Eribulin treatment for patients with metastatic breast cancer:The United Kingdom experience - a multicenter retrospective study

Introduction: This study examined real-world data from patients who received eribulin for metastatic breast cancer (MBC) collected from 14 hospitals across the UK. Methods: Anonymized data were collected retrospectively from patients with MBC who had received eribulin. The data included the hormone-receptor status, histological diagnosis, age, prior chemotherapy, response to eribulin, progression-free survival (PFS), and overall survival (OS). Results: Among 577 patients analyzed, the median age was 56 years, and most patients (73%) were estrogen-receptor positive. The median OS was 288 days (95% confidence interval [CI]: 261–315), and the PFS was 117 days (95% CI: 105–129). The median OS was higher among older patients (≥65 vs. p = 0.028). The median OS was also higher in patients who received eribulin after fewer prior lines of chemotherapy (≤2 vs. >2 prior: 328 days [95% CI: 264–385] vs. 264 days [95% CI: 229–298]; p = 0.042). Discussion/Conclusion: These retrospective data suggest that eribulin can be successfully used in older patients with MBC. Eribulin treatment was more effective in earlier-line settings, which, while predictable, supports consideration of eribulin as a second-line treatment option. </p

Phase II, open-label trial to assess QTcF effects, pharmacokinetics and antitumor activity of afatinib in patients with relapsed or refractory solid tumors

Afatinib is an irreversible ErbB family blocker currently under evaluation in late-stage clinical trials. This study primarily assessed the cardiac safety, pharmacokinetics and antitumor activity of afatinib in cancer patients. In this multicenter, Phase II, open-label, single-arm trial, 60 patients with solid tumors who were expected to express epidermal growth factor receptor-1 and HER2 received oral afatinib 50 mg daily. QTcF intervals (QT interval corrected by the Fridericia formula) were evaluated based on electrocardiogram recordings time-matched with pharmacokinetic blood samples after single (Day 1) and continuous (Day 14; steady state) administration. Adverse events were classified according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 3.0; antitumor activity was assessed using RECIST 1.0. There was a nonsignificant decrease of 0.3 ms (90 % confidence interval -2.8, 2.3; N = 49) in the mean of the average time-matched QTcF interval from baseline to steady state. The maximum plasma concentration for afatinib was seen at median t (max) 3 h after both single dose and at steady state. No relationship between afatinib plasma concentrations and time-matched QTcF, QT and heart rate change was found. The overall adverse event profile was consistent with the known safety profile of afatinib. One patient demonstrated a partial response (PR) and two patients unconfirmed PRs. Afatinib had no impact on cardiac repolarization, had a manageable safety profile and demonstrated antitumor activity in this uncontrolled study

The Impact of COVID-19 on the Delivery of Systemic Anti-Cancer Treatment at Guy’s Cancer Centre

Background: This study aimed to assess the outcome of cancer patients undergoing systemic anti-cancer treatment (SACT) at our centre to help inform future clinical decision-making around SACT during the COVID-19 pandemic. Methods: Patients receiving at least one episode of SACT for solid tumours at Guy’s Cancer Centre between 1 March and 31 May 2020 and the same period in 2019 were included in the study. Data were collected on demographics, tumour type/stage, treatment type (chemotherapy, immunotherapy, biological-targeted) and SARS-CoV2 infection. Results: A total of 2120 patients received SACT in 2020, compared to 2449 in 2019 (13% decrease). From 2019 to 2020, there was an increase in stage IV disease (62% vs. 72%), decrease in chemotherapy (42% vs. 34%), increase in immunotherapy (6% vs. 10%), but similar rates of biologically targeted treatments (37% vs. 38%). There was a significant increase in 1st and 2nd line treatments in 2020 (68% vs. 81%; p &lt; 0.0001) and reduction in 3rd and subsequent lines (26% vs. 15%; p = 0.004) compared to 2019. Of the 2020 cohort, 2% patients developed SARS-CoV2 infections. Conclusions: These real-world data from a tertiary Cancer Centre suggest that despite the challenges faced due to the COVID-19 pandemic, SACT was able to be continued without any significant effects on the mortality of solid-tumour patients. There was a low rate (2%) of SARS-CoV-2 infection which is comparable to the 1.4%-point prevalence in our total cancer population.</p
