What You Need to Know Before You Apply

What is the purpose of this trial?

This Phase 2 study is a two-stage, serial cohort dose escalation and expansion study of a single 30-minute (IV) infusion of HBI-3000 for the conversion of patients with recent-onset atrial fibrillation (AF).Stage A is open label and all patients will receive HBI-3000. In each of three dose cohorts, up to 10 patients will receive HBI-3000 by IV infusion (30 minutes). Three different dose levels are planned to be administered serially, lowest to highest, with assessment of safety, tolerability, and efficacy prior to proceeding to the next dose level group.Following Stage A, the iDMC will recommend up to two doses of HBI-3000 to be further explored in Stage B. Stage B is a serial, randomized, double-blind and placebo-controlled cohort of two different doses of HBI-3000, with a dose decision after the first cohort. Stage B will be powered to show a difference between HBI-3000 and placebo in conversion rate at each of the two dose levels.

Will I have to stop taking my current medications?

You may need to stop taking certain medications before joining the trial. Specifically, you cannot be on Class I or III antiarrhythmic drugs, metformin, or strong CYP2D6 inhibitors unless they are stopped more than 5 half-lives before enrollment. Also, you should not have taken oral amiodarone in the past 3 months or IV amiodarone within 24 hours before the study drug is given.

Are You a Good Fit for This Trial?

This trial is for adults aged 18-80 with recent-onset atrial fibrillation lasting more than 2 hours but less than 72. Participants must be eligible for cardioversion and on or suitable for anticoagulant therapy. Exclusions include severe heart issues, certain past medical events like stroke, use of specific drugs, ECG abnormalities such as long QT syndrome, and those in other drug/device trials.

Inclusion Criteria

You have had a specific type of irregular heart rhythm for more than 2 hours and less than 72 hours.
I am a candidate for a procedure to correct my heart rhythm.
I am on or can start blood thinner treatment as per heart health guidelines.

Exclusion Criteria

I don't use medications that affect heart rhythm nor have a history of specific heart rhythm disorders.
A blood clot is found in the heart using a special heart imaging test.

What Are the Treatments Tested in This Trial?

Interventions

  • IV HBI-3000
Trial Overview The study tests HBI-3000's ability to convert recent-onset atrial fibrillation to a normal rhythm via IV infusion. Stage A involves escalating doses in cohorts; all receive the drug. Stage B compares two selected doses against placebo in a randomized, double-blind setup to determine efficacy.
