Rituximab (Rituxan) is more effective and has lower rates of discontinuation than other disease-modifying treatments in newly diagnosed patients with relapsing-remitting multiple sclerosis, according to a Swedish study published online in the January 8, 2018, issue of JAMA Neurology.

Intravitreal injection of bevacizumab (Avastin) has revolutionized the treatment of diabetic eye disease, and has emerged as an important treatment modality, either as primary or adjuvant therapy for diabetic macular edema and proliferative diabetic retinopathy.

While the European experience with biosimilars is one of significant uptake of biosimilars, individual European nations have had distinctly different levels of uptake. These differences are largely due to local variation in pricing and reimbursement, education levels, population characteristics, and stakeholder incentives.

The Center for Biosimilars recaps the top 5 biosimilars articles for the week of January 1, 2018.

Patients with renal anemia undergoing hemodialysis who were treated for up to 24 months with the intravenous biosimilar epoetin alfa HX575 (Binocrit) showed hemoglobin outcomes equivalent to reference epoetin alfa.

A new study used flow cytometry to compare phosphorylation levels of intracellular epitopes in peripheral blood mononuclear cells from patients with psoriasis in clinical remission who were treated with reference infliximab versus healthy controls, and further evaluated whether a switch from reference infliximab to biosimilar CT-P13 affected intracellular phosphorylation patterns.

Bevacizumab is employed cautiously in patients with multifocal glioblastomas rather than single glioblastomas because of a fear, based on unconfirmed preclinical data, that bevacizumab can increase the invasive tumor phenotype.

As the treatment paradigm in inflammatory bowel disease (IBD) has shifted from controlling symptoms to fully controlling disease in order to prevent organ damage and disability, some have argued that disability is a better, more objective measure than quality of life in clinical trials and population studies of IBD.

Adalimumab demonstrated efficacy and safety in the treatment of patients with moderate to severe ulcerative colitis (UC) in the first Brazilian study to demonstrate the effectiveness and safety profile of the therapy in patients with UC.

Antidrug antibodies (ADAs) are commonly found in healthy subjects after a single intravenous dose of infliximab and result in faster clearance of infliximab, shorter elimination time, and lower serum infliximab levels, according to a study published in the September 2017 issue of Drugs in R&D by Eli D. Ehrenpreis, MD.

In clinical practice, biologics are routinely used for medically accepted off-label indications, and these uses are typically curated by guidelines. A newly published study, led by Edward Li, PharmD, MPH, BCOP, argues that the FDA’s framework for granting the extrapolation of indications for biosimilars can be used by clinicians and payers to determine appropriate off-label uses of biosimilars.

According to Marcus Snow, MD, assistant professor of internal medicine in the division of rheumatology, University of Nebraska Medical Center, some of the most critical developments in the biosimilars space during 2017 were the result of payer decisions.

Paul P. Doghramji, MD, FAAFP discusses using biosimilars in practice.

2017 brought a number of notable guests to The Center for Biosimilars®. Here are the most-watched interviews of the year.

While more biosimilars gained regulatory approval 2017 and neared their entry into the US marketplace, physician acceptance of these products proved to be a challenge.

The Center for Biosimilars recaps the the top 5 articles for the week of December 18, 2017.

Biologics are the most expensive drug category in the United States. A recent study, published in the Journal of Managed Care and Specialty Pharmacy, investigated how American health systems are reacting to the introduction of biosimilars into the marketplace, and described real-world implementation strategies.

AbbVie reported on Wednesday that a phase 3 trial of its upadacitinib as monotherapy for rheumatoid arthritis (RA) met all of its primary and key secondary endpoints, giving more momentum to the drug that appears poised to help AbbVie retain its share of the RA market after adalimumab biosimilars launch in the United States. However, a death reported during the trial raises renewed concerns about the safety of the Janus kinase inhibitor.

Fresenius Kabi, a subsidiary of the German-based Fresenius SE and Co. KFaA, announced yesterday that its Marketing Authorization Application for MSB11022, an adalimumab (Humira) biosimilar candidate, was submitted and accepted for review by the European Medicines Agency (EMA).

Frank Dellanna, MD, and colleagues reviewed the journey of HX575 from development to approval in Europe, and describe a decade of clinical experience in patients with CKD, as the history and experience with this biosimilar provides an excellent example of a successful demonstration of biosimilarity.

The Center for Biosimilars® recaps the top 5 articles for the week of December 11.

A recently published study explored the impact of 2 different initial doses and a cumulative 2-year dose of rituximab on drug adherence and predictors of adherence to treatment in patients with RA in an observational clinical setting.

A significant proportion of patients with Crohn disease (CD) who initially respond to infliximab therapy experience secondary loss of response with symptom flares. Treatment intensification (using increases in dose, dose frequency, or a combination of both to implement intensification) is a suggested strategy for regaining response.

Roche has announced positive data on 2 of its innovator oncology biologics in combination with other therapies. The combinations using rituximab (MabThera, Rituxan) and bevacizumab (Avastin) could help the Swiss drug maker to protect sales of these monoclonal antibodies in the face of oncoming biosimilar competition.

A recent study examined whether the use of the anti–tumor necrosis factor agent infliximab could reduce the death of photoreceptors after retinal detachment in an experimental mouse model.

A recently published systematic literature review sought to compare the effects of down-titration of biologics compared with standard dosing on clinical efficacy and health-related quality of life, and to evaluate the impact of decreased doses on the cost of RA treatment.

The Center for Biosimilars recaps the top 5 articles for the week of December 4.

Advances in research have led to increased therapeutic options for patients with cancer, but these drugs come at a substantial cost; high out-of-pocket costs pose a significant barrier to treatment initiation for patients with cancer, according to a new, retrospective claims-based study.

No differences in drug levels or disease activity were found when adult patients with inflammatory bowel disease (IBD) were switched from originator infliximab (Remicade) to a biosimilar infliximab (Inflectra) as part of routine care, according to the results of a Dutch study.

A newly published study finds that subcutaneous administration of trastuzumab produces substantial time savings for healthcare providers and patients, as well as reduced costs.
