Ewan Townsend's practice focusses on the commercial transactions involved in the development, exploitation and commercialization of medicinal products, representing many of the world's most sophisticated biotechnology and pharmaceutical companies. His experience includes structuring, drafting and negotiating licence and collaboration agreements, manufacturing, distribution and supply agreements, material transfer agreements, clinical trial agreements, services agreements, co-promotion/co-development alliances, pharmacovigilance and quality agreements.

Ewan also advises on the regulatory issues that frequently arise in the context of those transactions and throughout the medicinal product life cycle, particularly in relation to marketing authorisations, manufacturing, distribution, advertising, pricing and reimbursement. He is also a member of the firm's cannabis team and advises companies on the licensing regime, import, manufacture, distribution and promotion of cannabis-based medicinal products.

In addition to his work in private practice, Ewan has spent time in-house with GlaxoSmithKline and Gilead in London, and Novartis in Sydney.

Ewan has a degree in natural sciences from Cambridge University, and studied law at a post-graduate level.
