Retacrit®, Biosimilar of Epoetin Alfa, in Chemotherapy-Induced Anemia in Routine Practice: Impact of Iron Supplementation.

INTRODUCTION: The aim of the study was to evaluate in real-life conditions the effectiveness and safety of a biosimilar of epoetin alfa (Retacrit®) in chemotherapy-induced anemia and the impact of iron supplementation. METHODS: This was a longitudinal, observational, prospective study of 12-16 weeks conducted in 195 French centers. The primary endpoint was the achievement of target Hb (with an increase of Hb ≥1 g/dL) or an increase of Hb ≥2 g/dL, in the absence of transfusion in the previous 3 weeks. RESULTS: 2,076 patients (women, 50.6%; mean age, 67.0 years) with malignant diseases (solid tumors, 79.8%; lymphomas, 12.7%; multiple myeloma, 6.6%) were analyzed. A total of 655 patients received oral iron (40.5%), intravenous iron (58.9%), or both (0.6%). At inclusion, 10.0% and 18.2% of patients without and with iron supplementation had serum ferritin <100 µg/L, respectively. Transferrin saturation (TSAT) ≤20% was more frequent in patients with supplementation (76.6%) than without supplementation (33.9%). The mean weekly doses of epoetin alfa biosimilar and planned duration of treatment were comparable regardless of iron supplementation. The primary endpoint was achieved in 70.5% and 70.2% of patients without and with iron supplementation, respectively. Three (0.1%) serious thromboembolic events related to treatment with epoetin alfa biosimilar were reported. CONCLUSION: Epoetin alfa biosimilar was effective and well tolerated for treating chemotherapy-induced anemia. Patients in subgroup with iron supplementation had lower TSAT at inclusion compared to subgroup without supplementation. Comparable mean Hb levels were achieved in both subgroups. The rate of patients with iron supplementation through the intravenous route was however insufficient.

Paclitaxel with or without pazopanib for ovarian cancer relapsing during bevacizumab maintenance therapy: The GINECO randomized phase II TAPAZ study.

BACKGROUND: Anti-angiogenic rechallenge with bevacizumab plus chemotherapy is effective in recurrent ovarian cancer (rOC); however, data are limited on tyrosine kinase inhibitors after progression on maintenance bevacizumab. METHODS: In the randomized phase II TAPAZ trial, patients with rOC during the first year of bevacizumab maintenance therapy were assigned 2:1 to either weekly paclitaxel 65 mg/m2 plus pazopanib 600-800 mg daily or standard weekly paclitaxel 80 mg/m2. The primary endpoint was 4-month progression-free survival (PFS) rate. RESULTS: Overall, 116 patients were randomized and treated: 79 with combination therapy and 37 with single-agent paclitaxel. Median follow-up was 13.1 months. There was no difference between treatment arms in 4-month PFS rate (61% [95% CI, 51-73%] with the combination versus 68% [95% CI, 54-85%] with paclitaxel alone), median PFS (4.9 [95% CI, 4.1-6.1] versus 5.8 [95% CI, 4.8-7.4] months, respectively) or median overall survival (13.6 versus 12.9 months, respectively). The combination was associated with more grade 3/4 toxicities (87% versus 70%, respectively) and toxicity-related paclitaxel discontinuations (22% versus 11%). Pazopanib was discontinued for toxicity in 44% of patients, most commonly for gastrointestinal and vascular events. There were two treatment-related deaths, both in the combination arm (pulmonary embolism and gastrointestinal perforation). At month 4, patient-reported outcomes deteriorated from baseline in the combination arm, particularly for abdominal/gastrointestinal symptoms, which showed a clinically important difference versus paclitaxel alone. CONCLUSIONS: In rOC progressing during maintenance bevacizumab, adding pazopanib to paclitaxel did not improve efficacy, increased toxicity, and compromised chemotherapy delivery.

Use of iron sucrose and red blood cell transfusions in anaemic cancer patients in France (OncoFer study).

