About this study

Official title: A Phase I Clinical Study on the Safety and Efficacy of Intratumoral Administration of IDOV-SAFETM in the Treatment of Advanced Solid Tumors

This is an open-label, dose escalation, phase I study to evaluate safety tolerability, MTD, pharmacokinetic profile, immunogenicity, and pharmacodynamic profile of intratumoral Administration of IDOV-SAFETM in patients with advanced solid tumors.

Read the detailed description

The therapeutic dose for mice was 1x10^8 PFU, and the maximum starting dose for humans was 2.67x10^9 PFU based on the Guidelines for Estimating the Maximum Recommended Starting Dose for the First Clinical Trial of Healthy Adult Volunteers.

Dose escalation phase:

At this stage, the investigators plan to enroll about 13-25 patients with advanced malignant solid tumors confirmed by histology or cytology after failure of standard treatment or without standard treatment in China for intratumoral injection of IDOV-SAFETM.

This phase consisted of five dose groups: 1x10^8 PFU, 3x10^8 PFU, 7x10^8 PFU, 1x10^9 PFU and 3x10^9 PFU. The first dose group included 1 subject, and the other dose groups were increased by "3+3", with 3-6 subjects in each group. Each patient received intratumoral injection on the first day, 14 days as a course of treatment. The follow-up investigator decided whether to continue the second (D14) and third (D28) course of administration according to the comprehensive assessment of the subjects' conditions; All subjects in each dose group may be incremented to the next dose group after completing a safety assessment 21 days after the first dose.

The dose escalation or setting may be adjusted as determined by the Safety Committee (SMC).

Dose expansion phase:

According to the results of the phase I trial, one dose was selected for dose expansion, and the selected dose level was extended to 5~18 patients. Each patient received intratumoral injection on the first day, and 14 days was a course of treatment. The subsequent investigators decided whether to continue the administration of the second (D14) and third (D28) courses according to the comprehensive evaluation of the subjects' conditions. Each patient was treated for at least one course of treatment (14 days).

Based on the preliminary clinical trial data, the number of injections and the interval time of administration can be adjusted during the dose expansion phase after the decision of the Safety Committee (SMC).

Duration of administration:

In both phases, safety and efficacy were evaluated 42 days after initial dosing. If CT evaluation suspects false progression, puncture and pathology examination are required.

After SMC's decision, it is determined that the benefits of continued treatment outweigh the risks of the subject, and if the subject wishes to continue treatment, the subject may continue to receive the experimental drug. The specific course of treatment will be determined by the SMC based on preliminary clinical trial data.

The safety and efficacy of the investigational drug will be evaluated periodically during continued dosing, and the risk and benefit of continuing treatment will be determined by the SMC. If benefit > risk is no longer satisfied, the long-term safety and survival follow-up period is entered.

Long-term safety and survival follow-up:

Adverse events occurring throughout the study from the first dosing of each subject in both phases will be collected, and long-term safety and survival follow-up will continue up to 2 years after the last dosing (site visits every 8 weeks from the DLT observation period until patients meet end-of-treatment criteria or the end of survival follow-up date, whichever arrives first).

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing IDOV-SAFETM in people with Advanced Malignant Solid Tumor, run by Fudan University.

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 11 inclusion and 11 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 6 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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 Jianhua Chen, PhD (17321168230, jianhuachen15@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Dose Limiting Toxicities (DLT) (time frame: up to 3 weeks). 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 6 Feb 2025.
