• Assess the pharmacologic, pharmacodynamic and pharmacokinetic similarities and differences among the approved and investigational PARP inhibitors in prostate cancer to better understand the activity and toxicities associated with these agents.
• Understand the rationale for combining PARP inhibitors with androgen receptor pathway inhibitors (ARPIs) for patients with prostate cancer.
• Evaluate published research findings with PARP inhibitors in combination with ARPIs for patients with metastatic castration-resistant prostate cancer, and identify patients for whom these regimens would be appropriate.
• Review clinical trial results leading to the FDA approval of PARP inhibitors as monotherapy and in combination with ARPIs for patients with BRCA1/2-mutated hormone-sensitive metastatic prostate cancer, and discern how to optimally incorporate this strategy into current clinical management algorithms.
• Recognize the potential side effects of PARP inhibitor-based therapy for prostate cancer, and develop strategies to prevent, mitigate and manage toxicities.

TARGET AUDIENCE
This activity is intended for medical oncologists, hematology-oncology fellows and other healthcare providers involved in the treatment of breast cancer.

LEARNING OBJECTIVES

• Review available research findings documenting the correlation between the presence of various biomarkers (eg, PIK3CA/AKT1/PTEN alterations, ESR1 mutations) and response to specific therapies, and develop optimal testing algorithms for patients with HR-positive, HER2-negative metastatic breast cancer (mBC).
• Appreciate the incidence and clinical implications of ESR1 mutations in endocrine-resistant mBC and determine the appropriate timing of and platforms to test for these abnormalities.
• Recognize the frequency of PIK3CA/AKT/PTEN pathway abnormalities in patients with HR-positive mBC, and employ evidence-based approaches designed to document and subsequently target these aberrations in individuals with newly diagnosed and relapsed/refractory disease.
• Interrogate published research findings documenting the efficacy of oral selective estrogen receptor degraders for patients with ER-positive, HER2-negative, ESR1 mutation-positive mBC experiencing disease progression on standard endocrine therapy in combination with a CDK4/6 inhibitor in order to optimally integrate these agents into the care of appropriately selected individuals.
• Review available and emerging research data evaluating the role of serial ESR1 testing using circulating tumor DNA to inform early therapeutic switching in patients with HR-positive mBC receiving CDK4/6 inhibitor-based first-line therapy, and consider the potential role of this novel strategy.

TARGET AUDIENCE
This activity is intended for medical oncologists, hematology-oncology fellows and other healthcare providers involved in the treatment of breast cancer.

LEARNING OBJECTIVES

• Review available research findings documenting the correlation between the presence of various biomarkers (eg, PIK3CA/AKT1/PTEN alterations, ESR1 mutations) and response to specific therapies, and develop optimal testing algorithms for patients with HR-positive, HER2-negative metastatic breast cancer (mBC).
• Appreciate the incidence and clinical implications of ESR1 mutations in endocrine-resistant mBC and determine the appropriate timing of and platforms to test for these abnormalities.
• Recognize the frequency of PIK3CA/AKT/PTEN pathway abnormalities in patients with HR-positive mBC, and employ evidence-based approaches designed to document and subsequently target these aberrations in individuals with newly diagnosed and relapsed/refractory disease.
• Interrogate published research findings documenting the efficacy of oral selective estrogen receptor degraders for patients with ER-positive, HER2-negative, ESR1 mutation-positive mBC experiencing disease progression on standard endocrine therapy in combination with a CDK4/6 inhibitor in order to optimally integrate these agents into the care of appropriately selected individuals.
• Review available and emerging research data evaluating the role of serial ESR1 testing using circulating tumor DNA to inform early therapeutic switching in patients with HR-positive mBC receiving CDK4/6 inhibitor-based first-line therapy, and consider the potential role of this novel strategy.

LEARNING OBJECTIVES

• Appreciate the incidence and clinical implications of ESR1 mutations in endocrine-resistant metastatic breast cancer (mBC), and determine optimal strategies to effectively identify patients harboring these abnormalities.
• Understand the biological rationale for, mechanism of action of and pharmacologic similarities and differences between available and investigational oral selective estrogen receptor degraders (SERDs).
• Interrogate published research documenting the efficacy of oral SERD monotherapy for ER-positive, HER2-negative, ESR1-mutated mBC progressing on standard endocrine therapy in combination with a CDK4/6 inhibitor to optimally integrate these agents into the care of appropriately selected patients.
• Review available research data evaluating the role of serial ESR1 testing using circulating tumor DNA as a means to inform early therapeutic switching for patients with hormone receptor-positive mBC receiving CDK4/6 inhibitor-based first-line therapy, and consider the potential role of this novel strategy in treatment.
• Evaluate available clinical trial data with oral SERDs in combination with other systemic therapies (eg, CDK4/6 inhibitors, mTOR inhibitors), and consider the potential role of these regimens in disease management.
• Appreciate side effects associated with available and investigational oral SERDs, and use this information to develop supportive care plans for patients undergoing treatment with this form of therapy.
• Assess ongoing clinical research studies evaluating novel applications of oral SERDs for ER-positive breast cancer, and counsel patients regarding the potential benefits of trial participation.
