Real-world treatment patterns and clinical outcomes in patients treated with eribulin after prior phosphoinositide 3-Kinase inhibitor treatment for metastatic breast cancer.

PURPOSE: In 2010, the US Food and Drug Administration approved eribulin for the treatment of metastatic breast cancer (MBC). Since then, the treatment landscape has evolved with many new therapy classes, a more recent one being the small molecule inhibitors of phosphoinositide 3 kinase (PI3K). We sought to characterize the treatment patterns and clinical outcomes of patients with MBC who received eribulin following prior treatment with a PI3K inhibitor. METHODS: A retrospective cohort study based on medical record review included MBC patients who initiated eribulin between March 2019 and September 2020 following prior treatment with a PI3K inhibitor was conducted. Patient demographics, treatment characteristics, and clinical outcomes were analyzed descriptively. Real-world progression-free survival (rwPFS) and overall survival (OS) were estimated from the initiation of eribulin therapy using Kaplan-Meier analyses. RESULTS: 82 eligible patients were included. Patients' median age at eribulin initiation was 62 years; 86.5% had hormone receptor-positive, human epidermal growth factor receptor 2-negative tumors. Eribulin was most often administered in the second or third line (82.9%) in the metastatic setting. Best overall response on eribulin was reported as complete or partial response in 72% of the patients. The median rwPFS was 18.9 months (95% confidence interval [CI], 12.4-not estimable); median OS was not reached. The estimated rwPFS and OS rates at 12 months were 63.3% (95% CI, 50.5-73.7) and 82.6% (95% CI, 72.4-89.3), respectively. CONCLUSION: Our real-world study suggests that eribulin may be a potential treatment option for MBC patients who fail a prior PI3K inhibitor.

Effectiveness of standard treatments in non-small-cell lung cancer with METexon14 skipping mutation: a real-world study.

Aim: To assess real-world clinical outcomes with standard therapies for advanced non-small-cell lung cancer (aNSCLC) with METexon14 skipping mutation (METex14). Methods: In an oncologists-led retrospective review of medical records, data were abstracted and analyzed for patients initiating first-line (1L) systemic therapy after 1 January 2017. Results: In total 287 aNSCLC patients with METex14, the real-world best overall response rate was 73.4% for capmatinib (n = 146), 68.8% for immunotherapy (IO) monotherapy (n = 48), 52.0% for chemotherapy (CT, n = 30), and 54.8% for IO + CT (n = 63). As compared with capmatinib, patients receiving IO (hazard ratio [HR]: 1.57; 95% CI: 0.77-3.20; p = 0.220), CT (HR: 2.41; 95% CI: 1.19-4.85; p = 0.014) and IO + CT (HR: 2.33; 95% CI: 1.35-4.04; p = 0.003) had higher rates of progression. Further, patients receiving CT (HR: 4.43; 95% CI: 1.54-12.75; p = 0.006) and IO + CT (HR: 3.53, 95% CI: 1.41-8.85; p = 0.007) had higher rates of mortality than patients receiving capmatinib. Conclusion: The study showed better clinical outcomes with capmatinib than other standard therapies in 1L setting for aNSCLC harboring METex14.

Real-world study that investigated the outcomes of different therapies used to treat non-small-cell lung cancer patients with mesenchymal-epithelial transition exon 14 skipping mutationWhat is this article about? A real-world study that investigated clinical outcomes in patients with diagnosis of advanced non-small-cell lung cancer (aNSCLC) with mesenchymal-epithelial transition exon 14 (METex14) skipping­a rare form of genetic mutation­who received treatment with one of the commonly used therapies for this disease: immunotherapy, chemotherapy, immunotherapy + chemotherapy combination and capmatinib, which is a highly selective inhibitor of MET tyrosine kinase protein involved in the growth of cancer cells.What were the results? The study showed that, in general, patients treated with capmatinib as the frontline therapy more frequently achieved a clinical response in the form of complete tumor resolution or tumor shrinkage, had a lower risk of disease worsening and lived longer than patients who were treated with immunotherapy, chemotherapy or immunotherapy + chemotherapy combination.What do the results of the study mean? This study suggests that capmatinib is effective in treating patients with aNSCLC with METex14 skipping who have not been treated with another anticancer therapy previously. It provides evidence to support the use of capmatinib in the frontline setting and may inform clinical decision-making in routine practice.

