Company overview

Commercial Oncology Company

Puma Biotechnology develops and commercializes therapies for breast cancer and other solid tumors. Its business combines the established NERLYNX franchise with clinical development of the Aurora kinase A inhibitor alisertib.

NERLYNX in HER2-Positive Breast Cancer

NERLYNX, or neratinib, is an oral irreversible pan-HER kinase inhibitor. It is approved as extended adjuvant treatment after trastuzumab-based therapy in early-stage HER2-positive breast cancer and with capecitabine in previously treated advanced or metastatic HER2-positive disease.

U.S. Commercial and International Royalty Model

Puma directly markets NERLYNX in the United States and supports access through its Patient Lynx program. International partners commercialize neratinib in other territories, providing Puma with royalty and licensing revenue.

Alisertib Development Program

Alisertib is an oral, selective inhibitor of Aurora kinase A, a protein involved in mitotic progression. Puma licensed global development and commercialization rights and is initially focusing the program on small cell lung cancer and hormone receptor-positive, HER2-negative metastatic breast cancer.

ALISCA Clinical Portfolio

ALISCA-Lung1 evaluates alisertib monotherapy in extensive-stage small cell lung cancer, while ALISCA-Lung2 evaluates alisertib with paclitaxel. ALISCA-Breast1 combines alisertib with endocrine therapy in chemotherapy-naive metastatic breast cancer.

Future catalysts

  • Initiation of enrollment in the ALISCA-Lung2 Phase 1/2 trial in the third quarter of 2026.
  • Enrollment expansion in ALISCA-Lung1 and ALISCA-Breast1 in the second half of 2026.
  • Updated Phase 2 data from ALISCA-Breast1 in the fourth quarter of 2026.
