Paratek shares soar as the an­tibi­ot­ic de­vel­op­er posts a ‘for sale’ sign

Shares of Paratek Phar­ma­ceu­ti­cals $PRTK shot up more than 30% Wednes­day morn­ing af­ter Bloomberg post­ed a sto­ry say­ing that the biotech had put it­self up on the auc­tion block, ex­plor­ing a sale amid takeover in­ter­est as it nears a reg­u­la­to­ry pitch for a new an­tibi­ot­ic.

Just a few weeks ago Paratek her­ald­ed its third straight pos­i­tive study for oral omada­cy­cline, which lined up nice­ly as a non-in­fe­ri­or al­ter­na­tive to line­zol­id. Re­searchers did have to re­port that the Paratek an­tibi­ot­ic spurred prob­lems with a high­er rate of nau­sea and vom­it­ing, but ex­ecs felt the dif­fer­ence wasn’t big enough to mar its chances as physi­cians look for new weapons in the war against drug-re­sis­tant, com­mu­ni­ty-ac­quired in­fec­tions.
