Clinical Trial Summary

The primary objective of this study is to evaluate the safety and tolerability of TY-9591, with dose-escalation stage and dose-expansion stage.

Description:

• To define the maximum tolerated dose(MTD) and the recommended phase 2 dose (RP2D)

• To investigate the pharmacokinetic profile of TY-9591 and its metabolites after single then multiple doses of TY-9591 administered orally once daily

• To evaluate the anti-cancer activity of TY-9591 in NSCLC patients with EGFR mutation(ORR、PFS、DoR、DCR、and CBR)

1. Treatment with an EGFR TKI within 14 days or about 5x half-life, whichever is the longer, of the first dose of study drug;

2. Any cytotoxic chemotherapy, investigational agents or anticancer drugs for the treatment from a previous treatment regimen within 4 weeks of the first dose of study treatment;

3. Major surgery within 4 weeks of the first dose of study treatment;

4. Radiotherapy with a limited field of radiation within 1 week of the first dose of study treatment, with the exception of patients receiving radiation to more than 30% of the bone marrow or with a wide field of radiation that had to be completed within 4 weeks of the first dose of study treatment;

5. Previously treated by other third-generation epidermal growth factor receptor tyrosine kinase inhibitor(EGFR-TKI) for T790M (for example Osimertinib).

6. Patients currently receiving (or at least within 1 week prior to receiving the first dose )medications or herbal supplements known to be potent inhibitors or inducers of cytochrome P450 isoenzyme (CYP)3A4.

2. Any unresolved toxicities from prior therapy greater than Common Terminology Criteria for Adverse Events (CTCAE) grade 1 at the time of starting study treatment with the exception of alopecia and grade 2, prior platinum-therapy related neuropathy.

3. Spinal cord compression or brain metastases unless asymptomatic.

4. Dysphagia, or active digestive system diseases or previous significant bowel resection or medical conditions potentially affect TY-9591 absorption.

5. Cardiac function and disease are consistent with the following:

1. Corrected QT interval(QTc)> 470 milliseconds from 3 electrocardiograms (ECGs);

2. Any clinically important abnormalities in rhythm;

3. Any factors that increase the risk of QTc prolongation;

4. Left ventricular ejection fraction (LVEF) <50%;

6. Active human immunodeficiency virus (HIV), syphilis, hepatitis c virus (HCV) or hepatitis b virus (HBV) infection, with the exception of asymptomatic chronic hepatitis b or hepatitis c carriers.

7 .Previous history of interstitial lung disease(ILD)?drug-induced ILD or radiation pneumonitis require steroid treatment, or any evidence of clinically active ILD diseases.

8. Previous allogeneic bone marrow transplant. 9. Hypersensitivity to TY-9591 or similar compounds or excipients. 10.Pregnant or lactating women.
