Physician reported treatment patterns and outcomes in metastatic bladder cancer in the USA: the CancerMPact® Survey 2020.

Aim: This study assessed physician-reported treatment patterns for metastatic bladder cancer. Materials & methods: A total of 106 USA-based physicians were surveyed in 2020 using the CancerMPact® online survey. Results: Among cisplatin-eligible patients, 86.1% received first-line (1L) platinum-containing chemotherapy, most commonly cisplatin plus gemcitabine, and 9.8% received immune checkpoint inhibitor monotherapy. Among cisplatin-ineligible patients, 46.5% received 1L platinum-containing chemotherapy, most commonly carboplatin plus gemcitabine and 46.2% received 1L immune checkpoint inhibitor therapy. Approximately 44% of patients who received 1L treatment received second-line (2L) therapy after progression. Conclusion: Platinum-containing chemotherapy was the most widely reported 1L treatment approach. A high proportion of patients received no 2L therapy. Validation in an updated dataset is warranted following the practice-changing approvals of avelumab 1L maintenance and additional 2L options.

In 2020, researchers surveyed 106 US doctors about how they treated people with advanced bladder cancer. Cisplatin, a chemotherapy drug, was the most common first treatment that was given to patients with advanced bladder cancer. For people who were unable to receive cisplatin, doctors preferred to prescribe a similar chemotherapy drug called carboplatin or an immunotherapy drug. Immunotherapies help the body's immune system to fight cancer cells. Most people treated by the surveyed doctors did not receive a second treatment if their cancer got worse. New treatments are now available for bladder cancer, such as the immunotherapy, avelumab. Avelumab is given after chemotherapy to try and stop the cancer from getting worse or coming back. More research is needed to further understand how bladder cancer is treated.

Clinical and Economic Outcomes in Patients With Metastatic Urothelial Carcinoma Receiving First-Line Systemic Treatment (the IMPACT UC I Study).

BACKGROUND: The IMPACT UC I study assessed real-world treatment patterns, outcomes, healthcare resource utilization (HCRU), and costs in patients with metastatic urothelial carcinoma (mUC) receiving first-line (1L) systemic treatment after the FDA approval of 1L immune checkpoint inhibitor (ICI) monotherapy. PATIENTS AND METHODS: This retrospective study used 100% Medicare fee-for-service claims from 1/1/2015 to 6/30/2019 to identify patients aged ≥18 years diagnosed with UC with evidence of metastatic disease, continuously enrolled for 6 months before and after initial diagnosis. Patients were grouped by 1L treatment: cisplatin-containing chemotherapy, carboplatin-containing chemotherapy, ICI monotherapy, or nonplatinum-containing therapy. Unadjusted time on 1L treatment (TOT), overall survival (OS), HCRU, and total healthcare costs were analyzed. RESULTS: Of 18 888 patients with mUC, 8630 (45.7%) had received identified 1L systemic treatment; platinum-containing chemotherapy was the most common (cisplatin-containing chemotherapy, 37.6%; carboplatin-containing chemotherapy, 30.2%). Cisplatin- and carboplatin-containing chemotherapy had the shortest time-to-treatment initiation (median, 1.7-3.0 months) and longest TOT (median, 4.0-4.3 months). Median OS was longest with cisplatin-containing chemotherapy (20.0 months) and shortest with ICI monotherapy (7.6 months). Cisplatin- and carboplatin-containing chemotherapy were associated with highest HCRU; total healthcare costs were approximately 2-fold higher with ICI monotherapy vs other 1L treatments ($10 359 vs $5042-$5709 per patient per month). CONCLUSION: 1L platinum-containing chemotherapy resulted in the longest median OS and highest HCRU, whereas 1L ICI treatment had the shortest median OS and the highest costs. Over 50% of patients diagnosed with advanced UC (aUC) received no systemic therapy, highlighting the importance of optimal 1L treatment decisions in aUC.

Mesenchymal stem cells exert their anti-asthmatic effects through macrophage modulation in a murine chronic asthma model.

