Phase II study of pazopanib with oral topotecan in patients with metastatic and non-resectable soft tissue and bone sarcomas

BACKGROUND: Pazopanib is active in refractory soft-tissue sarcoma (STS) and significantly prolongs PFS. Prior studies of combinations of metronomic topotecan with pazopanib have indicated preclinical evidence of response in patients with sarcoma. METHODS: This prospective, single arm, phase II study evaluated the efficacy of the combination of pazopanib with topotecan in patients with metastatic or unresectable non-adipocytic STS. Furthermore, it incorporated exploratory arms for osteosarcoma and liposarcoma. The primary endpoint was progression-free rate at 12 weeks in the non-adipocytic STS cohort. RESULTS: 57.5% of patients in the non-adipocytic STS cohort were progression free at 12 weeks, which did not meet the primary endpoint of the study (66%). The exploratory osteosarcoma cohort exceeded previously established phase II trial comparator data benchmark of 12% with a PFR at 12 weeks of 69.55%. Treatment with the combination of pazopanib and topotecan was accompanied by a grade 3 or 4 toxicities in most patients. CONCLUSIONS: In this prospective trial in refractory metastatic or unresectable STS and osteosarcoma, the combination of pazopanib with topotecan did not meet its primary endpoint of progression-free rate at 12 weeks. The combination of pazopanib with topotecan was associated with a high degree of toxicity

Clinical Implications of Circulating Tumor DNA Tumor Mutational Burden (ctDNA TMB) in Non‐Small Cell Lung Cancer

Establishing noninvasive biomarkers for response to immune checkpoint blockade is important. This study explored the use of circulating tumor DNA tumor mutational burden (ctDNA TMB) in non‐small cell lung cancer (NSCLC). This article evaluates this novel biomarker and reports on the landscape and clinical utility of ctDNA TMB in NSCLC

Patient-reported tolerability of veliparib combined with cisplatin and etoposide for treatment of extensive stage small cell lung cancer: Neurotoxicity and adherence data from the ECOG ACRIN cancer research group E2511 phase II randomized trial.

OBJECTIVES: The ECOG-ACRIN Cancer Research Group trial E2511 recently demonstrated a potential benefit for the addition of veliparib to cisplatin-etoposide (CE) in patients with extensive stage small cell lung cancer (ES-SCLC) in a phase II randomized controlled trial. Secondary trial endpoints included comparison of the incidence and severity of neurotoxicity, hypothesized to be lower in the veliparib arm, and tolerability of the addition of veliparib to CE. Physician-rated and patient-reported neurotoxicity was also compared. MATERIALS AND METHODS: Patients randomized to veliparib plus CE (n = 64) or placebo plus CE (n = 64) completed the 11-item Functional Assessment of Cancer Therapy Gynecologic Oncology Group Neurotoxicity (questionnaire pre-treatment, end of cycle 4 [ie 3 months after randomization] and 3 months post-treatment [ie 6-months]). Adherence analysis was based on treatment forms. RESULTS AND CONCLUSION: No significant differences in mean or magnitude of change in neurotoxicity scores were observed between treatment arms at any time point. However, patients in the placebo arm reported worsening neurotoxicity from baseline to 3-months (M difference = -1.5, P = .045), compared to stable neurotoxicity in the veliparib arm (M difference = -0.2, P = .778). Weakness was the most common treatment-emergent (\u3e50%) and moderate to severe (\u3e16%) symptom reported, but did not differ between treatment arms. The proportion of adherence to oral therapy in the overall sample was 75%. Three percent of patients reported clinically significant neurotoxicity that was not captured by physician assessment. Neurotoxicity scores were not different between treatment arms. The addition of veliparib to CE appeared tolerable, though weakness should be monitored. CLINICALTRIALS. GOV IDENTIFIER: NCT01642251

Patient-Reported Outcome Dashboards Within the Electronic Health Record to Support Shared Decision-making: Protocol for Co-design and Clinical Evaluation With Patients With Advanced Cancer and Chronic Kidney Disease

BackgroundPatient-reported outcomes—symptoms, treatment side effects, and health-related quality of life—are important to consider in chronic illness care. The increasing availability of health IT to collect patient-reported outcomes and integrate results within the electronic health record provides an unprecedented opportunity to support patients’ symptom monitoring, shared decision-making, and effective use of the health care system. ObjectiveThe objectives of this study are to co-design a dashboard that displays patient-reported outcomes along with other clinical data (eg, laboratory tests, medications, and appointments) within an electronic health record and conduct a longitudinal demonstration trial to evaluate whether the dashboard is associated with improved shared decision-making and disease management outcomes. MethodsCo-design teams comprising study investigators, patients with advanced cancer or chronic kidney disease, their care partners, and their clinicians will collaborate to develop the dashboard. Investigators will work with clinic staff to implement the co-designed dashboard for clinical testing during a demonstration trial. The primary outcome of the demonstration trial is whether the quality of shared decision-making increases from baseline to the 3-month follow-up. Secondary outcomes include longitudinal changes in satisfaction with care, self-efficacy in managing treatments and symptoms, health-related quality of life, and use of costly and potentially avoidable health care services. Implementation outcomes (ie, fidelity, appropriateness, acceptability, feasibility, reach, adoption, and sustainability) during the co-design process and demonstration trial will also be collected and summarized. ResultsThe dashboard co-design process was completed in May 2020, and data collection for the demonstration trial is anticipated to be completed by the end of July 2022. The results will be disseminated in at least one manuscript per study objective. ConclusionsThis protocol combines stakeholder engagement, health care coproduction frameworks, and health IT to develop a clinically feasible model of person-centered care delivery. The results will inform our current understanding of how best to integrate patient-reported outcome measures into clinical workflows to improve outcomes and reduce the burden of chronic disease on patients and health care systems.
