About this study

Official title: A First-in-Human, Open-Label, Dose Escalation and Expansion Study of Orally Administered NX-019 in Patients with Advanced, EGFR Mutant Cancer

This is a 2-part, first-in-human, open-label study to determine the safety and tolerability of NX-019 and preliminary efficacy in patients with locally advanced or metastatic epidermal growth factor receptor (EGFR)-mutant cancer.

Read the detailed description

Part 1: The primary objective of Part 1 of this study is to evaluate the safety and tolerability of NX-019 and to determine the maximum tolerated dose (MTD)/Recommended Expansion Dose(s) (REDs).

Part 2: The primary objective of Part 2 of this study is to confirm the safety and tolerability of NX-019 at the REDs and, for each expansion cohort, the preliminary evidence of efficacy as measured by objective response rate (ORR).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing NX-019 in people with EGFR Mutation-Related Tumors, run by Nalo Therapeutics Inc. at 12 sites in 3 countries.

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 20 inclusion and 20 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: under way, not looking for participants, as of the sponsor's last update on 11 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in United States, South Korea, Taiwan. 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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part 1 and Part 2: Incidence of Treatment-emergent Adverse Events (TEAEs) (time frame: Up to 4.5 years). The study lists 4 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 11 Mar 2025.