Real-World Effectiveness of Lenvatinib in Hepatocellular Carcinoma Patients with Nonalcoholic Steatohepatitis.

Hepatocellular (HCC) is the most common type of primary liver cancer and the fourth most common cause of cancer-related deaths globally.1 Although most cases of HCC were historically attributed to underlying chronic viral hepatitis, nonalcoholic fatty liver disease is projected to become the most common risk factor for HCC with the rising prevalence of obesity and diabetes mellitus and increasing availability of effective treatments for hepatitis B and C infection.2 Although patients with viral and nonviral HCC seem to have similar overall prognosis,3 prior data have suggested possible differential efficacy of systemic therapies by liver disease etiology. For example, sorafenib was shown to have greater efficacy in patients with chronic hepatitis C infection than other etiologies.4 The aim of our descriptive study was to report the effectiveness of lenvatinib in a real-world cohort of patients with nonalcoholic steatohepatitis (NASH)-related HCC.

Real-world outcomes in non-small-cell lung cancer patients with MET Exon 14 skipping mutation and brain metastases treated with capmatinib.

Aim: To assess real-world clinical outcomes in patients with non-small-cell lung cancer with MET exon 14 skipping mutation and brain metastases (BM) who received capmatinib, a recently approved MET inhibitor, in routine US clinical practice. Materials & methods: Patient data were collected using a retrospective medical record review, led by participating oncologists. Eligible patients initiated treatment with capmatinib in any line, after BM diagnosis, between May 2020 and June 2021. Data on real-world overall response rate (rwORR) and real-world progression-free survival (rwPFS) were descriptively analyzed. Results: 68 eligible patients were analyzed. In patients treated with first-line (1L) capmatinib (n = 55), the rwORR was 90.9% systemically and 87.3% intracranially; median systemic rwPFS was 14.1 months. Among radiation-naive patients on 1L capmatinib (n = 20), rwORR was 85.0%, both systemically and intracranially; median systemic rwPFS was 14.1 months. Conclusion: This study showed substantial systemic and intracranial effectiveness for capmatinib in real-world setting; findings were consistent for RT-naive patients.

Systematic assessment of process analytical technologies for biologics.

The application of process analytical technology (PAT) for biotherapeutic development and manufacturing has been employed owing to technological, economic, and regulatory advantages across the industry. Typically, chromatographic, spectroscopic, and/or mass spectrometric sensors are integrated into upstream and downstream unit operations in in-line, on-line, or at-line fashion to enable real-time monitoring and control of the process. Despite the widespread utility of PAT technologies at various unit operations of the bioprocess, a holistic business value assessment of PAT has not been well addressed in biologics. Thus, in this study, we evaluated PAT technologies based on predefined criteria for their technological attributes such as enablement of better process understanding, control, and high-throughput capabilities; as well as for business attributes such as simplicity of implementation, lead time, and cost reduction. The study involved an industry-wide survey, where input from subject matter industry experts on various PAT tools were collected, assessed, and ranked. The survey results demonstrated on-line liquid Chromatography (LC), in-line Raman, and gas analysis techniques are of high business value especially at the production bioreactor unit operation of upstream processing. In-line variable path-length UV/VIS measurements (VPE), on-line LC, multiangle light scattering (MALS), and automated sampling are of high business value in Protein A purification and polishing steps of the downstream process. We also provide insights, based on our experience in clinical and commercial manufacturing of biologics, into the development and implementation of some of the PAT tools. The results presented in this study are intended to be helpful for the current practitioners of PAT as well as those new to the field to gauge, prioritize and steer their projects for success.

Real-world clinical outcomes of patients with myelofibrosis treated with ruxolitinib: a medical record review.

