Pharmaceutical US biotech Gilead Sciences stepped further into the immuno-oncology arena last week, announcing a $4.9 billion acquisition of Forty Seven Inc and its candidate magrolimab.

There was much reporting of developments on the novel coronavirus COVID-19, with Japan’s Takeda announcing a different approach to tackling the epidemic with plasma-based therapies via a candidate vaccine dubbed TAK-888. Also regarding research, there was disappointment for AstraZeneca, when its immune-oncology drug Imfinzi failed endpoints in a Phase III bladder cancer drug. 8 March 2020
