Researchers are closer to finding a drug that may cure a disease affecting hundreds of Oklahomans.

One metro doctor is not only affected by cystic fibrosis, but has insight on a potential cure.

Dr. Mark Harvey's children, Will and Lauren, both have cystic fibrosis. The disease affects the lungs and digestive system.  

"We've not really had any type of medicine that actually - that could eliminate the disease process," he said.

Now the heart doctor wants everyone to know about the cause that is close to his heart. He's getting plenty of support from others who want to help find a cure. 

Suzanne LaBelle is playing a big part in raising money for cystic fibrosis research. She recently organized her third annual tennis tournament to raise awareness of the disease.

"They are very close to us and we are passionate about this and thankful to our tennis community," said LaBelle said.

The funds benefit the Cystic Fibrosis Foundation, Dr. Harvey said.

"The Cystic Fibrosis Foundation, through research, actually has therapy that may actually treat this disease," Harvey said.
