Real-life use of ramucirumab in gastric cancer in Spain: the RAMIS study

Aims: To obtain real-world data on ramucirumab use and effectiveness for the treatment of advanced gastric cancer (AGC) or gastroesophageal junction adenocarcinoma (GEJ). Methods: Observational, retrospective study carried out in 20 Spanish hospitals, in patients who started ramucirumab treatment between December 2015 and December 2018. Descriptive analysis was conducted for patient characteristics, treatment patterns and effectiveness outcomes. Results: Three hundred seventeen patients were included (93.7% treated with ramucirumab-paclitaxel and 6.3% with ramucirumab); age 62.5 (11.3) years; 66.9% male. Median progression-free survival and overall survival were 3.9 months (95% CI: 3.4–4.3) and 7.4 (95% CI: 6.4–8.9) in combination regimen and 2.0 (1.1–2.8) and 4.3 (95% CI: 1.9–7.3) in monotherapy, respectively. Conclusion: The study findings were consistent with available real-world studies and randomized clinical trials.

8561 Background: Atezolizumab plus chemotherapy was the first CIT combination regimen approved for 1L treatment of ES-SCLC in 2019. This study investigated patient characteristics and treatment patterns for patients with ES-SCLC receiving this regimen in the real-world community oncology setting. Methods: This was a retrospective study including adult patients diagnosed with ES-SCLC between 01-Oct-2018 (after IMpower 133 publication in NEJM Sep-2018) and 31-Dec-2019, with follow-up through 31-March-2020 using The US Oncology Network electronic health records data. Descriptive analyses of patient characteristics and treatment patterns were conducted, with Kaplan-Meier (K-M) methods used to assess time to treatment discontinuation (TTD) and time to next treatment/death (TTNT). Results: Of the 408 patients included in this study, 267 (71.4%) received atezo+carboplatin+etoposide (Atezo+Chemo), 80 (21.4%) received carboplatin+etoposide (Chemo only) and the rest received other regimens. The Atezo+Chemo patients in the real-world cohort compared with the IMpower 133 trial (n = 201) were older (median age 68 vs. 64 years) and included fewer males (45% vs. 64%), fewer white race (73% vs. 81%), more patients with brain metastases at baseline (23% vs. 9%), and more patients with worse ECOG (2/3) performance-status score (24% vs. 0%). The median follow-up, TTD, and TTNT in months (mo) for the real-world cohort are presented in the table alongside the best comparable measures reported for the trial. Conclusions: Most patients in this real-world ES-SCLC cohort received the Atezo+Chemo regimen in the 1L setting. While the follow-up was much shorter and patients had worse baseline characteristics (age, brain metastases, ECOG) in the real-world setting compared to the IMpower 133 trial, the real-world median TTD in this descriptive analysis was found to be in line with the median duration of treatment in the trial. Further research with longer follow-up comparing the real-world effectiveness of the CIT and chemo regimens is needed.[Table: see text]

Liposomal Irinotecan

Background: Liposomal irinotecan (nal-IRI) plus 5-fluorouracil and leucovorin (5-FU/LV) was effective and well-tolerated in patients with metastatic pancreatic adenocarcinoma (mPAC) that progressed on gemcitabine-based therapy in the global NAPOLI-1 trial. Real-world data may further clarify the outcomes and safety profile of nal-IRI + 5-FU/LV in clinical practice. Methods: This retrospective analysis included patients with mPAC who received nal-IRI + 5-FU/LV following gemcitabine-based therapy under a Managed Access Program in Korea. Results: From January 2017 to April 2018, 86 patients across 10 institutions received nal-IRI + 5-FU/LV (median age, 61 years; 60% male; ECOG performance status, 0–1). A total of 35 (41%) and 51 (59%) patients had received less than two and two or more lines of chemotherapy before inclusion, respectively. At a median follow up of 6.4 months, median overall survival (OS) was 9.4 months (95% confidence interval [CI] 7.4–11.4) and median progression-free survival (PFS) was 3.5 months (95% CI 1.3–5.7). Six-month OS and PFS rates were 65.1% and 37.5%, respectively. Objective response and disease control rates were 10% and 55%, respectively. Most common grade 3–4 toxicities were neutropenia (37.2%), nausea (10.5%), vomiting (9.3%), anorexia (8.1%) and diarrhoea (4.7%). Conclusion: Real-life data for Korean patients indicate that, consistent with NAPOLI-1, nal-IRI + 5-FU/LV is effective and well-tolerated in patients with mPAC that progressed on gemcitabine-based therapy.

