About this trial
This study will investigate whether or not it is feasible to closely monitor and manage glucose levels in people with pancreatic cancer. It will also investigate what impact glucose management may have on pancreatic cancer.
This is a pilot study that will use continuous glucose monitors (CGM) to monitor glucose levels in approximately 50 participants with pancreatic cancer. Participants will receive standard chemotherapy with a combination of up to four drugs to treat their pancreatic cancer: oxaliplatin, irinotecan, 5-fluorouracil, and leucovorin (FOLFIRINOX). To treat high glucose levels, participants will be randomly assigned to one of two groups: Group 1 will receive anti-hyperglycemic treatment as guided by an endocrinologist with the aim of maintaining glucose levels between 4 and 10 mmol/L; Group 2 will receive anti-hyperglycemic treatment if their glucose levels are above 15 mmol/L, which is standard care. Participants in both Groups 1 and 2 will receive standard anti-hyperglycemic treatments: metformin, insulin, glucagon-like peptide-1 (GLP-1) receptor agonists, sodium glucose co-transporter (SGLT2) inhibitors, and dipeptidyl peptidase 4 (DPP-4) inhibitors.
After 4 cycles of FOLFIRINOX, the CGM will be removed but any anti-hyperglycemic treatments will continue as needed. If participants discontinue treatment with FOLFIRINOX, they will continue to be followed for survival and subsequent anti-cancer therapy and will continue follow-up for glucose-related concerns at the discretion of their endocrinologist and/or medical oncologist.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Histological/cytological diagnosis of pancreatic ductal adenocarcinoma (PDAC).
Planned to undergo first-line systemic therapy with FOLFIRINOX.
Age greater than or equal to 18 years.
Eastern Cooperative Oncology Group (ECOG) performance status 0-1.
Disqualifiers
Absence of distant or lymph node metastases. Participants with borderline resectable or locally advanced PDAC are not eligible.
Received prior systemic therapy (chemotherapy or any other anti-cancer agent) for treatment of metastatic PDAC. Participants who received adjuvant chemotherapy after surgical resection of early stage disease are eligible.
Currently receiving anti-cancer therapy (chemotherapy or any other anti-cancer agent).
Not fit for combination chemotherapy as judged by the study doctor.

Parallel
Treatments tested in this trial
Endocrinologist-directed target blood glucose level 4-10 mmol/L using data from a continuous glucose monitor (CGM)
Procedure/SurgeryStandard anti-hyperglycemic treatment given as directed by an endocrinologist to maintain blood glucose level within 4-10 mmol/L based on data from a continuous glucose monitor (CGM) and standard blood work drawn prior to each cycle of chemotherapy. Participants will have access to their glucose data from the CGM.
Standard Care
Other interventionStandard anti-hyperglycemic treatment given only if blood glucose level is greater than 15 mmol/L as measured from standard blood work drawn prior to each cycle of chemotherapy. Participants will wear a continuous glucose monitor (CGM) but will not have access to their glucose data. Participants may be referred to an endocrinologist at the discretion of their medical oncologist.
Treatment groups
Trial outcomes
Primary outcomes
Frequency of glucose levels maintained within range in Arm 1 compared to Arm 2
The percentage of time each participant's glucose levels in Arm 1 and Arm 2 remained within the 4-10 mmol/L range during the fourth cycle of FOLFIRINOX treatment as measured by a continuous glucose monitor.
Secondary outcomes
Overall response rate (ORR) in each study arm, as defined by RECIST 1.1
The proportion of participants in each study arm who have a complete response (CR) or partial response (PR) to FOLFIRINOX treatment, as defined by RECIST 1.1.
Progression-free survival (PFS) in each study arm from the initiation of FOLFIRINOX
The length of time from the first dose of FOLFIRINOX until the date of progressive disease (PD), as defined by RECIST 1.1, for participants in each study arm.
Overall survival (OS) in each study arm from the initiation of FOLFIRINOX
The length of time from the initiation of FOLFIRINOX that participants survive in each study arm.
Other outcomes
Overall response rate (ORR) in each study arm, as defined by RECIST 1.1 and stratified by prognostic and metabolic gene expression subtypes of PDAC
