About this study
Official title: Phase II Study of Zanzalintinib in Men With Aggressive Variant Prostate Cancer (NAPOLEON Study)
This is a multi-center single arm phase II study to evaluate the antitumor activity of zanzalintinib 60mg orally (PO) once daily in subjects with AVPC. Zanzalintinib may continue until radiographic progression (or beyond), intolerable adverse events, or withdrawal of consent. As long as the subject is clinically stable, subjects may receive study treatment even after radiographic progression, until they are no longer clinically benefiting from the study treatment in the opinion of the treating Investigator, or they need subsequent systemic anticancer treatment or other urgent tumor directed medical intervention to prevent life-threatening complications.
This study will use a 2-stage group-sequential design for enrollment. The first stage will consist of enrolling 15 subjects. No more than 5 of the first 15 subjects can have received chemotherapy in the castrate- resistant setting.
- Conditions
- Aggressive Variant Prostate Carcinoma

What is being measured
The primary outcome is the main question the study is designed to answer.
Radiographic progression free survival (rPFS)
For soft tissue lesions, rPFS is defined as the date of Cycle 1 Day 1 to date of radiologic progression of soft tissue lesions per RECIST 1.1 or death whichever occurs first.
Measured: 6 months
Radiographic progression free survival (rPFS)
For bone lesions, rPFS is defined as the date of Cycle 1 Day 1 to date of progression of bone lesions per PCWG3 criteria or death whichever occurs first.
Measured: 6 months
Secondary outcomes (6)
Adverse Events
Safety of the zanzalintinib will be assessed based on Common Terminology Criteria for Adverse Events (CTCAE) version 5.0
Measured: 4 years
Overall Survival
Overall survival (OS) will be measured from date of registration to date of death from any cause censored at the date of last follow-up.
Measured: 4 years
Objective response rate (ORR)
ORR will be the proportion of patients with measurable disease achieving either a confirmed complete response or a partial response per RECIST 1.1 for patients with measurable disease.
Measured: 4 years
Duration of response (DoR)
DOR will be measured from the time a partial response or complete response is first noted until the date of progression as defined by RECIST version 1.1 for patients with measurable disease.
Measured: 4 years
Quality of life (QOL)
QOL will be assessed by changes in FACT-P. The response scale is a 5-point Likert-type scale with 0 being the minimum value and 4 being the maximum value for each individual question. The minimum score for the entire questionnaire is 0 and the maximum score is 156. The higher the score, the better the quality of life.
Measured: 4 years
Time to first subsequent anti-cancer therapy or death
Time to first subsequent anti-cancer treatment will be defined as the time from the start of a zanzalintinib to the start of the next line of therapy or death. Subjects alive without a next line of therapy at the end of follow-up will be censored.
Measured: 4 years

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Zanzalintinib in people with Aggressive Variant Prostate Carcinoma, run by Deepak Kilari 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 37 inclusion and 44 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 28 Aug 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 Deepak Kilari, MD (414-805-3666, dkilari@mcw.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Radiographic progression free survival (rPFS) (time frame: 6 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 28 Aug 2026.
