Brief 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.

Detailed 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.

MeasureTime frameDescription
Number of Treatment Emergent Adverse Events74 weeksAn AE is defined as any untoward medical occurrence in a clinical investigation that occurs to a patient administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. Adverse events were collected from the beginning of the study until Week 74. Treatment emergent AEs are defined as AEs that newly occur or worsen in severity during the treatment period.
Change From Baseline in Mean Seated Systolic Blood Pressure (SBP) in Patients With Primary Aldosteronism12 weeksThe mean seated SBP was defined as the average of 3 measurements obtained at the clinical site visit. The change from baseline in mean seated SBP after 12 weeks of treatment with CIN-107 (Part 1) is calculated.

Secondary

MeasureTime frameDescription
Change From Baseline in Mean Diastolic Blood Pressure (DBP) in Patients With Primary Aldosteronism12 weeksThe mean DBP was defined as the average of 3 measurements obtained at the clinical site visit. The change from baseline in mean DBP after 12 weeks of treatment with CIN-107 (Part 1) is calculated.
The Percentage of Patients Achieving a Seated BP Response of <140/90 mmHg12 weeksThe percentage of patients achieving a mean seated SBP \<140 mmHg and a mean DBP of \<90 mmHg after 12 weeks of treatment with CIN-107 (Part 1) is calculated.
The Percentage of Patients Achieving a Seated BP Response of <130/80 mmHg12 weeksThe percentage of patients achieving a mean seated SBP \<130 mmHg and a mean DBP of \<80 mmHg after 12 weeks of treatment with CIN-107 (Part 1) is calculated.
The Percentage of Patients Achieving the Pharmacodynamic Marker Response12 weeksPharmacodynamic marker response is defined as 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
