Drugmakers Moderna and AstraZeneca are partnering up to develop a “mRNA therapeutic” to treat life-threatening cardiovascular disease such as heart failure.

“We are collaborating with @AstraZeneca on an mRNA therapeutic (AZD8601) that encodes for VEGF-A to promote recovery of cardiac function through tissue regeneration,” Moderna said in a Twitter post Thursday.

The biotechnology company included a link to a phase two study dated Nov. 15, 2021, that analyzed messenger RNA treatment in patients undergoing coronary artery bypass grafting surgery. That study produced “positive” results, Moderna said.
