Take a closer look at Aclairo’s senior scientific management:

Hilary Sheevers, PhD

President, Senior Consultant

A founding partner of Aclairo, Dr. Sheevers serves as President and a Senior Consultant.  She provides scientific and regulatory advice in toxicology, FDA interactions, due diligence and strategic planning for drug development.  At Aclairo, she designs complete toxicology plans, study monitoring plans and support, regulatory support including data interpretation and presentation, as well as preparation of IND, NDA, CTD, and pre-IND submissions.  Dr. Sheevers is involved in biologic and drug development across all CDER divisions at FDA.

At FDA, Dr. Sheevers served as a primary reviewer and manager.  She built policy expertise at the FDA, and understands the reasoning behind many FDA policies.  She attended industry meetings on an almost daily basis.

FDA Committees, which are responsible for drafting FDA policy, and which Dr. Sheevers served include:

  • Pharmacology/Toxicology Coordinating Committee (PTCC)
  • The Executive and full Carcinogenicity Assessment Committee (ECAC, CAC)
  • Photo-carcinogenicity/Photobiology Working Group
  • Reproductive Toxicity Committee (Co-chair)
  • Pregnancy Labeling Working Group (Co-Chair)
  • Inactive Ingredients Committee
  • Arteritis/Non-Monitorable Toxicities Working Group
  • Thalidomide Working Group
  • Botanicals Committee

Dr. Sheevers works full time from the mountains of Arizona in Prescott.  She enjoys golf and hiking and being in a beautiful environment every day.  She returns to the Washington metro office monthly.  She and her husband, Neil, are supporters and volunteers for the Prescott Coalition for Compassion and Justice, a community-wide response to poverty.

Susan Wilson, DVM, PhD

Vice President, Senior Consultant

Dr. Wilson is a founding partner of Aclairo and serves as Vice President and a Senior Consultant, providing scientific and regulatory advice across drug classes based on over 20 years of drug development experience.  In her role as a consultant, she works with clients to develop and implement full toxicology programs, provide interpretation and assessment of nonclinical study results, develop scientific and regulatory strategies to address nonclinical toxicology issues that may arise during the development process, and prepare regulatory documents including INDs, NDAs, CTDs, IMPDs, and briefing packages for meetings. Additionally, she performs due diligence, interacts with the FDA on behalf of her clients, and participates in expert panels. Dr. Wilson has experience with small molecules across FDA divisions, biologics, drug delivery platforms, excipient qualification, and reformulations.

Prior to her career in consulting, Dr. Wilson was a pharmacology/toxicology reviewer at the FDA and, therefore, has experience on both the regulatory and industry sides of drug development. While at FDA, she served on the Immunotoxicology Working Group (co-chair) and the Reproductive Toxicity Committee, was an instructor in the FDA Staff College Immunotoxicology Course, reviewed grant proposals for the Office of Women’s Health, represented the FDA on the Interagency Coordinating Committee for the Validation of Alternative Methods [ICCVAM] – Ocular Toxicity Working Group as well as the Immunotoxicity Working Group, and participated  in the ILSI Workshop as an FDA representative on the Predictivity of Pharmaceuticals in Humans from Animal Data – Hematology Group.

Dr. Wilson enjoys spending time outdoors on her farm with her horses and playing the piano (admittedly rather poorly). She and her husband, David, support and volunteer at the Goochland Free Clinic and Family Services as well as the Lewis Ginter Botanical Gardens.
