NCT00005839 was an early dose-finding study of oxaliplatin plus capecitabine for metastatic or recurrent solid tumors. The City of Hope/National Cancer Institute protocol was phase I, with dose-escalation cohorts designed to characterize toxicity and determine a tolerable combination dose. 12

The protocol projected 12–15 participants; that is not a verified actual enrollment or response denominator. Progression and survival were followed, but the main purpose was dose and safety characterization rather than a definitive comparison against standard treatment. The inspected historical record lists completion. 12

A verified maximum tolerated dose, dose-limiting-toxicity rate, and tumor-response estimate were not recovered from the inspected material. The study’s existence therefore does not establish that this combination improved survival in all of the different tumor types permitted by the protocol. 12
