About

This is an open-label, multicenter, single-group study designed to determine the effectiveness of Mucinex® when used by patients to treat SCB over a 12-week period, following a 2-week run-in period of no treatment (to establish a baseline).

Full description

Data will be collected via the Vitaccess Real[TM] platform from adult patients with SCB and HCPs based in the US. During the 12-week period of receiving treatment, patient participants will take Mucinex® 12h, 2 x 600 mg (1200 mg total) twice daily and complete weekly bespoke surveys and the CASA-Q instrument. Patient-reported data will include prior usage of Mucinex®, treatment compliance, treatment satisfaction, and symptoms.

During this same period of time, HCPs will report treatment satisfaction via electronic case report forms (eCRFs), and will also have the ability to spontaneously report any treatment-emergent adverse events.

  • Patients who have chronic sputum production 3 months out of the year for 2 consecutive years and a productive cough as part of their symptoms.
  • Patients who understand and are able to fill out a questionnaire and ePRO weekly
  • Patients who have not used guaifenesin containing products within one month of the time of study enrollment
  • Patients with 6 to 12 (ideally 12)-month historical data - retrieved from either electronic medical records (EMR), electronic health records (EHRs), or provided by the patient via interview.

Rescue medicine:

Exclusion criteria

  • Patients who are pregnant or breastfeeding
  • Participation in another study involving an investigational product within 30 days of the baseline visit
  • Pulmonary diagnosis other than CB, (such as cystic fibrosis, alpha-1 antitrypsin deficiency, bronchiectasis, or pulmonary fibrosis)
