Developing an oncology portfolio of anticancer drugs: the experience of one pharmaceutical company
1AstraZeneca Pharmaceuticals, Macclesfield, UK. George.Blackledge@astrazeneca.com
Abstract:
For a company or institute that wishes to develop new anti-cancer agents, it is necessary to establish a portfolio of agents to reduce the risk of failure. Success rates for developing new agents are low and therefore different biological effect areas should be explored to ensure that at least one agent targeting cancer or a specific histological sub-type of cancer is effectively developed. This paper describes how one pharmaceutical company has developed a range of different agents with the ultimate aim of developing as many of these as is technically feasible into useful new medicines for the treatment of cancer.
Insights
Developing new anti-cancer agents requires a diverse portfolio to mitigate low success rates. Exploring various biological targets increases the likelihood of creating effective cancer treatments.
Area of Science:
- Oncology
- Pharmaceutical Drug Development
Background:
- Drug development success rates are notably low, necessitating risk mitigation strategies.
- A diverse portfolio of anti-cancer agents is crucial for pharmaceutical companies aiming for successful drug discovery.
- Targeting various biological effect areas and cancer subtypes is essential for effective therapeutic development.
Purpose of the Study:
- To outline a strategy for developing a portfolio of anti-cancer agents.
- To describe a pharmaceutical company's approach to creating a range of cancer-targeting drug candidates.
- To maximize the technical feasibility of developing new anti-cancer medicines.
Main Methods:
- Establishing a diverse portfolio of drug candidates targeting cancer.
- Exploring multiple biological effect areas for potential anti-cancer activity.
- Focusing on developing agents for specific histological subtypes of cancer.
Main Results:
- A range of different anti-cancer agents has been developed by the company.
- The company aims to advance as many feasible agents as possible into new medicines.
- The strategy focuses on reducing the risk of failure in anti-cancer drug development.
Conclusions:
- A portfolio approach is vital for successful anti-cancer agent development.
- Diversification across biological targets and cancer types enhances the probability of therapeutic success.
- The described strategy facilitates the progression of multiple anti-cancer agents towards clinical application.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
