Testando a adição do inibidor de AKT, Ipatasertib, ao tratamento com o agente hormonal acetato de megestrol para câncer endometrial recorrente ou metastático

30 de setembro de 2026 atualizado por: National Cancer Institute (NCI)

Um estudo randomizado de Fase IB e Fase II de acetato de megestrol com ou sem ipatasertibe em câncer de endométrio endometrióide metastático ou recorrente

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.

Descrição detalhada

PRIMARY OBJECTIVES:

I. 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:

I. 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:

I. 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.

Descrição

Inclusion Criteria:

  • 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/1.73m^2 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

  • The patient or a legally authorized representative must provide study-specific informed consent prior to study entry and, for patients treated in the United States (U.S.), authorization permitting release of personal health information

O que o estudo está medindo?

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Incidence of adverse events (AEs) (Phase Ib)
Prazo: Up to 5 years

To determine frequency and severity of adverse events for all dose combinations of megestrol acetate plus ipatasertib. Descriptive statistics will be used to summarize AEs. These analyses will focus on individuals who initiated their assigned treatment and will summarize maximum grade of AEs occurring during treatment classified by Common Toxicity Criteria (CTC) category. The primary summary of AEs will present counts and percentages, regardless of whether the AE was attributed to any of the study agents.
Up to 5 years
Maximum tolerated dose for phase II (Phase Ib)
Prazo: Up to 5 years

Descriptive statistics will be used to summarize AEs. These analyses will focus on individuals who initiated their assigned treatment and will summarize maximum grade of AEs occurring during treatment classified by CTC category. The primary summary of AEs will present counts and percentages, regardless of whether the AE was attributed to any of the study agents.
Up to 5 years
Progression free survival (PFS) (Phase II)
Prazo: From study entry to time of progression or death, whichever occurs first, or date of last contact if neither progression nor death has occurred, assessed up to 5 years

Compare PFS of the combination of ipatasertib with megestrol acetate to megestrol acetate alone among women with recurrent/metastatic endometrioid adenocarcinoma of the endometrium. A product-limit method will be used to estimate the cumulative distribution of PFS duration for each of the study treatments used in this population.
From study entry to time of progression or death, whichever occurs first, or date of last contact if neither progression nor death has occurred, assessed up to 5 years
Incidence of AEs (Phase II)
Prazo: Up to 5 years

Summarize the toxicity/adverse events of the combination of ipatasertib with megestrol acetate and megestrol acetate alone. Adverse events will be categorized using Common Terminology Criteria for Adverse Events version 5.0.
Up to 5 years

Medidas de resultados secundários

Medida de resultado
Descrição da medida
Prazo
Pharmacokinetics of ipatasertib + megestrol acetate (Phase Ib)
Prazo: On cycle 1, day 8

Examine the pharmacokinetics of ipatasertib + megestrol acetate to assess potential drug-drug interactions. This data will be summarized descriptively.
On cycle 1, day 8
Objective response rate (Phase II)
Prazo: Up to 5 years

Response is defined as complete response or partial response (CR+PR) evaluated by Response Evaluation Criteria in Solid Tumors version 1.1. A logistic model will be used to estimate the relative odds of responding (CR+PR) to megestrol acetate + ipatasertib relative to megestrol acetate alone after adjusting for prior progesterone therapy.
Up to 5 years
Biomarkers (Phase II)
Prazo: Up to 5 years

The association between biomarkers and response to therapy will be assessed. Integrated biomarker endpoints include: PTEN immunohistochemistry, estrogen receptor and progesterone receptor, whole exome sequencing, ribonucleic acid sequencing. Proportional hazards models will be used to examine the prognostic association of integrated biomarkers with PFS; and interactions between markers and treatment arm will be used to examine the markers' predictive association with PFS.
Up to 5 years
