About this study

Official title: A Multi-Center, Open-Label, Phase I Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Anti-tumor Activity of Pan-RAS Inhibitor YL-17231 in Patients With Advanced Solid Tumors Harboring Mutations in KRAS, HRAS, or NRAS

This study will evaluate the safety, tolerability, drug levels, pharmacodynamic effects, and clinical activity of YL 17231 in patients with advanced solid tumors harboring mutations in KRAS, HRAS, or NRAS.

Read the detailed description

The study is a Phase 1, multi-center, open label study in 2 parts.

Part 1 (Phase Ia):

This is a 3 + 3 design dose escalation study, to evaluate the safety and tolerability, and to determine the MTD and/or RP2D of YL-17231 treatment when administered orally QD in patients with advanced solid tumors harboring mutations in KRAS, HRAS or NRAS. Up to 9 doses cohorts are planned for the dose escalation part of the study, with the starting dose of 0.25mg QD. The actual number of dose cohorts to be explored in this study will be determined by the non-tolerable dose based on dose limiting toxicities (DLTs) in conjunction with the PK and preliminary efficacy signal data. If suggested by safety and PK findings from planned dose treatment cohorts, additional dose levels may be evaluated and dosing interval may be modified under the Safety Monitoring Committee (SMC) guidance.

In Part 1, the 3+3 trial design for the dose escalation will be used and a total of 9 dose levels starting dose of 0.25 mg OD is planned.

One cycle is 21 days. DLT observation period is one cycle. The maximum tolerated dose (MTD) is the highest dose at which ≤1 of 6 patients experiences a DLT during the DLT observation period. The study will identify a maximum tolerated dose (MTD) if possible, with safety and tolerability data. All available data, including safety, tolerability, PK, PD and preliminary anti-tumor activity from each cohort will be reviewed by the SMC to determine the RP2D.

Patients may be permitted an intra-patient dose-escalation of YL-17231 to a higher dose level that has been cleared and deemed safe by the SMC if they have completed Cycle 2 at their initial enrolled dose level and continued on-study with no treatment related ≥ Grade 2 AEs. The Investigator must consult with the Medical Monitor to confirm if the patient is permitted be dose-escalated to a dose-level already cleared by the SMC.

Backfilling Additional patients (up to total of 12) may be enrolled in the dose levels which have been cleared and deemed safe by SMC to further evaluate the safety, tolerability and PK. This is referred to as backfilling.

Part 2 (Phase Ib):

This is a dose expansion phase to further evaluate the safety, tolerability and preliminary anti-tumor activity of YL 17231 at the RP2D selected by SMC.

The number of patients to be enrolled for the expansion cohorts, the RP2D and the desired patient population will be determined by the emerging data from part 1 of the study, including safety, tolerability, PK, PD and preliminary anti-tumor efficacy, as well as any other relevant evolving clinical data, and will be clarified through a protocol amendment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Occurrence of dose limiting toxicities (DLTs)

    A toxicity will be considered dose-limiting if it occurs during the first cycle (21 days) of treatment with YL-17231.

    Measured: The first cycle (21 days)

  2. TEAEs

    AEs will be coded using Medical Dictionary for Regulatory Activities current version. AEs will be regarded as treatment-emergent AEs (TEAEs) if they occur after first treatment. The frequencies will be presented including number and percentages of patients having experienced an event and the total number of events.

    Measured: Through study completion, an average of 1 year

  3. SAEs

    Serious AEs

    Measured: Through study completion, an average of 1 year

    ORR, defined as percentage of patients with a documented CR or PR in Response Evaluation Criteria in Solid Tumors 1.1(RECIST 1.1)

    Measured: From first dose of study treatment to the first documented disease progression or death due to any cause, whichever occurs first, assessed up to 30 months.

  2. Duration of Response (DOR)

    Measured: From first documentation of a response (PR or CR) to the first documented disease progression or death due to any cause, whichever occurs first, assessed up to 30 months.

  3. Progression Free Survival (PFS)

    PFS, defined as time from first dose of study treatment to the first documented disease progression or death due to any cause, whichever occurs first.

    Measured: From first dose of study treatment to the first documented disease progression or death due to any cause, whichever occurs first, assessed up to 30 months.

  4. Disease Control Rate (DCR)

    DCR, defined as percentage of patients with a documented CR or PR and SD

    Measured: From first dose of study treatment to the first documented disease progression or death due to any cause, whichever occurs first, assessed up to 30 months.

  5. AUC(0-T)

    Area under the concentration-time curve from time zero to the last quantifiable concentration of YL-17231

    Measured: During Cycles 1 and 2 (each cycle is 21 days)

  6. Cmax

    Maximum observed serum concentration of YL-17231 is observed directly from data

    Measured: During Cycles 1 and 2 (each cycle is 21 days)

  7. T1/2

    Elimination half life of YL-17231 is observed directly from data

    Measured: During Cycles 1 and 2 (each cycle is 21 days)

  8. Tmax

    Time to maximum plasma concentration of YL-17231 is observed directly from data as time of Cmax

    Measured: During Cycles 1 and 2 (each cycle is 21 days)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing YL-17231 in people with Advanced Solid Tumors, run by Shanghai YingLi Pharmaceutical Co. Ltd. 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 13 inclusion and 19 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 9 Apr 2025. 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 David S. Hong, MD ((713) 563-1930, dshong@mdanderson.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Occurrence of dose limiting toxicities (DLTs) (time frame: The first cycle (21 days)). 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 9 Apr 2025.
