About this study

Official title: A First-in-Human Phase 1 Dose Escalation Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of FID-022 as Monotherapy in Patients With Advanced Solid Tumors

The goal of this Phase I Clinical Trial is to evaluate the safety and tolerability of FID-022 in patients with advanced solid tumors.

Read the detailed description

FID-022-001 is a Phase 1, multicenter, open label dose escalation clinical study of FID-022 as monotherapy. FID-022 is composed of topoisomerase inhibitors encapsulated with a polyethyloxazoline material. The study drug is administered through intravenous route. Patients with advanced solid tumor diagnosis without standard curative treatments are the target population (please see the eligibility section)

Being tested
FID-022

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • FID-022Drug

    FID-022 is composed of SN38 and irinotecan (a prodrug of SN38) that are encapsulated with a polyethyloxazoline (PEOX) material.

    Measured: Through study completion, approximately 2.5 years

  8. Tumor Response Assessment: Time to Response (TTR)

    TTR is defined as the time from the initial dosing to the date of first documented response to the treatment, e.g. complete response or partial response, assessed by investigator and based on RECIST v. 1.1.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing FID-022 in people with Advanced Solid Tumors, run by Fulgent Pharma LLC. 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 24 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 8 Sep 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 Fulgent Pharma (626-434-8896, info@fulgentpharma.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

MTD determination (time frame: Through study completion, approximately 2.5 years). The study lists 3 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 8 Sep 2026.