Aim: To assess real-world ruxolitinib treatment patterns and outcomes in patients diagnosed with primary or secondary myelofibrosis. Materials & methods: Patient medical records were reviewed in six countries. Results: Eligible patients (n = 469) had a mean age of 63.5 years, and most were male (66.5%) with primary myelofibrosis (78.5%). Median duration of ruxolitinib treatment was 13.1 months; 40% of patients initiated treatment at the recommended dose. The Kaplan-Meier estimate of median survival from ruxolitinib initiation was 44.4 months (95% CI, 38.8-50.2 months). Approximately one quarter (23%) of patients continued ruxolitinib after progression. Conclusion: These results suggest an unmet need for more effective treatments for patients with myelofibrosis who failed ruxolitinib.

Real-world effectiveness of lenvatinib monotherapy among unresectable hepatocellular carcinoma patients in the USA.

Aim: This study evaluated the effectiveness of lenvatinib monotherapy for first-line treatment of unresectable hepatocellular carcinoma (uHCC) in a real-world setting. Materials & methods: This retrospective cohort study included patients who initiated lenvatinib monotherapy as first-line treatment for uHCC (n = 233). Clinical outcomes included provider-reported best response, progression-free survival (PFS) and overall survival (OS). PFS and OS were estimated using Kaplan-Meier methods. Results: Most patients (67.8%) were male. A total of 44.6% had Child-Pugh A and 39.1% had Child-Pugh B. Dose reductions were reported in 9%. Median PFS and OS were not reached. At 6 and 12 months, landmark PFS were 85.1 and 64.9%, respectively; landmark OS were 91.8 and 72.6%, respectively. Conclusion: These results affirm the clinical effectiveness of first-line lenvatinib monotherapy in uHCC.

Lay abstract Lenvatinib is a targeted therapy that prevents tumor growth. It was approved for the treatment of advanced liver cancer in 2018, but few studies have examined how it is used in everyday clinical practice, especially in the USA. In this study, we reviewed the medical records of 233 patients in the USA with unresectable hepatocellular carcinoma, who were treated with lenvatinib in first line to better understand its effectiveness and use in real-world care. We collected information on how long they were on treatment and time to tumor progression and/or death. Overall, our study found that in this demographically and clinically diverse sample, results affirm findings from prior studies that found lenvatinib is an effective treatment for patients with unresectable hepatocellular carcinoma.

POLARIS: a prospective, multicenter, noninterventional study assessing palbociclib in hormone receptor-positive advanced breast cancer.

This report describes the rationale, purpose and design of the POLARIS study. POLARIS is an ongoing noninterventional, prospective, multicenter study. Female and male patients in the USA and Canada diagnosed with hormone receptor-positive/HER2-negative metastatic breast cancer were enrolled in the study and treated with the cyclin-dependent kinase 4/6 inhibitor palbociclib when hormone receptor-positive/HER2-negative metastatic breast cancer was deemed to be indicated by their physician. The study will provide real-world data on palbociclib prescribing and treatment patterns in routine clinical practice, associated clinical outcomes, treatment sequencing in the advanced/metastatic setting, patient quality of life and geriatric-specific assessments. The tumor genomic landscape in relation to clinical outcomes will be explored. POLARIS will identify benefits and side effects of palbociclib across multiple lines of therapy and in discrete subsets of patients. Clinical Trial Registration: NCT03280303 (ClinicalTrials.gov).

Treatment patterns and characteristics of patients with migraine in Japan: A retrospective analysis of health insurance claims data.

