Six dose levels have been selected for evaluation in the Phase I part of the study: 0.3, 0.6, 1.2, 2.4, 3.6, and 4.8 mg/kg of A166

HER2 positive (Immunohistochemistry (IHC) 2+ with fluorescence in situ hybridization (FISH) confirmation and Immunohistochemistry (IHC) 3+) breast cancer. Treatment with A166 at recommended Phase II dose.

HER2 positive (Immunohistochemistry (IHC) 2+ with fluorescence in situ hybridization (FISH) confirmation and Immunohistochemistry (IHC) 3+) gastric cancer. Treatment with A166 at recommended Phase II dose.

HER2 low expressing (Immunohistochemistry (IHC) 1+ and IHC 2+ without fluorescence in situ hybridization (FISH) confirmation) breast cancer. Treatment with A166 at recommended Phase II dose.

All cancers other than breast cancer with low HER2 expression (Immunohistochemistry (IHC) 1+ and IHC 2+ without fluorescence in situ hybridization (FISH) confirmation) and HER2 positive (IHC2+ with FISH confirmation and Immunohistochemistry (IHC) 3+) cancers other than breast and gastric cancer. Treatment with A166 at recommended Phase II dose.

A166 is an Antibody Drug Conjugate (ADC) targeting HER2 expressing cancer cells.

A166

Jordi Rodon Ahnert, MD, PhD

Open-label, Phase I-II, first-in-human (FIH) study for A166 monotherapy in HER2-expressing or amplified patients who progressed on or did not respond to available standard therapies. Patients must have documented HER2 expression or amplification. The patient must have exhausted available standard therapies. Patients will receive study drug as a single IV infusion. Cycles will continue until disease progression or unacceptable toxicity.

This is an open-label, Phase I-II, first-in-human (FIH) study for A166 as monotherapy in HER2-expressing patients who progressed on or did not respond to available standard therapies. Patients enrolled in this Phase III study must have documented HER2 positivity defined as positive on in situ hybridization (ISH) or next-generation sequencing (NGS) or HER2 expression, defined as at least 1+ by validated immunohistochemistry (IHC) test. The patient must be, in the judgment of the investigator, an appropriate candidate for experimental therapy after available standard therapies have ceased to provide clinical benefit for their disease. Patients will receive study drug as a single IV infusion at the prescribed dose level in each treatment cycle. Cycles will continue until disease progression or unacceptable toxicity. The study is divided into 2 parts (Phase I and Phase II).
