PUMA BIOTECHNOLOGY, INC. (NASDAQ:PBYI) Files An 8-K Other Events
Item 8.01 Other Events.

On January 6, 2017, Puma Biotechnology, Inc. (the “Company”) announced that it expanded the fourth cohort from its Phase II SUMMIT clinical trial of its lead drug candidate PB272 (neratinib) as a single agent in patients with solid tumors who have an activating HER2 mutation (basket trial). The cohort that has been expanded is the cohort that includes patients with metastatic cervical cancer and whose tumors have a HER2 mutation.

The Phase II SUMMIT basket trial is an open-label, multicenter, multi-histology, international study to evaluate the safety and efficacy of PB272 administered daily to patients who have solid tumors with activating ERBB mutations including EGFR, HER2 and HER3. The cohorts included in the basket study receiving neratinib monotherapy are hormone receptor-negative breast cancer; biliary tract cancers; endometrial cancer; gastric/esophageal cancer; ovarian cancer; and all other solid tumors with a HER2 mutation. The cohorts receiving combination treatment are hormone receptor-positive breast cancer (neratinib plus fulvestrant) and bladder cancer (neratinib plus paclitaxel). The cervical cancer patients initially entered the study in the “other solid tumors with a HER2 mutation” cohort, and due to the preliminary activity seen in the trial, the Company has expanded a separate cervical cancer cohort to the protocol for the trial. The expanded HER2-mutant cervical cancer cohort will now enroll a total of 18 patients. The Company expects to present the full results from the SUMMIT study in 2017.
