NCT03574571

Brief Summary

The purpose of this study is to compare any good and bad effects of using radium-223 along with docetaxel chemotherapy treatment versus using docetaxel alone. Earlier studies helped show that the combination is safe, but the combination has not been proven to work better than either drug alone. The goal of this study is to find out if combining docetaxel and radium-223 is better than giving either drug by itself.

Gender Eligibility DetailsProstate
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Willing and able to provide written informed consent (ICF) and HIPAA authorization for the release of personal health information. A signed informed consent must be obtained before screening procedures are performed.
  • NOTE: HIPAA authorization may be either included in the informed consent or obtained separately.
  • Males 18 years of age and above
  • Histological or cytological proof of prostate cancer
  • Documented progressive mCRPC based on at least one of the following criteria:
  • PSA progression defined as 25% increase over baseline value with an increase in the absolute value of at least 1.0 ng/mL that is confirmed by another PSA level with a minimum of a 1 week interval and a minimum PSA of 1.0 ng/mL.
  • Soft-tissue progression defined as an increase ≥ 20% in the sum of the LD of all target lesions based on the smallest sum LD since treatment started or the appearance of one or more new lesions.
  • Progression of bone disease (evaluable disease) or two or more new bone lesions by bone scan.
  • Two or more bone lesions
  • ECOG 0- 1
  • Normal organ function with acceptable initial laboratory values within 14 days of randomization:
  • Albumin \> 30 g/L
  • ANC ≥ 1.5 x 10\^9/L
  • Hemoglobin ≥ 10 g/dL
  • Platelet count ≥ 100 x 10\^9/L
  • +9 more criteria

You may not qualify if:

  • Received any other investigational therapeutic agents or other anticancer therapies within 4 weeks prior to randomization.
  • °Note: If this requirement to have a washout of 2 weeks or 5 half-lives prior to randomization causes potential treatment delay due to Radium-223 importation timelines, the PCCTC must be contacted at pcctc@mskcc.org to request approval to randomize the subject prior to the completion of the washout. Requests for early randomization must be accompanied by written assurance by the site that the washout will be completed prior to treatment start.
  • Received external beam radiotherapy within the 4 weeks prior to randomization.
  • ° Note: If prolonging randomization to complete EBRT washout causes potential treatment delay due to Radium-223 importation timelines, the PCCTC must be contacted at pcctc@mskcc.org to request approval to randomize the subject prior to the completion of the washout. Requests for early randomization must be accompanied by written assurance by the site that the washout will be completed prior to treatment start.
  • Has an immediate need for external beam radiotherapy.
  • Has received any systemic bone-seeking radiopharmaceutical in the past.
  • Has received any prostate cancer directed chemotherapy in the castration resistant setting. Subjects who have received up to 6 prior doses of docetaxel in the castration sensitive setting are permitted if they have not experienced disease progression within 36 weeks of last treatment with docetaxel.
  • Has received four or more systemic anticancer regimens for mCRPC.
  • Treatment with docetaxel or abiraterone for non-castrate metastatic disease is permissible and does not count towards the lines of therapy for mCRPC
  • A 'line' is a regimen. Combinations of hormones and other types of therapies count as single lines.
  • Has known Grade ≥3 docetaxel-related toxicities or docetaxel toxicity related dose interruption or discontinuation.
  • Has received blood transfusions or growth factors within the last 4 weeks prior to randomization.
  • Symptomatic nodal disease (i.e., scrotal, penile, or leg edema).
  • Has visceral metastases with ≥ 3 lung and/or liver metastases or individual lesion ≥2 cm, as assessed by CT scan or MRI of the chest/abdomen/pelvis within the last 8 weeks prior to randomization.
  • Symptomatic loco-regional disease that causes ongoing Grade 3 or Grade 4 urinary or rectal symptoms.
  • +9 more criteria
