COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Titles & IDs
Public title
An interventional study to evaluate the effects of dosages on the Pharmacokinetics (PK, the measure of how the human body processes a substance), Tolerability (how well a substance is tolerated by participants), and Safety of different dosages of Amphotericin B (iCo-019) when given to healthy participants as multiple oral doses.
Scientific title
A Phase 1b, Single-Center, Double-Blind, Randomized Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of 100 mg and 400 mg Oral Amphotericin B (iCo-019) or Placebo Administered for 10 Days in Healthy Subjects

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
iCo-019 (oral Amphotericin B) 100mg gelatin capsule taken orally.
Cohort 1: 1 x 100 mg capsule or 1x placebo capsule for 10 days once per day
Cohort 2: 4 x 100 mg capsule or 4x placebo capsule for 10 days once per day

A Safety Evaluating Committee (SEC) will review data from the first cohort (100 mg of oral Amphotericin B or placebo) once completed and make a recommendation whether it is safe to proceed with multiple dosing of 400 mg of oral Amphotericin B or placebo in the second cohort.
Adherence to the study treatments will be monitored by inpatient stay and observation; participants in will be confined to the study unit from check-in on Day -1 through to
discharge at 48-hour post last dose.

Treatment: Drugs
Comparator / control treatment
The placebo capsules will be composed of the same inactive ingredients (excipients only) used in the IP formulation.
Control group
Placebo

Outcomes
Primary outcome [1] 322165 0
To evaluate safety and tolerability after repeated administration of 100 mg and 400 mg doses of oral Amphotericin B (iCo-019) for 10 days in healthy subjects
This will be assessed by looking at the incidence, severity, causality, and seriousness of adverse events;
changes in clinical laboratory evaluations; changes in vital signs parameters, and ECGs; changes in physical examination findings.
Possible adverse events (based on common side effects of IV formulation of Amphotericin B) include: nausea, rash, mild headache.
Timepoint [1] 322165 0
Adverse event information will be recorded from the time of admission to the study unit until 10 days after the last dose of study drug.
Clinical laboratory evaluations of serum chemistry, hematology, urine chemistry and urinalysis will be performed at Screening, Check-in (Day -1), pre-dose on Days 2, 5, 7 and 10; at Discharge from clinic (48 hours post last dose); at Follow-up (Day 12) and End of Study (Day 20)/Early Withdrawal.
Vital signs, including blood pressure, pulse rate, respiratory rate and oral temperature will be measured at Screening; Check-in (Day -1); Pre-dose, and 2 hours post-dose on Day 1.
Blood pressure and heart rate will be measured Pre-dose, and 2 hours post-dose on Days 2, 5, 7, and 10; at Discharge from clinic (48 hours post last dose); at Follow-up (Day 12) and End of Study (Day 20)/Early Withdrawal.
12-lead ECGs will be obtained at: Screening; Check-in (Day -1); Pre-dose on Day 1; 2 hours postdose on Days 5, 7, and 10; at Discharge from clinic (48 hours post last dose); at Follow-up (Day 12) and End of Study (Day 20)/Early Withdrawal.
Secondary outcome [1] 377554 0
To evaluate pharmacokinetic profile after repeated administration of oral Amphotericin B (10 days) in healthy individuals.
Blood samples will be collected and the following PK parameters will be assessed in plasma-
Peak concentration (Cmax)
Time to peak concentration (Tmax)
terminal elimination rate constant (Kel)
half-life (t1/2)
Area under the concentration-time curve from time 0 to the last measurable concentration timepoint
(AUC0-t)
Area under the concentration-time curve from time 0 and extrapolated to infinity (AUC0-infinity)
area under the concentration-time curve from time 0 to 24 hours (AUC0-24)
Timepoint [1] 377554 0
Blood samples for PK will be collected at the following timepoints:
Pre-dose, and 2, 4, 6, 8, 10, 12, and 24 hours post- dose on Days 1 and 10
Pre-dose on Days 2, 5 and 7.
Day 11 (36 hours post last dose)
Day 12 (48 hours post last dose)
Day 15
Day 20
