Experimental Drug Development Centre's EBC-129 Approved for Fast Track by FDA as Innovative Cancer Treatment

EBC-129 Gains FDA Fast Track Status

The Experimental Drug Development Centre (EDDC) in Singapore has achieved a significant milestone by having its antibody-drug conjugate (ADC), EBC-129, granted Fast Track Designation by the U.S. Food and Drug Administration (FDA) for the treatment of pancreatic ductal adenocarcinoma (PDAC). This designation highlights EBC-129’s potential to meet critical unmet medical needs in a disease that has long been difficult to treat due to its aggressive nature.

EBC-129 is particularly noteworthy as it is the first ADC developed in Singapore to enter clinical trials. Targeting a unique tumour-specific N-glycosylated epitope on CEACAM5 and CEACAM6, it aims to offer new hope to patients suffering from this form of pancreatic cancer. The ADC has demonstrated promising initial results in Phase 1 trials, addressing a significant gap in treatment options for patients facing solid tumours with high unmet need.

Professor Damian O'Connell, CEO of EDDC, emphasized the importance of this designation, stating, “The FDA's Fast Track Designation for EBC-129 underscores the promise of this novel ADC in addressing the critical need for expanded treatment options for PDAC patients and represents an important step in our efforts to accelerate its development.” This commitment to advancing EBC-129 echoes the urgency of finding more effective therapies for a condition characterized by late diagnosis and poor prognosis.

The Fast Track Designation facilitates frequent communication with the FDA to streamline EBC-129's clinical development timeline. It also sets the stage for potential eligibility for Priority Review and Accelerated Approval. Furthermore, it allows for rolling reviews of any subsequent Biologic License Application (BLA) that may arise from EBC-129’s ongoing development.

Clinical Trial Highlights

Currently in the midst of Phase 1 trials, EBC-129 has shown clinical activity in various solid tumours beyond PDAC, indicating its broad applicability. The ongoing study is evaluating its safety and effectiveness both as a standalone treatment and in combination with pembrolizumab, an established PD-1 inhibitor. Notably, the PDAC cohort of the trial is fully enrolled, while recruitment continues for other groups focusing on gastroesophageal adenocarcinoma (GEA) and other cancers that exhibit the specific biomarker.

Upcoming results from this Phase 1 study will be shared at the 2025 Annual Meeting of the American Society of Clinical Oncology (ASCO) scheduled for June 2, 2025, in Chicago. The session will highlight key findings related to the clinical activity of EBC-129 and its potential to redefine treatment paradigms for patients with pancreatic ductal adenocarcinoma.

About EBC-129 and its Mechanism

The innovative aspect of EBC-129 lies in its ability to target a conserved tumor-specific N256-glycosylation site on CEACAM5 and CEACAM6, which are crucial in cancer development, migration, and metastasis. Clinical investigations using validated immunohistochemistry (IHC) assays have detected this marker across multiple cancers, including gastric, oesophageal, and colorectal tumors. Moreover, the delivery mechanism uses monomethyl auristatin E (MMAE), a cytotoxic agent that has shown synergy with PD-1 inhibitors, which strengthens the case for its clinical efficacy.

EDDC's initiatives aim not only to advance scientific inquiry but also to transition cutting-edge research into tangible healthcare solutions that empower patients. Their strategic collaborations with industry and academic partners continue to foster advancements in therapeutic and diagnostic innovations within Singapore and beyond.

Conclusion

As EBC-129 heads towards pivotal clinical outcomes, the Fast Track Designation from the FDA marks a compelling chapter in the journey of this ADC. It represents a beacon of hope for pancreatic cancer patients who urgently need effective treatment options. With ongoing research and forthcoming presentations at prominent medical forums, EBC-129 has the potential to redefine oncology treatment landscapes, highlighting the importance of innovation in tackling some of the most pressing health challenges today.
