New treatment option for Alpha 1-Antitrypsin
Official title Genetic Variation in IgG in Alpha 1 Antitrypsin Deficiency
ClinicalTrials.gov ID: NCT07135427
What this study is testing
What is 20-valent pneumococcal conjugate vaccine?
20-valent pneumococcal conjugate vaccine is an investigational medicine, being studied as a potential treatment for alpha 1-antitrypsin.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The goal of this study is to learn whether patients who have a genetic mutation in the genes that cause alpha 1 antitrypsin deficiency also have genetic variation in nearby genes that can increase risk for reduced immune function and respiratory infections. To investigate this hypothesis, we will compare immune responses to the 20-valent pneumococcal conjugate vaccine (PCV20, Pfizer) between participants who have one abnormal copy of the SERPINA1 gene and either no COPD exacerbations, vs those with 2 or more COPD exacerbations in the past year.
- Phase 4: studies an already-approved treatment
