HighField Biopharmaceuticals ASCO 2024 Poster Presentation Shows HFK1, a Unique Immunoliposome May Improve Clinical Outcomes over Antibody Drug Conjugates

HFK1 is the company’s groundbreaking drug encapsulated immunoliposome for solid tumors with HER2 low expression

HighField Biopharmaceuticals, a clinical stage company using lipid-based therapeutics to treat cancer, diabetes and other diseases, will present positive clinical and preclinical data of HFK1, a drug encapsulated immunoliposome for treatment of solid tumors, at the American Society of Clinical Oncology annual meeting May 31 – June 4, in Chicago, IL.

The poster presentation describes preliminary findings from the company’s Phase 1a study of HFK1 for HER2 low expression cancers. The first patient dosed suffers from lung metastasis of a rare HER2 low cancer. The patient has been treated with HFK1 for more than five months with no dose-limiting toxicity and stable disease.

The clinical and preclinical data, which will be presented by HighField CEO and Scientific Founder Yuhong Xu, Ph.D., also includes study results comparing HFK1 to other antibody drug conjugates (ADCs) and PEGylated liposomal doxorubicin (PLD). The findings demonstrate HFK1 improves significantly on the safety and efficacy of ADCs and PLD. In particular, HFK1 exceeded ADCs in expanding the drug therapeutic window and reducing tumor growth.

“We look forward to sharing the encouraging data of our HFK1 studies at ASCO,” said Dr. Xu. “They confirm our confidence that our unique drug encapsulated immunoliposomes will offer a new alternative for targeting HER2 low cancers with lower off-target toxicities and wider therapeutic windows.”

The poster, titled “The design, preclinical study and Phase 1 dose escalation of a HER2 targeted immunoliposome (HF-K1) for HER2 low solid tumor treatment,” will be presented Saturday, June 1, 2024 (9am -12pm CDT).

HighField’s Phase 1 open-label clinical trial is enrolling patients who have advanced refractory solid tumors with HER2 low expression. The Phase 1a dose escalation portion will be followed by a Phase 1b dose expansion phase. Both the Phase 1a and 1b studies will assess the safety and preliminary efficacy of HFK1.

HighField’s immunoliposomes represent a new generation of targeted chemotherapy drugs following the success of antibody drug conjugates (ADCs). Due to their unique features, HighField’s immunoliposomes may offer better safety with greater efficacy in treatment of a broad range of solid tumor types.
