The Therapeutic Significance of HER3 in Non-small Cell Lung Cancer (NSCLC): A Review Study

Review

Author: Ding, Ke ; Zhang, Jinwei ; Trinder, Amelia

HER3 (Human Epidermal Growth Factor Receptor 3) is frequently overexpressed in various cancers, including non-small cell lung cancer (NSCLC), with a prevalence of 83% in primary tumors. Its involvement in tumorigenesis and resistance to targeted therapies makes HER3 a promising target for cancer treatment. Despite being initially considered “undruggable” due to its lack of catalytic activity, significant progress has been made in the development of anti-HER3 therapeutics. Monoclonal antibodies such as lumretuzumab, seribantumab, and patritumab have shown potential in targeting HER3 to overcome resistance to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs). Additionally, antibody-drug conjugates (ADCs) like HER3-DXd (patritumab deruxtecan) are new drug candidates that have demonstrated selective delivery of cytotoxic chemicals to NSCLC cells by exploiting HER3's widespread expression, minimizing cytotoxicity. This review aims to evaluate the efficacy of current HER3 therapeutics in development and their therapeutic potential in NSCLC, incorporating evidence from clinical trials.

ErbB3 Governs Endothelial Dysfunction in Hypoxia-Induced Pulmonary Hypertension

Article

Author: Zhang, Junting ; Chen, Yuan ; Yang, Xusheng ; Li, Yiying ; Deng, Lin ; Chen, Rongchang ; Nie, Xiaowei ; Bian, Jin-Song ; Tan, Jianxin ; Chen, Jingyu

BACKGROUND::

Pulmonary hypertension, characterized by vascular remodeling, currently lacks curative therapeutic options. The dysfunction of pulmonary artery endothelial cells plays a pivotal role in the initiation and progression of pulmonary hypertension (PH). ErbB3 (human epidermal growth factor receptor 3), also recognized as HER3, is a member of the ErbB family of receptor tyrosine kinases.

METHODS::

Microarray, immunofluorescence, and Western blotting analyses were conducted to investigate the pathological role of ErbB3. Blood samples were collected for biomarker examination from healthy donors or patients with hypoxic PH. The pathological functions of ErbB3 were further validated in rodents subjected to chronic hypoxia- and Sugen-induced PH, with or without adeno-associated virus-mediated ErbB3 overexpression, systemic deletion, or endothelial cell–specific ErbB3 knockdown. Primary human pulmonary artery endothelial cells and pulmonary artery smooth muscle cells were used to elucidate the underlying mechanisms.

RESULTS::

ErbB3 exhibited significant upregulation in the serum, lungs, distal pulmonary arteries, and pulmonary artery endothelial cells isolated from patients with PH compared with those from healthy donors. ErbB3 overexpression stimulated hypoxia-induced endothelial cell proliferation, exacerbated pulmonary artery remodeling, elevated systolic pressure in the right ventricle, and promoted right ventricular hypertrophy in murine models of PH. Conversely, systemic deletion or endothelial cell–specific knockout of ErbB3 yielded opposite effects. Coimmunoprecipitation and proteomic analysis identified YB-1 (Y-box binding protein 1) as a downstream target of ErbB3. ErbB3 induced nuclear translocation of YB-1 and subsequently promoted hypoxia-inducible factor 1/2α transcription. A positive loop involving ErbB3-periostin-hypoxia–inducible factor 1/2α was identified to mediate the progressive development of this disease. MM-121, a human anti-ErbB3 monoclonal antibody, exhibited both preventive and therapeutic effects against hypoxia-induced PH.

CONCLUSIONS::

Our study reveals, for the first time, that ErbB3 serves as a novel biomarker and a promising target for the treatment of PH.

