Real-world patterns and sequences of targeted therapy use in chronic lymphocytic leukemia and small lymphocytic lymphoma in the United States: a longitudinal study.

With increasing focus on novel targeted therapies for chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), this longitudinal claims-based study evaluated real-world CLL/SLL treatment sequences, particularly sequential targeted therapy. Among patients with first-line (1 L) treatment in 2014-2017 (N = 2,612; median follow-up = 3 years), the most common 1 L treatment was chemoimmunotherapy (CIT; 44.6%), followed by CD20 (25.2%) and Bruton's tyrosine kinase inhibitors (BTKi; 21.7%). Among those with 1 L in 2018-2021 (N = 4,534; median follow-up = 1 year), these were BTKi (45.5%), CD20 (20.4%), CIT (17.5%), and B-cell lymphoma 2 inhibitor (8.3%). In 2014-2017, the proportion of patients receiving sequential targeted therapy in the first 2 LOTs was 11.2% (80.2% was BTKi→BTKi); in 2018-2021, this proportion was 34.3% (66.4% was BTKi→BTKi). Over time, there was a substantial increase in targeted therapy use in 1 L and sequential targeted therapy, particularly with BTKi→BTKi. Future studies should assess clinical outcomes to determine optimal sequences for CLL/SLL and reasons for restarting BTKi.

Cost-effectiveness of adding quizartinib to induction chemotherapy for patients with FLT3-mutant acute myeloid leukemia.

The FLT3 inhibitor quizartinib has been shown to improve overall survival when added to intensive induction chemotherapy ("7 + 3") in patients 18-75 years old with newly diagnosed AML harboring a FLT3-ITD mutation. However, the health economic implications of this approval are unknown. We evaluated the cost-effectiveness of quizartinib using a partitioned survival analysis model. One-way and probabilistic sensitivity analyses were conducted. In the base case scenario, the addition of quizartinib to 7 + 3 resulted in incremental costs of $289,932 compared with 7 + 3 alone. With an incremental gain of 0.84 quality-adjusted life years (QALYs) with quizartinib + 7 + 3 induction vs. 7 + 3 alone, the incremental cost-effectiveness ratio for the addition of quizartinib to standard 7 + 3 was $344,039/QALY. Only an 87% reduction in the average wholesale price of quizartinib or omitting quizartinib continuation therapy after completion of consolidation therapy and allogeneic hematopoietic cell transplant would make quizartinib a cost-effective option.

Real-World Survival, Healthcare Resource Utilization, and Costs Among U.S. Elderly Patients With Diffuse Large B-Cell Lymphoma (DLBCL) Treated With R-GemOx in the Relapsed/Refractory Setting.

BACKGROUND: Little recent real-world evidence exists on overall survival, healthcare resource utilization (HCRU), and costs among R/R DLBCL patients treated with the combination of rituximab, gemcitabine, and oxaliplatin (R-GemOx), a widely-used regimen for patients ineligible for stem cell transplant due to age or comorbidities. PATIENTS AND METHODS: This retrospective analysis used 2014 to 2019 U.S. Medicare claims. Individuals aged ≥66 years with a new DLBCL diagnosis between October 1, 2015 and December 31, 2018 and continuous fee-for-service Medicare Part A, B, and D coverage in the 12 months pre- and postindex were followed to identify the sample of patients with evidence of R-GemOx treatment in the second-line (2L) or third-line (3L) setting. Outcomes included overall survival, all-cause and DLBCL-related HCRU, and costs after R-GemOx initiation. RESULTS: The final sample included 157 patients who received treatment with R-GemOx in the R/R settings (mean (SD) age 77.5 (6.0) years, 39.5% age>80 years; 66.9% male; 91.1% White). Of these, 126 received R-GemOx in the 2L setting and 31 received R-GemOx in the 3L setting. Median overall survival from R-GemOx initiation was 6.9 months and 6.8 months in the 2L and 3L setting, respectively. Rates of all-cause hospitalization (68.1% [2L] and >90% [3L]) and hospice use (42.9% [2L] and 51.7% [3L]) were high in the 12 months after R-GemOx initiation. All-cause total costs were substantial ($144,653 [2L] and $142,812 [3L]) and approximately 80% of costs were DLBCL-related within 12 months of R-GemOx initiation. CONCLUSION: Elderly U.S. Medicare beneficiaries diagnosed with DLBCL who initiated R-GemOx treatment in the R/R setting have poor overall survival, high rates of HCRU, and substantial costs.

