Description
Summary
This phase Ib/II trial tests the safety, side effects, best dose, and effectiveness of the combination of ipatasertib with megestrol acetate to megestrol acetate alone in patients with endometrial cancer that has come back (recurrent) or has spread to other places in the body (metastatic). Ipatasertib may stop the growth of tumor cells and may kill them by blocking some of the enzymes needed for cell growth. Megestrol acetate lowers the amount of estrogen and also blocks the use of estrogen made by the body. This may help stop the growth of tumor cells that need estrogen to grow. The combination of ipatasertib and megestrol acetate may be more effective in treating endometrial cancer than megestrol acetate alone.
Official Title
A Phase IB and Randomized Phase II Trial of Megestrol Acetate With or Without Ipatasertib in Recurrent or Metastatic Endometrioid Endometrial Cancer
Details
PRIMARY OBJECTIVES:
- Determine the toxicity of ipatasertib in combination with megestrol acetate in women with metastatic grade 1-2 endometrioid endometrial cancer and establish the recommended phase II dose. (Phase I) II. Compare the progression free survival of the combination of ipatasertib with megestrol acetate to megestrol acetate alone among women with metastatic grade 1-2 endometrioid adenocarcinoma of the endometrium. (Phase II) III. Compare the toxicity of the combination of ipatasertib with megestrol acetate to megestrol acetate alone. (Phase II)
SECONDARY OBJECTIVES:
- Compare objective response rate per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 between the two arms.
II. Examine the pharmacokinetics of ipatasertib + megestrol acetate to assess potential drug-drug interactions.
III. Assess the association between biomarkers and response to therapy.
EXPLORATORY OBJECTIVE:
- Explore whether pS6/total S6 and pPRAS40/total PRAS40 expression is impacted by the use of ipatasertib and megestrol acetate.
OUTLINE: This is a phase Ib, dose de-escalation study of ipatasertib followed by a phase II study.
PHASE Ib: Patients receive megestrol acetate orally (PO) once daily (QD) on days 1-28 and ipatasertib PO QD on days 1-21 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo a computed tomography (CT) or magnetic resonance imaging (MRI) during screening, on study, and during follow-up. Patients also undergo collection of blood samples throughout the trial.
PHASE II: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive megestrol acetate PO QD on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo a CT or MRI during screening, on study, and during follow-up. Patients also undergo collection of blood samples throughout the trial.
ARM II: Patients receive megestrol acetate PO QD on days 1-28 and ipatasertib PO QD on days 1-21 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo a CT or MRI during screening, on study, and during follow-up. Patients also undergo collection of blood samples throughout the trial.
After completion of study treatment, patients are followed up at 30 days for the phase I study. Patients are followed up every 3 months for 2 years, then every 6 months for 3 years for the phase II study.

Eligibility
You can join if…
Open to females ages 18 years and up
- Patients must have grade 1 or 2 recurrent or metastatic endometrioid endometrial cancer
- Patients must have measurable disease according to RECIST version (v)1.1. Measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded). Each lesion must be >= 10 mm when measured by CT or MRI. Lymph nodes must be >= 15 mm in short axis when measured by CT or MRI. Previously irradiated lesions can be considered as measurable disease only if progressive disease has been unequivocally documented at that site since radiation
- Patients may have received unlimited prior lines of therapy. If patient received prior hormonal therapy (e.g., megestrol acetate, medroxyprogesterone acetate, aromatase inhibitor, tamoxifen, fulvestrant) it must have completed at least 6 months prior to registration
- Age >= 18
- Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1 or 2
- Platelets >= 100,000/mcl within 14 days prior to registration
- Absolute neutrophil count (ANC) >= 1,500/mcl within 14 days prior to registration
- Hemoglobin >= 9 g/dL within 14 days prior to registration
- Glomerular filtration rate (GFR) >= 60 mL/min/1.73m2 measured using Cockcroft-Gault equation or the estimated glomerular filtration rate from the Modification of Diet in Renal Disease Study within 14 days prior to registration
- Total bilirubin =< 1.5 x the upper limit of normal (ULN) within 14 days prior to registration
- Patients with known Gilbert syndrome who have bilirubin =< 3 x ULN may be enrolled
- Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 3 x institutional ULN within 14 days prior to registration
- Albumin >= 3 g/dL within 14 days prior to registration
- Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, patients should be class 2B or better
- The effects of ipatasertib on the developing human fetus are unknown. For this reason and because AKT inhibitor agents as well as other therapeutic agents used in this trial are known to be teratogenic, participants of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) during study therapy and for 28 days following the last dose of study therapy. Should a participant become pregnant or suspect pregnancy while participating in this study, they should inform their treating physician immediately
- 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
- For patients with known human immunodeficiency virus (HIV), hepatitis B virus (HBV), and/or hepatitis C virus (HCV) infection:
- HIV-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months of registration are eligible for this trial
- Patients with evidence of chronic hepatitis B virus (HBV) infection must have an undetectable HBV viral load on suppressive therapy, if indicated
- Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load
- Patients with treated brain metastases are eligible if follow-up brain imaging after central nervous system (CNS)-directed therapy shows no evidence of progression
- Patients must be able to swallow and retain oral medications and not have gastrointestinal illnesses that would preclude absorption of megestrol acetate or ipatasertib as judged by the treating physician

- Patients who have received treatment with strong CYP3A inhibitors or inducers within 14 days or 5 drug-elimination half-lives, whichever is longer, prior to study registration
- Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
