Can weight loss drugs help endometrial cancer patients during chemo?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age ≥ 18 years * Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 2 * Obesity (defined as BMI ≥ 30 kg/m2) OR Overweight (defined as BMI ≥ 27 kg/m2) with presence of ≥1 weight related comorbid condition OR a diagnosis of Type 2 Diabetes Mellitus with BMI ≥ 25 kg/m2 * Type 2 Diabetes Mellitus is defined as known history of Type 2 diabetes, HbA1c ≥ 6.5%, fasting blood glucose ≥126 mg/dL on 2 occasions, or random blood glucose ≥ 200 mg/dL with signs and symptoms of diabetes mellitus (weight loss, fatigue, polyuria, polydipsia, vision changes) * Patients with new diagnosis of stage I-III endometrial cancer * Completed surgery with TH/BSO with no gross residual disease * Recommended to undergo curative intent adjuvant chemotherapy at MSK with or without intravaginal radiation or external pelvic radiation. Chemotherapy regimen must include carboplatin and paclitaxel x 4-6 cycles. Cisplatin may be included at the discretion of the treating physician during concurrent standard chemoradiation. Patients may consent prior to and up to 8 weeks after the first cycle of chemotherapy. * Patients with the following histologic epithelial cell types are eligible: endometrioid adenocarcinoma, serous adenocarcinoma, carcinosarcoma, undifferentiated carcinoma/de-differentiated, clear cell adenocarcinoma, mixed epithelial carcinoma, adenocarcinoma not otherwise specified (N.O.S.), and mucinous adenocarcinoma. * 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.
