Phase II study of eribulin in combination with gemcitabine for the treatment of patients with locally advanced or metastatic triple negative breast cancer (ERIGE trial). Clinical and pharmacogenetic results on behalf of the Gruppo Oncologico Italiano di Ricerca Clinica (GOIRC).

ABSTRACT:

Background

The combination of a microtubule inhibitor (eribulin) with a nucleoside analog (gemcitabine) may synergistically induce tumor cell death, particularly in triple negative breast cancer (TNBC) characterized by high cell proliferation, aggressive behavior, and chemo-resistance.

Patients and methods

This is an open-label, multicenter phase II study evaluating the combination of eribulin (0.88 mg/m²) plus gemcitabine (1000 mg/m²) on days 1 and 8 of a 21-day cycle as either first- or second-line treatment of locally advanced or metastatic TNBC. The primary endpoint was the objective response for evaluable patients. A prospective, molecular correlative study was carried out to assess the role of germinal BRCA pathogenic variants and single nucleotide polymorphisms (SNPs) in predicting efficacy and toxicity of the combination regimen.

Results

From July 2013 to September 2016, 83 evaluable patients were enrolled. They received a median number of six cycles of treatment. An overall response rate (ORR) of 37.3% (31 patients) was observed, with a complete response rate of 2.4% and a partial response rate of 34.9%; the clinical benefit rate was 48.8%. With a median follow-up of 28.8 months, the median response duration was 6.6 months, the median progression-free survival (PFS) was 5.1 months, and the median overall survival (OS) was 14.5 months. The most common grade 3-4 adverse events were aminotransferase elevation (in 25% of the patients) and neutropenia (in 23.8%). Women with BRCA1/2 pathogenic variants were associated with worse ORR, PFS, and OS than BRCA1/2 wild-type carriers. CYP3A4 and FGD4 SNPs were associated with increased risk of liver toxicity. Three different SNPs in CDA?2, RRM1, and CYP2C8 genes were significantly associated with poorer OS.

Conclusions

The combination of eribulin and gemcitabine showed promising activity and a moderate toxicity profile in metastatic TNBC. BRCA status and pharmacogenetics tests may help identify patients with high probability of response with negligible toxicity.

Project description:BACKGROUND:Rheumatoid arthritis (RA) is associated with an increased risk of morbidity and mortality, when compared with general population, largely due to enhanced atherosclerotic disease. In this work, we aimed at assessing both occurrence and predictive factors of subclinical and clinical atherosclerosis in RA. METHODS:From January 1, 2015, to December 31, 2015, consecutive participants with RA, admitted to Italian Rheumatology Units, were assessed in the GIRRCS (Gruppo Italiano di Ricerca in Reumatologia Clinica e Sperimentale) cohort. After that, those participants were followed up in a 3-year, prospective, observational study, assessing the occurrence of subclinical and clinical atherosclerosis and possible predictive factors. McNemar test was employed to assess the changes in subclinical and clinical atherosclerosis, and regression analyses exploited the ORs for the occurrence of those comorbidities. RESULTS:We analysed 841 participants, mostly female (82.2%) and with median age of 60?years (range 21-90). The remission was achieved and maintained by 41.8% of participants during the follow-up. We observed an increased rate of subclinical atherosclerosis at the end of follow-up (139 vs 203 participants, p?<?0.0001), particularly in participants with a disease duration less than 5?years at baseline (70 participants vs 133 participants, p?<?0.0001). Type 2 diabetes (T2D) (OR 4.50, 95%CI 1.74-11.62, p?=?0.002), high blood pressure (OR 2.03, 95%CI 1.04-4.14, p?=?0.042), ACPA (OR 2.36, 95%CI 1.19-4.69, p?=?0.014) and mean values of CRP during the follow-up (OR 1.07, 95%CI 1.03-1.14, p?=?0.040) were significantly associated with higher risk of subclinical atherosclerosis. We observed an increased rate of clinical atherosclerosis at the end of follow-up (48 vs 76 participants, p?<?0.0001). T2D (OR 6.21, 95%CI 2.19-17.71, p?=?0.001) was associated with a significant risk of clinical atherosclerosis. The achievement and the maintenance of remission reduced the risk of subclinical (OR 0.25, 95%CI 0.11-0.56, p?=?0.001) and clinical atherosclerosis (OR 0.20, 95%CI 0.09-0.95, p?=?0.041). CONCLUSIONS:We reported an increased prevalence and incidence of both subclinical and clinical atherosclerosis in 3-year prospectively followed participants, mainly in the subset with a duration of disease less than 5?years. The achievement and the maintenance of remission are associated with a reduction of the risk of subclinical and clinical atherosclerosis. Among "traditional" cardiovascular risk factors, participants with T2D showed a higher risk of clinical and subclinical atherosclerosis.

