LoQus23 Therapeutics Ltd (“LoQus23”), a private biotechnology company investigating small molecule drugs that could stop DNA instability and slow neurodegeneration in Huntington’s Disease, myotonic dystrophy type 1 and similar triplet repeat expansion diseases, today announces the successful close of its £35 million (c.$43 million) Series A financing. The financing round was led by Forbion, alongside existing investors SV Health Investors’ Dementia Discovery Fund (DDF) and Novartis Venture Fund (NVF). Forbion General Partner Rogier Rooswinkel will join LoQus23’s Board of Directors.
LoQus23 was founded in 2019 by Entrepreneurs in Residence at DDF Dr David Reynolds, Dr Caroline Benn, and Dr Ruth McKernan CBE, FMedSci and seeded by SV’s Dementia Discovery Fund. It received additional seed funding from NVF in 2021. The Company has since established a platform of assays and a small molecule series of MutSa and MutSß inhibitors which are therapeutically relevant in up to 30 triplet repeat diseases, including Huntington’s Disease.
The Mismatch Repair (MMR) branches of the DNA Damage Repair (DDR) system repair DNA insertions, deletions and misincorporation errors during transcription and/or cellular replication, with two main pathways dependent upon the size of mismatch – MutSa for small mismatches and MutSß for larger insertion / deletion loops.
Huntington’s disease is an autosomal dominant neurodegenerative disorder for which there is currently no disease modifying treatment available and which has 30,000 patients in the US alone. By targeting somatic expansion, LoQus23 is hoping to slow or even halt the onset and progression of Huntington’s disease, a concept supported by genetic studies and recently strengthened by pre-clinical models.
The proceeds of the Series A financing will be primarily used to support the pre-clinical development and initial clinical studies of LoQus23’s lead programme, an allosteric small molecule MutSß inhibitor. The Company is preparing its lead programme to enter the clinic in 2026.
Dr David Reynolds, Chief Executive Officer of LoQus23 Therapeutics, said: “This financing will enable us to develop key clinical data to support the development of our exciting lead programme. The ever-increasing body of data pointing to somatic expansion, caused by aberrant DNA mismatch repair, as being the primary culprit in Huntington’s disease provides great support that our approach of developing oral small molecule therapies will be transformative for patients with this dreadful inherited disease. We welcome Forbion as the lead investor of this round, alongside our existing high calibre investors, and look forward to benefiting from their support and expertise.”
Rogier Rooswinkel, General Partner at Forbion and newly appointed Board Member of LoQus23, commented: “Somatic expansion is a key driver of triplet repeat diseases like Huntington’s. In somatic expansion, MutSß seems the most promising and best validated target, with the potential to bring disease progression to a halt. LoQus23 is leading the charge in developing allosteric small molecules against MutSß, and we look forward to working with them to progress their molecules towards the clinic and ultimately to benefit patients.”

Notes to Editors
DDR System
The DDR system is a complex set of pathways involving more than 400 genes/proteins, which is required for long-term maintenance of an organism’s DNA to promote cellular health throughout a lifetime of damaging events.
MMR
MutSa and MutSß are part of the MMR system, which is heavily implicated by human genetic and mechanistic studies to be the root cause of Huntington’s disease and other related triplet repeat diseases. It is now clear that the initial driver of disease pathophysiology is MMR-mediated CAG repeat expansion in the Huntingtin gene, a process known as somatic expansion. Once a critical threshold number of CAG repeats is reached, then the second phase of neuronal dysfunction and ultimately death follows, which causes the slowly progressing symptoms in patients.
About LoQus23 Therapeutics Ltd
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 disorders. 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 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.
