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

LEARNING OBJECTIVES

• Appraise the scientific rationale for and mechanism of action of CD20 x CD3 bispecific antibodies in patients with various forms of non-Hodgkin lymphoma (NHL), and understand the similarities and differences between currently available agents in this class.
• Develop an understanding of the current clinical research database with CD20 x CD3 bispecific antibodies for the management of diffuse large B-cell lymphoma and follicular lymphoma, and optimally integrate these treatments into the care of patients with these diseases.
• Understand the pathophysiology of cytokine release syndrome (CRS) associated with CD20 x CD3 bispecific antibodies employed in the care of NHL, and recognize the frequency, timing and severity of this side effect.
• Evaluate consensus recommendations and expert best practices, and use this information to develop strategies to optimally identify, manage and educate about CRS associated with bispecific antibodies.
• Appreciate the practical administration requirements associated with various CD20 x CD3 bispecific antibodies in order to appropriately educate eligible patients.
• Recognize the spectrum, frequency and severity of other adverse events (eg, neurotoxicity, infections, cytopenias) associated with CD20 x CD3 bispecific antibodies, and consider recommended approaches to prevent, ameliorate and manage these side effects.

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

LEARNING OBJECTIVES

• Describe published research data with immune checkpoint inhibitors alone or in combination with other systemic therapies in the management of metastatic gastric, gastroesophageal junction (GEJ) and esophageal cancers, and optimally integrate these strategies into nonresearch treatment algorithms.
• Assess available data with monoclonal antibody therapy directed at claudin 18.2 (CLDN18.2) in combination with chemotherapy as first-line treatment for HER2-negative, CLDN18.2-positive gastric or GEJ cancer, and optimally incorporate this approach into management algorithms.
• Review published and emerging research findings with HER2-targeted therapies for patients with HER2-positive gastroesophageal cancers, and assess the current and future role of various agents and regimens.
• Appreciate the rationale for, available data with and ongoing research studies evaluating novel targeted and immunotherapeutic strategies for gastroesophageal cancers to enhance clinical trial participation for appropriately identified patients.

Faculty

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

LEARNING OBJECTIVES

• Describe published research data with immune checkpoint inhibitors alone or in combination with other systemic therapies in the management of metastatic gastric, gastroesophageal junction (GEJ) and esophageal cancers, and optimally integrate these strategies into current treatment algorithms.
• Assess available data with approved and investigational Claudin 18.2 (CLDN18.2) monoclonal antibody therapy-based combination approaches as first-line treatment for HER2-negative, CLDN18.2-positive gastric or GEJ cancer, and consider this information for current patient care.
• Review published and emerging research findings with novel HER2-targeted therapeutic approaches for HER2-positive gastroesophageal cancers, and assess their nonresearch role in patient care.
• Evaluate available treatment strategies for patients with gastric cancer and multiple biomarkers, such as HER2, PD-L1and CLDN18.2, and assess for optimal sequencing of available targeted therapies.
• Recall strategies commonly employed to mitigate and manage gastrointestinal side effects of CLDN18.2 monoclonal antibody-targeted therapy, and use this information to appropriately intervene when these side effects are suspected or diagnosed.

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

LEARNING OBJECTIVES

• Describe cereblon’s role in the degradation of key oncogenic proteins in order to better understand the rationale for the development of cereblon E3 ligase modulators (CELMoDs).
• Review the mechanism of action and unique characteristics of the CELMoDs under development for multiple myeloma (MM), and appreciate the similarities and differences between these therapies and currently approved immunomodulatory agents.
• Evaluate published efficacy and safety findings with CELMoDs in the advanced stages of development to prepare for the potential clinical availability of these agents for patients with relapsed/refractory MM.
• Assess various combination strategies under investigation with CELMoDs and other agents commonly administered to patients with MM, and recognize available and emerging research findings with various combination approaches.
• Appreciate the frequency and severity of various therapy-related adverse events encountered by patients undergoing treatment with CELMoDs, and use this knowledge to identify, manage and mitigate resultant side effects.

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

LEARNING OBJECTIVES

• Understand the clinical relevance of circulating tumor DNA (ctDNA) as a prognostic and predictive biomarker in lung cancer, and recognize the rationale for its use in detecting molecular residual disease (MRD) in patients.
• Outline optimal approaches for ctDNA-based assessment of MRD, and determine the appropriate timing and platform for testing ctDNA status in patients with lung cancer.
• Appreciate published datasets documenting the clinical utility of ctDNA testing in risk stratification, surveillance and therapeutic decision-making for patients with lung cancer, and consider the current and potential role of this strategy in personalizing treatment recommendations.
• Recall ongoing efforts evaluating ctDNA-based assays to assist with clinical decision-making in lung cancer, and appropriately refer patients for study participation.

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

LEARNING OBJECTIVES

• Review how biological factors and patient characteristics such as age, performance status, prior treatment, comorbidities and preexisting conditions influence the selection and sequencing of treatment for metastatic urothelial bladder cancer (mUBC).
• Interrogate published efficacy and safety findings with anti-PD-1/PD-L1 antibodies in combination with antibody-drug conjugate (ADC) therapy as first-line treatment for mUBC, and consider the current role of this strategy in patient care.
• Recall pivotal clinical trial findings with ADCs and tyrosine kinase inhibitors for previously treated locally advanced or metastatic UBC, and identify patients for whom these approaches would be appropriate.
• Appreciate the frequency and severity of therapy-related adverse events commonly encountered by patients receiving guideline-endorsed agents and regimens for mUBC, and enact effective monitoring and management procedures.
• Describe the scientific justification for and published research data with novel strategies under investigation for UBC, and effectively prioritize clinical trial opportunities for eligible patients.
