Regulators in China have approved the country’s first ever biosimilar, a rituximab product referencing Rituxan. The product, HLX01, was developed by Henlius and will be primarily used in the treatment of non-Hodgkin lymphoma. Regulatory requirements that were applied in the analysis of the drug, say investigators who took part in its development, will set a precedent for analytical similarity assessments of biosimilars in China going forward.

A newly published study discussed the potential for the anti–vascular endothelial growth factor agent bevacizumab (Avastin) and its cost-saving biosimilars to be used as second-line therapy for the treatment of patients with advanced hepatocellular carcinoma (HCC) who progressed while receiving standard therapy.

The United Kingdom’s National Institute for Health and Care Excellence (NICE) today released a final appraisal of pertuzumab (Perjeta) together with intravenous trastuzumab and chemotherapy for the treatment of HER2-positive early breast cancer, and recommended pertuzumab for use in patients if they have lymph node–positive disease and if drug maker Roche adheres to its promised discount for the drug.

Results from the phase 3 REFLECTIONS B327-02 study in patients with HER2-positive metastatic breast cancer (MBC) were first presented in abstract form, but have now been reported in detail.

The assumption that Medicare Part B payment rates lead providers to create higher drug utilization for costlier treatments in order to benefit from larger add-on payments is not correct, a recent white paper said. The paper from Xcenda, a part of AmerisourceBergen, also found similar results when looking at physician-administered drugs in the hospital outpatient setting.

Innovent Biologics, a China-based biopharmaceutical company, recently submitted a New Drug Application for its proposed bevacizumab biosimilar, IBI-305, referencing Avastin, to the Chinese regulatory agency, the National Medical Products Administration.

While a majority of survey respondents said that they were at least somewhat familiar with current developments in oncology biosimilars, analyses of open-ended definitions found that only 1 participant could fully define a biosimilar, according to researchers.

Drug makers often point to substantial research and development (R&D) costs as reasons for the high prices of innovator drugs, particularly in oncology. However, some stakeholders have expressed skepticism about whether R&D costs are indeed in line with the prices that drug makers charge. In a new study published in JAMA, investigators sought to compare sales of cancer drugs with estimated R&D costs.

The FDA has approved Samsung Bioepis’ Ontruzant (trastuzumab-dttb), a biosimilar trastuzumab referencing Herceptin, for the treatment of HER2-positive breast cancer and HER2 overexpressing gastric cancer.

This week, investigators published the results of the MAPLE study, a phase 3 trial of Amgen’s bevacizumab in comparison with the reference, Avastin, in patients with advance nonsquamous non–small cell lung cancer who were also receiving first-line chemotherapy with carboplatin and paclitaxel.

The Community Oncology Alliance (COA) recently formed a standing Biosimilars Committee for which The Center for Biosimilars® advisory board member, Kashyap Patel, MD, a practicing medical oncologist at Carolina Blood and Cancer Care in South Carolina, was named chair alongside co-chairs immediate past president of COA, Jeff Vacirca MD, FACP, and Michael Diaz, MD, incoming COA president.

Coherus BioSciences has confirmed that it has launched its pegfilgrastim biosimilar, Udenyca, in the United States market.

Researchers found a $2522 mean cost for biosimilar and follow-on filgrastim versus a $2516 mean cost for reference filgrastim.

Germ cell tumors are common malignancies, and chemotherapy with a regimen of bleomycin, etoposide, and cisplatin (BEP) has improved the prognosis for patients with these tumors. However, BEP involves significant myelosuppression, and the safety of pegfilgrastim for the prevention of febrile neutropenia related to myelosuppression has not been well investigated in patients with this tumor type.

A recent study evaluated the impact of adding bevacizumab to chemotherapy treatment for patients who were newly diagnosed with ovarian cancer. The results, published in Gynecologic Oncology, found that while the addition of bevacizumab greatly improved progression-free survival (PFS), it did not improve overall survival.

