About this study

Official title: Phase I, Open-Label Study of Dually Armored Chimeric Antigen Receptor (CAR) T Cells (TmPSMA-02) in Patients With Metastatic Castrate-Resistant Prostate Cancer (mCRPC)

This is a Phase I, open-label dose finding study to assess the safety, tolerability, manufacturing feasibility, and preliminary efficacy of TmPSMA-02 CAR T cells in patients with metastatic castrate-resistant prostate cancer (mCRPC). Up to 4 total dose levels will be evaluated using a 3+3 dose escalation design.

Read the detailed description

This is a Phase I, open-label dose finding study to assess the safety, tolerability, manufacturing feasibility, and preliminary efficacy of TmPSMA-02 CAR T cells in patients with metastatic castrate-resistant prostate cancer (mCRPC). Up to 4 total dose levels will be evaluated using a 3+3 dose escalation design as described below. Dose escalation will begin with Dose Level 1 as follows:

  • Dose Level 1 (N = 3 to 6): Subjects will receive a single dose of 5 x 107 TmPSMA-02 CAR T cells via IV infusion administration on Day 0, following lymphodepletion with fludarabine and cyclophosphamide. This dose level will be evaluated as follows:
  • If 1 DLT/3 subjects occurs, the study will enroll an additional 3 subjects at this dose level.
  • If 0 DLT/3 subjects or 1 DLT/6 subjects occur, the study will advance to Dose Level 2 (DL2).
  • In the event that 2 or more DLTs occur at Dose Level 1 (DL1), enrollment at this dose level will be stopped and Dose Level -1 (DL-1) will be opened. In Dose Level -1, subjects will receive a de-escalated dose of 1 x 107 TmPSMA-02 CAR T cells following lymphodepletion.

If 0 DLT/3 or 1 DLT/3 subjects occurs at DL-1, the study will enroll an additional 3 subjects at this dose level.

If ≥ 2 DLTs occur at any time, enrollment at this dose level will be stopped.

Dose Level 2 (N = 3 to 6): Subjects will receive a single fixed dose of 1 x 108 TmPSMA-02 CAR T cells via IV infusion on Day 0, following lymphodepletion with fludarabine and cyclophosphamide. This dose level will be evaluated as follows:

  • If 1 DLT/3 subjects occurs, the study will enroll an additional 3 subjects at this dose level.
  • If 0 DLT/3 subjects or 1 DLT/6 subjects occur, the study will advance to Dose Level 3 (DL3).
  • If 2 DLTs occur at any time, enrollment at this dose level will be stopped. If less than 6 subjects were treated at the previous dose level (DL1), additional subjects will be enrolled at that dose level to reach a minimum of 6 DLT-evaluable subjects for MTD determination.
  • Dose Level 3 (N = 3 to 6): Subjects will receive a single fixed dose of 3 x 108 TmPSMA-02 CAR T cells via IV infusion Day 0, following lymphodepletion with fludarabine and cyclophosphamide. This dose level will be evaluated as follows:
  • If 1 DLT/3 subjects occurs, the study will enroll an additional 3 subjects at this dose level.
  • If 0 DLT/3 subjects occurs, the study will still enroll an additional 3 subjects at this dose level to allow for MTD determination.
  • If 2 DLTs occur at any time, enrollment at this dose level will be stopped. If less than 6 subjects were treated at the previous dose level (DL2), additional subjects will be enrolled at that dose level to reach a minimum of 6 DLT-evaluable subjects for MTD determination.

The highest dose at which 0 or 1 DLT occurs in 6 DLT-evaluable subjects will be declared the MTD.

Retreatment Infusions:

The Retreatment Phase will remain closed until sufficient safety and persistence data is available in initial subjects, and DSMB and FDA approval to open Retreatment has been received.

Subjects who have demonstrated clinical benefit after their initial TmPSMA-02 CAR T cell infusion (e.g., minimum disease response of stable disease, etc.) may also be eligible to receive retreatment with TmPSMA-02 CAR T cells at the physician-investigator's discretion. The TmPSMA-02 retreatment dose administered must either be a) the CAR T cell dose that the subject previously received without DLTs, or b) a CAR T cell dose that is less than or equal to a dose level that has been evaluated for safety in ≥ 3 other subjects without evidence of DLTs. As retreatment infusions will not be used for formal DLT assessments/MTD determination, there are no protocol-defined staggering requirements.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing TmPSMA-02 CAR T Cells in people with Metastatic Castrate-Resistant Prostate Cancer (mCRPC), run by University of Pennsylvania 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 18 inclusion and 10 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: under way, not looking for participants, as of the sponsor's last update on 10 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 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?

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?

Number of subjects with dose limiting toxicities (DLTs) (time frame: 28 days after TmPSMA-02 CAR T cell infusion). The study lists 3 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 NCT06046040, 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 10 Aug 2026.
