A Randomized, Double-Blind, Placebo-Controlled Phase IIa Trial to Evaluate Safety, Pharmacokinetics and Pharmacodynamics of Repeated Subcutaneously Administered RBD4059 in Participants with Stable Coronary Artery Disease
EU CTIS ID: 2023-510370-14-00
What this study is testing
To evaluate the safety of RBD4059 compared to placebo when administered subcutaneously as repeated doses in participants with stable CAD that are under treatment with low dose aspirin (75 mg)
- Therapeutic exploratory (Phase II)
A plain-language read of the study's public EU CTIS listing. The study team confirms the details.
Who can take part
You may be able to join if
- Willing and able to give written informed consent for participation in the trial
- Male or female (post-menopausal) participants ≥50-75 years.
- Patients with stable CAD defined as chronic coronary syndromes according to ESCs guideline on chronic coronary syndromes including the category asymptomatic or symptomatic patients >1 year after initial diagnosis or revascularization
- Ongoing standard treatment with aspirin 75 mg for at least 3 months
- Stable prescription drugs i.e., ongoing since at least 30 days prior to randomization, should continue during the trial.
You likely can't join if
- Presence of any significant arrythmia in opinion of the investigator
- AST, ALP, or GGT > ULN (as per the local laboratory reference range), and considered clinically significant by the Investigator
- Positive hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), hepatitis C virus antibody (HCVAb), HIV antibody (HIVAb) at screening
- Any clinical suspicion on acute coronary syndrome or unstable angina at enrolment according to ESC criteria : (i) rest angina, i.e. pain of characteristic nature and location occurring at rest and for prolonged periods (>20 min); (ii) new-onset angina, i.e. recent (2 months) onset of moderate-to-severe angina (Canadian Cardiovascular Society grade II or III); or (iii) crescendo angina, i.e. previous angina, which progressively increases in severity and intensity, and at a lower threshold, over a short period of time.
- Clinically significant acute illness within 7 days before the first dose of trial drug
- Consume more than 8 (female) or 14 (male) units of alcohol per week (1 standard unit of alcohol contains 14 g of alcohol and corresponds to, e.g., 360 mL of beer, 150 mL of wine, or 45 mL of spirits at 40% alcohol content.) within 6 months before screening or positive screen for alcohol abuse or clinical evidence of other drug abuse within 12 months