Project description:Several studies have pointed out a significant association between rheumatoid arthritis (RA) and accelerated atherosclerosis. At the best of our knowledge, no such study has been carried out in a large Italian series and, in this study, we aimed to investigate the prevalence of both subclinical atherosclerosis and history of cardiovascular events (CVEs), in patients consecutively admitted from January 1, 2015 to December 31, 2015 to Rheumatology Units throughout the whole Italy.Centers members of GIRRCS (Gruppo Italiano di Ricerca in Reumatologia Clinica e Sperimentale) were invited to enrol patients consecutively admitted from January 1, 2015 to December 31, 2015 and satisfying American College of Rheumatology/ European League Against Rheumatism criteria for RA and to investigate each of them for: traditional cardiovascular risk factors: sex, age, smoking habit, total cholesterol, triglycerides, glycaemia, high blood pressure, metabolic syndrome (MS), type 2 diabetes (T2D); RA features: disease duration as assessed from the first symptom, disease activity as evaluated by DAS28, radiographic damage as assessed by hands and feet x-ray, and previous joint surgery; prevalence of both subclinical atherosclerosis and history of CVEs.Eight centers participated to the study. From January 1, 2015 to December 31, 2015, the 1176 patients, who had been investigated for all the items, were enrolled in the study. They were mostly women (80.52%), with a median age of 60 years (range, 18-91 years), a median disease duration of 12 years (range, 0.8-25 years), seropositive in 69.21%. Nineteen percent were in remission; 17.51% presented low disease activity; 39.45% moderate disease activity; 22.61% high disease activity.Eighty-two patients (6.9%) had a history for CVEs (58 myocardial infarction, 38 heart failure, 10 ischemic transitory attack, and 7 stroke). This figure appears to be lower than that reported worldwide (8.5%). After excluding the 82 patients with a history of CV events, subclinical atherosclerosis was detected in 16% of our patients, (176 patients), a figure lower than that reported worldwide (32.7%) and in previous Italian studies.This is the first Italian multicenter study on subclinical and clinical atherosclerosis in patients with RA. We pointed out a low prevalence of both subclinical atherosclerosis and history of CV events.

Project description:BackgroundEribulin mesylate is a novel, nontaxane, microtubule dynamics inhibitor. In this study, we assessed the efficacy and safety of eribulin versus eribulin plus the oral small-molecule tyrosine kinase inhibitor anlotinib in patients with locally recurrent or metastatic breast cancer.Patients and methodsIn this single-center, open-label, phase II clinical study (NCT05206656) conducted in a Chinese hospital, patients with human epidermal growth factor receptor 2 (HER2)-negative, locally recurrent or metastatic breast cancer previously treated with anthracycline- or taxane-based chemotherapy were randomized (1 : 1) to receive eribulin alone or in combination with anlotinib. The primary efficacy endpoint was investigator-assessed progression-free survival (PFS).ResultsFrom June 2020 to April 2022, a total of 80 patients were randomly assigned to either eribulin monotherapy or eribulin plus anlotinib combination therapy, with 40 patients in each group. The data cut-off was 10 August 2022. The median PFS was 3.5 months [95% confidence interval (CI) 2.8-5.5 months] for eribulin and 5.1 months (95% CI 4.5-6.9 months) for eribulin plus anlotinib (hazard ratio = 0.56, 95% CI 0.32-0.98; P = 0.04). The objective response rates were 32.5% versus 52.5% (P = 0.07), respectively, and disease control rates were 67.5% versus 92.5% (P = 0.01), respectively. Patients <50 years of age, with an Eastern Cooperative Oncology Group performance status score of 0, visceral metastasis, number of treatment lines of four or more, hormone receptor negative (triple-negative), and HER2 low expression appeared to benefit more from combined treatment. The most common adverse events in both groups were leukopenia (n = 28, 70.0%, patients in the eribulin monotherapy group versus n = 35, 87.5%, patients in the combination therapy group), aspartate aminotransferase elevations (n = 28, 70.0%, versus n = 35, 87.5%), neutropenia (n = 25, 62.5%, versus n = 31, 77.5%), and alanine aminotransferase elevations (n = 25, 62.5%, versus n = 30, 75.0%).ConclusionEribulin plus anlotinib can be considered an alternative treatment option for HER2-negative locally advanced or metastatic breast cancer.
