Study Description

Brief Summary:

To determine the dose of continuous daily oral lovastatin needed to achieve MYC [v-myc myelocytomatosis viral oncogene homolog (avian)] down-regulation in prostatectomy specimens in intermediate-/high-risk localized prostate cancer patients.

Condition or disease	Intervention/treatment	Phase
Prostate Cancer	Drug: Lovastatin	Not Applicable

Detailed Description:

Pharmacodynamic Phase 0 trial of pre-prostatectomy lovastatin to downregulate MYC in localized prostate cancer.

Rationale: Based on available clinical and preclinical data, the investigators theorize that high-dose lovastatin therapy will decrease MYC levels in human prostate cancers shown to have MYC overexpression on biopsy.

Experimental Methods: The investigators propose a prospective, dose-finding pharmacodynamic study of lovastatin in intermediate/high-grade localized prostate cancer. The study will involve 30 eligible patients with localized prostate cancer with a Gleason sum of 7 to 10 who elect to undergo prostatectomy at Johns Hopkins. Five eligible men will be scheduled to receive oral lovastatin following a four times a day schedule, at the starting dose of 12 mg/kg/day. Patients will receive 2 weeks (14 days) of daily oral lovastatin prior to surgery. Following an initial safety monitoring period of a month, the investigators enroll at the next dose level (20 mg/kg/day). Similar dose de-escalation will continue over three more dose levels (1, 4 and 8 mg/kg/day) until 25 patients total are enrolled. Following surgery, prostatectomy specimens will undergo MYC immunohistochemistry (IHC) and compared to MYC IHC from matched biopsy samples. Pharmacodynamic efficacy (PE) will be defined as greater than 60% inhibition of MYC expression by IHC in greater than 60% of patients in prostatectomy tumor specimens compared to the matched biopsy.

Expected Results: The investigators expect lovastatin will enforce the downregulation of MYC levels in prostatectomy samples as compared to pre-lovastatin treatment core biopsy samples. The investigators also expect little toxicity to patients as reported in prior phase I and II trials using similar doses of lovastatin.

Arms and Interventions

Arm

Intervention/treatment

Experimental: Lovastatin; After informed consent and central pathology review of the core prostate biopsy, eligible patients who decide to undergo prostatectomy at Johns Hopkins will be scheduled to receive po lovastatin following a four times a day schedule, at the starting dose of 20 mg/kg/day. Following an initial period of monitoring for safety at this entry dose level of one month, we will then accrue patients to dose de-escalation (to 1, and 10 mg/kg/day) cohorts.

Drug: Lovastatin; oral qd varying dose escalations/de-escalations; Other Name: Altoprev®; Mevacor®

5. Number of Participants With Target Inhibition of MYC and Increased Apoptosis and Proliferation [ Time Frame: 1 year ]
   Number of participants with target inhibition of MYC and markers of increased apoptosis (cleaved caspase-3) and proliferation (Ki-67).
6. Study Compliance as Assessed by Number of Participants Who Follow All of the Study Rules. [ Time Frame: 1 year ]
7. Number of Participants With MYC Downregulation [ Time Frame: 1 year ]
   Number of participants with MYC downregulation after high-dose lovastatin.

Eligibility Criteria

• Ages Eligible for Study: 18 Years to 100 Years (Adult, Older Adult)
• Sexes Eligible for Study: Male
• Accepts Healthy Volunteers: No

Criteria

Inclusion Criteria:

1. Adenocarcinoma of the prostate, without evidence of spread beyond to lymph nodes, bone, or visceral organs, stage T1c or higher.
2. Tumor Gleason sum of 7 (4+3 and 3+4 allowed) in at least one core, after central review of prostate biopsy at Johns Hopkins. However, in accordance with standard clinical practices, adenocarcinoma must be present in at least two discrete biopsy sections ( may vary in Gleason score).
3. Age ≥18 years of age.
4. Radical prostatectomy scheduled at Johns Hopkins.
5. Willingness to sign and ability to understand informed consent.
6. No history of treatment with any statin-class medication within 6 months of entry into the trial.
7. ECOG (Eastern Cooperative Oncology Group) performance status 0-1.
8. Adequate bone marrow, hepatic, and renal function as determined by:

WBC (white blood cells) >3,500 cells/mm3 ANC (absolute neutrophil count) >1,500 cells/mm3 Hemoglobin >9 g/dl Platelet count >100,000 cells/mm3 Serum creatinine < 2.6 mg/dl Serum bilirubin <2 mg/dl ALT (alanine aminotransferase), AST (aspartate aminotransferase), and Alkaline Phosphatase <2 times the upper limit of normal Triglycerides and total cholesterol <3 times the upper limit of normal

Exclusion Criteria:

1. Patients with evidence of metastatic prostate cancer, including bone, visceral, brain, and lymph node metastases.
2. Other histologic prostate cancers, including ductal, sarcomatous, lymphoma, small cell, and neuroendocrine tumors.
3. Uncontrolled medical conditions that could potentially increase the risk of toxicities or complications of this therapy including active liver disease, unexplained persistent elevation of serum transaminases, or medications that interfere with the metabolism of lovastatin, or gastrointestinal disease that would limit the ability to swallow or take oral medications or absorb them.
4. Concurrent malignancy other than prostate cancer.
5. Inability to provide informed consent.
6. Concomitant use of azole antifungals, cyclosporine, clarithromycin, erythromycin, fibric acid derivatives, lopinavir/ritonavir, niacin, ritonavir/saquinavir
7. Prior chemotherapy, radiation therapy, biologic therapy, or immunotherapy for prostate cancer.
8. Poor performance status (ECOG >1).
9. Prostatectomy at other hospital other than Johns Hopkins.
10. Prior history of allergy or severe reaction to statins or statin derivatives.
