Details and patient eligibility


<Research Hypothesis> The dynamics of immune cells by CCRT/Durvalumab will be uncovered. The combination of Durvalumab with concurrent chemoradiotherapy (CCRT/gemcitabine)) as neoaduvant treatment in resectable or borderline resectable pancreatic cancer is feasible and efficacious.

The combination of Durvalumab with cytotoxic chemotherapy (gemcitabine) as an adjuvant treatment is feasible and efficacious.

<Objectives> To assess the effect of Neoadjuvant CCRT with Gemcitabine/Durvalumab followed by adjuvant Gemcitabine/Durvalumab in resectable or borderline resectable pancreatic cancer

Primary endpoint:

2 year-DFSR (disease-free survival rate) Secondary endpoints

  • Efficacy: 2 year-OSR (overall survival rate), disease-free survival, overall survival, overall response rate (RECIST 1.1, ir response) after neoadjuvant CCRT, disease control rateEORTC QLQ-C30, the number of immune cells (TIL, macrophage, etc) in resected pancreatic tissue
  • Safety: toxicity (CTCAE V), irAE,

Exploratory Objective(s):

  • To evaluate baseline measures and changes of immune systems and regulations by neoadjuvant CCRT with gemcitabine/Durvalumab in peripheral blood and tumor tissues
  • To collect and store DNA from blood (according to ethical procedures) for future exploratory research into genes/genetic variation that may influence response (ie, distribution, safety, tolerability and efficacy) to study treatments and or susceptibility to disease (optional).

Exclusion criteria

  1. Participation in another clinical study with an investigational product during the last 3 weeks 26. Concurrent enrolment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study 27. Any previous treatment with a PD1 or PD-L1 inhibitor, including durvalumab 28. Receipt of the last dose of anti-cancer therapy (chemotherapy, immunotherapy, endocrine therapy, targeted therapy, biologic therapy, tumor embolization, monoclonal antibodies, other investigational agent) 28 days prior to the first dose of study drug 29. Mean QT interval corrected for heart rate (QTc) ≥470 ms calculated from 3 electrocardiograms (ECGs) using Fridericia's Correction (this can be removed if testing durvalumab alone and retain this exclusion if combining durvalumab with novel agents) 30. Current or prior use of immunosuppressive medication within 14days (use 28 days if combining durvalumab with a novel agent) before the first dose of durvalumab, with the exceptions of intranasal and inhaled corticosteroids or systemic corticosteroids at physiological doses, which are not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid. The following are exceptions to this criterion:
  • Intranasal, inhaled, topical steroids, or local steroid injections (eg, intra articular injection)
  • Systemic corticosteroids at physiologic doses not to exceed <<10 mg/day>> of prednisone or its equivalent

  • Steroids as premedication for hypersensitivity reactions (eg, CT scan premedication) 31. Any unresolved toxicity NCI CTCAE Grade ≥2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria

  • Subjects with Grade ≥2 neuropathy will be evaluated on a case-by-case basis after consultation with the Study Physician.

  • Subjects with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the Study Physician.

    1. Any concurrent chemotherapy, IP, biologic, or hormonal therapy for cancer treatment. Concurrent use of hormonal therapy for non-cancer-related conditions (eg, hormone replacement therapy) is acceptable. <<amend as required based on any combination studies with other anti-cancer agents>> 33. <<if applicable to the study>>Radiotherapy treatment to more than 30% of the bone marrow or with a wide field of radiation within 4 weeks of the first dose of study drug 34.
