About this study

Official title: Phase I, Open-label Study to Investigate Safety, Tolerability, PK, and PD of EMD 525797 After Single and Repeated Dosing at Different Dose Levels in Subjects With Hormone-resistant Prostate Cancer With Bone Mets and Progressive Disease Following Prior CTX

This study is intended to test an experimental new drug called, EMD 525797 (Study Drug). This drug is not yet approved for sale and has only been tested in a small number of people to date (prior to this study starting another research study was carried out involving 37 healthy volunteers receiving the Study Drug). Until more is known about this Study Drug, it can only be used in research studies.

This research study is planned to answer important questions about how the Study Drug is tolerated and how it may work in patients with prostate cancer with bone metastases.

This is a small study which is expected to include 24 patients, and will be conducted in approximately 3 hospitals in Germany and 1 hospital in Brussels, Belgium. The study will last until the last patient has had their last study visit which is expected to be about 18 months in total.

What is being measured

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

  1. Number of Subjects With Dose Limiting Toxicity (DLT)

    DLT was defined using National Cancer Institute Common Toxicity Criteria for Adverse Events Version 3.0 as any Grade 3 or 4 hematological or non-hematological toxicity occurring at any dose level until the end of Week 6, and suspected to be reasonably related to the investigational product by the Investigator and/or Sponsor except for allergic/ hypersensitivity reactions and any Grade 3/4 out-of-range laboratory values without any clinical correlate, which were reversible within 7 days.

    Measured: Baseline up to 6 weeks

  2. Number of Subjects With Treatment Emergent Adverse Events (TEAEs), Serious TEAEs and Related TEAEs

    An AE was defined as any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug or worsening of pre-existing medical condition, whether or not related to study drug. A serious adverse event (SAE) was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. Treatment-emergent are events between first dose of study drug that were absent before treatment or that worsened relative to pre-treatment state. TEAEs include both Serious TEAEs and non-serious TEAEs.Treatment-related are events which had causal relationship to study drug as assessed by the Investigator and were suspected to be reasonably related to the study drug.

CR: defined as disappearance of all target and all non-target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. PR: defined as at least a 30% decrease in sum of longest diameter of target lesions, taking as reference the baseline sum of longest diameter. PD:defined as at least a 20% increase in sum of longest diameter of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study) or unequivocal progression of existing non-target lesions. SD: defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum of longest diameter while on study.

    PFS PCWG1 criteria: time from the day treatment is initiated up to progression (for subject's whose prostate specific antigen [PSA] level did not decrease after baseline, progression defined as 50% PSA increase relative to baseline; for subject's whose PSA decreased after baseline, progression defined as 50% PSA increase relative to nadir [smallest PSA value post-baseline]. Progression was confirmed if progression criterion was met in next 2 assessments as well.) PFS PCWG2 criteria: time from study entry to disease progression or death. Progression was defined as first appearance of progression according to PSA (for subject's whose PSA decreased after baseline, progression was defined as 25% PSA increase relative to nadir. Progression was confirmed if another assessment measured at least 3 weeks later met the criterion as well; for subject's whose PSA did not decrease after baseline, progression was defined as 25% PSA increase relative to baseline assessed 12 weeks after baseline).

BPI-sf has 4 questions that assess pain intensity (worst, least, average, right now) and 7 questions that assess impact of pain on daily functions (general activity, mood, walking ability, normal work, relations with other people, sleep, enjoyment of life). Each question is answered on a scale ranging from 0 to 10;'0=No pain and 10=Pain as bad as you can imagine'.Total score is reported as average of individual questions ranges from 0 to 10, with lower scores being indicative of less pain or pain interference.Data was not available for "EMD 525797 250 mg" arm for FUP Weeks 15, 19, 23, 27, 31, 35, 39, 43, 47, 51, 55, 59, 63, 67, 71, 75 and "EMD 525797 1000 mg" arm for FUP Weeks 47, 51, 55, 59, 63, 67, 71 and "EMD 525797 1500 mg arm" for FUP Weeks 35, 39, 43, 47, 51, 55, 59, 63, 67, 71, 75 respectively as no subjects were evaluable at the specified FUP visits.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing EMD 525797 in people with Prostate Cancer and Bone Metastases, run by Merck KGaA, Darmstadt, Germany at 4 sites in 2 countries.

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 9 inclusion and 18 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: finished, as of the sponsor's last update on 2 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Germany, Belgium. 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?

Yes. Results are posted in the registry (first posted 2 Aug 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Subjects With Dose Limiting Toxicity (DLT) (time frame: Baseline up to 6 weeks). The study lists 10 primary outcomes in all. 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 NCT00958477, 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 Aug 2017.
