ABSTRACT
Objectives: To compare the current and potential availability of treatments for seven index ultra-rare respiratory diseases before and after the peak of the COVID-19 pandemic. Method(s): At the 2019 ISPOR EU Conference, a landscape review of available treatments for ultra-rare respiratory diseases was presented. Therefore, 3 years on, we sought to explore if treatment access has improved for ultra-rare respiratory diseases. A landscape review was undertaken to seek evidence of treatment developments for ataxia telangiectasia (AT), lymphangiomatosis (LYMF), pulmonary alveolar proteinosis (PAP), pleuroparenchymal fibroelastosis (PPFE), pulmonary alveolar microlithiasis (PAM), pulmonary dendriform ossification (PDO), and light chain deposition disorders (LCDD). Information from clinicaltrials.gov, orpha.net, the EMA and FDA archives and websites of five health technology assessment (HTA) bodies was narratively synthesised. Result(s): The 2019 clinicaltrials.gov search identified 24 studies and the 2022 search 25 studies at various stages of the clinical trial process. They concerned PAP (2019/2022: 11/10), AT (6/10), LCDD (5/4), LYMF (1/0) and PPFE (1/1). No studies were identified for PAM or PDO. The 2019 review found treatments for AT and PAP were granted orphan status by the EMA and the FDA, and in 2021 the FDA granted orphan status to another AT treatment. Neither search found reimbursement submissions for any of the ultra-rare respiratory disease. Conclusion(s): There still remains an obvious lack of proven and available treatments for ultra-rare respiratory diseases. Over the past 3 years, only 1 new treatment has been granted regulatory approval and no treatments have yet to result in therapies that are licensed or approved by HTA bodies. It is our hope that as we enter the post-pandemic world, we as industry professionals and researchers start to adequately address the treatment needs of people living with these debilitating conditions.
