Brief Summary:
This phase II trial is studying how well giving vorinostat together with bortezomib works in treating patients with advanced soft tissue sarcoma. Vorinostat and bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving vorinostat together with bortezomib may kill more tumor cells.

Condition or disease Intervention/treatment Phase
Recurrent Adult Soft Tissue Sarcoma Stage III Adult Soft Tissue Sarcoma Stage IV Adult Soft Tissue Sarcoma Drug: vorinostat Drug: bortezomib Phase 2

Detailed Description:


I. To determine the objective response rate in patients with advanced soft tissue sarcoma treated with vorinostat and bortezomib.


I. Characterize the toxicity of this regimen in these patients. II. Evaluate the progression-free survival and median overall survival of patients treated with this regimen.


Patients receive vorinostat orally (PO) once daily on days 1-14. Patients also receive bortezomib intravenously (IV) over 3-5 seconds on days 1, 4, 8, and 11. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study therapy, patients are followed up every 6 months for up to 2 years. (As of Addendum 7, patient follow-up no longer required.)

Arm Intervention/treatment
Experimental: Treatment (vorinostat, bortezomib)
Patients receive 400 mg vorinostat orally once daily on days 1-14. Patients also receive 1.3 mg/m^2 bortezomib IV over 3-5 seconds on days 1, 4, 8, and 11. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
Drug: vorinostat
400 mg given PO
Other Names:
  • L-001079038
  • SAHA
  • suberoylanilide hydroxamic acid
  • Zolinza

Drug: bortezomib
1.3 mg/m^2 given IV
Other Names:
  • LDP 341
  • MLN341

Primary Outcome Measures :
  1. Confirmed Tumor Responses [ Time Frame: Up to 2 years ]

    The number of confirmed tumor responses is defined as a complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) on two consecutive evaluations at least six weeks apart.

    Complete Response (CR): Disappearance of all target lesions. Partial Response (PR): At least a 30% decrease in the sum of the longest dimension (LD) of target lesions taking as reference the baseline sum LD.

Secondary Outcome Measures :
  1. Progression Free Survival [ Time Frame: Up to 2 years ]
    Progression-free survival is defined as the time from registration to the time of progression or death, whichever comes first. The distribution and median of progression-free survival times will be estimated using the method of Kaplan-Meier.

  2. Overall Survival [ Time Frame: Time from registration to death due to any cause, assessed up to 2 years ]
    The distribution of survival time will be estimated using the method of Kaplan-Meier.