611 Background: Pazopanib (Pazo) became a standard of care in metastatic renal cell cancer (mRCC) patients (pts) based on 2 prospective trials, but “real life” data are slight. Methods: We retrospectively analyzed clinical outcomes in a large series of mRCC pts routinely treated with 1st line Pazo, among 39 Italian Centers. Descriptive statistics has been performed using Chi-Square and Pearson rank correlation test. Progression-free survival (PFS), overall survival (OS) and safety data are still under investigation. Results: 474 mRCC pts have been collected and divided in 4 age categories: 1) ≤50 yrs old (9.4%); 2) 51-64 yrs old (32.6%); 3) 65-74 yrs old (33.0%); 4) ≥75 yrs old (25.0%). According to Heng score, 25.6%, 48.4% and 10.4% pts had good, intermediate and poor prognosis, respectively, without correlations with age (p = 0.128). Clear cell was the most represented histology (87.3%), independently from age (p = 0.556). 84.6% pts underwent nephrectomy, mainly younger pts (p = 0.000). Pazo initial daily dose was 800 mg in 76.5% pts, 600 mg in 10.8% pts and 400 mg in 12.7% pts, with a significant dose reduction in elderly pts: Pazo 800 was administered in 86.7% of ≤50 yrs old pts and in 54.2% of ≥75 yrs old pts (p = 0.000). Complete (CR)/partial response (PR), stable and progressive disease have been recorded in 37%, 39.5% and 23.5% pts, respectively. Radiological response directly correlated either with age (CR/PR in 55.6% of ≤50 yrs old pts vs 28.8% of ≥75 yrs old pts; p = 0.009) and with Heng score (CR/PR in 47.1% of good prognosis pts vs 24.5% of poor prognosis pts; p = 0.002). Conclusions: “Real world” data showed that younger (≤50 yrs old) mRCC pts more frequently underwent nephrectomy, received Pazo 800 mg daily and obtained CR/PR, with respect to elderly pts (≥75 yrs old). CR/PR to Pazo is associated with good prognosis. PFS and OS will be provided.

In Hungary, the cost of lenalidomide-based therapy is covered only for relapsed multiple myeloma (MM) patients, therefore lenalidomide is typically used in the second-line either as part of a triplet with proteasome inhibitors or as a doublet. Lenalidomide-dexamethasone is a standard treatment approach for relapsed/refractory MM, and according to recent large randomized clinical trials (RCT, the standard arm of POLLUX, ASPIRE, TOURMALINE), the progression-free survival (PFS) is expected to be approximately 18 months. We surveyed ten Hungarian centers treating MM and collected data of 278 patients treated predominantly after 2016. The median age was 65 years, and patients were distributed roughly equally over the 3 international staging system groups, but patients with high risk cytogenetics were underrepresented. 15.8% of the patients reached complete response, 21.6% very good partial response, 40.6% partial response, 10.8% stable disease, and 2.5% progressed on treatment. The median PFS was unexpectedly long, 24 months, however only 9 months in those with high risk cytogenetics. We found interesting differences between centers regarding corticosteroid type (prednisolone, methylprednisolone or dexamethasone) and dosing, and also regarding the choice of anticoagulation, but the outcome of the various centers were not different. Although the higher equivalent steroid dose resulted in more complete responses, the median PFS of those having lower corticosteroid dose and methylprednisolone were not inferior compared to the ones with higher dose dexamethasone. On multivariate analysis high risk cytogenetics and the number of prior lines remained significant independent prognostic factors regarding PFS (p < 0.001 and p = 0.005). Our results show that in well-selected patients Lenalidomide-dexamethasone can be a very effective treatment with real-world results that may even outperform those reported in the recent RCTs. This real world information may be more valuable than outdated RCT data when treatment options are discussed with patients.

