Testing the Combination of Olaparib and Durvalumab, Cediranib and Durvalumab, Olaparib and Capivasertib, and Cediranib Alone in Recurrent or Refractory Endometrial Cancer Following the Earlier Phase of the Study That Tested Olaparib and Cediranib in Comparison to Cediranib Alone, and Olaparib Alone

Endometrial Adenocarcinoma Clinical Trial

Official title: A Randomized Phase II Study Comparing Single-Agent Olaparib, Single Agent Cediranib, and the Combinations of Cediranib/Olaparib, Olaparib/Durvalumab (MEDI4736), Cediranib/Durvalumab (MEDI4736), Olaparib/AZD5363 (Capivasertib) in Women With Recurrent, Persistent or Metastatic Endometrial Cancer.: A Platform Trial for Women With Recurrent or Persistent Endometrial Cancer

Status Active, not recruiting

Clinical Trial Summary

This phase II trial studies the effects of the combination of olaparib and durvalumab, cediranib and durvalumab, olaparib and capivasertib, and cediranib alone in treating patients with endometrial cancer that has come back (recurrent) or does not respond to treatment (refractory). Olaparib, cediranib, and capivasertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Durvalumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Testing the combinations may lower the chance of endometrial cancer growing or spreading compared to usual care.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To compare the efficacy of single-agent olaparib and the combination of olaparib and cediranib (and potentially other combination arms that may be added by subsequent amendment) versus single agent cediranib as measured by progression free survival (PFS), in patients with recurrent, persistent or metastatic endometrial cancer.

II. To compare the efficacy of the combination of olaparib and AZD5363 (capivasertib), and the combination of olaparib and durvalumab (MEDI4736), and the combination of cediranib and durvalumab (MEDI4736) versus single agent cediranib as measured by progression free survival (PFS), in patients with recurrent, persistent or metastatic endometrial cancer.

SECONDARY OBJECTIVES:

I. To compare the efficacy of single-agent olaparib and the combination of olaparib and cediranib (and potentially other combination arms that may be added by subsequent amendment) versus single-agent cediranib as measured by overall survival (OS) in patients with recurrent, persistent or metastatic endometrial cancer.

II. To compare the efficacy of the combination of olaparib and AZD5363 (capivasertib), and the combination of olaparib and durvalumab (MEDI4736), and the combination of cediranib and durvalumab (MEDI4736) versus single agent cediranib as measured by overall survival (OS), in patients with recurrent, persistent or metastatic endometrial cancer.

III. To compare the efficacy of single-agent olaparib and the combination of olaparib and cediranib (and potentially other combination arms may be added by subsequent amendment versus single-agent cediranib as measured by response rate in patients with recurrent, persistent or metastatic endometrial cancer.

IV. To compare the efficacy of the combination of olaparib and AZD5363 (capivasertib), and the combination of olaparib and durvalumab (MEDI4736), and the combination of cediranib and durvalumab (MEDI4736) versus single agent cediranib as measured by response rate in patients with recurrent, persistent or metastatic endometrial cancer.

V. To assess the safety and tolerability of single-agent cediranib, single-agent olaparib, and the combination of olaparib and cediranib (and potentially other combination arms may be added by subsequent amendment).

VI. To assess the safety and tolerability of the combination of olaparib and AZD5363 (capivasertib), and the combination of olaparib and durvalumab (MEDI4736), and the combination of cediranib and durvalumab (MEDI4736).

VII. To assess if mutations in deoxyribonucleic acid (DNA) homologous repair genes (assayed prior to all treatment and prior to the study treatment) are predictive of response to olaparib alone or in combination with cediranib. (Integrated Biomarker) VIII. To assess if markers of angiogenesis in serial plasma samples are associated with response to cediranib alone or in combination with olaparib. (Integrated Biomarker)

EXPLORTORY OBJECTIVE:

I. To compare the efficacy of the combination of olaparib and cediranib versus single agent olaparib as measured by PFS, response rate and OS, if and only if the combination is superior to the single-agent cediranib arm.

OUTLINE: Patients are randomized to 1 of 6 arms.

ARM I: Patients receive cediranib maleate orally (PO) once daily (QD). Cycles repeat every 28 days in the absence of disease progression or unaccepted toxicity. Additionally, patients undergo blood sample collection, bone marrow aspiration and biopsy, computed tomography (CT), echocardiography (Echo) or multigated acquisition scan (MUGA) on study.

ARM II (ENROLLMENT COMPLETE): Patients receive olaparib PO twice daily (BID). Cycles repeat every 28 days in the absence of disease progression or unaccepted toxicity. Additionally, patients undergo blood sample collection, bone marrow aspiration and biopsy, CT, Echo or MUGA on study.

ARM III (ENROLLMENT COMPLETE): Patients receive olaparib PO BID and cediranib maleate PO QD. Cycles repeat every 28 days in the absence of disease progression or unaccepted toxicity. Additionally, patients undergo blood sample collection, bone marrow aspiration and biopsy, CT, Echo or MUGA on study.

ARM IV: Patients receive olaparib PO BID on days 1-28 and capivasertib PO BID on days 1-4 each week. Cycles repeat every 28 days in the absence of disease progression or unaccepted toxicity. Additionally, patients undergo blood sample collection, bone marrow aspiration and biopsy, CT, Echo or MUGA on study.

ARM V: Patients receive olaparib PO BID on days 1-28 and durvalumab intravenously (IV) on day

1. Cycles repeat every 28 days in the absence of disease progression or unaccepted toxicity. Additionally, patients undergo blood sample collection, bone marrow aspiration and biopsy, CT, Echo or MUGA on study.

ARM VI: Patients receive cediranib maleate PO BID on days 1-28 and durvalumab IV on day 1. Cycles repeat every 28 days in the absence of disease progression or unaccepted toxicity. Additionally, patients undergo blood sample collection, bone marrow aspiration and biopsy, CT, Echo or MUGA on study.

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years. ;
