Key Takeaways from the HER2-Negative Breast Cancer Pipeline Report
- On December 09, 2025- Washington University School of Medicine conducted a phase II study to investigate the potential utility of PD 0332991 in the treatment of early stage ER+ Human epidermal growth factor receptor 2 (HER2)- breast cancer, to investigate whether the combination of PD 0332991 and anastrozole is able to: 1) improve the pathologic complete response rate when compared to the historical control of single agent aromatase inhibitors, 2) result in fewer patients with on therapy Ki67>10% compared to historical control.
- On December 04, 2025- MedSIR announced a phase II clinical trial that is designed to improve the tolerance of sacituzumab govitecan in patients with unresectable locally advanced or metastatic triple negative breast cancer (TNBC) or Luminal breast cancer, refractory to at least one, and no more than two, prior standard of care chemotherapy regimens in this setting that is not amenable to resection with curative intent.
- On December 04, 2025- Merck Sharp & Dohme LLC initiated a phase 3, Randomized, Open-label Study to Evaluate the Efficacy and Safety of Sac-TMT (Sacituzumab Tirumotecan, MK-2870) Followed by Carboplatin/Paclitaxel vs Chemotherapy, Both in Combination With Pembrolizumab as Neoadjuvant Therapy for High-Risk, Early-Stage, Triple-Negative Breast Cancer or Hormone Receptor-low Positive/Human Epidermal Growth Factor Receptor-2 Negative Breast Cancer.

The HER2-Negative Breast Cancer Pipeline Report provides a disease overview, pipeline scenario, and therapeutic assessment of the key pipeline therapies in this domain. The HER2-Negative Breast Cancer Pipeline Report also highlights the unmet needs with respect to the HER2-Negative Breast Cancer.
HER2-Negative Breast Cancer Overview
Breast Cancer is the world’s most common disease in women, and is also a major factor that leads to death. It is reported that 5% of patients with breast cancer have distant metastasis at a diagnosis, and 30% of patients with early cancer subsequently experience the distant metastasis. Metastatic breast cancer cannot be completely cured; however, significant improvement in the survival period was observed consistent with the emergence of novel therapy. The purpose of the treatment for metastatic breast cancer is to prolong the survival period and improve the cancer patients’ quality of life (QOL) by managing cancer-related symptoms. To that end, not the same strategy for all patients but individual approach for each patient should be used. When a breast cancer is HER2-negative, it means that the cancerous cells do not contain high levels of the protein HER2.
HER2-Negative Breast Cancer Emerging Drugs Profile
- Giredestrant : Genentech
Giredestrant is a novel investigative small molecule that works as selective estrogen receptor degrader (SERD) by targeting the estrogen receptor (ER). The drug candidate is a new molecular entity (NME) which is administered through oral route. Preclinical studies suggest that Giredestrant is orally bioavailable and competitively inhibits the binding of estrogen to the ER. In preclinical models, Giredestrant has been shown to restrain the normally dynamic behavior of both wild-type and mutant ER, immobilizing the ER and attenuating the expression of its target genes. Currently, the drug is in Phase III stage of its development for the treatment of HER2 negative breast cancer.
- Inavolisib : Genentech
Inavolisib is an investigational small molecule designed to selectively inhibit mutant PI3Kα. In preclinical models, the molecule showed potent selective inhibition of PI3Kα and has increased potency to mutant PI3K cells over wild type. It is less sensitive for the other three PI3K isoforms. Inavolisib binds to the ATP-binding site of PI3Kα, thereby blocking phosphorylation of PIP2 to PIP3 and preventing downstream signaling as shown in preclinical models. Moreover, inavolisib specifically degrades the mutant form of PI3Kα, resulting in reduction of pathway activity. Currently the drug is in Phase III stage of its development for the treatment of HER2 negative breast cancer.
- CX-2009 : CytomX Therapeutics
CX-2009 (Praluzatamab ravtansine) is a conditionally activated antibody-drug conjugate (ADC) comprised of a CD166-directed humanized monoclonal antibody conjugated to the maytansinoid DM4, a tubulin inhibitor. Praluzatamab ravtansine utilizes CytomX Probody® platform technology, which incorporates a masking peptide to cover and block the cellular binding region of the antibody. Tethered to the antibody via a protease-cleavable linker, currently, the drug is in Phase II stage of its development for the treatment of HER2 negative breast cancer.
- H3B 6545 : H3 Biomedicine
H3B-6545 is an oral, selective estrogen receptor covalent antagonist (SERCA) for the research of metastatic ER-positive, HER2-negative breast cancer. H3B- 6545, a first-in-class small molecule selective estrogen receptor covalent antagonist (SERCA) demonstrates activity in tumor models that harbor wild-type or mutant ERα.4 H3B-6545 activity against ERα mutants resistant to standard therapy provides an opportunity to target a currently unmet medical need both as a single agent and in combination with other breast cancer therapies. Currently, the drug is in Phase II stage of its development for the treatment of HER2 negative breast cancer.
- RGT-419B : Regor Therapeutics
RGT-419B is a new generation of CDK inhibitor with an optimized kinase activity spectrum. Results from non-clinical studies showed that RGT-419B demonstrated full suppression of ER+ breast cancer cell proliferation with acquired resistance to CDK4/6 inhibitors. Additionally, RGT-419B’s tumor cell suppression was further augmented when combined with a selective estrogen receptor down-regulator or a PI3K signaling pathway inhibitor. Currently, the drug is in Phase I stage of its development for the treatment of HER2 negative breast cancer.
