Monitoring and Managing Glucose Levels in People With Pancreatic Cancer (PEGASUS)

September 10, 2026 updated by: British Columbia Cancer Agency

Pancreatic Cancer Glucose Assessment and Regulation Study

This study will investigate the prevalence of hyperglycemia (high blood sugar) in approximately 50 participants with pancreatic cancer. Sugar levels will be monitored with blood draws prior to each cycle of anti-cancer treatment until treatment ends or the participant's cancer worsens. Participants may receive any first-line systemic therapy for pancreatic cancer, including treatments given as part of another clinical trial. If treatment is needed to manage blood sugar levels, the treatment will be given according to the standard of care. All participants will be enrolled into the same group.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Glucose Measurements via Blood Draws
Participants will have glucose levels measured using blood drawn prior to each cycle of systemic therapy.
Blood glucose levels will be measured using blood drawn prior to each cycle of systemic therapy. Anti-cancer treatment can follow standard care protocols or be given within another clinical trial. Anti-hyperglycemic treatment will be administered when indicated by and following standard care protocols.
