Xellsmart Biopharmaceutical (Suzhou) Co. Ltd. has announced IND clearances by the FDA for its XS-411 and XS-228 cell therapies, for Parkinson’s disease and amyotrophic lateral sclerosis (ALS), respectively.

Genes associated with lysosomal dysfunction increase the risk of Parkinson’s disease (PD), according to a study led by scientists at Northwestern University. The discovery also explains why some people who carry a pathogenic variant of the GBA1 gene develop PD or dementia with Lewy bodies (DLB) and others do not. The key lies in the Commander complex, involved in the transport of proteins to this organelle. This discovery raises the need for combinatorial therapies that act on more than one pathway for this type of neurodegenerative disorder.

1st Biotherapeutics Inc. has joined The Michael J. Fox Foundation for Parkinson’s Research (MJFF) LRRK2 Investigative Therapeutics Exchange (LITE) program.

Researchers from AC Immune SA recently presented the discovery of ACI-21018, a novel α-synuclein aggregation inhibitor developed using AC Immune’s proprietary Morphomer platform.

Researchers from Sanofi SA reported the preclinical characterization of SAR-446159 (ABL-301), a bispecific antibody construct comprising an antibody targeting α-synuclein fused to an engineered antibody fragment that targets IGF-1R and functions as a blood-brain barrier (BBB) shuttle, known as the Grabody-B platform.

BDNF is the brain’s most abundant neurotrophic factor, playing a key role in neuronal survival and synaptic plasticity through the activation of the transcription factor CREB, which is essential for driving beneficial effects in neurons. CREB is downregulated in Parkinson’s disease, Huntington’s disease, frontotemporal dementia, Alzheimer’s disease and other neurodegenerative conditions.

ABL Bio Inc. announced April 7 that it sealed a potential £2.075 billion (US$2.65 billion) license deal with GSK plc, granting GSK global rights to use ABL’s blood-brain barrier (BBB) penetrating bispecific antibody platform, Grabody-B, to develop multiple programs in the neurodegenerative disease arena. Under the terms signed April 5, ABL agreed to transfer Grabody-B-related technology and know-how to GSK, upon which GSK will assume responsibility for preclinical and clinical development, manufacturing and commercialization.
