Objectives: Recent advances have created options for first-line (1L) treatment of advanced/metastatic non-small cell lung cancer (aNSCLC). The study objectives were to describe the utilization of 3 classes of 1L treatment-chemotherapy (CT), immunotherapy (IO), and chemoimmunotherapy (IO+CT)-and the total, third-party payer, direct health care costs., Study Design: Retrospective, administrative claims database analysis of patients with aNSCLC who initiated 1L treatment between January 1, 2017, and May 31, 2019, with IO, CT, or IO+CT., Methods: Microcosting enumerated health care resource utilization, including antineoplastic drug costs, using standardized costs. Generalized linear models estimated per-patient per-month (PPPM) costs during 1L treatment, and adjusted cost differences in 1L among treatment cohorts were calculated using recycled predictions., Results: A total of 1317 IO-, 5315 CT-, and 1522 IO+CT-treated patients were identified. Utilization of CT declined from 72.3% to 47.6% between 2017 and 2019, replaced by use of IO+CT, which increased from 1.8% to 29.8%. Total PPPM costs in 1L were highest with IO+CT at $32,436, compared with $19,000 and $17,763 in the CT and IO cohorts, respectively. Adjusted analyses showed that PPPM costs were $13,933 (95% CI, $11,760-$16,105) higher in the IO+CT vs IO cohort (P < .001) and IO costs were $1024 (95% CI, $67-$1980) lower than CT (P = .04)., Conclusions: IO+CT accounts for almost one-third of 1L aNSCLC treatment modalities, coinciding with a reduction in treatment with CT. Costs for patients treated with IO were lower than those for patients treated with both IO+CT and CT alone, driven primarily by antineoplastic drug and associated medical costs.

Background: Treatment for recurrent or advanced/metastatic non-small cell lung cancer (aNSCLC) has advanced in the past 5 years with immunotherapy (IO). This study sought to describe first-line (1L) aNSCLC treatment patterns and clinical outcomes., Methods: In this retrospective, multisite cohort study, community oncologists reported data for randomly selected stage IIIB/IV, EGFR-/ALK wild-type aNSCLC patients who initiated 1L systemic therapy from 01/01/2016 to 12/31/2019. Follow-up was through November 2020. Demographics, clinical characteristics, treatment patterns, disease response, progression, and death/last follow-up date were described. Overall response rate (ORR) was calculated using tumor measurements applying RECIST v1.1 guidelines. Progression-free survival (PFS) and overall survival (OS) were calculated from 1L initiation by Kaplan-Meier method., Results: 497 patients from 46 sites were included. The most common 1L regimens (%) were platinum-doublet chemotherapy plus IO (PDC+IO) (40.6%), PDC (29.4%), IO monotherapy (20.7%), and PDC+bevacizumab (6.2%). From 2016 to 2019, 1L PDC declined from 63% to 10%, whereas 1L PDC+IO increased from 14% to 58%. The ORRs were 64.9%, 32.9%, 60.2%, and 61.3% for 1L PDC+IO, PDC, IO monotherapy, and PDC+bevacizumab, respectively. Median 1L PFS/OS (months) was 15.6/26.5, 5.3/13.7, 17.8/not reached, 10.8/18.6, respectively, for PDC+IO, PDC, IO monotherapy, and PDC+bevacizumab. Among patients who received only 1L treatment (n = 299), 41.5% had no further therapy and were deceased., Conclusions: Although the 1L treatment paradigm has recently shifted to IO-based regimens, 41.5% did not survive past 1L. Median 1L PFS did not exceed 1.5 years and median OS remained limited across all 1L treatment groups, illustrating continued unmet aNSCLC therapeutic needs., Competing Interests: Declaration of Competing Interest LB receives consulting fees from Jannsen, Novartis, Boehringer Ingelheim, BMS, Merk, Regeneron, Genentech, Daichi, Sankyo, Bluprint, Takeda, Astra Zeneca, Bayer, Beyondsping, G1, Therapeutics, and Abbvie, and participates on an advisory board with Neuvogen and ORIC, owns stock or stock options; JK is an employee of Cardinal Health; BC is an employee of Novartis, receives salary, and is a stockholder of Novartis; NC is an employee of Novartis and is a stockholder of Novartis Pharmaceuticals; BF is an employee and a stockholder of Cardinal Health., (Copyright © 2022.

