New hope for lung cancer: drug cocktail trial launches
NCT ID NCT06731907
First seen Jun 26, 2026 · Last updated Aug 19, 2026 · Updated 3 times
Summary
This phase 2 trial is testing whether adding a targeted drug called HER3-DXd to standard immunotherapy (pembrolizumab) and chemotherapy can help people with advanced non-small cell lung cancer that hasn't been treated yet. About 90 participants will receive different combinations to see which works best and is safest. The goal is to improve tumor shrinkage and control the disease longer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- pembrolizumab (Keytruda) plus chemotherapy and/or HER3-DXd (patritumab deruxtecan)
- What this could lead to
- If successful, this could lead to a more effective first-line treatment for advanced non-small cell lung cancer, potentially improving response rates and survival.
- What could go wrong
- This is an early phase 2 study with only 90 participants, so results may not apply to all patients. Adding new drugs also raises the risk of side effects.

Inclusion Criteria: The main inclusion criteria include but are not limited to the following: * Histologically or cytologically confirmed diagnosis of Stage IV squamous or non-squamous non-small cell lung cancer (NSCLC) per American Joint Committee on Cancer (AJCC) Staging Manual Version 8. * Has an Eastern Cooperative Oncology Group (ECOG) performance status of either 0 or 1 as assessed within 7 days before randomization. * Has archival tumor tissue sample or newly obtained core, incisional, or excisional biopsy of a tumor lesion not previously irradiated has been provided. * Human immunodeficiency virus (HIV)-infected participants must have well controlled HIV on ART. * Participants who are hepatitis B surface antigen (HBsAg) positive are eligible if they have received hepatitis B virus (HBV) antiviral therapy for at least 4 weeks and have undetectable HBV viral load prior to treatment randomization. Exclusion Criteria: The main exclusion criteria include but are not limited to the following: * Has a diagnosis of small cell lung cancer or, for mixed tumors, presence of small cell elements. * Participants with squamous histology are excluded if there is a known tumor-activating epidermal growth factor receptor (EGFR) mutation or anaplastic lymphoma kinase (ALK) or c ros oncogene 1 (ROS1) gene rearrangement. * Is HIV-infected with a history of Kaposi's sarcoma and/or Multicentric Castleman's Disease * Clinically severe pulmonary compromise resulting from intercurrent pulmonary illnesses including, but not limited to, any underlying pulmonary disorder, or any autoimmune, connective tissue, or inflammatory disorders with pulmonary involvement. * Has evidence of any leptomeningeal disease. * Has known history of, or active, neurologic paraneoplastic syndrome. * Has clinically significant corneal disease. * Has myocardial infarction within 6 months. * Has New York Heart Association (NYHA) Classes 3 or 4 congestive heart failure. * Has uncontrolled angina pectoris within 6 months. * Has cardiac arrhythmia requiring ongoing antiarrhythmic treatment. * Has history of clinically relevant ventricular arrhythmias, such as ventricular tachycardia, ventricular fibrillation, or Torsade de Pointes. * Has bradycardia of less than 50 beats per minute (bpm) unless the participant has a pacemaker. * Has history of second- or third-degree heart block.