Real-world analysis of adverse event rates after initiation of ibrutinib among Medicare beneficiaries with chronic lymphocytic leukemia.

BACKGROUND: The first-generation BTK inhibitor ibrutinib is a standard-of-care therapy in the treatment of chronic lymphocytic leukemia (CLL) despite potential side effects that often lead to discontinuation. METHODS: This study used 2013-2019 claims data to describe the incidence rate of adverse events (AEs) among elderly Medicare beneficiaries newly initiating ibrutinib for CLL. RESULTS: The final sample contained 11,870 Medicare beneficiaries with CLL (mean age 77.2) newly initiating ibrutinib, of whom 65.2% discontinued over mean follow-up of 2.3 years. The overall incidence rate of AEs was 62.5 per 1000 patient-months for all discontinuers and 32.9 per 1000 patient-months for non-discontinuers. Discontinuers had a higher incidence rate of AEs per 1000 patient-months compared with non-discontinuers for all AEs examined, including infection (22.8 vs. 14.5), atrial fibrillation (15.1 vs. 7.0), anemia (21.9 vs. 14.5), and arthralgia/myalgia (19.5 vs. 13.6). CONCLUSION: In this first real-world study of a national sample of elderly US patients treated with ibrutinib, we found a clear unmet need for improved management of ibrutinib-related AEs and/or new treatments to improve real-world outcomes in patients with CLL.

Real-world treatment patterns, survival, health resource use and costs among Medicare beneficiaries with diffuse large B-cell lymphoma.

Aim: To examine real-world treatment patterns, survival, healthcare resource use and costs in elderly Medicare beneficiaries with diffuse large B-cell lymphoma (DLBCL). Methods: 11,880 Medicare patients aged ≥66 years with DLBCL between 1 October 2015 and 31 December 2018 were followed for ≥12 months after initiating front-line treatment. Results: Two-thirds (61.2%) of the patients received standard-of-care R-CHOP as first-line treatment. Hospitalization was common (57%) in the 12-months after initiation of 1L treatment; the mean DLCBL-related total costs were US$84,416 during the same period. Over a median follow-up of 2.1 years, 17.8% received at least 2L treatment. Overall survival was lower among later lines of treatment (median overall survival from initiation of 1L: not reached; 2L: 19.9 months; 3L: 9.8 months; 4L: 5.5 months). Conclusion: A large unmet need exists for more efficacious and well-tolerated therapies for older adults with DLBCL.

Diffuse large B-cell lymphoma (DLBCL) is the most common form of Non-Hodgkin lymphoma, and it becomes more common with age. While researchers continue to develop newer, more effective treatments for DLBCL, it is important to understand how patients use existing treatments and the associated costs, particularly among the elderly. In our real-world analysis of nearly 12,000 older patients with DLBCL, we found high rates of hospitalization and hospice use, short length of life in later lines of therapy and substantial healthcare costs. Our findings suggest a large current unmet need for more effective and well-tolerated therapies for older adults with DLBCL in both the front-line and relapse/refractory settings.

Ibrutinib discontinuation and associated factors in a real-world national sample of elderly Medicare beneficiaries with chronic lymphocytic leukemia.

Prior studies evaluating ibrutinib discontinuation are limited to clinical trials and selected medical centers and hence may not reflect real-world practice. This study used Medicare claims (2013-2019) to examine ibrutinib discontinuation and associated factors among elderly patients with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL). Over a median follow-up of 2.1 years, two-thirds (65.2%) of the 11,870 new ibrutinib initiators were discontinued, with half (45.1%) of patients discontinuing within 12 months of initiation. Factors such as advanced age, lack of Part D low-income subsidy, evidence of prior CLL/SLL treatment, and cardiovascular comorbidities (e.g. atrial fibrillation) were associated with higher risk of discontinuation. Over a median of 1.2 years from discontinuation, 40% of discontinuers initiated another CLL/SLL treatment after ibrutinib discontinuation; 25% of patients restarted ibrutinib treatment at some point over follow-up. Our findings point to a large unmet need with the widely used BTKi ibrutinib and underscore the importance of ongoing development of efficacious and well-tolerated CLL/SLL therapies.

