Standard Dose Versus High Dose and Versus Extended Standard Dose Radium-223 Dichloride in Castration-resistant Prostate Cancer Metastatic to the Bone

June 30, 2019 updated by: Bayer

A Three Arm Randomized, Open-label Phase II Study of Radium-223 Dichloride 50 kBq/kg (55 kBq/kg After Implementation of NIST Update) Versus 80 kBq/kg (88 kBq/kg After Implementation of NIST Update), and Versus 50 kBq/kg (55 kBq/kg After Implementation of NIST Update) in an Extended Dosing Schedule in Subjects With Castration-resistant Prostate Cancer Metastatic to the Bone

This study will assess different doses and regimens of radium-223 dichloride on the incidence of symptomatic skeletal events. Eligible subjects must have castration resistant prostate cancer with 2 or more skeletal metastases documented within 8 weeks of randomization. Subjects will be randomized to one of 3 treatment arms in a 1:1:1 fashion: a standard regimen of radium-223 dichloride of 50 kBq/kg (55 kBq/kg after implementation of NIST update) injections every month for 6 months, a high dose regimen of 80 kBq/kg (88 kBq/kg after implementation of NIST update)injections every month for 6 months or an extended duration regimen of 50 kBq/kg (55 kBq/kg after implementation of NIST update) injections every month for 12 months. Following the treatment phase, subjects will be followed up every 12 weeks for a minimum of 2 years, at which point they will enter a long term follow-up period during which they are seen every 6 months for up to 7 years after the last dose of radium dichloride. Symptomatic skeletal event and safety endpoints will be assessed at each clinic visit. Pain and analgesic use data will be collected every 4 weeks through Week 48. Additionally, radiological assessments including MRI/CT of the abdomen and pelvis and chest CT, as well as technetium-99 bone scans will be performed at Weeks 8, 16, and 24 and continue every 12 weeks thereafter until disease progression is documented in either the bone or in soft tissue. Radiological imaging will be evaluated by blinded central review.

Time Frame: From randomization to 135 SSE-FS events have been observed in comparison 1 or 75 SSE-FS events observed in comparison 2, whichever occurred last (approximately 36 months from first patient randomization)
Participants were divided in 3 groups according to baseline pain evaluation: asymptomatic subjects (WPS 0 to < 1 at baseline); mildly symptomatic subjects (WPS 1-3 at baseline); and symptomatic subjects with WPS > 3 and ≤ 7 at baseline). Pain progression was defined as the occurrence of a pain increase of 2 or more points in the average (i.e., average of 7-day assessments) "worst pain in 24 hours" score from baseline observed at 2 consecutive evaluations ≥ 4 weeks apart. Participants with insufficient applicable baseline assessments or without adequate post-baseline assessments were to be censored at the applicable baseline date.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.

Analgesic use in this study were captured via two methods: Analgesic concomitant medication case report form, where the physician records the analgesic medication prescribed to manage pain; 24 hour analgesic consumption case report form, in which all analgesic medication taken in the last 24 hours.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 10, 2014

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
March 1, 2017

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
