About this study

Official title: Pilot Feasibility Study of the Combination of a Personalized Therapeutic Anti-tumor Vaccine With Pembrolizumab and Standard of Care Chemotherapy in Squamous Non-Small Cell Lung Cancer and Extensive Stage Small Cell Lung Cancer

Both metastatic squamous non-small cell lung cancer (NSCLC) and extensive stage small cell lung cancer (SCLC) are incurable with current therapies, but due to mutations induced by cigarette smoke, typically express a large number of altered proteins that can be recognized as foreign by the immune system. This antigenicity is thought to explain the efficacy of pembrolizumab as either a first or second line treatment in this disease. For patients who receive chemotherapy plus immunotherapy as a first line therapy, there is sound rationale for combination treatment with immunotherapy and a therapeutic antitumor vaccine as a maintenance strategy. Regardless of PD-L1 expression in the tumor, monoclonal antibodies that block PD-1/PD-L1 interactions are effective second line therapies after chemotherapy in both NSCLC and SCLC. In addition, by targeting the immune system against tumor specific antigens using a peptide vaccine, the efficacy of pembrolizumab alone is expected to be enhanced, with an improved response rate and prolonged overall survival with no additional toxicity.

This pilot study will provide a preliminary test of the feasibility of generating a personalized, tumor neoantigen-specific therapeutic vaccine and the safety of combining it with checkpoint blockade immunotherapy.

Please note that this study originally opened with ID# 201707041 but was withdrawn due to change in standard of care chemotherapy. This study was revised and submitted as an amendment to the same IND but our IRB required it to be submitted as a new study and it received a new ID#.

What is being measured

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

  1. Safety and feasibility of the combined regimen as measured by number of participants who experience a serious adverse event

    -The descriptions and grading scales found in the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 will be utilized for all toxicity reporting.

    Measured: 30 days following the completion of treatment (estimated to be 2 years and 16 weeks)

Secondary outcomes (8)

  1. Objective response rate as measured by RECIST 1.1

    --Percentage of participants who experience a complete or partial response

    • Complete Response (CR): Disappearance of all target and non-target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm
    • Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters

    Measured: Through completion of treatment (estimated to be 108 weeks)

  2. Progression-free survival (PFS) as measured by RECIST 1.1

    • PFS is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first.
    • Progressive disease: At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progressions). Appearance of one or more new lesions and/or unequivocal progression of existing non-target lesions. Unequivocal progression should not normally trump target lesion status. It must be representative of overall disease status change, not a single lesion increase.

    Measured: Through completion of follow-up (estimated to be 7 years)

  3. Overall survival (OS)

    Measured: Through completion of follow-up (estimated to be 7 years)

  4. Clinical benefit rate (CBR)

    Measured: Through completion of treatment (estimated to be 108 weeks)

  5. Duration of response (DOR)

    Measured: Through completion of treatment (estimated to be 108 weeks)

  6. Response conversion rate (RCR)

    Measured: Through completion of treatment (estimated to be 108 weeks)

  7. Objective response rate (ORR) as measured per iRECIST

    Measured: Through completion of treatment (estimated to be 108 weeks)

  8. Progression-free survival (PFS) as measured per iRECIST

    -PFS is defined as the duration of time from start of personalized vaccine treatment (~12 weeks after baseline) to time of progression or death, whichever occurs first.

    Measured: Through completion of follow-up (estimated to be 7 years)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Pembrolizumab, NEO-PV-01 vaccine and Biopsy in people with Non Small Cell Lung Cancer and NSCLC, run by Washington University School of Medicine.

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 18 inclusion and 32 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: withdrawn, as of the sponsor's last update on 12 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety and feasibility of the combined regimen as measured by number of participants who experience a serious adverse event (time frame: 30 days following the completion of treatment (estimated to be 2 years and 16 weeks)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03166254.

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 12 Apr 2019.