Background: The ErbB family blocker, afatinib, is approved for patients with squamous cell carcinoma (SqCC) of the lung following platinum-doublet chemotherapy but has not been explored following immunochemotherapy. Here, we assessed the characteristics and outcomes of patients with SqCC of the lung who received second-line afatinib or chemotherapy after first-line pembrolizumab plus chemotherapy in a "real-world" setting., Methods: In this retrospective, multisite cohort study, community oncologists identified eligible patients and extracted data from electronic health records. Primary outcome measures were patient demographics and clinical characteristics, time on treatment, and incidence of severe immune-related adverse events (irAEs)., Results: Two hundred patients were included: 99 received second-line afatinib and 101 received second-line chemotherapy. Median age was 68 and 66 years, respectively; 35% and 3% of patients had mixed histology tumors, and 39% and 5% of tumors were epidermal growth factor receptor (EGFR) mutation-positive (EGFRm + ). Median time on treatment was 7.3 months with afatinib (mixed histology/SqCC tumors: 8.1/5.8 months; EGFRm + /EGFRm - tumors: 7.4/5.9 months) and 4.2 months with chemotherapy. Grade 3/4 irAEs were observed in 6 patients in the afatinib cohort (all had a prior grade 3/4 irAE during first-line therapy) and no patients in the chemotherapy cohort. The most common adverse drug reactions with afatinib were diarrhea (26%), rash (6%), stomatitis, fatigue, and nausea (5% each)., Conclusion: Encouraging time on treatment, and absence of newly diagnosed irAEs, indicate that afatinib is a treatment option following immunochemotherapy in patients with SqCC of the lung, and is currently the only approved oral agent in this setting., (Copyright © 2021 The Authors.

Aim: To estimate the real-world incidence and timing of radiation pneumonitis following chemoradiotherapy for Stage III non-small-cell lung cancer and compare costs between patients with and without radiation pneumonitis. Methods: Retrospective analysis using the Symphony Health Integrated Dataverse. Results: Pneumonitis incidence was 12.4% with a 177-day mean time to onset. Patients with versus without pneumonitis were more frequently admitted to the hospital (33.8 vs 19.2%, p < 0.0001) and seen in the emergency room (51.9 vs 35.8%, p < 0.0001) and had higher mean total healthcare costs (US$4251 vs US$3969 per-patient per-month; p = 0.0163). Conclusion: Although pneumonitis significantly increased healthcare resource utilization and costs in chemoradiotherapy-treated Stage III non-small-cell lung cancer, the per-patient per-month differential was <10%. Such financial assessments are critical for cost-benefit analysis.

Does the rapid integration of both targeted and immuno-oncology drugs into treatment guidelines across solid tumors and hematologic malignancies herald the beginning of the end of chemotherapy as a foundational element in systemic cancer treatment? We respond to similar assertions posited after the 2018 American Society of Clinical Oncology Annual Meeting with an analysis of past, current, and future treatment of breast cancer-a tumor central to the evolution of modern cancer treatment principles. Our conclusions assert that reports of the demise of chemotherapy are greatly exaggerated and, as chemotherapy is likely to remain foundational for years to come, research is warranted to improve its patient-centricity.

This study assesses resource utilization and total direct medical cost among patients in the United States starting systemic antineoplastic therapy (ST) pre- and postapproval of immuno-oncology (IO) agents for advanced non-small cell lung cancer. Adults diagnosed with lung cancer initiating first-line ST within 6 months of diagnosis during either the pre- (March 2013-March 2014) or post-IO (March 2015-December 2016) approval period were identified in a US-based multipayer administrative claims database. Excluded were patients with small cell lung cancer, secondary malignancies, less than 1 month follow-up, and those in clinical trials. Total cost (TC) was calculated from the date of initiation of treatment until the last follow-up. Propensity score matching was adjusted for differences in patient cohorts, including follow-up time. Binary multiple logistic regression assessed predictors of high TC (above mean) pre- and post IO. Mean TC per patient was higher pre-IO versus post IO in both unmatched ($165,548 vs $95,715) and matched analyses($129,977 vs $113,177). Hospitalization and emergency department (ED) visit rates were higher pre-IO versus postapproval. Predictors of high TC pre-IO included use of first-line combination therapy, radiation, targeted therapy, maintenance therapy, biomarker testing, more comorbidities, longer follow-up, first-line hospitalization, first-line cost above mean, and age 65 years and older. In the post-IO period, additional predictors of higher TC included use of IO, having mild liver disease or hemiplegia, and longer time to ST initiation. Early data show lower ED visit and hospitalization rates and associated lower TC in the post-IO era.
