Each participant will be given Trikafta for approximately four weeks. The study researchers will monitor clinical endpoints that include forced expiratory volume (FEV1) and sweat chloride. Additionally, the researchers will obtain skin biopsy material and/or blood sample from each subject so that induced pluripotent stem (iPS) cells can be modified into airway cell monolayers and tested for response to Trikafta. In this way, the study will evaluate an emerging and readily accessible in vitro endpoint as a predictor of clinical response. This study will serve as a pilot/test case for other clinical protocols relevant to patients with rare CFTR variants who do not currently receive modulator therapies.', 'detailedDescription': 'Cystic Fibrosis (CF) is a life threatening genetic disorder resulting from mutations found in the gene known as the cystic fibrosis transmembrane conductance regulator (CFTR). Defects in this gene prevent correct chloride and bicarbonate transport in and out of cells. It has become increasingly important to develop new in vitro model systems capable of predicting in vivo clinical effectiveness of modulator therapy among patients with CF. This objective represents a significant and unmet need for advancing personalized therapeutics in the disease.\n\nTrikafta is currently approved for patients with CF carrying at least one copy of the common F508del variant and over 250 other CFTR abnormalities. Because approximately 90% of CF patients in the United States meet these criteria, pharmacotherapies (Trikafta in particular) are now available to a sizable majority of those with the disease. However, thousands of patients harboring relatively common variants will remain without effective drug therapy. Others with ultra-rare or private CFTR mutations have forms of the disease that are very likely to benefit from available drugs, but do not have access to these therapies. It has been estimated that over 1,000 CFTR mutations are represented by less than 5 patients each. Establishing processes so that individuals with very rare and/or poorly characterized alleles can gain access to effective modulator treatment remains one of the predominant challenges in the field.\n\nThis clinical study will enroll 42 participants without the F508del mutation, carrying partial function or N1303K mutations not approved for Trikafta. Substudy 1 will comprise an open-label, two center trial of orally administered elexacaftor, tezacaftor and ivacaftor (Trikafta) that will enroll 22 patients with rare/orphan genotypes. Substudy 2 will enroll 20 participants who encode the N1303K variant as emblematic of a mutation not approved for Trikafta, but are likely to respond to the treatment.\n\nEach participant will have clinical and/or preclinical evidence that Trikafta should offer benefit, and each will be given Trikafta for approximately four weeks. The researchers will monitor clinical endpoints that include FEV1, sweat chloride, quality of life, and weight. The study will differentiate iPS cells from each subject to generate airway epithelial monolayers that can be tested for response to Trikafta. This trial will serve as a pilot/test case for other clinical protocols relevant to patients with rare CFTR variants and evidence of residual function who do not have an approved modulator therapy, due to rarity of their mutation. It is hypothesized that a correlation will be established between in vitro Trikafta responsiveness of iPS cells and in vivo benefit (FEV1) in patients, and provide a tool for utilizing iPS cells to identify rare CF patient populations most suitable for cystic fibrosis modulator therapy.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'minimumAge': '12 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Provision of signed and dated informed consent form or assent form\n* Stated willingness to comply with all study procedures and availability for the duration of the study\n* Male or female age ≥12\n* A clinical diagnosis of CF or CFTR-related disease and either: 1) evidence for a partial function mutation not currently covered or likely to be covered for treatment with a CFTR modulator (Substudy 1), or 2) N1303K CFTR and a minimal function mutation (Substudy 2)\n* Sweat Chloride \\< 80 mmol/L and/or pancreatic sufficiency (no exogenous pancreatic enzyme supplement therapy) or carrying the N1303K CFTR variant\n* Able to perform spirometry meeting American Thoracic Society (ATS) criteria for acceptability and repeatability\n* Clinically stable in the past 4 weeks with no evidence of CF exacerbation (prior to screening and study Day 1)\n* Willingness to use at least one form of acceptable birth control including abstinence or condom with spermicide.
