TMC114-C201: A Study to Determine the Antiviral Activity of TMC114 in Patients With Multiple Protease Inhibitor (PI) Resistant Human Immunodeficiency Virus (HIV) Strains

May 18, 2011 updated by: Tibotec Pharmaceuticals, Ireland

A Phase IIa Open-label, Randomized Trial to Determine the Antiviral Activity in 60 HIV Positive Subjects With Multiple PI Resistant Strains, Receiving Either Control Treatment or a Daily Dose of 800, 1600, 2400 or 3600 mg TMC114 (Darunavir) for 13 Days Followed by a Single Dose on Day 14

The purpose of this study is to determine the antiviral activity, safety and tolerability of 14 days of different doses of TMC114 to treat HIV-1 positive patients whose condition is failing on a current treatment regimen that includes a protease inhibitor (PI) (a medication used to reduce the amount of HIV virus in the blood).To be considered for the study, patients must have a documented resistance to at least 2 of the current PIs. Pharmacokinetics and pharmacodynamics of TMC114 will also be assessed.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a Phase lla open-label (all people involved know the identity of the treatment), randomized (study drug assigned by chance), controlled (the patients of the control group continue the failing regimen), dose-finding study to determine the antiviral activity, safety and tolerability of a 14-day treatment with TMC114 (a protease inhibitor) for treatment of human immunodeficiency virus type 1 (HIV-1) positive patients who are considered resistant to (failing to improve on) 2 or more protease inhibitors (PIs). Sixty HIV-1 positive patients, who are resistant to multiple PIs as confirmed by specialized testing (virtual phenotyping) and who are currently failing to improve on a treatment regimen that contains a PI, will be randomly assigned to one of 5 treatment groups. Those randomized to the control group will continue their current therapy (consisting of PIs and Nucleoside Reverse Transcriptase Inhibitor(s) (NRTIs)). Those randomized to the TMC114 treatment groups will receive the study drug as a substitute for all the PIs in the current failing treatment regimen at the following dose levels: 400 or 800 mg twice a day, or 800 or 1200 mg three times a day for 13 days followed by a single dose on day 14. The dose of the NRTIs (NRTIs are drugs that suppress replication of retroviruses) will remain unchanged until the end of the treatment period. The trial will involve a screening period of maximum three weeks, a 7-day run-in period (the period of time before study start when no treatment is given), a 14-day treatment period, followed by a 6- week follow-up period. The maximal trial duration will thus be twelve weeks. Primary objective is to determine the antiviral activity of TMC114 as well as the pharmacokinetics (how the drug is absorbed in the body, distributed within the body and how it is removed from the body over time) and pharmacodynamics (the study of the action of effects a drug has on the body) will also be assessed over the 2 week period.Safety will be followed at regular intervals during treatment and follow-up period. Safety assessments consist of regular lab assessments, ECG recording, vital signs, physical examination, body weight and Body Mass Index. Observation of and interview for adverse events will be done daily during the first week of treatment, every second day during the 2nd week of treatment, and at week 1, 3 and 6 of the follow-up period. In addition an Independent Data Monitoring Committee will evaluate the study data at regular intervals. Patients will be randomly assigned to one of 5 treatment groups: 400 or 800 mg twice a day for 13 days followed by a single dose on day 14, or 800 or 1200 mg three times a day for 13 days followed by a single dose on day 14. Patients randomized to the control group will continue their current therapy consisting of protease inhibitors (PIs) and Nucleoside Reverse Transcriptase Inhibitors (NRTIs).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study
