The U.S. Food and Drug Administration today approved a new drug that tackles the underlying cause of cystic fibrosis (CF) in 4 percent of patients. The drug, called ivacaftor (brand name Kalydeco), acts by helping the body make better use of a protein that works incorrectly in cystic fibrosis patients.

The underlying research behind this and other drugs that may help even more individuals with cystic fibrosis was the subject of a feature length article, which I edited, called "A Breath of Fresh Air" [preview], and which appeared in the August 2011 issue of Scientific American.

Two things really intrigued me about the work:

1) the incredible way that the CF community has pulled together to prolong lives and improve quality of life for folks with the condition based on solid science, preventive care and smart nursing (by professionals and others)

2) although CF is a genetic condition, the research does not depend on gene therapy--which has had its ups and downs over the past couple of decades. Rather, researchers are trying to come up with drugs that help make the defective protein responsible for cystic fibrosis more effective.

With any luck, ivacaftor will be only the first of several new CF drugs--each designed to counter a different fundamental cause of the condition. Welcome to the era of personalized medicine.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,
