Clinical Challenges of PARPi Resistance and Identification of Patients Beyond BRCA1/2 PVs for Treatment May Limit Growth
PARP inhibitors (PARPi) have demonstrated remarkable efficacy in cancer treatment associated with BRCA mutations and other HR deficiencies. BRCA1/2 mutations significantly increase the risk of developing breast cancer (60 to 70%) and ovarian cancer (15 to 40%) in women, making PARPi a significant treatment option for such patients.
Despite their promising activity in patients with HR-tumors, resistance to these therapies may develop over time. This is attributed to various mechanism factors such as reactivation of DNA repair pathways, secondary mutations, and epigenetic regulation of BRCA genes. Changes in tumor biology that bypass or limit PARPi's effectiveness in long-term treatment may also limit efficacy.
Studies have revealed that ovarian cancer has one of the poorest prognoses among all gynecologic malignancies. The most prevalent subtype, i.e., high-grade serous carcinoma, is frequently diagnosed at advanced stages with a reported 5-year survival rate of just 30%.
It creates significant hurdles for healthcare providers, as patients initially respond to PARPi therapies, only to experience relapses over time. Hence, it often complicates treatment regimens and leads to disease progression.
Identifying patients beyond BRCA1/2 pathogenic variants (PVs) who could benefit from PARPi treatment remains a challenge. Historically, PARPi has been the most effective in patients with BRCA1/2 mutations. However, recent evidence shows its effectiveness in other gene mutations such as ATM, PALB2, and RAD51C.
Identifying these patients requires precise and comprehensive biomarker testing to broaden the population eligible for PARPi therapies. Ongoing research into combination therapies to counteract resistance mechanisms and the development of new biomarkers will likely be crucial to boost PARP inhibitor therapies and enhance their effectiveness in cancer treatment.
PARP Inhibitors Propel Developments in Cancer Treatment with Expanding Clinical Applications
Globally, more than 18 Mn cases of cancer are diagnosed every year, with an estimated 9.7 Mn cancer-related deaths recorded as of 2022, placing a huge burden on healthcare systems. In recent years, developments in targeted therapies like PARPi have gained significant momentum.
Several PARP inhibitors have been approved for BRCA-mutated ovarian, breast and pancreatic cancer treatment. More than 300 clinical trials are currently underway to examine the use of PARP inhibitors as an anti-cancer therapy in chemo-resistant germline or somatic BRCA1/2 mutated breast, lung, ovarian, and pancreatic cancers.
PARPi veliparib (ABT-888) is currently undergoing various clinical trials to understand its efficacy in treating patients with High-Grade Glioma (HGG), advanced solid tumors, and HER2-negative metastatic breast cancer. Exploration of new PARP inhibitor’s efficacy and applicability is set to propel demand for novel biomarker assays, opening new avenues for companies to innovate next generation diagnostic platforms.
BRCA 1 and 2 Testing Kits Gain Momentum due to Ability to Detect Patients with Hereditary Cancer Risk
BRCA 1 and 2 testing kits segment is set to account for a PARP inhibitor biomarkers market share of 43.4% in 2025. BRCA mutations are well-known biomarkers for PARP inhibitor therapies. This makes BRCA testing an important diagnostic tool to identify patients with hereditary cancer risk, particularly ovarian and breast cancers. It also offers more personalized treatment.
Compared to other testing kits such as Homologous Recombination Deficiency (HRD) or Homologous Recombination Repair (HRR), BRCA 1 and 2 testing is more widely recognized to be used for patient selection in PARP inhibitor therapies, contributing to its high share. A key challenge of HRD testing kits is their high cost due to the involvement of complex genetic analysis. HRR testing kits, on the other hand, require next-generation sequencing to assess various genes, making these more expensive than single-gene tests.
Strong Clinical Evidence to Accelerate PARP Inhibitor Adoption in Breast Cancer Treatment
The breast cancer segment is anticipated to lead with a share of 46.2% in 2025. This is due to its high prevalence and the strong clinical evidence supporting the use of PARP inhibitors in treating BRCA-mutated breast cancer. As per the International Agency for Research on Cancer (IARC) 2025 report, nearly 2.3 Mn new breast cancer cases were reported in 2022, while 670,000 breast cancer-related deaths occurred globally.
PARP inhibitors like Olaparib have been successfully approved and used for the treatment of breast cancer with BRCA mutation, driving the segment’s growth, while outpacing other cancers like ovarian cancer or other less common indications. The identification of BRCA biomarkers has become a key factor in personalized cancer treatment, enabling more precise targeting and improved outcomes with PARP inhibitors.
Ovarian cancer, on the other hand, is anticipated to see moderate growth through 2032. It is because not all ovarian cancer patients are eligible for this treatment. HRD status and BRCA mutations are the main biomarkers used to assess patient responses.
Only about 20 to 25% of ovarian cancer patients, however, have BRCA1/2 mutations, while another 30 to 40% have tumors that are HRD-positive. This implies that a sizable fraction of patients (30 to 50%) is ineligible for PARP inhibitor therapy, which restricts its application.
Increasing Prevalence of BRCA-related Cancers to Create High Demand in the U.S.
North America is projected to hold 42.7% of the global market share in 2025, driven by rising clinical demand for BRCA1/2 testing and precision oncology solutions. In the U.S., breast and ovarian cancers are among the most prevalent cancers.
Currently, there are more than 4 Mn U.S. women with a history of breast cancer. Nearly 316,950 women are set to be newly diagnosed in 2025 with invasive breast cancer and 59,080 new cases of non-invasive ductal carcinoma in situ (DCIS). Additionally, ovarian cancer is anticipated to account for more than 20,000 new cases in 2025.
High incidence rates of BRCA-related cancers are set to significantly fuel demand for biomarker testing in treatment selection. BRCA mutations are a key biomarker in determining the effectiveness of PARP inhibitors. Growing need for precision oncology solutions targeting specific genetic mutations is projected to spur the U.S. PARP inhibitor biomarkers market.
