Why DSC Testing is a Critical Step in Developing Biosimilar Drugs
Biologic therapies derived from living organisms have revolutionized the treatment of complex diseases, yet their high development costs are often passed onto patients. Biosimilar drugs offer a promising solution to reduce costs while maintaining therapeutic efficacy. Unlike generic drugs, biosimilars cannot be exact replicas of their reference biologics due to their complex structures, necessitating rigorous testing and regulatory approval.
Unlocking Stability: The Crucial Role of Thermal Analysis in Lyophilization Temperature Optimization
The method of drug delivery significantly influences the final stages of the manufacturing process. Currently, lyophilization—a widely adopted technique—enables drug developers to stabilize formulations and therapeutic molecules using a validated commercial approach. In this process, precise control of pressure and temperature within a lyophilizer facilitates the removal of liquids from formulations containing thermally sensitive or hydrolytically unstable active pharmaceutical ingredients or formulation components.
How to Assess Binding in Drug Discovery
The most popular tool used to characterize binding in the late-discovery phase of drug development is isothermal titration calorimetry (ITC). ITC is a high-resolution method for complete characterization of the basic chemical details of a binding interaction. The calorimeters accomplish this by measuring the heat that is released or absorbed when molecules interact with each other.
BioPharma Drug Development Workflow and Techniques
Drug development is a long and complex process that starts with discovery and, if successful, ends with government approval for marketing. Each step in the drug development process, outlined below, has specific goals with the aim of down-selecting appropriate hits and candidates to an approved drug substance.
マイクロカロリメトリーの歴史
18世紀、多くの科学者が熱の性質について研究を行いました。アイザック・ニュートンは、熱は粒子の振動によって伝達されるものと考え、ロバート・フックは、熱は物体の特性であり、各部位の動きから生じると考えました1 。しかし、熱の測定の歴史に寄与した最初の著名な科学者はスコットランドの物理学者・化学者であるジョン・ブラックでした1 。1761年、彼は正確な測定方法を使って、氷の融点または水の沸点に熱をかけても、温度が変化しないことを発見しました1。 この観察結果により彼は、後の熱力学概念の発端となった、温度と熱とを識別することに成功した最初の科学者となります。
Lithium-ion Battery Quality and Performance Testing with Isothermal Microcalorimetry
Over the past decade, battery research, development, and quality control have adopted in-situ and in-operando isothermal microcalorimetry (IMC) as the leading method to evaluate heat flow during lithium-ion battery cycling. While cycling a cell to failure can take many months, emerging diagnostic tests are able to predict long-term behavior in a matter of weeks.
Evaluating Antibody Stability with Nano Differential Scanning Calorimetry
Antibody stability is crucial for antibody performance in therapeutics. High antibody thermostabilities are essential for creating products with a reasonable shelf life and avoiding problems with deterioration of the biophysical properties of the antibody.
How To Optimize Lyophilization with Thermal Analysis
Lyophilization, also called freeze-drying, is the process of removing water from a sample, often for preservation. Lyophilization involves the sublimation of a sample’s water content, usually through a rapid freezing process. Freezing materials quickly helps avoid the destruction of the cell walls in the sample from the formation of large ice crystals.
How to Improve Gene Therapy Development
Gene therapy is an approach to disease treatment where a patient’s genetic makeup is altered rather than using drugs or surgery. Gene therapy treatment is accomplished through the activation of a particular gene, repairing faulty genes, or introducing new genes to help fight disease.
What is Isothermal Titration Calorimetry (ITC)?
Isothermal Titration Calorimetry (ITC) is an experimental method used to measure the amount of heat released or consumed during a bimolecular chemical reaction. Chemical reactions can be either exothermic or endothermic, depending on the relative energetic stabilities of the reactants. Isothermal titration calorimetry can be used to quantify the magnitude of the heat change during the reaction.
Microcalorimetry for the Biophysical Characterization of Macromolecules
Biological macromolecules are fundamental components of every cell and are therefore essential for all life. These vital molecules are categorized into four major classes: carbohydrates, lipids, proteins, and nucleic acids. Characterizing biological macromolecules is important for understanding their functions and relationships, which empowers the development of new therapies and treatments. Under this branch of macromolecule research, biotherapeutic drug therapy focuses on macromolecular interactions which can lead to disease and/or cell death.
