About
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.
Full description
PRIMARY OBJECTIVES:
I. To determine the maximum-tolerated dose (MTD) of gamma-secretase inhibitor RO4929097 (RO4929097) when given in combination with fixed-dose Hedgehog antagonist GDC-0449 (GDC-0449) which will become the recommended dose for the phase II portion of this study. (Phase Ib) II. To assess the progression-free survival (PFS) of the combination of RO4929097 with and without GDC-0449 in two arms of patients with advanced sarcoma. (Phase II)
SECONDARY OBJECTIVES:
I. To describe the tolerability and adverse event profile of daily GDC-0449 administered orally in combination with daily RO4929097 administered orally for 21 consecutive days. (Phase Ib) II. To describe the pharmacokinetics of the combination of the combination of GDC-0449 and RO4929097. (Phase Ib) III. To assess Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 overall response rates (complete and partial response [CR+PR]) for combination therapy. (Phase Ib and II) IV. To conduct pharmacodynamic studies in tissue biopsies (pre- and post-study) for explorative and hypothesis-generating studies. (Phase Ib and II) V. To assess overall survival. (Phase II) VI. To further describe the pharmacokinetics and pharmacodynamics of the combination of GDC-0449 and RO4929097 at the phase II dose at the continuous schedule. (Phase II) V. To conduct pharmacodynamic studies in tissue biopsies (pre- and post- study drug[s]) for explorative and hypothesis generating studies. (Phase II)
OUTLINE: This is a phase I, dose-escalation study of gamma-secretase/notch signalling pathway inhibitor RO4929097 followed by a phase II study.
PHASE IB:
PART A: Patients receive vismodegib orally (PO) once daily (QD) on days 1-21.
PART B: Beginning within 7 days of finishing part A, patients receive vismodegib PO and gamma-secretase/notch signalling pathway inhibitor RO4929097 PO QD on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
PHASE II: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive gamma-secretase/notch signalling pathway inhibitor RO4929097 PO QD on days 1-21.
ARM II: Patients receive vismodegib PO and gamma-secretase/notch signalling pathway inhibitor RO4929097 PO QD on days 1-21.
In both arms, courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 4 weeks.

Inclusion criteria
Patients must have histologically or cytologically confirmed sarcoma
All Patients must have measurable disease as defined by RECIST 1.1

There is a minimum of 1 prior therapy; however, there are no minimum systemic therapy requirements for well differentiated or de-differentiated liposarcoma, clear cell sarcoma, chondrosarcoma, alveolar soft part sarcoma and chordomas which have no effective therapies; for Phase Ib, there are no maximum limits to number of prior therapies; for Phase II, there is a maximum of 5 prior chemotherapy regimens including tyrosine kinase inhibitors (TKI); the last dose of systemic therapy (including TKI) must have been given at least 2 weeks prior to initiation of therapy; patients receiving nitrosourea (such as BCNU) or mitomycin C must have received their last dose of such therapy at least 6 weeks prior to initiation of therapy; patients receiving bevacizumab must wait at least 4 weeks; patients receiving experimental immunotherapy or antibody based therapies must wait a minimum of 4 weeks or 4 half-lives, whichever is longer; this should be discussed with the principal investigator before registration; tumor biopsies should be performed only after meeting these requirements; patients should recover to less than Common Terminology Criteria for Adverse Events (CTCAE) grade 2 toxicities related to previous therapies to be eligible
Patients with metastatic or locally advanced (inoperable) gastrointestinal stromal tumor (GIST) must have progressed on imatinib and sunitinib or be intolerant to both drugs; the last dose of tyrosine kinase inhibitors imatinib or sunitinib should be given at least 2 weeks prior to initiation of therapy
Patients with brain metastasis that have been treated with definitive surgery or radiation and have been clinically stable for 3 months following the procedure with no neurological signs or symptoms and no requirement for systemic glucocorticoids are eligible for study
Patients must not have current evidence of another malignancy except non-melanoma skin cancer and superficial bladder cancer
Leukocytes >= 3,000/mcL
Absolute neutrophil count >= 1,500/mcL
Hemoglobin >= 9 g/dl
Platelets >= 100,000/mcL
Total bilirubin =< upper limit of normal
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
