Inclusion criteria
. Male or female patients at least 18 years of age;
. Electrographically documented history of PSVT (e.g., diagnosis based on ECG , Holter monitoring, etc.). If patient had a prior ablation for PSVT, patient must have documented ECG evidence of PSVT post-ablation;
. History of sustained episodes of PSVT (i.e., typically lasting 20 minutes or longer);
. Females of childbearing potential who are sexually active with a male partner who is not surgically sterile (i.e., vasectomy) must agree to use an approved highly effective form of contraception from the time of signed informed consent until 30 days after the last administration of study drug.;
. Documented hysterectomy;
. Documented bilateral salpingectomy or tubal ligation; or
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Time to an adjudicated termination of a positively adjudicated episode of PSVT and conversion to sinus rhythm (SR) for at least 30 seconds within 30 minutes of start of study drug dosing
Timeframe: Within 30 minutes of start of study drug dosing.
. Systolic blood pressure (SBP) \<90 mmHg after a 5-minute rest in sitting position at the Screening Visit or before the test dose. In patients treated with a chronic prophylactic drug for PSVT (e.g., beta blockers, verapamil, and diltiazem), the drug may be stopped for at least the equivalent of 5 half-lives, patients may be rescreened once, and chronic use of the drug cannot be restarted after randomization;
. History of severe symptoms of hypotension, especially syncope, during episodes of PSVT;
. History of atrial arrhythmia that does not involve the atrioventricular (AV) node as part of the tachycardia circuit (e.g., atrial fibrillation, atrial flutter, intra-atrial tachycardia);
. History of allergic reaction to verapamil;
. Current therapy with digoxin or any Class I or III antiarrhythmic drug, except if these drugs are stopped at least the equivalent of 5 half-lives before the Test Dose Randomization Visit;
. Current chronic therapy with oral amiodarone, or have taken oral amiodarone within 30 days prior to the Test Dose Randomization Visit;
. Evidence of ventricular pre-excitation (e.g., delta waves, short PR interval \<100 msec, Wolff Parkinson White syndrome) on the ECG performed at the Screening Visit or before the test dose administration;
. Evidence of a second- or third-degree AV block on the ECG performed at the Screening Visit or before the test dose administration;
