Interim data from the Phase II CONTROL Trial showed that the addition of prophylactic treatment with loperamide plus budesonide reduced the rate of discontinuation due to neratinib-associated diarrhea to 11% versus a discontinuation rate of 18% with loperamide alone.
LOS ANGELES, CA, USA I October 02, 2019 I Puma Biotechnology, Inc. (NASDAQ: PBYI) announced that the U.S. Food and Drug Administration (FDA) has approved a labeling supplement for NERLYNX® (neratinib) for the extended adjuvant treatment of HER2-positive early stage breast cancer. With the approval of the labeling supplement, the label now includes safety information based on interim results from Puma’s Phase II CONTROL Trial, a study evaluating antidiarrheal prophylaxis or dose escalation in the reduction of neratinib-associated diarrhea that has a primary endpoint of the incidence of grade 3 or higher diarrhea. Interim data from the trial showed that the addition of prophylactic treatment with loperamide plus budesonide reduced the discontinuation rate due to neratinib-associated diarrhea to 11% versus a discontinuation rate of 18% with loperamide alone.
In the ongoing CONTROL Trial, patients with HER2-positive early stage breast cancer who have completed trastuzumab-based adjuvant therapy receive neratinib daily for a period of one year. The trial initially tested high dose loperamide prophylaxis given for the first 2 cycles (56 days) of treatment (12 mg on days 1-14, 8 mg on days 15-56 and as needed thereafter). The CONTROL Trial (NCT02400476) was then expanded to include four additional cohorts. One cohort received the combination of loperamide and budesonide. For the 64 patients who received the combination of loperamide plus budesonide, the incidence of grade 3 diarrhea was 28% compared to 32% in patients treated with loperamide alone. Diarrhea leading to treatment discontinuation declined to 11% in the loperamide plus budesonide cohort, compared to 18% in the loperamide alone cohort.
“We are pleased to be able to update the label for NERLYNX to include the data on the use of prophylactic loperamide plus budesonide,” said Alan H. Auerbach, Chief Executive Officer and President of Puma Biotechnology. “We believe FDA approval of the labeling supplement will help us to ensure that physicians and patients are better informed in selecting prophylactic therapy that may improve the tolerability of the drug.”
Neratinib was approved by the U.S. Food and Drug Administration (FDA) in July 2017 for the extended adjuvant treatment of adult patients with early stage HER2-positive breast cancer following adjuvant trastuzumab-based therapy and is marketed in the United States as NERLYNX® (neratinib) tablets.
About HER2-Positive Breast Cancer
Approximately 20 to 25 percent of breast cancer tumors over-express the HER2 protein. HER2-positive breast cancer is often more aggressive than other types of breast cancer, increasing the risk of disease progression and death. Although research has shown that trastuzumab can reduce the risk of early stage HER2-positive breast cancer returning after surgery, up to 25% of patients treated with trastuzumab experience recurrence.

Puma Biotechnology, Inc. is a biopharmaceutical company with a focus on the development and commercialization of innovative products to enhance cancer care. Puma in-licenses the global development and commercialization rights to three drug candidates — PB272 (neratinib, oral), PB272 (neratinib, intravenous) and PB357. Neratinib, oral was approved by the U.S. Food and Drug Administration in July 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. NERLYNX was granted marketing authorization by the European Commission in September 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.
