April 19, 2021 updated by: Boston Scientific Corporation

TheraSphere for the Treatment of Liver Metastases: An Open Label Trial of TheraSphere in Patients With Liver Metastases From Primary Colorectal Cancer, Neuroendocrine Cancer or Non-colorectal/Non-neuroendocrine Cancer

This study will evaluate Liver Progression Free Survival (PFS) and safety of TheraSphere treatment at doses of 120 Gy +/1 10% in patients at least 18 years of age diagnosed with metastatic disease to the liver that cannot be treated or is progressing following treatment with systemic or other liver-directed therapies.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Hepatic Progression-free Survival According to Response Evaluation Criterian in Solid Tumors (RECIST)
Time Frame: From the date of first treatment until date of first documented progression; median patient follow-up 30 months
Progression per RECIST v 1.0 is defined as at least 20% increase in the sum of the longest diameter of target lesions, taking as the reference the smallest sum of longest diameters recorded since treatment started, or unequivocal progression of existing non-target lesion or appearance of new lesions. A maximum of 5 target lesions per organ are assessed. To assess the impact of a non-systemic local therapy on progression, for the purposes of this trial, hepatic progression was defined as at least a 20% increase in the sum of the longest diameter of target hepatic lesions. Hepatic progression-free survival is the time from the day of first treatment with TheraSphere to determination of hepatic progression.
From the date of first treatment until date of first documented progression; median patient follow-up 30 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Overall Survival
Time Frame: Time from first TheraSphere treatment to death; median follow up 30 months
Duration of survival from date of first TheraSphere treatment to date of death or censored to last known date alive.
Time from first TheraSphere treatment to death; median follow up 30 months
