Brief summary
This study aims to assess the safety, tolerability and pharmacokinetics of HMPL-689 in healthy adult volunteers. Who is it for? You may be eligible to join this study if you are a healthy adult aged between 18 and 45 years. Study details This study is evaluating safety of a new drug known as HMPL-689, that could be used for treatment of autoimmune diseases and B-cell mediated malignancies, in healthy adults. Participants will receive a single dose of HMPL-689 or matching placebo on Day 1 of their admission into the Phase 1 unit. The planned dose levels are: 1, 2.5, 5, 10, 20, 25 and 30 mg (about 7 cohorts of 8 subjects). In each dose cohort, 8 subjects will be randomized to receive HMPL-689 (6 subjects) or placebo (2 subjects) under fed conditions with a standard meal. For the first dose cohort (1 mg), a group of 2 subjects (1 HMPL-689 and 1 placebo) will be dosed 24 hours prior to the planned dosing of the remaining 6 subjects. Decisions regarding escalation to the next dose or termination of the study will be made jointly by the principal investigator and the sponsor based on the clinical data (safety, tolerability, available PK data and clinical laboratory values) of each dose cohort. Any dose level maybe repeated or reduced if deemed appropriate by the Principal Investigator and Sponsor’s medical expert. The estimated study participation for each participant is approximately 5 weeks. Follow up and assessments performed over these 5 weeks include: a) Collection of medical history b) Alcohol breath testing c) Regular physical exams d) ECG and vital signs measurements e) Urine sample assessments for general heath, safety and testing for drugs of addiction f) Blood sample analysis for routine measurements including clinical laboratory safety testing and screening for HIV (AIDS virus), hepatitis and tuberculosis (TB) g) Semen sample analysis h) Pharmacokinetic blood sample collections to measure the amount of study drug in your blood i) Adverse events monitored throughout the treatment period j) Use of concomitant medications reviewed throughout the study
Interventions
Single oral dose of study drug (HMPL-689 or matching placebo) will be administered on Day 1 of participants' admission into the Phase 1 unit, 30 minutes after food intake (i.e., after consumption of a standard meal, approximately 240mL of water).
Escalating double-blind doses of HMPL-689 or placebo will be administered in accordance with the randomization/enrollment schedule.
The following cohorts are planned:

Escalating double-blind doses of HMPL-689 or placebo will be administered in accordance with the randomization/enrollment schedule. The following cohorts are planned: Each cohort will consist of 8 participants, randomly assigned to HMPL-689 or placebo treatment in a ratio of 3:1 (i.e. 6 participants will receive HMPL-689 and 2 will receive matching placebo). The dose and dosing regimen have been selected as 1, 2.5, 5, 10, 20, 25 and 30 mg and will be carefully selected based on data from preceding cohorts. There will be 7 cohorts as below: Cohort 1: 1 mg (0.5mg capsule*2) Cohort 2: 2.5 mg (2.5mg capsule*1) Cohort 3: 5 mg (2.5mg capsule*2) Cohort 4: 10 mg (10mg capsule*1) Cohort 5: 20 mg (10mg capsule*2) Cohort 6: 25 mg (10mg capsule*2+2.5mg capsule*2) Cohort 7: 30 mg (10mg capsule*3)
