Randomised controlled trial for emphysema with a selective agonist of the gamma-type retinoic acid receptor
(2012) In European Respiratory Journal 40(2). p.306-312- Abstract
- Palovarotene is an oral gamma-selective retinoid agonist. In animal emphysema models, palovarotene reduced inflammation, promoted structural repair and functional improvement. REPAIR (Retinoid treatment of Emphysema in Patients on the alpha(1)-antitrypsin International Registry), was an investigator-initiated, double-blind, placebo-controlled randomised study to assess the safety and efficacy of 5 mg.day(-1) palovarotene given for 1 year to 262 patients with severe alpha(1)-antitrypsin deficiency and emphysema confirmed by computed tomography. Change in volume-adjusted 15th percentile point lung density from baseline in 1 year was the primary endpoint; functional end-points were also regularly assessed. We randomly assigned 133 and 129...

Change in volume-adjusted 15th percentile point lung density from baseline in 1 year was the primary endpoint; functional end-points were also regularly assessed. We randomly assigned 133 and 129 patients to placebo or palovarotene, respectively. Both groups were well matched for all baseline characteristics, including respiratory medications. 88% and 85% of patients completed 1 year of treatment with placebo and palovarotene, respectively. Palovarotene was generally well tolerated. In the study completers population, the placebo-corrected difference of lung density was -0.45 HU at week 28 (p=0.64) and -0.25 HU at week 52 (p=0.94). A nonsignificant treatment difference in most functional parameters of the lung in favour of the drug was observed over time suggesting potential pharmacological effects of palovarotene. Palovarotene 5 mg.day(-1) over 1 yr failed to show a significant benefit on lung density in moderate-to-severe emphysema secondary to severe alpha(1)-antitrypsin deficiency. (Less)
