Just hours after Sen. Wendy Davis announced proposed legislation to reform the Cancer Prevention and Research Institute of Texas, the state’s top three lawmakers are called a moratorium future grants.

In a letter to the state agency’s oversight committee, Gov. Rick Perry, Lt. Gov. David Dewhurst and Texas House Speaker Joe Straus are called on CPRIT to “fully address concerns that have been raised about its organization before any future grants are awarded.”

CPRIT is currently the subject of three investigations. Most recently, the Travis County District Attorney’s Public Integrity unit announced it was investigating an $11 million grant awarded to the Dallas based Peleton Theraputics. An independent audit found CPRIT awarded the grant without the required scientific review.

State leaders are now calling on the agency to cooperate with the current reviews and implement recommended changes to its practices before any more grants are awarded.
