Hesham Abdullah, Senior Vice President, Global Head Oncology R&D, GSK, said: “This acquisition adds to GSK’s growing pipeline of targeted therapeutics for cancers originating in the gastrointestinal tract. We plan to advance IDRX-42 for second line treatment of gastrointestinal stromal tumours, where there are no approved treatments to effectively address all resistance mutations, and accelerate development in an earlier setting.”