A recent study sought to investigate the overall survival (OS) advantage of the addition of trastuzumab to chemotherapy for patients with human epidermal growth factor 2-positive early breast cancer.

During the European Society for Medical Oncology’s Asia 2018 annual meeting, held in Singapore from November 23 to November 25, a research team presented an update on the clinical program for HLX02, a proposed trastuzumab biosimilar referencing Herceptin. The proposed biosimilar is being developed by the Chinese firm Shanghai Henlius Biotech.

Beth Wittmer, RN, OCN, senior manager of care management at Florida Cancer Specialists, addresses how nurses are being educated about biosimilars.

During last month’s European Society for Medical Oncology Asia 2018 annual meeting, held in Singapore from November 23 to November 25, researchers presented data demonstrating the biosimilarity of QL1101 with reference bevacizumab (Avastin).

Mylan and Biocon have received final approval from the European Commission to market their trastuzumab biosimilar, Ogivri, referencing Herceptin.

Chinese biologics developer Innovent has announced that its proposed bevacizumab candidate, IBI305, has met its primary end points in 2 randomized, head-to-head clinical trials that compared the biosimilar to the brand-name bevacizumab (Avastin).

Since the advent of biosimilar filgrastim, patient access to the prophylaxis of chemotherapy-induced febrile neutropenia has improved in many regulatory territories, yet concerns remain about whether the United States is keeping pace with the rest of the world in biosimilar uptake and associated patient access.

Samsung Bioepis has announced that a 1-year follow-up study comparing event-free survival in patients treated with SB3, a biosimilar trastuzumab (approved in Europe as Ontruzant) showed that the biosimilar has similar safety and efficacy profiles to the reference Herceptin.

There are several options for the prophylaxis of febrile neutropenia (FN), including pegfilgrastim delivered in an on-body injector (OBI), a single injection of pegfilgrastim, and daily injections with reference filgrastim or Sandoz’ biosimilar filgrastim.

The launch of biosimilar rituximab is an eagerly awaited event among US healthcare stakeholders who are cognizant of the high cost of intravenously (IV) administered rituximab in treating non-Hodgkin lymphoma (NHL). At the same time, another innovation in rituximab delivery—a subcutaneously administered rituximab formulation—has the potential to save both cost and time.

The study’s authors concluded that, at the median follow-up of 23 months, the data demonstrated comparable progression-free survival, sustained response, and overall survival between both the biosimilar and the reference product.

For health systems like the Veterans Health Administration (VHA), where controlling costs while providing high-quality care is of heightened concern, achieving the best value for money in the prophylaxis of neutropenia can help to control the cost of cancer care.

Celltrion’s CT-P10, a biosimilar rituximab that was FDA approved under the brand name Truxima in November 2018, is already in wide use for a host of indications in many regulatory territories. During this week’s 60th Annual Meeting and Exposition of the American Society of Hematology in San Diego, California, multiple research teams are reporting data that underscore the safety and efficacy of CT-P10 in hematological conditions.

In 2016, the Saskatchewan Cancer Agency switched from the brand-name filgrastim, Neupogen, to a biosimilar, Apotex’s Grastofil, for stem cell mobilization prior to autologous stem cell transplants. In a study presented at the American Society of Hematology’s Annual Meeting, researchers sought to determine the safety and efficacy of using a biosimilar for this setting.

Patients who are candidates for hematopoietic stem cell transplantation (AHSCT) require adequate collection of stem cells, and granulocyte colony-stimulating factor agents (G-CSFs) are typically used for stem cell mobilization while plerixafor is used to increase the yield of mobilized stem cells. While the biosimilar filgrastim agent Zarxio has become a more widely used, cost-saving G-CSF option in this context, little research has been conducted on whether the use of the biosimilar rather than its reference, Neupogen, has an impact on plerixafor use in patients undergoing AHSCT.
