Nanobiotix (+10%): according to La Lettre, Johnson & Johnson is reportedly considering a takeover of the French biotech firm, for which it is already a development partner. 

Grifols (+6%): the Spanish blood plasma specialist is surging following the announcement of an IPO for a minority stake in its U.S. biopharmaceutical division.
