About this study
Official title: Phase I Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetic Characteristics and Preliminary Efficacy of Injectable BL-M02D1 in Patients With Locally Advanced or Metastatic Gastrointestinal Tumors or Other Solid Tumors
In phase Ia study, the safety and tolerability of BL-M02D1 in patients with locally advanced or metastatic gastroenteric tumor or other solid tumors will be investigated to determine the dose-limiting toxicity (DLT), maximum tolerated dose (MTD) of BL-M02D1.
In phase Ib study, the safety and tolerability of BL-M02D1 at the phase Ia recommended dose will be further investigated, and recommended phase II dose (RP2D) for phase II clinical studies will be determined.
In addition, the preliminary efficacy, pharmacokinetic characteristics, and immunogenicity of BL-M02D1 in patients with locally advanced or metastatic gastroenteric tumor or other solid tumors will be evaluated.

Measured: Up to 21 days after the first dose
Phase Ia: Maximum tolerated dose (MTD)
MTD is defined as the highest dose level at which no more than 1 in 6 participants experienced a DLT during the first cycle.
Measured: Up to 21 days after the first dose
Phase Ib: Recommended Phase II Dose (RP2D)

The appearance of one or more new lesions is also considered PD]).
Measured: Up to approximately 24 months

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing BL-M02D1 in people with Locally Advanced or Metastatic Digestive Tract Tumors and Solid Tumor, run by Sichuan Baili Pharmaceutical Co., Ltd. at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 13 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 26 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Phase Ia: Dose limiting toxicity (DLT) (time frame: Up to 21 days after the first dose). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Sep 2025.
