Safety of ON 01910.Na and Irinotecan or ON 01910.Na and Oxaliplatin in Patients With Hepatoma

Summary

Studies done in the laboratory have demonstrated beneficial effects of ON 01910.Na, a new, unapproved drug, when it is used in combination either irinotecan and oxaliplatin, two approved, extensively used anti-cancer drugs. In these laboratory studies, mice implanted with cells (Bel-7402 cells) that came from a human tumor were used as a model of liver cancer. In mice that were not treated, the Bel-7402 cells formed very large tumors. In mice that were treated with ON 01910.Na, irinotecan or oxaliplatin alone, growth of tumors was reduced compared to the untreated group. When a combination of ON 01910.Na and irinotecan or of ON 01910.Na and oxaliplatin was used to treat the mice, tumor growth was completely inhibited. Another observation in these studies was that toxicity did not increase when the combinations were used. These results and similar results from other studies support the hypothesis that a combination of ON 01910.Na and irinotecan or of ON 01910.Na and oxaliplatin would be an effective and tolerable treatment for liver and other types of cancer. The primary objective of this phase 1 study is to find out what doses of ON 01910.Na in combination with either irinotecan or oxaliplatin are safe and tolerable in patients with liver and other types of cancer.
