The body of evidence demonstrating the safety and efficacy of biosimilar infliximab, CT-P13 (Inflectra, Remsima), is growing, particularly in the extrapolated indication of inflammatory bowel disease (IBD). This month saw the publication of 2 new studies that provided reassuring data on CT-P13, one of which focused on switching pediatric patients with IBD to CT-P13, and the second of which explored switching to the reference infliximab from the biosimilar in adults with IBD.

Biosimilar developer Celltrion has seen strong success with its biosimilar infliximab, CT-P13, which is marketed in the United States as Inflectra and in other territories as Remsima. This week, the company said that its product has captured 56% of the infliximab market in Europe as of the third quarter of 2018.

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.

During the 37th annual J.P. Morgan Healthcare Conference held January 7-10 in San Francisco, California, drug makers Mylan and Momenta explained the role that biosimilars will play in their growth, while AbbVie outlined its strategy for managing direct biosimilar competition.

The second day of the 37th Annual J.P. Morgan Healthcare Conference saw presentations from drug makers Amgen and Sanofi—both of whom produce both innovator products facing biosimilar competition as well as biosimilars of competitors’ products—as well as from Alexion, which is defending its flagship product from advancing biosimilar challengers.

While 63% of respondents who had switched to a biosimilar said that they had been consulted in some form prior to the transition, 37% said that they had not been consulted (despite the fact that National Health Service guidelines require the patient to be consulted about such a switch).

During the second day of the 37th Annual J.P. Morgan Healthcare Conference, held January 7-10 in San Francisco, California, Dennis M. Lanfear, president and CEO of Coherus BioSciences, presented an overview of what he called his company’s “branded approach” to selling its newly launched biosimilar pegfilgrastim, Udenyca.

The fact that cost growth is driven largely by older products and not by new blockbuster therapies “is particularly important,” write the authors, “because in the current value-based landscape, increasing drug costs attributable to new products can sometimes be justified on the basis of improved outcomes. However, rising costs due to inflation do not reflect improved value for patients.”

During the first day of the 37th Annual J.P. Morgan Healthcare Conference, held January 7-10 in San Francisco, California, 2 major biosimilar developers gave a look at their strategies for 2019 and beyond.

This week, the United Kingdom’s Medicines and Healthcare products Regulatory Agency (MHRA) issued updated guidance for industry on preparing for the growing likelihood that the United Kingdom will leave the European Union without a trade deal.

A recent letter, published in Alimentary Pharmacology and Therapeutics, reported on early findings from an ongoing, 18-month, multicenter, observational prospective study conducted among the cohort of the Sicilian Network for Inflammatory Bowel Disease (IBD). According to the authors of the letter, these are the first data on SB2 in treating IBD.

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

Biosimilars have the potential to deliver substantial savings to the healthcare system, but only insofar as they are adopted and used in clinical practice. A newly published systematic review evaluated US and European healthcare provider knowledge, perceptions, and prescribing behaviors related to biosimilars, and it found that providers are still taking a cautious approach to biosimilars in part because of a lack of awareness of these medicines.

Chinese drug developer JHL Biotech has announced that it randomized its first patient in a phase 3 study of JHL1101, a proposed biosimilar rituximab referencing Rituxan.

In children, idiopathic nephrotic syndrome (NS) generally responds well to treatment with corticosteroids, but long-term use of steroids in children can produce adverse effects (AEs) such as growth impairment and hypertension. Calcineurin inhibitors, too, are associated with AEs, including toxicity and diabetes. Rituximab has been proposed as an option for difficult-to-treat childhood-onset NS, and a recent study evaluated the efficacy and safety of a single dose of rituximab in this setting.

Biologic drugs can effectively treat inflammatory bowel disease (IBD), but the cost of these products can be prohibitive. Biosimilars such as CT-P13 (Remsima, Inflectra), an infliximab biosimilar referencing Remicade, have the potential to drive down treatment costs and enhance access to biologics for the patients who need them.

On the heels of the FDA approval of Celltrion’s rituximab biosimilar Truxima in November 2018, December saw the publication of a variety of new data on biosimilars used in hematology.

Despite the fact that the World Health Organization classifies insulin as an essential medicine that should be available at all times at a price that patients can afford, US insulin prices have continued to climb in recent years.

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 systematic review of the literature reported on randomized controlled trials and nonrandomized studies on the use of granulocyte colony-stimulating factor therapies (G-CSFs) to reduce the incidence of febrile neutropenia, and found that short- and long-acting therapies, when dosed according to guidelines, have little difference in their efficacy.

Drugs that treat rare diseases are granted various incentives under the Orphan Drug Act of 1983 if they meet criteria related to the size of the rare disease population (under 200,000 people) that can be effectively treated by the drug in question. The Government Accountability Office (GAO) recently issued a report that finds serious deficiencies with the ways in which the Orphan Drug Act is administered by the FDA.

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).

CreakyJoints, a patient organization that is part of the Global Healthy Living Foundation (GHLF), has released the first edition of its patient guide to biosimilar medicines.

Sandoz has entered into an agreement with Chinese drug maker Gan and Lee to commercialize biosimilar insulins to treat patients with type 1 and type 2 diabetes.

While many stakeholders are concerned most immediately about how a recent ruling on the Affordable Care Act (ACA) could affect US patients’ healthcare options and coverage for pre-existing conditions, the biosimilars industry is also concerned about the future of one key feature of the ACA that keenly impacts the biosimilars landscape: the Biologics Price Competition and Innovation Act.

Last week, Republicans in the House of Representatives and in the Senate introduced legislation that would restrict generic and biosimilar developers from challenging patents on reference drugs using the inter partes review (IPR) process.

On Friday, Pfizer announced that the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion of its proposed bevacizumab biosimilar, PF-06439535, to be marketed under the trade name Zirabev.

The authors concluded that in their analysis of real-world data, the effectiveness of the biosimilar was equivalent to that of the reference product in patients with Crohn disease (CD) who were naïve to therapy with infliximab, and no difference was observed in terms of safety between the 2 therapies.

The FDA has approved Celltrion and Teva’s Herzuma (trastuzumab-pkrb), a biosimilar trastuzumab referencing Herceptin, for the treatment of HER2-positive breast cancer.

Second-generation anti–tumor necrosis factor (TNF) agents, etanercept, certolizumab, and golimumab, demonstrated a stronger neutralizing effect toward TNF versus first-generation anti-TNF agents, infliximab and adalimumab.
