Testing the Combination of the Anti-Cancer Drugs Temozolomide and M1774 to Evaluate Their Safety and Effectiveness
What this study is about
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).
View original scientific description
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.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- 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

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
