This project is located in the Office of Clinical Pharmacology (OCP), Office of Translational Science (OTS). The FDA's published guidance documents outline general principles regarding how to use clinical pharmacology data to support a demonstration of biosimilarity. The implementation of clinical pharmacology programs for biosimilar development depends on the characteristics of PK (and PD when appropriate). Given the diversity of therapeutic proteins in structural features and in the PK properties, the study design characteristics for the PK (or PK and PD) similarity study are determined on a product-by-product basis. This project aims to ultimately improve the efficiency in regulatory review and enhance consistency across programs by developing recommendations for clinical pharmacology study design delineated by product groups which will be more advantageous when compared to the current product-by-product approach. This research projects will cover a wide range of clinical pharmacology topics, such as the use of PD biomarkers, bioanalytical methods for PD biomarkers, modeling and simulation approaches to inform study design, evaluation of potential efficiency gain using PD biomarkers compared to clinical endpoint studies, and assessment of immunogenicity.  

Under the guidance of the mentor, the participant will gain in-depth knowledge on (1) clinical pharmacology of therapeutic proteins by reviewing the PK characteristics of approved products (CDER BLAs) and PD properties based on treatment responses measured using various biomarkers, (2) regulation and regulatory considerations for biosimilar drug development, (3) current practice of study design for clinical pharmacology studies in biosimilar programs, (4) information needed to support study design, (5) similarities/dis-similarities in PK and PD among protein products, (6) modeling and simulation of PK and PD data, and (7) immunogenicity to protein products.

The Center for Drug Evaluation and Research (CDER) performs an essential public health task by making sure that safe and effective drugs are available to improve the health of people in the United States. As part of the U.S. Food and Drug Administration (FDA), CDER regulates over-the-counter and prescription drugs, including biological therapeutics and generic drugs. This work covers more than just medicines.

This program, administered by ORAU through its contract with the U.S. Department of Energy to manage the Oak Ridge Institute for Science and Education, was established through an interagency agreement between DOE and FDA. The initial appointment is for one year, but may be renewed upon recommendation of FDA contingent on the availability of funds. The participant will receive a monthly stipend commensurate with educational level and experience. Proof of health insurance is required for participation in this program. The appointment is full-time at FDA in the Silver Spring, Maryland, area. Participants do not become employees of FDA, DOE or the program administrator, and there are no employment-related benefits.

Completion of a successful background investigation by the Office of Personnel Management is required for an applicant to be on-boarded at FDA.  OPM can complete a background investigation only for individuals, including non-US Citizens, who have resided in the US for a total of three of the past five years.

FDA Ethics Requirements

If an ORISE Fellow, to include their spouse and minor children, reports what is identified as a Significantly Regulated Organization (SRO) or prohibited investment fund financial interest in any amount, or a relationship with an SRO, except for spousal employment with an SRO, and the individual will not voluntarily divest the financial interest or terminate the relationship, then the individual is not placed at FDA.   For additional requirements, see FDA Ethics for Nonemployee Scientists. 

FDA requires ORISE participants to read and sign their FDA Education and Training Agreement within 30 days of his/her start date, setting forth the conditions and expectations for his/her educational appointment at the agency.  This agreement covers such topics as the following:

  • Non-employee nature of the ORISE appointment;
  • Prohibition on ORISE Fellows performing inherently governmental functions;
  • Obligation of ORISE Fellows to convey all necessary rights to the FDA regarding intellectual property conceived or first reduced to practice during their fellowship;
  • The fact that research materials and laboratory notebooks are the property of the FDA;
  • ORISE fellow’s obligation to protect and not to further disclose or use non-public information.

The qualified candidate should have received a doctoral in one of the relevant fields. Degree must have been received within the past five years.

Eligibility Requirements
  • Degree: Doctoral Degree received within the last 60 month(s).
  • Academic Level(s): Postdoctoral.
  • Discipline(s):
    • Chemistry and Materials Sciences (5 )
    • Computer, Information, and Data Sciences (3 )
    • Engineering (9 )
    • Life Health and Medical Sciences (51 )
    • Mathematics and Statistics (4 )
    • Physics (2 )

I have lived in the United States for at least 36 out of the past 60 months. (36 months do not have to be consecutive.)

I have read the FDA Ethics Requirements.