PURPOSE: This report describes the results of an observational, retrospective cohort study, evaluating the use of iron sucrose (IS) and red blood cell (RBC) transfusions in patients with cancer in routine clinical practice in France. A parallel investigated cohort treated with ferric carboxymaltose (FCM) has been reported earlier. METHODS: Data of patients with a solid tumour or haematological malignancy who have received IS or an RBC transfusion during 2010 from 3 months prior (M-3) to 3 months post first treatment (M+3) were analysed. RESULTS: Data from 46 patients who had received IS (400 mg median total iron dose) and 357 patients who had received RBC transfusions as first treatment (baseline) were included. Median haemoglobin levels improved from 9.9 g/dL (interquartile range 9.2; 11.0 g/dL) at baseline to 12.4 g/dL (11.4; 13.1 g/dL) at M+3 in IS-treated patients and from 8.2 g/dL (7.8; 8.8 g/dL) at baseline to 10.1 g/dL (8.8; 11.1 g/dL) in transfused patients. An erythropoiesis-stimulating agent was given to 54.3 and 28.9% of patients in the IS and the RBC transfusion groups, respectively, resulting in slightly better mean haemoglobin increase in both groups (2.4 vs 1.5 g/dL and 2.0 vs 1.6 g/dL, respectively). No severe nor serious adverse reaction and no hypersensitivity reactions were reported. CONCLUSION: Both IS and RBC transfusions effectively increased Hb levels in patients with cancer. IS was safe and well tolerated in this population. Considering prior reported results with FCM, using FCM may reduce ESA dose requirements and the required number of infusions.

A prospective observational study on the evaluation of everolimus-related adverse events in metastatic renal cell carcinoma after first-line anti-vascular endothelial growth factor therapy: the AFINITE study in France.

PURPOSE: The objective of the study was to describe the occurrence of stomatitis and noninfectious lung disease in patients with metastatic renal cell carcinoma (mRCC) treated with second-line everolimus in a real-world setting. METHODS: This multicenter, prospective, observational study was conducted in France by physicians with experience of treatment of patients with mRCC. Patients aged ≥18 years who received everolimus after first-line antivascular endothelial growth factor (VEGF) therapy were included in the study. The primary safety assessments were occurrence of stomatitis (in terms of severity, event dates, and therapeutic management) and noninfectious pneumonitis (in terms of detection methodology, severity, event dates, and therapeutic management). RESULTS: Between September 2010 and August 2012, 284 patients were enrolled at 77 centers, of whom, 274 received everolimus therapy. Most patients had mRCC of clear cell histology (88%), and most of them (84%) received first-line sunitinib. In total, 40% of patients experienced treatment-related stomatitis, and 15% of patients experienced noninfectious lung disease. Most of them had a single episode. The incidence of grade 3 stomatitis and noninfectious lung disease were 8 and 3%, respectively. Mean time to the first episode was 27 days for stomatitis and 72 days for noninfectious lung disease from treatment initiation. Stomatitis and noninfectious lung disease resulted in treatment discontinuations in 2 and 7% of patients, respectively. The primary first-episode treatment was mouthwash (86%) for stomatitis and corticosteroids (65%) for noninfectious lung disease. CONCLUSIONS: This study confirms that stomatitis and noninfectious lung disease are commonly associated with everolimus use. Both adverse events were rarely severe and were managed easily and efficiently.

Efficacy and safety of Vinflunine for advanced or metastatic urothelial carcinoma in routine practice based on the French multi-centre CURVE study.

BACKGROUND: To retrospectively assess the efficacy and safety of Vinflunine (VFL) under routine conditions and identify overall survival (OS) prognostic factors. METHODS: Twenty centres participated in the retrospective study (minimum 4 patients undergoing VFL treatment for advanced/metastatic UC after platinum-based regimen progression. Primary endpoint was OS. Secondary endpoints: progression-free survival (PFS), radiological response rate (RR) RECIST criteria and toxicity (CTC NCI v3). RESULTS: These centres enrolled 134 patients. Prior chemotherapy (CT) lines (≥ 1 palliative): 1 and ≥ 2 in 69% and 26% of patients, respectively. Performance status (PS): 0, 1, 2 in 25%, 46% and 23% of patients. Median OS = 8.2 months [6.5-9.4], PFS = 4.2 months and RR 22%, median number of 5 cycles. In risk groups based on 0-3 presence of adverse prognostic factors (PS ≥ 1, haemoglobin ≤ 10 g/dl and liver metastasis), median OS: 13.2, 9.9, 3.6, and 2.4 months (P < .0001), respectively; 3.3 months (1.9-5.6) in PS ≥ 2 subgroup. CONCLUSION: This study reflects routine UC management and confirmed VFL patient efficacy. The drug is safe with gastro-intestinal and haematological prophylaxis. Analysis of prognostic factors for OS is consistent with pivotal trials.

Prospective Clinical Utility Study of the Use of the 21-Gene Assay in Adjuvant Clinical Decision Making in Women With Estrogen Receptor-Positive Early Invasive Breast Cancer: Results From the SWITCH Study.

