Laronde is building a company fueled by modular Endless RNA (eRNA) platform. This closed-loop, circular RNA can develop potential eRNA-based therapies capable of treating various diseases in humans. Laronde was founded by Flagship Labs, the innovation foundry of Flagship Pioneering. The company is rapidly scaling to support the parallel development of multiple programs across many disease areas.

It is persistent, non-immunogenic, allows for repeat dosing, and offers flexibility in formulation and delivery.
