Transposon Therapeutics develops nucleoside reverse transcriptase inhibitors (NRTIs) targeting LINE-1 reverse transcription to mitigate neurodegeneration associated with diseases such as Progressive Supranuclear Palsy and Amyotrophic Lateral Sclerosis. Their lead candidate, TPN-101, aims to reduce neurotoxic pathology linked to increased LINE-1 activity, addressing a critical need for effective treatments in neurodegenerative disorders.

Problem
Neurodegenerative diseases like Progressive Supranuclear Palsy (PSP) and Amyotrophic Lateral Sclerosis (ALS) are associated with increased expression and reverse transcription of LINE-1 elements, leading to neurotoxic pathology and neuronal dysfunction. Current treatments do not effectively target the underlying LINE-1 activity contributing to these conditions. Aicardi-Goutières Syndrome (AGS) is caused by genetic mutations of LINE-1 repressing enzymes, resulting in uncontrolled LINE-1 activation with severe interferon-1 autoimmune reaction.
Solution
Transposon Therapeutics is developing nucleoside reverse transcriptase inhibitors (NRTIs) and Protein Kinase R inhibitors (PKRi) to address LINE-1 associated neurodegenerative diseases. Their lead candidate, TPN-101 (censavudine), is a potent inhibitor of LINE-1 reverse transcriptase with systemic and brain bioavailability, currently in Phase 2a clinical trials for PSP, ALS/FTD, and AGS. By inhibiting LINE-1 reverse transcription, TPN-101 aims to mitigate neurodegeneration and reduce neurotoxic pathology. Transposon is also developing next-generation NRTIs and PKR inhibitors to expand their pipeline and target additional neurological and age-related diseases associated with LINE-1 pathology.
Target Audience
The primary target audience includes patients suffering from neurodegenerative diseases such as Progressive Supranuclear Palsy (PSP), Amyotrophic Lateral Sclerosis (ALS), Frontotemporal Dementia (FTD), and Aicardi-Goutières Syndrome (AGS), as well as those with other LINE-1 associated neurological and age-related diseases.
