Ribociclib In Combination with Belinostat in Patients with Metastatic Triple Negative Breast Cancer or Recurrent Platinum-Resistant Ovarian Cancer, Charge Study

Trial Status: Active

This phase I / Ib trial studies the best dose and effect of ribociclib and belinostat combination therapy in treating patients with triple negative breast cancer that has spread to other parts of the body (metastatic) or ovarian cancer that initially responded to treatment with platinum-containing drugs but then stoped responding (platinum-resistant) and has grown back (recurrent). Ribociclib and belinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving ribociclib and belinostat in combination may be effective in treating patients with advanced breast cancer and platinum-resistant recurrent ovarian cancer.

  • Active infection requiring systemic therapy
  • History of allergy or hypersensitivity to belinostat, ribociclib, or their binders
  • Uncontrolled arrhythmia, congestive heart failure or angina. Patients who have had a myocardial infarction, symptomatic pericarditis, or cardiac surgery should be at least 6 months from the event and free of active symptoms

  • Congenital long QT syndrome
  • Baseline corrected QT interval (QTcF) > 450 msec. The heart rate on the qualifying electrocardiogram (ECG) must be between 50 and 90 beats per minute (BPM)
  • Concurrent use of medication known to inhibit UGT1A1. Patients currently taking these medications must have discontinued >= 7 days prior to treatment day 1
  • Concurrent use of herbal supplements, unless approved by the principal investigator. Patients currently taking herbal supplements must have discontinued >= 7 days prior to treatment day 1
  • Concurrent use of medication with a known risk of inducing torsades de pointes (on the known risk list of crediblemeds.org) that cannot be discontinued or switched to a different medication >= 7 days prior to starting the study drug

Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception * Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy), total hysterectomy or tubal ligation at least 6 weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment * Male partner sterilization (at least 6 months prior to screening).

PRIMARY OBJECTIVE:

I. To assess the maximum tolerated dose (MTD) of ribociclib and belinostat in combination.

SECONDARY OBJECTIVES:

I. To assess the safety of ribociclib and belinostat in combination.

II. To assess the efficacy in the study population.

EXPLORATORY OBJECTIVES:

I. To develop a multi-gene expression-based biomarker and evaluate its predictive accuracy.

II. To explore how subclonal structure and phenotypic pathway activation varies in different sites of cancer.

III. To assess efficacy within subgroups defined by RB1 mutation.

OUTLINE: This is a dose-escalation study of ribociclib and belinostat.

Patients receive ribociclib orally (PO) once daily (QD) on days 1-28 or 8-28 and belinostat intravenously (IV) over 30 minutes on days 1-5. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days and then every 3 months for up to 2 years.
