ER+/HER2− Breast Cancer Disease Understanding and Treatment Algorithm
ER+/HER2− Breast Cancer Overview
Breast Cancer initiates when abnormal cancerous cells in the breast grow and multiply without stopping, creating a tumor. It usually starts in the ducts or lobules of the breast. Cancer cells get many signals that drive their growth. These signals may take the form of hormones.
Hormone receptors are proteins that receive hormone signals and tell the cancer cells to grow. If Breast Cancer cells get signals from the hormone estrogen that could promote tumor growth, it is known as estrogen receptor-positive (ER+) Breast Cancer. If cancerous cells get signals from the hormone progesterone that could promote growth, it is known as progesterone receptor-positive (PR+) Breast Cancer. Breast Cancer that is ER+ or PR+ falls under the category of hormone receptor-positive (HR+) Breast Cancer.
Additionally, there is another category of Breast Cancer, which is known as hormone receptor-negative (HR−). This type of Breast Cancer has cells without hormone receptors. HR- Breast Cancer cells do not depend on estrogen or progesterone to grow.
Addition to this, there is another factor, which is also responsible for Breast Cancer, which is known as human epidermal growth factor receptor 2 (HER2). Human epidermal growth factor receptor-2 is a gene that helps control how cells grow, divide, and repair themselves. These proteins are receptors on breast cells. Human epidermal growth factor receptor-2 positive (HER2+) is Breast Cancer that tests positive for the HER2 protein. HER2+ Breast Cancer tends to grow faster and is more likely to spread and come back compared to human epidermal growth factor receptor-2 negative (HER2−) Breast Cancer. Patients HER2 status is determined by whether Breast Cancer tests are positive or negative for the HER2 protein.
In HER2−negative, cancer cells do not have high amount of a protein called HER2 on their surface. Cancer cells that are HER2 negative may grow more slowly and are less likely to recur (come back) or spread to other parts of the body than cancer cells that have a large amount of HER2 on their surface. Checking for HER2 on some types of cancer cells may help plan treatment.
ER+/HER2− Breast Cancer Diagnosis
The diagnosis of Breast Cancer depends on the presentation of the lesion by mammographic screening, other radiological imaging (such as ultrasound) or by a physical presence. In all cases, it is important to combine the radiologic assessment of the entire affected breast and the contralateral breast with the general health of the woman, examination of the breast and nodal areas, and pathological diagnosis. The treatment of Breast Cancer will depend on combining the results of these investigations.
ER+/HER2− Breast Cancer Treatment
Estrogen receptor (ER) expression is the main indicator of potential responses to hormonal therapy, and most of the human Breast Cancers are hormone-dependent and ER-Positive. A number of classes of anti-estrogenic agents available for patients with early, advanced, or metastatic Breast Cancer, which includes selective estrogen receptor modulators (SERMs), aromatase inhibitors (AIs), and a selective estrogen receptor degrader. However, the clinical development of combinations of antiestrogenic therapy with targeted agents that inhibit the phosphatidylinositol 3 kinase (PI3K)/akt murine thymoma viral oncogene (AKT)/mammalian target of rapamycin inhibitor (mTOR) signaling pathway or the cyclin-dependent kinase 4/6 (CDK4/6) pathway at the G1/S checkpoint of the cell cycle is currently a key focus of clinical research in patients with Hormone-Receptor Positive Breast Cancer who have demonstrated disease recurrence or progression.
The disease epidemiology covered in the report provides historical as well as forecasted epidemiology segmented by total incident population of Breast Cancer, incidence of Breast Cancer cases by menopausal status, stage-specific incidence of Breast Cancer, subtype-specific incidence of Breast Cancer, and treatment eligible pool for localized and metastatic Breast Cancer in the 7MM market covering the United States, EU4 countries (Germany, France, Italy, and Spain), the United Kingdom, and Japan from 2019 to 2032.

