Polyphor announces enrollment of first patient in FORTRESS Phase III clinical trial for balixafortide in combination with eribulin in patients with metastatic breast cancer
Balixafortide is the most advanced and only CXCR4 antagonist in development in a pivotal Oncology global registration trial.
Polyphor today announced the enrollment of the first patient in its FORTRESS clinical trial, the pivotal Phase III study evaluating balixafortide (POL6326) in combination with eribulin for the treatment of patients with HER2 negative, locally recurrent or metastatic breast cancer (MBC). Balixafortide is the only CXCR4 antagonist in development for breast cancer and is the most advanced CXCR4 antagonist being developed in solid tumors.
"The enrollment of the first patient in our Phase III clinical study is a significant step forward for the development of balixafortide. There is a significant unmet need for new treatment options for women with metastatic breast cancer who have failed initial standard-of-care chemotherapies. Developing a new treatment option will provide new hope for women with this devastating disease," said Giacomo Di Nepi, Chief Executive Officer of Polyphor. "We are hopeful that the response rates seen in our proof-of-concept study can be replicated in the FORTRESS trial and that balixafortide can make a positive impact on patient outcomes."
FORTRESS (POL6326-009) is an international, multicenter, randomized active-controlled, open-label Phase III trial which will investigate the efficacy, safety and tolerability of intravenous balixafortide given with eribulin versus eribulin alone in the treatment of HER2 negative, locally recurrent or metastatic breast cancer. The study will comprise a total of 384 patients with HER2 negative MBC, of which 320 patients receiving third or subsequent line and 64 patients receiving second line chemotherapy. Subject to the data Polyphor will have the possibility to submit a filing for accelerated approval approximately six months after the recruitment is completed on the basis of the analysis of the overall response rate (ORR), confirmed by an independent blinded review, and of the associated durability of response. The full approval would be based on the magnitude of Progression Free Survival (PFS) on blinded independent review, supported by an overall survival trend favoring balixafortide arm and a favorable risk-benefit profile.

Balixafortide is being developed to improve therapy outcomes in cancer, when used in combination with other agents. Balixafortide is the only CXCR4 antagonist in development for breast cancer and is the most advanced CXCR4 antagonist, being developed in solid tumors, being the first product candidate to reach proof of concept. The molecule was discovered based on Polyphor's proprietary macrocycle technology platform. Balixafortide showed strong results in a Phase Ib/proof of concept clinical trial in combination with eribulin in patients affected with advanced metastatic breast cancer. The development path identified with the input of the FDA is to conduct a single pivotal study to achieve approval in HER-2 negative metastatic breast cancer patients who previously received at least two chemotherapeutic regimens in the metastatic setting. Additionally, there is the possibility of achieving an accelerated approval based on interim results. Polyphor is also conducting preclinical work to establish the potential for balixafortide in combination with other drugs and in other oncology indications.
