This phase I/II study is designed to compare different treatment schedules of a personalized anti-cancer vaccine protocol which combines the cryoablation of a selected metastatic lesion with intra-tumor immunotherapy. The cryoablation causes the tumor to release tumor-specific antigens into the surrounding environment. The injection of bioengineered allogeneic immune cells, AlloStim(TM), into the lesion is designed to modulate the immune response and educate the immune system to kill other tumor cells.
The study will assess three different dosing schedules. A standard 3 plus 3 study design will be used. The starting dose for each dosing schedule will be escalated in subsequent groups of patients. The study will evaluate safety of increased frequency of AlloStim (TM) dosing and anti-tumor effect of the new proposed dose and frequency schedule.

NONE
AlloStim is derived from the blood of normal blood donors and is intentionally mismatched to the recipient.
Percutaneous ablation of a single metastatic tumor lesion usually in liver or bone. The procedure is conducted under CT or ultrasound image-guidance.

To determine the safety of increased frequency of dosing
Three patients are enrolled at each frequency schedule in the absence of dose limiting toxicity (DLT). A DLT is defined as any allergic or autoimmune toxicity or other study drug related toxicity Grade 3 or higher during the DLT assessment window.
Time frame: Window is defined as the time required receiving two doses of AlloStim IV push plus 28 days follow-up
Health-Related Quality of Life
Health-Related Quality of life will be measured using the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30) and its supplementary breast cancer questionnaire (QLQ-BR23).
Time frame: From enrollment to 90 days after last dose administration.
Evaluate the anti-tumor effect of Allostim combined with cryoablation at the new proposed dose and frequency schedule.
Each treatment schedule will be monitored for radiological, pathological, and immunological response. These assessments will be compared between three treatment schedules.
Time frame: 90 days after last dose administration
