Preliminary Efficacy and Safety of INNO-206 Compared to Doxorubicin in Advanced Soft Tissue Sarcoma

Study Overview
=================
Brief Summary
-----------------
This is a phase 2b, randomized, open-label, prospective, multicenter study comparing treatment with INNO 206 to doxorubicin in subjects with metastatic, locally advanced, or unresectable soft tissue sarcomas who have not been previously treated with any chemotherapy except potentially as adjuvant or neoadjuvant chemotherapy, and no evidence of tumor recurrence has occurred for at least 12 months.

Detailed Description
-----------------
One hundred five subjects will be enrolled and randomized 2:1 to receive either INNO-206 or doxorubicin. INNO-206 at a dosage of 350 mg/m2 (doxorubicin equivalents of 260 mg/m2) will be administered as a 30 minute IVI on Day 1 of each cycle to approximately 70 subjects. Doxorubicin (75 mg/m2) will be administered to approximately 35 subjects on Day 1 of each cycle. An individual cycle of therapy will be defined as a 3-week (21-day) period. Cycles will be repeated every 3 weeks. Multiple cycles may be administered until the subject is withdrawn from therapy or until a maximum of 6 cycles are administered. Overall response rates as well as individual categories of response (CR, PR, SD, and PD) will be determined using RECIST 1.1.[28] Time-to-event endpoints, including PFS and OS will be assessed using the Kaplan Meier method.[30] Evaluation of 4- and 6-month progression-free survival will also be performed. Toxicity (adverse events) will be recorded using the NCI CTCAE, version 4.0 (published 28 May 2009).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Progression-free survival | Progression-free survival (PFS) is defined as the time from enrollment to first documentation of objective tumor progression or to death due to any cause in the absence of previous documentation of objective tumor progression. | Over the duration of the trial, approximately 24 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall Survival | Survival is defined as the time from enrollment to date of death. In the absence of confirmation of death, survival time will be censored at the last date the subject is known to be alive. | Approximately 36 months. | 
| Progression-free survival at 4 and 6 months |  | Month 4 and 6 | 
| Objective overall response rate (ORR) | The overall tumor response rate is defined as the total proportion of subjects who have an objective tumor response (CR + PR). | Approximately 24 months. | 
| Safety measures. | Adverse events, Ability to remain on assigned treatment (tolerability), Clinical and laboratory data including physical examinations, vital signs, weight, MUGA/cardiac ultrasound evaluations, ECG results and laboratory test results, Use of concomitant medications | Approximately 24 months. |
