Specialized procedures are often needed to measure outcomes in cystic fibrosis clinical trials, including laboratory-based measurements, such as sweat chloride, microbiologic endpoints, and biomarkers; and interpretive outcomes, such as multiple breath washout/lung clearance index and nasal potential difference.
Most National Resource Centers (NRCs) fit into one of two frameworks: Service Cores are typically established centers or networks that provide centralized and standardized assays or outcome measures relevant to CF translational and clinical research; and other centers are focused on outcome measure advancement and seek to develop and validate new outcome measures relevant to CF clinical research.
Specialized Services
Personnel at each NRC are available to consult with study sponsors and investigators about the use of these specialized CF outcome measures and provide related support for specific studies (including for pre-clinical and translational research).
Services offered may include, but are not limited to:
- Performance of central testing, interpretation, and/or data analysis
- Assistance with selection of appropriate CF outcome measures
- Consultation on outcome measure implementation
- Assistance selecting and evaluating contract research organizations, both academic and commercial
- Training, qualification, and ongoing support of study site operators
Contacting the NRCs early in the study development process can help make study setup more efficient and ensure more timely and cost-effective completion of studies.

NRC Cores
Advancement of the Center for CFTR Detection
The Advancement of the Center for CFTR Detection (CCD) to support CF therapeutic development specializes in the development and upkeep of harmonized standard operating procedures (SOPs), training, performance, and interpretation of nasal potential difference traces and other measures of CFTR detection in CF clinical trials.
The CCD has been a key resource in the standardization and training in potential difference (PD) measurements. Through extensive experience with clinical research, the CCD has established algorithms that make multi-center data collection feasible for recent and ongoing therapeutic trials. Finally, the center supports referrals for collections and bioreposition of clinical tissue samples from people with CF with rare and other CFTR variants to support pre-clinical development of nucleic acid-based therapies (NABT).

- Detecting mature CFTR protein
- Localizing CFTR in tissues via immunostaining
- Analyzing CFTR mRNA expression and distribution
- Measuring CFTR ion channel activity
The MACE NRC will support rigorous evaluations of NABT, speeding their development and approval to expand treatment options for all people with CF.
