Clinical Trial Summary

This is a multicenter, open-label study in adult patients with PA to evaluate the effectiveness and safety of CIN-107 after up to 12 weeks of treatment (Part 1), and then for eligible, consenting patients follow patients in Part 2 for up to 74 weeks for evidence of long-term safety and tolerability.


Description:

For patients in Part 1 only : The treatment duration for patients who complete all 3 dose levels, and who opt not to continue in the extension part of the study, is 12 weeks. For patients who do not complete up-titration, the treatment duration will include at least 4 weeks of dosing with the final dose level. If down-titration of CIN-107 dose is determined at Visit 6 (Week 9), the total treatment duration may be extended to 13 weeks to allow sufficient time for CIN-107 treatment effect at the final dose to be assessed. If the final dose of CIN-107 is reached before week 8 (Visit 5) and no up-titration occurs at Visit 5, the patients will be encouraged to continue CIN-107 treatment till Visit 7 for a total of 12 weeks of treatment. The patients who opt not to continue to Part 2 will not receive any study drug and will return for their safety follow up visit (Visit 8) in 2 weeks. For patients who opt to continue in the extension part (Part 2) of the study: Patients will continue to receive their dose of baxdrostat and be instructed to measure BP at least once every week prior to dosing with CIN-107 in the morning, during the extension phase. Safety surveillance will be conducted if clinically indicated. Repeat and unscheduled testing for serum potassium may be measured at the investigator's clinical site or at local laboratory for a faster turn-around time to allow clinical assessment. These patients entering part 2 will skip Visit 8 and their next visit will be Visit 9.

Outcome

Type Measure Description Time frame Safety issue
Primary To evaluate the safety and tolerability of CIN-107 Outcome measure is overall safety with is a composite of the following individual parameters (unit of measure in brackets):
Adverse Events [number of events];
ECGs [PR interval (msec), RR interval (msec), or QTcF interval (msec); clinically significant ECG findings that are detected during the study will be reported as adverse events];
Clinical laboratory evaluations including standard safety chemistry panel, hematology, coagulation, and urinalysis [clinically significant abnormal laboratory findings that are detected during the study will be reported as adverse events];
Vital signs [pulse, temperature, heart rate and blood pressure] and physical examination data changes noted as clinically significant abnormalities that arise during the study will be recorded as adverse events
74 Weeks
Primary Change in mean seated systolic blood pressure (SBP) Effectiveness measured by change in mean seated SBP after 12 weeks of treatment in patients with PA after 12 weeks of treatment
Secondary Change in mean diastolic blood pressure (DBP) Comparison of changes in mean SBP after 12 weeks of treatment in patients with PA. after 12 weeks of treatment
Secondary The percentage of patients achieving a seated blood pressure (BP) response <140/90 mmHg The percent of patients who achieved a seated BP response <140/90 mmHg after CIN107 treatment will be evaluated at each dose level at Week 12. at Week 12
Secondary The percentage of patients achieving a seated BP response <130/80 mmHg The percent of patients who achieved a seated BP response <130/80 mmHg after CIN107 treatment will be evaluated at each dose level at Week 12. at Week 12
Secondary The percentage of patients achieving either: - a plasma aldosterone concentration (PAC) < 15 ng/dL and a plasma renin activity (PRA) = 0.5 ng/mL/h; or - an ARR < 15; or - unsuppressed renin activity PRA = 1.0 ng/mL/h after 12 weeks of treatment
