Study type
Description of intervention(s) / exposure
Part 1: Healthy Volunteers will receive one of 5 single ascending doses (SAD) of ALS-002158 ranging from 50 mg to 750 mg. ALS-002158 or placebo is administered orally via a syringe.
Subjects in Part 1 and subjects in Part 3 will receive standardized diets at scheduled times that do not conflict with study-related procedures.

Prior to each dose of study medication, subjects will fast from food for at least 8 hours overnight until 4 hours post-dose. Except as part of dose administration, water may be consumed freely until 1 hour prior to dosing through 2 hours post-dosing.

Cohort 1: 50mg
Cohort 2: 100mg
Cohort 3: 300mg
Cohort 4: 500mg
Cohort 5: 750mg

Part 2: Eight Healthy Volunteers from Cohort 3 in Part 1 will receive a second single dose ALS-002158 or placebo (with a washout period of at least 7 days) to assess food effects on pharmacokinetics.

Subjects in Part 2, the food effect study phase, will be given a standardized high-fat content meal within 30 minutes of their second dose; the meal will be completed 10 minutes prior to dosing. The meal will consist of the following:
Two eggs fried in butter
Two strips of bacon
Two slices of toast with butter
Four ounces of hash brown potatoes (fried with butter)
Eight ounces (240 mL) of whole milk

Part 3: Subjects with CHC genotype 1 infection will receive one of 3 doses of ALS-002158 (100 mg, 300 mg, or 500 mg) or placebo for 7 days.
Prior to each dose of study medication subjects will fast from food for at least 8 hours overnight until 4 hours post dose. Except as part of dosing water may be consumed freely until 1 hour prior & 2 hours after dosing. Dosing may occur with food depending on the outcome of Part 2, the food effect study.

Subjects may be dosed in a staggered fashion to accommodate post dosing assessments. Dosing should occur at the same time each day +/- 5 minutes
(e.g., subject 1 is dosed at 7:00AM on MAD Days 1 through 7, subject 2 is dosed at 7:05AM on MAD Days 1-7, etc)

Treatment: Drugs
Comparator / control treatment
There is no comparator, however at the end of the study, the Sponsor will provide access to triple therapy (pegylated interferon, ribavirin and telaprevir) for subjects with CHC who have participated in Part 3.

The placebo will consist of the solution vehicle
containing 60% PEG-400 (Polyethylene glycol 400), 20% water for irrigation and 20% vitamin E TPGS (d-alpha tocopheryl polyethylene glycol 1000 succinate).
Control group

Primary outcome [1] 286380 0
To evaluate the safety and tolerability of single and multiple doses of ALS-002158 administered to Healthy Volunteers and subjects with CHC genotype 1 infection

This will be done through safety and tolerability testing and will be evaluated continuously throughout the study.

Safety evaluation will include Adverse Events and Serious Adverse Events, vital signs, laboratory tests (including hematology, and serum chemistries), ECGs, physical examination, urinalysis, and pregnancy tests.

Clinical laboratory variables, including hematology, serum chemistries, urinalysis, and urine pregnancy testing will be assessed at screening.

Hematology, serum chemistries, and urine pregnancy testing will be evaluated periodically during treatment and follow-up as indicated.

Vital signs, including resting pulse, respiratory rate, blood pressure, and body temperature.

Part 3 will commence when the third dose of Part 1 is found to be generally safe and tolerable based upon review of the blinded safety and available PK data by the PI and the

Dosing may occur in a fed or fasted state depending on the outcome of Part 2.

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
An independent statistician will be appointed to generate the randomization list and the sealed decoding envelopes. This statistician will not perform the study statistical analysis. Using the Biometrics server, the independent statistician will create a secure directory for the randomization list, with sole access to him and the assistants of the unit. The independent statistician will generate the randomization list and integrate this list in a WORD document.

In order to centralize the randomization and to allocate the randomization numbers in chronological order to the centers, once a patient’s eligibility is confirmed by the investigator, a randomization request form will be filled in by the site and addressed to the BIOTRIAL CTM and lead CRA. A scan of the completed randomization request document should be sent by email between 9:00 and 18h00 CET and a minimum of 4 working days before the expected Day 1.

The BIOTRIAL CTM and/or lead CRA will then complete the randomization request form with the next available randomization number and send it back by email to the site. He will also address it to the BIOTRIAL independent statistician.

4. Upon reception, the BIOTRIAL independent statistician will complete the form with the corresponding treatment to be allocated to the subject and send it by email to an un-blinded person at the investigational centre; most likely the local pharmacy.

In the absence of the independent statistician, another person of the unit (not involved in the study) will be granted access to the randomization list.

The contact information (name, address, e-mail) of each person to whom should be addressed the randomization code must be identified for each centre.

Each centre taking part in the study will receive a global set of sealed decoding envelopes permitting, if necessary, to break the code for all possible randomization numbers.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Cohorts are to be comprised of 10 subjects of which 8 will receive active drug and 2 will receive placebo. The randomization will be performed to maintain a ration of 4 active: 1 palcebo in 2 blocks of 5 subjects.

This will be done by the Sponsor and BIOTRIAL.

Brief summary
This study is to assess the safety and tolerability and how the investigational drug acts in the body. Healthy volunteers are being used for this trial and patients who suffer from Chronic Hepatitis C infection.
There will be one dose given to the healthy volunteers first and then the results from that will determine the dose levels of the Investigational product to be given in the second part of the study to healthy volunteers. They will also test a dose given before eating and after eating a meal.
In the third part of the study, the results from these two parts will determine dosing for patients who suffer from CHC.
