Dr. Bryce’s responsibilities will be assumed by the members of the Company’s clinical development team and clinical sciences team.

The Company thanks Dr. Bryce for his time at Puma and wishes him well in his new position as the Chief Medical Officer of a biotechnology company that is developing drugs for the treatment of cancer.

The Company continues to anticipate the following key milestones: (i) completing enrollment in the randomized cohort in the Phase II SUMMIT trial of neratinib in hormone receptor positive breast cancer that has a HER2 mutation in the second quarter of 2021; (ii) reporting top line data from the randomized cohort in the Phase II SUMMIT trial of neratinib in hormone receptor positive breast cancer that has a HER2 mutation in 2021; (iii) conducting a pre-NDA meeting with the U.S. Food and Drug Administration (the “FDA”) to discuss accelerated approval of neratinib in HER2-mutated hormone receptor positive breast cancer and HER2-mutated cervical cancer in 2021; (iv) reporting Phase II data from the SUMMIT trial of neratinib in non-small cell lung cancer patients with epidermal growth factor receptor (“EGFR”) exon 18 mutations in the second half of 2021; (v) reporting data from the Phase II TBCRC-022 trial of the combination of Kadcyla plus neratinib in patients with HER2-positive breast cancer with brain metastases who have previously been treated with Kadcyla in the second half of 2021; (vi) conducting a meeting with the FDA to discuss the potential for an accelerated approval pathway for neratinib in non-small cell lung cancer patients with EGFR exon 18 mutations who have been previously treated with an EGFR tyrosine kinase inhibitor in 2021; and (vii) receiving regulatory decisions for the extended adjuvant HER2-positive early stage breast cancer indication in additional countries in 2021.
