Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Estimated)

Enrollment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
PSA response
Time Frame: 12 months
in term of PSA decline of ≥ 50% from baseline value
12 months
Emergence of therapy toxicity
Time Frame: 12 months
in terms of pathological (Grade 3) reduction of values of blood count (hemoglobin decreased <8.0 g/dL; <4.9 mmol/L; <80 g/L; platelet count decreased <50,000 - 25,000/mm3; <50.0 - 25.0 x 10e9 /L and white blood cell decreased <2000 - 1000/mm3; <2.0 - 1.0 x 10e9 /L. ), kidney (creatinine increased > 3.0 x baseline or >3.0 - 6.0 x upper limit of normal (UNL)) and liver functions (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and GGT increased >5.0 - 20.0 x ULN if baseline was normal or >5.0 - 20.0 x baseline if baseline was abnormal; albumin <2 g/dL or <20 g/L; bilirubin increased >3.0 - 10.0 x ULN if baseline was normal or >3.0 - 10.0 x baseline if baseline was abnormal and lactate dehydrogenase increased > ULN.), assessed by Common Terminology Criteria for Adverse Events (CTCAE), version 5.0.
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure

Time Frame
Time to PSA value progression
Time Frame: 18 months
to evaluate progression free survival
18 months
androgen deprivation therapy- and other treatment-free survival
Time Frame: 18 months
analyze the time until the start of androgen deprivation therapy
18 months
Evaluation of life quality of the treated patients
Time Frame: 18 months
Using the questionnaires: FACT-P, EORTC QLQ
18 months
Assess time to imaging progression
Time Frame: 18 months

18 months
Quantification of circulating free tumor DNA
Time Frame: 18 months
Quantification of circulating free tumor DNA (ctDNA), enumeration of circulating tumor cells (CTCs) before and following [177Lu]Lu-PSMAI&T-RLT and analyse molecular changes in liquid biopsy markers following [177Lu]Lu-PSMAI&T-RLT.
