Intervention Details:
  • Drug: LBH589

    LBH589 will be administered orally at a dose of 30mg (1 - 20mg capsule and 2 - 5g capsules) on Monday, Wednesday and Friday of each week (three times a week). Patients may continue treatment with oral LBH589 until they experience unacceptable toxicity that precludes further treatment, disease progression, and/or at the discretion of the investigator.

    The LBH589 capsules should be swallowed by mouth with a glass of water in the morning. The recommended way to take LBH589 is after not eating for at least 2 hours. You should also not eat for another 2 hours after taking your LBH589 capsules. The daily dose of LBH589 should be taken at approximately the same time each day. You should avoid eating grapefruit, seville oranges, or drinking grapefruit or seville orange juice during the study.

Primary Outcome Measures :
  1. To evaluate the effect of LBH589 on overall survival (OS) in patients with colorectal cancer [ Time Frame: 18 months ]

Secondary Outcome Measures :
  1. Time to tumor progression and response rates [ Time Frame: 18 months ]

  • Life expectancy must be greater than 12 weeks

Exclusion Criteria:

  • Prior HDAC, DAC, HSP90 inhibitors or valproic acid for the treatment of cancer
  • Patients who will need valproic acid for any medical condition during the study or within 5 days prior to first LBH589 treatment
  • 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
    • Patients with congenital long QT syndrome
    • History of sustained ventricular tachycardia
    • Any history of ventricular fibrillation or torsades de pointes
