• Emerging HER2 Negative Breast Cancer therapies in the different phases of clinical trials are- ER-PROTAC, RLY-2608, PRT2527, EP0062, BPI-1178, CX-2009, Z-endoxifen, AZD9833, GDC-9545, Gedatolisib, BGB-290, OP-1250, AZD9833, ADG106, Dato-DXd, HRS8807, Ipatasertib, and others are expected to have a significant impact on the HER2 Negative Breast Cancer market in the coming years.

• In January 2025, Genentech Therapeutics’ Phase III trial evaluating Itovebi (inavolisib) in patients with specific forms of metastatic breast cancer has achieved the key oncology benchmark of improved overall survival (OS), while also significantly delaying disease progression. The randomized, double-blind study (NCT04191499) further demonstrated that the combination of Itovebi with Ibrance (palbociclib) and Faslodex (fulvestrant) met a secondary endpoint by delivering a statistically significant and clinically meaningful OS benefit in patients with PIK3CA-mutated, hormone receptor-positive (HR+), and HER2-negative breast cancer.

• In February 2025, Washington University School of Medicine is conducting a Phase Ib/II clinical trial to assess the safety and effectiveness of zunsemetinib (ATI-450) in combination with capecitabine for patients diagnosed with hormone receptor-positive, HER2-negative (HR+/HER2-) metastatic breast cancer (MBC).

• In February 2025, Stemline Therapeutics Inc. is conducting a study to assess the efficacy and safety of elacestrant over a 6-month period in patients with estrogen receptor-positive (ER+)/human epidermal growth factor receptor 2-negative (HER2-) advanced or metastatic breast cancer who have not previously been treated with CDK4/6 inhibitors in the metastatic setting.

• In February 2025, Merck Sharp & Dohme LLC is conducting a study to evaluate the safety and effectiveness of belzutifan (MK-6482) in combination with fulvestrant, compared to everolimus paired with an endocrine therapy (either fulvestrant or exemestane, as selected by the investigator), in adult patients with estrogen receptor-positive, HER2-negative (ER+/HER2-) unresectable metastatic breast cancer. This trial is exploratory and does not involve formal hypothesis testing.

• In February 2025, Puma Biotechnology Inc. is conducting PUMA-ALI-1201, a randomized, multicenter Phase 2 trial aimed at optimizing the dose of alisertib in combination with endocrine therapy for patients with confirmed HR-positive/HER2-negative metastatic breast cancer (MBC). Participants must have experienced disease progression after at least two prior lines of endocrine therapy in the recurrent or metastatic setting. The study will determine the most effective alisertib dose in combination with a selected endocrine therapy and will also assess the combination’s efficacy, safety, and pharmacokinetics. Additionally, the trial seeks to identify biomarker-defined subgroups that may derive the greatest benefit from this therapeutic approach.

• In February 2025, GE Healthcare is conducting a multicenter study across France to assess how ESTROTEP PET/CT imaging influences treatment decisions in patients with metastatic breast cancer (MBC). Each participant will undergo a screening process to ensure they fulfill all inclusion requirements and do not meet any exclusion conditions.

• In December 2024, Olema Pharmaceuticals shared clinical data from its ongoing Phase Ib/II trial evaluating palazestrant in combination with ribociclib for patients with ER-positive/HER2-negative advanced or metastatic breast cancer at SABCS 2024.

HER2 Negative Breast Cancer Overview

HER2-negative breast cancer is a type of breast cancer that tests negative for the human epidermal growth factor receptor 2 (HER2) protein. HER2 is a protein that promotes the growth of cancer cells, and when breast cancer is HER2-negative, it means the cancer cells do not overexpress this protein. This subtype includes hormone receptor-positive and triple-negative breast cancers. Treatment for HER2-negative breast cancer typically excludes HER2-targeted therapies and may involve hormone therapy, chemotherapy, or immunotherapy depending on the specific subtype and stage of the disease.
