Description of intervention(s) / exposure
A total of 28 healthy volunteers (18 active and 10 placebo) are planned for three treatment groups and will receive a single oral dose of ACH-0145548 or placebo.
The first dose group (Cohort 1) will have 12 subjects randomized to ratio of 1:1 to active and placebo (6 active: 6 placebo), the remaining dose groups (Cohort 2 and 3) will have 8 subjects per cohort randomized 3:1 to active and placebo (6 active and 2 placebo).
For each cohort, a sentinel group consisting of one active and one placebo subject will be dosed 24 hours before the remaining subjects. If no significant drug related toxicity is identified in the first 24 hours, then remainder of each cohort may be dosed. All dose escalation decisions will be made based on the review of data through Day 4 from the preceding dose.
Safety will be evaluated by monitoring and assessing AEs, clinical laboratory tests, physical examination findings, vital signs measurements, and 12-lead ECG recordings at specified time points during the study.
The starting minimum dose of ACH-0145548 will be 20 mg for Cohort 1, 60 mg for Cohort 2, and 120 or 180 mg for Cohort 3. The maximum dose will be 180 mg. All dose escalation decisions will be made based on the review of data through at least Day 4 from the preceding dose.
The mode of administration will be Powder in Capsule (PIC) taken orally. Subjects will take their dose at the study site under direct observation by trained study personnel.

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Study drug components will be shipped to the study center in open-label fashion. An unblinded pharmacist and the associated pharmacy staff will be responsible for dispensing according to the randomisation schedule provided. The unblinded pharmacy staff will affix a blinded, unit-dose label to the drug identifying which study subject should receive which dose. All doses will be administered by blinded site staff.
Query!
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A randomization schedule, using a randomized block design, will be generated by Statistical Analysis System (SAS) software procedure Plan which assigns subjects to active versus placebo treatment for each cohort, including the 2 sentinel subjects for each cohort. The randomization schedule will then be loaded into the electronic data capturing (EDC) system which is utilized to create the study database. An unblinded pharmacist (or other qualified individual) at the study site(s) who is responsible for preparing the
study drugs to be dispensed for each subject will enter the appropriate subject’s information to the EDC system and obtain the treatment assignment of either active drug or placebo.

Statistical methods / analysis
Due to the exploratory nature of this first in human study, no power or sample size calculations have been performed. The number of subjects was chosen on an empirical basis, based on experience with other Phase 1 first-in-human studies.
There are 3 analysis populations for this study: Safety Population, Pharmacokinetic Population, and Pharmacodynamic Population.
The safety population is defined as all subjects randomized and treated with at least 1 dose of ACH-0145548 or placebo. All safety data collected up to the end of the study are included in the safety analysis. Subjects not treated according to the randomization schedule will be analyzed according to the treatment received rather than the randomized treatment.
The Pharmacokinetic (PK) population will include all subjects treated with ACH-0145548 and for whom PK parameters can be calculated.
The Pharmacodynamic (PD) population will include all subjects treated with ACH-0145548
or placebo and for whom PD markers can be evaluated.
Pharmacokinetic analysis will be done using a validated computer program for the PK population. Based on the individual plasma concentration time data, using the scheduled sampling times, appropriate including, but not limited to, standard PK parameters of ACH-0145548 will be derived from the
bioanalytical results. Descriptive statistics (number of subjects, mean/geometric mean, SD, med, min, and max) will be used to summarize the calculated PK parameters by dose levels.

Summary
Brief summary
ACH-0145548 is a new orally (by mouth) administered complement factor D (fD) inhibitor being developed by Achillion Pharmaceuticals Inc.for the treatment of complement mediated diseases. Many diseases are associated with inefficient control of complement or too much activity of the complement system.
This study will help determine the correct dose, whether this medication has any side effects and how effective it is at controlling the complement system.
A total of 28 subjects (18 active, 10 placebo) are planned for three treatment groups. Each healthy volunteer will receive a single dose of ACH-0145548 or placebo. Subjects will remain inpatient from Day 1 to Day 4 with telephone calls on Day 5 and 6 and follow up visits (days 7, 14 and 28). The total duration of participation for each of these subjects will be approximately 28 days, not including screening.
