Safety of Ataciguat in Patients With Moderate Calcific Aortic Valve Stenosis
A Phase 1 study testing Ataciguat in people with Aortic Valve Stenosis, run by Jordan D. Miller, Ph.D. at 1 site in United States.
Trial summary
This study will determine whether Ataciguat (HMR1766) is well-tolerated in patients with mild to moderate calcific aortic valve stenosis. The primary focus of these studies will be on changes in blood pressure and orthostatic tolerance (i.e., ability to stand up without passing out), and determining whether treatment… Read more about this study

About this study
Official title: A Phase Ib Randomized, Placebo-controlled, Double-blinded Study Evaluating the Safety of Ataciguat (HMR1766) in Patients With Moderate Calcific Aortic Valve Stenosis
This study will determine whether Ataciguat (HMR1766) is well-tolerated in patients with mild to moderate calcific aortic valve stenosis. The primary focus of these studies will be on changes in blood pressure and orthostatic tolerance (i.e., ability to stand up without passing out), and determining whether treatment with Ataciguat results in significant reductions in blood pressure in this patient population.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
AtaciguatDrug
Also called HMR1766
PlaceboDrug
Also called Placebo gel capsule of identical composition to Active group, but does not have active compound.
| Study group | Role | What they receive |
|---|---|---|
| Placebo | Placebo comparator | Placebo gel capsule, dosage matches number of Ataciguat capsules for each respective dose, capsules taken once daily with breakfast for 14 consecutive days. Receives: Drug: Placebo |
| Ataciguat | Active comparator | Ataciguat, orally administered gel capsule, 50, 100, or 200 mg, once per day with breakfast for 14 consecutive days Receives: Drug: Ataciguat |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of patients experiencing orthostatic hypotension
The primary objective of the current study is to determine whether Ataciguat (HMR1766) is well-tolerated by patients with moderate calcific aortic valve stenosis. In this particular patient population, incidence of orthostatic intolerance/symptomatic hypotension is a potential concern.
Measured: Baseline - 14 days
The change in blood pressure following the transition from sitting to standing
The primary objective of the current study is to determine whether Ataciguat (HMR1766) is well-tolerated by patients with moderate calcific aortic valve stenosis. In this particular patient population, incidence of orthostatic intolerance/symptomatic hypotension is a potential concern. Transitioning from sitting to standing is a functional test that will allow us to examine the effects of Ataciguat on blood pressure regulation in response to a relevant orthostatic stress.
Measured: Baseline - 14 days
The change in blood pressure following progressive head-up tilt
The primary objective of the current study is to determine whether Ataciguat (HMR1766) is well-tolerated by patients with moderate calcific aortic valve stenosis. In this particular patient population, incidence of orthostatic intolerance/symptomatic hypotension is a potential concern. Tilt table testing will allow us to examine the effects of Ataciguat on blood pressure regulation in response to a tightly controlled orthostatic stress.
Measured: Baseline - 14 days
Subject self-reports of light-headedness/orthostatic intolerance during the standing test and the head-up tilt testing

In this particular patient population, incidence of orthostatic intolerance/symptomatic hypotension is a potential concern. Evaluating subject perceptions of light-headedness/orthostatic intolerance will help us to understand the relationship between changes in blood pressure and changes in symptoms in this patient population before and after treatment with Ataciguat.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Ataciguat in people with Aortic Valve Stenosis, run by Jordan D. Miller, Ph.D. 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 14 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 7 Jul 2016. 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?
Number of patients experiencing orthostatic hypotension (time frame: Baseline - 14 days). The study lists 4 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 NCT02049203, 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 7 Jul 2016.
