Abstract:

Rationale: Since the combination of the corrector Lumacaftor (LUM) with the potentiator Ivacaftor (IVA) has been approved, no reports about the long-term effects of CFTR modulators on exercise endurance and exertional symptoms are available. Methods: We performed a symptom-limited constant load cycling test with assessments of inspiratory capacity, dyspnea and leg discomfort ratings pre- and post 6 months initiation of LUM/ IVA in three patients with Cystic Fibrosis (CF). Results: Exercise endurance time improved by +87% in patient 1, +52% in patient 2 and +23% in patient 3. There was an improvement in inspiratory capacity prior to exercise (+17%, +16%, +6% in patient 1, patient 2 and patient 3, respectively) and at end-exercise (+4%, +23%, +10% in patient 1, patient 2 and patient 3, respectively), associated with improvements in exertional dyspnea and leg discomfort. Conclusion: Endurance time, inspiratory capacity and exertional symptoms improved after 6 months of LUM/IVA.
