A Phase 1 Dose-Escalation Study of the Safety and Clinical Effects of ON 01910.Na in Combination With Either Irinotecan or Oxaliplatin in Patients With Hepatoma and Other Advanced Solid Tumors
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.

This is an open-label, 2-arm, dose-escalation combination-therapy study in which patients
with hepatoma and other advanced malignancies will be assigned by the Investigator to dosing
with either irinotecan plus ON 01910.Na (Group A), or oxaliplatin plus ON 01910.Na (Group
B). Note: As of Amendment 2 of this protocol, treatment in the irinotecan arm of the study
(Group A) is closed to enrollment and patients will be enrolled only in Group B, the
oxaliplatin treatment arm. Patients will be enrolled in 1 of 4 Cohorts (4 sequential Cohorts
in Group B) of 3 patients each. Up to 6 additional patients will be tested at the MTD.

Inclusion Criteria:
- Male and female patients ≥18 years of age with histologically or cytologically
confirmed hepatoma and other solid tumors that are metastatic or progressive, for
whom no standard therapy holds curative potential and for whom irinotecan or
oxaliplatin are reasonable treatment options.
- Patients must have evaluable disease, either measurable on imaging or with
informative tumor marker(s).
- Eastern Collaborative Oncology Group (ECOG) Performance Status of ≤2.
- Life expectancy >12 weeks.
- Any acute or chronic adverse effects of prior chemotherapy have resolved to
- Existing or planned central venous access with a 2-channel infusion catheter system.
- Laboratory values meet the following criteria: Absolute neutrophil count ≥1,500
cells/µL; Platelets ≥100,000 cells/µL; Total bilirubin ≤1.5 times the upper limit of
normal; AST (SGOT) ≤2.5 times the upper limit of normal; ALT (SGPT) ≤2.5 times the
upper limit of normal; Serum creatinine ≤1.5 mg/dL or a measured creatinine clearance
≥50 mL/min; Negative βhCG test in women of childbearing potential (defined as women
≤50 years of age or history of amenorrhea for ≤12 months prior to study entry).
- Patients with primary liver cancer or hepatic metastasis are eligible to enroll,
provided they meet the following: Total bilirubin is ≤2 mg/dL; AST and ALT are each
≤5 times the institutional upper limit of normal; Ascites, if present, is manageable
with diuretic agents alone.
- If there is a history of treated brain metastases, these must have been clinically
stable for ≥4 weeks prior to enrollment.
Exclusion Criteria:
- Women who are pregnant or lactating.
- Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for
nitrosoureas or mitomycin C) prior to entering the study.
- Severe liver dysfunction (Child-Pugh Class C or uncompensated Class B with persistent
encephalopathy, persistent ascites, or prothrombin time >1.5 times the upper limit of
normal) is present.
- Patients with a history of esophageal bleeding are excluded unless arices have been
sclerosed or banded and bleeding episodes have not occurred during the prior 6
months.
- Contraindications, including known hypersensitivity, to the assigned chemotherapy
agent (i.e., irinotecan or oxaliplatin).
- Prior receipt of ON 01910.Na or prior participation in this protocol.
- Use of any investigational agents within 4 weeks of study enrollment.
- Uncontrolled intercurrent illness including, but not limited to ongoing or active
infection or psychiatric illness/social situations that would limit compliance with
study requirements, as determined by the Investigator.
- Patients with ascites requiring active medical management including paracentesis,
peripheral bilateral edema or hyponatremia (defined as serum sodium value of <134
Meq/L).