4025 Background: Gastric cancer (GC) is the second leading cause of cancer-related deaths in China. Trastuzumab (TRA) has been used to treat HER2+ metastatic gastric cancer (mGC) in China since 2012. However, real-world data on effectiveness and safety in Chinese patients are limited. Methods: This prospective, multicenter (85 hospitals), real-world noninterventional registry study evaluated the effectiveness and safety of TRA in five cohorts of Chinese GC patients with different HER2 statuses from April 2013 to June 2018. Effectiveness analysis was conducted in three cohorts: Cohort I (HER2+ mGC with TRA), Cohort II (HER2+ mGC untreated with TRA) and Cohort IV (HER2− mGC untreated with TRA). Safety outcomes of TRA-related adverse events (AEs) were analyzed in Cohort I. Results: Cohorts I, II and IV included 709 patients (174, 113 and 422, respectively; mean age 57.8 years; 72% male); 64.9% of patients were ECOG 0–1, 93.7% had a primary GC tumor and 42.3% were at stage T4. Progressive disease was the cause of death in 32.8%, 27.4% and 29.9% in Cohorts I, II and IV, respectively. Respective mean duration of follow-up was 422.5, 287.5 and 277.5 days. Median overall survival (OS) was 22.3, 17.2 and 17.4 months, respectively. After excluding patients who had surgery, the respective median OS was 19.9, 15.3, and 12.6 months. For the first-line treatment, the median OS in Cohort I was 22.1 months, and the median progression free survival (PFS) was 8.2, 6.9 and 6.2 months in Cohorts I, II and IV, respectively. Response rates (RR) for first-line treatment in Cohorts I, II and IV were 51.7%, 18.4% and 32.8%, respectively. After propensity score matching, OS, PFS and RR were all significantly better in Cohort I versus II (all P<0.05). The most common regimen, TRA+XELOX (capecitabine+oxaliplatin), was estimated to have the longest median OS at 34.6 months. Grade ≥3 AEs were reported in 33.9% (59/174) of patients in Cohort I; anemia was the most common AE (12.1%). Conclusions: TRA improved OS and PFS in Chinese HER2+ mGC patients compared with chemotherapy alone and was well tolerated and effective when combined with a range of other therapies in a real-world setting. Clinical trial information: NCT01839500.

Objective: To explore the clinical efficacy and safety of camrelizumab in the treatment of digestive system malignancies in the real world. Methods: A retrospective study was designed. A total of 34 patients with advanced gastrointestinal cancer who received camrelizumab treatment in the xx hospital from July 2019 to May 2020 were included. The follow-up endpoint was set for October 30, 2020. The primary endpoint was objective response rate (ORR) and safety. Secondary endpoint measures included progression-free survival (PFS), and overall survival (OS). Cox regression was used for the analysis of factors associated with PFS. Results: As the best response, only 5 patients achieved a partial response and 10 patients had disease progression, with an ORR of 14.31%. Compared with gastric cancer, the ORR of esophageal cancer (3.0% vs 0.0%) (P<0.05). The PFS was 4.5 months (2-10 months). OS ranged from 4 to 11 months, and median OS has not been reached. Multivariate Cox regression analysis showed that gastric cancer (HR=1.695, 95% CI:11.216–2.435, P<0.05) was associated with still shorter PFS, and camrelizumab combined with other drugs (HR=0.512, 95% CI: 0.095–0.737, P<0.01) was associated with PFS in patients. The most common AEs were anemia (41.2%, 14/34) in all grades 1 to 2. Grade 3 AEs occurred in 3 patients (2.9%), including 1 case of immune pneumonitis, 1 case of hemangioma, and 1 case of transaminase increased. Other adverse events included diarrhea, nausea, neutropenia, thrombocytopenia, reactive cutaneous capillary proliferation (RCCEP), fatigue, and hypothyroidism, all of which did not exceed 12%. Conclusion: Camrelizumab is effective and safe in the treatment of patients with digestive system malignancies, but the overall response rate is limited.

Abstract Background Safety and efficacy of immune checkpoint inhibitors in advanced gastric or gastroesophageal junction (GEJ) cancer could be demonstrated in predominantly Asian cohorts, whereas data in Western patients outside of clinical trials are vastly missing. Methods In this multi-institutional retrospective analysis conducted at nine oncologic centers in Austria, we tried to assess feasibility of checkpoint inhibitors in advanced gastric/GEJ cancer in a real-world Western cohort. Results In total, data from 50 patients with metastatic gastric/GEJ cancer who received nivolumab or pembrolizumab in a palliative setting between November 2015 and April 2020 have been evaluated. The median number of previous palliative therapy lines was two. The median progression-free survival (PFS) and overall survival (OS) were 2.1 (95% CI: 1.4–2.8) and 6.3 (95% CI: 3.3–9.3) months, respectively. There was no statistically significant difference in median OS according to microsatellite or PD-L1 status. However, a trend towards prolonged PFS and OS for the microsatellite instability high subgroup could be observed. Patients with an ECOG Performance Status (PS) ≥ 2 displayed a significantly worse outcome than those with an ECOG PS ≤ 1 (p = .03). Only one patient discontinued immunotherapy due to treatment-related toxicity. Conclusions Our results support feasibility of nivolumab and pembrolizumab in pre-treated patients with metastatic gastric and GEJ cancer in a Western real-world cohort. Further phase II/III studies are needed to confirm clinical efficacy.

