DUBLIN – Last May, a quartet of Dutch biotech industry veterans gathered for a socially distanced outdoor meeting in a private garden in Leiden to discuss what could be done to prevent the present COVID-19 fiasco from ever occurring on such a scale again. A new startup, Leyden Laboratories BV, emerged from that conversation, and it has just raised €40 million (US$47.3 million) in a series A round to develop broad-spectrum, self-administered, intranasal antiviral drugs to prevent infection.
