Endpoints for clinical trials in lung disease could be better…

FEV1 and FVC are relatively blunt tools for getting a complete picture of a disease state – they do not provide information on the pulmonary microenvironment.
Inflammation is a hallmark of chronic lung diseases and an important piece of the bigger picture to understand when evaluating effectiveness of a drug
Decreasing lung-specific inflammation is a key strategy for pharmaceutical targets
Mechanistic markers of inflammation, such as these, can be detected earlier and indicate sub-clinical improvements in outcomes which help drive decision making during the drug design and clinical trial process

ADD DETAIL to a drug’s storyline with accurate and lung-specific measurements of inflammation by measuring neutrophil elastase (NE) and proteinase 3 (PR3) in sputum.

ProAxsis offers products that are proven to be valuable in enrolling participants, stratifying results, and measuring effectiveness of respiratory drugs in development. The ready- to -use kits offer sensitive, reliable, and accurate read-outs of NE and PR3 activity in sputum or broncheoalveolarlavage (BAL) fluid. NE and PR3 activity levels have been shown to correlate with disease severity, time to next exacerbation, and bacterial load. They can be more globally seen as mechanistic markers of a neutrophilic-driven inflammatory state.

DiaPharma offers assays from ProAxsis using ProteaseTag™ technology:

Neutrophil Elastase Activity Immunoassay – quantitative 96-well kit
Proteinase 3 Immunoassay (PR3) – quantitative 96-well kit
NEATstik Neutrophil Elastase – semi-quantitative lateral flow kit
