HR Positive/ HER2 Negative Breast Cancer Overview

A breast cancer is classified as HR-positive if its cells have receptors for the hormones estrogen and progesterone, which suggests the cancer cells receive signals from these hormones that promote their growth. Cancer tissue is also tested for HER-2 proteins, or receptors, that help control the growth and repair of breast cells in which HER-2-negative breast cancers, have cells that contain little to no HER-2 protein, so they tend to grow more slowly and have a better outlook than HER-2-positive cancers The breast cancer subtype HR+/HER2- is the most common subtype with an age-adjusted rate of 87.4 new cases per 100,000 women, based on 2015–2019 cases. HER2 or ERBB2 gene is responsible for coding HER2 or ERBB2 proteins which are the receptors on the breast. A HER2-negative diagnosis also means that your cancer won’t benefit from therapies that target the HER2 protein. Roughly half of metastatic breast cancers are both HR-positive and HER2-negative.

HR Positive/ HER2 Negative Breast Cancer Emerging Drugs Profile

• Camizestrant: AstraZeneca

Camizestrant is a potent, next-generation oral SERD and pure ERα antagonist, that has demonstrated anti-cancer activity across a range of preclinical models, including those with ER-activating mutations. The asset has been shown to promising anti-tumour profile when administered alone or in combination with palbociclib and thus, the company is running a Phase III trial for the same.

• Dato-DXd: Daiichi Sankyo, Inc.

Datopotamab deruxtecan (Dato-DXd) is an investigational currently in Phase III for HR-positive, HER2- negative breast cancer. It is a TROP2 directed antibody drug conjugate (ADC) designed using Daiichi Sankyo’s proprietary DXd ADC technology, datopotamab deruxtecan is one of the three lead ADCs in the oncology pipeline of Daiichi Sankyo, and one of the most advanced programs in AstraZeneca’s ADC scientific platform. Datopotamab deruxtecan is comprised of a humanized anti-TROP2 IgG1 monoclonal antibody, developed in collaboration with Sapporo Medical University, attached to a number of topoisomerase I inhibitor payloads, an exatecan derivative, via tetrapeptide-based cleavable linkers.

• CX-2009: CytomX Therapeutics

CX-2009 is a Probody drug conjugate that consists of a humanized anti-CD166 monoclonal antibody conjugated to DM4, a potent microtubule inhibitor known to be active against multiple cancer types. It is currently being tested in Phase II trial in Advanced HR-Positive/HER2-Negative Breast Cancer and of Praluzatamab Ravtansine as Monotherapy and in Combination with Pacmilimab (CX-072) in Advanced Triple-Negative Breast Cancer.

• RGT-419B: Regor Therapeutics

RGT-419B is a new generation of CDK inhibitor with an optimized kinase activity spectrum. The clinical development program of RGT-419B is designed to address the unmet medical needs of patients who are refractory or have relapsed after previous treatment, providing new opportunities to improve survival and quality of life for patients with advanced/metastatic breast cancer. It is currently being tested in Phase I trial in in subjects with Hormone Receptor Positive, Human Epidermal Growth Factor Receptor 2 Negative Advanced/Metastatic Breast Cancer.
