Vismodegib and Gamma-Secretase/Notch Signalling Pathway Inhibitor RO4929097 in Treating Patients With Advanced or Metastatic Sarcoma

• Status: Completed
• Trial end date: 2015-02-01
• Target enrollment: 0
• Participant gender: All

Summary

This randomized phase I/II clinical trial is studying the side effects and best dose of gamma-secretase/notch signalling pathway inhibitor RO4929097 when given together with vismodegib and to see how well they work in treating patients with advanced or metastatic sarcoma. Vismodegib may slow the growth of tumor cells. Gamma-secretase/notch signalling pathway inhibitor RO4929097 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving vismodegib together with gamma-secretase/notch signalling pathway inhibitor RO4929097 may be an effective treatment for sarcoma.

• Absolute neutrophil count >= 1,500/mcL

• Hemoglobin >= 9 g/dl

• Platelets >= 100,000/mcL

• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 3 X upper limit of normal

• Creatinine =< 1.5 or creatinine clearance >= 60 mL/min/1.73 m^2 for patients with creatinine levels above 1.5

• Patients treated at Memorial Sloan-Kettering Cancer Center may consent to optional tumor biopsies before and after initiation of study drug; tumor biopsies should be obtained after fulfilling requirements

• Women of child-bearing 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 participating in this study, she should inform her treating physician immediately; women of childbearing potential are required to have a negative pregnancy test (with a sensitivity of at least 25 mIU/mL) within 7 days and within 24 hours prior to the first dose of GDC-0449 and/or RO4929097 (serum or urine); a pregnancy test (serum or urine) will be administered every 3 weeks to all women of childbearing potential, at the start of each drug cycle; a positive urine test must be confirmed by a serum pregnancy test; prior to dispensing GDC-0449 and/or RO4929097, the investigator must confirm and document the patient's use of two contraceptive methods, dates of negative pregnancy test, and confirm that patient understands the teratogenic potential of GDC-0449 and/or 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 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.

• The patient is post-menopausal defined by amenorrhea for at least 1 year in a woman > 45 years old

• Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

• Patients may not receive other investigational agents within 2 weeks of enrollment in this study; patients treated with bevacizumab should be off therapy for 4 weeks; other experimental or immuno therapies should wait for 4 half-lives or 4 weeks, whichever is longer; prior exposure to Notch or Hedgehog inhibitors is not allowed; patients who have not recovered to less than CTCAE grade 2 from prior therapies are ineligible

• History of allergic reactions attributed to compounds of similar chemical or biologic composition to GDC-0449 or RO4929097 used in the study

• Patients taking medications with narrow therapeutic indices that are metabolized by cytochrome P450 (CYP450), including warfarin sodium (Coumadin®) are ineligible; patients on warfarin may be considered for enrollment after cessation of warfarin and appropriate transition to alternate anti-coagulation agents

• Preclinical studies indicate that RO4929097 is a substrate of cytochrome P450, family 3, subfamily A, polypeptide 4 (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; the following medications with strong potential for interaction are not allowed: indinavir, nelfinavir, ritonavir, clarithromycin, itraconazole, ketoconazole, nefazodone

• Caution should be exercised when dosing GDC-0449 concurrently with medications that are substrates of cytochrome P450 family 2, subfamily C, polypeptide 8 (CYP2C8), CYP2C9, and CYP2C19 and have narrow therapeutic windows; caution should be exercised when dosing GDC-0449 concurrently with inhibitors of CYP3A4

• Patients must be able to swallow pills; patients with malabsorption syndrome or other condition that would interfere with intestinal absorption

• Patients with clinically active liver disease, including active viral or other hepatitis or cirrhosis, are ineligible

• Patients with uncontrolled electrolyte abnormalities including hypophosphatemia, hypocalcemia, hypomagnesemia, hyponatremia or hypokalemia or 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, a history of torsades de pointes or other significant cardiac arrhythmias that require antiarrhythmics or other medications known to prolong corrected QT interval (QTc); psychiatric illness/social situations that would limit compliance with study requirements
