Triple Negative Treatment Options
You are correct, there is no specific therapy for triple negative disease.
Some of the research that is ongoing involves some similarities with triple negatives and BrCA-1 (a genetic predisposition to breast cancer). There is an investigational agent called PARP-1 inhibitors currently being evaluated in BrCA and may present an option also for 3-negatives. Another finding is that there seems to be an overexpression of EGFR (epidermal growth factor receptor - a structure on the tumor that normally requires signals to promote growth, but in cancer may be perpetually in an active growth promotion configuration), and there are several drugs that may target this: gefitinib, erlotinib, cetuximab, panitumumab. Another target worth pursuing is the tumor blood vessels there are drugs with this mechanism being targeted. There are still other drugs like mTOR (mammalian target of rapamycin) inhibitors out there. Some of these are in the stages where activity is still being measured so any broad recommendations cannot be made (but hey, we're only brainstorming afterall).
On the practical side however, the best way to get additional treatment is in enrollment in a clinical trial. Discuss with your doctor if there is an ongoing trial in his/her insitution or if there are any nearby institutions where you can be enrolled. I don't know if it means anything to you, but your participation will help patients in the future in the same way that the research on patients who participated years ago have defined the treatment you already have received.
