Abstract

Asthma is a heterogeneous disease, with multiple underlying inflammatory pathways and structural airway abnormalities that impact disease persistence and severity. Recent progress has been made in developing targeted asthma therapeutics, especially for subjects with eosinophilic asthma. However, there is an unmet need for new approaches to treat patients with severe and exacerbation-prone asthma, who contribute disproportionately to disease burden. Extensive deep phenotyping has revealed the heterogeneous nature of severe asthma and identified distinct disease subtypes. A current challenge in the field is to translate new and emerging knowledge about different pathobiologic mechanisms in asthma into patient-specific therapies, with the ultimate goal of modifying the natural history of disease. Here, we describe the Precision Interventions for Severe and/or Exacerbation-Prone Asthma (PrecISE) Network, a groundbreaking collaborative effort of asthma researchers and biostatisticians from around the United States. The PrecISE Network was designed to conduct phase II/proof-of-concept clinical trials of precision interventions in the population with severe asthma, and is supported by the National Heart, Lung, and Blood Institute of the National Institutes of Health. Using an innovative adaptive platform trial design, the PrecISE Network will evaluate up to 6 interventions simultaneously in biomarker-defined subgroups of subjects. We review the development and organizational structure of the PrecISE Network, and choice of interventions being studied. We hope that the PrecISE Network will enhance our understanding of asthma subtypes and accelerate the development of therapeutics for severe asthma.

Keywords: Severe asthma; adaptive clinical trial design; asthma exacerbation; biomarker; non–type 2 asthma; patient advisory committee; precision medicine; type 2 asthma.

PrecISE study structure. The study structure has 3 phases. First, during an 8-week initial screening phase and run-in period, subjects undergo screening and adherence monitoring, assessment of predictive biomarkers and phenotyping, followed by treatment assignment based on biomarkers and safety considerations. Second, subjects enter the double-blind, placebo-controlled cross-over phase followed by washout. The second phase varies between 48 and 64 weeks, depending on the washout duration. Finally, during the multiperiod cross-over phase, subjects can be randomized to up to 4 additional interventions. Reprinted with permission from Israel et al.

Mitochondrial metabolism is connected through biochemical pathways with arginine/NO metabolism, which is a biomarker of asthma inflammation. The TCA pathway is linked to the arginine-citrulline cycle, which gives rise to NO. Arginase 2 (ARG2) is increased in asthmatic airway epithelial mitochondria, and feeds arginine into the TCA cycle via ornithine to alpha-ketoglutarate (aKG) to enter TCA and increase electron transport chain (ETC) for energy production. The acceleration of the TCA cycle leads to intermediates that dampen proinflammatory signal transduction. MCTs freely diffuse into the mitochondria, are oxidized rapidly, and feed acetyl-CoA into the TCA cycle. MCT may be protective against inflammation related to metabolism in those individuals with greater arginine metabolism as determined by FENO.

The endogenous anti-inflammatory molecule GSNO is broken down by GSNOR in many patients with asthma. These patients can often be identified by genotype. Because of its effect to increase β2-receptor expression, it is anticipated that precision therapy with the GSNOR inhibitor, Cavosonstat, will improve β2 responsiveness in addition to improving lung function and reducing inflammation.
