About this study

Official title: Single-arm Phase (II) Study on MR-based Hypofractionated Adaptive Image-guided Radiation Therapy for Prostate Cancer

Single-centre single-armed, non-randomized interventional phase II-study of hypofractionated image-guided radiotherapy "IGRT" with weekly magnetic resonance imagings "MRI" for personalized adaptation of the treatment plan depending on individual MR-anatomy of prostate/organ at risks "OAR" during course of IGRT.

Read the detailed description

IGRT-schedule: 20 fractions to a total dose of 60 Gy

Personalized adaption of treatment plan dependning on volume-/ and constraint-thresholds and evaluation of biomarkers (multiparametric MRI, blood, tissue, stool, urine).

Treatment at MR-Linac allowed

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Plan adaptation of Radiation Treatment in case of anatomical changesRadiation

    Image guided radiotherapy is given to 60Gy in 20 fractions. Intervention: Radiation treatment plan adaption in case of volume changes of target volume or not meeting OAR constraints due to volume changes.

Study groups in NCT03880851
Study groupRoleWhat they receive
Hypofractionated image-guided radiotherapyOtherHypofractionated image-guided radiotherapy "IGRT" to a total dose of 60 Gy (20 fractions) is performed. Weekly MRI are used to estimate volume/deformation changes of OAR and target volume. Intervention: In case of a significant change of target volume or OARs (threshold based) the radiation treatment plan is adapted on individual MR-anatomy.

What is being measured

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

  1. Number of participants with gastrointestinal "GI" and genitourinary "GU" toxicity of >/= G2

    Hypothesis: reduction of GI/GU-toxicity (CTC-criteria 4.0, RTOG) from 20% to 10% at 2 years, power 80%

    Measured: 2 years

Secondary outcomes (10)
  1. Number of participants completing at least 2 of 4 MRI-examinations during course of IGRT

    Feasibility and tolerability of completing at least 2 of 4 MRIs during treatment

    Measured: 6 months

  2. Rate of participants achieving local control

    In case of PSA progress: No evidence of local recurrence detected by MRI

    Measured: 2, 5, 10 years

  3. Rate of participants achieving regional control

    In case of PSA progress: No evidence of regional recurrence detected by MRI

    Measured: 2, 5, 10 years

  4. Rate of participants achieving Distant-metastasis-free survival "DMFS"

    No evidence of distant metastases diagnosed by cross-sectional imaging including bone scan, MRI, CT and PET

    Measured: 2, 5, 10 years

  5. Number of Participants with biochemical no evidence of disease "bNED"

    biochemical no evidence of disease according to Phoenix definition: nadir + 2ng/ml

    Measured: 2, 5, 10 years

  6. Time without secondary treatment "TWIST"

    Time without secondary treatment calculated from start of IGRT

    Measured: 2, 5, 10 years

  7. CTC-Proctitis

    CTC 4.0

    Measured: 2, 5, 10 years

  8. CTC-Incontinence

    CTC 4.0

    Measured: 2, 5, 10 years

  9. Progression-free survival "PFS"

    progression-free survival is defined as any progression (biochemical or other recurrences) or death or initiation of secondary treatment, calculation from start of IGRT

    Measured: 2, 5, 10 years

  10. Overall survival "OS"

    Overall survival is calculated from start of IGRT

    Measured: 2, 5, 10 years

Questions about this trial

What is this clinical trial studying?

A study testing Plan adaptation of Radiation Treatment in case of anatomical changes in people with Prostate Cancer, run by University Hospital Tuebingen at 1 site in Germany.

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 6 inclusion and 7 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 20 Mar 2019. 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 Germany. 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.

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 Silke Theden (+49707183420, silke.theden@med.uni-tuebingen.de), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants with gastrointestinal "GI" and genitourinary "GU" toxicity of >/= G2 (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 20 Mar 2019.
