About this study

Official title: A Phase I Dose Escalation and Cohort Expansion Study to Evaluate the Safety, Tolerance and Pharmacokinetic of BAT1308 Injection in Patients With Advanced Solid Tumors

A phase I dose escalation and cohort expansion study to evaluate the safety, tolerance and pharmacokinetic of BAT1308 injection in patients with advanced solid tumors

Read the detailed description

This study is a multicenter, open, dose-increasing and dose-expanding phase I clinical study. The dose increasing method of "3 + 3" is used to explore the safety, tolerance and pharmacokinetic characteristics of BAT1308 injection in patients with advanced solid tumors (12-18 cases). After the completion of dose increment, 300mg tolerated doses were selected for extended research on advanced non-small cell lung cancer, advanced hepatocellular carcinoma and cervical cancer (80-130 cases), so as to provide recommended doses for subsequent clinical trials.

Being tested
BAT1308

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BAT1308Drug

    A 21 day treatment cycle was administered every 3 weeks (Q3W) on day 1 of each cycle. Six consecutive dosing cycles are recommended for the dose escalation phase. In the extended study phase, after the end of the 6th treatment cycle, after the risk and benefit are evaluated by the investigator in combination with the clinical practice, if the subjects are still in a state of clinical benefit (including CR, PR and SD), the investigator can decide to appropriately extend the treatment of BAT1308. Until disease progression, unacceptable toxicity, withdrawal of informed consent, loss of follow-up, death, acceptance of new antitumor therapy, termination of treatment by investigator evaluation, or 12 months after initial administration, whichever is the earliest.

Study groups in NCT05155722
Study groupRoleWhat they receive
Single groupExperimentalFirst Phase: dose escalation study. It was divided into three dose groups: 100mg, 300mg and 600mg. The safety, tolerance and pharmacokinetics of BAT1308 injection were explored according to the 3+3 dose increasing mode. It is expected that 12-18 cases will be included in the group. Second Phase: dose expansion study. After the completion of dose increment, 300mg tolerated doses were selected for extended research on advanced non-small cell lung cancer, advanced hepatocellular carcinoma and cervical cancer (80-130 cases), so as to provide recommended doses for subsequent clinical trials.
Receives: Drug: BAT1308

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Explore the maximum tolerated dose (MTD)

    Tolerance evaluation: Dose-limiting toxicity (DLT) is defined as follows: Patients develop the following AE associated with the study drug between day 1 and day 21 after cycle 1 administration: 1)Non-hematological toxicity of grade ≥3 (nausea, vomiting, and diarrhea were relieved within 3 days after supportive treatment, except for infusion reactions that recovered within 2 hours after symptomatic treatment); 2)Grade ≥4 hematologic toxicity (including grade ≥3 neutropenia with fever; However, grade 4 neutropenia requires a duration of ≥7 days to determine DLT); 3) Grade ≥4 thrombocytopenia or grade 3 thrombocytopenia with bleeding.

    Safety evaluation indexes: Safety indicators include: vital signs, physical examination, laboratory tests, electrocardiogram, cardiac color ultrasound, adverse events (including immune-related adverse events), etc.

    Measured: 21 days after first dosing

Secondary outcomes (4)

  1. To evaluate the PK characteristics of BAT1308 injection

    Blood samples were collected from all dose groups at specific time points during treatment, and 2mL blood samples were collected at each time point to detect the concentration level of BAT1308 in serum and study the pharmacokinetic (PK) characteristics of BAT1308 injection. PK blood samples were collected from subjects before and after each dosing in cycles 1 to 6. In the first and fourth cycles, intensive sampling was carried out to study PK characteristics of steady-state studies of single administration and multiple administration, respectively.

    Measured: 126 days after first dosing

  2. To evaluate the immunogenicity of BAT1308 injection

    All subjects in the dose groups were required to collect blood samples at specific points during treatment, and 3.5ml blood samples were planned for each time point to detect antidrug antibodies in the serum. For blood samples with positive anti-drug antibodies, further testing of titers and neutralizing antibodies is required.

    Measured: 126 days after first dosing

  3. To evaluate the pharmacodynamics of BAT1308 injection

    The receptor occupancy of BAT1308 injection was studied by detecting PD-1 receptor binding on T cells in peripheral blood. Subjects in all dose groups required blood samples to be collected at specific points during treatment. Pharmacodynamic receptor occupancy studies were performed only in dose-increasing subjects. 2mL blood samples were collected at each time point, and intensive samples were collected before and at the end of the first cycle, 168h and 336h, respectively, and before the second to sixth cycle.

    Measured: 126 days after first dosing

  4. Preliminary evaluation of the anti-tumor efficacy of BAT1308 injection.

    The antitumor efficacy of BAT1308 was assessed with RECIST1.1 and iRECIST1.1 throughout the trial. Tumor imaging was performed within 28 days prior to initial dosing, and the same imaging technique was used in the same patient at the same site throughout the study period. If there are brain metastases, do head MRI. RECIST 1.1 was used as the main evaluation criterion. Tumor evaluation after dosing was performed at weeks 6 (D42±5), 12 (D84±5), and 18 (D126±5). The extended study tumor assessment was performed every 9 weeks (±7 days) after week 18 until disease progression, withdrawal of informed consent, loss of follow-up, death, acceptance of new antitumor therapy, or up to 12 months after initial administration, whichever occurred first.

    Measured: 126 days after first dosing

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BAT1308 in people with Advanced Solid Tumor, run by Bio-Thera Solutions 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 12 inclusion and 25 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: finished, as of the sponsor's last update on 8 Dec 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Explore the maximum tolerated dose (MTD) (time frame: 21 days after first dosing). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05155722.

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 8 Dec 2025.
