Breakthrough Clinical Results
Boehringer Ingelheim announced the approval of HERNEXEOS® (zongertinib) by China's NMPA for treating adult patients with unresectable, locally advanced, or metastatic non-small cell lung cancer (NSCLC) with activating HER2 mutations and prior systemic therapy. The approval is based on data from the Phase Ib Beamion-LUNG 1 trial, showing a 71% objective response rate. Zongertinib is an oral, irreversible tyrosine kinase inhibitor that selectively targets HER2. The drug also received Breakthrough Therapy Designation for first-line treatment of HER2-mutant NSCLC in China.

Drug used in other indications
Zongertinib Clinical Trials Beyond NSCLC
Based on a thorough examination of available information, there is insufficient data to determine which indications Zongertinib (JAB-21822) is being trialed for beyond Non-small cell lung cancer (NSCLC).
The current clinical development program for Zongertinib appears to be focused primarily on NSCLC, but comprehensive details about trials for other indications are not available in the current literature. Without access to complete clinical trial registries or recent pharmaceutical development updates, it is not possible to identify:
- Additional oncological indications that might be under investigation
- Potential non-oncological applications of the drug
- The specific intervention models being employed in these trials
- Study designs for trials beyond the NSCLC indication
- Dosing regimens being tested for alternative indications
As Zongertinib is a relatively novel therapeutic agent, its full clinical development pipeline may still be evolving. Pharmaceutical companies often expand their clinical trial programs to additional indications after establishing initial safety and efficacy data in a primary indication.
For the most current and accurate information about Zongertinib's clinical development beyond NSCLC, consulting official clinical trial registries such as ClinicalTrials.gov, reviewing recent scientific publications, or examining investor information from the developing pharmaceutical company would be recommended.
The absence of detailed information about additional indications suggests that either these trials are in early planning stages, have not yet been publicly registered, or that the current development focus remains primarily on establishing Zongertinib's efficacy in NSCLC before expanding to other therapeutic areas.
Incidence and Prevalence
Global Estimates of Non-small Cell Lung Cancer (NSCLC)
Non-small cell lung cancer (NSCLC) accounts for over 85% of all lung cancers, according to multiple sources from 2022-2024. This makes it the predominant form of lung cancer diagnosed worldwide.
Lung cancer as a whole kills 1.8 million people each year and represents the main cause of cancer mortality worldwide based on 2022 statistics. It is consistently described as "one of the world's most common and deadly cancers" and "a leading cause of cancer-related death worldwide" in recent publications.
Specifically, Non-Small Cell Lung Cancer (NSCLC) is noted as "the leading cause of cancer-related death in the United States" in a 2023 publication and is characterized as "one of the most deadly human cancers" in literature from 2019. A 2024 publication reinforces that lung cancer is "the highest contributor to cancer-associated mortality worldwide."
While the overall lung cancer incidence has steadily declined over the last decade, important disparities in incidence and mortality rates persist among African American (AA), Caucasian American (CA), and Hispanic American (HA) populations, as noted in a 2025 publication.
The global burden of NSCLC is significant, though the available data does not provide exact current global incidence and prevalence figures beyond stating that NSCLC represents more than 85% of all lung cancer cases.
Limited geographical distribution data indicates that historically, lung cancer showed significantly decreased mortality in East African immigrants to England and Wales during 1970-85, with overall cancer mortality being low for lung cancer in both sexes among this population.
In the broader cancer landscape, lung cancer is identified as "the first" most general cancer, with breast cancer being the second most common, according to a 2021 publication.
The high mortality rate associated with NSCLC underscores its significance as a global health challenge, requiring continued research into genetic factors, biomarkers, and treatment approaches to improve outcomes for patients worldwide.
Key Unmet Needs in Non-small Cell Lung Cancer (NSCLC)
Molecular Understanding and Targeted Therapies
Recent research highlights significant gaps in our molecular understanding of NSCLC. The role of circDLG1 in regulating the miR-144/AKT/mTOR signaling axis offers potential diagnostic and therapeutic targets. Despite FDA approval of ALK inhibitors, cancer cell resistance remains inevitable, necessitating alternative approaches like monoclonal antibody screening or combination therapies. For EGFR-mutated NSCLC, while combinations like bevacizumab and erlotinib improved progression-free survival, they failed to improve overall survival and increased adverse events. EGFR-TKIs face challenges with acquired drug resistance leading to tumor progression. For ROS1-rearranged patients, particularly those with brain metastases, decreased clinical response to crizotinib was observed. HER2-mutant and KRAS-mutated patients represent populations requiring specialized approaches.
Metastasis and Progression
Brain metastasis in lung adenocarcinoma represents a critical unmet need, with RAC1 identified as a potential biomarker associated with worse prognosis. CTNNAL1 regulates cancer stem cells which resist chemotherapeutic drugs and irradiation, presenting obstacles to effective treatment.
Immunotherapy Challenges
Despite the efficacy of immune checkpoint inhibitors, only a subset of patients respond, and many eventually progress. This necessitates novel combination therapies targeting the tumor microenvironment. Humanized mouse models are being used to investigate novel immunotherapeutics and predict immune-related adverse events. For patients previously treated with immunotherapy, the combination of anlotinib plus docetaxel has shown preliminary efficacy.
Prognostic Markers and Risk Models
Apoptosis dysregulation is associated with tumor occurrence and drug resistance. Research has identified four significantly prognostic ARGs and constructed a stable prognostic risk model for lung squamous cell carcinoma. Single-cell RNA sequencing provides new insights into cellular-level tumor development.
Specific Patient Populations
Patients with oncogenic driver mutations require personalized treatment strategies. Those with PD-L1 expression of 50% or greater experience greater benefit from immuno-chemotherapy. MET exon 14 skipping NSCLC (3-4% of cases) faces challenges including limited broad biomarker testing and lack of historical real-world data. Patients in areas with primary care shortages or nonmetropolitan areas face treatment disparities, with higher risks of receiving radiation versus surgery. Patients with spinal metastases from NSCLC have fewer days at home after treatment, representing a gap in supportive care.
Drug Resistance and Novel Approaches
P-glycoprotein-mediated drug resistance remains a major challenge in NSCLC treatment. Silibinin has been identified as promising for suppressing EGFR signaling but faces bioavailability challenges. For RAS-mutant NSCLC, MEK inhibitors lack monotherapy efficacy, indicating a need for combination approaches. A subset of NSCLCs harbor impaired DNA double strand break repair, suggesting potential for PARP inhibition therapy.
