New drug combo shows promise for Tough-to-Treat endometrial cancer
NCT ID NCT06463028
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new combination of drugs (sapanisertib and serabelisib, together called PIKTOR) plus standard chemotherapy (paclitaxel) in people with advanced or recurrent endometrial cancer that has not been cured by prior treatments. The goal is to see if this combo can shrink tumors or slow the cancer. A small part of the study also looks at whether a special low-insulin diet can help the drugs work better. About 40 adults will take part.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Histologically confirmed diagnosis of endometrioid endometrial carcinoma. * Documented evidence of advanced or recurrent endometrial cancer that is not amenable to surgery/radiation for curative intent. * Participant has received at least 1 but not more than 4 prior systemic therapies. Prior therapy must include platinum-based chemotherapy and a checkpoint inhibitor, either separately or in combination. If a subject has been unable to be treated with checkpoint inhibitor in the past due to medical contraindications, consult with Medical Monitor. * PI3K/AKT/mTOR pathway gene alteration identified. * At least 1 measurable target lesion according to RECIST v1.1 * Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 1 at Screening. * Non-pregnant, non-lactating females who are postmenopausal, surgically sterile or who agree to use effective contraceptive methods.. Exclusion Criteria: * Participants with central nervous system metastases are not eligible, unless they have completed local therapy and have discontinued the use of corticosteroids for this indication for at least 4 weeks before starting treatment in this study * Active malignancy (except for endometrial cancer, definitively treated in-situ carcinomas \[e.g., breast, cervix, bladder\], or basal or squamous cell carcinoma of the skin) within the past 24 months prior to treatment. Fully resected localized malignancies are eligible. * Gastric feeding tube (gastrostomy tube), gastrointestinal malabsorption, gastrointestinal anastomosis, bowel obstruction, or any other condition that might affect the absorption of study treatment. * Clinically significant (per Investigator judgement) hemoptysis or tumor bleeding. * Significant cardiovascular impairment. * Active, uncontrolled (requiring systemic antimicrobial therapy) infection. * Concurrent participation in another therapeutic clinical trial. * Prior radiation therapy within 21 days prior to start of study treatment. * Strong CYP3A4 inhibitors and inducers are prohibited during the study. Strong CYP1A2 inhibitors as well as CYP1A2 inducers should be administered with caution and at the discretion of the Investigator. Alternative treatments, if available, should be considered. Additionally, strong CYP3A4 inhibitors or inducers should not be taken within 7 days before the first dose of study intervention. * Participants who require PPIs or chronic use of antacids, histamine H2 receptor blockers, or other treatments to raise gastric pH. * Prolongation of QTc interval to \>480 ms. * HbA1c ≥ 8.0% or fasting serum glucose \> 160 mg/dL or fasting triglycerides \> 300 mg/dL or receiving treatment with insulin.
