Study groups in NCT06431243
Study groupRoleWhat they receive
A0 groupExperimentalCohort A0 is for patients with locally advanced or metastatic breast cancer treated with PM. The cohort doses are escalated in the order of 11.2 mg/m2, 15.0 mg/m2, and XX mg/m2 (if the SMC assesses that there are safety risks in the monotherapy escalation starting dose group, it can be reduced to 8.4 mg/m2 or a dose determined by the SMC). In Cohort A0, subjects in the dose-escalation group all receive PM intravenous infusion on days 1, 4, 15, and 18 of each cycle, with a 28-day cycle (within the same dosing cycle, the interval between two doses is at least ≥48 h), and the maximum duration of dosing does not exceed 96 weeks.
Receives: Drug: A0/B0 group Purinostat Mesylate 11.2mg/m2; Drug: A0/B0 group Purinostat Mesylate 15mg/m2
A groupExperimentalCohort A is for patients with HR+/HER2- (hormone receptor positive/human epidermal growth factor receptor 2 negative) advanced breast cancer treated with PM in combination with fulvestrant. In Cohort A, subjects in the dose-escalation group all receive PM intravenous infusion on days 1, 4, 15, and 18 of each cycle, with a 28-day cycle (within the same dosing cycle, the interval between two doses is at least ≥48 h); fulvestrant (FS) is administered as two 5 mL injections slowly into the buttocks on days 1 and 15 of the first cycle, with one injection per buttock (1-2 minutes/5 mL), and starting from the second cycle, 500 mg (specification 5 mL: 0.25 g) is given once on the first day of each cycle (CnD1), with a 28-day cycle. Based on the results obtained in the dose-escalation phase, the necessity of the Phase IIa expansion cohort and the dosing of PM will be determined by the SMC after discussion.
Receives: Drug: A group Purinostat Mesylate 6mg/m2; Drug: A group Purinostat Mesylate 8.4mg/m2; Drug: A group Purinostat Mesylate 11.2mg/m2; Drug: A group Purinostat Mesylate 15 mg/m2
B0 groupExperimentalCohort B0 is for patients with advanced solid tumors treated with PM. The cohort doses are escalated in the order of 11.2 mg/m2, 15.0 mg/m2, and XX mg/m2 (if the SMC assesses that there are safety risks in the monotherapy escalation starting dose group, it can be reduced to 8.4 mg/m2 or a dose determined by the SMC). In Cohort B0, subjects in the dose-escalation group all receive PM intravenous infusion, with a dosing frequency of BiW (twice weekly), for continuous dosing over 2 weeks, that is, on days 1, 4, 8, and 11 of each cycle, with a 21-day cycle (within the same dosing cycle, the interval between two doses is at least ≥48 h), and the maximum duration of dosing does not exceed 96 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing A0/B0 group Purinostat Mesylate 11.2mg/m2, A0/B0 group Purinostat Mesylate 15mg/m2 and A group Purinostat Mesylate 6mg/m2 in people with Advanced Solid Tumor, run by Chengdu Zenitar Biomedical Technology Co., Ltd at 2 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 42 inclusion and 39 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 10 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 Liangkun Sun, bachelor (15885742617, liangkunsun@zenitar.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Objective remission rate (ORR) (time frame: Up to week 96). 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 NCT06431243.

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 10 Apr 2025.
