Multicenter Prospective Study in HER2-Positive Early Breast Cancer for Detecting Minimal Residual Disease by Circulating Tumor DNA Analysis With Neoadjuvant Chemotherapy: HARMONY Study.

Background: Biomarkers to predict the recurrence risk are required to optimize perioperative treatment. Adjuvant chemotherapy for patients with human epidermal growth factor 2-positive (HER2-positive) early breast cancer is decided by pathological responses of neoadjuvant chemotherapy (NAC). However, whether pathological responses are appropriate biomarkers is unclear.

Final Safety and Health-Related Quality of LIfe Results of the Phase 2/3 Act.In.Sarc Study With Preoperative NBTXR3 Plus Radiation Therapy Versus Radiation Therapy in Locally Advanced Soft-Tissue Sarcoma.

Purpose: Act.In.Sarc (NCT02379845) demonstrated that the first-in-class radioenhancer NBTXR3, activated by preoperative radiation therapy (RT), doubled the rate of pathologic complete response after resection compared with preoperative RT alone in adult patients with locally advanced soft tissue sarcoma of the extremity or trunk wall (16.

Prophylactic strategies for hand-foot syndrome/skin reaction associated with systemic cancer treatment: a meta-analysis of randomized controlled trials.

Purpose: Hand-foot syndrome (HFS) and hand-foot skin reaction (HFSR) are common toxicities of several systemic cancer treatments. Multikinase inhibitor-induced HFSR is distinguished from chemotherapy-induced HFS in terms of pathogenesis, symptomatology, and treatment. Multiple trials have investigated the efficacy of preventive strategies such as COX-inhibitors, pyridoxine, and urea cream; however, no consensus has been made.

Long-Term Safety and Effectiveness of PF-05280014 (a Trastuzumab Biosimilar) Treatment in Patients with HER2-Positive Metastatic Breast Cancer: Updated Results of a Randomized, Double-Blind Study.

Background: PF-05280014 was compared with trastuzumab sourced from the European Union (trastuzumab-EU), each plus paclitaxel, as first-line treatment for human epidermal growth factor receptor 2-positive metastatic breast cancer in a phase III study. Equivalence between treatment groups was demonstrated.

Objective: The aim of this study was to report long-term safety and overall survival (OS) over 6 years after the first patient was screened.

Long-term efficacy and safety of CT-P6 versus trastuzumab in patients with HER2-positive early breast cancer: final results from a randomized phase III trial.

Purpose: Equivalent efficacy was demonstrated for the biosimilar CT-P6 and trastuzumab following neoadjuvant therapy for patients with human epidermal growth factor receptor-2 (HER2)-positive early breast cancer. Following adjuvant treatment, efficacy and safety were comparable between treatments. We report updated safety and efficacy data after up to 3 years' follow-up.

NBTXR3, a first-in-class radioenhancer hafnium oxide nanoparticle, plus radiotherapy versus radiotherapy alone in patients with locally advanced soft-tissue sarcoma (Act.In.Sarc): a multicentre, phase 2-3, randomised, controlled trial.

Background: Pathological complete response to preoperative treatment in adults with soft-tissue sarcoma can be achieved in only a few patients receiving radiotherapy. This phase 2-3 trial evaluated the safety and efficacy of the hafnium oxide (HfO) nanoparticle NBTXR3 activated by radiotherapy versus radiotherapy alone as a pre-operative treatment in patients with locally advanced soft-tissue sarcoma.

Methods: Act.

PF-05280014 (a trastuzumab biosimilar) plus paclitaxel compared with reference trastuzumab plus paclitaxel for HER2-positive metastatic breast cancer: a randomised, double-blind study.

Background: This randomised, double-blind study compared PF-05280014 (a trastuzumab biosimilar) with reference trastuzumab (Herceptin®) sourced from the European Union (trastuzumab-EU), when each was given with paclitaxel as first-line treatment for HER2-positive metastatic breast cancer.

Methods: Between 4 April 2014 and 22 January 2016, 707 participants were randomised 1:1 to receive intravenous PF-05280014 plus paclitaxel (PF-05280014 group; n = 352) or trastuzumab-EU plus paclitaxel (trastuzumab-EU group; n = 355). PF-05280014 or trastuzumab-EU was administered weekly (first dose 4 mg/kg, subsequent doses 2 mg/kg), with the option to change to a 3-weekly regimen (6 mg/kg) from Week 33.

