About this study
Official title: A Phase 1, First-in-Human Study to Evaluate the Safety, Tolerability, and Pharmacokinetic Profiles of Single Ascending and Multiple Oral Doses of MB-110 and to Evaluate the Antiviral Activity in Hepatitis C Virus Infected Patients
A Phase 1, First-in-Human, Randomized, Placebo-Controlled, Double-Blind Study to Evaluate the Safety, Tolerability, and Pharmacokinetic Profiles of Single Ascending and Multiple Oral Doses of MB-110 in Healthy Volunteers and to Evaluate the Antiviral Activity of MB-110 in Hepatitis C Virus Infected Subjects
Read the detailed description
The present study is divided into 2 parts. Part A is a randomized, double blind, placebo controlled, sequential ascending single and multiple oral doses design to evaluate the safety, tolerability, PK, and food effect of MB-110 in healthy volunteers.Part A will recruit 2 groups (Groups 1 and 2) of 8 healthy volunteers in each group. Within each group, 8 subjects will be randomized 6:2 to receive MB-110 versus placebo.Subjects in Group 1 will receive either 50 mg of MB-110 or placebo under fasted conditions during the first visit (Cohort 1); and either 50 mg of MB-110 or placebo under fed conditions during the second visit (Cohort 3) where food effect will be evaluated. Subjects in Group 2 will receive either 100 mg of MB-110 or placebo under fasted condition during the first visit (Cohort 2); or 200 mg of MB-110 or placebo under fasted condition during the second visit (Cohort 4). In Cohort 5, 8 subjects will be selected from Group 1, Group 2, or new recruitment if the washout time is insufficient from the previous cohort. Subjects in Cohort 5 will be randomized 6:2 to receive MB-110 at dose of 200 mg or placebo once daily for 5 consecutive days.
Part B is a randomized, double-blind, placebo-controlled, multiple ascending oral dose design to evaluate the safety, tolerability, PK, and antiviral activity of MB-110 in subjects infected with Hepatitis C virus genotype 1b, 2a, and 3a.Part B will recruit 3 cohorts (Cohorts 6, 7, and 8) of treatment-naïve HCV infected subjects in each cohort. In Cohort 6, 12 subjects infected with Hepatitis C virus genotype 1b will be randomized 5:5:2 to receive two dose levels of MB-110 or placebo once daily for 3 consecutive days. In Cohort 7, 6 subjects infected with Hepatitis C virus genotype 2a will be randomized 5:1 to receive MB-110 or placebo once daily for 3 consecutive days. In Cohort 8, 6 subjects infected with Hepatitis C virus genotype 3a will be randomized 5:1 to receive MB-110 or placebo once daily for 3 consecutive days.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
MB-110Drug
Also called DBPR110, NSFA10003S0
MB-110 is a novel, potent, and selective HCV inhibitor against the NS5A protein. In the preclinical studies, MB-110 demonstrated picomolar EC50s towards various genotypes and favorable pharmacokinetic properties to support the once daily dosing regimen.
PlaceboDrug
Also called Placebo of MB-110
It will be identical in appearance and similar in weight to the MB-110 hard-gel capsule.
| Study group | Role | What they receive |
|---|---|---|
| MB-110 | Experimental | oral hard-gel capsule formulation. One dose strength, 25 mg of MB-110, will be filled into the #00 hard-gel capsule. Receives: Drug: MB-110 |
| Placebo | Placebo comparator | in the same #00 hard-gel capsules. Receives: Drug: Placebo |

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
A Phase 1, First-in-Human, Randomized, Placebo-Controlled, Double-Blind Study to Evaluate the Safety, Tolerability, and Pharmacokinetic Profiles of Single Ascending and Multiple Oral Doses of MB-110 in Healthy Volunteers and to Evaluate the Antiviral Activity of MB-110 in Hepatitis C Virus Infected Subjects
Detailed description
The present study is divided into 2 parts. Part A is a randomized, double blind, placebo controlled, sequential ascending single and multiple oral doses design to evaluate the safety, tolerability, PK, and food effect of MB-110 in healthy volunteers.Part A will recruit 2 groups (Groups 1 and 2) of 8 healthy volunteers in each group. Within each group, 8 subjects will be randomized 6:2 to receive MB-110 versus placebo.Subjects in Group 1 will receive either 50 mg of MB-110 or placebo under fasted conditions during the first visit (Cohort 1); and either 50 mg of MB-110 or placebo under fed conditions during the second visit (Cohort 3) where food effect will be evaluated. Subjects in Group 2 will receive either 100 mg of MB-110 or placebo under fasted condition during the first visit (Cohort 2); or 200 mg of MB-110 or placebo under fasted condition during the second visit (Cohort 4). In Cohort 5, 8 subjects will be selected from Group 1, Group 2, or new recruitment if the washout time is insufficient from the previous cohort. Subjects in Cohort 5 will be randomized 6:2 to receive MB-110 at dose of 200 mg or placebo once daily for 5 consecutive days.
Part B is a randomized, double-blind, placebo-controlled, multiple ascending oral dose design to evaluate the safety, tolerability, PK, and antiviral activity of MB-110 in subjects infected with Hepatitis C virus genotype 1b, 2a, and 3a.Part B will recruit 3 cohorts (Cohorts 6, 7, and 8) of treatment-naïve HCV infected subjects in each cohort. In Cohort 6, 12 subjects infected with Hepatitis C virus genotype 1b will be randomized 5:5:2 to receive two dose levels of MB-110 or placebo once daily for 3 consecutive days. In Cohort 7, 6 subjects infected with Hepatitis C virus genotype 2a will be randomized 5:1 to receive MB-110 or placebo once daily for 3 consecutive days. In Cohort 8, 6 subjects infected with Hepatitis C virus genotype 3a will be randomized 5:1 to receive MB-110 or placebo once daily for 3 consecutive days.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing MB-110 in people with Chronic Hepatitis C, run by Microbio Co Ltd at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 30 inclusion and 45 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 5 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Ashley Hung (+886-2-2570-2088 ext. 390, ashley.hung@microbio.com.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of adverse events in cohort 1-4 (time frame: Up to 8 days (plus or minus 1 day)). The study lists 40 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Apr 2017.