Peripheral Blasts in a Patient Receiving Chemotherapy.

An older patient with stage II bladder carcinoma presented with 1 week of fatigue and 2 days of dyspnea on exertion. He was receiving carboplatin/gemcitabine with 6 mg of pegylated G-CSF chemotherapy; his white blood cell count was elevated, hemoglobin low, and ferritin notably increased. What is the diagnosis and what would you do next?

Real-world adherence and discontinuation among Medicare beneficiaries initiating venetoclax vs. BTKis in relapsed/refractory chronic lymphocytic leukemia.

The treatment landscape for chronic lymphocytic leukemia (CLL) has been transformed by the availability of Bruton's tyrosine kinase inhibitors (BTKis) and the B-cell lymphoma 2 (BCL-2) inhibitor venetoclax. Despite clinical trial data supporting these novel oral agents, evidence evaluating real-world adherence is limited. This study used 2015-2019 Medicare claims data for elderly patients with relapsed/refractory CLL to assess differences in real-world adherence and discontinuation in the 12 months after treatment initiation. In the final sample of 711 venetoclax patients and 1,566 BTKi patients, we found that those initiating venetoclax tended to be younger (mean age 75.6 [SD 6.0] vs 77.6 [SD 6.9] years, p < .001) but had poorer clinical characteristics. After risk-adjustment, the venetoclax group had higher adherence (61.9% vs. 45.4%, p < .0001) and lower discontinuation when compared to the BTKi group (28.5% vs. 47.4%, p < .001). These favorable real-world findings underscore the importance of developing well-tolerated novel combinations for older adults.

Statin use, survival and incidence of thrombosis among older patients with polycythemia vera and essential thrombocythemia.

BACKGROUND: Polycythemia vera (PV) and essential thrombocythemia (ET) are linked to increased risk of cardiovascular morbidity and mortality. In addition to the reduction in of arterial thrombotic events, statins may prevent venous thrombosis including among patients with cancer. As previous registry- and claims-based studies revealed that the use of statins may improve the survival of patients with various malignancies we evaluated their impact on outcomes of older adults with PV and ET. METHODS: We identified 4010 older adults (aged 66-99 years at diagnosis) with PV (n = 1809) and ET (n = 2201) in a population-based cohort study using the Surveillance, Epidemiology, and End Results-Medicare database with median follow-up of 3.92 (interquartile range: 2.58-5.75) years. Propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) approaches were utilized to assess potential association between statins and overall survival. Multivariable competing risk models with death as a competing risk were used to evaluate possible relationship between statins and the incidence of thrombosis. RESULTS: 55.8% of the patients used statins within the first year after PV/ET diagnosis, and statin use was associated with a 22% reduction in all-cause mortality (PSM: hazard ratio [HR] = 0.78, 95% confidence interval [CI]: 0.63-0.98, p = 0.03; IPTW: HR = 0.79, 95% CI: 0.64-0.97, p = 0.03). Statins also reduced the risk of thrombosis in this patient population (PSM: HR = 0.63, 95% CI: 0.51-0.78, p < 0.01; IPTW: HR = 0.57, 95% CI: 0.49-0.66, p < 0.01) as well as in PV and ET subgroups. CONCLUSIONS: These findings suggest that it may be important to incorporate statins into the therapeutic strategy for older adults with PV and ET.

Helicobacter pylori-negative mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach: A clinicopathologic analysis.

