Zetagen Therapeutics Announces First Patients Enrolled in Phase 2a Clinical Study of ZetaMet™ (Zeta-BC-003) Metastatic Breast Cancer

12 November 2024

400,000 patients annually are diagnosed with metastatic lytic bone lesions with only non- curative, palliative therapies available)

  • ZetaMet™ (Zeta-BC-003) is a first-of-its kind molecular pathway designed to resolve metastatic cancer lesions, inhibit pain, and regenerate bone
  • Phase 2a study examines the safety and efficacy of ZetaMet™ (Zeta-BC-003) for the treatment of metastatic bone lesions to the spine in Stage 4 breast cancer patients
  • ZetaMet™ (Zeta-BC-003) has the potential to be a curative treatment, without systemic limitations, for metastatic lytic breast cancer lesions to bone

November 12, 2024, (Syracuse, New York) – Zetagen Therapeutics, Inc., a private, clinical stage, biopharmaceutical company focused on developing breakthrough therapies, via local administration, for metastatic breast cancer to bone and soft tissues, announced today that the first two patients have enrolled in the phase 2a study, which will evaluate ZetaMet™ (Zeta-BC-003) in the treatment of spinal metastatic lytic breast cancer lesions (ClinicalTrials.gov #NCT05280067).

"Our discovery is the first of its kind with the potential to be a curative therapy for this high unmet need," stated Joe C. Loy, CEO of Zetagen. "Our vision is to deliver breakthrough therapies to all individuals affected by metastatic breast cancer, offering them pain relief, a higher quality of life, while increasing survival rates. The commencement of this study represents a major milestone in the development of ZetaMet™(Zeta-BC-003) and brings us closer to turning our vision into reality.”

The 26-week study, conducted at the University of British Columbia, (UBC) Vancouver, BC, Canada, will evaluate the safety and efficacy of ZetaMet™ (Zeta-BC-003) in treating vertebral bone defects created by lytic metastatic breast cancer. The study will measure the reduction of skeletal related events (SRE), pain, change in vertebral body defect size, and postoperative prescription opioid use.

ZetaMet™ (Zeta-BC-003)

ZetaMet™ (Zeta-BC-003) is a synthetic, small-molecule, delivered via a proprietary controlled- release carrier intended to resolve metastatic breast cancer bone lesions, inhibit pain while regenerating bone, with the potential to increase survival rates.

ZetaMet’s (Zeta-BC-003) small molecule mechanism of action (MOA) via a novel molecular pathway initiates a circuit which results in tumor cell death.

The US Food & Drug Administration (FDA) has recognized Zetagen’s discoveries with multiple Breakthrough Designations including ZetaMet™ (Zeta-BC-003).

Zetagen with FDA approval via the Expanded Access (Compassionate Use) program has treated several patients with ZetaMet™ (Zeta-BC-003) with results published in multiple peer-reviewed journals.

Peer-reviewed 2-year follow up clinical data published in 2023 on ZetaMet™ (Zeta-BC-003) demonstrated resolution of 7 lytic lesions (radiated and non-radiated), reduction in pain, significant attrition of opioid pain medication (4-fold), prevention of vertebral fracture, and increased survival rate in a patient living with Stage 4 breast cancer.i To view this publication via open access, go to: https://www.tandfonline.com/doi/full/10.2217/pmt-2023-0069
