- Hypersensitivity to the components of apabetalone or any excipient of their formulations.
- Forbidden concomitant therapy:
- Any investigational drug other than the study treatment.
- Based on in vitro data and clinical exposure data, apabetalone is considered unlikely to cause clinically significant drug interactions through inhibition or induction of cytochrome P450 enzyme activity. Nonetheless, as the contribution of metabolic clearance to total drug clearance in man is unknown, potent inhibitors (ketoconazole, itraconazole, ritonavir, indinavir, saquinavir, telithromycin, clarithromycin and nelfanavir) or inducers (Phenytoin, rifampicin, carbamazepine and phenobarbitone, nevirapine, modafinil and St John's Wort) of CYP3A4 must not be used during this study for any patient receiving apabetalone to ensure patient safety. Moreover, bosentan has been associated with a 5-10% risk or reversible raised in LFTs. Although there is no evidence of increased risk of apabetalone-related increases in LFTs amongst bosentan users, the use of bosentan will be forbidden during this study.

About this study
The main OBJECTIVE of this proposal is to extend the investigator's preclinical findings on the role of epigenetics and DNA damage and Bromodomain-Containing Protein 4 (BRD4) inhibition as a therapy for a devastating disease, pulmonary arterial hypertension (PAH).
There is strong evidence that BRD4 plays a key role in the pathological phenotype in PAH accounting for disease progression and that BRD4 inhibition can reverse PAH in several animal models. Intriguingly, coronary artery disease (CAD) and metabolic syndrome are more prevalent in PAH compared with the global population, suggesting a link between these diseases. Interestingly, BRD4 is also a trigger for calcification and remodeling processes and regulates transcription of lipoprotein and inflammatory factors, all of which are important in PAH and CAD. Apabetalone, an orally available BRD4 inhibitor, is now in a clinical development stage with a good safety profile.
At this stage, the investigators propose a pilot study to assess the feasibility of a Phase 2 clinical trial assessing apabetalone in the PAH population. The overall HYPOTHESIS is that BRD4 inhibition with apabetalone is a safe and effective therapy for PAH.
Read the detailed description
In line with most pilot and safety studies, this is a two-centre (Quebec and Calgary) open-label trial. A 4-week pre-treatment phase will allow ensuring that patients are on stable doses of medication. Patients will be given doses of apabetalone 100mg BID for 16 weeks. Patients will be regularly followed. At baseline and week 16, a cardiac catheterization and MRI will assess changes in pulmonary hemodynamics and RV function.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Apabetalone in people with Pulmonary Arterial Hypertension, run by Steeve Provencher at 2 sites in Canada.
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 10 inclusion and 34 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 25 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Canada. 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?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
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?
Change in Pulmonary Vascular Resistance (PVR), dyn·s·cm-5 (time frame: Baseline,and 16 weeks later). 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 NCT03655704, which also lists 82 linked publications.
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 25 Apr 2022.
