A GUIDE TO FOLLOW-ON BIOLOGICS AND BIOSIMILARS WITH A FOCUS ON INSULIN.
Summary
Follow-on biologics and biosimilars, especially insulins, offer potential cost savings but present regulatory and patient adherence challenges. Understanding their distinctions from generics is crucial for healthcare providers.
Area of Science:
- Pharmacology and Therapeutics
- Biotechnology and Drug Development
- Regulatory Science
Background:
- Healthcare providers often lack familiarity with follow-on biologics and biosimilars.
- Distinguishing these complex biologic products from standard generics is essential.
Purpose of the Study:
- To review follow-on biologics and biosimilars, focusing on insulins within the U.S. regulatory framework.
- To elucidate the structure, efficacy, cost, switching implications, and legal aspects of these products.
Main Methods:
- Comprehensive literature review on biosimilars and insulin follow-on biologics.
- Analysis of regulatory pathways and definitions, including "highly similar" and "interchangeable" biosimilars.
Main Results:
- Biologics are complex molecules; follow-on versions may have efficacy/safety differences.
- Follow-on biologics are regulated under the Public Health Service Act and Federal Food, Drug, and Cosmetic Act.
- Interchangeable biosimilars are pharmacist-substitutable; switching may impact patient adherence due to device changes.
Conclusions:
- Follow-on biologics, including insulins, face regulatory and acceptance hurdles.
- These products hold significant potential for reducing insulin therapy costs for patients.

01:05Insulin Secretory Vesicles
7.0K
Insulin secretory vesicles release insulin to stimulate blood glucose uptake and regulate carbohydrate metabolism. When the blood glucose levels increase, glucose enters the pancreatic β-islet cells through glucose transporters. Once inside, glucose is metabolized through glycolysis, the citric acid cycle, and the electron transport chain, producing ATP. This increase in ATP concentration closes ATP-sensitive potassium channels, leading to depolarization of the membrane and the opening of...

01:28Insulin: The Receptor and Signaling Pathways
3.5K
Insulin action is mediated through a receptor tyrosine kinase, akin to the IGF-1 receptor. The number of receptors per cell varies significantly, from 40 on erythrocytes to 300,000 on adipocytes and hepatocytes. The insulin receptor consists of linked α/β subunit dimers, forming a heterotetramer glycoprotein with two extracellular α subunits and two β subunits spanning the membrane. The α subunits inhibit the inherent tyrosine kinase activity of the β subunits, but...

01:27Insulin Formulations: Types and Delivery
797
Insulin preparations are categorized by their duration of action into short-acting and long-acting types. Two strategies are used to modify insulin's absorption and pharmacokinetic profile: slowing the absorption post-subcutaneous injection, or altering human insulin's amino acid sequence or protein structure. These changes retain the insulin's ability to bind to the insulin receptor, but alter its behavior in solution or after injection.

02:59Biological Effects of Radiation
18.1K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...