OBJECTIVES: Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is historically associated with Helicobacter pylori (HP) infections in more than 80% of patients. However, the incidence of HP-negative MALT lymphoma has been increasing. The clinicopathologic features have not been well studied, and optimal management strategies remain unclear. METHODS: The pathology database was searched for primary gastric MALT lymphomas diagnosed from 2000 to 2017. The clinical data and the slides were reviewed. The cases were divided for analysis into those with a background of chronic gastritis with HP, chronic gastritis without HP, and without either a background of chronic gastritis or HP. RESULTS: Of 70 gastric MALT lymphoma cases identified, 26 (37% of total) had chronic gastritis and were positive for HP histologically (n = 23) or were HP positive by additional laboratory testing (n = 3). The remaining 44 (63% of total) cases were HP negative by histology. Within the HP-negative cases, 5 (11% of HP-negative cases) showed histologic gastritis while 39 (89% of HP-negative cases) did not have sufficient evidence of gastritis through review of slides (n = 18) or based on available pathology reports (n = 21). The HP-negative cases without gastritis had higher propensities to show a mass lesion on endoscopy compared with HP-positive cases (37.5% vs 11.1%, P = .02) at the initial diagnosis. The immunophenotype and rate of positive B-cell gene rearrangement were not significantly different between the 2 groups. While all HP-positive patients received antibiotics for HP eradication, treatment in the HP-negative group varied among antibiotics, radiation, rituximab, or chemotherapy. Among HP-negative patients with available follow-up, 13 (39%) showed disease recurrence, similar to the recurrence rate in HP-positive patients; however, no individual from either group has died of the disease thus far. CONCLUSIONS: The incidence of HP-negative MALT lymphoma is increasing, and in our practice, it is currently more common than HP-associated MALT lymphomas. The pathophysiology of HP-negative MALT lymphoma without chronic gastritis remains unclear. Follow-up data in our study suggest that the prognosis of these cases is excellent despite varied management modalities.

Brentuximab vedotin plus AVD for Hodgkin lymphoma: incidence and management of peripheral neuropathy in a multisite cohort.

Brentuximab vedotin (BV) in combination with doxorubicin, vinblastine, and dacarbazine (AVD) is increasingly used for frontline treatment of stage III/IV classical Hodgkin lymphoma (cHL). Peripheral neuropathy (PN) was the most common and treatment-limiting side effect seen in clinical trials but has not been studied in a nontrial setting, in which clinicians may have different strategies for managing it. We conducted a multisite retrospective study to characterize PN in patients who received BV + AVD for newly diagnosed cHL. One hundred fifty-three patients from 10 US institutions were eligible. Thirty-four patients (22%) had at least 1 ineligibility criteria for ECHELON-1, including stage, performance status, and comorbidities. PN was reported by 80% of patients during treatment; 39% experienced grade (G) 1, 31% G2, and 10% G3. In total, BV was modified in 44% of patients because of PN leading to BV discontinuation in 23%, dose reduction in 17%, and temporary hold in 4%. With a median follow-up of 24 months, PN resolution was documented in 36% and improvement in 33% at the last follow-up. Two-year progression-free survival (PFS) for the advanced-stage patients was 82.7% (95% confidence interval [CI], 0.76-0.90) and overall survival was 97.4% (95% CI, 0.94-1.00). Patients who discontinued BV because of PN did not have inferior PFS. In the nontrial setting, BV + AVD was associated with a high incidence of PN. In our cohort, which includes patients who would not have been eligible for the pivotal ECHELON-1 trial, BV discontinuation rates were higher than previously reported, but 2-year outcomes remain comparable.

Assessing unmet need among elderly Medicare Beneficiaries with Mantle cell lymphoma: an analysis of treatment patterns, survival, healthcare resource utilization, and costs.

Studies evaluating real-world outcomes and health care utilization for mantle cell lymphoma are limited. We utilized national Medicare claims (2009-2019) to examine treatment patterns, healthcare resource utilization, costs, and survival in 3664 elderly patients receiving 1 L treatment for MCL. Over a median follow-up of 2.8 years, 40.3% received at least 2 L treatment. The most common 1 L regimen was bendamustine-rituximab (50.1%), with increased use of BTKi-based regimens observed in 2 L (39.4%). Half (51.8%) of patients had an all-cause hospitalization within 12 months of initiating 1 L; hospitalization rates were higher in later lines. Healthcare costs were substantial and most costs (>80%) were MCL-related. Overall survival was poorer among later lines of treatment (median OS from initiation of 1 L: 53.5 months; 2 L: 22.0 months; 3 L: 11.8 months; 4 L: 7.8 months). These results suggest a large unmet need and future work should evaluate whether novel therapies have improved outcomes among elderly patients with MCL.

