What is the new FDA approved drug for cystic fibrosis?

Excuse me, could you please elaborate on the recent announcement regarding the new FDA-approved drug for cystic fibrosis? I'm particularly interested in understanding the mechanism of action of this medication, its potential benefits for patients, and any potential side effects or considerations that individuals with this condition should be aware of before starting treatment. Additionally, I'd appreciate any information you may have on the clinical trials that led to its approval and the timeline for its availability on the market. Thank you for your time and expertise.
