November 17, 2016 updated by: Nivalis Therapeutics, Inc.

A Phase 2, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study of N91115 for Efficacy and Safety in Patients With CF Heterozygous for F508del-CFTR + Gating Mutation Being Treated With Ivacaftor

Cavosonstat (N91115) is being studied as a potential novel therapy for cystic fibrosis (CF), and this study assesses a target population of patients who are heterozygous for F508del-CFTR and a gating mutation that is approved for treatment with ivacaftor (G551D, G1244E, G1349D, G178R, G551S, S1251N, S1255P, S549N, or S549R).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The absolute change in ppFEV1 in the N91115 treated group
Time Frame: Baseline, week 4 and 8 assessments
Forced Expiratory Volume (FEV) absolute measurements comparing baseline to after 4 and 8 weeks of N91115 treatment. FEV1 is the volume of air that can forcibly be blown out in one second, after full inspiration. ppFEV1 (predicted for age, gender, and height) is calculated using the Hankinson method.
Baseline, week 4 and 8 assessments

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The relative change from study baseline within the active treatment group in ppFEV1 values
Time Frame: Baseline, week 4 and 8 assessments
Forced Expiratory Volume relative measurements comparing baseline to after 4 and 8 weeks of N91115 treatment. FEV1 is the volume of air that can forcibly be blown out in one second, after full inspiration. ppFEV1 (predicted for age, gender, and height) is calculated using the Hankinson method.
Baseline, week 4 and 8 assessments
