Mer­ck­'s melanoma drug shows ear­ly promise for re­sis­tant can­cers in PhI tri­al

Ear­ly news on a Mer­ck drug can­di­date has re­searchers hope­ful that the in­ves­ti­ga­tion­al ther­a­py could be used to fight drug re­sis­tant can­cers. The da­ta is ear­ly — and on a very small pa­tient group — but re­searchers say the drug’s per­for­mance match­es ini­tial re­sponse rates to ap­proved treat­ments like MEK in­hibitors.

The treat­ment, called MK-8353, was test­ed in pa­tients with melanoma and oth­er can­cers with mu­ta­tions in the BRAF or RAS genes. The drug was de­signed to block the ERK sig­nal, which has been shown to help dri­ve can­cer cell growth in re­sis­tant melanoma and oth­er dis­eases.