BACKGROUND: The 21-gene Oncotype DX Recurrence Score assay is a validated assay to help decide the appropriate treatment for estrogen receptor-positive (ER+), early-stage breast cancer (EBC) in the adjuvant setting. The choice of adjuvant treatments might vary considerably in different countries according to various treatment guidelines. This prospective multicenter study is the first to assess the impact of the Oncotype DX assay in the French clinical setting. METHODS: A total of 100 patients with ER+, human epidermal growth factor receptor 2-negative EBC, and node-negative (pN0) disease or micrometastases in up to 3 lymph nodes (pN1mi) were enrolled. Treatment recommendations, physicians' confidence before and after knowing the Recurrence Score value, and physicians' perception of the assay were recorded. RESULTS: Of the 100 patients, 95 were evaluable (83 pN0, 12 pN1mi). Treatment recommendations changed in 37% of patients, predominantly from chemoendocrine to endocrine treatment alone. The proportion of patients recommended chemotherapy decreased from 52% pretest to 25% post-test. Of patients originally recommended chemotherapy, 61% were recommended endocrine treatment alone after receiving the Recurrence Score result. For both pN0 and pN1mi patients, post-test recommendations appeared to follow the Recurrence Score result for low and high values. Physicians' confidence improved significantly. CONCLUSION: These are the first prospective data on the impact of the Oncotype DX assay on adjuvant treatment decisions in France. Using the assay was associated with a significant change in treatment decisions and an overall reduction in chemotherapy use. These data are consistent with those presented from European and non-European studies.

A potentially neuroprotective role for erythropoietin with paclitaxel treatment in ovarian cancer patients: a prospective phase II GINECO trial.

PURPOSE: A prospective phase II multicenter study was performed in two steps in paclitaxel-treated ovarian cancer patients in France. A French version of the four-item Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx) questionnaire was validated. This was then used to evaluate neurotoxicity in relation to erythropoietin treatment. METHODS: Patients received standard second-line paclitaxel-based chemotherapy and erythropoietin for anemia. Neurotoxicity and hemoglobin levels were evaluated every cycle with the FACT/GOG-Ntx and NCI-CTCAE. The translated questionnaire was tested in 20 patients to confirm the translation accuracy. The final questionnaire was validated in 98 patients with internal consistency (Cronbach's coefficient) and item correlation (Pearson's r coefficient) tests. Neurotoxicity severity was analyzed according to erythropoietin intake (first three cycles versus no or late intake) and correlated with anemia. RESULTS: Patients received a median of six paclitaxel cycles (range 1-9). Neurotoxicity was validated in 484 questionnaires. Internal consistency was excellent with Cronbach's coefficients of ≥0.89 at inclusion, after 3 cycles and at study end. Inter-question correlation was high with Pearson's coefficients of 0.65-0.85. FACT/GOG-Ntx and NCI-CTCAE severity scoring was similar. Globally, the incidence of severe neurotoxicity (FACT/GOG-Ntx and NCI-CTCAE) was found significantly higher in patients with severe anemia. Of 98 evaluable patients, 31 received erythropoietin during the first three cycles. Mean hemoglobin level was significantly lower in this group from baseline to cycle 4; however, these anemic patients with early EPO intake did not develop an increase rate of severe neurotoxicity. CONCLUSIONS: The French FACT/GOG-Ntx questionnaire is a reliable and valid tool for assessing chemotherapy-induced neuropathy. This study raises the possibility that erythropoietin might play a neuroprotective role when administered with paclitaxel.

Treatment patterns, clinical outcomes and health care costs associated with HER2-positive breast cancer with central nervous system metastases: a French multicentre observational study.

BACKGROUND: The population of patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer (BC) who develop central nervous system (CNS) metastases is growing. Treatment strategies in this population are highly diverse. The objective of the study was to assess health care costs for the management of HER2 positive BC with CNS metastases. METHODS: This multicentre, retrospective, observational study was conducted on HER2-positive BC patients diagnosed with CNS metastases between 2006 and 2008. Data were extracted from patient medical records to estimate health care resource use. A partitioned estimator was used to adjust censoring costs by use of the Kaplan-Meier survival estimate. RESULTS: 218 patients were included and costs were estimated for 200 patients. The median time to detection of CNS metastases was 37.6 months. The first metastatic event involved the CNS in 39 patients, and this was the unique first metastatic site in 31 of these patients. Two years following diagnosis of CNS metastases, 70.3% of patients had died. The mean per capita cost of HER2-positive BC with CNS metastases in the first year following diagnosis was €35,735 [95% CI: 31,716-39,898]. The proportion of costs attributed to expensive drugs and those arising from hospitalisation were in the same range. CONCLUSION: A range of individualised disease management strategies are used in HER2-positive BC patients with CNS metastases and the treatments used in the first months following diagnosis are expensive. The understanding of cost drivers may help optimise healthcare expenditure and inform the development of appropriate prevention policies.

