About this study
Official title: A Phase I/IIa Study to Evaluate the Tolerance, Safety, Pharmacokinetic Characteristics and Preliminary Efficacy of PM1022 in Patients With Advanced Tumors
This study incluces a phase I study to evaluate the tolerance, safety, pharmacokinetic characteristics and preliminary efficacy of PM1022 in patients with advanced tumors and a phase IIa study to investigate the efficacy of PM1022 in patients with advanced tumors.
Read the detailed description
PM1022 is a recombinant humanized anti-PDL1 and anti-TIGIT bispecific antibody. This Phase 1/2, multicenter, first-in-human, open-label, dose-escalation, dose expansion, and clinical expansion study will evaluate the safety, tolerability, pharmacokinetics, and preliminary anti-tumor efficacy of PM1022 administered as a single-agent by IV infusion every 3 weeks to patients with locally advanced or metastatic solid malignancies, who have failed or are intolerant to standard therapy, or for whom no standard therapy is available.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing PM1022 in people with Advanced Tumors, run by Biotheus Inc. 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 10 inclusion and 26 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: status not confirmed, as of the sponsor's last update on 22 May 2023. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Ye Guo (+86 13501678472, Pattrickguo@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Adverse events (time frame: Up to 30 days after last treatment). 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 22 May 2023; AzTrials last refreshed its copy on 7 Nov 2026.
