Study Overview

A Study of YL-17231 in Patients With Advanced Solid Tumors

This is a phase 1 open label multicenter study to evaluate the maximum tolerance, safety, tolerance and PK of oral YL-17231 in patients with advanced solid tumors with KRAS mutation, so as to confirm the recommended phase 2 dose of YL-17231 and obtain the preliminary efficacy information of patients with advanced solid tumors with KRAS mutation.

The study will be conducted in China to provide safety, efficacy and PK data. A dose escalation part 1 will be conducted to determine the MTD, DLTs, and part 2 will confirm the safety/tolerability of the recommended Phase 2 dose (RP2D), of YL-17231 given twice daily, in patients with advanced solid tumors to obtain preliminary efficacy information. PK samplings at single dose stage Day 1 and at steady-state conditions (Cycle 1, Day 14) will be performed.

Arms and Interventions

Participant Group/ArmIntervention/Treatment
EXPERIMENTAL: YL-17231

YL-17231 will be administrated orally from 0.25mg QD, 0.5mg BID to 10mg BID in sequence during dose excalation part and selected doses in dose expansion part,for 21 consecutive days as a treatment cycle

DRUG: YL-17231

  • After a screening period of approximately 14 days, eligible patients will receive oral YL-17231 once or twice daily until documented disease progression, unacceptable AEs, intercurrent illness preventing further administrations of study treatment, investi
Primary Outcome MeasuresMeasure DescriptionTime Frame
DLTsDose limited toxicitiesAt the end of Cycle 1 (each cycle is 21 days)
TEAEsTreatment emergent adverse eventsFrom day 1 after taking the investigational product till 30 days after withdrawal from the study
Secondary Outcome MeasuresMeasure DescriptionTime Frame
CmaxPeak plasma concentrationFrom day 1 to the end of Cycle 2 (each cycle is 21 days)
AUCArea under the plasma concentration versus time curveFrom day 1 to the end of Cycle 2 (each cycle is 21 days)
TmaxTime to maximum plasma concentrationFrom day 1 to the end of Cycle 2 (each cycle is 21 days)
T1/2Elimination half-lifeFrom day 1 to the end of Cycle 2 (each cycle is 21 days)
The overall response rate (ORR)The overall response rate (ORR) will be estimated based on the proportion of evaluable patients whose overall response (ORR) during study treatment is CR or PR. Disease response will be assessed by the investigator using RECIST v1.1From date of screening until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 36 months
DORDuration of responseFrom date of screening until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 36 months
Disease control rate, DCRThe percentage of cases with remission (PR+CR) and stable lesions (SD) after treatmentFrom date of screening until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 36 months
Progression free survival, PFSPFS, defined as the time from the first dose of study treatment to first documented progressionFrom date of screening until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 36 months
Overall survival, OSThe time from randomization to death for any reasonFrom date of screening until the date of death from any cause, assessed up to 36 months

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person’s general health condition or prior treatments.

Ages Eligible for Study:
ALL

Sexes Eligible for Study:
18 Years

Accepts Healthy Volunteers:

    Inclusion Criteria:
    The patients must meet all the following inclusion criteria to be eligible for enrollment in this trial:
    1. Age between 18 and 75 years (inclusive), with no gender restriction. 2. Locally advanced or metastatic solid tumors diagnosed histologically and genomically confirmed with KRAS mutation, excluding patients with a clear KRAS wild-type test report in the case of pancreatic cancer.
    A. For patients with NSCLC, previous treatment failure based on platinum-based first-line therapy; B. For patients with colorectal cancer, previous experience with at least two lines of systemic therapy (patients with colorectal cancer and high microsatellite instability should have received PD-1 or PD-L1 therapy if clinically applicable); C. For patients with solid tumors other than NSCLC or colorectal cancer, at least one prior systemic treatment is required. 3. In the dose escalation phase, measurable or non-measurable tumor lesions are acceptable based on RECIST1.1 criteria; in the dose expansion phase, at least one measurable tumor lesion is required. 4. ECOG performance status (PS) of 0-1. 5. Estimated life expectancy of ≥3 months. 6. Good organ function levels:

  • Absolute neutrophil count (ANC) ≥1.5×109/L;
  • Platelet count (PLT) ≥100×109/L;
  • Hemoglobin (Hb) ≥90g/L (no blood transfusion within 14 days before screening);
  • Total bilirubin (TBIL) ≤1.5 times the upper limit of normal;
