About
This phase I clinical trial is studying the side effects and best dose of RO4929097 when given together with capecitabine in treating patients with refractory solid tumors. RO4929097 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving RO4929097 together with chemotherapy may kill more tumor cells.

OUTLINE: This is a multicenter, dose-escalation study of gamma-secretase inhibitor RO4929097.
Patients receive oral gamma-secretase inhibitor RO4929097 once daily on days 1-3, 8-10, and 15-17 and oral capecitabine twice daily on days 1-14. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
Patients may undergo tumor biopsy before and after treatment for biomarker analysis and blood sample collection periodically for pharmacokinetic and pharmacogenomic studies.
After completion of study treatment, patients are followed up for 30 days (Part 1) or every 3 months (Parts 2a and 2b).

Absolute neutrophil count >= 1,500/mcL
-
Platelets >= 100,000/mcL
-
Total bilirubin within normal institutional limits
-
AST (SGOT)/ALT (SGPT) =< 2.5 X institutional upper limit of normal
-
Creatinine within normal institutional limits OR creatinine clearance >= 60 mL/min/1.73 m^2 for patients with creatinine levels above institutional normal; a 24 hour urine collection and creatinine clearance can be measured if indicated
-
Treated, stable brain metastases are allowed; patients must be four weeks from radiation with stable brain imaging and off any medications used to treat brain metastases, excepting those anti-epileptics not metabolized by cytochrome P450
-
Women of childbearing potential and men must use two forms of contraception (i.e., barrier contraception and one other method of contraception) at least 4 weeks prior to study entry, 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 or her partner are participating in this study and for 12 months after study participation, the patient should inform the treating physician immediately
-
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 must confirm and document the patient's use of two contraceptive methods, dates of negative pregnancy test, and confirm the patient's understanding of the teratogenic potential of RO4929097
-
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 NOT to 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
-
Patients must demonstrate an ability to understand and the willingness to sign a written informed consent document
-
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; furthermore, 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
-
