NCT ID: NCT01703754

Last Updated: 2025-08-28

Basic Information

• Recruitment Status: TERMINATED
• Clinical Phase: PHASE2
• Total Enrollment: 12 participants

• Study Completion Date: 2014-08-07

Brief Summary

Phase II, randomized, safety and efficacy study in recurrent/metastatic breast cancer with accessible lesions.

Primary End point is rate of Progression Free Survival (PFS) at the 16 week treatment time point. Hypothesis: Adenoviral vector (Ad-RTS-hIL-12) alone and in combination with chemotherapy (palifosfamide) is safe and efficacious.

Detailed Description

Multicenter, open-label, randomized study evaluating the safety and efficacy of INXN-1001 (veledimex) and INXN-2001 (Ad-RTS-hIL-12) alone and in combination with palifosfamide.

Part 1 is the safety run-in where a safety assessment will be made after 1 cycle of therapy.

Part 2, eligible subjects will be randomly assigned to active treatment Arms A or C.

Once the monotherapy (Arm A) is determined to be safe and tolerable, Part 1 combination therapy (Arm C) will begin.

Subjects should receive six cycles of study treatment, in the absence of meeting withdrawal criteria.
