Parents say son with autism was nonverbal until trying an off-label drug that treats chemo side effects

Caroline Connor's concerns about her son Mason's development began around his first birthday, when she noticed he wasn't talking or using any words. Their pediatrician didn't seem worried, but the speech delay persisted. At 2 and a half, Mason was diagnosed with autism.

The Connors went on a mission, searching for anything that would help.

"We just started researching on our own. And that's when my husband Joe came across Dr. Frye in a research study he was doing," Caroline said.
