The MeRes100™ BRS (Meril Life Sciences Pvt. Ltd., India) is a novel thin-strut second-generation sirolimus-eluting poly-L-lactic acid (PLLA)-based bioresorbable coronary scaffold is indicated for improving coronary luminal diameter in patients with symptomatic ischemic heart disease due to de novo lesion in native coronary arteries in patients eligible for percutaneous transluminal coronary angioplasty and scaffolding procedures.

After informed consent provided by the subject and confirmation of eligibility criteria and diagnostic angiography, subject will be randomized (2:1) to MeRes100 BRS or Contemporary DES using centralized web-based system.

Subject's Clinical/Telephonic Follow-up will be taken at [Time Frame: 30 days (± 7 days) clinical follow-up, 6 month (± 28 days) clinical follow-up, 1 year (± 28 days) clinical follow-up, 2 years (± 28 days) telephonic follow-up, 3 years (± 28 days) clinical follow-up, 4 years (± 28 days) telephonic follow-up and 5 years (± 28 days) clinical follow-up]

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MeRes 100 Sirolimus-eluting Bioresorbable Vascular Scaffold System (BRS)Device

    Also called XIENCE family Everolimus-eluting Coronary Stent System (EES), Resolute Zotarolimus-eluting Coronary Stent System (ZES), Synergy EES, BioMime/Metafor/Proficient family Sirolimus-eluting Coronary Stent System (SES)

    The MeRes100™ BRS (Meril Life Sciences Pvt. Ltd., India) is a novel thin-strut second-generation sirolimus-eluting poly-L-lactic acid (PLLA)-based bioresorbable coronary scaffold. The first-in-human MeRes-1 trial demonstrated the safety and effectiveness of MeRes100 BRS in the treatment of de novo coronary lesions with lower major adverse cardiac events (MACE) rate (0.93%) and notably, the absence of scaffold thrombosis at one-year follow-up. MeRes100 sirolimus-eluting bioresorbable vascular scaffold system is expected to bioresorb in the artery, approximately over a period of three years and thus, preventing chance of late clinical events like late scaffold thrombosis rates. The imaging analysis has shown that in-segment late lumen loss and in-scaffold late lumen loss (LLL) did not change significantly at two years follow-up as compared to six months data.

Questions about this trial

What is this clinical trial studying?

A study testing MeRes 100 Sirolimus-eluting Bioresorbable Vascular Scaffold System (BRS) in people with Coronary Artery Disease, run by Meril Life Sciences Pvt. Ltd..

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 0 inclusion and 38 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: withdrawn, as of the sponsor's last update on 17 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

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.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Target Lesion Failure (TLF) (time frame: 1 year). 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 17 Apr 2026.
