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

Study Overview
=================
Brief Summary
-----------------
This is a study of ARQ-761 (beta-lapachone) with gemcitabine/nab-paclitaxel chemotherapy in subjects with advanced (metastatic, unresectable, or recurrent) pancreatic cancer that has not been treated with gemcitabine.

Detailed Description
-----------------
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: Monotherapy of ARQ-761 Day 1: Vital signs Review of medical history Physical exam Review of any medications they are taking or have taken Review of any adverse events they may have experienced Performance status evaluation (questions about their activity level) Quality of life assessment questionnaire Blood will be drawn for routine laboratory tests Urinalysis Oxygen saturation measurement using a finger light sensor EKG ARQ761 Administration via intravenous (IV) for approximately 120 minutes Clinic Visit: 3 - 3 ½ Hours Combination Therapy: Cycle 1 Day 1 Vital signs Review of medical history and physical exam Performance status evaluation (questions about their activity level) Toxicity evaluation (questions about their side effects) Quality of life assessment questionnaire Blood work Blood for correlative studies Urinalysis EKG Oxygen saturation measurement using a finger light sensor Combination Treatment regimen: Nab-Paclitaxel administered via intravenous (IV) over 30 minutes then;
