About this study

The purpose of this study is to evaluate the effectiveness and safety of 177Lu-PSMA-0057 in metastatic prostate cancer.

Read the detailed description

This study is a prospective, single arm, open exploratory clinical study. Ten patients with metastatic prostate cancer confirmed by histopathology will be included in the group.

Before conducting any research specific screening evaluation, participants must sign an Informed Consent Form (ICF). All screening procedures must be completed within 28 days before the first day of administration (D1).

During the screening period, patients will be scanned using 68Ga-PSMA-0057 to determine the PSMA expression status. It is recommended to perform a 68Ga-PSMA-0057 scan after confirming all other qualification requirements.

The successfully screened subjects underwent baseline examination 1 day before administration (D-1) (The laboratory examination and ECG are limited to the examination data within 7 days of our hospital, while imaging is limited to the data within 28 days of our hospital), and were confirmed to meet the enrollment requirements before enrollment. The enrolled subjects will be administrated with 177Lu-PSMA-0057, and then enter the post administration observation phase while completing safety checks. After the safety evaluation, the subjects may temporarily leave the research institution.

At the end of the second treatment cycle, the improved RECIST version 1.1/PCWG3 criterion was used to rate the tumor remission. Perform CT/MRI and other imaging examinations at the screening period, the end of the second treatment cycle, and at the end of treatment/early termination of the visit (those who have undergone CT/MRI and other imaging examinations within 28 days before the end of treatment/early termination of the visit may be exempted). Perform prostatic specific antigen(PSA) assessment at the end of the second treatment cycle to determine and confirm PSA response.

Conduct comprehensive safety checks at baseline, end of treatment visit/early termination visit, including vital signs, physical examination, laboratory examination (including blood routine, blood biochemistry, coagulation function, urine routine), total serum PSA level, serum testosterone measurement, ECG examination, and echocardiography.

Safety check after administration: ① ECG examination: Weekly blood routine check after administration in cycles 1 and 2; ② Blood routine examination: After the first and second cycles of administration, weekly blood routine examination is conducted; ③ Blood biochemistry, coagulation function, and urine routine examination: After administration in the first cycle, blood biochemistry, coagulation function, and urine routine examination should be rechecked every week, and once at the end of the second cycle; ④ Echocardiography: Recheck once at the end of the second cycle.

What is being measured

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

  1. PSA dynamic

    PSA50 response rate, PSA90 response rate: PSA response determined by measuring a decrease of ≥ 50% or ≥ 90% in PSA levels from baseline to baseline, and reassessed at least 3 weeks later. The proportion of patients with a decrease of ≥ 50% or 90% in PSA response rate at a certain time point is usually used as an evaluation indicator.

    PSA undetectable rate: refers to the percentage of patients with PSA detectable at baseline (≥ 0.2ng/mL) but undetectable during the study period (<0.2 ng/mL).

    Measured: 2 weeks

Secondary outcomes (1)

  1. Radiographic Progression Free Survival，rPFS

    The response status of tumors will be evaluated using the modified RECIST version 1.1/PCWG3 standard: solid tumors typically use the conventional RECIST 1.1 standard to evaluate tumor remission or progression. Advanced prostate cancer has a high proportion of bone metastases. According to RECIST 1.1, bone metastases are usually classified as unmeasurable lesions and are not evaluated as target lesions. Instead, bone scans are evaluated using the PCWG3 standard.

    RPFS is defined as the time from the random date to the occurrence of imaging progression or death from any cause, whichever occurs first. Imaging progression includes the evaluation of the progression of primary lesions, non regional lymph node invasion, soft tissue metastasis, and bone metastasis according to the RECIST 1.1 and PCWG3 standards, and is determined by the central reviewer or investigator review.

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing 177Lu-PSMA-0057 in people with Metastatic Prostate Cancer, run by Nanjing First Hospital, Nanjing Medical University at 1 site in China.

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 21 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 22 Sep 2023. 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 China. 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?

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 Feng Wang (02552271491, fengwangcn@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

PSA dynamic (time frame: 2 weeks). 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 NCT06050239.

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 22 Sep 2023.
