CARMAT (FR0010907956, ALCAR), designer and developer of the world’s most advanced total artificial heart, aiming to provide a therapeutic alternative for people suffering from advanced biventricular heart failure (the “Company” or “CARMAT”), today announces the completion of enrolment of the 52 patients planned in the EFICAS study, and the approval from the French authorities to perform 21 additional Aeson® implants, while awaiting potential reimbursement of the device in France.
Stéphane Piat, Chief Executive Officer of CARMA, commented: “The very strong momentum in the EFICAS study, which enrolment is now complete, reflects the quality and performance of our Aeson® artificial heart and its ability to address the unmet need expressed by healthcare professionals and patients. I am convinced that this study paves the way for strong sales development in Europe and beyond – particularly once its results will have been published, hopefully as soon as end of 2025.
I am also very pleased that, by approving 21 additional implants, the French authorities enable patients in France to continue benefitting from our therapy beyond the EFICAS study. This is a strong sign of confidence in Aeson® artificial heart.
Given the study design, we anticipate to be in a position to file for Aeson®’s reimbursement in France early next year, which could lead to coverage of our artificial heart by the French Social Security system during 2026.
The EFICAS study is also important given our strategy to access the U.S. market, which we are expecting to achieve in 2028.
I would like to thank all patients and healthcare professionals, as well as our teams for their contribution to this important step in Aeson®’s development.”
Enrolment completed in the EFICAS study
Initiated in November 2022, the EFICAS clinical study is the largest ever one conducted by CARMAT. It involves 52 patients eligible for a heart transplant and is carried out across 10 hospitals in France[1].
The primary endpoint of EFICAS is patient survival at 6 months post-Aeson® implant, without disabling stroke, or a successful heart transplant within that period.
EFICAS is key to support Aeson®’s commercial rollout in Europe[2] (through ‘evidence-based medicine’), and secure its reimbursement in France, and is also expected to contribute to securing the Pre-Market Approval (PMA) in the United States, currently targeted for 2028[3].
Given the 6-month post-implant follow-up of patients, CARMAT expects completing the EFICAS study (primary endpoint) early November 2025, which will be followed by the publication of its results.
Approval obtained from French authorities for 21 additional Aeson® implants – and filing for reimbursement in France planned early 2026
As a reminder, the EFICAS study is partially funded by the French State (€13 million for 52 implants[4]), through the “Forfait Innovation” program.
In order to allow patients in France to continue benefitting from Aeson® artificial heart after the completion of the 52 implants in the EFICAS study, the French authorities[5] have approved 21 additional implants, under financial terms equivalent to those of the ‘Forfait Innovation.
In parallel, CARMAT is taking all necessary steps to be in position to submit a reimbursement application (so-called “LPPR”) for Aeson® at the beginning of 2026, which could allow Aeson® to be covered by the French Social Security system during the same year.
