Navigating the Complexities of the Regulatory Environment

Our regulatory group for pharmaceutical and medical devices partners with manufacturing quality teams to manage, mitigate, prevent, and resolve regulatory issues, enabling clients to maintain good manufacturing practices (GMP) while realizing gains in operational efficiency.

Our services span the full range of regulatory compliance activities, from FDA compliance audits through larger scope FDA 483 remediation activities. We have assisted manufacturers through FDA responses by providing data reviews and audits, writing investigations, mentoring on investigations, performing root cause analysis, assisting with gap assessments of STP/SOP and validation packages, and reviewing laboratory, manufacturing, and biologic quality control and quality assurance systems.

Industry Experience

Our regulatory team has deep, hands on experience working directly for the FDA and manufacturing companies, providing services that span the end-to-end manufacturing timeline, from pre-submission of pharmaceutical NDA/ANDA and medical device 510(k) applications to manufacturing, packaging and testing.  We also routinely assist quality units in solving and answering technical problems in manufacturing, laboratory and packing, and analysis of the materials supply chain.