CT-P6 compared with reference trastuzumab for HER2-positive breast cancer: a randomised, double-blind, active-controlled, phase 3 equivalence trial.

Background: CT-P6 is a proposed biosimilar to reference trastuzumab. In this study, we aimed to establish equivalence of CT-P6 to reference trastuzumab in neoadjuvant treatment of HER2-positive early-stage breast cancer.

Methods: In this randomised, double-blind, active-controlled, phase 3 equivalence trial, we recruited women aged 18 years or older with stage I-IIIa operable HER2-positive breast cancer from 112 centres in 23 countries.

Sunitinib in metastatic renal cell carcinoma: an ethnic Asian subpopulation analysis for safety and efficacy.

Aims: We evaluated and compared the safety and efficacy of sunitinib in Asian and non-Asian patients with metastatic renal cell carcinoma enrolled in a previously reported global expanded access program.

Methods: Previously treated and treatment-naïve patients received open-label sunitinib at a starting dose of 50 mg/day for 4 weeks, followed by 2 weeks off treatment, in repeated 6-week cycles. Safety was assessed regularly, tumor measurements were performed per local practice, and survival data collected where possible.

Efficacy and safety of ixabepilone plus capecitabine in elderly patients with anthracycline- and taxane-pretreated metastatic breast cancer.

Objectives: Data on chemotherapy regimens in elderly patients with metastatic breast cancer (MBC) are limited. The aim of this retrospective pooled analysis was to determine efficacy and safety of ixabepilone plus capecitabine versus capecitabine alone in patients with MBC aged ≥ 65 years.

Materials And Methods: A total of 1973 patients with MBC previously treated with or resistant to anthracyclines and taxanes were randomized in two open-label, multinational, phase 3 studies (study 046 and study 048).

Maintenance of clinical efficacy after dose reduction of ixabepilone plus capecitabine in patients with anthracycline- and taxane-resistant metastatic breast cancer: a retrospective analysis of pooled data from 2 phase III randomized clinical trials.

Background: This retrospective analysis aimed to determine whether early dose reduction impacts the efficacy of ixabepilone plus capecitabine in women with metastatic breast cancer (MBC).

Patients And Methods: In 2 phase III trials, patients (N = 1973) with anthracycline/taxane-pretreated MBC were randomized to receive ixabepilone 40 mg/m(2) on day 1 plus capecitabine 1000 mg/m(2) twice daily (BID) on days 1 to 14 or single-agent capecitabine 1250 mg/m(2) BID on days 1 to 14 of a 3-week course. Because of the similar design and populations, data from trials were pooled to evaluate efficacy of the combination regimen among women who did or did not undergo ixabepilone dose reduction during the first 4 courses.

Analysis of overall survival from a phase III study of ixabepilone plus capecitabine versus capecitabine in patients with MBC resistant to anthracyclines and taxanes.

Limited proven treatment options exist for patients with metastatic breast cancer (MBC) resistant to anthracycline and taxane treatment. Ixabepilone, a novel semisynthetic analog of epothilone B, has demonstrated single-agent activity in MBC resistant to anthracyclines and taxanes. In combination with capecitabine in a phase III trial (CA163-046) in this setting, ixabepilone prolonged progression-free survival and increased objective response rate relative to capecitabine (Thomas et al.

Activity of ixabepilone in oestrogen receptor-negative and oestrogen receptor-progesterone receptor-human epidermal growth factor receptor 2-negative metastatic breast cancer.

Oestrogen receptor (ER)-negative breast cancer, including oestrogen receptor-, progesterone receptor- and human epidermal growth factor receptor 2-negative (ER/PR/HER2-negative) breast cancer, is more aggressive than ER-positive disease. A major limitation in the treatment of ER-negative disease subtypes is the inherent insensitivity to hormonal agents (tamoxifen, aromatase inhibitors) that are widely used in the treatment of breast cancer. Thus, therapeutic options for poor prognosis patients with ER-negative breast cancer are limited to a handful of chemotherapeutic agents, and new agents are needed to improve the treatment of this disease.

Ixabepilone plus capecitabine for metastatic breast cancer progressing after anthracycline and taxane treatment.

Purpose: Effective treatment options for patients with metastatic breast cancer resistant to anthracyclines and taxanes are limited. Ixabepilone has single-agent activity in these patients and has demonstrated synergy with capecitabine in this setting. This study was designed to compare ixabepilone plus capecitabine versus capecitabine alone in anthracycline-pretreated or -resistant and taxane-resistant locally advanced or metastatic breast cancer.
