Primary Outcome Measures :
  1. Four Cycle Progression-free Survival Rate [ Time Frame: 84 days (4 courses) ]

    Defined as the proportion of the study population that has not had tumor progression (symptomatic, RECIST progression, CA-125 progression) or died at the completion of the cycle four mark.

    RECIST criteria for progressive disease (PD) in target lesions: >= 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm. The appearance of one or more new lesions is also considered progression. In non-target lesions: Appearance of one or more new lesions and/or unequivocal progression of existing non-target lesions.

    CA-125 PD is based on the progressive serial elevation of serum CA-125 according to:

    A) elevated CA-125 pretreatment & normalization of CA-125 or C) CA-125 in normal range pretreatment: CA-125 >= 2x ULN on 2 occasions.

    B) elevated CA-125 pretreatment that never normalizes: CA-125 >= 2x nadir value on 2 occasions

Secondary Outcome Measures :
  1. Overall Response Rate [ Time Frame: Time from start of treatment to time of disease progression or death from any cause, whichever came first, assessed up to 2 years ]

    Response was assessed by Response Evaluation Criteria In Solid Tumors (RECIST 1.1).

    Evaluation of Target Lesions:

    Complete response (CR) - disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm.

    Partial response (PR) - at least 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.

    Evaluation of Non-Target Lesions:

    Complete response (CR) - disappearance of all non-target lesions and normalization of tumor marker level. All lymph nodes must be non-pathological in size (<10 mm short axis).

  2. CA125 Response Rate (GCIG Criteria) [ Time Frame: Time from start of treatment to time of disease progression or death from any cause, whichever came first, assessed up to 2 years ]

    The CA-125 response rate is defined as the proportion of patients with a Gynecological Cancer Intergroup (GCIG) CA-125 response.

    CA-125 response is defined as the moment CA-125 is reduced by 50% from the last pre-treatment level prior to start of therapy. The response must be confirmed and maintained with a consecutive CA-125 for at least 28 days.

  3. Overall Survival [ Time Frame: Up to 2 years ]
    Summary statistics, such as mean, median, counts and proportion, used to summarize the patients. Survival estimates computed using Kaplan-Meier method. Potential association between variables measured using Pearson correlation coefficients, chi-square tests, one- or two-sample t-tests or logistic regression analyses as appropriate. Non-parametric tests such as Spearman correlation coefficients, Fisher's exact tests and Wilcoxon rank sum tests may be substituted if necessary. Ninety-five percent confidence intervals will be constructed and selected results illustrated using figures and plots.

  4. Frequency and Severity of Adverse Events [ Time Frame: Up to 2 years ]
    Tabulated using counts and proportions detailing frequently occurring, serious and severe events of interest.

  5. Expression of Notch Biomarkers in Advanced Platinum Resistant Ovarian, Fallopian, and Primary Peritoneal Cancers. [ Time Frame: Up to 2 years ]
    An exploratory analysis for potential predictive biomarkers was performed on archival, paraffin-embedded tumor tissue for components of the Notch Pathway: Jagged-1 and NICD. The percentage of positive cells were scored into four categories: 0 (0%), 1 (1-33%), 2 (34-66%), and 3 (67-100%). The product of the intensity and percentage scores was used as the final score and classified as negative (0-4) or positive (5-9).

  6. Impact of RO49097 on Ascitic Fluid Circulating Tumor Cells [ Time Frame: Up to 2 years ]
    Impact of RO49097 on ascitic fluid circulating tumor cells.

  • All radiology studies must be performed =< 4 weeks prior to the start of therapy
  • No serious medical conditions such as myocardial infarction within 6 months prior to entry, congestive heart failure, unstable ventricular arrhythmia, uncontrolled hypertension, uncontrolled diabetes mellitus, uncontrolled psychotic disorders, serious infections, active peptic ulcer disease, psychiatric illness, or any other medical conditions that might be aggravated by treatment or limit compliance
  • Currently no active, second malignancy other than non-melanoma skin cancers