(Nasdaq: ELEV), an innovative oncology company focused on the discovery and development of selective cancer therapies to treat patients across a range of solid tumors with significant unmet medical needs, today announced financial results for the quarter and full-year ended December 31, 2024, and highlighted recent business achievements. "We continue to advance our Claudin 18.2 ADC program, EO-3021, for the treatment of advanced gastric/GEJ cancer in the earlier lines settings," said Joseph Ferra, President and Chief Executive Officer of Elevation Oncology. "Based on the competitive anti-tumor activity and differentiated safety profile observed to date, we believe EO-3021 has the potential to benefit a broad patient population. Currently, we are evaluating EO-3021 in combinations with approved therapies in the first- and second-line settings, where we have a first-mover advantage and the opportunity to address significant markets, while also progressing our monotherapy cohort toward an additional data readout in the second quarter of 2025." Mr. Ferra continued, "In the first quarter, we introduced prospective Claudin 18.2 testing to the monotherapy dose expansion cohort of our ongoing Phase 1 trial. This will further enhance our understanding of the patients most likely to benefit from treatment with our ADC and ultimately inform the design of future registrational studies. In addition, we continue to develop our HER3 ADC EO-1022 for the treatment of a wide range of HER3-expressing solid tumors and look forward to sharing preclinical data at the AACR Annual Meeting next month. We believe both EO-3021 and EO-1022 have the potential to elevate cancer care and are eager to share updates on both programs as we move through 2025." Recent Business Achievements Claudin 18.2 ADC EO-3021: In January 2025, Elevation Oncology implemented prospective Claudin 18.2 expression testing as part of the patient screening process in its ongoing Phase 1 clinical trial of monotherapy EO-3021. The dose expansion portion of the trial is now enrolling patients with ≥ 25% of tumor cells at IHC 1+/2+/3+, representing a moderately broader population compared to the exploratory efficacy analysis, which will continue to include patients with ≥ 20% of tumor cells at IHC 2+/3+. In January 2025, Elevation Oncology initiated dosing in the combination cohorts of its Phase 1 clinical trial of EO-3021. The combination cohorts are evaluating EO-3021 in combination with dostarlimab, a PD-1 inhibitor, in the first-line setting and with ramucirumab, a VEGFR2 inhibitor, in the second-line setting for the treatment of advanced gastric/GEJ cancer. In December 2024, Elevation Oncology presented preclinical proof-of-concept data supporting the combination potential of EO-3021 with VEGFR2 or PD-1 inhibitors at the ESMO Immuno-Oncology Annual Congress 2024 (ESMO-IO). The in vivo data showed: Treatment with EO-3021 and DC101, a surrogate of VEGFR2 inhibitor ramucirumab, exhibited statistically superior tumor growth inhibition (TGI) compared to treatment with either EO-3021 or DC101 alone (TGI: 88.2% for EO-3021 in combination with DC101, compared to 20.1% for EO-3021 and 59.2% for DC101 alone). Treatment with EO-3021 and a PD-1 inhibitor exhibited statistically superior TGI compared to treatment with either EO-3021 or a PD-1 inhibitor alone (TGI: 79.9% for EO-3021 in combination with a PD-1 inhibitor, compared to 33.8% for EO-3021 and 25.0% for a PD-1 inhibitor alone). 92% (11/12) of mice treated with the combination of EO-3021 and a PD-1 inhibitor achieved a complete response (CR), compared to 50% (6/12) mice treated with EO-3021 monotherapy and 17% (2/12) mice treated with a PD-1 inhibitor alone. HER3 ADC EO-1022: In December 2024, Elevation Oncology nominated EO-1022 as its HER3 ADC development candidate for the treatment of HER3-expressing solid tumors including breast cancer and non-small cell lung cancer. EO-1022 is designed to be a differentiated HER3 ADC, leveraging seribantumab's desirable internalization properties, the latest site-specific ADC technology and the MMAE payload. Expected Upcoming Milestones EO-3021: Report additional safety and efficacy data from the ongoing Phase 1 clinical trial of monotherapy EO-3021, including from the dose escalation and expansion cohorts, in the second quarter of 2025. Report initial data from the combination cohorts of the Phase 1 clinical trial of EO-3021 in the fourth quarter of 2025 or the first quarter of 2026. EO-1022: Present preclinical data for EO-1022 at AACR Annual Meeting in the second quarter of 2025. File an IND application for EO-1022 in 2026. Fourth Quarter and Full Year 2024 Financial Results As of December 31, 2024, Elevation Oncology had cash, cash equivalents and marketable securities totaling $93.2 million, compared to $83.1 million as of December 31, 2023. The increase in cash reflects net proceeds of $44.2 million, which Elevation Oncology raised through its at-the-market (ATM) facility in the first half of 2024, partially offset by cash used to fund operating activities. Research and development (R&D) expenses for the fourth quarter of 2024 were $6.6 million, compared to $4.7 million for the fourth quarter of 2023. The increase in R&D expenses in the fourth quarter of 2024 was primarily due to increased clinical trial expenses for the lead program EO-3021. For the year ended December 31, 2024, R&D expenses were $28.6 million, compared to $25.4 million for the year ended December 31, 2023. The increase was primarily driven by continuous investment in the lead and pipeline programs. General and administrative (G&A) expenses for the fourth quarter of 2024 were $4.0 million, compared to $3.3 million for the fourth quarter of 2023. The increase in G&A expenses in the fourth quarter of 2024 was primarily due to increased personnel costs, including stock compensation expenses. For the year ended December 31, 2024, G&A expenses were $16.1 million, compared to $14.9 million for the year ended December 31, 2023. The increase was primarily due to increased professional fees and personnel expenses, partially offset by a decrease in premiums paid on directors' and officers' insurance. Net loss for the fourth quarter of 2024 was $10.4 million, compared to $7.9 million for the fourth quarter of 2023. Financial Outlook Elevation Oncology expects that its cash, cash equivalents and marketable securities as of December 31, 2024, will be sufficient to fund its current operations into 2026.
