Real-world treatment patterns and outcomes of patients with advanced melanoma treated with nivolumab plus relatlimab

Abstract The use of programmed death-1 (PD-1) inhibitors has been a pivotal advancement in treating advanced melanoma, yet their efficacy is limited. The approval of relatlimab (RELA), a lymphocyte activation gene 3 protein (LAG-3) antibody, in combination with nivolumab (NIVO), a PD-1 inhibitor, marked a significant stride toward enhancing treatment efficacy for metastatic and unresectable stage 3 and 4 melanoma. This combination has been shown to synergistically improve antitumor activity and effector T-cell activity in the tumor microenvironment, despite limited data on real-world outcomes. Our retrospective review at a tertiary cancer center of patients with stage 3 and 4 melanoma treated with NIVO-RELA revealed an overall response rate (ORR) of 39%, with notable improvements in median PFS and ORR, especially in first-line treated patients. Our study highlights the superior efficacy of NIVO-RELA over previous reports, demonstrating its significant potential in the treatment landscape of advanced melanoma.

Characteristics and real-world medication persistence of people living with HIV treated with DTG/3TC or BIC/FTC/TAF: a hospital claims database study in Japan

BackgroundAs the life expectancy of people living with human immunodeficiency virus (HIV) (PLWH) has improved, chronic disease burden and polypharmacy have increased in PLWH. Simplification of the antiretroviral therapy (ART) regimen for PLWH has become crucial. The real-world treatment patterns and medication persistence of the 2-drug single-tablet regimen (STR), dolutegravir/lamivudine (DTG/3TC), compared to bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) prescribed were investigated.MethodsThis retrospective, database study extracted data from a hospital-based medical claims database in Japan. The changes in ART distributions by year during the identification period between January 1, 2018 and December 31, 2021 were observed. Patients with disease record of HIV-1 infection and prescribed DTG/3TC or BIC/FTC/TAF as the first prescription of STR during the identification period were divided into two cohorts; DTG/3TC cohort and BIC/FTC/TAF cohort, respectively. Patient without medication records more than 3 months and no future data more than 6 months were excluded. Patients’ characteristics were compared between the DTG/3TC cohort and the BIC/FTC/TAF cohort by Mantel–Haenszel test to adjust for age. Medication persistence was compared between the two cohorts by evaluating the continuation rates using Kaplan–Meier methods, using the log-rank test to assess the difference between the Kaplan–Meier curves. The median time-to-first prescription was compared between the two cohorts by Kaplan–Meier methods.ResultsPrescriptions of DTG/3TC and BIC/FTC/TAF increased steadily from 2019 to 2021 after the release year of each STR. There was no significant difference in the time-to-first prescription (p = 0.3). A total of 959 patients were included, with 120 patients and 839 patients on DTG/3TC and BIC/FTC/TAF, respectively. The proportion of dyslipidemia at baseline was significantly higher in the DTG/3TC cohort than in the BIC/FTC/TAF cohort after adjusting for mean age (p = 0.002). There was no significant difference in medication persistence between the two cohorts (p = 0.91).ConclusionThis study showed that DTG/3TC was likely to be selected for elderly patients and those with chronic disease in real-world clinical practice, which seems in accordance with the treatment strategy recommended by guidelines. Comparable medication persistence was observed with both regimens, aligning with findings from other countries. The 2-drug single-tablet regimen DTG/3TC may be an important ART regimen for PLWH with multiple morbidities and polypharmacy in an aging society. Due to the limitations of the database, further research to assess viral loads, emergence of resistance and adverse events will be encouraged.

Emapalumab Use in Patients With Rheumatologic Disease-Associated Hemophagocytic Lymphohistiocytosis in the United States: the REAL-HLH Study.

Rheumatologic disease-associated hemophagocytic lymphohistiocytosis (HLH), a rare, life-threatening, systemic hyperinflammatory syndrome, occurs as a complication of underlying rheumatologic disease. Real-world evidence is lacking on emapalumab, a fully human monoclonal antibody that neutralizes the proinflammatory cytokine interferon-gamma, approved for treating patients with primary HLH. REAL-HLH, a retrospective medical chart review study conducted across 33 US hospitals, assessed real-world treatment patterns and outcomes in patients with HLH treated with ≥1 dose of emapalumab between November 20, 2018, and October 31, 2021. Data are presented for the subset of patients with rheumatologic disease-associated HLH. Fifteen of 105 patients (14.3%) had rheumatologic disease-associated HLH. Of these, 9 (60.0%) had systemic juvenile idiopathic arthritis, and 1 (6.7%) had adult-onset Still's disease. Median (range) age at HLH diagnosis was 5 (0.9-39) years. Most (9/15; 60.0%) patients initiated emapalumab in an intensive care unit. Emapalumab was most frequently initiated for treating refractory or recurrent (10/15; 66.7%) disease. Most patients received HLH-related therapies prior to (10/15; 66.7%) and concurrently (15/15; 100.0%) with emapalumab. Emapalumab-containing regimens stabilized or achieved physician-determined normalization of most laboratory parameters including fibrinogen (11/13; 84.6%), chemokine ligand 9 (7/8; 87.5%), and absolute neutrophil count (6/10; 60%), and reduced glucocorticoid dose by 80%. Overall survival and 12-month survival probability from emapalumab initiation were 86.7%. Emapalumab-containing regimens stabilized or normalized most key laboratory parameters, reduced glucocorticoid dose, and were associated with low disease-related mortality, thereby demonstrating potential benefits in patients with rheumatologic disease-associated HLH.

