A Phase 2 study testing Intismeran Autogene, Pembrolizumab and Carboplatin in people with Squamous Non-small Cell Lung Cancer, run by Merck Sharp & Dohme LLC at 55 sites in 11 countries.
Trial summary
Researchers want to know if intismeran autogene (the study treatment) given with pembrolizumab and chemotherapy can treat metastatic treatment-naive squamous non-small cell lung cancer (NSCLC).

About this study
Official title: A Phase 2, Randomized, Double-Blind, Placebo-Controlled Study of V940 in Combination With Pembrolizumab and Chemotherapy as First-Line Treatment for Participants With Metastatic Squamous NSCLC (INTerpath-013)
Researchers want to know if intismeran autogene (the study treatment) given with pembrolizumab and chemotherapy can treat metastatic treatment-naive squamous non-small cell lung cancer (NSCLC). Intismeran autogene is designed to help a person's immune system attack their specific cancer.
The goal of this study is to learn if people who receive intismeran autogene with pembrolizumab and chemotherapy live longer overall and without the cancer growing or spreading compared to people who receive placebo with pembrolizumab and chemotherapy. A placebo looks like the study treatment but has no study treatment in it. Using a placebo helps researchers better understand the effects of the study treatment.
- Conditions
- Squamous Non-small Cell Lung Cancer
- Being tested
- Intismeran Autogene, Pembrolizumab, Carboplatin, Paclitaxel, Nab-paclitaxel

What is being measured
The primary outcome is the main question the study is designed to answer.
Progression Free Survival (PFS)
PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first as assessed by Response Criteria in Solid Tumors Version 1.1 (RECIST 1.1). PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD. PFS as assessed by blinded independent central review (BICR) will be presented.
Measured: Up to ~32 months
Overall Survival (OS)
OS, defined as the time from randomization to death due to any cause. OS will be presented.
Measured: Up to ~42 months
Secondary outcomes (4)
Overall Response Rate (ORR)
ORR is defined as the percentage of participants with Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1. The percentage of participants who experience CR or PR as assessed by BICR will be presented.
Measured: Up to ~26 months
Duration of Response (DOR)
For participants who demonstrate a confirmed Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1, DOR is defined as the time from first documented evidence of CR or PR until progressive disease (PD) or death. Per RECIST 1.1, PD is defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD. DOR as assessed by BICR will be presented.
Measured: Up to ~42 months
Number of Participants who Experience an Adverse Event (AE)
An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment. The number of participants who experience an AE will be presented.
Measured: Up to ~42 months
Number of Participants who Discontinue Study Intervention Due to an AE
An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment. The number of participants who discontinue study intervention due to an AE will be presented.
Measured: Up to ~24 months

Primary outcome
Progression Free Survival (PFS)
Time frame: Up to ~32 months
PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first as assessed by Response Criteria in Solid Tumors Version 1.1 (RECIST 1.1). PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD. PFS as assessed by blinded independent central review (BICR) will be presented.
Overall Survival (OS)
Time frame: Up to ~42 months
OS, defined as the time from randomization to death due to any cause. OS will be presented.
4 secondary outcomes
Overall Response Rate (ORR)
Time frame: Up to ~26 months
Duration of Response (DOR)
Time frame: Up to ~42 months
Number of Participants who Experience an Adverse Event (AE)
Time frame: Up to ~42 months
Number of Participants who Discontinue Study Intervention Due to an AE
Time frame: Up to ~24 months

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Intismeran Autogene, Pembrolizumab and Carboplatin in people with Squamous Non-small Cell Lung Cancer, run by Merck Sharp & Dohme LLC at 55 sites in 11 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 1 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 55 sites in United States, Argentina, Spain, Taiwan, South Korea and 6 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Toll Free Number (1-888-577-8839, Trialsites@msd.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression Free Survival (PFS) (time frame: Up to ~32 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Oct 2026.