The COVID-19 Pandemic and In-Person Visit Rate Disruptions Among Patients With Hematologic Neoplasms in the US in 2020 to 2021.

Importance: The COVID-19 pandemic has led to a reduction in routine in-person medical care; however, it is unknown whether there have been any changes in visit rates among patients with hematologic neoplasms. Objective: To examine associations between the COVID-19 pandemic and in-person visits and telemedicine use among patients undergoing active treatment for hematologic neoplasms. Design, Setting, and Participants: Data for this retrospective observational cohort study were obtained from a nationwide electronic health record-derived, deidentified database. Data for patients with hematologic neoplasms who had received at least 1 systemic line of therapy between March 1, 2016, and February 28, 2021, were included. Treatments were categorized into 3 types: oral therapy, outpatient infusions, and inpatient infusions. The data cutoff date was April 30, 2021, when study analyses were conducted. Main Outcomes and Measures: Monthly visit rates were calculated as the number of documented visits (telemedicine or in-person) per active patient per 30-day period. We used time-series forecasting methods on prepandemic data (March 2016 to February 2020) to estimate expected rates between March 1, 2020, and February 28, 2021 (if the pandemic had not occurred). Results: This study included data for 24 261 patients, with a median age of 68 years (IQR, 60-75 years). A total of 6737 patients received oral therapy, 15 314 received outpatient infusions, and 8316 received inpatient infusions. More than half of patients were men (14 370 [58%]) and non-Hispanic White (16 309 [66%]). Early pandemic months (March to May 2020) demonstrated a significant 21% reduction (95% prediction interval [PI], 12%-27%) in in-person visit rates averaged across oral therapy and outpatient infusions. Reductions in in-person visit rates were also significant for all treatment types for multiple myeloma (oral therapy: 29% reduction; 95% PI, 21%-36%; P = .001; outpatient infusions: 11% reduction; 95% PI, 4%-17%; P = .002; inpatient infusions: 55% reduction; 95% PI, 27%-67%; P = .005), for oral therapy for chronic lymphocytic leukemia (28% reduction; 95% PI, 12%-39%; P = .003), and for outpatient infusions for mantle cell lymphoma (38% reduction; 95% PI, 6%-54%; P = .003) and chronic lymphocytic leukemia (20% reduction; 95% PI, 6%-31%; P = .002). Telemedicine visit rates were highest for patients receiving oral therapy, with greater use in the early pandemic months and a subsequent decrease in later months. Conclusions and Relevance: In this cohort study of patients with hematologic neoplasms, documented in-person visit rates for those receiving oral therapy and outpatient infusions significantly decreased during the early pandemic months but returned to close to projected rates in the later half of 2020. There were no statistically significant reductions in the overall in-person visit rate for patients receiving inpatient infusions. There was higher telemedicine use in the early pandemic months, followed by a decline, but use was persistent in the later half of 2020. Further studies are needed to ascertain associations between the COVID-19 pandemic and subsequent cancer outcomes and the evolution of telemedicine use for care delivery.

Cost-Effectiveness Analyses in AML: What Have We Learned, How Should This Impact Patient Care, and What Needs to Be Done in the Future?

Acute myeloid leukemia (AML) is the most common acute leukemia in adults in the United States and has seen the approval of several novel agents over the past decade. Similar to treatments for other hematologic and solid malignancies, these novel agents are costly. In the setting of finite financial resources in the healthcare system, the concept of cost-effectiveness analyses has been developed to compare the estimated costs and associated benefits expected with different interventions (eg, drugs, diagnostic tests, procedures). Although drug approvals in the United States are not based on budgetary considerations, cost-effectiveness analyses can inform health policy decisions, resource allocation, and societal debates. However, such analyses are only capturing parts of the costs and benefits to the healthcare system, payers, and consumers, and are based on modeling assumptions with inherent limitations. In addition, cost-effectiveness analyses for several of the novel agents approved for treatment of AML are limited and have reported conflicting results. This review uses cost-effectiveness analyses of azacitidine/venetoclax and liposomal cytarabine/daunorubicin as examples to review considerations and best practices when conducting and interpreting such studies. To ensure adequate interpretability of cost-effectiveness studies, transparency in the model inputs/assumptions, data sources, and funding is of great importance, as evidenced by the discrepant conclusions across studies. Furthermore, the perspective and the healthcare system from which a cost-effectiveness analysis is conducted are important to consider because practice patterns and drug prices between countries can be variable. However, with advances in health economic modeling techniques, adherence to best practices, and increasing public interest in these types of studies, cost-effectiveness analyses can become an important tool to inform various stakeholders in the healthcare system to allocate limited resources most efficiently.

