Lachesis BioSciences is a clinical-stage biotechnology company targeting dementia caused by Alzheimer’s and Parkinson’s disease. Lachesis Biosciences is developing LBIO-R32, a rivastigmine nasal spray for the treatment of mild to severe Alzheimer's disease dementia and mild to moderate Parkinson’s disease dementia. Lachesis is pursuing a 505(b)(2) development pathway for LBIO-R32, which means the company can substantially rely on existing preclinical and clinical data generated by Novartis with rivastigmine for approval. From a development standpoint, this takes years and hundreds of millions off their plate. It's a significantly de-risked and expedited approach.