Despite numerous previous studies, the full action mechanism of the pathogenesis of asthma remains undiscovered, and the need for further investigation is increasing in order to identify more effective target molecules. Recent attempts to develop more efficacious treatments for asthma have incorporated mesenchymal stem cell (MSC)-based cell therapies. This study aimed to evaluate the anti-asthmatic effects of MSCs primed with Liproxstatin-1, a potent ferroptosis inhibitor. In addition, we sought to examine the changes within macrophage populations and their characteristics in asthmatic conditions. Seven-week-old transgenic mice, constitutively overexpressing lung-specific interleukin (IL)-13, were used to simulate chronic asthma. Human umbilical cord-derived MSCs (hUC-MSCs) primed with Liproxstatin-1 were intratracheally administered four days prior to sampling. IL-13 transgenic mice demonstrated phenotypes of chronic asthma, including severe inflammation, goblet cell hyperplasia, and subepithelial fibrosis. Ly6C+M2 macrophages, found within the pro-inflammatory CD11c+CD11b+ macrophages, were upregulated and showed a strong correlation with lung eosinophil counts. Liproxstatin-1-primed hUC-MSCs showed enhanced ability to downregulate the activation of T helper type 2 cells compared to naïve MSCs in vitro and reduced airway inflammation, particularly Ly6C+M2 macrophages population, and fibrosis in vivo. In conclusion, intratracheal administration is an effective method of MSC delivery, and macrophages hold great potential as an additional therapeutic target for asthma.

Direct photoresponsive inhibition of a p53-like transcription activation domain in PIF3 by Arabidopsis phytochrome B.

Photoactivated phytochrome B (PHYB) binds to antagonistically acting PHYTOCHROME-INTERACTING transcription FACTORs (PIFs) to regulate hundreds of light responsive genes in Arabidopsis by promoting PIF degradation. However, whether PHYB directly controls the transactivation activity of PIFs remains ambiguous. Here we show that the prototypic PIF, PIF3, possesses a p53-like transcription activation domain (AD) consisting of a hydrophobic activator motif flanked by acidic residues. A PIF3mAD mutant, in which the activator motif is replaced with alanines, fails to activate PIF3 target genes in Arabidopsis, validating the functions of the PIF3 AD in vivo. Intriguingly, the N-terminal photosensory module of PHYB binds immediately adjacent to the PIF3 AD to repress PIF3's transactivation activity, demonstrating a novel PHYB signaling mechanism through direct interference of the transactivation activity of PIF3. Our findings indicate that PHYB, likely also PHYA, controls the stability and activity of PIFs via structurally separable dual signaling mechanisms.

Real-World Clinical and Economic Outcomes in Selected Immune-Related Adverse Events Among Patients with Cancer Receiving Immune Checkpoint Inhibitors.

BACKGROUND: With increased use of immune checkpoint inhibitors (ICIs) among patients with cancer, there is substantial interest in understanding clinical and economic outcomes and management of immune-related adverse events (irAEs). PATIENTS, MATERIALS, AND METHODS: A retrospective study was conducted using Premier Healthcare Database, a U.S. national hospital discharge database, from March 1, 2015, through December 31, 2017. The database comprises more than 880 million inpatient and hospital-based outpatient encounters, with more than 200 million unique patients reported by 966 hospitals. Patients with four solid tumors known to benefit from ICI therapy were included. The list of irAEs assessed was defined a priori per American Society of Clinical Oncology clinical guidelines for irAE management. Baseline irAE-related inpatient and outpatient visits were defined as the first inpatient or hospital-based outpatient visit with discharge diagnosis of any irAE of interest following confirmed ICI usage within 90 days prior to the baseline visit. Patients were followed for 90 days after baseline irAE-related inpatient discharge date or outpatient visit date to assess irAE-related inpatient admissions, all-cause in-hospital mortality, ICI reinitiation, and to determine costs and health care resource utilization. RESULTS: Records from 673,957 patients with four tumor types were reviewed for ICI therapy. Of 13,030 patients receiving ICIs, approximately 40% experienced at least one irAE, with a total of 10,121 irAEs occurring within 90 days of the ICI visit. The most frequent (>1,000 events) irAEs were anemia, impaired ventricular function with heart failure and vasculitis, thrombocytopenia, thyroid conditions, and peripheral edema. As might be expected, compared with those with baseline irAE-related outpatient visits, patients with baseline irAE-related inpatient visits had a significantly higher percentage of irAE-related inpatient admissions (23% vs. 14%) and all-cause in-hospital mortality (22% vs. 6%) and lower reinitiation of ICI therapy (31% vs. 71%). Baseline irAE-related inpatient visits had significantly higher mean costs ($29,477 vs. $5,718) with longer hospital stays (12.6 vs. 7.8 days). CONCLUSION: Findings from a U.S. national hospital discharge database suggest that irAEs in patients treated with ICIs are common, occur in multiples and with greater frequency in those with pre-existing comorbidities. Those with inpatient admissions have poorer outcomes. IMPLICATIONS FOR PRACTICE: The present work addressed the knowledge gap in understanding real-world outcomes of immune-related adverse events (irAEs) associated with immune checkpoint inhibitors (ICIs). Patients who experienced irAEs had significantly higher baseline comorbidities and were more likely to have immune-related or immune-compromised comorbid conditions. Patients with baseline irAE-related hospitalizations were more likely to be rehospitalized and to experience in-hospital mortality and less likely to reinitiate ICI treatment. Real-world patients are more diverse than clinical trials, and clinicians should consider both the efficacy and safety profile of ICI treatments, especially for patients with comorbidity conditions. Close monitoring is needed after patients have experienced an irAE.

