REAL-WORLD IMPACT OF GOLD COMPLIANT COPD MAINTENANCE THERAPY ON EXACERBATIONS AND TREATMENT PATTERNS

BackgroundAvelumab, a PD-L1 immune checkpoint inhibitor (ICI), was recently approved as first-line (1L) maintenance therapy for locally advanced/unresectable or metastatic urothelial carcinoma (aUC) after disease control with platinum-based chemotherapy.1 Given the evolving treatment landscape, the study aim was to gain real-world insights into clinical decision-making among oncologists for patients with aUC.MethodsIn March 2021, a cross-sectional web-based survey was administered to a sample of US oncologists treating patients with aUC. Oncologists' demographics, practice characteristics, and treatment patterns were obtained; descriptive statistics were used.ResultsThe study included 151 medical oncologists, who reported that 54% and 31% of their patients, on average, would be classified as cisplatin or carboplatin eligible for their 1L treatment, respectively. Approximately 78% of oncologists (n=118) considered using ICI maintenance in ≥40% of their patients following disease control with platinum chemotherapy and were categorized as the “high-consideration” group, for further exploratory analysis; the rest (22%) were in the low-consideration group (See table 1). Approximately, 31% and 27% of oncologists in the high- and low-consideration groups reported administering ICI maintenance with a 2–3-week gap after chemotherapy, while 45% and 46% reported administering it with a 4–6-week gap after chemotherapy, respectively.ConclusionsSurveyed oncologists reported that 85% of patients with aUC in US may be eligible for platinum-based chemotherapy. Further, 78% of the surveyed oncologists would consider 1L ICI maintenance therapy after disease control with platinum-based chemotherapy for over 40% of their patients. Future studies are warranted to evaluate real-world treatment patterns, barriers, and utilization of ICI maintenance therapy as the new 1L standard of care.AcknowledgementsThe authors would like to acknowledge all physicians at who participated and completed the survey for the study.ReferencePowles T, et al.

e18042 Background: The clinical utility of maintenance therapy (MT) for patients with platinum-sensitive recurrent ovarian cancer (PSROC) has been validated in several clinical trials. We assessed real world treatment patterns using a US nationwide electronic health record database. Methods: A retrospective study of patients with PSROC between March 2017 and July 2019 was conducted using the Flatiron Health database. This longitudinal, demographically and geographically diverse de-identified database covers > 2.2 million oncology patients in > 280 cancer clinics. Patients were excluded if second or third line (2L or 3L) platinum-based chemotherapy (PBT) regimens included less than four or more than eight cycles of platinum. Information regarding somatic or germline BRCA mutations and homologous recombination deficiency (HRD) were obtained. Results: 2292 patients with PSROC were identified (had 2L or 3L treatment); 1214 of these received PBT at recurrence; 610 completed the PBT for recurrence on or after March 2017; 351 received 4–8 cycles of PBT; 225 patients had ≥2 months of active surveillance or were receiving MT of PARPi or bevacizumab (B) and were included in this analysis. 183 patients (80%) had BRCA testing and 14 patients (6%) had HRD testing. 46 (20%) had a germline or somatic BRCA mutations (t BRCA), 134 (59%) had a wildtype wt BRCA gene, and 48 (21%) were unknown. Of patients with tBRCA, 63% received a PARP inhibitor (PARPi), 17% received B, 20% received active surveillance. Of patients with wt BRCA, 40% received a PARPi, 24% received B, and 37% received active surveillance. Olaparib was the most commonly used PARPi among tBRCA patients (26%), while niraparib was most commonly used among wt BRCA patients (21%). MT was more common in younger patients, those with a better performance status and with a BRCA mutation. MT use trend increased by 21% during the study period. As PARPi use increased, the use of active surveillance as a post-platinum regimen decreased during the later time periods (Table). Conclusions: In this real world population, the majority of patients with PSROC are receiving maintenance therapy. While genetic testing is improving, universal testing of all patients with ovarian cancer remains the goal. The results provide insight into the shifting treatment patterns for patients with ovarian cancer. [Table: see text]

