recruiting iconRECRUITING


The Coordinating and Data Management Center (CDMC) at MD Anderson Cancer will be responsible for the coordination and data management for the Evaluation of a mixed meal test for Diagnosis and characterization of Type 3c diabetes mellitus secondary to pancreatic cancer and chronic pancreatitis (DETECT), which is part of the NIH U01 funded Consortium for the Study of Chronic Pancreatitis, Diabetes, and Pancreatic Cancer (CPDPC). Similar to all studies that will be coordinated and managed by the CDMC, no patient enrollment will occur at MDACC. All patient recruitment will occur at external sites that are a part of the CPDPC, which are listed in the appended DETECT protocol. The data management systems, auditing, and monitoring effort are supported by the CDMC.

Official Title

Evaluation of a Mixed Meal Test for Diagnosis and Characterization and Type 3c Diabetes Mellitus Secondary to Pancreatic Cancer and Chronic Pancreatitis (DETECT)

Eligibility Criteria

Ages Eligible for Study: 30 Years to 84 Years
Sexes Eligible for Study: All
Accepts Healthy Volunteers: No
Inclusion Criteria:
  1. All patients must sign an informed consent indicating that they are aware of the investigational nature of this study. Patients must have signed an authorization for the release of their protected health information. - Patients must be ages ≥30 and <85. - Patients must have a diagnosis of one of the following based on study definitions - New Onset Diabetes (<3 years) in subjects with Pancreatic Cancer (PDAC); - New Onset Diabetes (<3 years) in subjects with Chronic Pancreatitis; - New Onset Diabetes (<3 years) in subjects without Pancreatic disease (i.e., T2DM) - Long standing T2DM (≥3 years) without Pancreatic disease - Long standing diabetes (≥3 years) in subjects with PDAC - Long standing diabetes (≥3 years) subjects with chronic pancreatitis - non-diabetic subjects with PDAC - non-diabetic subjects with chronic pancreatitis - non-diabetic controls without Pancreatic disease
Exclusion Criteria:
  1. - Subjects must not have any significant medical illnesses (including diabetes) that in the investigator's opinion cannot be adequately controlled with appropriate therapy or would compromise the patient's ability to tolerate study interventions. - Diabetes not stable enough to permit holding of diabetes medications in subjects undergoing mixed meal tolerance testing. - Subjects taking higher doses of insulin (≥0.75 unit/kg/day). - Subjects in the non-pancreatic disease subgroup (i.e., T2DM) on longer acting agents, including thiazolidinediones and once-weekly GLP-1 agonists (Bydureon [exenatide], Ozempic [semaglutide], Trulicity [dulaglutide]). Conversely, the use of these medications is permitted for subjects in the CP and PDAC groups. - Patients currently receiving oral steroid medications. - Hospitalization for acute pancreatitis within 2 months before study visit (with the exception of subjects enrolled into the PDAC group, as this may be a symptom of the disease). - The presence of a symptomatic cyst in subjects with CP. The presence of a cyst in subjects with pancreatic cancer is not an exclusion, including cancer arising from a mucinous cystic lesion. - Any subject with a known pancreatic cancer histologic subtype other than adenocarcinoma (e.g., subjects with pancreatic neuroendocrine tumors are excluded). - Previous pancreatic surgery (including total pancreatectomy, pancreaticoduodenectomy, distal pancreatectomy, pancreaticojejunostomy, enucleation, or Frey procedure). An exception to this criterion are subjects with CP who had a history of surgery (including pancreaticoduodenectomy, pancreatic ojejunostomy, distal pancreatectomy, or Frey). - Previous treatment for pancreatic cancer, including chemotherapy or radiation. - Previous vagotomy or gastric surgery, including endoscopic gastric reduction procedures. - Previous diagnosis of gastroparesis. - Patients on treatment for any cancer (except non-melanoma skin cancer or carcinoma in-situ of the cervix). - Allergy or intolerance to ingredients in Boost drink in subjects undergoing mixed meal testing
