About us

The firm

Founded by Aude VIDAL and Julie VASSEUR, ELSI Avocats is a Life Sciences firm dedicated to the human and veterinary health industries (pharmaceutical companies, manufacturers of medical devices and in vitro diagnostics, cosmetics, foodstuffs and food supplements, raw materials, distributors, medical biology laboratories, pharmacies, pharmacists' groups and health professionals), covering all health product sectors.

The firm has recognised expertise in both advice and litigation throughout the product life cycle (clinical trials, early access, marketing, promotion, health policy, anti-counterfeiting and transparency, product liability).

Through its experience, ELSI Avocats has developed a solid reputation in crisis and reputational risk management.

Our ASSETS :

Support to national and European health authorities

Capitalising on Aude's experience of more than 10 years within a health authority, ELSI brings a practical and pragmatic approach in assisting its clients with national and European health authorities (ANSM, HAS, Ministries, DGCCRF, CHMP, CMDh and others).
The firm also provides special assistance in the follow-up and administrative consequences of inspections and financial sanction procedures.

Managing commercial disputes and product liability
+

Julie's wealth of national and international experience in the industry and in a French life sciences practice gives ELSI significant expertise in product liability cases (medicines, vaccines, medical devices) and commercial litigation (e.g. free riding, disparagement, deceptive trade practices, advertising violations).
The firm also provides strategic advice in these areas.

Turnkey packages: Consultancy subscription & subcontracting
+

ELSI's desire to simplify the consulting process and the activity of its clients has led it to set up consulting packages and a subcontracting offer dedicated to anti-gift and transparency activities.

Marketing and distribution strategy are at the heart of ELSI's expertise

Combining their views and practices, Aude & Julie provide a strategic and complementary analysis of all issues relating to market access and distribution of health products.

Their desire to adopt an exhaustive, but always pragmatic, approach enables them to be anchored in the sectoral practice of their clients, which is essential for a successful analysis of the problems encountered.

A firm rooted in international and shared expertise

In order to offer a complete expertise to its customers, ELSI relies on its network of European and international colleagues but also on its partners and national technical and regulatory experts.
