A Study of D3L-001 as Monotherapy in Subjects With HER2-Positive Advanced Solid Tumors
What this study is about
This first-in-human (FIH) study, multi-center, where both patients and doctors know the treatment given, gradually increasing doses and dose expansion Phase I study to evaluate the safety, tolerability, how the drug moves through the body (PK), how the drug affects the body (PD), immunogenicity, and preliminary anti-tumor activity of D3L-001 in subjects with HER2-positive advanced solid tumors.
View original scientific description
This first-in-human (FIH) study, multi-center, open-label, dose escalation and dose expansion Phase I study to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), immunogenicity, and preliminary anti-tumor activity of D3L-001 in subjects with HER2-positive 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
- Subject must have documented HER2 positivity (determined by immunohistochemistry \[IHC\], in situ hybridization \[ISH\], Next Generation Sequencing \[NGS\] or other analysis techniques as appropriate).
- Subject must have Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
- Subject must have left ventricular ejection fraction (LVEF) ≥50% by either echocardiography (ECHO) or multiple-gated acquisition (MUGA) within the screening period.
- Subject must have adequate organ and marrow function within the screening period.
Exclusion criteria
- Subject has any prior treatment with anti-CD47 or SIRPα agent.
- Subject has any prior treatment without adequate washout periods as defined in the protocol.
- Subject has immunosuppressive medication that is not completed 14 days before the first dose of study medication.
- Subject has uncontrolled intercurrent illness that would limit compliance with study requirements, substantially increase risk of incurring AEs, or compromise the ability of the subject to give written informed consent.
- Subject has unresolved treatment-related toxicities from previous anticancer therapy of NCI CTCAE Grade ≥2 (with exception of vitiligo or alopecia).
- Judgment by the Investigator that the subject should not participate in the study if the subject is unlikely to comply with study procedures, restrictions, and requirements.

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.
