The purpose of this Phase 1b study is to investigate whether intravenous administration of REOLYSIN® in combination with chemotherapy and pembrolizumab is effective and safe in the treatment of pancreatic adenocarcinoma.

Study summary:

Reovirus Serotype 3 - Dearing Strain (REOLYSIN®) is a naturally occurring, ubiquitous, non-enveloped human reovirus. It's primary mode of activity is to infect and selectively target tumors with activating Ras pathway mutations. Up to 70% of pancreatic cancers have activating Ras pathway mutations and/ or over-expressions. This is an open label, Phase 1b study of REOLYSIN® and chemotherapy in combination with pembrolizumab in patients with advanced (unresectable or metastatic) histologically confirmed pancreatic adenocarcinoma that progressed after (or did not tolerate) first-line therapy. It is thought that Reovirus when combined with chemotherapy would lead to increased viral replication and oncolysis preferentially in RAS activated tumors, with resulting immunogenic response than can be further enhanced by checkpoint inhibition using pembrolizumab. The study is designed to characterize the efficacy and safety of REOLYSIN® given intravenously in combination with one of the three chemotherapy backbone regimens, Gemcitabine, Irinotecan or Leucovorin/ 5-fluorouracil (5-FU), and pembrolizumab, the treatment cycle of which will be repeated every 3 weeks. It will follow a 3+3 design with no dose escalations. 3 patients will be initially enrolled. If no dose limiting toxicities (DLT) are observed, the cohort will be expanded. Provided patients do not develop intolerable toxicity (that does not respond to either supportive care or dose reduction) or clinically meaningful disease progression, treatment with additional cycles may be continued so long as patients experience clinical benefit in the judgement of the Investigator.


Inclusion Criteria: Each patient MUST: - Have histologically confirmed advanced or metastatic pancreatic adenocarcinoma and have failed or did not tolerate first-line therapy. - Have either archival tissue available for immune testing OR if not, a baseline biopsy of a primary or metastatic lesion (including ascites) which is accessible for a biopsy that can be accomplished with reasonable safety. - Be available and agree to; a post-treatment tumor biopsy of either a primary or metastatic lesion (including ascites). - Have measurable disease. - Have no continuing acute toxic effects (except alopecia) of any prior anticancer treatment, i.e., all such effects must have resolved to Common Terminology Criteria for Adverse Events (CTCAE), version 4.02 [2], Grade ≤1. Any major surgery (except biopsies) must have occurred at least 28 days prior to study enrolment. - Have an ECOG Performance Score ≤ 2. - Have baseline laboratory results as follows: - Absolute neutrophil count (ANC) ≥ 1.5 x 10E9 [SI units 10E9/L]. - Platelets ≥ 100 x10E9 [SI units 10E9/L] (without platelet transfusion) - Serum creatinine ≤ 1.5 x ULN. - Creatinine clearance (measured over 24 hours) OR calculated creatinine clearance (Cockcroft-Gault formula) of ≥ 60 mL/min. - Bilirubin ≤ 1.5 x ULN. - AST/ALT ≤ 3 x ULN (≤ 5 x ULN if patients have liver metastasis). - TSH, T4 and ACTH must be within normal range. - Proteinuria with normal or grade 1 OR Urinary protein < 1 g/24hr. - Negative pregnancy test for females of childbearing potential. - Have signed an informed consent indicating that the patient is aware of the neoplastic nature of their disease and have been informed of the procedures of the protocol, the experimental nature of the therapy, alternatives, potential benefits, side effects, risks, and discomforts. - Be willing and able to comply with scheduled visits, the treatment plan, and laboratory tests. Exclusion Criteria: Each patient MUST NOT: - Receive concurrent therapy with any other investigational anticancer agent while on study. - Be on immunosuppressive therapy or have known HIV infection or active hepatitis B or C. - Receive radiotherapy within 28 days prior to receiving study drug. - Be a pregnant or breast-feeding woman. Female patients of childbearing potential must agree to use effective contraception, must be surgically sterile, or must be postmenopausal. Male patients must agree to use effective contraception or be surgically sterile. Barrier methods are a recommended form of contraception. - Have clinically significant cardiac disease (New York Heart Association, Class III or IV) including pre-existing arrhythmia, uncontrolled angina pectoris, myocardial infarction 1 year prior to study entry, or grade 2 or higher compromised left ventricular ejection fraction. - Have dementia or altered mental status that would prohibit informed consent. - Have any other severe, acute, or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration or may interfere with the interpretation of study results and, in the judgment of the Principal Investigator, would make the patient inappropriate for this study. - Have HIGH BURDEN/SYMPTOMATIC brain metastases. LOW VOLUME / ASYMPTOMATIC and pre-treated clinically stable brain metastases ARE allowed.
