Glaxo joins the Covid-19 delay queue

Glaxosmithkline will have to wait a little longer to find out whether dostarlimab can become the industry’s seventh anti-PD-(L)1 antibody to reach the market. A US Pdufa date in the second half of 2020 came and went with no statement from the company, but it now emerges that the Covid-19 pandemic is to blame for the delay. A Glaxo spokesperson told Evaluate Vantage that approval “requires a site inspection of our manufacturing site, the timing of which is contingent on Covid-19 travel restrictions. The site inspection has not occurred yet, so we are now expecting approval in the first half of 2021.” For now Glaxo is not mounting a strong challenge to the leaders, and its filing seeks approval in MSS or MSI-high endometrial cancer, a relatively obscure use in which only Keytruda’s label in MSI-high cancers irrespective of tumour type has an overlap.
