Detailed Description

Pancreatic cancer is an aggressive and lethal disease. Even two combination regimens, FOLFIRINOX and albumin-bound paclitaxel in combination with gemcitabine, are superior to gemcitabine alone as the first-line treatments, the prognosis of patients with locally advanced or metastatic pancreatic cancer remains poor, with a median overall survival of 8 to 11 months and an estimated 2-year survival of only 2%. Even more, there is currently no available treatment proven beneficial for patients who fail the second-line therapy with liposomal irinotecan in combination with 5-FU.

Immune checkpoint inhibitors targeting PD-1 or PD-L1 represent a popular treatment option for patients with some kinds of cancers, but previous studies in pancreatic cancer have failed. One critical challenge for immunotherapy in pancreatic cancer is to find efficient therapeutic approaches to reverse this "cold" tumor into a "hot" tumor. Our previous basic studies revealed that all-trans retinoic acid repressed pancreatic adenocarcinoma cell growth and colony formation. Set-to-set genetic analysis revealed that genes regulated by all-trans retinoic acid were predominantly involved in immune response including interleukin-6, tumor necrotic factor-α, IFNs signaling, and PD-L1. Furthermore, mice bearing pancreatic cancer treated with combination of anti-PD-1 and all-trans retinoic acid had a significantly longer survival compared to mice treated with anti-PD-1 or all-trans retinoic acid alone.

Based on the previous findings, we propose this pilot, compassionate use of combination therapy with all-trans retinoic acid and nivolumab for patients with locally advanced or metastatic pancreatic adenocarcinoma who are refractory to current available treatment. This study will also examine ADAR1 as a novel prognostic and predictive biomarker for pancreatic adenocarcinoma patients. This study will help to delineate the role of ADAR1 as a predictive biomarker for immunotherapy, all-trans retinoic acid as a suppressor of ADAR1, and most importantly, the combination of all-trans retinoic acid and nivolumab as an effective anticancer therapy for patients with pancreatic adenocarcinoma.

Patients will be included in the study if they meet all of the following criteria:

  1. Patients with age ≥ 20 years old
  2. Histologically confirmed pancreatic adenocarcinoma
  3. Unresectable locally advanced, recurrent or metastatic diseases ineligible or unsuitable for further surgical or radiation interventions
  4. Documented disease progression within 6 months after standard chemotherapies or no available standard chemotherapy. The standard chemotherapies include gemcitabine, nab-paclitaxel, S-1, and FOLFIRINOX. Patient who has prior anti-PD1/anti-PD-L1 treatment will not be eligible.
  5. ECOG Performance Status 0-2
  6. Documented measurable disease as defined by RECIST v1.1

  7. Adequate hematologic parameters, and hepatic and renal functions defined as

    1. absolute neutrophil count ≥ 1,000/μL
    2. platelets ≥ 75,000/μL
    3. total bilirubin ≤ 2.5X ULN (≤ 5X ULN if attributable to liver metastases)
    4. AST/ALT ≤ 2.5X ULN (≤ 5X ULN if attributable to liver metastases)
    5. serum creatinine ≤ 2 mg/dL or creatinine clearance ≥ 30 mL/min (by calculated or 24-hour urine collection)
  8. Normal ECG or ECG without any clinical significant findings
  9. Able to understand and sign an informed consent (or have a legal representative who is able to do so)

Exclusion Criteria:

Patients will be excluded from the study if they meet any of the following criteria:

  1. History of allergic reaction to all-trans retinoic acid or nivolumab
  2. Patient with liver cirrhosis with Child-Pugh score ≥ 8 (Late Child-Pugh B and Child-Pugh C)
  3. Active CNS metastasis defined by clinical symptoms, cerebral edema, steroid or anti-convulsant requirement, or progressive growth. Patients with a history of CNS metastasis or cord compression are allowed in the study if they have been treated and are clinically stable
  4. With clinically significant gastrointestinal disorder including bleeding, inflammation, occlusion or diarrhea > grade 1

  5. With uncontrolled intercurrent illness that could limit study compliance or judged to be ineligible for the study by the investigators including, but not limited to, any of the following:

    1. ongoing or active infection requiring antibiotic treatment
    2. symptomatic congestive heart failure, unstable angina pectoris, or cardiac arrhythmia
    3. psychiatric illness or social situation that would preclude study compliance
  6. Pregnant or breast feeding women (a urine pregnancy test must be performed on all patients who are of childbearing potential before entering the study, and the result must be negative)
  7. Patients taking the following medications: immunosuppressants, corticosteroids with the exception of administration topically (e.g., external, intra-articular, intranasal, ophthalmic, or inhalational use) or temporarily (e.g., for treatment or prophylaxis of contrast medium allergy or adverse events), antitumor therapies (e.g., chemotherapies, molecular-targeted therapies, immunotherapies), radiopharmaceuticals with the exception of diagnostic purposes, transplant therapies, vitamin A, antifibrinolytic agents (tranexamic acid, aminocaproic acid, aprotinin), inducers (rifampicin, glucocorticoids, phenobarbital and pentobarbital) or inhibitors (ketoconazole, cimetidine, erythromycin, verapamil, diltiazem and cyclosporine) of the hepatic P450 system, and other unapproved drugs (e.g., investigational use of drugs, unapproved combined formulations, unapproved dosage forms).

  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Nivolumab + all-trans retinoic acid

Nivolumab: 3mg/kg intravenously on day 1.

All-trans retinoic acid (Vesanoid) 45 mg/m2 on days 1-14. The dose of Vesanoid can be increased with addition of 15 mg/m2 in next course of treatment if there is no severe adverse effects. Therefore, the dose of Vesanoid could be 60 mg/m2 from the second course, 75 mg/m2 from the third course, till the maximal dose of 150 mg/m2 if patients tolerated the treatment. The decision of dose escalation is left to in-charge physician.

The treatment cycle will repeat every 2 weeks.
Drug: Nivolumab
Nivolumab, an immune checkpoint inhibitors targeting PD-1, represents a popular treatment option for patients with cancers via immunological mechanism. However, previous studies using nivolumab alone in pancreatic cancer have failed.
Other Names:
  • Opdivo
Drug: all trans retinoic acid
Our previous basic studies revealed that all-trans retinoic acid repressed pancreatic adenocarcinoma cell growth and colony formation. All-trans retinoic acid represses ADAR1, a member of interferon-stimulated genes and a negative regulator of IFNs signaling. On the other hand, all-trans retinoic acid simultaneously increases PD-L1 expression for cancer cells to evade immune surveillance. Since combination of anti-PD1 antibody and all-trans retinoic acid may block self-regulating negative feedback loops of IFNs response, this therapeutic strategy may improve outcomes of pancreatic adenocarcinoma patients.
Other Names:
  • Vesanoid
