About this study

Official title: A Study to Evaluate the Safety and Efficacy of PV-001-DV in Combination With Infusion of PV-001-DC in Patients With Advanced Melanoma

The purpose of this arm of the study is to find the best way to give patients this investigational product and determine if it can treat advanced melanoma by stimulating the immune system. PV-001-DV is an attenuated (weakened) strain of dengue virus developed as a potential preventative vaccine for dengue fever by the US Army as Dengue Virus-1 #45AZ5. This is the first time PV-001-DV will be given to patients with melanoma. Up to 4 dose levels of PV-001-DV will tested in this arm. PV-001-DV (at the lowest dose) will be given to a group of 3 people. As each dose level is found to be safe, it will be given to another other 3 people at the next higher dose level, for a total of up to 10 people in this study. Investigators will monitor patients carefully for any harmful side effects. The side effects in people cannot be completely known ahead of time.

Patients must be progressing after having completed prior therapy with a PD-1 / PD-L1 antagonist alone or in combination with anti-CTLA-4. If the patient is positive for BRAF, the patient must have progressed on at least one BRAF inhibitor in addition to a PD-1 / PD-L1 inhibitor alone or in combination with CTLA-4 for metastatic melanoma.

Patients will have a prescribed amount of PV-001-DV injected into one of their melanoma tumors. Scans will be performed during the study at different times to see if their tumors have changed in size. Patients will also have their blood and small samples of tumors tested for changes to the immune system. After 365 days, the trial will be completed for that patient.

What is being measured

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

  1. Incidence and severity of Treatment-Emergent Adverse Events of PV-001-DV

    Treatment-Emergent Adverse Event Incidence of patients receiving intratumoral injection of PV-001-DV

    Measured: 365 days

Secondary outcomes (3)

  1. Overall Response Rate (ORR)

    Tumor response will be measured per investigator's assessment according to RECIST v1.1 and iRECIST

    Measured: 365 days

  2. Progression-Free Survival (PFS)

    The length of time during the treatment of a disease, such as cancer, that a patient lives with the disease but it does not get worse, up to the end of the study

    Measured: 365 days

  3. Overall Survival (OS)

    Overall Survival is measured from the date of enrollment to the date of death for a dead patient. If a patient is still alive or is lost to follow up, the patient will be censored at the last contact date, up to the end of the study

    Measured: 365 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Dengue Virus-1 #45AZ5 (PV-001-DV) in people with Advanced Melanoma, run by PrimeVax Immuno-Oncology Inc..

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 19 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: status not confirmed, as of the sponsor's last update on 6 Jul 2023. 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?

Results are not available in the source record.

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

Contact Bruce W Lyday ((714) 585-7485, bruce.lyday@primevax.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence and severity of Treatment-Emergent Adverse Events of PV-001-DV (time frame: 365 days). 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 NCT03989895.

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 6 Jul 2023.
