ARQ-761 Treatment With Gemcitabine/Nab-Paclitaxel Chemotherapy In Pancreatic Cancer

Screening:

- Demographic information (age, gender, race, ethnic origin).

- Physical exam and review of your past and present medical history including any
surgeries a and/or infections;

- Vital signs (temperature, pulse, respirations, blood pressure); height, weight;

- Concurrent medications (medications whether prescribed or over-the counter that you have
taken or are currently taking);

- Performance Status (how well you are able to perform daily activities)

- Review of any side effects that you may have experienced or may be experiencing before
receiving the study drug and medications

- Blood will be collected for routine lab tests

- Urinalysis

- Pregnancy Test (if you are a woman of child-bearing potential)

- Radiologic evaluation (review of any CT scans you may have had)

- Tumor measurements:

- A CT scan (chest/abdomen/pelvis) is a special test that produces an image of your body
using a. small amount of radiation. The image shows the body tissues and structures in
three dimensions (3-D).

- Electrocardiogram (EKG), a tracing of the electrical activity of the heart;

- Oxygen saturation (measures how much oxygen the blood is carrying)

- Biopsy for correlative studies - if archived tumor specimen cannot be obtained, you will
need to undergo a fresh biopsy

- Completion of a Quality of life questionnaire

This visit may last approximately 1-2 hours. Visits that included radiologic evaluation may
last longer, approximately 2-3 hours.

The treatment consists of:

- A 2 week lead-in monotherapy of ARQ-761 - they will receive the current dose of ARQ761
alone

o The amount of ARQ-761 that will be given to you will depend on the time at which you
are enrolled in the study.

- Afterwards the 28-day cycle of combination treatment of ARQ-761 along with gemcitabine
(1000 mg/m2) + nab-paclitaxel (125 mg/m2) will begin

Lead-in 2 weeks before the combination therapy begins:
