This phase I/II trial studies the side effects and best dose of temozolomide and M1774 and how well they works in treating patients with cancer that has spread from where it first started (primary site) to other places in the body (metastatic) and may have spread to nearby tissue, lymph nodes, or distant parts of the body (advanced). Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid (DNA) and may kill tumor cells and slow down or stop tumor growth. M1774 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Adding M1774 to temozolomide may shrink or stabilize cancer for longer than temozolomide alone.
Eligibility criteria
Qualifiers
Patients must have histologically or cytologically confirmed diagnosis of metastatic advanced cancer.
In dose escalation, any solid tumor patients with either O6-methylguanine DNA methyltransferase (MGMT) promoter hypermethylation positivity on testing / pre-screening of archival tissue OR an extracranial solid tumor where TMZ is considered a standard of care per National Comprehensive Cancer Network (NCCN) guidelines (neuroendocrine tumor, small cell lung cancer, melanoma or soft tissue sarcoma). The tumor lesion must be safely accessible to a mandatory biopsy. Patients with MGMT promoter hypermethylated colorectal cancer must be mismatch repair proficient / microsatellite stable.
In phase 2, only patients with mismatch repair proficient / microsatellite stable colorectal cancer that have MGMT promoter hypermethylation positivity on pre-screening of archival tissue will be eligible.
In dose escalation, patients must have progressed after treatment with all available therapies including immunotherapies for metastatic disease that are known to confer clinical benefit, or are intolerant to treatment, or refuse standard treatment. Patients may not have previously received temozolomide or an ataxia telangiectasia and rad3-related (ATR) inhibitor.
Disqualifiers
Patients who have not recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities > grade 1) with the exception of alopecia and neuropathy, which may be =< grade 2.
History of allergic reactions or hypersensitivity attributed to compounds of similar chemical or biologic composition to M1774 or temozolomide, including dacarbazine.
Patients with uncontrolled intercurrent illness.
Pregnant women are excluded from this study because M1774 is an ATR inhibiting agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with M1774 breastfeeding should be discontinued if the mother is treated with M1774. These potential risks also apply to temozolomide.
