A Phase 2, Double-masked, Randomized, Multicenter, Parallel Group, Placebo-controlled Study to Investigate the Efficacy and Safety of GAL-101, 2%, Ophthalmic Solution in Patients with Non-foveal Geographic Atrophy Secondary to Non-neovascular Age-related Macular Degeneration: EDREAM Study

Age-related macular degeneration (AMD) affects millions of elderly patients. When advanced, there is Geographic Atrophy (GA) in the retina. This means that there is an area with a loss of light-sensitive cells, called photoreceptors. That part of the retina can no longer see. Atrophy begins as a small spot in the retina distant from the fovea which is the part of the retina responsible for sharp central vision. The GA grows, and when it reaches the fovea, vision is severely diminished, and details cannot be seen anymore. The purpose of the eDREAM study is to understand if GAL-101 can slow the growth of GA and prevent it from reaching the fovea. GAL-101 is given as eyedrops. eDREAM patients will administer study eyedrops every day. Patients will be assigned by chance (randomly) to receive either eye-drops that contain the new medication, GAL-101, or eyedrops without the active drug (Placebo). Neither patients nor doctors will know which treatment was assigned to each patient until the end of the study.

MRZ-99030 (GAL-101) is a small molecule that promotes the formation of off-pathway, non-toxic amorphous clusters of Aβ thereby reducing the amount of toxic soluble oligomeric Aβ species. MRZ-99030 clearly prevents synaptotoxic effects of Aβ_1-42 oligomers on synaptic plasticity and cognition. Long lasting in vivo effects indicate that MRZ-99030 seeds a beneficial self-replication of non-toxic Aβ aggregates - "trigger effect". To test this, we prepared a serial dilution of MRZ-99030 starting with a 20:1 stoichiometric excess to Aβ_1-42. After incubating the Aβ_1-42/MRZ-99030 mixture for 20 min, 10% was transferred to a freshly prepared Aβ_1-42 solution. This dilution step was repeated 3 times finally resulting in a 500:1 stoichiometric excess of Aβ_1-42 over MRZ-99030. This solution was tested for its ability to impair long-term potentiation (LTP) in CA1 neurons. Even following serial dilution, MRZ-99030 prevented the synaptotoxic effect of Aβ_1-42 on CA1-LTP after tetanic stimulation of the Schaffer collaterals whereas incubation with MRZ-99030 (0.1 nM) without serial dilution did not prevent the synaptic deficits caused by Aβ_1-42 (50 nM). Time course experiments revealed that this protective effect was still evident even when the serially diluted Aβ_1-42/MRZ-99030 mixture was prepared up to 1 week before the LTP experiment. MRZ-99030, when serially diluted with Aβ_1-42, was also capable of detoxifying/reversing an already established neurotoxic process. In TEM experiments, Aβ oligomers/annular protofibrils were converted to amorphous Aβ clusters following incubation with serially diluted MRZ-99030 to a final concentration of MRZ-99030 (20 nM) and Aβ_1-42 (10 μM).

β-amyloid1-42 (Aβ1-42) is a major endogenous pathogen underlying the aetiology of Alzheimer's disease (AD). Recent evidence indicates that soluble Aβ oligomers, rather than plaques, are the major cause of synaptic dysfunction and neurodegeneration. Small molecules that suppress Aβ aggregation, reduce oligomer stability or promote off-pathway non-toxic oligomerization represent a promising alternative strategy for neuroprotection in AD. MRZ-99030 was recently identified as a dipeptide that modulates Aβ1-42 aggregation by triggering a non-amyloidogenic aggregation pathway, thereby reducing the amount of intermediate toxic soluble oligomeric Aβ species. The present study evaluated the relevance of these promising results with MRZ-99030 under pathophysiological conditions i.e. against the synaptotoxic effects of Aβ oligomers on hippocampal long term potentiation (LTP) and two different memory tasks. Aβ1-42 interferes with the glutamatergic system and with neuronal Ca(2+) signalling and abolishes the induction of LTP. Here we demonstrate that MRZ-99030 (100-500 nM) at a 10:1 stoichiometric excess to Aβ clearly reversed the synaptotoxic effects of Aβ1-42 oligomers on CA1-LTP in murine hippocampal slices. Co-application of MRZ-99030 also prevented the two-fold increase in resting Ca(2+) levels in pyramidal neuron dendrites and spines triggered by Aβ1-42 oligomers. In anaesthetized rats, pre-administration of MRZ-99030 (50 mg/kg s.c.) protected against deficits in hippocampal LTP following i.c.v. injection of oligomeric Aβ1-42. Furthermore, similar treatment significantly ameliorated cognitive deficits in an object recognition task and under an alternating lever cyclic ratio schedule after the i.c.v. application of Aβ1-42 and 7PA2 conditioned medium, respectively. Altogether, these results demonstrate the potential therapeutic benefit of MRZ-99030 in AD.

