About this study

Official title: Phase I Study Using EUCLIDIAN Robotic Assistance During Prostate Brachytherapy

A robotic brachytherapy device will be used to assist physicians in performing seed implantation to the prostate. EUCLIDIAN is the first robotic system designed to allow automatic placement of radioactive seeds by robot and thus reduce operator dependence. The clinical study is designed to evaluate the dosimetric quality, accuracy and patient self-reported quality of life scores after robotic brachytherapy.

Read the detailed description

EUCLIDIAN (Endo-Uro Computed Lattice for Intratumoral Delivery, Implantation, Ablation with Nanosensing)

The dose-volume histogram parameters of robotic brachytherapy will be compared to historical controls of the study institution. Short-term (<1 yr) health-related quality of life (HRQoL) and changes will be assessed using FACT-P and IPSS self-report questionnaires.

What is being measured

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

  1. Coverage of the prostate by the prescribed radiation dose at V100

    The principal endpoint is the dose-volume histogram (DVH) measured at V100 (percent volume of the target receiving the intended dose). These values will also be compared retrospectively to those in the conventional group. Improved quality will be demonstrated by increased V100 in the protocol patients.

    Measured: Day 0 and Day 30 post-implant

Secondary outcomes (3)
  1. Coverage of the prostate by the prescribed radiation dose at D90

    The secondary endpoint is the dose-volume histogram (DVH) measured at D90 (dose to 90% of the target volume). These values will also be compared retrospectively to those in the conventional group.

    Measured: 12 months post-treatment

  2. Functional Assessment of Cancer Therapy-Prostate (FACT-P)

    Patient self-reported, health-related, quality of life measures using the Functional Assessment of Cancer Therapy-Prostate (FACT-P) self-report questionnaire. FACT-P instruments prior to treatment (T0), 1 month (T1), 3 months (T3), 6 months (T6) and 12 months (T12) following treatment with robot-assisted brachytherapy.

    Measured: 12 months

  3. International Prostate Symptom Score (IPSS)

    Patient self-reported, health-related, quality of life measures using the International Prostate Symptom Score (IPSS) self-report questionnaire. IPSS instruments prior to treatment (T0), 1 month (T1), 3 months (T3), 6 months (T6) and 12 months (T12) following treatment with robot-assisted brachytherapy.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing EUCLIDIAN Robot in people with Prostate Cancer, run by Sidney Kimmel Comprehensive Cancer Center at Thomas Jefferson University 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 10 inclusion and 12 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: stopped early, as of the sponsor's last update on 2 May 2025. 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?

The study was stopped early (reason given: Slow accrual). Results are not available in the source record.

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?

Coverage of the prostate by the prescribed radiation dose at V100 (time frame: Day 0 and Day 30 post-implant). 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 NCT01341288, 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 2 May 2025.