OBJECTIVE: To describe treatment patterns of migraine patients in the Japan Medical Data Center (JMDC) database. METHODS: Patients aged ≥18 years with ≥1 inpatient or ≥2 outpatient migraine diagnoses, ≥1 outpatient diagnosis and ≥1 migraine-specific acute treatment (triptan or ergotamine), or ≥2 migraine-specific acute treatments from 1 May 2011 to 30 April 2014 were identified. Patients were required to be enrolled in a health plan for ≥1 year before and after the index date. The first migraine diagnosis or acute treatment defined the index date. Patients were stratified by the migraine treatments observed after the index date (i.e. migraine-specific acute treatment only [AT], prophylactic with or without migraine-specific acute treatment [PT], or no treatment [NT]) and described regarding the first migraine treatment regimen and subsequent treatment patterns during up to 1 year of follow-up. RESULTS: A total of 16,443 patients met the eligibility criteria (9873 AT, 3022 PT, and 3548 NT). AT patients had mean (SD) 10.3 (20.5) acute treatment days during 1-year follow-up, and 81.9% received triptans. When assessing the first migraine treatment regimen during follow-up in PT patients, 29.2% received prophylactic treatment only and 51.7% received both acute and prophylactic treatment. Calcium-channel blockers with or without concomitant triptans (34.4%) were the most common first regimen. Approximately 62.2% discontinued initial prophylactic treatment after an average of 61.2 days (SD = 65.3) of persistent treatment. Among discontinuers, 15.2% reinitiated original treatment and 7.0% switched treatment post-discontinuation within a year, while the remaining patients did not receive prophylactic therapy following discontinuation. CONCLUSIONS: Among Japanese migraine patients, prophylactic use was low and associated with a high rate of discontinuation following a brief treatment period. Many patients reinitiated or switched treatment following discontinuation, while a significant proportion of patients remained discontinued from prophylactic therapy, suggesting a high unmet need.

Achievement of Target A1C <7.0% (<53 mmol/mol) by U.S. Type 2 Diabetes Patients Treated With Basal Insulin in Both Randomized Controlled Trials and Clinical Practice.

OBJECTIVE: Many patients with type 2 diabetes do not reach glycemic goals despite basal insulin treatment. This study assessed the achievement of a target A1C <7.0% (<53 mmol/mol) after initiation of basal insulin in two settings. METHODS: This was a retrospective analysis of pooled randomized controlled trial (RCT) data, from 11 24-week studies of patients initiating basal insulin performed between 2000 and 2005 and of outpatient electronic medical record (EMR) data from the General Electric Centricity database for insulin-naive patients initiating basal insulin between 2005 and 2012. Baseline characteristics stratified by target A1C and fasting plasma glucose (FPG) attainment were compared descriptively. RESULTS: In the RCT dataset, 49.0% of patients failed to achieve the target A1C at 6 months versus 72.4% and 72.9% at 6 and 12 months in the EMR dataset, respectively. Despite this, in the RCT dataset, 79.4% of patients achieved the target A1C and/or an FPG <130 mg/dL. In the EMR dataset, only 47.6% and 47.3% of patients achieved an A1C <7.0% and/or FPG <130 mg/dL at 6 and 12 months, respectively. Overall, patients with an A1C >7.0% had a longer diabetes duration and were more likely to be female, nonwhite, and self-funding or covered by Medicaid. Among patients with an A1C >7.0%, more RCT patients (58.0%) had an FPG <130 mg/dL than EMR patients at 6 months (27.8%) and 12 months (27.7%). CONCLUSION: Unmet needs remain after basal insulin initiation, particularly in real-world settings, where many patients require further insulin titration. In both populations, patients failing to achieve the target A1C despite attaining an FPG <130 mg/dL require interventions to improve postprandial control.

Treatment Patterns, Statin Intolerance, and Subsequent Cardiovascular Events Among Japanese Patients With High Cardiovascular Risk Initiating Statin Therapy.

BACKGROUND: This study examined treatment patterns, possible statin intolerance, and incidence of cardiovascular events (CVEs) in 2 cohorts of patients with high cardiovascular risk (i.e., patients with atherosclerotic cardiovascular disease [ASCVD] and patients with diabetes mellitus).Methods and Results:A retrospective cohort study examined adults initiating either a statin or ezetimibe from 1 January 2006 to 31 May 2014 in the Japan Medical Data Center database. The first observed statin or ezetimibe prescription defined the index date. Patients had ≥12 months of pre- and post-index date plan enrollment. Two high-risk cohorts, the ASCVD cohort and diabetes cohort, were created based on diagnoses observed during the 12 months' pre-index date. Treatment patterns, possible statin intolerance, and incidence of CVEs were reported. In the ASCVD cohort (n=5,302), 32.9% discontinued therapy, 7.7% switched to a non-index statin or non-statin lipid-lowering therapy, and 11.2% augmented index therapy in the 12 months' post-index date; only 0.3% were using high-intensity statins and 10% had possible statin intolerance. Also, 8.1% had any new CVE during the follow-up period. Treatment patterns and incidence of CVEs among the diabetes cohort were similar to those of the ASCVD cohort. CONCLUSIONS: High cardiovascular risk Japanese patients had frequent treatment modifications, although use of high-intensity statin doses was rare. These patterns may indicate that alternative therapies for lipid lowering are needed.

