Biosimilars: Implications for Clinical Practice.

In 2015, the United States Food and Drug Administration (FDA) approved the first biosimilar, filgrastim-sndz, a biosimilar of the granulocyte colony-stimulating factor filgrastim. Since that time, the FDA has approved four additional biosimilar tumor necrosis factor α inhibitors, and, in May 2017, the Oncology Drug Advisory Committee voted in favor of approval of an epoetin alfa biosimilar. The patents of several widely used biologic cancer therapies (including trastuzumab, rituximab, bevacizumab, cetuxima...

Comparing granulocyte colony-stimulating factor filgrastim and pegfilgrastim to its biosimilars in terms of efficacy and safety: A meta-analysis of randomised clinical trials in breast cancer patients.

Granulocyte colony-stimulating factors (G-CSFs) are widely used to prevent neutropenia in cancer patients undergoing myelosuppressive chemotherapy. Several biosimilar medicines of G-CSF are now available, with their development involving a step-wise series of comparisons to demonstrate similarity to reference biologics. Randomised clinical trials (RCTs) are considered confirmatory, and for G-CSF biosimilars, patients with breast cancer (BC) undergoing myelosuppressive chemotherapy are the most sensitive pop...

Ado-trastuzumab emtansine (T-DM1) in HER2+ advanced breast cancer patients: does pretreatment with pertuzumab matter?

We evaluated the outcomes of patients treated with ado-trastuzumab emantasine (T-DM1) after first-line pertuzumab/trastuzumab, compared with those receiving a trastuzumab-only-based regimen.

Trastuzumab Plus Pertuzumab Resistance Does Not Preclude Response to Lapatinib Plus Trastuzumab in HER2-Amplified Colorectal Cancer.

Human epidermal growth factor 2 (HER2) amplification represents a distinct molecular subgroup of colorectal cancers that is associated with anti-epidermal growth factor receptor resistance and sensitivity to dual HER2 targeting. Although clinical trials have reported activity for trastuzumab/pertuzumab and trastuzumab/lapatinib combinations, there are no reports on lapatinib plus trastuzumab activity after resistance to trastuzumab plus pertuzumab. Presented are three cases of HER2 amplified colorectal canc...

The Global Need for a Trastuzumab Biosimilar for Patients With HER2-Positive Breast Cancer.

Trastuzumab improves survival outcomes for patients with HER2-positive (HER2) breast cancer, yet not all such women receive this important therapy. Trastuzumab was approved by the US Food and Drug Administration in 1998 and the European Medicines Agency in 2000 as treatment for HER2metastatic breast cancer (MBC). Observational studies between 2000 and 2015 in patients with HER2MBC suggest that nearly 12% in the United States, 27% to 54% in Europe, and 27.1% to 49.2% in China did not receive trastuzumab or a...

A randomised trial comparing the pharmacokinetics and safety of the biosimilar CT-P6 with reference trastuzumab.

Access to trastuzumab, a valuable anti-cancer treatment, can be limited by cost. The primary aim of this study was to evaluate and compare the PK profiles of CT-P6, a biosimilar of trastuzumab, and US-licensed reference trastuzumab (Herceptin®) in healthy subjects. Secondary study aims included comparison of the safety and immunogenicity of CT-P6 and reference trastuzumab in these subjects.

ASCO is committed to providing education and guidance to the oncology community on the use of biosimilars in the cancer setting; therefore, ASCO has developed this statement to offer guidance in the following areas: (1) naming, labeling, and other regulatory considerations, (2) safety and efficacy of biosimilars, (3) interchangeability, switching, and su...

Science of Biosimilars.

Biosimilar therapeutic proteins in oncology offer the potential to decrease costs while providing safety and efficacy profiles consistent with their respective reference or originator products. Biosimilars have a number of important differences from generic small-molecule drugs, including manufacturing processes that are unique from their reference products. These differences may affect biosimilars through posttranslational modifications that can occur in specific cellular production lines, and these modifi...

Survival outcomes for Australian women receiving trastuzumab for HER2-positive metastatic breast cancer following (neo)adjuvant trastuzumab: a national population-based observational study (2006-2014).

Patients treated with (neo)adjuvant trastuzumab who relapse and receive trastuzumab for metastatic breast cancer (MBC) are a growing population with little outcome data given their exclusion from most clinical trials. We aim to estimate survival outcomes for this trastuzumab 'pre-treated' population.

MiR-129-5p Sensitizes the Response of Her-2 Positive Breast Cancer to Trastuzumab by Reducing Rps6.

Trastuzumab is an important treatment used for patients with Her-2-positive breast cancer, but an increasing incidence of trastuzumab resistance has been observed clinically during the past decade. Aberrant microRNA (miR) expression levels are correlated with prognosis and response to trastuzumab in breast cancer. MiR-129-5p is downregulated in trastuzumab-resistant human breast cancer cells (JIMT-1), but its potential function and underlying mechanism remain unclear.

Effect of Pegfilgrastim Primary Prophylactic Administration on Relative Dose Intensity(RDI)in Postoperative Adjuvant Chemotherapy(TC Therapy)for Breast Cancer - A Single-Center, Retrospective Study.

