Brief Summary:
This is an open-label, multi-centre, randomised, stratified, phase IIb clinical trial of ATRA administered in combination with gemcitabine and nab-paclitaxel in patients with laPDAC.

Condition or disease Intervention/treatment Phase
Pancreatic Cancer Drug: ATRA Drug: Gemcitabine Drug: nab-paclitaxel Phase 2

Detailed Description:
Patients will be randomised to receive gemcitabine + nab-paclitaxel or gemcitabine + nab-paclitaxel + ATRA. Treatment will be administered in 28 day cycles. ATRA will be administered for 6 cycles whereas gemcitabine/nab-paclitaxel will be administered until disease progression. Treatment may be discontinued earlier due to unacceptable toxicities or death or because the patient requests to be withdrawn from study treatment. If treatment with gemcitabine/nab-paclitaxel is stopped prior to the patient completing 6 cycles of treatment with ATRA (if allocated), the patient may continue on treatment with ATRA alone until the 6 cycles are completed, at the discretion of the treating physician.

Primary Outcome Measures :
  1. To assess the efficacy of ATRA when given in combination with gemcitabine and nab-paclitaxel based on progression free survival (PFS). [ Time Frame: Assessed 8 weekly until progression or death ]
    PFS defined as the time from the date of randomisation to the date of first documented tumour progression or death from any cause, whichever occurs first.


Secondary Outcome Measures :
  1. To assess the efficacy of ATRA when given in combination with gemcitabine and nab-paclitaxel based on objective response rate (ORR). [ Time Frame: Assessed 8 weekly until progression or death ]
    ORR defined as the number of patients with an objective response (OR) divided by the number of patients analysed. OR is defined as the number of patients with at least one confirmed response of complete response (CR) or partial response (PR). OR will be calculated in patients with measurable disease at baseline.

  2. To assess the efficacy of ATRA when given in combination with gemcitabine and nab-paclitaxel based on overall survival (OS). [ Time Frame: Assessed 8 weekly until progression or death and then 3 monthly for at least 12 months after the last safety visit ]
    OS is defined as the time from the date of randomisation to death from any cause.

  3. To assess the safety and tolerability of ATRA when given in combination with gemcitabine and nab-paclitaxel over the first 6 cycles. [ Time Frame: 6 cycles (1 cycle = 28 days) ]
    Safety and tolerability as assessed by AEs (CTCAE v5.0).

  4. To assess the surgical resection rate of ATRA when given in combination with gemcitabine and nab-paclitaxel. [ Time Frame: From consent to at least 12 months after the last safety visit, but further if required as per physician decision. ]
    Surgical resection rate defined as patients undergoing complete resection of known pancreatic primary and associated lymph nodes at any point after enrolment, in each arm.

  5. To assess the resection margin negative (R0) surgical resection rate of ATRA when given in combination with gemcitabine and nab-paclitaxel. [ Time Frame: From consent to at least 12 months after the last safety visit, but further if required as per physician decision. ]
    R0 surgical resection rate defined as histologically confirmed complete resection of known pancreatic primary from those resected.

  6. To assess quality of life (QOL) of patients receiving ATRA in combination with Gemcitabine and Nab-Paclitaxel: EQ-5D-5L [ Time Frame: Assessed at the beginning of each cycle until progression (1 cycle = 28 days) ]
    Patient reported outcomes as measured by questionnaire EQ-5D-5L

Ages Eligible for Study:   16 Years and older   (Child, Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

Each patient must meet all of the following inclusion criteria to be enrolled in the study:

  1. Written informed consent prior to admission to this study
  2. Age ≥16 years. No upper age limit.
  3. ECOG performance status 0 or 1
  4. Histologically proven pancreatic ductal adenocarcinoma (PDAC) as part of the Precision-Panc Master Protocol, or for patients who have gone exploratory laparotomy and found to have locally, unresectable advanced disease.
  5. Locally advanced disease which is measurable according to the Response Evaluation Criteria in Solid Tumours (RECIST v1.1).
  6. CT chest abdomen and pelvis as well as PET-CT within 28 days of day 1 of treatment (MRI Liver only if indeterminate liver lesions) to confirm absence of metastatic disease.
  7. Received no prior systemic therapy for pancreatic cancer.
  8. Adequate haematologic and end organ function, defined by the following laboratory results obtained within 14 days prior to the first study treatment:

    1. Absolute Neutrophil Count ≥ 1.5 x 109/l (without granulocyte colony-stimulating factor support within 2 weeks prior to the first study treatment)
    2. Platelet count ≥ 100 x 109/l (without transfusion within 2 weeks prior to the first study treatment)
    3. Haemoglobin ≥ 10 g/dl (transfusion permitted to establish target haemoglobin levels prior to the first study treatment)
    4. Calculated creatinine clearance (e.g. Cockcroft-Gault) ≥ 50 ml/min
    5. Bilirubin level ≤ 1.5 ULN (patients with known Gilbert disease who have bilirubin levels ≤ 3 x ULN may be enrolled). Patients must be able to undergo biliary stenting if required before or, if required, during the trial
    6. AST or ALT <2.5 x ULN
    7. Alkaline phosphatase (ALP) <2.5 x ULN
    8. INR and aPTT ≤1.5 x ULN; this applies only to patients who are not receiving therapeutic anticoagulation; patients receiving therapeutic anticoagulation should be on a stable dose.
  9. Female patients of child-bearing potential are eligible, provided they have a negative serum pregnancy test within 7 days prior to the first dose of study treatment, preferably as close to the first dose as possible. All patients with reproductive potential must agree to use a medically acceptable method of contraception throughout the treatment period and for 1 month after discontinuation of ATRA and / or gemcitabine/nab-paclitaxel (whichever is the latest) and for 6 months after discontinuation for male patients. Acceptable methods of contraception include IUD, oral contraceptive, sub-dermal implant and double barrier (condom with a contraceptive sponge or contraceptive pessary). Micro-dosed progesterone preparations ("mini-pill") are an inadequate method of contraception during treatment with ATRA. If patients are taking this pill they should be instructed to stop and another form of contraceptive should be prescribed instead.
  10. Able to follow protocol requirements as assessed by the Principal Investigator.
