New drug combo aims to tackle deadly pancreatic cancer

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Age ≥ 18 years at the time of screening. 2. Written informed consent and any locally required authorization (eg, data privacy) obtained from the patient prior to performing any protocol-related procedures, including screening evaluations. 3. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 at the time of screening. 4. Must have life expectancy ≥ 12 weeks at the time of screening. 5. Histologically or cytologically confirmed PDAC: Eligible histological variants include: mucinous adenocarcinoma, independent cell adenocarcinoma, adenosquamous carcinoma, adenocarcinoma not otherwise specified (NOS). 6. Dose Escalation: All patients with metastatic PDAC will be permitted to enrol. 7. Dose Expansion: Patients with metastatic basal-like PDAC will be permitted to enrol, based on the PurIST assay or by transcriptomic sequencing. Patients will be permitted to start no more than one cycle of gemcitabine/nab-paclitaxel while waiting for transcriptional subtype results in the dose expansion cohort. 8. Radiographic evidence of metastatic disease that is measurable per RECIST 1.1. 9. Adequate organ and marrow function within 28 days prior to dosing on Day 1. 10. Adequate liver function (AST ≤2.5 times the institutional upper limit of normal, total bilirubin ≤2 times the institutional upper limit of normal) at the baseline visit. Patients are permitted to enroll with biliary obstruction, as long as they undergo appropriate biliary decompression (can be done at the same time as endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB)) and hepatic parameters have improved at time of baseline visit. 11. Patients must have either de novo metastatic disease or recurrence \>6 months after completion of neoadjuvant or adjuvant intent systemic therapy. 12. Patients must have recovered to ≤ Grade 1 in terms of toxicity from prior treatments at the time of enrollment (excluding neuropathy which can be ≤ Grade 2, and alopecia) 13. Patients must be able to take oral medications. 14. Females of childbearing potential who are sexually active with a nonsterilized male partner must use at least one highly effective method of contraception from screening to 180 days after the final dose of study treatment. It is strongly recommended for the male partner of a female patient to also use male condom plus spermicide throughout this period. Cessation of contraception after this point should be discussed with a responsible physician. Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception. 15. Nonsterilized male patients who are sexually active with a female partner of childbearing potential must use a male condom with spermicide from screening to 180 days after receipt of the final dose of study treatment. It is strongly recommended for the female partner of a male patient to also use a highly effective method of contraception throughout this period. In addition, male patients must refrain from sperm donation while on study and for 180 days after the final dose of study treatment. Exclusion Criteria: 1. Participants receiving any other study agents concurrently with the study drugs. 2. Known homologous recombination deficient pancreatic cancer, including germline or somatic BRCA1/2 or PALB2 mutations 3. Concurrent enrolment in another therapeutic clinical study. Enrolment in observational or supportive care studies will be allowed. 4. History of a malabsorption syndrome or uncontrolled nausea, vomiting, or diarrhea that may interfere with the absorption of oral study medication in the opinion of the investigator. 5. Patients with a history of Grade 3 or greater thromboembolic events in the prior 3 months to the scheduled first dose of study treatment or thromboembolic event of any grade with ongoing symptoms. 6. Patients with prior history of myocardial infarction, transient ischemic attack, congestive heart failure ≥ Class 3 based on New York Heart Association Functional Classification or stroke within the past 3 months prior to the scheduled first dose of study treatment. 7. Known active hepatitis infection, positive hepatitis C virus (HCV) antibody, hepatitis B virus (HBV) surface antigen (HBsAg) or HBV core antibody (anti-HBc), at screening. Participants with a past or resolved HBV infection (defined as the presence of anti HBc and absence of HBsAg) are eligible. Participants positive for HCV antibody are eligible only if polymerase chain reaction is negative for HCV RNA. 8. Known to have tested positive for human immunodeficiency virus (HIV) (positive HIV 1/2 antibodies) or active tuberculosis infection (clinical evaluation that may include clinical history, physical examination and radiographic findings, or tuberculosis testing in line with local practice). 9. Other invasive malignancy within 2 years. Non-invasive malignancies (ie, cervical carcinoma in situ, in situ prostate cancer, non-melanomatous carcinoma of the skin, ductal carcinoma in situ of the breast that has been surgically cured) are excluded from this definition. Malignancy treated with curative intent and with no known active disease ≥2 years before the first dose of study treatment and of low potential risk for recurrence are permitted. 10. Known allergy or hypersensitivity to investigational product formulations. 11. Active grade 3 or greater edema (eg, peripheral, pulmonary). 12. Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the patient to give written informed consent. 13. Participants with known untreated brain metastases are excluded. Patients with a history of brain metastases are permitted to enroll if they have been treated and have been stable for a minimum of one month on imaging. Participants must be off all corticosteroids at the time of enrolment. 14. Major surgery (as defined by the investigator) within 28 days prior to scheduled first dose of study treatment or still recovering from prior surgery. Local procedures (eg, placement of a systemic port, core needle biopsy, etc) are allowed, without needing to wait for the 28 day recovery period. 15. Females who are pregnant, lactating, or intend to become pregnant during their participation in the study. 16. Any condition that, in the opinion of the investigator, would interfere with safe administration or evaluation of the investigational products or interpretation of patient safety or study results.