Functional status and therapy for older adults with diffuse large B-cell lymphoma in nursing homes: A population-based study.

OBJECTIVES: To characterize the prevalence of functional and cognitive impairments, and associations between impairments and treatment among older patients with diffuse large B cell lymphoma (DLBCL) receiving nursing home (NH) care. METHODS: We used the Surveillance, Epidemiology, and End Results-Medicare database to identify beneficiaries diagnosed with DLBCL 2011-2015 who received care in a NH within -120 ~ +30 days of diagnosis. Multivariable logistic regression was used to compare receipt of chemoimmunotherapy (including multi-agent, anthracycline-containing regimens), 30-day mortality, and hospitalization between NH and community-dwelling patients, estimating odds ratios (OR) and 95% confidence interval (CI). We also examined overall survival (OS). Among NH patients, we examined receipt of chemoimmunotherapy based on functional and cognitive impairment. RESULTS: Of the eligible 649 NH patients (median age: 82 years), 45% received chemoimmunotherapy; among the recipients, 47% received multi-agent, anthracycline-containing regimens. Compared with community-dwelling patients, those in a NH were less likely to receive chemoimmunotherapy (OR: 0.34, 95%CI: 0.29-0.41), had higher 30-day mortality (OR: 2.00, 95%CI: 1.43-2.78) and hospitalization (OR: 1.51, 95%CI: 1.18-1.93), and poorer OS (hazard ratio: 1.36, 95%CI: 1.11-1.65). NH patients with severe functional (61%) or any cognitive impairment (48%) were less likely to receive chemoimmunotherapy. CONCLUSIONS: High rates of functional and cognitive impairment and low rates of chemoimmunotherapy were observed among NH residents diagnosed with DLBCL. Further research is needed to better understand the potential role of novel and alternative treatment strategies and patient preferences for treatment to optimize clinical care and outcomes in this high-risk population.

Older patients with chronic myeloid leukemia face suboptimal molecular testing and tyrosine kinase inhibitor adherence.

Tyrosine kinase inhibitor (TKI) use is critical in the care of patients with chronic myeloid leukemia (CML). Quantitative polymerase chain reaction (qPCR) testing for BCR-ABL1 every 3 months during the first year of TKI treatment is recommended to assure achievement of milestone response goals. Real-world evidence for the patterns of qPCR monitoring and TKI adherence in the older patient population is lacking. Using the Surveillance, Epidemiology, and End Results-Medicare database, we identified 1192 patients aged ≥66 years (median age, 74 years) with newly diagnosed CML who were followed up for ≥13 months from TKI initiation. In total, 965 patients (81.0%) had ≥1 test, with 425 (35.7%) and 540 (45.3%) of the patients tested during 1, 2, and ≥3 quarters (optimal monitoring) of the first year from TKI initiation, respectively. In multivariable analysis, diagnosis in later years and influenza vaccination before diagnosis, a proxy for health care access, were associated with optimal qPCR monitoring. Use of low-income subsidy and residing in census tracts with the lowest socioeconomic status were associated with less optimal monitoring. Patients with optimal monitoring were 60% more likely to be TKI adherent (odds ratio, 1.60; 95% CI, 1.11-2.31; P = .01) and had improved 5-year survival (hazard ratio, 0.66; 95% CI, 0.49-0.90; P < .01) than those without such monitoring. In this large, real-world study of CML management patterns, many older patients had suboptimal molecular monitoring, which was associated with decreased TKI adherence and worse survival.