Daily practices in chemotherapy for advanced gastric or gastroesophageal junction adenocarcinoma: METESTOMAC French prospective cohort.

BACKGROUND: Around 50% of gastric cancers are diagnosed at an advanced stage. Several chemotherapy regimens are now internationally validated. Few data are available on the routine daily management of advanced gastric or gastroesophageal junction cancers. We aimed to describe chemotherapy practices, tolerance, and efficacy overall survival (OS) and Progression free survival (PFS) in a prospective French cohort. METHODS: Patients starting palliative chemotherapy were prospectively enrolled in 49 French centres. The primary objective was to report and describe patients' characteristics and treatment strategies. Secondary objectives were OS, PFS, objective response rate, adverse events rate, performance status deterioration during the chemotherapy. RESULTS: A total of 182 patients were included; 179 were analysed. Most patients received platinium-based chemotherapy as the first treatment and FOLFIRI as second; 62.0% of patients received a second line, and 32.4% a third line. More than two thirds of Her2-positive patients were first treated with trastuzumab. The FOLFIRI regimen was the most frequently used second-line therapy. Median OS was 13.3 months, similar whatever the chemotherapy or combinations used in the first line. One- and 2-year OS increased with the number of chemotherapy lines received, from respectively 24.7% and 5.7% (1 line), to 46.9% and 12.4% (2 lines) and 88.1% and 29.9% (3 or more lines) (p < 0.0001). CONCLUSION: Our study showed that treatment strategies in France are based on a succession of doublets, making it possible to offer a second and third line of treatment more often. This treatment strategy must be taken into account for future trials with immunotherapy combinations.

Retrospective analysis of real-world data to evaluate actionability of a comprehensive molecular profiling panel in solid tumor tissue samples (REALM study).

INTRODUCTION: Considering the growing interest in matched cancer treatment, our aim was to evaluate the ability of a comprehensive genomic profiling (CGP) assay to propose at least one targeted therapy given an identified genomic alteration or signature (actionability), and to collect the treatment modifications based on the CGP test results in clinical practise for solid tumors. METHODS: This retrospective, multicentre French study was conducted among 25 centres that participated in a free of charge program between 2017 and 2019 for a tissue CGP test. Data were collected on the patient, disease, tumor genomic profile, treatment suggested in the report (related to the genomic profile results) and subsequent therapeutic decisions according to the physician's declaration. RESULTS: Among the 416 patients, most had lung cancer (35.6%), followed by biliary tract cancer (11.5%) or rare cancers (11.1%); 75% had a metastatic disease. The actionability was 75.0% (95% CI [70.6%-78.9%]) for all patients, 85.1% and 78.4%, respectively in lung cancer and metastatic patients. After exclusion of clinical trial suggestions, the actionability decreased to 62.3% (95% CI [57.5%-66.8%]). Treatment modification based on the test results was observed in 17.3% of the patients and was more frequent in metastatic disease (OR = 2.73, 95% CI [1.31-5.71], p = 0.007). The main reasons for no treatment modification were poor general condition (33.2%) and stable disease or remission (30.2%). The genomic-directed treatment changes were performed mostly during the first six months after the CGP test, and interestingly a substantial part was observed from six to 24 months after the genomic profiling. CONCLUSION: This French study provides information on the real-life actionability of a CGP test based on tissue samples, and trends to confirm its utility in clinical practice across the course of the disease, in particularly for patients with lung cancer and/or advanced disease.

Long Terms Follow-Up of the Randomized MetaspHER Study Comparing Intravenous Versus Subcutaneous Trastuzumab in Patients' With HER2-Positive Metastatic Breast Cancer.

