Medical science liaison

Medical Science Liaison (MSL) is a specific role within the pharmaceutical industry, biotechnology, medical device, Contract Research Organizations (CRO), and other health-care industries. MSLs have advanced scientific training and academic credentials generally consisting of a doctorate degree (Ph.D., PharmD., M.D.) in the life sciences.

Role and Responsibilities

The primary role of the MSL is to establish and maintain peer-peer relationships with leading physicians, referred to as Key Opinion Leaders (KOLs), at major academic institutions and other key healthcare entities. MSLs are scientifically trained professionals who provide scientific and clinical knowledge for the safe and effective use of their company’s products. They also provide answers to medical inquiries from physicians and other healthcare professionals.

MSLs are often involved in the following activities:

• Clinical trial design and identification of investigator initiated trials
• Facilitating the process for providing drug samples
• Providing scientific and educational presentations to healthcare professionals
• Responding to requests for information about their company’s products
• Identifying and recommending sites for company-sponsored trials

History

The MSL role was first established by Upjohn Pharmaceuticals in the 1960s as a response to the need for scientifically trained field staff who could communicate complex scientific information to physicians. The role has evolved over time and is now considered a key part of the medical affairs department within pharmaceutical, biotechnology, medical device, CRO and other healthcare industries.

Training and Qualifications

MSLs are required to have advanced scientific training and academic credentials. This is typically a doctorate degree (Ph.D., PharmD., M.D.) in the life sciences. They should also have a deep understanding of the therapeutic area they work in, including the associated pathologies, treatments, and the competitive landscape.
