A Phase I Trial of ABT-263 (Navitoclax), a Bcl-2 Inhibitor, and Sorafenib (Nexavar) in Patients With Relapsed or Refractory Solid Organ Tumors

This phase I trial studies the side effects and the best dose of navitoclax when given
together with sorafenib tosylate in treating patients with solid tumors that have returned
(relapsed) or do not respond to treatment (refractory). Navitoclax and sorafenib tosylate may
stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) of the combination of navitoclax and
sorafenib tosylate (sorafenib) in patients with advanced solid tumors. (Dose escalation
cohort) II. To better characterize the toxicity profile of the combination of navitoclax and
sorafenib. (Dose expansion cohort)

SECONDARY OBJECTIVES:

I. To identify any activity of this treatment combination in patients with metastatic cancer.
(Dose escalation cohort) II. To seek preliminary evidence of activity of this treatment
combination in patients with hepatoma. (Dose expansion cohort)

TERTIARY OBJECTIVES:

I. To determine whether the combination of navitoclax and sorafenib induces apoptosis that
can be detected by peripheral blood biomarker analysis. (Dose escalation cohort) II. To
assess peripheral blood biomarkers and pharmacokinetics in a more homogenous population.
(Dose expansion cohort) III. To determine whether treatment is associated with Mcl-1 down
regulation in hepatocellular carcinoma (HCC) at the maximum tolerated dose (MTD). (Dose
expansion cohort) IV. To assess in a preliminary fashion whether pretreatment tumor cell
levels of Mcl-1 predict response to this regimen through serial biopsies. (Dose expansion
cohort)

OUTLINE: This is a dose-escalation study of navitoclax.

Patients receive navitoclax orally (PO) once daily (QD) on days 1-21 (days 1-28 course of 1
only) and sorafenib tosylate PO twice daily (BID) on days 1-21. Courses repeat every 21 days
in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months.

- International normalized ratio (INR) =< 1.4

- Platelets >= 100,000/mm^3

- Total bilirubin =< 1.5 x ULN (institutional upper limit of normal) (patients with
Gilbert's syndrome may have direct bilirubin > 2.5 x ULN)

[SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT])
=< 2.5 x institutional ULN

- Serum creatinine =< 1.5 times the ULN

- Able to swallow and retain oral medication

- Negative serum pregnancy test =< 7 days prior to registration for women of
childbearing potential

- NOTE: women will be considered not of childbearing potential if they are
surgically sterile (bilateral oophorectomy or hysterectomy) and/or
post-menopausal (amenorrheic for at least 12 months)

- Ability to understand and the willingness to sign a written informed consent document

- Willing to provide tissue samples for correlative research purposes

Exclusion Criteria:

- Unresolved toxicity of National Cancer Institute Common Terminology Criteria for
Adverse Events, version 4.0 (NCI CTCAE v 4.0) grade 2 or higher from previous
anti-cancer therapy, except alopecia

- Receiving any other investigational agents =< 28 days prior to registration
