About this study

Official title: An Open-Label, Multi-Center Phase I Clinical Trial to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of SYH2095 in Advanced Malignant Tumors

This is an open-label, multicenter Phase 1 first-in-human trial of SYH2095, a selective KAT6A/B inhibitor. The trail contains two segments: Part 1A dose escalation and Part 2A cohort expansion. Part 1A uses the BOIN dose-escalation design, enrolling patients with advanced malignant tumors with no effective standard treatment. Its primary goals are to assess safety and tolerability, define dose-limiting toxicity (DLT) and maximum tolerated dose (MTD), and establish the recommended expansion dose (RDE). Part 2A is an expansion cohort using the RDE identified in Part 1A,. All participants receive oral SYH2095 once daily in 4-week treatment cycles. Safety evaluations, tumor imaging, pharmacokinetic (PK), pharmacodynamic (PD) and biomarker analyses will be performed at scheduled time points throughout treatment.

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 10 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: opening soon, as of the sponsor's last update on 9 Jul 2026. 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.

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 Clinical Trial Information Team Officer (+86-311 6908 5587, ctr-contact@cspc.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Dose-Limiting Toxicity (time frame: End of Part 1 Dose Escalation and Backfill phase (each cycle is 28 days; all safety data collected through Day 28 of Cycle 1 for every dose-escalation subject)]). The study lists 7 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 9 Jul 2026.
