Clinical Trial Summary

This is a Phase 1, open-label study of HMPL-689 administered orally to patients with lymphoma for whom failed of standard care or have no standard of care.This study consists of a dose escalation stage (Stage I) and a dose expansion stage (Stage II).

Description:

Both Stage I and Stage II include the following periods: screening period, treatment period, safety follow-up period, and extended progression free survival (PFS) follow-up period, as defined in Dose Escalation Stage (Stage I).

Dose escalation will be performed according to a modified toxicity probability interval scheme-2 (mTPI-2).To further characterize safety and efficacy of HMPL-689 at RP2D, expansion stage of the study enrolled 144 patients with B cell lymphoma, including CLL/ SLL, FL, MZL, DLBCL, MCL and PTCL. Patients were treated with RP2D as starting dose.

8. Prior treatment with any PI3K inhibitors and discontinued due to disease progression

9. Any anti-cancer therapy, including chemotherapy, radiotherapy within 3 weeks prior to initiation of study treatment

10. G-CSF/blood transfusion is prohibited 7 days before the screening hematology test

11. Any steroid therapy or approved targeted small molecule agents for anti-neoplastic intent within 7 days or approximately 5 half-lives, whichever is the longer, prior to initiation of study treatment

12. Any monoclonal antibody for anti-neoplastic intent within 6 weeks or 2 half-lives, whichever is the longer, prior to initiation of study treatment

13. Prior use of any anti-cancer vaccine

14. Prior administration of radioimmunotherapy within 3 months prior to initiation of study treatment

15. Prior use of any drug that is a strong inducer of CYP3A4, strong inhibitor of CYP3A4 within 2 weeks prior to initiation of study treatment (refer to Appendix 13)

16. Prior autologous transplant within 6 months prior to initiation of study treatment

17. Prior allogeneic stem cell transplant within 6 months prior to initiation of study treatment or with any evidence of active graft versus host disease or requirement for immunosuppressants within 21 days prior to initiation of study treatment

18. Clinically significant active infection (e.g., pneumonia)

19. Major surgical procedure within 4 weeks prior to initiation of study treatment

21. Adverse events from prior anti-cancer therapy that have not resolved to Grade 1, except for alopecia

22. Pregnant (positive pregnancy test) or lactating women