Process development of a FGF21 protein-antibody conjugate.

A scalable, viable process was developed for the Fibroblast Growth Factor 21 (FGF21) protein-antibody conjugate, CVX-343, an extended half-life therapeutic for the treatment of metabolic disease. CVX-343 utilizes the CovX antibody scaffold technology platform that was specifically developed for peptide and protein half-life extension. CVX-343 is representative of a growing number of complex novel peptide- and protein-based bioconjugate molecules currently being explored as therapeutic candidates. The complexity of these bioconjugates, assembled using well-established chemistries, can lead to very difficult production schemes requiring multiple starting materials and a combination of diverse technologies. Key improvements had to be made to the original CVX-343 Phase 1 manufacturing process in preparation for Phase 3 and commercial manufacturing. A strategy of minimizing FGF21A129C dimerization and stabilizing the FGF21A129C Drug Substance Intermediate (DSI), linker, and activated FGF21 intermediate was pursued. The use of tris(2-carboxyethyl)phosphine (TCEP) to prevent FGF21A129C dimerization through disulfide formation was eliminated. FGF21A129C dimerization and linker hydrolysis were minimized by formulating and activating FGF21A129C at acidic instead of neutral pH. An activation use test was utilized to guide FGF21A129C pooling in order to minimize misfolds, dimers, and misfolded dimers in the FGF21A129C DSI. After final optimization of reaction conditions, a process was established that reduced the consumption of FGF21A129C by 36% (from 4.7 to 3.0 equivalents) and the consumption of linker by 55% (from 1.4 to 0.95 equivalents for a smaller required amount of FGF21A129C ). The overall process time was reduced from ∼5 to ∼3 days. The product distribution improved from containing ∼60% to ∼75% desired bifunctionalized (+2 FGF21) FGF21-antibody conjugate in the crude conjugation mixture and from ∼80% to ∼85% in the final CVX-343 Drug Substance (DS), while maintaining the same overall process yield based on antibody scaffold input.

Comparison of demographics, treatment patterns, health care utilization, and costs among elderly patients with extensive-stage small cell and metastatic non-small cell lung cancers.

BACKGROUND: Limited data exist regarding real-world treatment patterns, resource utilization, and costs of extensive-stage small cell lung cancer (esSCLC) among elderly patients in the United States. While abundant data are available on treatment patterns in metastatic non-small cell lung cancer (mNSCLC), to our knowledge no data exist comparing costs and resource use between patients with esSCLC or mNSCLC. METHODS: We retrospectively analyzed administrative claims data (2000-2008) of patients aged ≥65 years from the linked Surveillance, Epidemiology and End Results (SEER)-Medicare database. Patients were selected on the basis of having newly diagnosed esSCLC (n=5,855) or mNSCLC (n=24,090) during 1/1/2000-12/31/2005, and were required to have received cancer-directed therapy. Survival and other measures were compared between esSCLC and mNSCLC patients using Kaplan-Meier log-rank and univariate chi-square and t-tests. Study measures were followed from first diagnosis date of either esSCLC or mNSCLC until the earlier of death or end of the database. RESULTS: Survival between the cohorts did not differ significantly: mean of 10.4 months for esSCLC patients versus 11.1 months for mNSCLC; median survival was 7.4 months versus 5.9 months. A higher percentage of mNSCLC patients (vs. esSCLC) received radiation therapy (75.6% vs. 65.4%; P < 0.001) and surgery (13.6% vs. 7.8%; P < 0.001) during the metastatic disease period. Conversely, a higher percentage of esSCLC patients than mNSCLC patients received chemotherapy (85.5% vs. 60.3%; P < 0.001), red blood-cell transfusion (20.7% vs. 10.9%; P < 0.001), platelet transfusion (5.6% vs. 1.8%; P < 0.001), and growth-factor support (59.0% vs. 39.5%; P < 0.001). esSCLC patients incurred higher lifetime disease-related costs ($44,167 vs. $37,932; P < 0.001) and all-cause costs ($70,549 vs. $67,176; P < 0.001) than mNSCLC patients. CONCLUSIONS: Lifetime total and disease-related costs per patient were high. Increased use of chemotherapy, supportive care therapies (including growth factors), and disease-related hospitalizations were observed in esSCLC patients as compared with mNSCLC patients. Disease-related and all-cause costs for esSCLC also exceeded those of mNSCLC, except for hospice and skilled nursing services. Survival and per-patient costs for both groups underscore the unmet medical need for more effective therapies in patients with esSCLC or mNSCLC.

