About this study

Official title: A Randomized Double-blind, Placebo-controlled, Non-confirmatory Study to Assess Safety, Tolerability, PK, and PD of Single Ascending and Multiple Doses of ISIS 681257 in Healthy Japanese Participants

The purpose of the study is to assess the safety, tolerability, and pharmacokinetics (PK) of single and multiple subcutaneous (SC) doses of Pelacarsen (ISIS 681257) in healthy Japanese participants.

Read the detailed description

This was a randomized, placebo-controlled, participant and investigator-blinded, single ascending and multiple-dose study of Pelacrsen (ISIS 681257) in up to 29 healthy Japanese male and female participants. The study was conducted in two parts:1) Single ascending dose (SAD) including up to a 28-day screening period, a baseline period, dose with study drug on Day 1, a 2-day (48 hours) post-dose in-patient observation period, followed by an out-patient observation period up to Day 90; 2) Multiple doses (MD) including up to a 28-day screening period, a baseline period, dose with study drug up to Day 85, a 2-day (48 hours) post-dose in-patient observation period, followed by an out-patient observation period up to Day 204.

In the SAD period, participants were randomized to receive single dose of Pelacarsen or placebo.

Upon completion of the SAD period participants were randomized to receive multiple doses of Pelacarsen.

Being tested
Placebo, Pelacarsen

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Pelacarsen in people with Healthy Participants, run by Ionis Pharmaceuticals, Inc. at 1 site in United States.

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 5 inclusion and 7 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 20 Apr 2022. 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 United States. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

SAD: Percentage of Participants With Clinically Significant Changes From Baseline in Clinical Laboratory Evaluation Parameters (time frame: Up to Day 90). The study lists 6 primary outcomes in all. 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 NCT05337878, 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 20 Apr 2022.
