New biologic drug CM518D1 enters human trials for advanced cancers
NCT ID NCT07019779
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new biologic drug, CM518D1, in people with advanced solid tumors that have not responded to standard treatments. The trial has two phases: first, to find the safest dose and check for side effects, and second, to see if the drug can shrink tumors. About 434 participants will receive the drug intravenously every three weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CM518D1 (a biologic drug given intravenously)
- What this could lead to
- If it works, this could point toward a new treatment option for people with advanced solid tumors that have not responded to other therapies.
- What could go wrong
- This is an early-phase trial (Phase 1/2) with a small number of participants, so the drug may not prove effective or safe enough for wider use. Side effects are unknown and will be closely monitored.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * 1\. Male or female ≥ 18 and ≤75 years of age. * 2\. Subjects with histologically or cytologically confirmed advanced solid tumors. * 3\. At least one measurable lesion according to RECIST v1.1. * 4\. Expected survival time ≥ 3 months as judged by the Investigator. Exclusion Criteria: * 1\. Subjects who have received any chemotherapy or any drug therapy for antitumor treatment including monoclonal antibodies, targeted therapy, radioimmunoconjugates, or Antibody-Drug Conjugates(ADCs), or any investigational product therapy for anti-tumor therapy within 28 days prior to the first dose or within 5 half-lives (whichever is shorter). * 2\. Subjects who have received major surgery within 28 days prior to the first dose. * 3\. Subjects who have received radiotherapy within 21 days prior to the first dose. * 4\. Subjects who have received systemic glucocorticoid therapy (more than 10 mg of prednisone or equivalent daily) or other forms of immunosuppressive therapy within 7 days prior to the first dose. * 5\. Subjects who have received any CDH17-targeted therapy. * 6\. History of other malignancies within 5 years prior to the first dose, excluding cured basal or squamous cell carcinoma of skin, carcinoma cervix in situ, or breast ductal carcinoma in situ. * 7\. Hypersensitivity to the investigational drug or its excipients. * 8\. Pregnant or lactating female patients.