Real-world treatment patterns, health care resource utilization, and costs in a US Medicare population with bronchiectasis.

Bronchiectasis carries a significant economic burden with high health care expenditures associated with frequent hospitalizations, physician visits, and treatments, including oral and intravenous antibiotics for repeated lung infections, airway-clearance therapy, and oxygen administration. Bronchiectasis exacerbations can contribute to this burden. To estimate US health care resource utilization (HCRU) and costs associated with bronchiectasis and with bronchiectasis exacerbations. This retrospective study used the 100% Medicare Fee-for-Service database (January 2014 to December 2020) to compare HCRU and costs among patients with bronchiectasis with those of patients without bronchiectasis (controls). For patients with bronchiectasis, the index date was a randomly selected bronchiectasis claim after more than 1 year of disease history and, for controls, a claim closest to their matched bronchiectasis patient's index date. All patients had continuous enrollment for at least 12 months pre-index (baseline) and at least 12 months post-index. Primary outcomes were all-cause, respiratory-related, and bronchiectasis-related HCRU and health care costs, which were presented by the overall sample and by segmented patient cohorts based on the number of exacerbations during baseline (0, 1, or ≥2). 92,529 patients with bronchiectasis (mean [SD] age, 76.7 [8.8] years; 72.3% female) and 92,529 matched controls qualified for the study. Compared with controls, patients with bronchiectasis presented greater mean (SD) all-cause physician visits (15.4 [10.0] vs 13.2 [9.7]; P < 0.001) and respiratory-related physician visits (5.2 [4.3] vs 1.9 [3.1]), pulmonologist visits (1.9 [2.2] vs 0.3 [1.0]), hospitalizations (0.4 [0.9] vs 0.3 [0.8]), emergency department visits (0.33 [1.0] vs 0.26 [1.0]), and total health care costs ($10,224 [$23,263] vs $6,704 [$19,593]). Respiratory-related HCRU was also greater in patients with more baseline exacerbations, with total health care costs of $8,506, $10,365, and $14,790 for patients with 0, 1, and at least 2 exacerbations, respectively (P < 0.01). This real-world study demonstrates the high disease burden associated with bronchiectasis and with exacerbations, highlighting the need to improve management and reduce exacerbations.

Real-world treatment patterns, resource utilization and costs in biliary tract cancers in the USA.

Aim: To evaluate real-world treatment patterns, survival and healthcare-resource utilization in US patients with advanced biliary tract cancers (BTC) receiving systemic therapy.Patients & methods: This study used claims data from the Healthcare Integrated Research Database (HIRD®) linked to clinical data from the Cancer Care Quality Program (January 1, 2015-September 30, 2020).Results: Of 413 patients, 84.5% received gemcitabine-based first-line (1L) treatment, 46% received second-line treatment, and 16.5% received third-line (3L) treatment. All-cause mortality was 53% and approximately 70% of patients had ≥1 inpatient visit. The total mean per-patient-per-month all-cause costs were $19,589 for 1L and $33,534 for 3L treatment.Conclusion: Results showed poor survival, significant resource use and high costs as treatment line progresses for patients with advanced BTC.

Real-World Clinical Outcomes and Treatment Patterns Among Black and Non-Black Patients With Prostate Cancer Initiated on Apalutamide in a Urology Setting

Background: The use of androgen receptor signaling inhibitors, including apalutamide, in combination with androgen deprivation therapy is recommended for the treatment of metastatic castration-sensitive prostate cancer (mCSPC) and non-metastatic castration-resistant prostate cancer (nmCRPC). Objective: To describe real-world treatment patterns and clinical outcomes among patients with mCSPC or nmCRPC who initiated apalutamide in the United States. Methods: A retrospective cohort study of patients with mCSPC or nmCRPC who initiated apalutamide was conducted using electronic medical record data from US community-based urology practices (Feb. 1, 2017–April 1, 2022). Persistence with apalutamide was reported at 6-, 12-, and 18-months post treatment initiation. Clinical outcomes described up to 24 months after apalutamide initiation using Kaplan-Meier analyses included progression to castration resistance, castration resistance-free survival (CRFS), and metastasis-free survival (MFS). Outcomes were reported separately based on mCSPC or nmCRPC status and race (ie, Black or non-Black). Results: This study included 589 patients with mCSPC (mean age, 75.9 years) and 406 patients with nmCRPC (mean age, 78.8 years). Using a treatment gap of &gt;90 days, persistence with apalutamide at 12 months remained high for both the mCSPC (94.9%) and nmCRPC (92.7%) cohorts, and results were descriptively similar among Black and non-Black patients, and when a treatment gap of &gt;60 days was considered. In patients with mCSPC, overall progression to castration resistance rates at 12 and 24 months were 20.9% and 33.5%, and overall CRFS rates were 76.2% and 62.0%, respectively. In patients with nmCRPC, overall MFS rates at 12 and 24 months were 89.7% and 75.4%, respectively. Rates of these clinical outcomes were descriptively similar between Black and non-Black patients. Discussion: While clinical trials have demonstrated the efficacy and safety of apalutamide, there is limited real-world data describing treatment persistence and clinical outcomes among patients with mCSPC and nmCRPC who initiated apalutamide. Conclusions: In this real-world study of patients with mCSPC or nmCRPC initiated on apalutamide, treatment persistence was high and apalutamide demonstrated robust real-world effectiveness with respect to progression to castration resistance, CRFS, and MFS, overall and among Black and non-Black patients.
