Clinical Trial Summary

This is a Phase I, open-label, first in human study of HS269 tablet, a small molecule highly-selective RET Inhibitor. The dose-escalation study will assess the safety, tolerability, and pharmacokinetics of HS269 and determine the dose and schedule to be used in Phase II. Seventeen to thirty-six patients with advanced solid tumor may be enrolled in this study.

7. The subjects should be informed and agreed to the study before the start of the trial, and sign the written informed consent voluntarily.

Exclusion Criteria:

1. Received anti-tumor treatments within 14 days or less than 5 half-lives (whichever is longer) before the first use of the study drug

2. Received blood transfusion, erythropoietin, recombinant human thrombopoietin or colony stimulating factor and other treatments within 7 days before receiving blood system examination during the screening period.

3. Received other unmarketed clinical study drugs or treatments within 4 weeks before the first use of the study drug.

4. Major organ surgery (excluding biopsy) or significant trauma occurred within 4 weeks before the first use of the study drug;

5. Systemic administration of glucocorticoids (prednisone > 10 mg / day or equivalent dose of the same drug) or other immunosuppressants within 14 days before the first use of the study drug; except for local, eye, intra articular, nasal and inhaled corticosteroids; short-term use of glucocorticoids for preventive treatment (e.g. prevention of contrast agent allergy);

6. CYP1A2/P-gp potent inhibitors or potent inducers were used within 7 days before the first use of the study drug;

7. Resistance to selective RET inhibitors;

8. The adverse reactions of previous anti-tumor therapy have not yet recovered to CTCAE 5.0 grade evaluation = 1 (except for the toxicity without safety risk judged by researchers such as alopecia);

9. Patients with central nervous system metastasis or meningeal metastasis with clinical symptoms, or other evidence indicating that the central nervous system metastasis or meningeal metastasis has not been controlled, which is not suitable for the study.

10. Have active infection and need systemic anti infection therapy;

20. Female patients have a positive blood pregnancy test within 7 days before enrollment, or breastfeeding women;

21. The subjects were not suitable for the clinical study because of other serious systemic diseases or other reasons according to the investigator 's judgment.
