LOS ANGELES--(BUSINESS WIRE)--Puma Biotechnology, Inc. (NASDAQ: PBYI), a biopharmaceutical company, announced that the National Comprehensive Cancer Network (NCCN) Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for Cervical Cancer were updated to include an addition involving neratinib (NERLYNX®).
The updated NCCN Practice Guidelines for Cervical Cancer include neratinib monotherapy for use as second-line or subsequent therapy for recurrent or metastatic disease as an option for patients with HER2-mutated tumors with a designation of Category 2A. The NCCN Guidelines Category of Preference is designated as “useful in certain circumstances” as a treatment option for patients with HER2-mutated tumors.
This addition was based on results from the Phase II SUMMIT trial (NCT01953926), which enrolled a cohort of patients who were required to have histologically confirmed recurrent/metastatic cervical cancer for which no curative treatment existed, along with documented evidence of a somatic, activating HER2 mutation (Friedman CF, D'Souza A, Bello Roufai D, et al. Targeting HER2-mutant metastatic cervical cancer with neratinib: Final results from the Phase II SUMMIT basket trial. Gynecol Oncol. 2024;181:162-169. doi: 10.1016/j.ygyno.2023.12.004).
Alan H. Auerbach, Chief Executive Officer and President of Puma, said, “We are pleased with the additional inclusion of neratinib in the NCCN Guidelines for Cervical Cancer for patients with HER2 activating mutations. Physicians use the NCCN Guidelines as the standard resource for determining the best course of treatment for patients. We believe the updated NCCN guidelines will increase awareness, which will help assist patients, their caregivers and their healthcare providers in making informed decisions while treating this significant unmet need in advanced cervical cancer.”
About HER2-Mutated Cervical Cancer
Despite recent advancements in the therapeutic landscape for recurrent and metastatic cervical cancer, there is a need to identify robust biomarkers to direct therapy choices to target mutational drivers. Somatic HER2 (ERBB2) mutations have been reported in up to 9% 1,2,3 of cervical cancers and are associated with poor prognosis 1,2. In a recent real-world study, prospective genomic profiling of cervical cancer patients identified HER2 mutations as one of the more prevalent genomic alterations in the studied cervical cancer population3.

About Puma Biotechnology
Puma Biotechnology, Inc. is a biopharmaceutical company with a focus on the development and commercialization of innovative products to enhance cancer care. Puma in-licensed the global development and commercialization rights to PB272 (neratinib, oral), in 2011. Neratinib, oral was approved by the U.S. Food and Drug Administration in 2017 for the extended adjuvant treatment of adult patients with early stage HER2-overexpressed/amplified breast cancer, following adjuvant trastuzumab-based therapy, and is marketed in the United States as NERLYNX® (neratinib) tablets. In February 2020, NERLYNX was also approved by the FDA in combination with capecitabine for the treatment of adult patients with advanced or metastatic HER2-positive breast cancer who have received two or more prior anti-HER2-based regimens in the metastatic setting. NERLYNX was granted marketing authorization by the European Commission in 2018 for the extended adjuvant treatment of adult patients with early stage hormone receptor-positive HER2-overexpressed/amplified breast cancer and who are less than one year from completion of prior adjuvant trastuzumab-based therapy. NERLYNX® is a registered trademark of Puma Biotechnology, Inc.
In September 2022, Puma entered into an exclusive license agreement for the development and commercialization of the anti-cancer drug alisertib, a selective, small molecule, orally administered inhibitor of aurora kinase A. Initially, Puma intends to focus the development of alisertib on the treatment of small cell lung cancer and breast cancer. In February 2024, Puma initiated ALISCA™-Lung1, a Phase II clinical trial of alisertib monotherapy for the treatment of patients with extensive-stage small cell lung cancer. In November 2024, Puma initiated ALISCA™-Breast1, a Phase II clinical trial of alisertib in combination with endocrine therapy for the treatment of patients with HER2-negative, HR-positive metastatic breast cancer.
To help ensure patients have access to NERLYNX, Puma has implemented the Puma Patient Lynx support program to assist patients and healthcare providers with reimbursement support and referrals to resources that can help with financial assistance. More information on the Puma Patient Lynx program can be found at https://www.NERLYNX.com or by dialing 1-855-816-5421.

INDICATIONS
- NERLYNX® (neratinib) tablets, for oral use, is a kinase inhibitor indicated:
- As a single agent, for the extended adjuvant treatment of adult patients with early stage HER2-positive breast cancer, to follow adjuvant trastuzumab-based therapy.
- In combination with capecitabine, for the treatment of adult patients with advanced or metastatic HER2-positive breast cancer, who have received two or more prior anti-HER2 based regimens in the metastatic setting.
Important Safety Information Regarding NERLYNX® (neratinib) U.S. Indication
