Summary
Novel antiangiogenic agents show promise against solid tumors but face development challenges. New surrogate markers are crucial for assessing these angiogenesis inhibitors
Area of Science:
- Oncology
- Pharmacology
Background:
- Novel antiangiogenic agents are being developed as potentially more effective and less toxic alternatives to traditional cytotoxic chemotherapy for solid tumors.
- Early clinical trials reveal the complexity of targeting angiogenesis, indicating that developing effective antiangiogenic therapies is more challenging than initially anticipated.
Purpose of the Study:
- To review the current clinical data on the development of surrogate markers for angiogenesis inhibitors.
- To highlight the necessity of new methods and markers for evaluating the biological activity of antiangiogenic agents.
Main Methods:
- Review of available clinical data.
- Analysis of studies on angiogenesis inhibitors and their surrogate markers.
Main Results:
- The development of clinically useful antiangiogenic therapy is complex.
- New methods and surrogate markers are essential for successful development.
Conclusions:
- Surrogate markers are crucial for assessing the efficacy and guiding the development of novel antiangiogenic agents.
- Further research into robust surrogate markers is needed to overcome the challenges in antiangiogenic therapy development.

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.

Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
