inability of us, PARI Pharma GmbH or our other third-party manufacturers to comply with regulatory requirements related to ARIKAYCE or the Lamira® Nebulizer System (Lamira); our inability to obtain and maintain adequate reimbursement from government or third-party payors for ARIKAYCE or, if approved, brensocatib or TPIP or acceptable prices for ARIKAYCE or, if approved, brensocatib or TPIP;

failure to successfully predict the time and cost of development, regulatory approval and commercialization for novel gene therapy products; failure to successfully conduct future clinical trials for ARIKAYCE, brensocatib, TPIP and our other product candidates and our potential inability to enroll or retain sufficient patients to conduct and complete the trials or generate data necessary for regulatory approval of our product candidates or to permit the use of ARIKAYCE in the broader population of patients with Mycobacterium avium complex lung disease, among other things;
