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
- Participants with locally advanced, recurrent or metastatic histologically confirmed HNSCC, NSCLC, ESCC, CRC; locally advanced or recurrent disease must not be amenable to resection with curative intent
- Dose Escalation: Participants who have relapsed or progressed following prior anticancer therapy in the advanced/metastatic setting and for whom no approved or standard therapy is available.
- Dose Exploration and Dose Expansion: The following tumor-specific criteria also apply. These cohorts will include all or a subset of these tumors. HNSCC - Received no more than 3 prior lines of therapy in the advanced or metastatic setting NSCLC - For participants with a targetable molecular alteration: received appropriate standard targeted therapy and no more than 2 prior lines of systemic chemotherapy in the advanced/metastatic setting. For participants without a targetable molecular alteration: received platinum-based chemotherapy and CPI (in combination or separately), and have received no more than 2 prior lines of systemic chemotherapy in the advanced/metastatic setting ESCC - Received no more than 3 prior lines of therapy in the advanced/metastatic setting CRC - For participants with a targetable molecular alteration (including dMMR or MSI-H): Received appropriate standard therapy for the alteration, at least 2 prior lines of systemic chemotherapy, and no more than 4 prior lines of therapy in the advanced/metastatic setting. For participants without a targetable molecule alteration: Received at least 2 prior lines of systemic chemotherapy (including an oxaliplatin-based chemotherapy), vascular endothelial growth factor (VEGF)-based therapy, and no more than 4 prior lines of therapy in the advanced/metastatic setting.

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.
