Clinical Trial Summary

This is a phase I/IIa, open-label, dose-escalation and expansion study to evaluate the safety, tolerability, PK and preliminary anti-tumor activity of H002 when given orally in patients with active EGFR mutation locally advanced or metastatic non-small cell lung cancer (NSCLC). The study will contain two parts: Part A is dose escalation phase (i.e., Phase I) and Part B is dose expansion phase (i.e., Phase IIa).

Description:

Part A (Dose Escalation Phase) Approximately 36 subjects will be enrolled, based on the "3+3" design for dose escalation and safety evaluation requirements. The total number of subjects will depend upon the number of dose escalations necessary. Part B (Dose Expansion Phase) Up to 20 subjects will be enrolled in each expansion arm, the total number of subjects will depend upon the number of dose expansions (expansions may be at more than one dose depending upon emerging data).

10. Subjects who have symptomatic brain metastases, meningeal metastasis or spinal cord compression.

11. Subjects who have a chronic or active infection that required systemic treatment within 2 weeks prior to the first dose of H002.

12. Subjects who have gastrointestinal disorders that will affect oral administration or the investigator judges that the absorption of H002 will be interfered.

13. History of hypersensitivity to active or inactive excipients of H002 or drugs with a similar chemical structure or class to H002.

14. Subjects who received a diagnosis of, and/or tested positive at screening for human immunodeficiency virus (HIV).

15. Subjects with active hepatitis B.

16. Presence or history of malignancy other than NSCLC with the exception of some certain early-stage cancers.

17. Subjects who have clinically significant cardiovascular diseases that occurred within 6 months prior to the first dose of H002, include but not limited to QTc interval = 470 msec.

18. Major surgery or significant traumatic injury occurring within 4 weeks prior to the first dose of H002 or anticipation of need for a major surgery during the study.

19. Medical history of ILD.

20. Medical history of severe eye disease without recovery to CTCAE v5.0 Grade 0 or 1.

21. Severe gastrointestinal disease within 4 weeks prior to the first dose of H002 and did not recover to = CTCAE v5.0 Grade 2.

22. Has any bleeding tendency or coagulopathy within 6 months prior to the first dose of H002.

23. Has known psychiatric disorders that would interfere with cooperation with the requirements of the trial or is still requiring for medication control.
