About this study

Official title: Study of the Safety and Efficacy of Radiation Therapy (HB-001) by Alpha-particle Sources for Recurrent Malignant Solid Tumors in Japan

An intratumoral alpha particle based approach for cancer treatment using diffusion alpha-emitting radiation therapy (DaRT)

Read the detailed description

This will be a prospective, open label, single arm, controlled study, assessing the safety and efficacy of diffusing alpha emitters radiation therapy (DaRT) delivered through radioactive seeds inserted into the tumor. This approach combines the advantages of local intratumoral irradiation of the tumor, as used in conventional brachytherapy, with the power of the alpha radiation emitting atoms, that will be introduced in quantities considerably lower than radiation therapy already used in patients. Superficial lesions with histopathological confirmation of malignancy will be treated using DaRT seeds. Reduction in tumor size 70 days after DaRT insertion will be assessed. Safety will be assessed by the incidence, severity and frequency of all Adverse Events (AE).

What participants receive

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

  • HB-001Device

    Also called DaRT(Diffusing Alpha Radiation Emitters Therapy)

    An intratumoral insertion of a seed(s), loaded with Radium-224, securely fixed in the seeds. The seeds release by recoil into the tumor short-lived alpha-emitting atoms.

What is being measured

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

  1. Tumor response to HB-001

    Assessment of tumors response using the Response Evaluation Criteria in Solid Tumors (RECIST) (Version 1.1)

    Measured: 9 - 11 weeks after HB-001 seed insertion

Secondary outcomes (1)
  1. Adverse Events

    The incidence, frequency, severity and causality of adverse events related to the HB-001

    Measured: 12 weeks after HB-001 insertion

Questions about this trial

What is this clinical trial studying?

A study testing HB-001 in people with Breast Cancer and Head and Neck Cancer, run by Hekabio at 4 sites in Japan.

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 10 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 3 Jun 2022. 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 Japan. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Tumor response to HB-001 (time frame: 9 - 11 weeks after HB-001 seed insertion). 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 3 Jun 2022.
