About this study

Official title: Phase II Study of CIMAVAX-EGF in Combination With KRAS G12C Inhibitors as Treatment for Advanced Stage KRAS G12C Mutated NSCLC

This phase II trial tests how well giving CIMAvax-EGF with KRAS G12C inhibitor (sotorasib or adagrasib) for the treatment of patients with KRAS G12C mutated non small cell lung cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Vaccines, such as CIMAvax-EGF, made from specific peptides or antigens may help the body build an effective immune response to kill tumor cells. Sotorasib and adagrasibare in a class of medications called kinase inhibitors. They work by blocking the signals that cause tumor cells to multiply. This helps to stop the spread of tumor cells. Giving CIMAvax-EGF with a KRAS G12C inhibitor may be effective for treating advanced, KRAS G12C mutated non small cell lung cancer.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To identify the 12-month progression free survival (PFS) of patients with advanced stage KRAS G12C mutated non small cell lung cancer (NSCLC) treated with Recombinant Human EGF-rP64K/Montanide ISA 51 Vaccine (CIMAvax-EGF) in combination with KRAS G12C inhibitor.

SECONDARY OBJECTIVE:

  1. To assess response rate, 6-month PFS, safety profile and overall survival of patients treated with the combination of CIMAvax-EGF and KRAS G12C inhibitor.

OUTLINE:

LOADING PHASE: Patients receive CIMAvax-EGF intramuscularly (IM) every 2 weeks for 4 doses in the absence of disease progression or unacceptable toxicity.

MAINTENANCE PHASE: Patients receive CIMAvax-EGF IM every 4 weeks for a total of 1 year of treatment, in the absence of disease progression or unacceptable toxicity. Patients who remain on study beyond 12 months and with antibody titer ≥ 1:4000 at the end of the loading phase may receive CIMAvax-EGF IM every 2 months as long as titer levels continue to be maintained > 1:4000. After the first 6 months of alternate dosing, may receive CIMAvax-EGF IM every 3 months in the absence of disease progression or unacceptable toxicity.

Patients also receive sotorasib orally (PO) once daily (QD) or adagrasib PO twice daily (BID) per their physician choice on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Patients undergo magnetic resonance imaging (MRI) at baseline and as clinically indicated and undergo computed tomography (CT) scan and blood sample collection throughout the study.

After completion of study treatment, patients are followed up every 30 days for 120 days then every 3 months thereafter.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Progression free survival (PFS)

    Will be calculated as the binomial proportion of patients who have not experienced a PFS event within 12 months of study enrollment. The 95% confidence intervals for 12-month PFS will be estimated using Jeffreys method.

    Measured: From enrollment to the loading phase and documentation of disease progression or death, at 12 months

  2. Dose limiting toxicity (Safety lead in)

    Measured: Up to 3 years

Secondary outcomes (5)
  1. Objective response rate (ORR)

    Will be based on Response Evaluation Criteria in Solid Tumors. Will be calculated as the number of patients with a confirmed complete or partial response divided by the total number of patients. The 95% confidence intervals for ORR will be estimated using Jeffreys method.

    Measured: Up to 3 years

  2. Progression free survival (PFS)

    Will also be presented using Kaplan-Meier product limit estimators.

    Measured: From enrollment to the loading phase and documentation of disease progression or death, at 6 months

  3. Median PFS

    Will also be presented using Kaplan-Meier product limit estimators.

    Measured: From enrollment to the loading phase and documentation of disease progression or death, up to 3 years

  4. Overall survival

    Will also be presented using Kaplan-Meier product limit estimators.

    Measured: From study enrollment to the Loading Phase and death from any cause, up to 3 years

  5. Incidence of adverse events (AEs)

    The maximum grade for each type of AEs will be recorded for each patient based on National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. The frequency of AEs will be tabulated by maximum grade per event across all dose levels and cycles.

    Measured: Up to 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Adagrasib, Biospecimen Collection and Computed Tomography in people with Advanced Lung Non-Small Cell Carcinoma and Stage III Lung Cancer AJCC v8, run by Roswell Park Cancer Institute at 1 site in United States.

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 16 inclusion and 13 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: opening soon, as of the sponsor's last update on 2 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression free survival (PFS) (time frame: From enrollment to the loading phase and documentation of disease progression or death, at 12 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 2 Sep 2026.
