A Phase 1 study testing PCNA Inhibitor AOH1996 in people with Refractory Malignant Solid Neoplasm and Osteosarcoma, run by City of Hope Medical Center at 3 sites in United States.
Trial summary
This phase I trial studies the side effects and best dose of AOH1996 in treating patients with solid tumors that do not respond to treatment (refractory). AOH1996 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Read more about this study

About this study
Official title: First in Human Phase 1 Study of AOH1996 in Patients With Refractory Solid Tumors
This phase I trial studies the side effects and best dose of AOH1996 in treating patients with solid tumors that do not respond to treatment (refractory). AOH1996 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Read the detailed description
PRIMARY OBJECTIVES:
- To determine the maximum tolerated dose (MTD) and the dose limiting toxicities (DLT) of AOH1996.
II. To establish the recommended phase 2 dose of AOH1996.
III. To establish the recommended phase 2 dose of AOH1996 when given in conjunction with a TKI for NSCLC.
SECONDARY OBJECTIVES:
- To determine the pharmacokinetics of AOH1996. II. To evaluate for preliminary efficacy of AOH1996. III. To evaluate response rate and disease control rate in solid tumors.

What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of adverse events (AEs)
Toxicity and adverse events will be recorded using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. All toxicities/AEs will be recorded from the initiation of protocol therapy through the follow-up period.
Measured: Up to 30 days after last study drug is given
Dose limiting toxicities
Toxicities will be graded according to NCI CTCAE version 4.0.
Measured: Up to 28 days (cycle 1)
Secondary outcomes (4)
Response rate
Will be assessed using Response Evaluation Criteria in Solid Tumors version 1. Response rate will be estimated in the overall population and 95% exact confidence intervals will be estimated.
Measured: Up to 2 years
Progression-free survival
Time to disease progression/ relapse or death as a result of any cause.
Measured: Assessed up to 2 years
Overall survival
Time to death as a result of any cause.
Measured: Assessed up to 2 years
Time to treatment failure
Time to treatment termination for any reason (progression, toxicity, death, patient preference).
Measured: Assessed up to 2 years

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing PCNA Inhibitor AOH1996 in people with Refractory Malignant Solid Neoplasm and Osteosarcoma, run by City of Hope Medical Center at 3 sites in United States.
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 19 inclusion and 15 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 20 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in United States. 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 Vincent Chung, MD (6262184673, vchung@coh.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of adverse events (AEs) (time frame: Up to 30 days after last study drug is given). The study lists 2 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 20 Oct 2026.
