Study Summary

This trial tests the safety of a potential new medicine when taken at different doses.

Who is the study for?
This trial is for adults with heart failure who have been on stable heart medication for at least 4 weeks. They should have a left ventricular ejection fraction between 35% and <50%, fall under NYHA HF Class I or II, and not be hospitalized for cardiovascular reasons recently. People can't join if they've had recent COVID-19 vaccination, angina symptoms, severe allergies to the drug's components, other clinical study participation recently, uncontrolled diabetes, certain heart diseases or severe lung problems.Check my eligibility
What is being tested?
The trial is testing mRNA-0184 against a placebo in people with chronic heart failure. It aims to find out how safe it is and how well participants tolerate different doses of this new treatment when given once or multiple times.See study design
What are the potential side effects?
Since the study focuses on safety and tolerability of mRNA-0184 in patients with heart failure, potential side effects are being investigated but are not specified here. Common side effects may include reactions at injection site, flu-like symptoms among others typical for vaccine-related interventions.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What is the current intake threshold for participation in this research?

"For this trial to be successful, 98 individuals that satisfy the inclusion criteria must enroll. Patients can join at locations such as University of Alabama at Birmingham: The Kirklin Clinic in Gainesville, Florida and University of Florida in Jacksonville, Tennessee."

Answered by AI

Has the FDA sanctioned SAD Stage: mRNA-0184?

"Given the limited amount of clinical information available regarding SAD Stage: mRNA-0184, our team has assigned a score of 1 on its safety assessment scale. This is due to it being designated as a Phase I trial which indicates scarce evidence for both safety and efficacy."

Answered by AI

At which facilities is this clinical trial being conducted?

"Currently, 15 medical sites are taking on participants for this trial. These facilities can be located in such cities as Gainesville, Jacksonville and Tullahoma among many others. To reduce commuting time associated with the treatment plan, it is best to select a clinic close by your residence."

Answered by AI

Are there any unfilled slots in this trial available for participants?

"Affirmative. Perusal of the clinicaltrials.gov webpage indicates that this research is currently recruiting participants, having been initially posted on November 18th 2022 and most recently updated on September 29th 2023. 98 people are needed in total to be recruited from 15 different medical centres."
