Does anyone have experience with Memorial Sloan Kettering as an international patient? We are planning to go and participate in the bivalent vaccine trial following completion of our son Marko’s frontline therapy for stage 4 HR NB (COG protocol in the Royal Children’s Hospital in Melbourne, Australia). The estimated costs for the trial are naturally astronomical (we were told about $400,000 to be paid upfront), but were advised it is possible to negotiate them down significantly if we use a “broker”. We have no first hand contacts in the US so not sure how to start searching for a reliable one… to be honest not even sure what this would entail. Anyone able to offer advice? It will be highly appreciated!!!
