Flagship Pioneering, the company-creating venture fund that launched Moderna Inc. in 2012, is betting $50 million on a new twist in RNA-focused development at Laronde Inc. Leveraging its explorations of the therapeutic applicability of long non-coding RNA, Flagship CEO Noubar Afeyan said the company has created Endless RNA (eRNA), "a new class of medicines that can be programmed to persistently express therapeutic proteins in the body, at tunable levels."
