LANDMARK Trial: a Randomised Controlled Trial of Myval THV (LANDMARK)
A Prospective, Multinational, Multicentre, Open-label, Randomised, Non-inferiority Trial to Compare Safety and Effectiveness of Meril's Myval Transcatheter Heart Valve (THV) Series vs. Contemporary Valves (Edwards's Sapien THV Series and Medtronic's Evolut THV Series) in Patients With Severe Symptomatic Native Aortic Valve Stenosis
The primary objective of this study (LANDMARK) is to compare the safety and effectiveness of the Myval THV Series with Contemporary Valves (Sapien THV Series and Evolut THV Series) in patients with severe symptomatic native aortic valve stenosis.
This study will be done in total 768 subjects (384:384, Myval THV Series vs. Contemporary Valves)
The randomisation will be carried out with an allocation ratio of 1:1 between Myval THV Series vs. Contemporary Valves (Sapien THV Series and Evolut THV Series)

Detailed Description
LANDMARK Trial is a prospective, randomised, multinational, multicentric, open-label non-inferiority trial of total 768 subjects (384:384, Myval THV Series vs. Contemporary Valves) with severe symptomatic native aortic valve stenosis via transfemoral approach.
- Device sizes applicable for the Myval THV Series: 20 mm, 21.5 mm, 23 mm, 24.5 mm, 26 mm, 27.5 mm, and 29 mm diameter.
- Device sizes applicable for the Sapien 3 THV Series: 20 mm, 23 mm, 26 mm, and 29 mm diameter.
- Device sizes applicable for the Evolut THV Series: 23 mm, 26 mm, 29 mm, and 34 mm diameter.
A non-randomised nested registry will be conducted to include patients requiring extra-large size of Myval THV series (XL Nested Registry)
- Device sizes applicable for the XL Nested Registry: 30.5 mm and 32 mm.
A non-randomized registry will include patients implanted with the Myval THV Series (Lead-in Set).
- The investigators have to perform a minimum of 2 lead-in cases (non-randomised) under the guidance of the lead-in evaluation committee.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
|---|---|
|
Experimental: Myval THV Series
Myval THV Series will include Myval/Myval Inception THVs or any subsequent advanced version commercially available at the study site. This treatment arm will be assigned to 384 / 768 subjects enrolled in a study. |
The devices in the study are intended to improve aortic valve function for patients with severe symptomatic native aortic valve stenosis who are eligible for TAVR therapy.
Every patient must be deemed treatable with an available size of both the test and contemporary heart valves approved for use and commercially available at the investigational centre where the implant procedure is being performed.
Other Names:
|
|
Active Comparator: Contemporary Valves
This treatment arm will be assigned to 384 / 768 subjects enrolled in a study. |
The devices in the study are intended to improve aortic valve function for patients with severe symptomatic native aortic valve stenosis who are eligible for TAVR therapy.
Every patient must be deemed treatable with an available size of both the test and contemporary heart valves approved for use and commercially available at the investigational centre where the implant procedure is being performed.
Other Names:
|
|
Experimental: Myval THV Series XL Nested Registry
A non-randomised, nested registry of patients with anatomy of native aortic annulus suitable to be implanted with extra-large size of Myval THV series (30.5mm or 32mm) as per Heart Team assessment/Investigator's discretion is designed.
The objective of this registry is to assess the safety and effectiveness of extra-large sizes of Myval THV series.
Approximately 100 patients will be recruited from approximately 30 participating centres in LANDMARK Trial

Other Names:
|
|
Experimental: Myval THV Series Lead-in Set
The Lead-in Set aims to ensure investigators adhere to protocol requirements related to the Myval THV Series device, including imaging and procedural guidelines.
Investigators should be independent before enrolling study subjects, allowing for valuable feedback for initial safety assessments.
Each investigator must conduct at least two non-randomized lead-in cases under the guidance of an evaluation committee.
Lead-in subjects will only receive the study device, and if implantation fails, standard care will be provided.
These subjects will not be included in primary or secondary endpoint analyses but will undergo descriptive analysis.
Unique numbers will be assigned to all lead-in subjects, and the committee will evaluate outcomes and site independence for future trial recruitment.
