In this powerpoint, Creative Biolabs will describe basic knowledge of Antibody-Drug Conjugates (ADC), which includes in definition and mechanism of ADC, and its features and future development direction. We hope this video can help you understand what is ADC and what its application. If you have any question, welcome to cantact us at info@creative-biolabs.com.

1. Basic knowledge of

2. Where is the story begin?
Cancer treatment
Surgical resection
Chemotherapy
Radiotherapy
Immunotherapy
Monoclonal
Antibody
Deliver cytotoxic
chemical drug with
tumor cell specificity
Antibody-Drug
Conjugates
mAb: High-specificity and anti-tumor activity but not sufficiently cytotoxicity
Chemical Drug: Potent cell killing activity but too toxic to be used on their own
mAb + Chemical Drug = Antibody Drug Conjugates

3. ADCs are new class of highly potent
biopharmaceutical drug composed of an
antibody linked via a chemical linker to a
biologically active drug or cytotoxic
compound.
 A highly selective monoclonal antibody
 A linker
 A potent cytotoxic agent
What are Antibody Drug Conjugates (ADC)？

4. 1. ADC binding to cell surface antigen;
2. ADC internalization;
3. Transport into lysosome;
4. Degradation in lysosome;
5. Drug release and activation;
6. Cytotoxicity effect
The Mechanism of Action of Antibody Drug Conjugates (ADC)

5. High tumor cell
selectivity
Low immunogenicity
Appropriate stability
Effective cytotoxicity
Homogeneous
Controllable release
The key features of Antibody Drug Conjugates (ADC)

6. Tumor type & Antigen expression Impact of Ig format

• Most commonly used
• Inherent effector function
• Also used but lack of
