Clinical summary

Summary

This is an open-label dose escalation and dose expansion study. Part 1 of the study (dose escalation) consists of 6 cohorts. Each cohort will be assigned a different dose level of HP518: either 25mg/d, 50mg/d, 100mg/d, 200mg/d, 300mg/d or 400mg/d. In all cohorts, HP518 will be administered orally, once daily in 28-day cycles. In Part 2 of the study (dose expansion), participants will receive HP518 orally, once daily in 28-day cycles at the highest dosage level with acceptable toxicity (RP2D) based on the data from Part 1 of the study.
