Navigating CF parenthood during a new era of the disease
CF life expectancy has improved greatly, but nothing is ever guaranteed

“It’s a great time to be born with cystic fibrosis.”

I remember hearing this sentence from the head nurse during the first clinic of our daughter, Claire. At the time, it felt like they were just words meant to comfort a new cystic fibrosis (CF) mom. Maybe I was jaded because I’d already done a significant amount of research about the disease. That research had given me hope, but it’d also given me a realistic perspective on what we faced.

The reality of CF and life expectancy
While most parents don’t have to live with the nagging thought of their child’s mortality, that’s exactly what CF parents do.

Historically, CF parents received a bleak prognosis along with their child’s diagnosis. Just decades ago, in 1978, a child with CF had a median survival age of 11. And while we were given a far better prediction for life expectancy, there was no avoiding the stark reality of those numbers. 


However, recent advancements in therapeutic treatments have evolved tremendously, even since Claire’s birth just over four years ago. It seems like there’s positive news daily surrounding drug development for cystic fibrosis.

While CF patients born today are expected to live into their 50s, just last month Cystic Fibrosis News Today reported on a study that showed people with CF who begin the newest generation of medications in adolescence may live nearly normal life spans.

This progress is largely due to unprecedented medical breakthroughs and the introduction of highly effective modulators. Modulators are medications that help to increase functionality of the CFTR protein, which is affected by CF-causing mutations in the CFTR gene. To put it simply, these drugs treat CF on a cellular level to mitigate symptoms of the disease.

Modulators have greatly improved the lives of many CF patients. But they’re not a cure, and not everyone with CF has access to them.


The modulator generation
I’ve heard my daughter’s age group referred to as the “modulator generation.” Claire and her peers who are eligible to take a modulator are the children benefiting from these drugs from infancy and toddlerhood. I’m grateful that our daughter has the mutations and resources to access a modulator at such a young age.

But at a time when there’s so much hope for the CF community, I also feel the need to have realistic expectations for Claire’s life. As a lawyer, I analyze risks and liabilities in my professional life daily. For that reason, I consider all the objective data around CF drug developments in the context of how my daughter’s disease is presenting.

It’s hard to know exactly what the outcome will be for those of us with children who started a modulator at a young age. We’re living in unprecedented times with groundbreaking drugs. The generations of people with cystic fibrosis before us didn’t have access to these advancements at such an early stage in life.

But no one truly knows what will happen long term. And those life expectancy numbers aren’t one-size-fits-all. There are still people with CF passing away far too young.


Most days, I don’t think about Claire’s life expectancy. I choose to focus on the positives regarding her future. We have been the fortunate recipients of these modulators that patients, parents, doctors, and scientists worked tirelessly for. Not everyone lived to see these therapeutic drugs come to fruition. But it’s not always an easy choice to focus on the positives when faced with the realities of the disease. There are no guarantees with CF, or with life in general.
