Objectives

  • Define biologic
  • Outline the approval process for biologics
  • Distinguish the different product categories CBER has regulatory authority
  • Differentiate between a drug, biologic, generic drug, reference product, and biosimilar
  • 7.1: Introduction to Biologics
    Biologics are revolutionizing the biotechnology and health sector – and the most important biotechnology products of this century. Biologics include vaccines, tissue transplants, gene therapy, & stem cell treatment and may include biological molecules such as proteins, and nucleic acids, living tissues, and cells. Some biologics treat a disease or disorder, and some diagnose or prevent them.
  • 7.2: The Center for Biologics, Evaluation, and Research
    The Center for Biologics, Evaluation & Research (CBER) is the primary Center in the FDA, which oversees the regulation of biologic & related products. We will explore in this chapter the broad range of biological products CBER reviews. There are three main review offices in CBER; Office of Blood Research and Review (OBRR); Office of Cellular, Tissue and Gene Therapies (OCTGT); and the Office of Vaccine Research and Review (OVRR).
  • 7.3: Processes for Drug Approval
    The FDA regulates clinical studies in the US, and unapproved drugs and biologics must be conducted under an Investigational New Drug Application (IND). The IND is continually updated with new protocols, study data, and annual reports. The IND for a biologic must contain administrative information, preclinical research results, any previous human experience with the drug, and the clinical protocol. The IND is never approved; rather, it is pending, active, on hold, or partial hold.
  • 7.4: Office of Compliance & Biologics Quality (OCBQ)
  • 7.5: Labeling
    Labeling here is referring to the display of written or printed material on the container or an enclosed document. Labeling includes both FDA approved labelings such as container labels, professional labeling in the package insert (PI – prescribing information), patient labeling (PPI – patient package inserts), medication guides, and instructions for use. But also, any promotional material.

Abstract

Synthetic biology is an emerging technology with potential benefits to various fields, yet also contains potential risks to human and environmental health. The field remains in an emerging state with limited quantitative guidance and a small but growing population of international researchers that conduct work within this field. Given the uncertain nature of this technology, an adaptive and anticipatory governance framework may be necessary to balance the potential benefits that may accrue from the technology's continued research alongside a desire to reduce or eliminate potential risks that may arise. However, such developments must account for the unique political and institutional factors that form a government's risk culture - something that can facilitate or impede the development of adaptive synthetic biology governance moving forward. The TAPIC framework helps illustrate those factors that are essential to develop good governance for emerging technologies like synthetic biology. Specifically, an application of TAPIC to synthetic biology governance indicates that the factors of accountability, participation, and integrity must be bolstered to improve technology governance in governments like with the United States, European Union, and Singapore.


Conclusion

Although CD20 is considered to be an ideal therapeutic target and rituximab-based immunotherapy has become a standard of care for a majority of B-cell malignancies, it is still unclear what all the functions of CD20 are, and how its expression is regulated. The main reason is the large heterogeneity of patients with B-cell malignancies and the lack of mouse models with an evident phenotype which makes CD20 analysis in vivo more difficult. A full understanding of the complexity of regulation of CD20, its physiological function and the exact mechanism of action of anti-CD20 monoclonal antibodies is of pivotal importance to develop new modified anti-CD20 monoclonal antibodies and their therapeutic combination that would yield better clinical efficacy and/or less toxicity. Recently, the possible role of CD20 in microenvironmental interactions was underscored by the observation that CD20 is upregulated in the context of immune niches. This is likely to be of physiological importance, especially for BCR signaling however, it is unclear if this is related to the putative function of CD20 as a regulator of calcium flux triggered by BCR or any potential role in T-cell interactions or some additional function(s). Further investigation of the physiological function of CD20 is required, including the identification of molecules that interact with CD20, since this has implications for the development of rational therapeutic combinations and strategies.

How You Will Learn

Undergraduate students in the program choose courses from among a wide range of research fields to both develop a solid foundation in biology and to build meaningful depth of study in areas of personal interest. In addition to formal lecture and lab courses, students have many opportunities for independent study through seminar courses and research with our outstanding faculty.

