Yes No Not Sure

Inclusion Criteria

Histologically or cytologically confirmed metastatic PDAC
Has received 1 prior gemcitabine-based chemotherapy as first line therapy for metastatic disease. Progression after completion of neoadjuvant or adjuvant therapy of < 6 months in duration is considered 1 line of therapy for metastatic disease
Has measurable disease according to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1), defined as at least 1 lesion that can be accurately measured in at least 1 dimension (longest diameter to be recorded) as > 20 mm with conventional techniques or as > 10 mm with spiral computed tomography (CT) scan
Eastern Cooperative Oncology Group (ECOG) Performance Status 0-1
Must be willing and able to undergo a tissue biopsy at screening; participants who, in the opinion of the investigator, do not have tissue that is accessible for biopsy are excepted from this criterion
Women of childbearing potential: (defined as not post-menopausal for 12 months or no previous surgical sterilization) and fertile men must agree to use adequate contraception for the duration of study participation and for 4 months after the last dose of nal-IRI. Male subjects must agree to refrain from sperm donation during the study and for 4 months after the last dose of nal-IRI
Ability to understand and the willingness to sign a written informed consent document. Signed informed consent form must be obtained prior to initiation of study evaluations and/or activities
International Normalized Ratio (INR) < 1.5 unless on warfarin
Participants with prior malignancy and who were treated with no evidence of active disease more than 2 years from initial diagnosis are eligible
Age ≥ 18 years
Participants must have adequate organ and bone marrow function

Exclusion Criteria

Prior treatment with irinotecan, nal-IRI, or investigational PLK1 inhibitor
Uncontrolled intercurrent illness including symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, and myocardial infarction within 3 months of initiation of therapy
History of interstitial pneumonitis or interstitial lung disease
Participants with microsatellite instability-high (MSI-H) tumors with no prior immune checkpoint inhibitor exposure
Pregnancy or lactation
Participant has active and uncontrolled bacterial, viral, or fungal infection(s) requiring systemic therapy
QT interval with Fridericia's correction (QTcF) > 470 milliseconds. The QTcF should be calculated as the arithmetic mean of the QTcF on triplicate electrocardiograms (ECGs). In the case of potentially correctible causes of QT prolongation, (eg, medications, hypokalemia), the triplicate ECG may be repeated once during Screening and that result may be used to determine eligibility
Planned concomitant use of medications known to prolong the QT/QTc interval
Participant has undergone major surgical resection within 4 weeks prior to enrollment
Participant received radiotherapy, surgery, chemotherapy, or an investigational therapy within 2 weeks prior to study entry
Participant has serious medical risk factors involving any of the major organ systems such that the investigator considers it unsafe for the participant to receive an experimental research drugs
Serious psychiatric or medical conditions that could interfere with treatment
Major bleeding in the last 4 weeks
More than 1 prior chemotherapy regimen administered in the metastatic setting
Unable or unwilling to swallow oral medication
Use of strong CYP3A4 or UGT1A1 inhibitors or strong CYP3A4 inducers. Participants currently receiving these agents who are able to switch to alternate therapy are not excluded. Inhibitors should be stopped at least one week prior to the first dose of protocol therapy and inducers should be stopped at least two weeks prior to initiation of protocol therapy
