[18F] Dihydro-testosterone Pet and MR Imaging In Patients With Localized Prostate Cancer

Lead Sponsor:

Memorial Sloan Kettering Cancer Center

Conditions:

Prostate Cancer

Localized Prostate Cancer

Eligibility:

MALE

21-79 years

Phase:

PHASE1

Brief Summary

The purpose of this study is to test the ability of a new PET scan radiotracer, called FDHT (stands for \[18F\] Dihydro-Testosterone), to better find and monitor prostate cancer. Radiotracers are a ty...

Eligibility Criteria

Inclusion

  • Male aged 21 years or older and below 80 years of age.
  • Signed written informed consent and willingness to comply with protocol requirements.
  • Histologically confirmed diagnosis of prostate cancer.
  • Staging imaging workup including a baseline MRI of the prostate and pelvis performed at MSKCC.
  • Baseline imaging to rule out distant metastatic disease (99mTc bone scan, NaF PET, total body MRI, or CT chest/abdomen/pelvis)
  • Karnofsky performance status ≥ 70
  • Clinical criteria required to be eligible:
  • a. One of the following i.Pre-treatment PSA ≥10 ng/dL, OR ii. Clinical T-stage assessed by digital rectal exam of ≥T2a, OR ii . Radiographic ≥T3a on MRI, OR iv. Gleason score of ≥3+4=7 c. Visible intraprostatic tumor foci ≥1 cm in largest dimension on T2-weighted images based on initial pre-treatment MRI
  • Physician recommendation of ADT.

Exclusion

  • Metastatic disease on standard staging imaging (beyond regional lymph node involvement).
  • o Absence of metastatic disease (beyond regional lymph node involvement) as defined by a negative bone scan, NaF PET, CT chest/abdomen/pelvis, or total body MRI.
  • Prior treatment of the prostate gland for malignant conditions (surgery, cryotherapy, radiotherapy, or photodynamic therapy).
  • Physician prescription of androgen receptor antagonist therapy (examples: bicalutamide, flutamide, or enzalutamide) during time of protocol scans.
  • o Note: ADT consists of chemical castration (i.e. degarelix) to remove endogenous DHT. Androgen receptor antagonists will bind to the androgen receptor and inhibit FDHT from binding.
  • Patients receiving testosterone supplementation .
  • Any contraindication to baseline MRI based on departmental MR questionnaire, or inability to cooperate for an MRI scan.
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to FDHT.
  • Hepatic laboratory values:
  • Bilirubin \>1.5 x ULN (institutional upper limits of normal)
  • AST/ALT \>2.5 x ULN
  • Albumin \<2 g/dL
  • Creatinine \>2.5 mg/dL
  • Calcium \>11 mg/dL
  • Other serious illness(es) which might preclude completion of this study or interfere with determination of causality of any adverse effects experienced in this study.
