“A decade ago, researchers believed molecular alterations occurred in only one or two cancer types. That way of thinking has changed, however, with the understanding that the same alterations, especially gene fusions, can occur across many different tumor types.
“As a result, researchers have designed a recently launched clinical study into entrectinib, a first-inclass inhibitor of tropomyosin receptor kinases (Trk), as a basket trial in which the drug can be evaluated simultaneously for activity against three gene alterations and multiple tumor types.
“STARTRK-2 (NCT02568267) is an open-label, phase II study in which patients with locally advanced or metastatic solid tumors are assigned to different baskets according to whether their tumors harbor rearrangements in one of three key genes—NTRK1/2/3, ROS1, or ALK.”