Real-World Clinical Outcomes in Patients with Locally Advanced or Metastatic Merkel Cell Carcinoma Treated in U.S. Oncology Clinical Practices: Results from SPEAR-Merkel.

BACKGROUND: Immunotherapy (IO) has been associated with improved outcomes in patients with locally advanced Merkel cell carcinoma (laMCC) and metastatic Merkel cell carcinoma (mMCC). The primary objective of SPEAR-Merkel was to explore treatment patterns, clinical outcomes, and health care resource utilization (HCRU) in patients with laMCC or mMCC initiating first-line (1L) treatment with avelumab, non-avelumab IO, or chemotherapy in a U.S. community oncology setting. METHODS: Adult patients with laMCC or mMCC initiating 1L avelumab, non-avelumab IO, or chemotherapy from January 1, 2015, to March 31, 2019, were identified from the U.S. Oncology Network electronic health care record database and followed up through September 30, 2019. Baseline characteristics and HCRU were analyzed descriptively, including physician-stated overall response rate in the real-world clinical setting. Kaplan-Meier methods were used to measure duration of response, real-world progression-free survival (rwPFS), and overall survival (OS). RESULTS: Among the overall population (n = 94), 28 received 1L avelumab (9 laMCC, 19 mMCC), 26 received 1L non-avelumab IO (8 laMCC, 18 mMCC), and 40 received 1L chemotherapy (10 laMCC, 30 mMCC). The real-world overall response rate was 64.3%, 61.5%, and 42.5%, respectively. From 1L treatment initiation, median rwPFS was 11.4, 8.1, and 6.1 months, and median OS was 20.2 months, not reached, and 14.7 months for the respective cohorts. CONCLUSION: SPEAR-Merkel showed that patients with laMCC or mMCC treated with IO had improved outcomes compared with chemotherapy in clinical practice. The study provides insight on utilization and clinical outcomes associated with newer, more innovative therapies in clinical practice, which may help clinicians understand the variety of newer treatment options for both laMCC and mMCC. IMPLICATIONS FOR PRACTICE: To the authors' knowledge, SPEAR-Merkel is the first study to evaluate real-world clinical outcomes in patients with locally advanced Merkel cell carcinoma (laMCC) and metastatic Merkel cell carcinoma (mMCC) receiving first-line (1L) avelumab, non-avelumab immuno-oncology therapies, or chemotherapy in a real-world setting. SPEAR-Merkel showed clinical benefit for immuno-oncology therapies compared with chemotherapy. The study provides insight on uses and clinical outcomes associated with innovative therapies in clinical practice, which may help clinicians understand the variety of newer treatment options for both laMCC and mMCC. The study is of particular importance as it shows that chemotherapy is still being used as 1L treatment despite its inferior clinical and safety profile.

Effects of early vs delayed progression on clinical and economic outcomes in patients with metastatic renal cell carcinoma treated with tyrosine kinase inhibitors as first-line therapy: results from the IMPACT RCC claims data analysis.