INTRODUCTION: The subcutaneous (H-SC) formulation of trastuzumab was demonstrated to be as effective and safe as intravenous (H-IV) and highly preferred by patients in early breast cancer. The present randomized MetaspHER trial (NCT01810393) has been the first study assessing patient's preference in metastatic setting and we report the final analysis with long term follow-up. METHODS: Patients with HER2-positive metastatic breast cancer who completed a first line chemotherapy with trastuzumab and achieved a long terms response lasting more than 3 years were randomized to receive 3 cycles of 600 mg fixed-dose H-SC, followed by 3 cycles of standard H-IV, or the reverse sequence. The primary endpoint was overall preference for H-SC or H-IV at cycle 6 and was previously reported. Secondary endpoints included safety over 1 year of treatment and with 4 additional years follow up. Overall survival (OS) and progression free survival (PFS) were assessed in this final analysis. RESULTS: A total of 113 patients were randomized and treated and the median follow-up duration was 45.4 months (range: 0.8-48.8). After the cross over period all patients excepted 2 pursued the H-SC. During the 18 cycles overall treatment period, at least 1 adverse event (AE), 1 AE of grade ≥3, and 1 serious adverse events (SAE) were respectively reported among 104 patients (92.0%), 23 patients (20.4%), and 16 patients (14.2%), respectively. Also, 10 patients (8.9%) experienced at least 1 cardiac event, including 4 patients (3.5%) with ejection fraction decreased. Beyond cycle 18 no significant additional safety concern emerged. PFS and OS rates at months 42 were 74.8% (64.7%-82.4%) and 94.9% (88.2%-97.9%), respectively. No factor appeared related to the survival outcome excepted the complete response status at baseline. CONCLUSION: The safety was consistent with the known H-IV and H-SC profiles without any safety concern raised over a prolonged exposure to H-SC.

Rucaparib for the Treatment of Metastatic Castration-resistant Prostate Cancer Associated with a DNA Damage Repair Gene Alteration: Final Results from the Phase 2 TRITON2 Study.

BACKGROUND: Initial TRITON2 (NCT02952534) results demonstrated the efficacy of rucaparib 600 mg BID in patients with metastatic castration-resistant prostate cancer (mCRPC) associated with a BRCA1 or BRCA2 (BRCA) or other DNA damage repair (DDR) gene alteration. OBJECTIVE: To present the final data from TRITON2. DESIGN, SETTING, AND PARTICIPANTS: TRITON2 enrolled patients with mCRPC who had progressed on one or two lines of next-generation androgen receptor-directed therapy and one taxane-based chemotherapy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was objective response rate (ORR; as per the modified Response Evaluation Criteria in Solid Tumor Version 1.1/Prostate Cancer Clinical Trials Working Group 3 criteria in patients with measurable disease by independent radiology review [IRR]); prostate-specific antigen (PSA) response rate (≥50% decrease from baseline [PSA50]) was a key secondary endpoint. RESULTS AND LIMITATIONS: As of July 27, 2021 (study closure), TRITON2 had enrolled 277 patients, grouped by mutated gene: BRCA (n = 172), ATM (n = 59), CDK12 (n = 15), CHEK2 (n = 7), PALB2 (n = 11), or other DDR gene (Other; n = 13). ORR by IRR was 46% (37/81) in the BRCA subgroup (95% confidence interval [CI], 35-57%), 100% (4/4) in the PALB2 subgroup (95% CI, 40-100%), and 25% (3/12) in the Other subgroup (95% CI, 5.5-57%). No patients within the ATM, CDK12, or CHEK2 subgroups had an objective response by IRR. PSA50 response rates (95% CI) in the BRCA, PALB2, ATM, CDK12, CHEK2, and Other subgroups were 53% (46-61%), 55% (23-83%), 3.4% (0.4-12), 6.7% (0.2-32%), 14% (0.4-58%), and 23% (5.0-54%), respectively. CONCLUSIONS: The final TRITON2 results confirm the clinical benefit and manageable safety profile of rucaparib in patients with mCRPC, including those with an alteration in BRCA or select non-BRCA DDR gene. PATIENT SUMMARY: Almost half of TRITON2 patients with BRCA-mutated metastatic castration-resistant prostate cancer had a complete or partial tumor size reduction with rucaparib; clinical benefits were also observed with other DNA damage repair gene alterations.

Genomic Instability Is Defined by Specific Tumor Microenvironment in Ovarian Cancer: A Subgroup Analysis of AGO OVAR 12 Trial.

