About this study

Official title: A Multi-center, Randomized, Double-blind, Parallel, Phase 2 Clinical Trial to Compare and Evaluate the Efficacy and Safety of SPC1001 and Monotherapy in Patients With Essential Hypertension

This study purpose is to determine the appropriate combination drug dose by comparing safety and efficacy with placebo, candesartan, and amlodipine monotherapy after 8 weeks of administration of SPC1001 to patients with essential hypertension.

Read the detailed description

This clinical trial is a randomized, double-blind, parallel design, placebo and active drug comparison, and multicenter clinical trial to evaluate the safety and efficacy of investigational drugs after 8 weeks of administration.

Subjects who meet the selection and exclusion criteria should take a placebo for 2 weeks during the run-in period and run a lifestyle improvement program in parallel.

However, if you are already taking antihypertensive drugs at the time of screening, you should stop taking your existing antihypertensive drugs for at least 4 weeks from before the run-in period to the time of randomization to avoid affecting the clinical trial results.

Subjects who meet the final selection and exclusion criteria at the end of the run-in period are randomly assigned 1:1:1:1:1:1:1:1 to each administration group, receive a prescription for clinical trial drugs, and administer for 8 weeks in a double-blind manner.

Encourage the subjects to continuously perform the lifestyle improvement program for 8 weeks during the administration of the clinical investigational drug and visit the testing institution at 4 and 8 weeks during the 8-week trial period, excluding randomized visits, to check the efficacy and safety.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing SPC1001 High, SPC1001 Mid1 and SPC1001 Mid2 in people with Hypertension and Essential Hypertension, run by Shin Poong Pharmaceutical Co. Ltd. at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

MSSBP measures the amount of change after 8 weeks from baseline (time frame: 8 weeks from baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06212648, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Jan 2024.
