Testing Targeted Therapies in Cancer using Structural DNA Alteration Analysis and Patient-Derived Xenografts
Published on: July 25, 2020
Abstract:
A phase II study of the PARP inhibitor olaparib (AstraZeneca) for cancer patients with inherited BRCA1 and BRCA2 gene mutations confirmed earlier results showing clinical benefit for advanced breast and ovarian cancers, and demonstrated evidence of effectiveness against pancreatic and prostate cancers.
Insights
The PARP inhibitor olaparib shows clinical benefit in patients with BRCA1/2 mutations for advanced breast and ovarian cancers. This phase II study also found effectiveness in pancreatic and prostate cancer patients.
Area of Science:
- Oncology
- Genetics
- Pharmacology
Background:
- Inherited BRCA1 and BRCA2 gene mutations are associated with increased risk for several cancers.
- PARP inhibitors represent a targeted therapy approach for cancers with DNA repair deficiencies.
Purpose of the Study:
- To evaluate the efficacy of the PARP inhibitor olaparib in patients with inherited BRCA1/2 mutations across multiple cancer types.
- To confirm previously observed clinical benefits and explore new indications for olaparib.
Main Methods:
- Phase II clinical study design.
- Recruitment of cancer patients with confirmed BRCA1 and BRCA2 gene mutations.
- Administration of olaparib and assessment of clinical outcomes.
Main Results:
- Confirmed clinical benefit of olaparib in advanced breast and ovarian cancers.
- Demonstrated evidence of effectiveness for olaparib in pancreatic cancer.
- Showcased effectiveness of olaparib in prostate cancer.
Conclusions:
- Olaparib demonstrates a consistent clinical benefit in BRCA1/2 mutated cancers, including breast, ovarian, pancreatic, and prostate cancers.
- Olaparib is an effective targeted therapy option for a broader range of cancers with inherited BRCA mutations.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