BACKGROUND: Following disappointing results with PD-1/PD-L1 inhibitors in ovarian cancer, it is essential to explore other immune targets. The aim of this study is to describe the tumor immune microenvironment (TME) according to genomic instability in high grade serous ovarian carcinoma (HGSOC) patients receiving primary debulking surgery followed by carboplatin-paclitaxel chemotherapy +/- nintedanib. METHODS: 103 HGSOC patients' tumor samples from phase III AGO-OVAR-12 were analyzed. A comprehensive analysis of the TME was performed by immunohistochemistry on tissue microarray. Comparative genomic hybridization was carried out to evaluate genomic instability signatures through homologous recombination deficiency (HRD) score, genomic index, and somatic copy number alterations. The relationship between genomic instability and TME was explored. RESULTS: Patients with high intratumoral CD3+ T lymphocytes had longer progression-free survival (32 vs. 19.6 months, p = 0.009) and overall survival (OS) (median not reached). High HLA-E expression on tumor cells was associated with a longer OS (median OS not reached vs. 52.9 months, p = 0.002). HRD profile was associated with high HLA-E expression on tumor cells and an improved OS. In the multivariate analysis, residual tumor, intratumoral CD3, and HLA-E on tumor cells were more predictive than other parameters. CONCLUSIONS: Our results suggest HLA-E/CD94-NKG2A/2C is a potential immune target particularly in the HRD positive ovarian carcinoma subgroup.

Real-World Safety and Efficacy Outcomes with Abiraterone Acetate Plus Prednisone or Prednisolone as the First- or Second-Line Treatment for Metastatic Castration-Resistant Prostate Cancer: Data from the Prostate Cancer Registry.

BACKGROUND: Despite standard-of-care androgen-deprivation therapy and an increasing number of treatment options, the mortality rate for prostate cancer remains high. Progress to metastatic castration-resistant prostate cancer (mCRPC) necessitates additional treatments. Abiraterone acetate plus prednisone or prednisolone (AAP) prolongs survival in chemotherapy-naive and docetaxel-experienced patients. OBJECTIVE: To evaluate the real-world safety and efficacy of AAP as first-line and second-line [post-docetaxel only (AAP-PD)] treatment in patients with mCRPC. PATIENTS AND METHODS: The Prostate Cancer Registry (PCR) was a prospective, international, observational study of patients with mCRPC in routine clinical practice. Men aged ≥ 18 years with confirmed mCRPC were included. Baseline characteristics, safety (treatment-emergent adverse events, treatment-emergent severe adverse events), and efficacy [progression-free survival (PFS) and overall survival (OS)] were analyzed. RESULTS: At baseline, patients who received first-line AAP (n = 754) were generally older than patients who received AAP-PD (n = 354); median age was 76 years and 70 years, respectively. However, the rate of visceral metastasis was higher in the AAP-PD cohort than in the AAP cohort (17.7% vs. 9.6%, respectively). Demographics and disease characteristics of patients with baseline cardiovascular disease were similar to those of the overall registry population. Efficacy outcomes were similar for all patients, regardless of the line of AAP therapy. For first-line AAP and AAP-PD, respectively, the median PFS was 8.9 and 5.8 months for all patients and 9.1 and 6.0 months for patients with cardiovascular comorbidities; median OS was 27.1 and 23.4 months for all patients, and 27.4 and 23.1 months for patients with cardiovascular comorbidities. There were no unexpected adverse events in any patient subgroup. CONCLUSIONS: These real-world data complement the findings from randomized controlled trials, indicating that first- and second-line AAP is well tolerated and effective in patients with mCRPC, including those with underlying CV comorbidities. TRIAL REGISTRATION NUMBER: NCT02236637, registered 8 September 2014.

Cemiplimab for Locally Advanced and Metastatic Cutaneous Squamous-Cell Carcinomas: Real-Life Experience from the French CAREPI Study Group.

Although cemiplimab has been approved for locally advanced (la) and metastatic (m) cutaneous squamous-cell carcinomas (CSCCs), its real-life value has not yet been demonstrated. An early-access program enrolled patients with la/mCSCCs to receive cemiplimab. Endpoints were best overall response rate (BOR), progression-free survival (PFS), overall survival (OS), duration of response (DOR) and safety. The 245 patients (mean age 77 years, 73% male, 49% prior systemic treatment, 24% immunocompromised, 27% Eastern Cooperative Oncology Group performance status (PS) ≥ 2) had laCSCCs (35%) or mCSCCs (65%). For the 240 recipients of ≥1 infusion(s), the BOR was 50.4% (complete, 21%; partial, 29%). With median follow-up at 12.6 months, median PFS was 7.9 months, and median OS and DOR were not reached. One-year OS was 73% versus 36%, respectively, for patients with PS < 2 versus ≥ 2. Multivariate analysis retained PS ≥ 2 as being associated during the first 6 months with PFS and OS. Head-and-neck location was associated with longer PFS. Immune status had no impact. Severe treatment-related adverse events occurred in 9% of the patients, including one death from toxic epidermal necrolysis. Cemiplimab real-life safety and efficacy support its use for la/mCSCCs. Patients with PS ≥ 2 benefited less from cemiplimab, but it might represent an option for immunocompromised patients.