This drug is also used as a first-line maintenance treatment of BRCA-mutated advanced ovarian cancer. LYNPARZA is now indicated for the adjuvant treatment of adult patients with deleterious or suspected deleterious gBRCAm HER2− high-risk early Breast Cancer who have been treated with neoadjuvant or adjuvant chemotherapy.
Note: Detailed current therapies assessment will be provided in the full report of ER+/HER2− Breast Cancer
Elacestrant: Radius Pharmaceuticals
Elacestrant is a selective estrogen receptor degrader (SERD), out-licensed to Menarini Group, which is being evaluated for potential use as a once-daily oral treatment for HR+ Breast Cancer. Studies completed to date indicate that the compound has the potential for use as a single agent or in combination with other therapies to treat Breast Cancer. In October 2017, Radius Health announced that the US FDA granted Fast Track Designation to elacestrant for the treatment of women with ER+ and HER2− advanced or metastatic Breast Cancer.
Giredestrant (RG6171, GDC-9545): Roche
Giredestrant is an investigational SERD designed to block ER signalling entirely with robust receptor occupancy. Estrogen encourages HR+ Breast Cancer cells to grow by attaching to the ER. Giredestrant works by blocking this receptor to prevent the action of estrogen and, in the process, causes the receptor to be degraded. This investigational medicine has also shown efficacy regardless of ESR1 mutation status (mutations in the ESR1 gene are important mechanisms of resistance to hormone therapy). In December 2020, giredestrant received the Fast Track Designation from the US FDA for ER+, HER2−, second and third-line metastatic Breast Cancer.
Camizestrant (AZD9833): AstraZeneca
Camizestrant (AZD9833) is an oral SERD that has shown antitumor efficacy in a range of preclinical models of Breast Cancer. This compound was demonstrated to be a highly potent SERD that showed a pharmacological profile comparable to fulvestrant in its ability to degrade ERα in both MCF-7 and CAMA-1 cell lines. Stringent control of lipophilicity ensured that it had favorable physicochemical and preclinical pharmacokinetic properties for oral administration. This is combined with the demonstration of potent in vivo activity in mouse xenograft models. In June 2021, AstraZeneca initiated a Phase III clinical trial, SERENA-6, to evaluate the safety and efficacy of AZD9833 in combination with a CDK4/6 inhibitor (palbociclib or abemaciclib) for the treatment of patients with HR+, HER2− metastatic Breast Cancer with a detectable ESR1 mutation.
LY3484356 (imlunestrant): Eli Lilly
LY3484356 (imlunestrant) is a chemical entity that functions as an oral selective estrogen receptor degrader (SERD). It is being studied to treat the second line ER+, HER2− metastatic Breast Cancer (mBC). The drug is currently in Phase III trial (NCT04975308; EMBER-3). The study’s primary purpose is to measure how well imlunestrant works compared to standard hormone therapy and how well imlunestrant with abemaciclib works compared to imlunestrant in participants with Breast Cancer that is ER+ and HER2−.
Lerociclib (EQ132): EQRx
Lerociclib (EQ132) is a novel, oral, potent, and selective small-molecule cyclin-dependent kinase (CDK) 4/6 inhibitor. In July 2020, EQRx in-licensed the exclusive development and commercialization rights of lerociclib for the US, Europe, Japan, and all other global markets, excluding the Asia-Pacific region (except Japan), from G1 Therapeutics. Genor Biopharma (Genor) holds the development and commercialization rights to lerociclib within the Asia-Pacific region (except Japan).
Note: Detailed emerging therapies assessment will be provided in the final report.
ER+/HER2− Breast Cancer Market Outlook
Breast Cancer is the second most common cancer in women and men worldwide, and among all types of Breast Cancer, estrogen receptor-positive (ER+) Breast Cancer is the most common type of cancer diagnosed in patients with Breast Cancer. ER+ Breast Cancer cells have a receptor that attaches to estrogen, which helps them to grow. According to the statement of the American Cancer Society, about two out of every three cases of Breast Cancer are HR+, and in those cases, most of the cases are ER+.
