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.

Primary Outcome Measures:
  • Maximum-tolerated dose of gamma-secretase inhibitor RO4929097, defined as the dose level where no more than 1 out of 6 patients experience DLT at the highest dose level below the MAD, graded according to NCI-CTCAE version 4.0 (Phase Ib) [ Time Frame: Up to 28 days ] [ Designated as safety issue: Yes ]
  • Progression-free survival as defined by RECIST 1.1 (Phase II) [ Time Frame: Time from randomization to either the first evidence of disease progression or death from any cause, assessed up to 4 months ] [ Designated as safety issue: No ]
    Stratified log rank test will be used to compare PFS between the two arms.

Secondary Outcome Measures:
  • Change in protein levels from pre- and post-treatment biopsies (Phase Ib and II) [ Time Frame: Baseline to up to 4 months ] [ Designated as safety issue: No ]
    Pre- and post-treatment levels will be compared using the paired t test, for the following three comparisons: post-GDC vs pre-treatment, post-RO4929097 vs. pre-treatment, and post-combo vs pre-treatment.

  • Overall survival (Phase II) [ Time Frame: Up to 4 months ] [ Designated as safety issue: No ]
    The overall survival probabilities will be estimated using the Kaplan-Meier curve.

  • Response rate (CR + PR) as assessed by RECIST 1.1 (Phase Ib and II) [ Time Frame: Up to 4 months ] [ Designated as safety issue: No ]
    Response rate will be estimated with the confidence interval provided.

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.

OUTLINE: This is a phase I, dose-escalation study of gamma-secretase/notch signalling pathway inhibitor RO4929097 followed by a phase II study.


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.
