Ceritinib and Combination Chemotherapy in Treating Patients With Advanced Solid Tumors or Locally Advanced or Metastatic Pancreatic Cancer

PRIMARY OBJECTIVES:

I. Determine the maximum tolerated dose (MTD) and recommended Phase II dose (RP2D) of
ceritinib in combination with gemcitabine (gemcitabine hydrochloride) alone,
gemcitabine/nab-paclitaxel (paclitaxel albumin-stabilized nanoparticle formulation) and
gemcitabine/cisplatin in patients with advanced solid malignancies.

SECONDARY OBJECTIVES:

I. Characterize the safety profile of ceritinib in combination with gemcitabine based
chemotherapy in advanced solid malignancies.

II. Determine the pharmacokinetic profile of ceritinib, gemcitabine, nab-paclitaxel,
cisplatin and their metabolites when administered in combination in patients with advanced
solid tumors.

III. Determine the preliminary efficacy of the study combinations.

TERTIARY OBJECTIVES:

I. Explore potential biomarkers of efficacy to the study combination.

OUTLINE: This is a dose-escalation study of ceritinib. Patients are assigned to 1 of 3
treatment arms.

ARM 1 (ceritinib MTD then with gemcitabine alone):

Dose Escalation Cohort 1: Patients with advanced solid tumors for whom gemcitabine
hydrochloride-based therapy is clinically appropriate receive ceritinib orally (PO) once
daily (QD) on days 1-28 and gemcitabine hydrochloride intravenously (IV) over 30 minutes on
days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or
unacceptable toxicity.

Expansion Cohort 1E: Once the MTD of ceritinib has been determined, an additional 10 patients
with anaplastic lymphoma kinase positive (ALK-positive) advanced solid tumors who previously
progressed on gemcitabine hydrochloride-based therapy receive ceritinib and gemcitabine
hydrochloride as in the dose escalation cohort 1. Courses repeat every 28 days in the absence
of disease progression or unacceptable toxicity.

ARM 2 (ceritinib MTD then with gemcitabine and nab-paclitaxel):

Dose Escalation Cohort 2: Patients with advanced pancreatic cancer receive ceritinib PO QD on
days 1-28, gemcitabine hydrochloride IV over 30 minutes on days 1, 8, and 15, and paclitaxel
albumin-stabilized nanoparticle formulation IV over 30 minutes on days 1, 8, and 15. Courses
repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Expansion Cohort 2E: Once the MTD of ceritinib has been determined, patients with
ALK-positive advanced solid tumors receive ceritinib, gemcitabine hydrochloride, and
paclitaxel albumin-stabilized nanoparticle formulation as in the dose escalation cohort 2.
Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

ARM 3 (ceritinib MTD then with gemcitabine and cisplatin):

Dose Escalation Cohort 3: Patients with advanced solid tumors for whom gemcitabine
hydrochloride and cisplatin-based therapy is clinically appropriate receive ceritinib PO QD
on days 1-28, gemcitabine hydrochloride IV over 30 minutes on days 1 and 8, and cisplatin IV
on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable
toxicity.

Expansion Cohort 3E: Once the MTD of ceritinib has been determined, an additional 10 patients
with ALK-positive advanced solid tumors receive ceritinib, gemcitabine hydrochloride, and
cisplatin as in the dose escalation cohort 3. Courses repeat every 21 days in the absence of
disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for at least 4 weeks.