Background: In patients with newly-diagnosed multiple myeloma (NDMM) who receive frontline autologous stem cell transplantation (ASCT), maintenance therapy (MT) following ASCT has been shown to delay disease progression and death. Current National Comprehensive Cancer Network (NCCN) guidelines also recommend MT for patients with MM, including the use of lenalidomide, bortezomib-based regimens, or ixazomib. However, there is limited evidence on the use and outcomes associated with MT in contemporary real-world patients. The present study assessed MT treatment patterns and clinical outcomes in a real-world US cohort of patients with NDMM following ASCT. Methods: This retrospective, observational cohort study included NDMM patients initially diagnosed from 2011-2018 who received frontline ASCT. Patients were selected from the US Flatiron Health (FH) deidentified electronic health record (EHR)-derived database, which includes longitudinal patient-level data from over 265 community-based and academic cancer clinics across the US. To ensure capture of post-ASCT consolidation and MT, the study sample was restricted to patients who resumed contact within the FH network within 60 days following ASCT. Patients were excluded if they received treatment within the context of a clinical trial or had a second transplant within 180 days of their initial ASCT. Patients were classified as receiving MT if (during the 180-day post-transplant period) they initiated treatment with an NCCN-recommended MT regimen or continued to receive a subset of the antimyeloma agents used as induction regimen following ASCT and consolidation (if any). Key measures included baseline demographic and clinical characteristics, antimyeloma treatments (frontline induction, consolidation, and MT, if any), and clinical outcomes (time to next myeloma treatment [TTNT] and overall survival [OS]). Treatment duration and clinical outcomes were analyzed using Kaplan-Meier estimators and Cox regression to account for right-censoring. For TTNT and OS, follow-up began on the earlier of the ASCT date + 90 days or start of MT and continued through the dataset cut-off date (May 30, 2020) or loss to follow-up; TTNT and OS were estimated for patients receiving lenalidomide maintenance [R-MT], bortezomib maintenance [V-MT], or no MT, but was not estimated for other MT regimens due to sample size considerations. Results: 528 NDMM patients (median age 61 years, interquartile range [IQR]: 55, 68; 45.3% female) underwent ASCT and met study inclusion criteria. The most common induction regimens were bortezomib-lenalidomide-dexamethasone (VRd; 60.0%), lenalidomide-dexamethasone (Rd; 16.3%), and cyclophosphamide-bortezomib-dexamethasone (CyBorD; 10.2%). Following ASCT, 7.2% of patients received consolidation therapy and 74.2% received MT (lenalidomide monotherapy [R-MT]: 58.7%; bortezomib monotherapy [V-MT]: 7.6%; other MT: 7.8%). Median duration of MT was 18.0 months (IQR: 8.7, 29.1), and was similar for R-MT and V-MT (median 18.9 and 18.6 months, respectively). MT use increased from 69.3% to 79.0% from 2011-2013 to 2017-2018 (P=0.04); in addition, patients were more likely to have received VRd as induction across different MT (Table 1). R-MT and V-MT were both associated with longer TTNT relative to no MT (unadjusted hazard ratios [HRs]: 0.29 [95% CI: 0.22, 0.38] and 0.39 [95% CI: 0.25, 0.61], respectively) (Figure 1A). Improvements in OS were marginally significant with R-MT (HR: 0.58 [95% CI: 0.33, 1.00]) and nonsignificant with V-MT (HR: 0.86 [95% CI: 0.35, 2.11]) relative to no MT (Figure 1B); however, the OS estimates are characterized by low precision due to the relatively small number of events observed. Limitations included lack of documentation of reasons for treatment in the FH database, and use of consolidation and MT were inferred from observed treatment patterns; therefore, misclassification of MT was possible. Conclusions: This analysis demonstrates that MT use following ASCT has increased in routine clinical practice in the US since 2011-2013, with R-MT being the most common regimen followed by V-MT. However, a substantial proportion of patients did not receive MT. MT use in real-world settings was associated with longer TTNT and a trend toward longer OS. Exploration of additional maintenance regimens to improve clinical outcomes is warranted in this patient population.
