Brief Summary:
The standard or usual treatment for this disease consists of two chemotherapy drugs gemcitabine and nab-paclitaxel given together.

Condition or disease Intervention/treatment Phase
Pancreatic Adenocarcinoma Drug: Gemcitabine Drug: Nab-paclitaxel Drug: Durvalumab Drug: Tremelimumab Phase 2

Detailed Description:

Durvalumab is a new type of drug for many types of cancer. Laboratory tests show that it works by allowing the immune system to detect cancer and reactivate the immune response. This may halp to slow down the growth of cancer or may cause cancer cells to die. Durvalumab has been shown to shrink tumours in animals and has been studied in a few people and seems promising but it is not clear if it can offer better results than standard treatments alone.

Tremelimumab is a new type of drug for various types of cancers. It works in a similar way to durvalumab and may improve the effect of durvalumab. This may also help slow the growth of the cancer cells or may cause cancer cells to die. Tremelimumab has been shown to shrink tumours in animals and has been studied in a few people and seems promising but it is not clear if it can offer better results than standard treatment alone when used with durvalumab.

Combination of durvalumab and tremelimumab have also been studied and when combined have been shown to increase tumour shrinkage in animals compared to either drug alone and while the combination has been studied in a few people, it is not clear if it can offer better results than standard treatment.

Primary Outcome Measures :
  1. Overall survival (Phase III) [ Time Frame: 35 months ]

Secondary Outcome Measures :
  1. Progression free survival defined as the time from randomization to the first objective documentation of disease progression or death due to any cause [ Time Frame: 35 months ]
  2. Objective response rate defined as the proportion of patients with a documented complete response and partial response based on RECIST 1.1 [ Time Frame: 35 months ]
  3. Number and severity of adverse events [ Time Frame: 35 months ]
    The incidence of adverse events will be summarized by type of adverse event and severity using the NCI Common Terminology Criteria for Adverse Events. A Fisher's exact test will be used to compare adverse events between the two arms if required

Layout table for eligibility information
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 histologically or cytologically confirmed pancreatic ductal adenocarcinoma which is metastatic.
  • Must have presence of measurable or evaluable disease as defined by Response Evaluation Criteria in Solid Tumours (RECIST 1.1).
  • Patients must be considered suitable candidates for, and able to receive, first line chemotherapy for metastatic disease with gemcitabine and nab-paclitaxel.
  • Patient must consent to provision of, and investigator(s) must confirm access to and agree to submit within 4 weeks of randomization to the CCTG Central Tumour Bank, a representative formalin fixed paraffin block of tumour tissue of adequate amount and quality in order that the specific correlative marker assays proscribed in the protocol may be conducted.
  • Patient must consent to provision of samples of blood, serum and plasma in order that the specific correlative marker assays proscribed may be conducted.
  • Patients must be ≥ 18 years of age.
  • Patients must have an ECOG performance status of 0 or 1 with a life expectancy of at least 12 weeks.
  • No prior treatment for metastatic disease is permitted. Patients may have received prior adjuvant chemotherapy if the last dose was given more than 6 months prior to recurrence. Patients may not have received chemoradiotherapy or adjuvant radiation therapy. Patient may not have received nab-paclitaxel as adjuvant therapy. Prior systemic treatment for borderline resectable or locally advanced disease is not permitted. Patients receiving a single dose of radiation (up to 8Gy/800RAD) with palliative intent for pain control are eligible provided a minimum of 14 days have elapsed between the radiation and the date of randomization.
  • Adequate normal organ and marrow function as defined below (must be done within 14 days prior to registration).

Absolute neutrophils ≥ 1.5 x 10^9/L Platelets ≥ 100 x 10^9/L Hemoglobin ≥90 g/L Bilirubin ≤ 1.5 x upper normal limit AST and ALT ≤ 2.5 x upper normal limit Serum creatinine <1.25 UNL or Creatinine clearance ≥40mL/min

  • Imaging investigations including CT/MRI of chest/abdomen/pelvis or other scans as necessary to document all sites of disease done within 28 days prior to randomization.
  • Patient is able (i.e. sufficiently fluent) and willing to complete the quality of life questionnaires in either English or French.
  • Patient consent must be appropriately obtained in accordance with applicable local and regulatory requirements.
  • Patients must be accessible for treatment and follow-up. Patients registered on this trial must be treated and followed at the participating centre. Patients must agree to return to the participating centre for management of any adverse events which may occur through the course of the trial. This implies there must be reasonable geographical limits placed on patients being considered for this trial. Sites are encouraged to contact CCTG (or their respective Cooperative Group for sites outside Canada) for any questions regarding the interpretation of this criterion. Investigators must assure themselves the patients randomized on this trial will be available for complete documentation of the treatment, adverse events, and follow-up.
  • In accordance with CCTG policy, protocol treatment is to begin within 2 working days of patient randomization.
  • Women/men of childbearing potential must have agreed to use a highly effective contraceptive method

Exclusion Criteria:

  • Patients with a history of other malignancies, except: adequately treated non-melanoma skin cancer, curatively treated in-situ cancer of the cervix, or other solid tumours curatively treated with no evidence of disease for ≥ 5 years. Patients with a history of other malignancies detected at an early stage and whom the investigator believes have been curatively treated and are at a low risk of recurrence MAY be eligible. Contact CCTG to discuss eligibility prior to enrolling.
  • Any previous treatment with a PD1 or PD-L1 inhibitor, including durvalumab or an anti-CTLA4, including tremelimumab.
  • History of primary immunodeficiency, history of organ transplant that requires therapeutic immunosuppression or prior history of severe (grade 3 or 4) immune-mediated toxicity from other immune therapy.
