Insights+ Key Biosimilars Events of July 2019
Biosimilars are key alternatives for costly Biologics therapies and saving million dollars of patients in multiple diseases. Hence physicians are likely to adopt biosimilars 'a reference product to biologics' which are biologically like biologics. They possess similar therapeutic properties in terms of potency, safety, and efficacy to original biologic products. Our team at PharmaShots have summarized key events of biosimilar space in month of July 2019.

Date - July 22, 2019
Product - Denosumab, Biosimilar
The P-I/III ROSALIA study involves assessing of biosimilar denosumab vs reference product in 520 postmenopausal patients with osteoporosis for 52 wks. following re-randomization of patients receiving the reference therapy to either continue with a third dose or transition to biosimilar denosumab until @78wks. The aim of the study is to match bio similarity data with the reference product with 1EPs as a percentage change in lumbar spine bone mineral density and the results are expected to support regulatory submissions. Denosumab is a mAb targeting RANKL protein which decreases the production and activity of osteoclasts, resulting in a reduction of bone loss, fracture and other bone complications.
