Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patients must have pathologically confirmed adenocarcinoma of the pancreas.

  • 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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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).
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.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
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.
First cycle of treatment
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.
Up to 48 months following treatment
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.
Up to 48 months following treatment
