LoQus23 Therapeutics Ltd Information

LoQus23 is a biotech company based in Cambridge, UK, developing small molecule somatic expansion inhibitors for the treatment of Huntington’s Disease and other triplet repeat expansion diseases. Huntington’s disease is an autosomal dominant neurodegenerative disorder for which there is currently no disease modifying treatment available and which currently has 30,000 patients in the US alone. LoQus23’s approach has the potential to stop DNA instability and therefore slow neurodegeneration in these diseases. LoQus23 is focused on using a structure-based approach to design small molecule drugs, which can offer more convenient administration than other approaches. Oral small molecule drugs have a strong track record in treating complex brain diseases and provide greater convenience for patients compared with other advanced treatment modalities. LoQus23’s lead programme, a potent allosteric small molecule MSH3 inhibitor, part of the MutSβ complex, will enter the clinic in 2026. LoQus23 has a highly experienced leadership team, built on world-class science. It was originally established in 2019 by Dr David Reynolds, Dr Caroline Benn, and Dr Ruth McKernan CBE, FMedSci, Entrepreneurs in Residence at SV Health Investors’ Dementia Discovery Fund, which also acted as the initial seed investor. In October 2024, the Company closed a successful £35 million Series A financing round led by Forbion, alongside existing investors SV Health Investors’ Dementia Discovery Fund and Novartis Venture Fund.
