Arms and Interventions

Arm Intervention/Treatment
Experimental: LUM/IVA

LUM/IVA granules or tablets were administered orally every 12 hours (Participants aged 2 through 5 years received LUM 100 mg/IVA 125 mg granules or LUM 150 mg/IVA 188 mg granules based on body weight. Participants ≥6 years of age were to receive LUM 200 mg/IVA 250 mg tablets). Doses were adjusted upward for changes in weight and age.

Drug: LUM/IVA
Participants received LUM/IVA every q12h.

  • Outcome Measures

    Primary Outcome Measures

    1. Safety as Assessed by Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) [Day 1 up to Week 98]

    Secondary Outcome Measures

    1. Absolute Change in Sweat Chloride [From Parent Study 115B Baseline at Week 96]

      Sweat samples were collected using an approved collection device.

    2. Absolute Change in Body Mass Index (BMI) [From Parent Study 115B Baseline at Week 96]

      BMI was defined as weight in kilogram (kg) divided by height in square meter (m^2).

    3. Absolute Change in BMI-for-age Z-score [From Parent Study 115B Baseline at Week 96]

      BMI was defined as weight in kilograms divided by height in m^2. z-score is a statistical measure to describe whether a mean was above or below the standard. A z-score of 0 is equal to the mean and is considered normal. Lower numbers indicate values lower than the mean and higher numbers indicate values higher than the mean.

    4. Absolute Change in Weight [From Parent Study 115B Baseline at Week 96]

    5. Absolute Change in Weight-for-age Z-score [From Parent Study 115B Baseline at Week 96]

      Z-score is a statistical measure to describe whether a mean was above or below the standard. A z-score of 0 is equal to the mean and is considered normal. Lower numbers indicate values lower than the mean and higher numbers indicate values higher than the mean.

    6. Absolute Change From Baseline in Stature (Height) [From Parent Study 115B Baseline at Week 96]

    7. Absolute Change in Stature-for-age Z-score [From Parent Study 115B Baseline at Week 96]

      Z-score is a statistical measure to describe whether a mean was above or below the standard. A z-score of 0 is equal to the mean and is considered normal. Lower numbers indicate values lower than the mean and higher numbers indicate values higher than the mean.

    8. Time-to-first Pulmonary Exacerbation [From Parent Study 115B Baseline through Week 96]

      Pulmonary exacerbation was defined as new or changed treatment with oral, inhaled, or intravenous antibiotics and fulfillment of pre-specified protocol-defined criteria.

    9. Number of Pulmonary Exacerbations (PEx) [From Parent Study 115B Baseline through Week 96]

      Pulmonary exacerbation was defined as new or changed treatment with oral, inhaled, or intravenous antibiotics and fulfillment of pre-specified protocol-defined criteria.

    10. Number of Cystic Fibrosis (CF) Related Hospitalizations [From Parent Study 115B Baseline through Week 96]

    11. Absolute Change in Fecal Elastase-1 (FE-1) Levels [From Parent Study 115B Baseline at Week 96]

    12. Absolute Change in Immunoreactive Trypsinogen (IRT) Serum Levels [From Parent Study 115B Baseline at Week 96]

    13. Number of Participants With Microbiology Culture Status (Positive or Negative) [Week 96]

      Following microbial tests were performed: Burkholderia, Methicillin Resistant Staphylococcus Aureus (MRSA), Methicillin Susceptible Staphylococcus Aureus (MSSA), Pseudomonas Aeruginosa Mucoid (P. Aeruginosa Mucoid), P. Aeruginosa Non-Mucoid, P. Aeruginosa Small Colony Variant and Stenotrophomonas Maltophilia.

    14. Absolute Change in Lung Clearance Index (LCI) 2.5 [From Parent Study 115B Baseline at Week 96]

      LCI 2.5 represents the number of lung turnovers required to reduce the end tidal inert gas concentration to 1/40th of its starting value.

    15. Absolute Change in Lung Clearance Index (LCI) 5.0 [From Parent Study 115B Baseline at Week 96]

      LCI 5.0 represents the number of lung turnovers required to reduce the end tidal inert gas concentration to 1/20th of its starting value.

    • Received at least 4 weeks of LUM/IVA treatment and completed visits up to Week 24 and the Safety Follow-up Visit, if required, of Study 115B but are not taking LUM/IVA at the end of the Study 115B Treatment Period (i.e., Week 24) because of a drug interruption and either did not receive Vertex approval to enroll in the Treatment Cohort or do not want to enroll in the Treatment Cohort.

    • Permanently discontinued LUM/IVA in Study 115B after receiving at least 4 weeks of treatment and remained in the study from the time of treatment discontinuation through the Week 24 Visit and Safety Follow-up Visit, if required.

    Exclusion Criteria (Treatment Cohort Only):

    • Subjects with a history of allergy or hypersensitivity to LUM/IVA.

    • Liver function test (LFT) abnormality meeting criteria for LUM/IVA treatment interruption at the completion of Study 115B, for which no convincing alternative etiology is identified.

    • QTc value at the completion of Study 115B that would pose an additional risk to the subject in the opinion of investigator, and which should be discussed with the Vertex medical monitor

    • History of poor compliance with LUM/IVA and/or procedures in Study 115B as deemed by the investigator.

    • Participation in an investigational drug trial (including studies investigating LUM and/or IVA) other than Study 115B.

    15. Secondary Outcome
    Title Absolute Change in Lung Clearance Index (LCI) 2.5
    Description LCI 2.5 represents the number of lung turnovers required to reduce the end tidal inert gas concentration to 1/40th of its starting value.
    Time Frame From Parent Study 115B Baseline at Week 96

    Outcome Measure Data

    Analysis Population Description
    Study 116 LCI substudy set included all participants who signed the informed consent/assent to the optional LCI substudy and were enrolled and exposed to any amount of study drug in current study 116.
    Arm/Group Title LUM/IVA
    Arm/Group Description LUM/IVA granules or tablets were administered orally every 12 hours (Participants aged 2 through 5 years received LUM 100 mg/IVA 125 mg granules or LUM 150 mg/IVA 188 mg granules based on body weight. Participants ≥6 years of age were to receive LUM 200 mg/IVA 250 mg tablets). Doses were adjusted upward for changes in weight and age.
