About this study

Official title: PNV21-001: A Phase I Study of a Personalized Multi-Peptide Neo-Antigen Vaccine in Breast Cancer, Pre-Treated Nonsmall Cell Lung Cancer and PD1/PD-L1 Inhibitor-Refractory Melanoma

This phase I trial studies the safety of personalized neo-antigen peptide vaccine in treating patients with stage IIIC-IV melanoma, hormone receptor positive HER2 negative breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic) or does not respond to treatment (refractory) or stage III-IV non-small cell lung cancer. Personalized neo-antigen peptide vaccine is a product that combines multiple patient specific neo-antigens. Given personalized neo-antigen peptide vaccine together with Th1 polarizing adjuvant poly ICLC may induce a polyclonal, poly-epitope, cytolytic T cell immunity against the patient's tumor.

Read the detailed description

OUTLINE:

Patients receive poly ICLC intramuscularly (IM) or intratumorally (IT) once weekly in weeks when no vaccine is given. Beginning 2 weeks after starting poly ICLC, patients receive personalized neo-antigen peptide vaccine IM once every 4 weeks and nivolumab intravenously (IV) every 2 or 4 weeks. Treatment continues for 25 weeks in the absence of disease progression or unacceptable toxicity. Patients determined to have clinical benefit on a first course of treatment may repeat a 6-month course of treatment as described above. Patients then receive nivolumab IV every 2 or 4 weeks for up to 12 months in the absence of disease progression or unacceptable toxicity. Upon radiographic disease progression or completion of treatment with stable disease, patients may be offered ruxolitinib 20 mg orally twice daily for one month while continuing PD-1 inhibitor therapy. Ruxolitinib may be extended beyond one month if the treating physician believes continued treatment is of clinical benefit. Additionally, patients may undergo echocardiography (ECHO) or multigated acquisition scan (MUGA) during screening. Patients also undergo tumor biopsy, blood sample collection, and computed tomography (CT) and/or positron emission tomography (PET) throughout the study.

After completion of study treatment, patients are followed up at 24, 36, and 48 weeks. Patients who do not have disease progression and continue nivolumab monotherapy or off treatment will continue post-treatment follow up for an additional 12 months.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Neoantigen Peptide Vaccine, Nivolumab and Poly ICLC in people with Anatomic Stage IV Breast Cancer AJCC v8 and Clinical Stage IV Cutaneous Melanoma AJCC v8, run by Fred Hutchinson Cancer Center 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 38 inclusion and 24 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 22 Jul 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 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?

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 FHCC Intake (206-606-1024, hutchdoc@fredhutch.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of adverse events (time frame: 1 year post first vaccination). 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 22 Jul 2026.
