AstraZeneca, Author Interviews, NEJM, Pulmonary Disease / 29.06.2020 Interview with: Frank Trudo, MD MBA Vice President, US Medical Affairs Respiratory & Immunology AstraZeneca What is the background for this study? Response: ETHOS is a randomized, double-blinded, multi-center, parallel-group, 52-week trial to assess the efficacy and safety of PT010 in symptomatic patients with moderate to very severe COPD and a history of exacerbation(s) in the previous year. Outcomes in the ETHOS trial included, as a primary endpoint, the rate of moderate or severe exacerbations. How does PT010 differ from other treatments for COPD?
  • Highly competitive: PT010’s Phase III clinical trial program demonstrates it has a highly competitive clinical profile in decreasing moderate or severe exacerbations. Severe exacerbations were defined as exacerbations leading to hospitalization or death.
  • All-cause mortality: In a secondary endpoint, PT010 showed a 46% reduction in the risk of all-cause mortality compared with glycopyrronium/formoterol fumarate. The data from ETHOS show that reducing risk of all-cause mortality is achievable for patients with this progressive disease and could transform treatment goals in COPD.
  • Two potential dose options: This is also the first time we have seen the benefit of closed triple-combination therapy at two ICS doses, which could transform care by allowing physicians to select the optimal dosing option for individual patients.

David R. Ziehr B.S., MD Candidate Harvard Medical Interview with: David R. Ziehr B.S., MD Candidate Harvard Medical School Medical Research: What is the background for this study? What are the main findings? Response: Androgen deprivation therapy (ADT), commonly achieved with gonadotropin-releasing hormone agonists or antagonists, is a mainstay of prostate cancer therapy. While randomized controlled trials demonstrate that ADT improves survival among men with unfavorable risk prostate cancer, retrospective studies have suggested that some men with comorbid illnesses such as heart disease may not derive a benefit from—or may even be harmed by—ADT. However, the nature of this harm has not been characterized. We studied over 5000 men with prostate cancer who were treated with brachytherapy (implanted radioactive seeds) with or without ADT. We analyzed the men based on pre-treatment cardiac comorbidity and examined the association between ADT and death from cardiac causes. We found that among men with congestive heart failure or a past myocardial infarction (MI), Androgen deprivation therapy was associated with a three-times greater risk of death from heart disease. However, Androgen deprivation therapy was not associated with greater risk of cardiac mortality in men without heart disease or with a risk factor for heart disease, such as diabetes, hypertension or hyperlipidemia.
