What this trial studies

This study investigates the feasibility of using tirzepatide and semaglutide for weight management and blood sugar control in patients with endometrial cancer undergoing chemotherapy. Researchers will assess participants' experiences with the drugs, their safety during chemotherapy, and monitor changes in weight, body fat composition, and blood pressure. The study aims to provide insights into how these medications can support cancer treatment and improve patient outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a diagnosis of stage I-III endometrial cancer who are obese or overweight and are recommended for chemotherapy.

Not a fit: Patients who are not diagnosed with endometrial cancer or do not meet the obesity or overweight criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could help improve weight management and metabolic health in endometrial cancer patients, potentially enhancing their treatment outcomes.

How similar studies have performed: While the use of tirzepatide and semaglutide has shown promise in other populations, this specific application in endometrial cancer patients is novel and has not been extensively tested.

* Patient has adequate organ function, as defined by the following laboratory values:

  1. Creatinine clearance (per Cockcroft-Gault formula) ≥30 mL/min Creatinine clearance (mL/min) = ((140-age)\*wt) \* 0.85 for female/(creatinine\*72)
  2. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤3.0 × ULN.
  3. Total serum bilirubin ≤ 1.5 × ULN except for patients with Gilbert's syndrome who may be included if the total serum bilirubin is ≤3.0 × ULN or direct bilirubin ≤ 1.5 × ULN.
* Insurance approval for tirzepatide or semaglutide (alternative) or willingness to pay out-of-pocket for tirzepatide or semaglutide (alternative) for duration of study period
* Patients must be capable and willing to learn how to self-inject study drug, as required for this protocol (visually impaired persons who are not able to perform the injections must have the assistance of a sighted individual trained to inject study drug; persons with physical limitations who are not able to perform the injections must have the assistance of an individual trained to inject study drug) and administer study drug injection (or receive an injection from a trained individual if visually impaired or with physical limitations)
* Not pregnant and not nursing
* English speaking or a family member or caregiver who speaks English and is able to assist with smart phone or tablet based Keenoa app or paper dietary recall handout (if no access to smart phone or tablet).

Exclusion Criteria:

* Known Type 1 diabetes
* Known GAD, Islet Cell, or Zn Transporter 8 antibodies
* History of gastroparesis
* High risk for aspiration
* Active or history of chronic or acute pancreatitis
* History of elevated calcitonin
* Personal or family history of Medullary Thyroid Carcinoma with Multiple Endocrine Neoplasia-2 syndrome
* Patients with a prior surgical, endoscopic, and/or device-based therapy (for example, mucosal ablation, gastric artery embolization, intragastric balloon and duodenojejunal bypass sleeve) for obesity within the past two years
* Patients with removal of device-based therapy for obesity within the last 6 months
* Current GIP/GLP-1 or GLP-1 receptor agonist use or prior intolerance of GIP/GLP-1 or GLP-1 receptor agonist
* Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial.
* Known intolerance to study drug(s) or any of the excipients.