Purpose: Treatment with CDK4/6 inhibitors and endocrine therapy (CDK4/6i + ET) is a standard for patients with advanced hormone receptor-positive, HER2-negative (HR + HER2-) breast cancer (BC). However, real-world data on the implementation of therapy usage, efficacy, and toxicity have not yet been reported. Methods: The PRAEGNANT registry was used to identify advanced HR + HER2- BC patients (n = 1136). The use of chemotherapy, ET, everolimus + ET, and CDK4/6i + ET was analyzed for first-line, second-line, and third-line therapy. Progression-free survival (PFS) and overall survival (OS) were also compared between patients treated with CDK4/6i + ET and ET monotherapy. Also toxicity was assessed. Results: CDK4/6i + ET use increased from 38.5% to 62.7% in the first 2 years after CDK4/6i treatment became available (November 2016). Chemotherapy and ET monotherapy use decreased from 2015 to 2018 from 42.2% to 27.2% and from 53% to 9.5%, respectively. In this early analysis no statistically significant differences were found comparing CDK4/6i + ET and ET monotherapy patients with regard to PFS and OS. Leukopenia was seen in 11.3% of patients under CDK4/6i + ET and 0.5% under ET monotherapy. Conclusions: In clinical practice, CDK4/6i + ET has been rapidly implemented. A group of patients with a more unfavorable prognosis was possibly treated in the real-world setting than in the reported randomized clinical trials. The available data suggest that longer follow-up times and a larger sample size are required in order to identify differences in survival outcomes. Studies should be supported that investigate whether chemotherapy can be avoided or delayed in this patient population by using CDK4/6i + ET.

Abstract Background Since the results of the ToGA trial were published, trastuzumab-based chemotherapy has been used as the standard first-line treatment for HER2-positive recurrent or primary metastatic gastric cancer (RPMGC). However, the real-world data has been rarely reported. Therefore, we investigated the outcomes of trastuzumab-based chemotherapy in a single center. Methods This study analyzed the real-world data of 47 patients with HER2-positive RPMGC treated with trastuzumab-based chemotherapy in a single institution. Results With the median follow-up duration of 18.8 months in survivors, the median overall survival (OS) and progression-free survival were 12.8 and 6.9 months, respectively, and the overall response rate was 64%. Eastern Cooperative Oncology Group performance status 2 and massive amount of ascites were independent poor prognostic factors for OS, while surgical resection before or after chemotherapy was associated with favorable OS, in multivariate analysis. In addition, 5 patients who underwent conversion surgery after chemotherapy demonstrated an encouraging median OS of 30.8 months, all with R0 resection. Conclusions Trastuzumab-based chemotherapy in patients with HER2-positive RPMGC in the real world demonstrated outcomes almost comparable to those of the ToGA trial. Moreover, conversion surgery can be actively considered in fit patients with a favorable response after trastuzumab-based chemotherapy.

Localization Accuracy

AbstractIn outdoor RF localization systems, particularly where line of sight can not be guaranteed or where multipath effects are severe, information about the terrain may improve the position estimate’s performance. Given the difficulties in obtaining real data, a ray-tracing fingerprint is a viable option. Nevertheless, although presenting good simulation results, the performance of systems trained with simulated features only suffer degradation when employed to process real-life data. This work intends to improve the localization accuracy when using ray-tracing fingerprints and a few field data obtained from an adverse environment where a large number of measurements is not an option. We employ a machine learning (ML) algorithm to explore the multipath information. We selected algorithms random forest and gradient boosting; both considered efficient tools in the literature. In a strict simulation scenario (simulated data for training, validating, and testing), we obtained the same good results found in the literature (error around 2 m). In a real-world system (simulated data for training, real data for validating and testing), both ML algorithms resulted in a mean positioning error around 100 ,m. We have also obtained experimental results for noisy (artificially added Gaussian noise) and mismatched (with a null subset of) features. From the simulations carried out in this work, our study revealed that enhancing the ML model with a few real-world data improves localization’s overall performance. From the machine ML algorithms employed herein, we also observed that, under noisy conditions, the random forest algorithm achieved a slightly better result than the gradient boosting algorithm. However, they achieved similar results in a mismatch experiment. This work’s practical implication is that multipath information, once rejected in old localization techniques, now represents a significant source of information whenever we have prior knowledge to train the ML algorithm.
