Brief Summary

This study will develop a first-in-man CTC-based molecular taxonomy of CRPC in the context of novel AR-directed therapies, categorize different patterns of resistance in this disease setting, and desc...

Detailed Description

The study will construct a multi-center clinical database of men before and after treatment with abiraterone acetate, enzalutamide, and taxane chemotherapy, and will comprehensively analyze CTC DNA fo...

Eligibility Criteria

Inclusion

  • Histologically confirmed diagnosis of adenocarcinoma of the prostate. Pure small cell or neuroendocrine tumors of the prostate are not permitted.
  • Clinical or radiographic evidence of metastatic disease.
  • Planned therapy with either enzalutamide and/or abiraterone acetate within the coming 6 weeks
  • Castrate levels of testosterone (\<50 ng/dl) at most recent assessment and/or documented ongoing Androgen Deprivation Therapy for at lease three months.
  • Evidence of disease progression on or following most recent therapy as evidenced by at least one of the following:
  • Radiographic evidence of disease progression as defined by one or more new bone scan lesions that is not consistent with flare/healing, or growth of soft tissue/visceral metastases to greater than one centimeter (cm) in longest diameter (2 cm shortest diameter for lymph nodes).
  • Clinical progression as defined by the treating physician (such as pain progression)
  • Consecutive PSA rises meeting PSA progression criteria as determined by PCWG2 criteria (increase that is \>25% and \>2 ng/mL above the nadir, and which is confirmed by a second value 3 or more weeks later)
  • At least two of the following high risk features during screening for rapid disease progression:
  • Anemia with a hemoglobin \<12.0 g/dl
  • Elevated alkaline phosphatase above the institution upper limit of normal
  • High lactate dehydrogenase (LDH) above the upper limit of normal
  • Prior therapy with enzalutamide, abiraterone acetate, or orteronel. Patients are not permitted if they are continuing on the same therapy or restarting a therapy that they have been exposed to in the past.
  • Presence of visceral metastasis on imaging
  • Presence of clinically significant pain requiring opioid analgesia
  • Patients with a Cellsearch CTC \> 5 cells per 7.5 mL whole blood (if available as standard of care) are eligible without additional high risk features
  • PSA doubling time under 3 months on most recent therapy
  • Radiographic progression at entry based on new lesion(s) in bone, soft tissue, or visceral metastases
  • Age \> 18 years.
  • Ability to understand and the willingness to sign a written informed consent document.

Exclusion

  • History of intercurrent or past medical or psychiatric illness that would make participation in a blood drawing protocol difficult or not feasible at the discretion of the principal investigator or co-investigator(s).
  • Treatment with an anthracycline or mitoxantrone within 1 week of CTC collection
  • Prior docetaxel in the castration resistant metastatic setting. Patients treated with docetaxel for metastatic castration sensitive disease will be eligible.
  • Unwillingness to be followed longitudinally for serial CTC biomarker studies.