    • NOTE: Patients are not considered to have a "current active" malignancy if they have completed anti-cancer therapy and are considered by their physician to be at less than 30% risk of relapse
  • Absence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial
  • The effects of RO4929097on the developing human fetus at the recommended therapeutic dose are unknown; for this reason and because Notch signal pathway inhibitors are known to cause interruption of the embryonic signaling pathway and may lead to serious or life-threatening birth defects, including brain deformities, facial malformation, heart problems, or abnormal organs; if women of childbearing potential do not abstain* from sexual activity they must use two forms of contraception (i.e., barrier contraception and one other method of contraception) at least 4 weeks prior to study entry; women of childbearing potential can either be abstinent or use two forms of contraception for the duration of study participation and for at least 12 months post-treatment; should a woman become pregnant or suspect she is pregnant while she is participating in this study and for 12 months after study participation, the patient should inform the treating physician immediately

    • Abstinent from sexual activity at least 4 weeks prior to study entry
    • Pregnancy Testing: Women of childbearing potential are required to have a negative serum pregnancy test (with a sensitivity of at least 25 mIU/mL) within 10-14 days and within 24 hours prior to the first dose of RO4929097 (serum or urine); a pregnancy test (serum or urine) will be administered every 4 weeks if their menstrual cycles are regular or every 2 weeks if their cycles are irregular while on study within the 24-hour period prior to the administration of RO4929097; a positive urine test must be confirmed by a serum pregnancy test; prior to dispensing RO4929097, the investigator or clinical staff must confirm and document the patient's use of two contraceptive methods or abstinence, dates of negative pregnancy test, and confirm the patient's understanding of the potential of RO4929097 to cause serious or life-threatening birth defects
    • Female patients of childbearing potential are defined as follows:

      • Patients with regular menses
      • Patients, after menarche with amenorrhea, irregular cycles, or using a contraceptive method that precludes withdrawal bleeding
      • Women who have had tubal ligation
    • Female patients may be considered to NOT be of childbearing potential for the following reasons:

      • The patient has undergone total abdominal hysterectomy with bilateral salpingo-oophorectomy or bilateral oophorectomy
      • The patient is medically confirmed to be menopausal (no menstrual period) for 24 consecutive months
      • Pre-pubertal females; the parent or guardian of young female patients who have not yet started menstruation should verify that menstruation has not begun; if a young female patient reaches menarche during the study, then she is to be considered as a woman of childbearing potential from that time forward
  • Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

  • Patients may not be receiving any other investigational agents
  • Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to RO4929097 or other agents used in the study
  • Patients taking medications with narrow therapeutic indices that are metabolized by cytochrome P450 (CYP450), including warfarin sodium (Coumadin ®) are ineligible
  • Preclinical studies indicate that RO4929097 is a substrate of CYP3A4 and inducer of CYP3A4 enzyme activity; caution should be exercised when dosing RO4929097 concurrently with CYP3A4 substrates, inducers, and/or inhibitors; patients who are taking concurrent medications that are strong inducers, inhibitors or substrates of CYP3A4 should be switched to alternative medications to minimize any potential risk; if such patients cannot be switched to alternative medications, they will be ineligible to participate in this study
  • Patients with malabsorption syndrome, bowel obstruction, or other condition that would interfere with intestinal absorption; patients must be able to swallow tablets
  • Patients who are serologically positive for Hepatitis A, B or C, or have a history of liver disease, other forms of hepatitis or cirrhosis are ineligible
  • Patients with uncontrolled hypocalcemia, hypomagnesemia, hyponatremia, hypophosphatemia or hypokalemia defined as less than the lower limit of normal for the institution, despite adequate electrolyte supplementation are excluded from this study
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia other than chronic, stable atrial fibrillation, or psychiatric illness/social situations that would limit compliance with study requirements
  • Pregnant women are excluded from this study because RO4929097 is a Notch pathway inhibiting agent with the potential for serious or life-threatening birth defects or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with RO4929097, breastfeeding should be discontinued if the mother is treated with RO4929097; these potential risks may also apply to other agents used in this study
  • Known HIV-positive patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with RO4929097; in addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy; appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated
  • Cardiovascular (within 7 days prior to start of study treatment): baseline QTc > 470 msec (female), QTc > 450 msec (male)

    • History of risk factors for QT interval prolongation, including, but not limited to family or personal history of long QT syndrome, recurrent syncope without known etiology or sudden unexpected death
    • History of torsade de pointes or other significant cardiac arrhythmias or the need for concomitant meds with known potential to prolong QT interval or antiarrhythmics
