Safety and Efficacy Studies of Panobinostat and Bicalutamide in Patients With Recurrent Prostate Cancer After Castration
Phase I/II Randomized Trial of LBH589 (Panobinostat) at Two Dose Levels Combined With Bicalutamide (Casodex) in Men With Castration-resistant Prostate Cancer

This trial is designed to investigate the safety, dosing schedule, and efficacy of the combination treatment of Panobinostat (a histone deacetylase inhibitor) and hormone therapy for recurrent prostate cancer. This trial is at its Phase II stage. As of July 23, 2013 Arm B was closed to accrual, all the remaining slots in accrual will be allocated to Arm A.

The preclinical data indicate that Panobinostat restores the sensitivity of androgen-independent cells to bicalutamide (Casodex®) and the combination has synergistic inhibitory activity. Here, we hypothesize that treatment of castration-resistant patients with Panobinostat will enhance the response to the second line hormone therapy with bicalutamide (Casodex®). In the proposed phase I study, the maximum tolerated dose of tri-weekly, intermittent oral Panobinostat at three different dose levels (60, 90, 120 mg/week) in combination with Casodex (50mg PO) will be determined; The following phase II study will evaluated the efficacies of 9-month treatments of the selected Panobinostat-Casodex combination and also a lower dose of Panobinostat. We expect that Casodex-Panobinostat combination treatment of castration-resistant patients will prevent biochemical and/or metastatic disease progression of these patients compared to historical controls in the same time period.

  • Baseline MUGA or ECHO must demonstrate LVEF ≥ the lower limit of the institutional normal.
  • ECOG Performance Status of ≤ 2
  • Documented history of adenocarcinoma of the prostate.
  • Patients must have evidence of disease progression while receiving androgen suppression therapy by orchiectomy or other primary hormonal therapy including, but not limited to (LHRH agonist therapy (e.g., leuprolide or goserelin) or LHRH antagonist (e.g. aberelix). Note: patients who have not undergone bilateral orchiectomy must continue LHRH therapy while on protocol
  • Testosterone must be < 50 ng/dl confirmed within 4 weeks prior to registration for patients on LHRH therapy
  • Patients must have evidence of disease progression with either one or both of the conditions listed:

    • Biochemical progression only
    • Metastases on bone scan
  • Patients may have received one chemotherapy, investigational agent or immunotherapy in the neoadjuvant, adjuvant setting or during initial LHRH therapy with new evidence of disease progression after discontinuation of therapy for ≥ 2 weeks.
  • Patients must have received one or more prior second line hormone therapy for progression while on LHRH treatment or orchiectomy.
  • Patients treated with one first line chemotherapy combination for hormone refractory progression ≥ 4 weeks prior to registration who have evidence of disease progression and had only one second line hormone therapy and did not experience PSA response to bicalutamide (Casodex®) withdrawal.

Exclusion Criteria:

  • Prior treatment with an HDAC inhibitor
  • Impaired cardiac function including any one of the following:

    • Screening ECG with a QTc > 450 msec confirmed by central laboratory prior to enrollment to the study

    • History of sustained ventricular tachycardia
    • Any history of ventricular fibrillation or torsades de pointes