BACKGROUND: A key therapeutic goal of metastatic renal cell carcinoma (mRCC) treatment is delayed disease progression. The degree to which early therapeutic success affects downstream outcomes is not well established. OBJECTIVE: To assess the clinical and economic impact of early vs delayed disease progression in patients with mRCC treated with first-line (1L) tyrosine kinase inhibitors (TKIs) followed by second-line (2L) therapy in the US Veterans Health Administration (VHA) database. METHODS: Adult patients newly diagnosed with mRCC who were treated with a TKI as 1L therapy and who progressed to 2L therapy from October 1, 2013, through March 31, 2018, were identified from the US VHA database. Patients were stratified by median time from initiation of 1L therapy to initiation of 2L therapy into early (median time or sooner)and delayed (longer than the median) progression cohorts. Clinical outcomes (time to 2L therapy discontinuation, time to third-line [3L] treatment initiation, and overall survival) were assessed descriptively, and health care resource utilization and costs were compared between patients in the early and those in the delayed progression cohorts. Survival analyses (Kaplan-Meier curves) were used to estimate descriptively the median time to discontinuation, time to next line of treatment, and time to death for each cohort. Multivariate analysis was performed to adjust for the influence of differences in cohort characteristics, and Cox proportional hazards models were used to descriptively assess the impact of predictive factors on clinical outcomes. RESULTS: 289 patients were included in the analysis: 145 in the early progression cohort and 144 in the delayed progression cohort. Baseline characteristics were similar between the early and delayed progression cohorts. Median time from 1L therapy initiation to 2L therapy discontinuation was 7.9 months in the early progression cohort and 18.0 months in the delayed progression cohort, whereas time from 1L therapy initiation to 3L therapy initiation was 9.4 and 21.8 months, respectively; overall survival was 19.7 and 36.4 months, respectively. Descriptive analysis revealed generally lower risks for 2L therapy discontinuation (HR = 0.40, 95% CI = 0.31-0.52), 3L therapy initiation (HR = 0.42, 95% CI = 0.32-0.55), and death (HR = 0.46, 95% CI = 0.33-0.64) for those with delayed progression. After adjustment for possible confounding factors, comparative analysis during the follow-up period showed that delayed progression was associated with a shorter median all-cause hospital length of stay (0.4 days vs 0.8 days for early progression; P = 0.0004), fewer pharmacy visits (3.57 vs 4.08 visits; P = 0.0266), and lower total health care costs ($10,342 vs $13,388; P = 0.0347) per patient per month. CONCLUSIONS: In patients with mRCC, early progression after 1L therapy initiation is associated with generally worse clinical outcomes and statistically significantly greater health care resource utilization and costs than delayed progression. This finding highlights the importance of initiating therapy with an optimal 1L treatment regimen that has been proven to delay disease progression.

The Impact of Adverse Events on Health Care Resource Utilization, Costs, and Mortality Among Patients Treated with Immune Checkpoint Inhibitors.

BACKGROUND: We investigated the association between adverse events (AEs) suspected to be immune-related and health care resource utilization, costs, and mortality among patients receiving programmed cell death 1/programmed cell death ligand 1 immune checkpoint inhibitor (ICI) monotherapy for urothelial carcinoma, renal cell carcinoma, non-small cell lung cancer, or Merkel cell carcinoma. PATIENTS AND METHODS: We conducted a retrospective cohort study using medical and pharmacy claims and enrollment information from U.S. commercial and Medicare Advantage with Part D enrollees in the Optum Research Database from March 1, 2014, through April 30, 2019. Claims were linked with mortality data from the Social Security Death Index and the National Death Index. Eligible patients had at least one ICI claim between September 1, 2014, and April 30, 2019. RESULTS: After adjusting for potential confounding variables, we found patients with AEs had more than double the risk of an inpatient stay (hazard ratio [HR], 2.2; 95% confidence interval [CI], 1.9-2.5) and an 80% higher risk of an emergency visit (HR, 1.8; 95% CI, 1.6-2.1) than patients without AEs. Adjusted 6-month total costs were $24,301 higher among patients with an AE versus those without ($99,037 vs. $74,736; 95% CI, $18,828-29,774; p < .001). Mean ± SD AE-related medical costs averaged $2,359 ± $7,496 per patient per month, driven by inpatient visits, which accounted for 89.9% of AE-related costs. Adjusted risk of mortality was similar in patients with and without AEs. CONCLUSION: Patients with AEs had higher risks of hospitalizations, emergency room visits, and higher health care costs, driven by inpatient stays, than patients without AEs. The adjusted risk of mortality was similar between the two cohorts. IMPLICATIONS FOR PRACTICE: Patients taking immune checkpoint inhibitors (ICIs) who had adverse events (AEs) had significantly higher health care costs and utilization, driven by inpatient stays, compared with patients who did not. Given this high cost associated with AEs and the differences in the side effect profile of ICIs versus traditional chemotherapy, it is important for physicians to be cognizant of these differences when treating patients with ICIs. Ongoing evaluation, earlier recognition, and more effective, multidisciplinary management of AEs may improve patient outcomes and reduce the need for costly inpatient stays.

