Plain-language summary
This phase II trial tests whether ZEN003694 (ZEN-3694) in combination with talazoparib works to shrink tumors in patients with solid tumors that are unlikely to be cured or controlled with treatment and that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Another aim of this study is to find out if, and how, patients' genes influence their response to this specific drug combination. For this part of the study, investigators will run tests using samples of patients' tumor tissue and blood that will be collected during the study. ZEN-3694 is an inhibitor of a family of proteins called the bromodomain and extra-terminal (BET). It may prevent the growth of tumor cells that overproduce BET protein. Talazoparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Genes are pieces of the DNA code that individuals inherit from their parents. Some genes work to protect against cancer by correcting damage that can occur in the DNA when cells divide. BRCA1 and BRCA2 are two examples of these types of genes, and they are called tumor-suppressor genes. For example, if a person has a mutation in a BRCA1/2 gene they have a greatly increased risk of developing breast and ovarian cancer because their cells may no longer be able to completely repair damaged DNA. It is the accumulation of DNA damage which causes a cell to change into a cancerous cell. Other genes are also involved in this process, and these are called DNA damage repair genes. The KRAS mutation is a change in a protein in normal cells. Normally KRAS serves as an information hub for signals in the cell that lead to cell growth, but when there is a mutation in KRAS it signals too much and cells grow without being told to, which causes cancer. Combination therapy with ZEN-3694 and talazoparib may be effective at slowing or stopping tumor growth in patients with advanced cancer.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Patients must have histologically confirmed malignancy that is metastatic or unresectable and for which standard curative or palliative measures do not exist or are no longer effective
* Patients must have a tumor lesion that can be biopsied with 'low' or 'minimal' risk and at least one measurable disease site, as defined by Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1
* Note: Tumor lesions that are situated in a previously irradiated area may or may not be considered measurable
* Patients in cohorts 1, 2, and 4 should have at least one relevant mutation. Patients enrolled in cohorts 1-3 do not require that PARP inhibitor (i) be the immediate prior therapy to be eligible for the trial. Patients should sign a screening consent that will allow the review of local next generation sequencing (NGS) or equivalent Clinical Laboratory Improvement Amendment (CLIA)-certified assay results by MD Anderson's Precision Oncology Decision Support (PODS) team to ensure that the mutations are actionable. No variants of uncertain significance (VUS) will be allowed
* Patients in Cohort 1 must have (i) a germline or somatic mutation in BRCA1 or BRCA2; and (ii) must have received prior PARPi monotherapy or PARPi combination-therapy
* Patients in Cohort 2 must have: (i) a germline or somatic mutation in any of the following deoxyribonucleic acid (DNA) damage response (DDR) genes: BARD1; FANCA; BRIP1; PALB2; RAD51; RAD51C; RAD51D, with no evide…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
