About this study

Official title: A Phase 2a Study to Type I-Polarized Autologous Dendritic Cell Vaccines Incorporating Tumor Blood Vessel Antigen (TBVA)-Derived Peptides in Combination With Cabozantinib in Patients With Localized Clear Cell Renal Cancer.

The purpose of this study is to estimate the probability of immune response for the combination treatment of dendritic cell vaccine with oral cabozantinib and characterize the safety profile of interventional therapy.

Read the detailed description

Participants with newly diagnosed, non-metastatic, histologically confirmed, clear cell renal cell carcinoma (ccRCC) who have elected to undergo surgical resection, will receive neoadjuvant autologous Tumor Blood Vessel Antigen (TBVA)-Dendritic Cell Vaccine intradermally every 2 weeks x 2 (days 7(+/-3) and 21(+/-3)) prior to surgery on day 31(+7) with oral cabozantinib 20 mg daily for 10 days. We hypothesize that treated renal tumors will demonstrate maturation and organization of the tumor endothelium with normalization of endothelial markers and formation of tertiary lymphoid structure capable of promoting specific T-cell induction.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Autologous alpha-DC1/TBVA vaccineBiological

    Dendritic cells (DC) are derived from autologous (the subject's own) mononuclear cells in the peripheral blood obtained from the PRBC. In this case, "biologic product" and "biologic substance" are the same. The vaccine will be manufactured in the HCC-IMPCL, under cGMP conditions.

  • CabozantinibDrug

    Also called Cometriq, Cabometyx

    Cabozantinib tablets are supplied as film coated tablets containing cabozantinib malate equivalent to 20 mg and 60 mg of cabozantinib and contain microcrystalline cellulose, lactose anhydrous, hydoxypropyl cellulose, croscarmellose sodium, colloidal silicon dioxide, magnesium stearate and Opadry® yellow. The 60 mg tablets are oval and the 20 mg tablets are round. Doses of 40 mg will comprise two 20-mg tablets.

What is being measured

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

  1. Probability of immune response

    Proportion of HLA-A2+ ccRCC patients that exhibit improved peripheral blood CD8+ T cell responses against 3 or more vaccine-inclusive peptide epitopes (DLK1, EphA2, HBB, NRP1, RGS5, TEM1) after active vaccination with Type I-polarized autologous dendritic cell (αDC1) vaccine with concomitant oral cabozantinib (IFN-γ ELISPOT).

    Measured: Up to 48 months

  2. Safety profile of interventional therapy - Adverse Events

    Proportion of patient reported symptoms and Dose Limiting Toxicities (DLT) for specific adverse events per NCI CTCAE v5.0.

    Measured: Up to 48 months

  3. Safety profile of interventional therapy - reduction in CD31+

    Proportion of RCC patients that exhibit greater than 30% reduction in CD31+ blood vessel content from baseline biopsy.

    Measured: Up to 48 months

  4. Reduction in tumor vascularity

    Proportion of RCC patients that exhibit greater than 30% reduction in CD31+ blood vessel content from baseline biopsy.

    Measured: Baseline; Up to 48 months

Secondary outcomes (1)
  1. Markers of vascular normalization

    Change in presence of mature CD31+ (HES1+) blood vessels with tightly approximated abluminal SMA+ pericytes and the lack of immature CD31+ blood vessels with loosely-approximated NG2+ pericytes before and after treatment.

    Measured: Baseline; Up to 48 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Autologous alpha-DC1/TBVA vaccine and Cabozantinib in people with Carcinoma, Renal Cell, run by Jodi Maranchie 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 17 inclusion and 36 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 7 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 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 Morgan Pokora, RN (412-623-4886, pokoraml3@upmc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Probability of immune response (time frame: Up to 48 months). The study lists 4 primary outcomes in all. 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 NCT05127824, which also lists 1 linked publication.

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 7 Jul 2026.