Clinical Outcomes, Costs, and Healthcare Resource Utilization in Patients with Metastatic Merkel Cell Carcinoma Treated with Immune Checkpoint Inhibitors vs Chemotherapy.

PURPOSE: Merkel cell carcinoma (MCC) is a rare, aggressive skin cancer with poor prognosis. This study compared patient characteristics, comorbidities, adverse events (AEs), treatment persistence, healthcare resource utilization (HRU) and costs in patients with metastatic MCC (mMCC) treated with immune checkpoint inhibitors (ICIs) or recommended chemotherapy per 2018 National Comprehensive Cancer Network (NCCN) Guidelines. PATIENTS AND METHODS: A retrospective, observational study was conducted using data from 3/1/2015 through 12/31/2017 from the Premier Healthcare Database, a US hospital discharge database. The study included patients aged ≥12 years with International Classification of Diseases Codes for MCC and metastasis, categorized by their first treatment (index) during the study period (ICI or NCCN-recommended chemotherapy [chemotherapy]). Patient, hospital, and visit characteristics were assessed at the index date and Charlson Comorbidity Index (CCI) score and comorbidities during a 6-month look-back period. Clinical outcomes, including AEs and treatment persistence were assessed over 90 days and HRU and costs over 180 days post-index. RESULTS: Of 75 patients with mMCC receiving ICIs (n=37) or chemotherapy (n=38), mean age was ≈73 years, and 21.3% had a history of immune-related (IR) conditions. Overall, ICI- and chemotherapy-treated patients were similar in most baseline characteristics, IR comorbidities, and CCI score. However, more ICI patients (46%) than chemotherapy patients (26%) persisted on treatment over 90-day follow-up, odds ratio (95% CI): 2.04 (0.93, 4.47), P=0.07. Over 180-day follow-up, 33% of patients had an inpatient admission with mean length of stay (LOS) ≈2 days shorter for ICI vs chemotherapy (not statistically significant). Total costs, primarily driven by pharmacy costs, were higher for ICIs than chemotherapy; other departmental costs were similar between treatment groups. CONCLUSION: In a real-world setting, patients with mMCC receiving ICIs had higher treatment persistence over 90 days, shorter inpatient LOS and similar departmental cost (excluding pharmacy cost) than those receiving chemotherapy.

Real-World Outcomes Among US Veterans Health Administration Patients Newly Diagnosed with Metastatic Renal Cell Carcinoma and Treated with First-Line Monotherapy.

INTRODUCTION: Substantial unmet needs exist among patients with metastatic renal cell carcinoma (mRCC). This retrospective study evaluated treatment patterns as well as clinical and economic outcomes associated with first-line monotherapy among patients with mRCC in the USA. METHODS: Newly diagnosed patients with mRCC initiating at least one first-line therapy (1L) from 1 October 2013 to 31 March 2018 (index date = 1L start date) were identified from the US Veterans Health Administration database. Treatment patterns, clinical outcomes (time to next treatment [TNT] defined by earliest of switch to non-index therapy or re-initiation of index therapy after a more than 90-day gap, time to treatment discontinuation [TTD], overall survival [OS]), and costs were evaluated among patients treated with tyrosine kinase inhibitors (TKI), mammalian target of rapamycin inhibitors (mTOR), immune checkpoint inhibitors (ICI), and other monotherapies. Standard descriptive statistics were presented. The Kaplan-Meier method was used to evaluate clinical outcomes. RESULTS: Of 759 patients (median age 68.0 years), 85.0%, 8.0%, 4.3%, and 2.6% were treated with TKI, mTOR, ICI, or other therapy in 1L, respectively. Advancement rates (to second-line [2L] therapy) ranged from 10.0 (ICI) to 45.1 per 100 person years (TKI). The 12-month OS rates ranged from 47.4% (TKI) to 67.7% (mTOR). The median TNT ranged from 3.8 (mTOR) to 9.6 months (ICI), and median TTD ranged from 2.3 (mTOR) to 4.7 months (TKI). Total all-cause mean costs per patient per month ranged from $12,466 (mTOR) to $19,812 (ICI). CONCLUSION: These results indicate high unmet medical needs among patients with mRCC treated with 1L monotherapies. Novel combination therapies (e.g., ICI + ICI, ICI + TKI) may improve front-line outcomes for patients with poor prognoses.

