Trial summary

This is an observational study in which data from Chinese men with metastatic castration-resistant prostate cancer that has spread to the bones and who start Radium-223 therapy is studied. When tumors form in the prostate, male hormones like testosterone will cause the spread and growth of tumors. Read more about this study

About this study

Official title: China Radium-223 Safety and Effectiveness stuDy In Real World mCRPC paTients

This is an observational study in which data from Chinese men with metastatic castration-resistant prostate cancer that has spread to the bones and who start Radium-223 therapy is studied.

When tumors form in the prostate, male hormones like testosterone will cause the spread and growth of tumors. Men with prostate cancer can have hormonal or surgical treatment that lowers testosterone. But this may not stop the cancer from growing or spreading in some men. When the prostate cancer is no longer responding to therapies aimed at lowering testosterone (castration resistant) and has spread to the bones (metastatic), it is referred to as bone metastatic castration-resistant prostate cancer.

The study treatment, Radium-223 (also called Xofigo), gives off radiation that helps to kill cancer cells. It is already approved to be used for men whose prostate cancer has spread to the bone with symptoms, but not to be used for other types of tumors or for prostate cancer that has spread to other parts of the body. Sometimes, after the approval of some drugs, researchers will further study the safety of such approved treatments in patients being treated in routine clinical practice.

In this study, researchers want to learn more about the medical problems that may occur in Chinese patients after they start Radium-223 therapy, especially those problems concerning the blood and blood-forming organs. To answer this question, the researchers will observe patients who start Radium-223 as part of their routine care and also collect information of any medical problems happening after Radium-223 injections from the medical records of these patients. These medical problems may or may not be related to Radium-223 and are also known as adverse events.

The researchers will assess the percentage of men who developed medical problems concerning the blood and blood-forming organs from the start of Radium-223 injection till up to 6 months after the last Radium-223 injection.

The researchers will also collect data on the time the participants live after start of treatment, the change in pain severity, and the time between the end of Radium-223 treatment and the beginning of the following therapy against the cancer.

Besides the data collection, no further tests or examinations of any patients or any samples are planned in this study. The participants will start Radium-223 treatment as part of their routine care as prescribed by their doctors according to the recommended use. Data collection of each participant will last until the participant leaves the study or until the study ends. The study is planned to end 6 months after the last included participant receives the last injection of Radium-223.

Being tested
Radium-223 dichloride (Xofigo, BAY88-8223)

What is being measured

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

  1. Incidence of hematological adverse events

    Hematological adverse events are reported as bone marrow suppression

    Measured: From the start of administration of Radium-223 till up to 6 months after the last Radium-223 administration

Secondary outcomes (4)
  1. Incidence of other treatment-emergent Adverse events (AEs) and Serious Adverse Events (SAEs)

    Measured: From the start of administration of Radium-223 till up to 30 days after the last Radium-223 administration

  2. Overall Survival (OS)

    Measured: From the start of administration of Radium-223 till patient death due to any causes. Up to 30 months

  3. Change in pain severity

    Pain severity will be measured using the worst pain score from the Brief pain inventory short form (BPI-SF) questionnaire. The BPI-SF is a self-administered questionnaire with 11 items designed to evaluate the intensity of, and the impairment caused by pain. Four items measure pain intensity using 0 ("no pain") to 10 ("pain as bad as you can imagine") numeric rating scales, and 7 items measure the level of interference with function caused by pain using 0 (no interference) to 10 (complete interference) rating scales.

    Measured: From the start of administration of Radium-223 till up to 6 months after the last Radium-223 administration

  4. Time interval from the last administration of Radium-223 to the initiation date of next anti-cancer therapy

    Measured: From the last administration of Radium-223 till up to 6 months

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted29 Mar 2022
  2. Study start15 Sep 2022
  3. Primary completion28 Apr 2023
  4. Study completion30 Jun 2023

Why it stopped: Due to the changes of standard of care, the slow recruitment of participants, and the similar safety profile data on real-world use of Radium-223 in China has been published.

Questions about this trial

What is this clinical trial studying?

An observational study of Metastatic Castration-resistant Prostate Cancer and Bone Metastases, run by Bayer 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 5 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: stopped early, 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.

Are results available for this study?

The study was stopped early (reason given: Due to the changes of standard of care, the slow recruitment of participants, and the similar safety profile data on real-world use of Radium-223 in China has been published.). 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?

Incidence of hematological adverse events (time frame: From the start of administration of Radium-223 till up to 6 months after the last Radium-223 administration). 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 22 Sep 2023.