Lunasin sensitivity in non-small cell lung cancer cells is linked to suppression of integrin signaling and changes in histone acetylation.

Lunasin is a plant derived bioactive peptide with both cancer chemopreventive and therapeutic activity. We recently showed lunasin inhibits non-small cell lung cancer (NSCLC) cell proliferation in a cell-line-specific manner. We now compared the effects of lunasin treatment of lunasin-sensitive (H661) and lunasin-insensitive (H1299) NSCLC cells with respect to lunasin uptake, histone acetylation and integrin signaling. Both cell lines exhibited changes in histone acetylation, with H661 cells showing a unique increase in H4K16 acetylation. Proximity ligation assays demonstrated lunasin interacted with integrins containing αv, α5, ß1 and ß3 subunits to a larger extent in the H661 compared to H1299 cells. Moreover, lunasin specifically disrupted the interaction of ß1 and ß3 subunits with the downstream signaling components phosphorylated Focal Adhesion Kinase (pFAK), Kindlin and Intergrin Linked Kinase in H661 cells. Immunoblot analyses demonstrated lunasin treatment of H661 resulted in reduced levels of pFAK, phosphorylated Akt and phosphorylated ERK1/2 whereas no changes were observed in H1299 cells. Silencing of αv expression in H661 cells confirmed signaling through integrins containing αv is essential for proliferation. Moreover, lunasin was unable to further inhibit proliferation in αv-silenced H661 cells. This indicates antagonism of integrin signaling via αv-containing integrins is an important component of lunasin's mechanism of action.

The Interconnectedness of Euglycemic Diabetic Ketoacidosis With Concomitant Thyroid Storm: A Case Report.

Sodium-glucose transport protein 2 inhibitors (SGLT2i) are becoming commonplace in many chronic diseases: type 2 diabetes mellitus, heart failure, and chronic kidney disease. We present the case of a 65-year-old male with a history of type 2 diabetes who had been on an SGLT2i for over 12 months and was found to have euglycemic diabetic ketoacidosis (eDKA) occurring concurrently with a thyroid storm. This case report illustrates a unique scenario of two endocrine emergencies occurring simultaneously.

Real-World Treatment Patterns and Clinical Outcomes Among Patients With Advanced Renal Cell Carcinoma.