Integrating 4 Measures to Evaluate Physical Function in Patients with Cancer (In4M): Protocol for a prospective study.

Introduction: Accurate, patient-centered evaluation of physical function in patients with cancer can provide important information on the functional impacts experienced by patients both from the disease and its treatment. Increasingly, digital health technology is facilitating and providing new ways to measure symptoms and function. There is a need to characterize the longitudinal measurement characteristics of physical function assessments, including clinician-reported physical function (ClinRo), patient-reported physical function (PRO), performance outcome tests (PerfO) and wearable data, to inform regulatory and clinical decision-making in cancer clinical trials and oncology practice. Methods and analysis: In this prospective study, we are enrolling 200 English- and/or Spanish-speaking patients with breast cancer or lymphoma seen at Mayo Clinic or Yale University who will receive standard of care intravenous cytotoxic chemotherapy. Physical function assessments will be obtained longitudinally using multiple assessment modalities. Participants will be followed for 9 months using a patient-centered health data aggregating platform that consolidates study questionnaires, electronic health record data, and activity and sleep data from a wearable sensor. Data analysis will focus on understanding variability, sensitivity, and meaningful changes across the included physical function assessments and evaluating their relationship to key clinical outcomes. Additionally, the feasibility of multi-modal physical function data collection in real-world patients with cancer will be assessed, as will patient impressions of the usability and acceptability of the wearable sensor, data aggregation platform, and PROs. Ethics and dissemination: This study has received approval from IRBs at Mayo Clinic, Yale University, and the U.S. Food & Drug Administration. Results will be made available to participants, funders, the research community, and the public. Registration Details: The trial registration number for this study is NCT05214144. Strengths & Limitations: This study addresses an important unmet need by characterizing the performance characteristics of multiple patient-centered physical function measures in patients with cancerPhysical function is an important and undermeasured clinical outcome. Scientifically rigorous capture and measurement of physical function constitutes a key component of cancer treatment tolerability assessment both from a regulatory and clinical perspective.This study will include patients with lymphoma or breast cancer receiving a broad range of cytotoxic chemotherapy regimens. While recruitment will occur at two academic sites, patients who ultimately receive treatment at local community sites will be included.A patient-centered health data aggregating platform facilitates the delivery of patient-reported outcome measures and collection of wearable data to researchers, while reducing patient burden compared to traditional patient-generated data collection and aggregation methodsHeterogeneity in patient willingness or comfort engaging with mobile products including smartphones and wearables, enrollment primarily at large academic centers, and the modest sample size are potential limitations to the external validity of the study.

DTRMWXHS-12, a novel Bruton tyrosine kinase inhibitor, in combination with everolimus and pomalidomide in patients with relapsed/refractory lymphomas: An open-label, multicenter, phase 1a/1b study.

Preclinical studies have shown augmented activity when combining Bruton tyrosine kinase inhibitors (BTKi) with inhibitors of mammalian target of rapamycin (mTOR) and immunomodulatory agents (IMiD). We conducted a phase 1, open-label study at five centers in USA to evaluate the safety of triplet BTKi/mTOR/IMiD therapy. Eligible patients were adults aged 18 years or older with relapsed/refractory CLL, B cell NHL, or Hodgkin lymphoma. Our dose escalation study used an accelerated titration design and moved sequentially from single agent BTKi (DTRMWXHS-12), doublet (DTRMWXHS-12 + everolimus), and then to triplet therapy (DTRMWXHS-12 + everolimus + pomalidomide). All drugs were dosed once daily on days 1-21 of each 28-day cycle. The primary goal was to establish the recommended phase 2 dose of the triplet combination. Between September 27, 2016, and July 24, 2019, a total of 32 patients with a median age of 70 years (range 46 to 94 years) were enrolled. No MTD was identified for monotherapy and the doublet combination. The MTD for the triplet combination was determined to be DTRMWXHS-12 200 mg + everolimus 5 mg + pomalidomide 2 mg. Responses across all studied cohorts were seen in 13 of 32 (41.9%). Combining DTRMWXHS-12 with everolimus and pomalidomide is tolerable and shows clinical activity. Additional trials could confirm benefit of this all-oral combination therapy for relapsed/refractory lymphomas.