This study assessed the effect of pegfilgrastim in patients with early stage breast cancer who were receiving docetaxel and cyclophosphamide(TC)therapy(75mg/m / 2 docetaxel plus 600 mg/m2 cyclophosphamide). In total, 17 patients who were to receive 4 planned cycles of TC therapy every 3 weeks were included in this study. Of the 17 patients, 10 who received pegfilgrastim after January 2016 formed the Peg-G group and 7 who did not receive pegfilgrastim until December 2015 formed the control group. We observed...

Refining the role of pegfilgrastim (a long-acting G-CSF) for prevention of chemotherapy-induced febrile neutropenia: consensus guidance recommendations.

Chemotherapy-induced febrile neutropenia (FN) causes treatment delays and interruptions and can have fatal consequences. Current guidelines provide recommendations on granulocyte colony-stimulating factors (G-CSF) for prevention of FN, but guidance is unclear regarding use of short- vs long-acting G-CSF (e.g., filgrastim vs pegfilgrastim/lipegfilgrastim, respectively). An international panel of experts convened to develop guidance on appropriate use of pegfilgrastim for prevention of chemotherapy-induced FN...

Biosimilars in Dermatology - theory becomes reality.

Biosimilars are biological medicines that are analogues of a specific reference product. Biosimilars of the tumor necrosis factor alpha inhibitors infliximab and etanercept are already approved and available for dermatological indications. Regulatory agencies require in-depth analysis of physicochemical and functional properties of these highly complex molecules as well as clinical data on their similarity regarding efficacy and safety in at least one clinical trial in a sensitive and homogeneous population...

Can we transfer the mechanisms of the generics market to biosimilars?

Personalized medicines such as biologics and their generic equivalents, biosimilars, are pouring onto the pharmaceutical markets. Data of 16 private health insurance companies were used to describe the market shares of selected biosimilars available in 2014 and 2015. The purpose of this study focuses on the question of whether market access of biosimilars will lead to a price competition of the expense of innovation competition. The results show that prescriptions of biosimilars made up 37% of total prescri...

The importance of biosimilars medicines for private and statutory health insurance.

Patented biopharmaceuticals generate huge costs for private and statutory health insurance. Exactly ten years ago, off-patent biopharmaceuticals, also referred to as 'biosimilars medicines', became available as a more cost-efficient and therapeutically equivalent alternative in Germany and Europe. Following their approval by all the relevant authorities, biosimilars medicines can therefore be applied in the same way as previously patented biopharmaceuticals.

NES1/KLK10 promotes trastuzumab resistance via activation of PI3K/AKT signaling pathway in gastric cancer.

Trastuzumab, a humanized antibody targeting human epidermal growth factor receptor 2 (HER2), exhibits remarkable therapeutic efficacy against HER2-positive gastric cancer. Acquired resistance to trastuzumab remains a barrier to patient survival and the mechanisms underlying this are still not well understood. The normal epithelial cell-specific-1 (NES1) gene, also named as KLK10, is recognized as a potential therapeutic target for reversing trastuzumab resistance. The aim of this study was to explore the po...

Switching Reference Medicines to Biosimilars: A Systematic Literature Review of Clinical Outcomes.

To evaluate the possibility that switching from reference biologic medicines to biosimilars could lead to altered clinical outcomes, including enhanced immunogenicity, compromised safety, or diminished efficacy for patients, a systematic literature review was conducted of all switching studies between related biologics (including biosimilars).

Antibody-nanoparticle conjugate constructed with trastuzumab and nanoparticle albumin-bound paclitaxel for targeted therapy of human epidermal growth factor receptor 2-positive gastric cancer.

Gastric cancer (GC) is the most lethal malignancy in the digestive system. This study investigated an antibody-nanoparticle conjugate (ANC) constructed with trastuzumab (Herceptin®) and nanoparticle albumin-bound paclitaxel (nab-paclitaxel, Abraxane®) (trastuzumab/nab‑paclitaxel) as a novel strategy of targeted therapy for human epidermal growth factor receptor 2 (HER2) positive GC. The ANC was fabricated with trastuzumab and nab‑paclitaxel by a 'one-step' synthesis using EDC/NHS. In vitro antitumor...

Correlation between human epidermal growth factor receptor 2 expression level and efficacy of trastuzumab beyond progression in metastatic gastric cancer.

There is currently no clinical data regarding the efficacy of trastuzumab treatment for the progression of human epidermal growth factor receptor 2 (HER2)-positive advanced gastric cancer (AGC) occurring during trastuzumab-based chemotherapy. The aim of this study was to retrospectively examine the clinical benefits of trastuzumab for HER2-positive AGC patients who progressed during first-line trastuzumab-based chemotherapy. Among the 108 patients treated with trastuzumab combined with fluoropyrimidine and ...

Modeling trastuzumab-related cardiotoxicity in vitro using human stem cell-derived cardiomyocytes.

Trastuzumab (Herceptin®), a monoclonal antibody against the ErbB2 (HER2) receptor, has significantly improved clinical outcomes for HER2+ breast cancer patients. However, the drug also has known cardiotoxic side effects through mechanisms that are not fully understood. Here we utilized human induced pluripotent stem cell-derived cardiomyocytes (iPS-CMs) to model trastuzumab-related cardiotoxicity in vitro. We demonstrate that cardiotoxic effects of ErbB2 inhibition by trastuzumab can be recapitulated only ...
