Read the detailed description
The study is a multi-center, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of etripamil NS self-administered by patients who experience an episode of PSVT in an at-home setting.
This is an event-driven study. Enrollment into the study will continue until the adjudication of the 180th positively adjudicated PSVT episode in patients treated with double-blind study drug during the Randomized Treatment Period required for the study's pivotal analysis. After the date of the adjudication of the 180th positively adjudicated PSVT episode, all randomized patients will be unblinded at this timepoint and enter into an approximately 6 months open-label period of the study.
- Being tested
- Etripamil NS 70 mg, Placebo

Etripamil NS 70 mg will be administered via the Aptar Pharma Nasal Spray Bidose System, supplied as prefilled devices packaged into child-resistant boxes with instructions for use provided in the study drug box.
PlaceboDrug
Placebo will be administered via the Aptar Pharma Nasal Spray Bidose System, supplied as prefilled devices packaged into child-resistant boxes with instructions for use provided in the study drug box.
| Study group | Role | What they receive |
|---|---|---|
| Etripamil NS 70 mg with Optional Second Dose | Experimental | Dosing regimen that permits a second dose of Etripamil NS 70 mg Receives: Drug: Etripamil NS 70 mg |
| Placebo with Optional Second Dose | Experimental | Dosing regimen that permits a second dose of placebo Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
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
The primary efficacy endpoint is defined as an adjudicated termination of a positively adjudicated episode of PSVT (AV nodal reentrant tachycardia or AV reentrant tachycardia determination if possible) and conversion to sinus rhythm (SR) for at least 30 seconds within 30 minutes of start of study drug dosing.
Measured: Within 30 minutes of start of study drug dosing.
Secondary outcomes (7)
Time to conversion at time points of 5, 10, 15, 45, and 60 minutes
Measured: 1 hour after administration of study drug
Time to conversion in patients with the option of repeat administration
Measured: 1 hour after administration of study drug
The percentage of patients requiring additional medical intervention in emergency department to terminate an episode of PSVT
Measured: Up to 2 years
Number of participants with relief of specific symptoms (i.e., heart palpitations, rapid pulse feeling, chest pain, anxiety, shortness of breath, dizziness, and fainting)
Measured: 1 hour after administration of study drug
Rating of Treatment Satisfaction Questionnaire for Medication (TSQM).
Treatment satisfaction will be analyzed by comparing the Treatment Satisfaction Questionnaire for Medication 9(TSQM-9) score for satisfaction in the 2 treatment groups. The TSQM-9 is composed of 9 questions with responses on a scale of 1 (extremely dissatisfied) to 7 (extremely satisfied). A higher score indicated greater satisfaction with medication.
Measured: 1 hour after administration of study drug
The percentage of adverse event
Measured: Up to 2 years
Number of participants with arrhythmias and conduction disorders detected on surface electrocardiogram（ECG） or cardiac monitoring system (CMS) recordings.
Measured: Up to 2 years

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Etripamil NS 70 mg in people with Tachycardia, Supraventricular and Paroxysmal Supraventricular Tachycardia, run by Corxel Pharmaceuticals at 53 sites in China.
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 12 inclusion and 20 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 2 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 53 sites in China. 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. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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?
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 (time frame: Within 30 minutes of start of study drug dosing.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 2 Nov 2026; AzTrials last refreshed its copy on 7 Nov 2026.
