Life Sciences Regulatory
When life sciences organizations need comprehensive, end-to-end regulatory support, they turn to Paul Hastings. With decades of experience at and across from the FDA, DEA, and other federal and state agencies, our Life Sciences Regulatory team provides creative, practical and strategic advice that leverages our deep understanding of the law, the science, the agencies and our clients’ business goals.
We solve critical regulatory issues throughout the entire product life cycle, from the earliest phases of product development through approval and post-approval compliance. We have helped clients obtain product approvals and regulatory exclusivities for drugs and biologics across a range of therapeutic areas, including numerous novel molecules, controlled substances and unconventional data packages. In each instance, our goal is to help companies make the case on the science and clinical data within the framework established by the law, precedent and FDA’s public health mission.
Our clients run from early stage companies still identifying compounds to global corporations with scores of approved products and everyone in between, as well as investors, inventors and research universities. Our lawyers have decades of invaluable experience — at FDA, in private practice and in-house — giving us an informed and current sense of agency views, industry practices and what works.
We are laser-focused on helping our clients operate successfully in a highly regulated environment to achieve their business objectives. We understand the timing and precision imperatives of running a life sciences business and collaborate with a client’s in-house medical, science, commercial, compliance and legal teams, as well as outside consultants.
