Description of intervention(s) / exposure
Approximately 72 healthy men or women will be enrolled in this study. There will be two parts to the study.

In the first part of the study approximately 48 healthy men and women will be enrolled in up to 6 single ascending dose cohorts comprising 8 subjects each. Participants within each cohort will be randomised to receive a single dose of either oral FP-100 (6 subjects) or oral placebo (2 subjects). All cohorts will be started with sentinel dosing. All doses will be administered under direct observation in the Phase 1 unit. The doses for each cohort are shown below.
Cohort 1a: 100mg
Cohort 1b: 400mg
Cohort 1c: 800mg
Cohort 1d: 1600mg
Cohort 1e: 2000mg
Cohort 1f: 2400 mg

Participants in Cohort 1d will receive FP-100 twice - once while fasting and again 3 days later after food.

In the second part of the study approximately 24 healthy men and women will be enrolled into up to 3 multiple ascending dose cohorts comprising 8 subjects each. Participants within each cohort will be randomised to receive multiple doses of either oral FP-100 (6 subjects) or oral placebo (2 subjects). Each dose regimen will be administered every day for 7 days (7 total doses). All doses will be administered under direct observation in the Phase 1 unit. The dose selection and dosing regimen for the second part of the study will be based upon the data from the first part of the study.

2. Participants must meet the following conditions:
a. Participants must be of non-childbearing potential, defined as
i. Postmenopausal (at least 1 year without menses and confirmed with follicle-stimulating hormone (FSH) levels greater than or equal to 40 mIU/mL at screening); or,
ii. Documented surgically sterile
or
b. If of childbearing potential, be non-pregnant (defined by a negative serum pregnancy test) and not lactating and agree to use highly effective contraception from screening through 30 days post dose.
c. Male participants, if engaging in sexual intercourse with a partner of childbearing potential, must be willing to use highly effective contraception from screening through 90 days post dose and agree not to donate sperm during this period.
d. Highly effective contraception involves the use of a condom for the male, plus one of the following for the female:

ii. Intrauterine device or intrauterine hormone-releasing system
iii. Bilateral tubal occlusion
iv. Vasectomised participant/partner with documented azoospermia 90 days after procedure, if that partner is the sole sexual partner
e. Participants who do not engage in heterosexual intercourse will be considered abstinent and do not require contraception. Women of childbearing potential who choose complete abstinence must continue to have pregnancy tests as per protocol. The reliability of sexual abstinence needs to be evaluated by the Investigator in relation to the duration of the clinical trial and the preferred and usual lifestyle of the participant. Abstinence must be an ongoing and usual lifestyle of the participant and complete abstinence must be maintained from screening through 30 days post dose.

Willing to refrain from over-the-counter or prescription medications or herbal, nutritional or dietary supplements from 7 days before first dose until the end of study assessments have been completed, except for limited use of paracetamol or in the case of necessary treatment of adverse events. Limited use of paracetamol is defined as 2 consecutive days of up to 4000 mg/day. These limits do not apply to its use for the necessary medical treatment of adverse events.

Statistical methods / analysis
This is an exploratory study and therefore it is not powered for inferential statistical analyses. It is anticipated that approximately 72 healthy male or female adult participants will be enrolled. This sample size is commonly used in studies of this design to obtain sufficient information on the safety, tolerability and PK

Summary
Brief summary
This project is testing the safety and pharmacokinetics of single and multiple oral doses of a new drug called FP-100. FP-100 is being developed for the treatment of patients with Lyme disease

You may be eligible for this study if you are a healthy adult man or woman aged between 18 and 55 years old.

In Cohorts 1a through 1f, participants will be randomised (assigned randomly, like flipping a coin) to receive single oral dose(s) of either the active study drug or placebo. In Cohorts 2a through 2c, participants will be randomised (assigned randomly, like flipping a coin) to receive multiple oral dose(s) of either the active study drug or placebo.

For subjects in Cohorts 1a, 1b, 1c, 1e and 1f, study participation will require 22 calendar days which will include 4 days (3 nights) in the CRU.
For subjects in Cohort 1d, study participation will require 22 calendar days which will include one stay of 7 days (6 nights) in the CRU.
For subjects in Cohorts 2a, 2b and 2c, study participation will require 22 calendar days which will include 9 days (8 nights) in the CRU.

It is hoped that this research will help determine the safety of FP-100 when given to healthy men or women so that it can be tested in patients with Lyme disease
