Trial Information

A Phase I Study of Sorafenib in Combination With the Histone Deacetylase Inhibitor, Entinostat in Patients With Advanced Cancers


PRIMARY OBJECTIVES:

I. To determine the maximum-tolerated dose of entinostat in combination with sorafenib
tosylate in patients with advanced, inoperable, or metastatic solid tumors.

II. To determine the safety and tolerability of this regimen in these patients.

SECONDARY OBJECTIVES:

I. To determine the pharmacokinetic profile of this regimen in patients with
refractory/relapsed acute myeloid leukemia (AML).

II. To assess the preliminary anti-tumor activity of this regimen in patients with advanced,
inoperable, or metastatic solid tumors or refractory/relapsed AML.

III. To evaluate histone deacetylase (HDAC) inhibition of histone acetylation in leukemia
blast cells.

TERTIARY OBJECTIVES (EXPLORATORY):

I. To evaluate the expression of downstream markers of drug activity such as p38, MCL-1,
FLT-3, and VEGFR-2 in leukemia blast cells.

II. To evaluate SNDX-induced expression of p21^WAF1/CIP1 in leukemia blast cells.

OUTLINE: This is a multicenter, dose-escalation study of entinostat.

Patients receive oral entinostat once daily on days 1 and 15 and oral sorafenib tosylate
twice daily on days 1-28 (days 15-28 only of course 1). Courses repeat every 28 days in the
absence of disease progression or unacceptable toxicity.

Patients in the expansion cohort undergo blood, bone marrow aspiration, or biopsy for
pharmacokinetic studies and biomarker analysis.

After completion of study therapy, patients are followed up for up to 24 months.


Inclusion Criteria:

- Histologically or cytologically confirmed solid tumors (dose-escalation only)

including stem cell transplantation, is expected to result in meaningful
clinical response (expansion cohort only)

applicable

- QTc > 490 msec

- ST-T wave changes consistent with acute MI or acute ischemia

- No clinically active serious infections defined as ≥ grade 2

- No substance abuse, medical, psychological, or social conditions that may, in the
opinion of the Investigator, interfere with the patient's participation or evaluation
of the study results

- No condition that is unstable or that could jeopardize the safety of the patient and
his/her study compliance

- No known HIV infection

- No significant gastrointestinal disorder that, in the opinion of the Investigator,
could interfere with the absorption of entinostat and/or sorafenib tosylate including
any of the following:

- Significant, uncontrolled inflammatory bowel disease

- Abdominal fistula or gastrointestinal perforation within the past 6 months

- Extensive small bowel resection

- Requiring tube feeding or parenteral hydration and/or nutrition

- No concurrent immunosuppressive therapies, including high-dose systemic
corticosteroids (> 0.5 mg/kg/day prednisone or equivalent) unless used intermittently
or as a tapered course for ≤ 4 weeks

- Concurrent hydroxyurea and/or anagrelide allowed

- Concurrent warfarin allowed provided the dose has been stable for the past 2 months
and INR has been between 2 and 3

- More than 4 weeks since prior chemotherapy, immunotherapy, or investigational agents
(=< 2 weeks for leukemia patients in expansion cohort)

- More than 2 weeks since prior palliative radiotherapy

- More than 4 weeks since major surgery

- More than 2 weeks since minor surgery (e.g., talc pleurodesis, excisional biopsy,
etc.)

- Concurrent hormonal therapies (e.g., LHRH antagonists, megestrol, octreotide,
calcitonin, etc.) allowed

during course 1)

- No other concurrent investigational agents
