II. Definitions
- Biologic Agents
- Pharmaceutical preparations manufactured within biologic systems (e.g. microorganisms)
- Contrast with classical drugs that are chemically synthesized
- Biosimilars
- Biologic agents that are similar to the original or reference biologic agent, but not exact duplicates
- Manufacturers of Biosimilars are not required to show FDA similar efficacy to reference agents
- Biosimilars tend to cost up to one third less of the original reference agents
- Examples
- Neupogen (filgrastim) has 2 Biosimilars (Nivestym, Zarxio)
- Remicade (Infliximab) has 2 Biosimilars (Inflectra, Renflexis)
- Neulasta (pegfilgrastim) has the biosimilar Fulphila
- Biologic agents that are similar to the original or reference biologic agent, but not exact duplicates
III. Types: Biologic Drug Name Interpretations
- Biologic Agent naming conventions have changed over time
- Transitioning from an older source system naming (e.g. Xi), to a target system naming (e.g. fung)
- Older example: Tras-tu-zu-mab (anti-tumor, humanized mononclonal Antibody)
- Newer example: benra-li-zu-mab (immune-targeted, humanized Monoclonal Antibody)
- Suffix
- Mab: Monoclonal Antibody
- Cept: Protein that mimics an Immunoglobulin
- Pre-Suffix
- U: All human origin
- O: Mouse cell origin
- Zu: Humanized origin
- Xi: Mixed or chimeric (part human and part non-human origin)
- Middle, Bridging Syllable
- T: Tumor target
- So: Bone target
- Ci: Circulation target
- Gro: Growth factor target
- Ba: Bacterial target
- Fu: Fungal target
- Vi: Virus
- Ki: Interleukin target
- Li: Immune target
- Toxa: Toxin target

IV. Types: Monoclonal Antibody
- Identical antibodies that are synthesized by a single immune cell type
- Synthesized in labs to be targeted at disease-specific molecules
V. Adverse Effects
- Most targeted biologic agents (e.g. monoclonal antibodies) have the potential for serious adverse effects
- Adverse effects fall in general patterns, but each agent also may have specific side effects
- Infectious disease
- Live Vaccines are contraindicated
- Decreased cellular Immunity
- Tuberculosis
- Sepsis
- Systemic fungal infection
- Hepatitis B activation
- Progressive Multifocal Leukoencephalopathy or PML (polyoma virus)
- Disseminated Herpes Zoster
- Neurologic syndromes
- Multiple Sclerosis
- Seizures
- Guillain Barre
- Hematologic Effects
- Aplastic Anemia or other Pancytopenia
- Malignancy
- Miscellaneous
- Pneumonitis
- Thyroid disease

| Definition (MSH) | Antibodies produced by a single clone of cells. |
| Definition (NCI) | An antibody produced by a clone or genetically homogenous fast-growing cells i.e., hybridoma. Hybridoma cells are cloned to establish cell lines producing a specific antibody that is chemically and immunologically homogeneous. They are widely used in cancer detection, diagnosis, and treatment. |
| Definition (NCI_NCI-GLOSS) | A type of protein made in the laboratory that can bind to substances in the body, including tumor cells. There are many kinds of monoclonal antibodies. Each monoclonal antibody is made to find one substance. Monoclonal antibodies are being used to treat some types of cancer and are being studied in the treatment of other types. They can be used alone or to carry drugs, toxins, or radioactive materials directly to a tumor. |
