Voxelotor for Improving Oxygen Saturation in Adults

The purpose of the study is to evaluate the efficacy of voxelotor for increasing oxygen saturation in 20 patients with hypoxemia. Specifically, the SpO2/FiO2 ratio will be compared before and after voxelotor use at rest and during exercise (ambulatory patients only). The primary study objective is to evaluate the efficacy of voxelotor for increasing oxygen saturation in patients with hypoxic hypoxemia as a result of end-stage lung disease or acute lung injury. The secondary objective is to evaluate the efficacy of voxelotor on allowing de-escalation of supplemental oxygen support.
