Life Molecular Imaging announces an ongoing collaboration with UCB for PI-2620, a novel tau imaging agent, for improved diagnosis of Progressive Supranuclear Palsy
BERLIN, March 3, 2021 /PRNewswire-PRWeb/ -- Life Molecular Imaging today announces an ongoing collaboration with UCB Biopharma to investigate the utility of the tau-positron emission tomography (PET) tracer PI-2620 in patients with progressive supranuclear palsy (PSP). This collaboration has been in place for the past few years.
PI-2620 is shown to be a promising biomarker for the improved detection and characterization of this currently untreatable, fatal disease. Recently published clinical data indicate that PI-2620 could facilitate an earlier and more reliable diagnosis of PSP , where previous tau tracers and other biomarkers failed.
PSP is a rare disease that affects approximately 6 out of every 100,000 individuals worldwide. Patients can be challenging to diagnose especially at early disease stages because they show symptoms, such as movement difficulties, stiffness, clumsiness, cognitive impairment, and frequent falls that are also present in other neurodegenerative diseases, like Parkinson's disease. Misdiagnosis of PSP hampers drug development due to heterogeneous study populations, mixing patients with tau-related pathologies and patients suffering from other proteinopathies.
PI-2620 was discovered and developed in a research collaboration between Life Molecular Imaging and AC Immune, a Swiss-based clinical stage biopharmaceutical company . Life Molecular Imaging has the exclusive, worldwide license for research, clinical development and commercialization of tau PET tracers generated within the discovery program. PI-2620 is currently under investigation as a targeted radiopharmaceutical for the detection of tau depositions in Alzheimer's disease and other primary tauopathies such as PSP.
Describing the partnership, Mark Hope, SVP and Head of the Neurodegeneration Mission, UCB, explained: "There is a need to confirm pathophysiology in PSP patients and to be able to offer the potential to participate in future clinical trials of treatments targeting tau protein as early as possible. The data from PI-2620 suggest that it could be an important biomarker of tau pathology in PSP patients. We are excited to be part of this important research."
Dr. Andrew Stephens, Chief Medical Officer at Life Molecular Imaging, added: "The recent clinical data obtained to date with PI-2620 has substantiated its potential as a biomarker to study 4R tau-related diseases like PSP in addition to its previously demonstrated value as biomarker in Alzheimer's disease [3-8]. The research collaboration with UCB helps us to further validate PI-2620 as a biomarker in PSP to support patient selection and improve monitoring of therapeutic efficacy of novel clinical candidates targeting tau."
