Brief Summary:
The main purpose of this study to determine the safety of an experimental medicine called 131I-MIP-1095. 131I-MIP-1095 is an investigational drug, meaning it has not been approved by the U.S. Food & Drug Administration (FDA).

Condition or disease Intervention/treatment Phase
Prostate Cancer Metastatic Castration-Resistant Prostate Cancer (mCRPC) Drug: 131I-MIP-1095 Phase 1

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 10 participants
Intervention Model: Single Group Assignment
Intervention Model Description: This is a Phase 1, open-label, single-arm, dose ascending, out-patient study to evaluate the radiopharmaceutical 131I-MIP-1095 in men with mCRPC. The study consists of three phases: Screening, Treatment, and a Follow-up Phase. The Screening Phase consists of subject evaluation for study eligibility and dosimetry assessment. The Treatment Phase consists of two parts: Part 1, dose escalation (Cohorts 1-5), and Part 2, an additional cohort at a selected optimized dose based on safety and efficacy.
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase 1, Open-Label, Dose Ascending Study to Evaluate the Safety and Tolerability of the Therapeutic Radiopharmaceutical 131I-MIP-1095 for the Treatment of Metastatic Castration-Resistant Prostate Cancer (mCRPC)
Actual Study Start Date : January 19, 2017
Estimated Primary Completion Date : January 19, 2020
Estimated Study Completion Date : January 19, 2020

Primary Outcome Measures :
  1. Maximum Tolerated Dose (MTD) [ Time Frame: 2 years ]
    This is a phase 1 dose escalation study of 131I-MIP-1095 in men with metastatic castration-resistant prostate cancer. There are a maximum of five doses under consideration. Dose escalation cohorts will be studied if acceptable toxicity is observed. A dose limiting toxicity is defined as the occurrence of any of the following drug-related toxicities during the first cycle.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Males, age ≥18 years.
  • Subjects must have histologically or cytologically confirmed adenocarcinoma of the prostate
  • Subjects must be castration resistant with evidence of progressive prostate cancer despite castrate levels of testosterone (≤ 50 ng/dL) according to the PCWG3 criteria
  • Subjects must have metastatic disease detectable by either bone scan or cross sectional imaging by CT or MRI as per the PCWG3 guidelines
  • Subjects must have progressive disease at study entry defined as 1 or more of the following 3 criteria that occurred while the subject was on androgen deprivation therapy:

    • PSA progression defined by a minimum of two rising PSA levels with an interval of ≥1 week between each determination. Subjects who received an anti-androgen as part of their primary hormonal therapy must demonstrate progression after withdrawal. The PSA value at screening should be ≥ 2 μg/L (2 ng/mL).
    • Soft tissue disease progression defined by RECIST 1.1
    • Bone disease progression defined by PCWG3 with two or more new lesions on bone scan.

Note: For subjects enrolling on the basis of soft tissue or bone progression, the baseline scan must show progression relative to a comparison scan performed during prior therapy. If the comparison scan is not available, the baseline scan report must reference the previous scan to document progression

  • Subjects who received combined androgen blockade as their first-line hormonal therapy with an antiandrogen must have shown PSA progression after discontinuing the antiandrogen for ≥ 6 weeks prior to study treatment. No washout is needed after abiraterone or enzalutamide are discontinued. First generation antiandrogens such as bicalutamide must be withdrawn if given as first-line therapy.
  • ECOG Performance status of 0-1.
  • Adequate organ reserve as evidenced by:

    1. neutrophil count ≥ 1500 μL
    2. platelet count ≥ 100,000/μL
    3. hemoglobin ≥ 9.5 g/dL
    4. total bilirubin level ≤1.5 x ULN
    5. AST and ALT ≤2.5 x ULN
    6. serum amylase ≤ ULN
    7. lipase ≤ ULN
    8. serum creatinine ≤1.5 x ULN or calculated creatinine clearance ≥ 60 mL/min (Cockroft Gault equation)
    9. clearance of 99mTc MAG3 within 1.5 x ULN and no evidence of obstruction on the scan.
  • Serum albumin of > 3.0 g/dL
  • Subjects must have received, were ineligible to receive, or refused at least one cytotoxic chemotherapy and enzalutamide or abiraterone or both enzalutamide and abiraterone.
  • Subjects must agree to use a medically acceptable method of birth control (e.g., spermicide in conjunction with a barrier such as a condom) or sexual abstinence for the duration of the study, including 30 days after the last dose of study drug. Sperm donation is prohibited during the study and for 30 days after the last dose of study drug. Female partners must use hormonal or barrier contraception unless postmenopausal or abstinent.
  • Life expectancy ≥ 6 months

Exclusion Criteria:

  • Subject has predominant histologically or cytologically confirmed neuroendocrine prostate cancer (mixed histology is permissible, as is positivity of serum CgA and CEA).

  • Subject who has not recovered from the effects of any major surgery prior to initial treatment
  • Subject has received treatment with a systemic therapeutic radioisotope (89Sr, 223Ra dichloride, 153Sm-lexidronam) or has received prior external beam radiation therapy (EBRT) of the head and/or neck.
  • Subject is currently on renal dialysis
  • Subject has started treatment with denosumab < 1 month prior to study entry. Subjects are allowed to be on bisphosphonates or denosumab provided they are on a stable dose for ≥ 4 weeks before administration of study drug

    1. any uncontrolled infection
    2. NYHA Class III or Class IV heart failure
    3. unstable angina
    4. myocardial infarction within the 6 months prior to study entry
    5. uncontrolled hypertension (systolic BP > 160 mmHg despite 2 antihypertensive medications)
    6. COPD requiring hospital admission in the year prior to study entry
    7. diabetes mellitus requiring hospital admission in the year prior to study entry
    8. chronic liver disease