Graduate students can choose an MS or PhD program. Both programs stress the importance of the research experience and its value to critical thinking. Students choose from three research tracks, each with course requirements that aim to build depth of study in specific focal areas: Cellular and Molecular Biology, Ecology and Evolution, and Neurobiology.


The Department of Biological Regulation is comprised of approximately 160 people organized in 13 research groups. We are located in the Candiotty and Britannia buildings, which are equipped with all the facilities required for running excellent research.

Congratulations to Dr. Rotem Ben Tov Perry on being promoted to Associate Staff Scientist

Congratulations to Prof. Irit Sagi on being awarded the 2020 ICS-Adama Prize for Technological Innovation- for her pioneering research on enzymatic processes using chemical and biophysical approaches, and for developing inhibitory proteins and antibodies to combat acute and chronic diseases.


The control of glycolysis begins with the first enzyme in the pathway, hexokinase ([link]). This enzyme catalyzes the phosphorylation of glucose, which helps to prepare the compound for cleavage in a later step. The presence of the negatively charged phosphate in the molecule also prevents the sugar from leaving the cell. When hexokinase is inhibited, glucose diffuses out of the cell and does not become a substrate for the respiration pathways in that tissue. The product of the hexokinase reaction is glucose-6-phosphate, which accumulates when a later enzyme, phosphofructokinase, is inhibited.


Phosphofructokinase is the main enzyme controlled in glycolysis. High levels of ATP, citrate, or a lower, more acidic pH decrease the enzyme’s activity. An increase in citrate concentration can occur because of a blockage in the citric acid cycle. Fermentation, with its production of organic acids like lactic acid, frequently accounts for the increased acidity in a cell however, the products of fermentation do not typically accumulate in cells.

The last step in glycolysis is catalyzed by pyruvate kinase. The pyruvate produced can proceed to be catabolized or converted into the amino acid alanine. If no more energy is needed and alanine is in adequate supply, the enzyme is inhibited. The enzyme’s activity is increased when fructose-1,6-bisphosphate levels increase. (Recall that fructose-1,6-bisphosphate is an intermediate in the first half of glycolysis.) The regulation of pyruvate kinase involves phosphorylation by a kinase (pyruvate kinase kinase), resulting in a less-active enzyme. Dephosphorylation by a phosphatase reactivates it. Pyruvate kinase is also regulated by ATP (a negative allosteric effect).

If more energy is needed, more pyruvate will be converted into acetyl CoA through the action of pyruvate dehydrogenase. If either acetyl groups or NADH accumulate, there is less need for the reaction and the rate decreases. Pyruvate dehydrogenase is also regulated by phosphorylation: A kinase phosphorylates it to form an inactive enzyme, and a phosphatase reactivates it. The kinase and the phosphatase are also regulated.


M.A. Biotechnology Program

The Biotechnology MA program trains students in modern aspects of molecular biology with a particular emphasis on approaches used in the biotechnology and pharmaceutical industries. The program provides students with an advanced scientific education and prepares them scientifically for diverse careers in the Biotechnology and Pharmaceutical industries. These careers include:

  • Research science positions in laboratories applying biotechnology to problems in medicine, industry, and agriculture
  • Careers in regulation of drug approval and other biotechnology application
  • Management positions in the biotechnology industry
  • Positions at companies that are investing in biotechnology
  • Working for law firms in biotechnology

The program is intended for students who would like a career in biotechnology without making the 5-7 year commitment to attain a Ph.D. The biotechnology and pharmaceutical industries are among the largest in the U.S. and there is a great demand for professionals with biotechnology expertise.

Thirty (30) points of coursework plus a Master's thesis are required for the MA in Biotechnology. The thesis includes a review of a topic in biotechnology chosen with the help of a program advisor. An intensive laboratory course in Biotechnology is required to give students hands on experience in biotechnology methods. Elective courses (five or more) are selected according to the student’s specific interests. The program can be completed by full-time students in 1 year including the summer semester or at a reduced pace by part-time students.
