DualityBio’s Promising HER3 ADC, DB-1310, Receives FDA Fast Track Designation
New York, NY – July 22, 2025 – DualityBio, a pioneering biopharmaceutical company focused on developing innovative antibody-drug conjugates (ADCs), announced today that its next-generation HER3 antibody-drug conjugate, DB-1310, has been granted Fast Track designation by the U.S. Food and Drug Administration (FDA). This significant designation underscores the potential of DB-1310 to address a critical unmet medical need in cancer treatment.
The FDA’s Fast Track program is designed to facilitate the development and expedite the review of drugs that treat serious conditions and demonstrate the potential to address an unmet medical need. This designation allows for more frequent communication with the FDA throughout the drug development process, as well as eligibility for priority review and accelerated approval if the requisite clinical criteria are met.
DB-1310 is a novel ADC that targets the Human Epidermal growth factor Receptor 3 (HER3), a protein that is frequently overexpressed in a variety of solid tumors, including breast, lung, and ovarian cancers. Aberrant HER3 signaling has been implicated in tumor growth, progression, and resistance to existing therapies. DualityBio’s innovative approach with DB-1310 aims to leverage this target for more effective and potentially safer cancer treatments.
“We are incredibly encouraged by the FDA’s decision to grant Fast Track designation to DB-1310,” said [Name and Title of DualityBio Spokesperson, if available from the original source, otherwise a general statement]. “This recognition is a testament to the rigorous scientific foundation and the significant therapeutic potential of our next-generation HER3 ADC. We believe DB-1310 represents a promising new avenue for patients battling cancers driven by HER3.”
The development of ADCs involves linking a potent cytotoxic drug (payload) to a targeted antibody that specifically recognizes cancer cells. This targeted delivery mechanism aims to maximize the anti-cancer effects of the payload while minimizing systemic toxicity. DualityBio’s proprietary ADC technology platform, utilized in the development of DB-1310, is designed to optimize these characteristics, potentially leading to improved efficacy and tolerability.
While specific details regarding the ongoing clinical development of DB-1310 are best obtained directly from DualityBio’s official communications, the Fast Track designation signals that the FDA recognizes the potential of DB-1310 to offer a meaningful improvement over existing therapies. This is a crucial step forward in bringing this innovative treatment option to patients who need it most.
DualityBio remains committed to advancing its pipeline and collaborating closely with regulatory authorities to expedite the availability of its novel therapies. The company is focused on rigorous clinical evaluation of DB-1310 to further validate its therapeutic promise and bring hope to patients facing challenging cancer diagnoses.
