Introduction
In this article, we describe a novel antibody-drug conjugate (ADC; SGN-LIV1A), targeting the zinc transporter LIV-1 (SLC39A6) for the treatment of metastatic breast cancer. LIV-1 was previously known to be expressed by estrogen receptor-positive breast cancers...
Description of Liv-1 Targeting Antibody Drug Conjugate
In this article, a novel antibody-drug conjugate (ADC; SGN-LIV1A) targeting the zinc transporter LIV-1 (SLC39A6) for metastatic breast cancer treatment is discussed. LIV-1, a transmembrane protein expressed in various cancer types, is the focus of this ADC. The investigational ADC, SGN-LIV1A, comprises a humanized IgG1 antibody linked to monomethyl auristatin E (MMAE). This ADC is designed to target LIV-1 on cell surfaces, inducing potent cytotoxic cell killing. The promising potential of SGN-LIV1A as a therapeutic agent for LIV-1-expressing cancers is highlighted…
Background Information
Liv-1, a zinc transporter expressed in various cancers, is targeted by the investigational ADC SGN-LIV1A. This ADC comprises a humanized IgG1 antibody linked to MMAE for potent cell killing.
Liv-1 Protein and Its Role in Breast Cancer
Liv-1, a zinc transporter, is highly prevalent in breast cancer cells. The investigational ADC SGN-LIV1A targets Liv-1 using a humanized IgG1 monoclonal antibody conjugated to monomethyl auristatin E (MMAE). Liv-1 is expressed in various cancer types and plays a critical role in metastatic progression. The expression of Liv-1 is maintained after hormonal therapy, making it a promising target for ADC therapy in breast cancer patients.
Ladiratuzumab Vedotin (LV) as an Investigational ADC
Ladiratuzumab vedotin (LV), also known as SGN-LIV1A, is an investigational antibody-drug conjugate (ADC) developed to target the zinc transporter LIV-1 (SLC39A6) in various cancer types. This novel ADC combines a humanized IgG1 monoclonal antibody with monomethyl auristatin E (MMAE) via a protease-cleavable linker. When LV binds to LIV-1 on cell surfaces, it triggers internalization and the release of MMAE, leading to potent cytotoxic cell killing. LV shows promising potential as a targeted therapy for cancers expressing LIV-1.
Clinical Trials and Development
The Phase I clinical trial of BRY812, a novel antibody-drug conjugate (ADC) that targets LIV-1, has been initiated for advanced malignant tumors. This third-generation ADC shows promise as a targeted therapy for treating various cancer types.