Real-world clinical outcomes with first-line avelumab in locally advanced/metastatic Merkel cell carcinoma in the USA: SPEAR-Merkel.

Aim: To assess clinical outcomes in patients with locally advanced (la) or metastatic (m) Merkel cell carcinoma (MCC) initiating first-line (1L) avelumab in a USA community oncology setting. Materials & methods: Adults with laMCC or mMCC initiating 1L avelumab were identified from The US Oncology Network electronic health record database and chart review. Results: Median overall survival and progression-free survival were not reached in laMCC (n = 9) vs 20.2 and 10.0 months in mMCC (n = 19); response rates were similar (66.7% vs 63.2%). Conclusion: This is the first study to show clinical benefit in patients with laMCC receiving 1L avelumab in a US real-world setting. Response rates in patients with mMCC were consistent with pivotal trials.

Lay abstract Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer. Because MCC progresses quickly, many patients have a poor prognosis. Avelumab is a type of drug that helps the patient's immune system to fight cancer. Avelumab was the first such drug approved by the US FDA for treating metastatic MCC based on the results of the JAVELIN Merkel 200 clinical trial. In SPEAR-Merkel, we studied how MCC patients with locally advanced as well as metastatic disease responded when they were treated with first-line avelumab in a real-world setting. These patients were from oncology practices in communities throughout the USA. Overall response rates in SPEAR-Merkel were comparable between patients with locally advanced and metastatic MCC. Importantly, we found that these patients experienced survival benefit similar to patients in the JAVELIN Merkel 200 (part B) study and other real-world studies.

Real-world symptoms, disease burden, resource use and quality of life in US patients with advanced renal cell cancer.

Aim: To assess symptoms, healthcare resource utilization and health-related quality of life in advanced renal cell carcinoma (aRCC) clinical practice. Materials & methods: The USA point-in-time survey of physicians and patients was conducted between February and September 2019. Results: Data were available for 227 patients. Mean (standard deviation) number of symptoms was 3.4 (3.2); differences were observed across International Metastatic RCC Database Consortium risk categories (p < 0.001), with fewer symptoms in favorable-risk patients. Disease burden, measured by greater healthcare resource utilization and worse health-related quality of life, was high, particularly in International Metastatic RCC Database Consortium intermediate- or poor- versus favorable-risk patients. In total, 45 patients (21.6%) were hospitalized due to aRCC within a 6-month period, 35 (16.8%) had one hospitalization and ten (4.8%) experienced ≥2 hospitalizations due to aRCC. Mean (standard deviation) 19-Item Functional Assessment of Cancer Therapy Kidney Symptom Index score was 53.6 (13.2) for this population, significantly lower than the reference value (59.8; p < 0.001). Conclusion: A clear need exists for improved disease management in patients with aRCC.

Lay abstract Late-stage/advanced renal cell carcinoma (aRCC) is kidney cancer that has spread to other body parts. aRCC is expensive to treat and affects patients in many ways. New treatments have become available, including tyrosine kinase inhibitors and immuno-oncology therapies. The type of treatment recommended depends on the patient's International Metastatic RCC Database Consortium risk score. This is a way of classifying patients as having a good, intermediate or poor survival risk. We asked physicians questions about their patients such as their age, how long they had aRCC, their treatment and symptoms, and asked patients how aRCC affected their lives, including how often they visited doctors and hospitals. aRCC had the greatest effect on patients with poor-risk scores. Those patients had more symptoms and worse quality of life than patients with intermediate or good risk scores. Treatment also affected patients' lives, although not as much as risk score. Patients with aRCC need better treatment options to help improve their quality of life.

Treatment Sequencing Patterns in Patients with Metastatic Urothelial Cancer Treated in the Community Practice Setting in the United States: SPEAR-Bladder (Study informing treatment Pathway dEcision in bladder cAnceR).

