Questions & Answers

Q: How long did it take to develop Gleevec, and what were the key steps in its development?

The development of Gleevec took several decades, starting with the identification of the abnormal chromosome in chronic myeloid leukemia (CML) patients in the 1960s. It wasn't until 2001 that Gleevec was approved by the FDA as a treatment for CML, following clinical trials and the understanding of the molecular cause of the disease.

Q: How does the development of Gleevec compare to other targeted cancer therapies?

The development of Gleevec was groundbreaking for cancer research because it was one of the first successful targeted therapies. It demonstrated the effectiveness of targeting a specific molecular abnormality, resulting in a significant improvement in survival rates for CML patients. Other targeted therapies, like Herceptin for breast cancer or BRAF inhibitors for melanoma, have since been developed based on similar principles.

Q: Are there any limitations to targeted cancer therapies like Gleevec?

One limitation of targeted therapies is the emergence of resistance. Over time, cancer cells can develop ways to bypass or counteract the effects of the targeted drug. This can lead to the treatment becoming less effective or completely ineffective. Additionally, targeted therapies are only effective for cancers that have specific molecular abnormalities or targets, and not all cancers have identifiable targets.

Q: What are the key elements of precision medicine in cancer research?

Precision medicine in cancer research involves understanding the specific characteristics of a patient's tumor and tailoring treatment based on those characteristics. This can include genetic profiling, molecular testing, and identifying specific targets for treatment. The goal is to match patients with the right therapy at the right time, improving treatment outcomes and minimizing side effects.

Summary & Key Takeaways

• Breakthroughs take time and require a lengthy process of understanding the disease, finding the right target, and developing effective treatments.

• Breakthroughs in infectious disease research over the last century serve as an example of how advancements can be made by targeting specific treatments, prevention, and modulating the immune system.

• The development of Gleevec, a targeted therapy for chronic myeloid leukemia, led to a significant improvement in survival rates for patients, demonstrating the importance of understanding what drives the growth of cancer and developing specific treatments.

• Precision medicine and personalized cancer therapy are the future of cancer research, with a focus on understanding the genetic drivers of cancer and treating based on individual patients' needs.