Real-World Outcomes in First-Line Treatment of Metastatic Castration-Resistant Prostate Cancer: The Prostate Cancer Registry.

BACKGROUND: Metastatic prostate cancer has a 30% 5-year survival rate despite recent therapeutic advances. There is a need to improve the clinical understanding and treatment of this disease, particularly in the real-world setting and among patients who are under-represented in clinical trials. OBJECTIVE: We aimed to evaluate the characteristics and clinical outcomes of patients who received their first treatment for metastatic castration-resistant prostate cancer (mCRPC) in routine clinical practice, independent of treatment used, including subgroups with baseline cardiac disease, diabetes mellitus, or visceral metastases. PATIENTS AND METHODS: Prospective, noninterventional analysis of patient record data in the multicenter Prostate Cancer Registry (PCR) of men with mCRPC. The data were collected in 16 countries with the aim of recruiting more than 3000 patients between 2013 and 2016. The study end date was 9 July 2018. Data evaluated included baseline characteristics, treatment exposure, and efficacy outcomes [overall survival (OS) and time to progression (TTP)] of patients treated with abiraterone acetate plus prednisone or prednisolone (collectively, "abiraterone"), enzalutamide, or docetaxel. Descriptive outcomes are reported from the overall patient population and subgroups of patients with baseline cardiovascular disease, diabetes mellitus, or visceral metastases. The treatment effects for time to progression were compared for the overall patient population. RESULTS: The study enrollment period lasted 2.5 years, and each patient was followed for a maximum of 3 years. A total of 1874 patients in the PCR had not received previous mCRPC treatment at baseline, although they had received androgen-deprivation therapy. Prevalent co-morbidities included cardiovascular disease in 65.4% and diabetes mellitus in 17.4% of patients. Baseline characteristics suggested that patients with more advanced disease received docetaxel treatment. In the overall patient population, the median time to progression with abiraterone, enzalutamide, and docetaxel as first-line mCRPC therapy was 9.6, 10.3, and 7.6 months, respectively, and median OS was 27.1, 27.1, and 27.9 months, respectively. Outcomes in the subgroups of patients with cardiovascular disease or diabetes mellitus were similar to those of the whole population in the analysis. As expected, patients with visceral metastases had shorter TTP and OS than patients in the overall population. CONCLUSIONS: This analysis shows, for the first time, the effectiveness in parallel of first-line abiraterone, enzalutamide, and docetaxel in mCRPC, including in patients with co-morbidities such as cardiovascular disease or diabetes mellitus or in patients with visceral metastases. These real-world findings from the PCR provide meaningful information to help manage mCRPC, particularly in patients under-represented in clinical studies. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT02236637; registered September 2014.

GINECO Prospective Non-interventional PROSPECTYON Study: Trabectedin Plus Pegylated Liposomal Doxorubicin for Platinum-sensitive Recurrent Ovarian Cancer.

BACKGROUND: Trabectedin and pegylated liposomal doxorubicin (PLD) is an effective combination therapy for platinum-sensitive recurrent ovarian cancer (ROC), particularly for disease relapsing within 6-12 months of platinum therapy. The non-interventional PROSPECTYON study evaluated trabectedin/PLD in French clinical practice. PATIENTS AND METHODS: Patients with ROC after at least one platinum-based regimen received 1.1 mg/m2 trabectedin plus 30 mg/m2 PLD every 3 weeks. Efficacy and safety were evaluated in subgroups according to platinum-free interval [6-12 versus ≥12 months (partially or fully platinum sensitive, respectively)]. RESULTS: Recurrent disease was partially platinum-sensitive in 58 patients and fully sensitive in 33 patients treated between July 2014 and June 2016. Patients in both subgroups received a median of six cycles of trabectedin and PLD. The most common grade 3 or more toxicities were haematological. Median progression-free survival was 6 months for both subgroups. CONCLUSION: Trabectedin/PLD is a valuable treatment option for partially or fully platinum-sensitive ROC.

Clinical progression is associated with poor prognosis whatever the treatment line in metastatic castration resistant prostate cancer: The CATS international database.

