New drug cocktail aims to ease dual Heart-Lung condition

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Participation in another clinical trial involving administration/application of an investigational medicinal product or medical device within 3 months prior to screening \<Baseline Visit (Visit 2)\> 1. Participants who, upon re-confirmation of inclusion/exclusion criteria at the baseline visit, have any disqualifying condition 2. Any other condition that, in the opinion of the investigator, makes the participant unsuitable for participation in this clinical trial