BACKGROUND: Nearly 30% of new renal cell carcinoma (RCC) cases are diagnosed at an advanced or metastatic stage. Recent approvals of immunotherapies (IO) have significantly impacted patient care, but real-world outcomes of these treatments have not been widely evaluated. METHODS: Eligible physicians abstracted demographic and clinical data from patient medical records for patients with advanced clear and non-clear cell RCC (aRCC) who initiated treatment between January 1, 2018, and December 31, 2020. Overall survival (OS) and progression-free survival (PFS) were estimated by the Kaplan-Meier method. A multivariate Cox regression model was developed to assess the impact of treatment category on clinical outcomes while controlling for International Metastatic RCC Database Consortium (IMDC) risk category, histology, and other patient characteristics. RESULTS: A total of 498 patients were included (201 from US, 62 from Canada, 58 from UK, 59 from France, 58 from Germany, 60 from Spain). Of these, 250 received tyrosine kinase inhibitor (TKI) monotherapy, 197 received immunotherapy (IO) combination (119 IO+TKI, 78 IO+IO), and 32 received IO monotherapy as first-line treatment for aRCC; 19 patients received various other regimens. 16% of patients had a favorable IMDC risk score. Based on results of multivariable Cox regression, PFS (hazard ratio [HR] [95% confidence interval (CI)]: 0.50 [0.36-0.72]) (P < .001) and time to next treatment (TTNT) were significantly longer (HR [95% CI]: 0.54 [0.39-0.73]) (P < .001) for patients treated with IO combination versus TKI monotherapy. IO combination had a numerically reduced, but statistically insignificant, risk of death versus TKI monotherapy (HR: 0.66; P = .114). IO+TKI combination was associated with significantly longer PFS and reduced risk of progression (HR: 0.52; P = .04) versus IO+IO combination; similar results were observed for TTNT (HR: 0.57; P = .03). CONCLUSION: Our evaluation of real-world treatment outcomes in aRCC revealed that IO + TKI combination is associated with improved PFS and prolonged TTNT compared with TKI monotherapy and IO+IO combination.

Management of ADHD in children across Europe: patient demographics, physician characteristics and treatment patterns.

This study was a retrospective chart review performed to examine and describe physician practice patterns in managing attention deficit/hyperactivity disorder (ADHD) across Europe. Physicians treating ADHD in the UK, France, Germany, Italy, the Netherlands and Spain were recruited. Each physician abstracted medical records of five patients (aged 6-17 years at time of review) with a documented diagnosis of ADHD made between January 2004 and June 2007. Data provided by the physician via the abstraction included (a) physician characteristics, (b) patient characteristics, (c) ADHD diagnosis and (d) ADHD outcomes (adherence, symptom control and satisfaction). A total of 779 patients met study inclusion criteria. In the overall population, patients' mean (SD) age at time of diagnosis was 8.9 (2.6) years. The predominant treatment choice was long-acting methylphenidate, which was prescribed to more than 56 % of patients. According to physicians, only 30.8 % of patients showed 'complete symptom control' on current treatment and only 31.8 % of physicians reported being 'very satisfied' with their patients' current treatment. Physicians' assessments of complete symptom control and physician satisfaction with treatment were low, indicating unmet needs with current ADHD management in Europe.

Real-world effectiveness of lenvatinib monotherapy in previously treated unresectable hepatocellular carcinoma in US clinical practice.

BACKGROUND: Lenvatinib monotherapy was approved in the United States for first-line treatment of patients with unresectable hepatocellular carcinoma (uHCC) in 2018. This study assessed real-world treatment patterns and outcomes of lenvatinib beyond first-line systemic treatment in the United States. METHODS: A retrospective study was conducted among US adults (≥18 years) with uHCC. Eligible patients initiated lenvatinib monotherapy as second- or later-line systemic therapy (2L-plus) from August 2018 to September 2019. Clinical outcomes included physician-reported best response, progression-free survival (PFS), and overall survival (OS). RESULTS: Of 164 patients who received lenvatinib in 2L-plus, most (n = 133; 81.1%) received lenvatinib in 2 L. There were 109 patients (66.4%) who initiated lenvatinib after immunotherapy. At lenvatinib initiation, only 31.1% of patients had Child-Pugh class A, while half (49.4%) had Child-Pugh class B. Most patients had Barcelona Clinic Liver Cancer stage B (23.8%) or C (38.4%) uHCC. Median duration of lenvatinib treatment was 6.9 months, with 42.7% of patients still on treatment at the end of follow-up. Physician-reported best response was complete and partial response for 8.5% and 44.5% of patients, respectively. PFS and OS rate estimates from lenvatinib initiation at 12 months were 51.7% and 57.8%, respectively. Among patients treated after immunotherapy, complete and partial responses were 10.1% and 43.1%, respectively, and PFS and OS estimates from lenvatinib initiation at 12 months were 52.8% and 60.0%, respectively. CONCLUSION: This retrospective study suggests clinical effectiveness of lenvatinib monotherapy in a real-world setting among previously treated patients with uHCC, including among those previously treated with immunotherapy.

