Phase 1
Phase 2

Study Type: Interventional

Primary Outcome Measures:
  • Incidence of dose limiting toxicities [ Time Frame: 2 months ]

Secondary Outcome Measures:
  • To describe the pharmacokinetics of Torisel when administered with liposomal doxorubicin [ Time Frame: 2 weeks ]
  • Progression-free survival [ Time Frame: 2-4 months ]
  • Time to response [ Time Frame: 2-4 months ]
  • Clinical benefit rate [ Time Frame: 2-4 months ]
  • Overall survival [ Time Frame: 1 year ]
  • To assess the activity of the mTOR signaling pathway before and after therapy with Torisel and liposomal doxorubicin [ Time Frame: 2 months ]
  • To measure the proportion of cells with stem cell properties in tumors before and after treatment with Torisel and liposomal doxorubicin [ Time Frame: 2 months ]
  • objective response rate [ Time Frame: 2-4 months ]

Enrollment: 24
Study Start Date: September 2009
Study Completion Date: September 2012
Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Temsirolimus plus Liposomal Doxorubicin
Single arm: Temsirolimus is administered IV in cohorts of sequentially escalating cohorts at doses between 15 and 50 mg/M2 (body surface area), once weekly. Liposomal doxorubicin is administered IV at a dose of 30 mg per M2 (body surface area) once every 28 days. Treatment may continue with both drugs for 2 years. Treatment with Temsirolimus may continue beyond 2 years.
Drug: temsirolimus (Torisel) plus liposomal doxorubicin (Doxil)
Patients will be treated with temsirolimus weekly by iv and with liposomal doxorubicin (standard dose) by iv once every 28 days. Cohorts of patients receive sequentially increasing dose of temsirolimus until maximally tolerated dose (MTD) is reached. Once MTD (standard dose) is achieved, dosing will be with standard doses for each drug, but dosing will be modified based on toxicity.
Other Names:
  • Torisel
  • Doxil

Detailed Description:
The effectiveness of treatments for recurrent sarcomas is quite limited. One hypothesis to explain the refractory nature of recurrent sarcomas is the existence of chemotherapy-resistant sarcoma stem cells.