AIM OF THE STUDY: Our goal was to evaluate the impact of progression type (prostate-specific antigen [PSA] only, radiological or clinical) at initiation of first-, second- and third life-extending therapy (LET) on treatment outcomes in metastatic castration-resistant prostate cancer (mCRPC) patients, by performing a post-hoc analysis using data from the CATS international registry. METHODS: The 669 consecutive mCRPC patients of the CATS registry were classified according to their type of progression at initiation of each LET: PSA only (PSA-p), radiological (±PSA) (Radio-p); or clinical (±PSA, ±radiological) progression (Clin-p). Overall survival (OS), the primary endpoint, was calculated from initiation of the first-, second- and third-LET to death for each sequence. RESULTS: Median OS was shorter in the Clin-p group compared with the PSA-p group (14-month difference in first line; around 7-month difference in second- and third line). Shorter progression-free survival (PFS) was also observed in Clin-p patients, whatever the treatment is. Clinical progression seemed to be associated with a shorter duration of therapy with androgen receptor-targeted therapy (ART) compared with taxanes. CONCLUSIONS: Clinical progression at initiation of a LET is associated with poor outcomes including shorter PFS and OS as well as clinical and biological features of aggressive disease. Stratifying patients in clinical trials according to disease progression type may prevent selection bias and data heterogeneity. In daily practice, first signs of clinical progression may prompt physicians to consider starting a new LET, independently of PSA levels.

[Efficacy of weekly epoetin Beta in the treatment of chemotherapy-induced anemia in solid tumors]. / Efficacité de l'époétine bêta hebdomadaire dans l'anémie des tumeurs solides sous chimiothérapie.

OBJECTIVE: The aim of the study was to assess the efficacy and safety of epoetin beta once-weekly in anemic patients with solid tumors treated with chemotherapy. METHOD: Prospective, open-label, multicenter, single-arm study of epoetin beta 30 000 I.U. once-weekly in anemic patients with solid tumors receiving chemotherapy (n = 365). RESULTS: Epoetin beta increased mean haemoglobin (Hb) levels from 10.3 +/- 0.9 g/dL at baseline to 12.3+/-2.0 g/dL at week 12. The response rate was achieved in 61% (CI 95%: 55-68) of the patients. The mean Hb level increased was 1.8 g/dL (CI 95%: 1.5-2,0); in lung cancer patients (n = 102) Hb increase was 2.7 g/dL. Treatment with epoetin beta was well tolerated; only 1.4 % patients had thrombotic events. CONCLUSION: Epoetin beta (30 000 I.U. once weekly) increased Hb levels and was well-tolerated to correct anemia in patients with solid tumors treated with chemotherapy.

Efficacy and Safety of Two Neoadjuvant Strategies With Bevacizumab in MRI-Defined Locally Advanced T3 Resectable Rectal Cancer: Final Results of a Randomized, Noncomparative Phase 2 INOVA Study.

BACKGROUND: Recurrence and distant metastases remain a significant issue in locally advanced rectal cancer (LARC). Several multimodal strategies are assessed in clinical trials. PATIENTS AND METHODS: Patients with mid/low magnetic resonance imaging-defined high-risk LARC were randomized to arm A (12-week bevacizumab + FOLFOX-4 then bevacizumab-5-fluorouracil [5-FU]-radiotherapy [RT] before total mesorectal excision [TME]) or arm B (bevacizumab-5-FU-RT then TME). Long-term efficacy and safety up to 5 years' follow-up are reported. No comparison between arms was planned. RESULTS: Overall, 91 patients (46 in arm A and 45 in arm B) were included. Main results have been presented previously. During the late follow-up period (> 4 weeks after surgery), 4 patients (8.7%) in arm A and 4 (8.9%) in arm B experienced grade 3/4 adverse events related to bevacizumab; the most frequent were 2 anastomotic fistulas (both in arm A) and abscesses (1 in arm A and 2 in arm B). At 5 years' follow-up, 9 (19.6%) and 11 (24.4%) patients in arms A and B developed a fistula in the year after surgery, and 2 (4.3%) in arm A at > 1 year after surgery. Most resolved before study end. Five-year disease-free survival was 70% and 64.3% in arms A and B, respectively. Five-year overall survival was 90.5% (95% confidence interval, 76.7, 96.3) in arm A and 72.7% (95% confidence interval, 56.0, 83.9) in arm B. CONCLUSION: Neoadjuvant bevacizumab + FOLFOX-4 may have the potential to increase survival outcomes when followed by bevacizumab-5-FU-RT and TME in LARC. Bevacizumab-5-FU-RT then TME was associated with a higher-than-projected rate of anastomotic fistulas. Further research of neoadjuvant strategies in LARC is encouraged.
