Study of Chemotherapy Plus Ipatasertib for People With Solid Tumors With PTEN/AKT Mutations, A ComboMATCH Treatment Trial

Paused · Phase 2

Conditions studied: Locally Advanced Malignant Solid Neoplasm, Metastatic Malignant Solid Neoplasm, Unresectable Malignant Solid Neoplasm

In brief

This phase II ComboMATCH treatment trial tests the usual treatment of chemotherapy (paclitaxel) plus ipatasertib in patients with solid tumor cancers that that cannot be removed by surgery (unresectable), has spread to nearby tissue or lymph nodes (locally advanced) or from where it first started (primary site) to other places in the body (metastatic), and has PTEN and AKT genetic changes. Chemotherapy drugs, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Targeted therapy, such as Ipatasertib, may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. The addition of ipatasertib to paclitaxel in solid tumors with PTEN and AKT genetic changes could increase the percentage of tumors that shrink as well as lengthen the time that the tumors remain stable (without progression). Researchers hope to learn if paclitaxel plus ipatasertib will shrink this type of cancer or stop its growth.

You may qualify if…

• Patient must have enrolled onto EAY191 and must have been given a treatment assignment to ComboMATCH to EAY191-S3 based on the presence of an actionable mutation as defined in EAY191
• GENERAL COMBOMATCH EAY191 REGISTRATION INCLUSION CRITERIA:
• Participants must be enrolled on the ComboMATCH Master Registration Trial EAY191
• Participants must have an activating AKT mutation (a known mutation in AKT1, AKT2, or AKT3, a single nucleotide variant, insertion, or deletion), PTEN mutation (a known mutation in PTEN, a single nucleotide variant, insertion, or deletion), or genomic deletion loss of PTEN as determined by the ComboMATCH screening assessment
• GENERAL COMBOMATCH EAY191 REGISTRATION EXCLUSION CRITERIA:
• Participants must not have an activating KRAS, NRAS, HRAS, or BRAF mutation (a single nucleotide variant, insertion, or deletion) as determined by the ComboMATCH screening assessment
• Participants must have disease that can be safely biopsied and agree to a pre-treatment biopsy or have archival tissue available from within 12 months prior to the date of registration on the ComboMATCH Registration Trial (EAY191)
• Participants must have a histologically confirmed non-breast solid malignancy
• Participants must have locally advanced, unresectable, or metastatic disease in the opinion of the treating investigator
• Participants must have measurable disease documented by CT or MRI. Measurable disease must be assessed within 28 days prior to registration. Non-measurable disease must be assessed within 42 days prior to registration. The CT from a combined positron emission tomography (PET)/CT may be used only if it is of diagnostic quality. All known sites of disease must be assessed and documented on the Baseline Tumor Assessment Form (Response Evaluation Criteria in Solid Tumors [RECIST] 1.1). Participants whose only measurable disease is within a previous radiation therapy port must demonstrate clearly progressive disease (in the opinion of the treating investigator) prior to registration
• Participants with known brain metastases must have a CT/MRI scan to evaluate for central nervous system (CNS) disease and show no evidence of progression within 42 days prior to registration
• Participants must have completed any CNS-directed therapy and/or local therapy for spinal cord compression at least 28 days prior to registration
• Participants must not have spinal cord compression or brain metastases unless: (1) metastases have been locally treated and have remained clinically controlled and asymptomatic for at least 14 days prior to registration, AND (2) participant has no residual neurological dysfunction and has been off corticosteroids for at least 24 hours prior to registration
• Participants must not have leptomeningeal disease
• Participants must have progressed on or within 6 months of taxane-based therapy in the neoadjuvant/adjuvant or metastatic setting prior to registration
• Participants must not have received any prior AKT inhibitor (e.g., capivasertib or ipatasertib); prior PI3K/mTOR inhibitor is acceptable
• Participants must not have received cancer-directed therapy prior for at least 14 days prior to initiation of treatment on study
• Participants must not be planning to receive any concurrent chemotherapy, immunotherapy, biologic, radiation, or hormonal therapy for cancer treatment while receiving treatment on this study
• Participants must be >= 18 years of age
• Participants must be able to swallow oral medications whole
• Participants must have a pre-study history and physical exam done within 28 days prior to registration
• Participants must have a Zubrod performance status of 0-2 within 28 days prior to registration
• Participants must have adverse events resolved =< grade 1 related to any prior therapy, except alopecia within 14 days prior to registration
• Participants with neuropathy must have resolved to < grade 2 within 14 days prior to registration
• Leukocytes >= 3 x 10\^3/uL (within 28 days prior to registration)
