NCT05300477
The aim of this randomized, double-blind study is to determine whether erythropoietin (Procrit) and acetazolamide: 1) mitigates altitude-induced decrements in performance at moderate altitude (3,000 m) and 2) mitigates altitude-induced decrements in performance and reduce acute mountain sickness during prolonged exposure to high altitude (4,300 m; 15 days). Volunteers will complete 5 study phases: Phase 1) sea level baseline testing and a moderate altitude exposure; Phase 2) 4 week study intervention - randomly assigned to receive erythropoietin or placebo); Phase 3) 3 1/2 days of acetazolamide and a moderate altitude exposure; Phase 4) high altitude acclimatization - 15 days at Pikes Peak; and Phase 5) two week deacclimatization. Test battery include VO2peak, 3.2 km treadmill time trial, measures of gas exchange and ventilation during rest and exercise, and blood collection.
NCT03585556
Patients with treatment naive wet AMD will receive an intravitreal anti-VEGF injection at Day 0 followed by an intravitreal injection of AAVCAGsCD59 at Day 7. Patients will be followed monthly through Month 12 and receive an intravitreal anti-VEGF injection as needed based on an increase in central subfoveal thickness (CST) of \>50 micrometers on OCT from Day 0, new subretinal hemorrhage on clinical exam, and/or loss of 10 or more ETDRS letters from the previous month exam.
