Teva and Celltrion have launched their Herzuma trastuzumab biosimilar in the US at a 10% discount to the Herceptin brand. The discount matches that offered for their Truxima rituximab biosimilar and compares to steeper discounts offered by competing biosimilars.

Mylan and Biocon's global development alliance has so far led to two biosimilar launches in the US. A filing for a biosimilar of Genentech's Avastin (bevacizumab) submitted by Mylan may soon bring a third.

Mylan says its ‘durable’ business model has helped it to withstand pressures from adverse industry trends in 2019, boosted by $1bn in sales from newly-launched products. However, negative currency effects cut the firm’s sales growth from 3% at constant currencies to 1% as reported.
