Advances in Lung Cancer Treatment Approaches in the US for 2025

Precision Targeted Therapies for NSCLC

Molecular profiling of lung tumors to detect actionable mutations informs many treatment plans in 2025. Targeted therapies act by inhibiting cancer-related genetic abnormalities, aiming to provide therapeutic benefit with differing side effect profiles compared to conventional chemotherapy.

EGFR-Targeted Treatments Including Aumolertinib and Antibody-Drug Conjugates

• Aumolertinib is an EGFR tyrosine kinase inhibitor (TKI) recently introduced in the US, initially approved in other regions like China. It targets NSCLC tumors with common EGFR mutations (exon 19 deletions, L858R).
• Clinical trials report that combining aumolertinib with platinum-pemetrexed chemotherapy extended median progression-free survival compared to monotherapy, with higher but manageable side effects.
• As adjuvant therapy following surgery, aumolertinib has been associated with reductions in recurrence risk in studied populations.
• The antibody-drug conjugate (ADC) SYS6010, targeting EGFR independent of mutation status, has demonstrated objective response rates around 50% in clinical study populations, including patients with resistance or intolerance to existing EGFR inhibitors. These findings are based on trial data and may support further investigation.

Targeting HER2 with New TKIs and ADCs

• HER2 mutations are another target under active clinical evaluation. The FDA-approved ADC trastuzumab deruxtecan (T-DXd) is available but may have notable side effects requiring monitoring.
• Zongertinib, an oral HER2 TKI, has shown response rates in clinical trials, with side effects such as rash or diarrhea reported. Its safety and efficacy profile is still being defined.
• New HER2 ADCs including SHR-A1811 have demonstrated promising response rates in clinical studies involving previously treated patients; additional data will clarify their role.

ROS1 Inhibitors with Potential Brain Metastasis Activity

• ROS1 gene fusions, identified in a subset of NSCLC cases, are targeted by agents like crizotinib, though challenges such as brain metastases and resistance mutations occur.
• Next-generation ROS1 inhibitors such as JYP0322 have been developed to penetrate the blood-brain barrier and address resistance mutations (e.g., G2032R).
• Early clinical trial data show objective response rates and intracranial activity in treated patients; ongoing studies will further quantify benefits and safety.

Expanding KRAS-Targeted Therapy Beyond G12C

• KRAS mutations are common in NSCLC. Until recently, approved inhibitors targeted G12C mutations (sotorasib, adagrasib).
• The investigational drug zoldonrasib targets the KRAS G12D mutation by inhibiting active conformations of KRAS.
• Phase I studies have reported response rates and disease control in NSCLC patients, with safety profiles under evaluation; further research is ongoing.

Role of Immunotherapy in Lung Cancer Treatment

Immune checkpoint inhibitors continue to be significant in managing advanced NSCLC by modulating immune system response to tumors.

• Agents such as pembrolizumab and nivolumab targeting the PD-1/PD-L1 axis are approved for specific indications and have demonstrated benefits in selected patient populations.
• These immunotherapies are sometimes combined with chemotherapy or targeted treatments as part of treatment regimens.
• Research on immune checkpoint inhibitors targeting other pathways (e.g., TIGIT, with agents like tiragolumab) is ongoing, with varying outcomes reported.

Use of Combination Therapy Approaches

Combining systemic therapies is a common strategy aimed at enhancing effectiveness:

• Chemotherapy plus immunotherapy combinations have been studied across disease stages.
• Targeted therapy plus chemotherapy combinations (e.g., aumolertinib with chemotherapy) have shown prolonged progression-free survival in trials.
• Clinical studies continue to investigate double and triple drug combinations involving novel checkpoint inhibitors to improve outcomes.

Continued Importance of Surgery and Radiotherapy

• Surgery remains a primary option for suitable patients with localized, resectable NSCLC.
• Postoperative adjuvant chemotherapy is considered to reduce recurrence risk depending on individual cases.
• Radiation therapy, sometimes combined with chemotherapy, is used when surgery is not feasible or for locally advanced disease.
• Traditional modalities continue to form integral parts of lung cancer management alongside systemic treatments.

Advances in Diagnostic Methods and Personalized Treatment

• Liquid biopsies detecting circulating tumor DNA can provide insights into mutations and treatment response with minimal invasiveness, complementing tissue biopsies.
• Artificial intelligence (AI) applications are being integrated into clinical workflows at major cancer centers to analyze patient data and assist in personalized treatment decisions.
• These technological advancements aim to refine treatment precision and monitoring.

Considerations Regarding Eligibility, Costs, and Clinical Decision Making

• Patient eligibility for targeted therapies depends on molecular profiling results from biopsies.
• Immunotherapy eligibility frequently involves assessing PD-L1 expression or other biomarkers.
• Disease stage, patient health status, and molecular features guide treatment choices including combination regimens.
• Surgical and radiotherapy candidacy depends on tumor characteristics and patient condition.
• Costs vary widely; many targeted agents and immunotherapies are costly but may be supported by insurance coverage in the US. Clinical trials may offer access to emerging therapies.
• Multidisciplinary consultation with oncology specialists is important for individualized treatment planning and navigating coverage options.

Lung cancer treatment in the US in 2025 includes precision medicine approaches focused on targeting key genetic drivers in NSCLC, supported by immunotherapy and combination therapies. Notable options under clinical use or evaluation include:

• EGFR-targeted therapies such as aumolertinib combined with chemotherapy or used as adjuvant treatment.
• HER2-directed oral TKIs like zongertinib alongside antibody-drug conjugates including SHR-A1811.
• ROS1 inhibitors such as JYP0322 addressing central nervous system involvement.
• KRAS-targeting agents like zoldonrasib expanding mutation-specific therapies.
• Established immunotherapies such as pembrolizumab and nivolumab for selected patients.
• Continued use of surgery and chemotherapy in early-stage NSCLC.
• Integration of liquid biopsy and AI-driven personalized medicine to support clinical decisions.

These developments reflect ongoing efforts to tailor treatment to individual patient and tumor characteristics, aiming to enhance clinical outcomes and support quality of life.