The stage (extent) of breast cancer is an essential factor in making treatment decisions. Most women with breast cancer in Stages I, II, or III are treated with surgery, often followed by radiation therapy. Most women with breast cancer in Stages I–III will get some drug therapy as part of their treatment. This may include chemotherapy, hormone therapy (tamoxifen, an aromatase inhibitor, or one followed by the other), HER2 targeted drugs, such as trastuzumab (Herceptin) and pertuzumab (Perjeta), and some combination of these. The drugs that might work best depend on the tumor’s hormone receptor status, HER2 status, and other factors.
Among Stage I breast cancers, for women who have an HR+ (ER+ or PR+) breast cancer, most doctors recommend hormone therapy (tamoxifen or an aromatase inhibitor, or one followed by the other) as an adjuvant (additional) treatment, no matter how small the tumor is. Women with tumors larger than 0.5 cm across may be more likely to benefit from it. Hormone therapy is typically given for at least 5 years. If the tumor is larger than 1 cm across, adjuvant chemotherapy is sometimes recommended. A woman’s age at the time of diagnosis may help in deciding if chemotherapy should be offered or not. Some doctors may suggest chemotherapy for smaller tumors as well, especially if they have any unfavourable features (cancer that is growing fast; HR−, HER2+; or having a high score on a gene panel). For HER2+ cancers, 6 months to a year of adjuvant trastuzumab (Herceptin) is usually recommended as well.
Furthermore, systemic therapy is recommended for women with Stage II breast cancer. Some systemic therapies are given before surgery (neoadjuvant therapy), and others are given after surgery (adjuvant therapy). Neoadjuvant treatments are often a good option for women with large tumors because they can shrink the tumor before surgery, possibly enough to make breast-conserving surgery an option. But this does not improve survival more than getting these treatments after surgery. In some cases, systemic therapy may be started before surgery and then continued after surgery.
Most often, Stage III cancers are treated with neoadjuvant chemotherapy (before surgery). For HER2+ tumors, the targeted drug trastuzumab (Herceptin) is given as well, sometimes along with pertuzumab. This may shrink the tumor enough to allow a woman to have breast-conserving surgery (BCS). If the tumor does not shrink enough, a mastectomy is done. Nearby lymph nodes will also need to be checked. A sentinel lymph node biopsy (SLNB) is often not an option for Stage III cancers, so an axillary lymph node dissection (ALND) is usually done.
Currently available drugs include (a) tamoxifen, a prodrug that blocks estrogen uptake by the ER; (b) aromatase inhibitors (letrozole, anastrozole, and exemestane), which suppress the conversion of androgens to estrogens, thus resulting in estrogen depletion; (c) luteinizing hormone-releasing hormone analogs (goserelin and leuprolide), which suppress the production of hormone from the ovary; and (d) fulvestrant (a selective ER degrader), which is suitable for breast cancer patients refractory to previous hormonal therapy. Sequential administration of endocrine treatments is recommended until there is a need for rapid response or evidence of clinical resistance when chemotherapy is indicated.
The ER+/HER2− Breast Cancer pipeline possessed multiple potential drugs in late- and mid-stage developments to be launched shortly. Key players involved in robust research and development include Radius Pharmaceuticals (Elacestrant), AstraZeneca (Camizestrant (AZD9833)), Roche (Giredestrant), Sermonix Pharmaceuticals (Lasofoxifene), AstraZeneca and Daiichi Sankyo (Datopotamab deruxtecan), Eli Lilly (Imlunestrant), Veru (Enobosarm), Roche/Genentech (Inavolisib), Tyme (SM-88), Gilead Sciences (TRODELVY) are some of the major players that are going to alter the market dynamics in the coming years.
