome in a preclinical mouse model of permanent ischemia. Here, we review recent advancements in the development and characterization of PSD-95-targeted CPPs and propose the combination of these two approaches to improve treatment of stroke and other excitotoxicity-associated disorders.
