Brief summary
ACH-0145228 is a small molecule, orally administered complement factor D(fD) inhibitor being developed by Achillion Pharmaceuticals, Inc. for the treatment of complement alternative pathway (AP) mediated diseases. Many inflammatory, autoimmune, neurodegenerative and age-related diseases are associated with inefficient complement regulation or excessive 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 at least 54 healthy participants (38 active, 16 placebo) are planned for four separate multiple dose cohorts and one single dose cohort. Each healthy participant will receive either 14 days (MAD) or a single dose of oral doses of ACH-0145228 or placebo. Participants in MAD cohorts will receive a single 500-mg oral dose of ciprofloxacin 7 to 10 days before dosing. One additional single-dose cohort of 8 participants and one additional multiple-dose cohort of 10 participants may be enrolled if needed, for a maximum enrolment of 72 healthy participants. The total duration of participation for each participant in multiple-dose cohorts will be approximately 42 days, not including screening, and for each participant in single-dose cohorts will be approximately 28 days, not including screening.
Interventions
A total of at least 54 healthy participants (38 active, 16 placebo) are planned for four separate multiple dose cohorts and one single dose cohort. Each healthy participant will receive either 14 days multiple ascending dose (MAD) or a single dose (S1) of oral doses of ACH-0145228 or placebo. Participants in MAD cohorts will receive a single 500-mg oral dose of ciprofloxacin 7 to 10 days before dosing. One additional single-dose cohort of 8 participants and one additional multiple-dose cohort of 10 participants may be enrolled if needed, for a maximum enrolment of 72 healthy participants. The first dose group (Cohort 1) will have 16 participants randomized 1:1 to active or placebo (8 active and 8 placebo), Cohort 2, 3, 4, and additional multiple-dose cohorts, if needed will each consist of 10 participants, randomized 4:1 to active or placebo (8 active and 2 placebo). The single-dose cohort (Cohort S1), and additional single-dose cohorts, if needed, will each consist of 8 participants, randomized 3:1 to active or placebo (6 active and 2 placebo). For single-dose cohort, a sentinel group consisting of one active and one placebo subject will be dosed 24 hours before the remaining 6 subjects. If no significant drug-related toxicity is identified in the first 24 hours in the opinion of the PI, then the remaining participants of the same Cohort may be randomized 5:1 to receive either active study medication or placebo treatment. Cohort 1 to 3 dose escalation decisions will be made based on review of safety data up to Day 14 and PK to Day 7 from the preceding dose. Dose escalation decision for Cohort 4 will be made based on review of safety data up to Day 14 and PK to Day 7 from Cohorts 1-3 and the safety and available PK and PD data to Day 4 from Cohort S1. For MAD cohorts, escalation to a higher dose may occur if the last dose was well tolerated. The predicted exposure may not exceed that observed at the highest dose evaluated in a single-dose setting. 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-0145228 will be 40 mg BID for Cohort 1, 80 mg BID for Cohort 2, 120 mg BID for Cohort 3, and 200 mg BID for Cohort 4. The maximum dose for MAD Cohorts will be 200 mg BID. Because the available data do not provide single-dose exposures high enough to support the planned 200 mg BID dose in Cohort 4, the single-ascending dose cohort (S1) must be completed before Cohort 4 is enrolled. Cohort S1 will receive a maximum single-dose of 240 mg. 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. MAD cohort 1 dose is 40 mg BID. This was determined based on the data from the SAD study (ACH228-001) and the available nonclinical toxicology and PK/PD data. The cohort S1 (SAD) dose for this study is 240 mg. This was determined based on the data from the SAD study (ACH228-001) and the available nonclinical toxicology and PK/PD data. The Cmax and AUC0-24 predicted for this doses is calculated to maintain a 10-fold or greater margin to the exposure observed at the NOAEL observed in nonclinical studies. MAD cohorts will be enrolled sequentially. Up to Cohort 3, all dose escalation decisions will be made based on review of safety data through at least Day 14 and PK through Day 7 from the preceding dose. The dose escalation decision for Cohort 4 will be made based on review of safety data through at least Day 14 and PK through Day 7 from Cohorts 1-3 and the safety and available PK and PD data up to at least Day 4 from Cohort S1. Cohort S1 may be enrolled at the convenience of the investigational site, including concurrently with Cohorts 1-3, but must be completed before Cohort 4 is enrolled.