PURPOSE: Clinical trial evidence has affirmed the role for immuno-oncology (IO) treatment for locally advanced or metastatic urothelial carcinoma (la/mUC). This Study informing treatment Pathway dEcision in bladder cAnceR (SPEAR-Bladder) aimed to provide insight into the optimal sequencing of IO treatments among la/mUC patients treated in the US Oncology Network. PATIENTS AND METHODS: This was a retrospective analysis of adult patients with la/mUC who initiated first-line chemotherapy followed by either IO therapy (C-IO subgroup) or chemotherapy (C-C subgroup) between 01/01/2015 and 04/30/2017 and included a potential follow-up period through 06/30/2017. Data were sourced from iKnowMed electronic health records. Patient and treatment characteristics were assessed descriptively, with Kaplan-Meier methods used to evaluate time-to-event outcomes, including overall survival (OS). RESULTS: A total of 117 patients were included in this analysis (median age 69 years, 74.4% male, 88.0% Caucasian): 79 and 38 patients were in the C-IO and C-C subgroups, respectively. The median OS was 19.2 months among patients who received the C-IO sequence and 11.9 months among those who received the C-C treatment sequence. CONCLUSION: These results suggest that patients who received the C-IO treatment sequence had notable improvement in OS compared with those who received the C-C sequence. In light of the rapidly evolving therapeutic landscape, further investigation will be required to determine how best to select the optimal therapeutic regimen and sequencing for patients with la/mUC.

Real-world outcomes among US Merkel cell carcinoma patients initiating immune checkpoint inhibitors or chemotherapy.

Aim: Retrospectively assessed treatment patterns and clinical and economic outcomes in Merkel cell carcinoma (MCC) patients receiving recommended first-line regimens. Materials & methods: MCC patients newly treated with either immune checkpoint inhibitors (ICIs) or chemotherapies (CTs) were selected from the Veterans Health Administration database (2013-2018); 74 patients (ICIs: 20 and CTs: 54) were selected. Results: Median duration of therapy was 300 days for ICIs and 91 days for CTs. Time to next treatment was 245 and 184 days, respectively. Mean total (per patient per month) costs were $15,306 (ICIs) and $10,957 (CTs), of which 51% and 86%, respectively, were non-MCC therapy-related costs. Conclusion: Despite higher costs, utilization of ICIs in first-line MCC shows clinical advantages over CTs in the real world.

Treatment patterns, outcomes and clinical characteristics in advanced renal cell carcinoma: a real-world US study.

Aim: Assessing treatment patterns, outcomes and clinical characteristics in advanced renal cell carcinoma clinical practice. Materials & methods: A US cross-sectional physician survey conducted February-September 2019. Results: Surveyed physicians reported first-line treatment of 445 patients involving tyrosine kinase inhibitor monotherapy (51.0%), immuno-oncology (IO/IO combination) therapy (25.8%) or other regimens (23.1%). A total of 60.9% had physician-assessed IMDC risk. Of these 61.9, 50.9 and 27.6% of patients with favorable, intermediate and poor risk, respectively, received tyrosine kinase inhibitor monotherapy. A total of 16.7, 26.9 and 34.5% of patients with favorable, intermediate or poor risk received IO/IO combination therapy. Complete/partial responses (∼35% patients) remained comparable across first-line treatments. Conclusion: Guideline-recommended therapies are not widely prescribed. Many patients experienced poor clinical outcomes highlighting a need for more effective treatments.

A real-world, cross-sectional, community survey of symptoms and health-related quality of life of adults with acute myeloid leukemia.

Aim: We used Adelphi Real World Disease-Specific Programme data to characterize adults with newly diagnosed or relapsed/refractory de novo acute myeloid leukemia (AML). Materials & methods: Community-practice hematologists/oncologists completed patient record forms for their regular AML patients. Patients were invited to complete patient self-completion forms including 3-Level EuroQol 5-Dimensions (EQ-5D-3L) and Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu) questionnaires. Results: Physicians provided patient record forms for 389 patients (339 newly diagnosed, 50 relapsed/refractory); 68 patients completed patient self-completion forms. Mean EQ-5D visual-analog scale and index and FACT-General scores were significantly lower than US population norms (p < 0.0001); health-related quality of life (HRQoL) scores were generally lower than 11 other cancers. Conclusion: HRQoL impairment is grave in AML. Efforts are needed to improve HRQoL in affected patients.
