Patent Claim Scope and Biosimilar Competition in the US and EU.

The US has found it hard to establish competition in the market for biologics, which are therapeutics derived from living cells. In the case of small-molecule drugs, the emergence of direct competition from generic drugs at the end of the exclusivity period has provided the impetus for price competition, leading to lower spending. In 2010, to spur competition in the biologics market, Congress created a simplified pathway for the US Food and Drug Administration (FDA) to approve comparable versions of biologic drugs called biosimilars.

AI and biosecurity: The need for governance.

Governments should evaluate advanced models and if needed impose safety measures.

Comparing the Real-World and Clinical Trial Bleeding Rates Associated with Oral Anticoagulation Treatment for Atrial Fibrillation.

The prevention of stroke in patients with atrial fibrillation (AF) involves the use of oral anticoagulation, commonly in the form of direct oral anticoagulants (DOACs). However, it comes with an increased risk of bleeding, and therefore, counselling patients on their individual risks is important. Although the majority of patients initiated on DOACs have been represented within the clinical trials, some cohorts are under-represented in whom clinicians cannot practice evidence-based medicine.

One versus three weeks hypofractionated whole breast radiotherapy for early breast cancer treatment: the FAST-Forward phase III RCT.

Background: FAST-Forward aimed to identify a 5-fraction schedule of adjuvant radiotherapy delivered in 1 week that was non-inferior in terms of local cancer control and as safe as the standard 15-fraction regimen after primary surgery for early breast cancer. Published acute toxicity and 5-year results are presented here with other aspects of the trial.

Design: Multicentre phase III non-inferiority trial.
