Insights

Antibody-drug conjugates (ADCs) are revolutionizing cancer therapy, particularly for breast cancer. Ongoing research explores novel ADCs with innovative designs and targets to improve efficacy and reduce toxicity for better patient outcomes.

Area of Science:

  • Oncology
  • Pharmacology
  • Biotechnology

Background:

  • Antibody-drug conjugates (ADCs) have significantly advanced cancer treatment, with approved agents for breast cancer subtypes targeting HER2 and TROP2.
  • The efficacy and safety of ADCs are determined by their antibody, linker, and payload components, which can be modified to alter clinical profiles.

Purpose of the Study:

  • To review the evolving landscape of novel antibody-drug conjugates (ADCs) in cancer therapy.
  • To highlight emerging opportunities and challenges in the development of next-generation ADCs.

Main Methods:

  • Literature review of current and investigational antibody-drug conjugates.
  • Analysis of ADC components and novel construct designs.

Main Results:

  • Established ADCs targeting HER2 and TROP2 have transformed breast cancer treatment.
  • Numerous novel ADC strategies are under investigation, including targeting new antigens and employing innovative designs like bispecific ADCs, dual payloads, and immune-modulating constructs.

Conclusions:

  • The field of ADCs is rapidly advancing, offering promising new therapeutic avenues for various malignancies.
  • Continued innovation in ADC design and targeting holds significant potential for improving cancer treatment outcomes.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Hybridoma Technology01:31

Hybridoma Technology

Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.

Cancer Vaccines01:30

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
