# Five Biotech Companies Advancing Therapeutic Solutions for Cystic Fibrosis
Cystic fibrosis (CF) is a life-threatening genetic disorder that primarily affects the lungs and digestive system. It is caused by mutations in the **CFTR (Cystic Fibrosis Transmembrane Conductance Regulator)** gene, which leads to the production of thick, sticky mucus that can clog airways and trap bacteria, resulting in chronic infections and lung damage. Over the past few decades, significant advancements in biotechnology have led to the development of innovative therapies that target the underlying causes of CF, rather than just managing its symptoms.
In this article, we will explore five leading biotech companies that are at the forefront of developing therapeutic solutions for cystic fibrosis, offering hope to patients and their families.

## 1. **Vertex Pharmaceuticals**
### Overview:
Vertex Pharmaceuticals is widely regarded as a pioneer in the development of CF therapies. The company has been instrumental in transforming the treatment landscape for cystic fibrosis by focusing on therapies that target the defective CFTR protein.
### Key Contributions:
– **Kalydeco (Ivacaftor)**: Approved in 2012, Kalydeco was the first drug to treat the underlying cause of CF in patients with specific mutations in the CFTR gene. It works by improving the function of the defective CFTR protein.
– **Orkambi (Lumacaftor/Ivacaftor)**: Approved in 2015, Orkambi is a combination therapy that targets patients with two copies of the F508del mutation, the most common CF mutation.
– **Symdeko (Tezacaftor/Ivacaftor)**: Approved in 2018, Symdeko is another combination therapy that expands treatment options for patients with different CFTR mutations.
– **Trikafta (Elexacaftor/Tezacaftor/Ivacaftor)**: Approved in 2019, Trikafta is a triple-combination therapy that has been a game-changer for CF patients. It is effective in treating up to 90% of people with CF, including those with at least one F508del mutation.
### Impact:
Vertex’s therapies have significantly improved lung function, reduced pulmonary exacerbations, and enhanced the quality of life for many CF patients. Trikafta, in particular, has been hailed as a breakthrough, offering treatment to a broader range of patients than ever before.

## 2. **AbbVie**
### Overview:
AbbVie, a global biopharmaceutical company, has been involved in the development of CF therapies through its collaboration with **Galapagos NV**, a Belgian biotech company. Together, they are working on novel CFTR modulators that aim to improve the efficacy of existing treatments.
### Key Contributions:
– **GLPG2737**: This is a CFTR corrector that is being developed in combination with other CFTR modulators to enhance the function of the CF