MRZ-99030 – A novel modulator of Aβ aggregation: I – Mechanism of action (MoA) underlying the potential neuroprotective treatment of Alzheimer's disease, glaucoma and age-related macular degeneration (AMD)

Therapeutic approaches addressing β-amyloid1-42 (Aβ1-42) aggregation represent a promising neuroprotective strategy for the treatment of Alzheimer's disease, dry age-related macular degeneration (AMD) and glaucoma. MRZ-99030 is a dipeptide containing d-tryptophan and 2-amino-2-methylpropionic acid in clinical development for the topical treatment of glaucoma and AMD. MRZ-99030 is an Aβ aggregation modulator, previously reported to prevent the formation of soluble toxic oligomeric Aβ species. The present study confirmed that MRZ-99030 prevents the formation of oligomeric Aβ species using similar SDS-PAGE experiments. However, additional data from TR-FRET, DLS and AFM experiments revealed that MRZ-99030 does not directly prevent early protein/protein interactions between monomeric Aβ, but rather promotes the formation of large, non-amyloidogenic, amorphous Aβ aggregates and thereby reduces the amount of intermediate toxic soluble oligomeric Aβ species. The affinity of MRZ-99030 to Aβ1-42 determined by SPR was 28.4 nM but the ratio of compound to Aβ is also important: a 10-20 fold excess of MRZ-99030 over Aβ is probably required for effective modulation of protein/protein interactions. For example, in glaucoma, assuming a maximal Aβ concentration of 1-15 nM in the retina, up to 150 nM MRZ-99030 could be required at the protein target. In line with this consideration, MRZ-99030 was able to prevent Aβ-induced toxicity on PC12 cells, retinal ganglion cells and retinal pigment epithelium cells when present at a 10-20 fold stoichiometric excess over Aβ. Moreover, in vivo studies demonstrate the neuroprotective potential of MRZ-99030 after systemic and topical administration in animal models of Alzheimer's disease and glaucoma/AMD respectively.

Galimedix Therapeutics presents new scientific data showing promising neuroprotective effects of GAL-201 for the treatment of Alzheimer’s disease at AD/PD™ 2024

GAL-201 specifically targets and binds to misfolded Aβ monomers, preventing their aggregation to toxic Aβ oligomers and protofibrilsAs a consequence, consistent beneficial effects have been demonstrated on synaptic spine density and on cognitive performance after single injection of GAL-201 in transgenic models of Alzheimer’s diseaseThese results warrant initiation of an IND-enabling program as next step towards clinical development KENSINGTON, Md., March 08, 2024 (GLOBE NEWSWIRE) -- Galimedix Therapeutics, Inc. (“Galimedix”), a Phase 2 clinical-stage biotechnology company developing novel oral and topical neuroprotective therapies with the potential to revolutionize the treatment of serious eye and brain diseases, announces encouraging data with orally available small molecule GAL-201, showing its neuroprotective and symptomatic alleviation potential in models of Alzheimer’s disease (AD). These new findings strongly support previous studies where GAL-201 was characterized as a promising development candidate for the treatment of AD (Russ et. al. 2022). The data was presented this week at the International Conference on Alzheimer’s and Parkinson’s Diseases and related neurological disorders (AD/PD™ 2024: advances in science and therapy). “The small molecule GAL-201 belongs to a new pharmacological class of amyloid beta aggregation modulators that acts upstream of other known Aβ-targeting agents,” explained Hermann Russ, M.D., Ph.D., Co-founder, and Chief Scientific Officer of Galimedix. “The positive results presented at AD/PD™ 2024 demonstrate how treatment with GAL-201 has a potential neuroprotective effect and may also improve cognitive function. Furthermore, they validate that toxic Aβ oligomers and protofibrils are a major underlying cause of this devastating disease, and not the deposited forms of Aβ. We look forward to advancing this promising new drug candidate into the clinic.” Data from the poster, entitled “The amyloid beta aggregation modulator GAL-201 is under development for oral AD treatment: Cognitive improvement in a transgenic AD model”, showed a high affinity of GAL-201 to misfolded Aβ monomers, the precursors of the neurotoxic forms of Aβ oligomers and protofibrils. Binding of GAL-201 to the Aβ monomers significantly prevented Aβ-induced suppression of long-term potentiation (LTP), considered a neuronal correlate of learning and memory. These results mirrored morphological changes observed in neuronal cells (dendrites), where Aβ-induced spine loss was also prevented. Preserving dendritic spines is essential, as they are correlated with synaptic plasticity. Additionally, in behavioral experiments using AD animal models, a single injection of GAL-201 resulted in improved cognitive performance, both in duration (escape latency) and accuracy (left and right decisions) performing a task (water-cross maze) and were comparable to healthy mice. The presented results further substantiate GAL-201’s role as a promising future Aβ-targeting treatment for AD, with an advanced mechanism of action and a patient-friendly application route as an oral tablet. The next step is to move GAL-201 towards IND submission and clinical development. The poster can be accessed here: “The amyloid beta aggregation modulator GAL-201 is under development for oral AD treatment: Cognitive improvement in a transgenic AD model” About GAL-201GAL-201 is an orally administered small molecule specifically designed to target amyloid beta (Aβ) and suppress the formation of toxic forms of Aβ aggregates in the brain of people with AD.
