Study of DT-7012 as a Single Agent and in Combination With an Immune Checkpoint Inhibitor in Participants With Advanced Solid Tumors
(DOMISOL)
What this study is about
This is a phase 1/2, gradually increasing doses, clinical study to evaluate the safety, tolerability, how the drug moves through the body, how the drug affects the body and effectiveness of DT-7012 (an anti-CCR8 monoclonal antibody) as a single agent and in combination with an immune checkpoint inhibitor in adult participants with selected advanced solid tumors.

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
- Histologically or cytologically confirmed solid tumor, among selected cancer types, that is recurrent, locally advanced (i.e., not eligible for curative surgery or radiotherapy) or metastatic, has progressed after at least one line of systemic therapy and has no established curative option.
- Measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 as assessed by the local site investigator/radiologist.
- At least 1 tumour lesion accessible to biopsy per treating physician judgement.
- Eastern Cooperative Oncology Group (ECOG) PS of 0 or 1.
- Adequate organ function.
Exclusion criteria
- Any unresolved AEs from previous anti-cancer therapies of grade ≥2, with the exception of alopecia.
- Prior severe immune-related AEs (irAEs) leading to immunotherapy treatment discontinuation.
- Major surgery or significant traumatic injury within 4 weeks prior to Cycle 1 Day 1 with unadequately recovered AEs and/or complications from the intervention prior to Cycle 1 Day 1.
- Prior radiotherapy within the 4 weeks prior to Cycle 1 Day 1 or limited field palliative radiotherapy within 2 weeks prior to Cycle 1 Day 1.
- Prior anti-CCR8 monoclonal antibody treatment received in an investigational trial

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.