Early Real-World Treatment Patterns and Clinical Outcomes in Patients with Metastatic Breast Cancer Treated with Eribulin After Prior Immuno-Oncology or Antibody-Drug Conjugate Therapy.

Introduction: Eribulin was approved by the FDA in 2010 for the treatment of metastatic breast cancer (MBC) in the United States (US). More recently, several immuno-oncology (IO) and antibody-drug conjugate (ADC) regimens have been approved for MBC. We assessed the treatment patterns and clinical outcomes in MBC patients treated with eribulin following treatment with an IO or ADC in US clinical practice. Materials and Methods: In a retrospective patient medical chart review study, patients with MBC, aged ≥18 years, who initiated eribulin therapy between March 1, 2019, and September 30, 2020, treated with either prior IO or ADC in the metastatic setting were included. Patient demographics, treatment characteristics, and clinical outcomes were analyzed descriptively. Real-world progression-free survival (rwPFS) and overall survival (OS) were estimated using Kaplan-Meier analyses. Results: In the study population (N=143), median age at eribulin initiation was 62 years; 64% were Caucasian, and 67% had triple-negative MBC (TNBC). Eribulin therapy was used in the second to fifth line of therapy in the metastatic setting; median treatment duration was 7.2 months. The overall response rate for eribulin was 59.4%. Median rwPFS and OS from eribulin initiation were 21.4 months (95% CI, 12.9-not estimable [NE]) and 24.2 months (95% CI, 17.5-NE), respectively. In patients with TNBC, median rwPFS and OS from eribulin initiation were 12.0 months (95% CI, 8.8-NE) and 18.3 months (95% CI, 14.9-NE), respectively. Conclusion: These real-world data provide evidence for the clinical effectiveness outcomes of eribulin treatment among MBC patients previously treated with an IO or ADC.

Improved Survival Outcomes in Patients With MET-Dysregulated Advanced NSCLC Treated With MET Inhibitors: Results of a Multinational Retrospective Chart Review.

BACKGROUND: We evaluated the disease and patient characteristics, treatment, and MET testing patterns, predictive biomarkers and survival outcomes in patients with MET-dysregulated metastatic non-small-cell lung cancer (NSCLC) in a real-world setting. PATIENTS AND METHODS: This was a multinational, retrospective, noninterventional chart review study. Data from medical records of patients with advanced/metastatic EGFR wild-type, MET-dysregulated NSCLC (December 2017-September 2018) were abstracted into electronic data collection forms. RESULTS: Overall, 211 patient charts were included in this analysis; 157 patients had MET exon 14 skipping mutations (METex14; with or without concomitant MET amplification) and 54 had MET amplification only. All patients were tested for METex14, whereas MET amplification was evaluated in 168 patients. No overlap was reported between MET dysregulation and ALK, ROS1 or RET rearrangements, or HER2 exon 20 insertions. Overall, 56 of 211 patients (26.5%) received MET inhibitor (METi) therapy in any treatment-line setting (31.2% in the METex14 cohort; 13% in the MET-amplified only cohort). In the METex14 cohort, median OS in patients receiving METi was 25.4 months versus 10.7 months in patients who did not (HR [95% CI]: 0.532 [0.340-0.832]; P = .0055). In the MET-amplified only cohort, median OS was 20.6 months in patients treated with METi compared with 7.6 months in those without METi (HR [95% CI]: 0.388 [0.152-0.991]; P = .0479). CONCLUSIONS: MET alterations in NSCLC typically occur in the absence of other oncogenic driver mutations and are associated with poor survival outcomes. Notably, METi therapies are associated with improved survival outcomes in patients with MET-dysregulated NSCLC.
