Trial summary

The death of prostate cancer patients is mainly due to metastatic castration-resistant prostate cancer. Though some new therapies has been tried to prolong the life-span of mCRPC patients, a dilemma was encountered for the drug-resistance. Read more about this study

About this study

Official title: Prospective Pilot Clinical Trial of Ac225-PSMA Radioligand Therapy of Metastatic Castration-resistant Prostate Cancer

The death of prostate cancer patients is mainly due to metastatic castration-resistant prostate cancer. Though some new therapies has been tried to prolong the life-span of mCRPC patients, a dilemma was encountered for the drug-resistance. The PSMA RLT has been tested its efficacy and safety for the therapy of these patients. In our clinical trial, a new PSMA ligand will been used to be labeled with Ac225. This will be a prospective pilot clinical trial. 20 mCRPC patients who was incapable of 2rd ADT or chemotherapy will be recruited in this clinical tiral. The efficacy and safety of 225Ac-PSMA will be evaluated after the administration.

What is being measured

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

  1. serum PSA level

    Serum prostate specific antigen (PSA) levels was used as the main marker of efficacy evaluation, and the changes of PSA level were divided into decrease > 50%, 30% ~ 50% and < 30%.

    Measured: through study completion, an average of 1 year

Secondary outcomes (1)
  1. Adverse Events and Serious Adverse Events

    Adverse Events and Serious Adverse Events measured using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0

    Measured: through study completion, an average of 1 year.

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing 225Ac-PSMA in people with Metastatic Castration-resistant Prostate Cancer, run by Xinhua Hospital, Shanghai Jiao Tong University School of Medicine.

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 7 inclusion and 5 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 13 Jan 2020. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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 Hui Wang, Professor (86-021-25076980, wanghuishanghai@hotmaill.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

serum PSA level (time frame: through study completion, an average of 1 year). 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 NCT04225910, which also lists 15 linked publications.

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 13 Jan 2020.
