- W2894489394 abstract "Objective: To characterize the pulmonary safety of CVT-301 84 mg vs standard-of-care over 12 months. Background: CVT-301 is an investigational therapy that delivers levodopa to the lungs. It is intended to treat OFF period symptoms in patients with Parkinson’s disease (PD) on an oral levodopa/dopa-decarboxylase inhibitor regimen. Design/Methods: A prospective, 12-month, open-label, randomized, controlled study of PD subjects experiencing motor fluctuations. Eligible subjects were randomized 2:1 to CVT-301 84 mg or to an observational cohort receiving oral standard-of-care. Major inclusion criteria: ability to perform spirometry in the ON/OFF states, screening forced expiratory volume in 1 second (FEV 1 ) ≥50%, and FEV 1 /forced vital capacity (FVC) ratio >60% in the ON state. Pulmonary safety was assessed using spirometry (FEV 1 , FVC, FEV 1 /FVC) and diffusion capacity of the lungs for carbon monoxide (DLco) assessments at screening, randomization (baseline), and at approximately 1, 3, 6, 9, and 12 months. Results: 408 subjects were randomized: 278 to CVT-301 and 130 to the observational cohort. In the CVT-301 group, 204 completed the study. Mean (SD) baseline characteristics for the CVT-301 group included: age 63.6 (8.5) years, PD duration 9.0 (4.8) years, daily OFF time 5.6 (2.0) hours/day, and number of OFF periods 3.6 (1.1)/day. Overall, the average number of CVT-301 doses was 2.3 (0.9)/day. The mean change (SD) from baseline in FEV 1 at week 52 was −0.117 L (0.214) for the observational cohort and −0.105 L (0.209) for the CVT-301 group. Similarly, there were no notable differences between CVT-301 and the observational cohort in the other spirometry parameters. Conclusions: Exposure to CVT-301 84 mg for up to 12 months did not alter the natural progression of pulmonary function, as shown by the spirometry and DLco assessments in a comparable observational cohort treated with oral PD medications.
