Key Takeaways from the ER+/HER2-ve Breast Cancer Pipeline Report
• DelveInsight's ER+/HER2-ve breast cancer pipeline analysis depicts a robust space with 20+ active players working to develop 25+ pipeline drugs for ER+/HER2-ve Breast Cancer treatment.
• The leading ER+/HER2-ve breast cancer companies include AstraZeneca, Atossa Therapeutics, Inc., Accutar Biotechnology Inc, VelosBio Inc, Merus N.V., Pfizer, Olema Pharmaceuticals, Inc., Eli Lilly and Company, Novartis Pharmaceuticals, Hoffmann-La Roche, Ellipses Pharma, BeiGene, and others are evaluating their lead assets to improve the ER+/HER2-ve Breast Cancer treatment landscape.
• Key ER+/HER2-ve breast cancer pipeline therapies in various stages of development include Camizestrant, (Z)-endoxifen, AC699, Zilovertamab vedotin, Zenocutuzumab, PD0332991, Palazestrant, LY3484356, Letrozole, Ipatasertib, EP0062, BGB-290, and others.
• In February 2025, the FDA granted Lumitron Technologies, Inc. "Breakthrough Device" designation for its HyperVIEWTM X-Ray system, which uses the K-Edge subtraction technique to enable contrast-enhanced imaging for breast cancer diagnosis. This technology utilizes Lumitron's proprietary distributed charge laser-Compton technology, offering 100 times higher resolution and significantly safer imaging compared to standard X-rays.
• In January 2025, the FDA approved AstraZeneca (AZN.L) and Daiichi Sankyo's (4568.T) precision drug, Datroway, for treating advanced breast cancer in patients who have received prior treatment.
• In Dec 2024, ScreenPoint Medical showcased new FDA clearance for advanced capabilities of its leading Breast AI, Transpara, at the 110th Annual Radiological Society of North America (RSNA) meeting (December 1-4, 2024, South Hall #5316). Transpara, the most clinically validated Breast AI on the market, assists radiologists in detecting cancers earlier and reducing recall rates.
In October 2024, Genentech announced that the FDA approved ItovebiTM (inavolisib), in combination with palbociclib (Ibrance®) and fulvestrant, for treating adults with endocrine-resistant, PIK3CA-mutated, HR-positive, HER2-negative, locally advanced or metastatic breast cancer, following recurrence after adjuvant endocrine therapy.

ER+/HER2-ve Breast Cancer Overview
ER-positive, HER2-negative breast cancer is a common subtype in which cancer cells have estrogen receptors (ER-positive) but lack excess HER2 protein. It primarily affects postmenopausal women but can also occur in younger women. These tumors grow in response to estrogen, making hormone therapy a key part of treatment.
Symptoms are similar to other breast cancers and include a breast lump, changes in size or shape, skin dimpling, or pain. Early stages may be asymptomatic, highlighting the importance of routine screening.
While the exact cause is unknown, risk factors include prolonged estrogen exposure (early menstruati0n, late menopause, hormone therapy), age, family history, BRCA mutations, alcohol use, and obesity.
Diagnosis involves imaging (mammogram, ultrasound, MRI) followed by a biopsy. Immunohistochemistry (IHC) testing confirms hormone and HER2 receptor status.
Treatment typically includes surgery (lumpectomy or mastectomy), radiation, and systemic therapy. Hormone therapy (e.g., tamoxifen, aromatase inhibitors) is central, often combined with chemotherapy in high-risk cases. Emerging targeted therapies and clinical trials continue to advance treatment options.

ER+/HER2-ve Breast Cancer Treatment Analysis: Drug Profile
Camizestrant: AstraZeneca
Camizestrant is a next-generation oral selective estrogen receptor degrader (SERD) being developed by AstraZeneca for ER-positive, HER2-negative breast cancer. It has shown promising efficacy in improving progression-free survival (PFS) over fulvestrant, the standard SERD therapy for nearly two decades. In the Phase II SERENA-2 trial, camizestrant demonstrated superior PFS at both 75 mg (7.2 months) and 150 mg (9.2 months) doses, compared to 3.7 months for fulvestrant. Additionally, camizestrant significantly reduced ESR1-mutant circulating tumor DNA, suggesting strong activity against endocrine-resistant tumors. The drug has a favorable safety profile, with mostly manageable side effects such as fatigue, anemia, and mild visual disturbances. Currently in Phase III trials (SERENA-4 and SERENA-6), camizestrant is being studied both as monotherapy and in combination with CDK4/6 inhibitors.

(Z)-endoxifen: Atossa Therapeutics, Inc.
(Z)-endoxifen is the most potent active metabolite of tamoxifen, a widely used selective estrogen receptor modulator (SERM). Atossa Therapeutics is developing a proprietary oral formulation of (Z)-endoxifen that bypasses liver metabolism and stomach acidity to maintain therapeutic potency. Unlike tamoxifen, (Z)-endoxifen exerts stronger anti-estrogen effects and also inhibits PKCβ1, an oncogenic protein, at higher concentrations. It offers similar or enhanced bone-protective benefits with reduced risk of endometrial proliferation. Phase I and early Phase II trials have shown the drug to be well tolerated. (Z)-endoxifen is currently in Phase II development for ER-positive, HER2-negative breast cancer.
