Brief Summary:
The investigators' long-term goal is to improve the survival of patients with pancreatic cancer by enhancing the efficacy of gemcitabine-radiation by adding the Wee1 inhibitor MK-1775.

Arm Intervention/treatment
Experimental: MK-1775/ Gemcitabine/ Radiation Therapy Drug: MK-1775
MK-1775 will be given as an oral capsule on days 1 and 2, and on days 8 and 9 of every 3-week cycle .

Drug: Gemcitabine
Gemcitabine 1000mg/m2 will be infused over 30 minutes on days 1 and 8 of a 3 -week treatment cycle.

Radiation: Radiation Therapy
52.5Gy in 25 fractions (2.1Gy/fraction), using intensity modulated radiation therapy (IMRT). Radiation therapy will be administered after chemotherapy.

Primary Outcome Measures :
  1. Maximum Tolerated Dose (MTD) of AZD1775 (MK-1775) When Used Concurrently With Gemcitabine and Radiation Therapy. [ Time Frame: The observation period for MTD is defined as the first 4 cycles of treatment (with a 3 week break between cycle 3 and cycle 4), for a total of 105 days in length. ]
    Probability of dose limiting toxicities was calculated for each dose (p[DLT/d]) using the Time to Event Continual Reassessment Method (TITE-CRM). The target DLT rate was 0.30. Dose level 1 (150 mg AZD1775) was determined to be the MTD and recommended phase 2 dose (RP2D).

Secondary Outcome Measures :
  1. Number of Patients With Phosphorylation Inhibition of Greater Than 0 [ Time Frame: First cycle of treatment ]
    During the first cycle of treatment, patients underwent 2 biopsies: 3 h after treatment with gemcitabine (but before MK- 1775), and 2 hours after MK-1775. WEE1 signaling was assessed using immunohistochemistry (IHC) to measure phosphorylation of various markers including Cdk1 (Y15). Inhibition was quantified as the within subject change in the above markers between the two biopsy timepoints. Descriptive statistics of inhibition across subjects (for each marker) were calculated and reported by dose level.

  2. Overall Survival [ Time Frame: Up to 48 months following treatment ]
    Overall survival (OS) summarized by Kaplan-Meier curves and characterized by descriptive statistics such as median OS. The time frame for data collection for OS varied depending on the length of patient follow-up, which ranged from 1.8 months to 47.2 months. Patients who enrolled soon after the study opened may have been followed longer than patients who enrolled later, toward the end of the study.

  3. Time From Date of Registration to Date of Documented Disease Progression [ Time Frame: Up to 48 months following treatment ]
    Time from date of registration to date of documented disease progression summarized by Kaplan-Meier method. The time frame for data collection varied depending on the length of patient follow-up, which ranged from 1.8 months to 47.2 months. Patients who enrolled soon after the study opened may have been followed longer than patients who enrolled later, toward the end of the study.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients must have pathologically confirmed adenocarcinoma of the pancreas.
  • Patients will have unresectable disease, defined radiographically as >180 degrees involvement of the superior mesenteric artery or celiac trunk or SMV/portal vein impingement that cannot be surgically reconstructed, in the absence of distant metastasis..
  • Patients must have a Zubrod performance status (measure of general well being that ranges from 0 to 5 where 0 represents perfect health) of < 2.
  • Patients must have adequate organ function defined as follows: absolute neutrophil count of ≥ 1500/mm3, platelets ≥ 100,000/mm3, serum creatinine ≤ 2 mg/dl, total bilirubin ≤ 3, (with relief of biliary obstruction if present (PTC tube or endobiliary stent)) and AST < 5 times the upper limit of normal.
  • Patients of reproductive potential must agree to use an effective contraceptive method during participation in this trial and for 6 months after the trial. Patients must not be breastfeeding.
  • Patients must be aware of the investigational nature of the therapy and provide written informed consent.
  • Patients must be at least 18 years old.

Exclusion Criteria:

  • Other serious uncontrolled concomitant systemic disorders or psychiatric condition that would interfere with the safe delivery of protocol therapy.
  • A history of previous chemotherapy for pancreatic cancer or abdominal radiation therapy.
  • The use of any investigational agent in the month before enrollment into the study.
  • Inability to discontinue a prescription or non-prescription drugs or other products known to be metabolized by CYP3A4, or to inhibit or induce CYP3A4 prior to Day 1 of dosing and to withhold throughout the study until 2 weeks after the last dose of study medication. Medications of particular concern are the following inhibitors of CYP3A4: azole antifungals (ketoconazole itraconazole, fluconazole and voriconazole), macrolide antibiotics (erythromycin, clarithromycin), cimetidine, aprepitant, HIV protease inhibitors, nefazodone and the following inducers of CYP3A4: phenytoin, barbiturates and rifampicin. Substrates of CYP3A4 include statins (lovastatin, simvastatin), midazolam, terfenadine, astemizole, and cisapride.
