Monitoring and Managing Glucose Levels in People With Pancreatic Cancer
Sponsor:

British Columbia Cancer Agency

Brief Summary:

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.

Hyperglycemia

Intervention/treatment

Endocrinologist-directed target blood glucose level 4-10 mmol/L using data from a continuous glucose monitor (CGM)

Standard Care

Phase

Not Applicable

Study Type : Interventional
Estimated Enrollment : 50 participants
Masking : Single
Masking Description : Participants in Group 1 can view their glucose data in real-time from the continuous glucose monitor (CGM) whereas participants in Group 2 cannot. Participants in Groups 1 and 2 will NOT be masked to the anti-cancer or anti-hyperglycemic treatment they receive.
Primary Purpose : Treatment
Official Title : Pancreatic Cancer Glucose Assessment and Regulation Study
Actual Study Start Date : April 16, 2024
Estimated Primary Completion Date : April 2026
Estimated Study Completion Date : April 2027
Arm Intervention/treatment

Experimental: Intensive Glucose Intervention

Participants will receive standard anti-hyperglycemic treatment as guided by an endocrinologist using a combination of data from a continuous glucose monitor (CGM) and standard blood work drawn prior to each cycle of chemotherapy. Treatment will aim to maintain glucose levels between 4 and 10 mmol/L. Participants will have real-time access to their glucose data via the CGM.

Procedure: Endocrinologist-directed target blood glucose level 4-10 mmol/L using data from a continuous glucose monitor (CGM)

Other: Standard Care

Participants will receive standard anti-hyperglycemic treatment only if blood glucose level is above 15 mmol/L as measured from standard blood work drawn prior to each cycle of chemotherapy. Participants will wear a CGM but will not be able to view their glucose data. Participants may be referred to an endocrinologist at the discretion of their medical oncologist.

Other: Standard Care

  • Adequate bone marrow and organ function as defined by the following laboratory values
    • Absolute neutrophil count (ANC) greater than or equal to 1.5 x 10^9/L.
    • Platelet count greater than or equal to 75 x 10^9/L.
    • Hemoglobin greater than or equal to 9.0 g/dL.
    • Estimated glomerular filtration rate (GFR) by Cockroft-Gault equation OR 24 hour urine collection greater than or equal to 40 ml/min.
    • Creatinine clearance greater than or equal to 40 mL/min using Cockcroft-Gault formula.
    • Potassium within normal limits, or corrected with supplements.
    • International normalized ratio (INR) less than or equal to 1.5.
    • Total serum bilirubin less than or equal to 2 x upper limit of normal (ULN) (any elevated bilirubin should be asymptomatic at enrollment) except for participants with documented Gilbert's syndrome who may only be included if the total bilirubin less than or equal to 3 x ULN or direct bilirubin less than or equal to 1.5 x ULN).
    • Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) less than or equal to 2.5 x ULN (or less than or equal to 5 x ULN if liver metastases are present).
