What is being measured

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

  1. Dose escalation:Dose -limiting toxicity (DLT)

    Measured: At the end of Cycle 1 (each cycle is 21/28days)

  2. Dose escalation:Safety and Tolerability

    Safety and tolerability: Incidence and severity of AEs and serious adverse events (SAEs) assessed by CTCAE v5.0, changes in laboratory values, vital signs, and ECGs. AE related dose interruptions, dose reduction and treatment discontinuation, dose intensity

    Measured: 2 years

  3. Dose escalation: Objective response rate(ORR)

    Proportion of subjects who have a complete or partial response assessed by investigator per RECIST 1.1

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing SIM0609 for injection, dose expansion of SIM0609 in CRC and dose expansion of SIM0609 in GC/GEJC cohort in people with Advanced Solid Cancer, run by Jiangsu Simcere Pharmaceutical Co., Ltd. at 6 sites 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 9 inclusion and 28 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: looking for participants now, as of the sponsor's last update on 5 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 6 sites 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?

Contact Jinxiu Zhang (86-010-65212241, zhangjinxiu@zaiming.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Dose escalation:Dose -limiting toxicity (DLT) (time frame: At the end of Cycle 1 (each cycle is 21/28days)). 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 5 Dec 2025.
