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).

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.

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.

November saw a number of developments related to biosimilar therapies for rheumatologic indications, with new data published, policies adapted, and devices launched.

A recent study was conducted to determine whether the concurrent use of denosumab with a biologic disease-modifying antirheumatic drug (bDMARD), such as adalimuab, etanercept, or infliximab, increases the risk of infection.

Biologics are increasingly used in the treatment of inflammatory bowel disease (IBD), but real-world data quantifying the costs of these therapies have been lacking. A new study, published in Alimentary Pharmacology and Therapeutics, sought to determine trends in costs and relative market share of IBD therapies in the United States over the past 9 years.

Janssen-Cilag International’s biologic drug guselkumab (Tremfya) has received approval from the European Commission (EC) for the treatment of adults with moderate to severe plaque psoriasis who are candidates for systemic therapy.
