Experimental lung cancer drug trial halted early
NCT ID NCT06173505
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage trial tested a new immunotherapy drug called vudalimab combined with chemotherapy as a first treatment for advanced non-small cell lung cancer. It compared this combination to the standard treatment of pembrolizumab plus chemotherapy. The study was terminated early after enrolling only 28 people, so it is unclear if vudalimab offers any benefit.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- vudalimab (an experimental immunotherapy drug) combined with chemotherapy (carboplatin and pemetrexed)
- What this could lead to
- If successful, this could point toward a new first-line treatment option for advanced non-small cell lung cancer.
- What could go wrong
- This trial was terminated early with only 28 participants, so results are very limited. It is too early to know if vudalimab is safe or effective compared to existing treatments.

Key Inclusion Criteria: * Histologically confirmed, locally advanced (unresectable) or metastatic nonsquamous NSCLC * Documented absence of tumor activating EGFR mutation, ALK gene and ROS1 rearrangements, and alterations in any actionable driver oncogenes for which there are locally approved targeted first-line therapies * PD-L1 IHC testing documenting TPS \< 49% * No prior systemic treatment for advanced/metastatic NSCLC. * Measurable disease by RECIST 1.1 * ECOG performance status score of 0 or 1 * Life expectancy ≥ 3 months * Adequate liver, kidney, thyroid and bone marrow function Key Exclusion Criteria: * Have known active central nervous system metastases and/or carcinomatous meningitis. Patients with treated brain metastases may participate, provided they are radiologically stable * Active known or suspected autoimmune disease * Has any condition requiring systemic treatment with corticosteroids, prednisone equivalents, or other immunosuppressive medications within 14 days prior to first dose of study drug * Interstitial lung disease that is symptomatic * Known human immunodeficiency virus (HIV) positive with CD4+ T-cell (CD4+) count \< 350 cells/μL, or an HIV viral load greater than 400 copies/mL, or a history of an acquired immunodeficiency syndrome-defining opportunistic infection within the past 12 months, or not on established antiretroviral therapy (ART) for at least 4 weeks prior to initiation of study drug dosing. (HIV positive subjects who do not meet these exclusion criteria are eligible) * Positive test for hepatitis C RNA (a patient who is hepatitis C virus \[HCV\] antibody positive but HCV RNA negative due to documented, curative prior antiviral treatment or natural resolution is eligible) * Positive test for hepatitis B surface antigen or hepatitis B core antibody (hBcAb) (a patient whose hBsAg is negative and hBcAb is positive may be enrolled if a hepatitis B virus (HBV) DNA test is negative and the subject is retested for HbsAg and HBV DNA every 2 months) * History or evidence of any clinically unstable/uncontrolled disorder, condition, or disease (including, but not limited to, cardiopulmonary, renal, metabolic, hematologic, or psychiatric) other than NSCLC, that, in the opinion of the Investigator, would pose a risk to patient safety or interfere with study evaluations, procedures, or completion Other protocol defined inclusion/exclusion criteria apply.
