3,254 Clinical Trials for Various Conditions
Cabotegravir is being developed for the treatment of human immunodeficiency virus (HIV) 1 infection. Specifically, it is being developed as a component of a 2-drug maintenance regimen (post-induction of viral suppression) that includes rilpivirine. Rilpivirine requires food for optimal absorption; therefore the recommended intake of cabotegravir in the planned Phase 3 treatment studies is with food regardless of fat or calorie content, when administered along with rilpivirine. This is a single-center, randomized, open-label, two-way crossover study in healthy adult subjects to assess the effect of a high fat meal on the single dose pharmacokinetics of CAB 30 mg. Approximately, 24 subjects will be enrolled in the study and will be screened for 30 days. Twelve subjects with at least 10 hours of fasting will be randomized to receive a single dose of cabotegravir orally (Schedule 'A'). The remaining 12 subjects will receive a single dose of cabotegravir orally along with high fat meal (Schedule 'B'). After 15 days, the subjects earlier undergoing 'Schedule A' will be switched to 'Schedule B' and those undergoing 'Schedule B' will undergo 'Schedule A'. All the subjects will be followed up to 30 days from the day of receiving first dose of cabotegravir to evaluate the effect of a high fat meal on the pharmacokinetics of cabotegravir.
This is a single-center, open-label, three-period, fixed-sequence cross over study in healthy adult subjects. A total of approximately 16 healthy subjects will be enrolled to provide data from 12 evaluable subjects. Subjects will have a screening visit within 30 days prior to the first dose of study drug, three treatment periods, and a follow-up visit 7-14 days after the last dose of study drug. There will be a washout period between Period 1 and Period 2 but no washout between Period 2 and Period 3. Day 1 of Period 3 will be the day after Day 5 of Period 2.
The purpose of this trial is to assess the non-inferior antiviral activity of GSK1349572 50 mg plus Abacavir/Lamivudine once daily versus Efavirenz/Emtricitabine/Tenofovir disoproxil fumarate (ATRIPLA® a trade mark of Bristol-Myers Squibb and Gilead Sciences LLC) over 48 weeks; non-inferiority will also be tested at Week 96. This study will be conducted in HIV-1 infected ART-naïve adult subjects. Long term antiviral activity, tolerability, safety, and development of viral resistance will be evaluated.
The purpose of this trial is to assess the non-inferior antiviral activity of GSK1349572 50 mg once daily versus RAL 400mg twice daily over 48 weeks; non-inferiority will also be tested at Week 96. Both GSK1349572 and RAL will be given in combination with fixed-dose dual NRTI therapy (ABC/3TC or TDF/FTC). This study will be conducted in HIV-1 infected ART-naïve adult subjects.
This study was designed to test the efficacy, safety, tolerability and durability of the antiviral response between atazanavir (ATV) + ritonavir (/r) + abacavir/lamivudine(ABC/3TC) Fixed dose combination (FDC) each administered once daily (QD) for 36 weeks followed by randomization to either a simplification regimen of ATV or continuation of ATV +/r for an additional 48 weeks, each in combination with ABC/3TC in antiretroviral (ART)-naive, HIV-1 infected, HLA-B\*5701 negative subjects. All subjects who complete the 84-week study will be eligible to enter the treatment extension phase and continue for an additional 60 weeks. The purpose of this extension is to obtain longer term treatment data in subjects who have completed the 84-week study.
This is a proof of concept (POC) single arm study of GW640385, a protease inhibitor, in combination with RTV and 2 or more nucleoside reverse transcriptase inhibitors (NRTI) backbone. This study has a 48 week duration and is open to both treatment naive and experienced patients who are HIV positive. There are 3 intensive pharmacokinetic (PK) visits.
This is a two phase study (randomised and non-randomised phase). The randomised phase will initially examine 4 blinded doses of GW640385 boosted with rtv (with continuation of current background therapy) in comparison to an ongoing, open-labeled rtv-boosted protease inhibitor (PI) regimen for 15 days. At the Day 15 visit, all subjects will optimize background therapy. Additionally, subjects receiving the lowest dose of GW640385 will be re-randomised to one of the higher doses and subjects in the control arm will receive a new rtv-boosted PI based on resistance testing at screening. Subjects will remain in the randomized phase on one of these 4 continuing treatment arms for at least 48 weeks. An interim analysis will occur during the randomised phase to select for a dose of GW640385 to evaluate further in Phase III studies. After dose selection subjects will move to the non-randomised phase of the study. In the non-randomised phase subjects who are receiving GW640385 will be assigned to final selected dose for assessment of long term safety, tolerability, pharmacokinetics, and antiviral activity.

This study will be conducted in two Parts to confirm the acceptability/selection of a tablet formulation for future clinical development of GSK2838232. Part 1 of the study will assess single ritonavir (RTV)-boosted doses of a new tablet formulation given with food (containing approximately 30% fat) against the reference capsule formulation also given with food and then will assess the impact of fasted conditions on the tablet performance. In Part 2, non-boosted GSK2838232 will be given as once-daily tablet doses for 11 days in a separate group of subjects, assuming the tablet performance is considered acceptable from Part 1. Approximately 16 healthy subjects will be enrolled to provide at least 12 evaluable subjects through the three study periods in Part 1. 10 healthy subjects will be enrolled to provide at least 8 evaluable subjects through the single study period in Part 2. The maximum duration of study participation will be approximately 9 to 10 weeks for Part 1; and 8 to 9 weeks for Part 2.
This study aims to compare the bioequivalence of two experimental fixed dose combination (FDC) tablets versus single entity products of dolutegravir (DTG) and lamivudine (3TC) in healthy adult subjects. The study will be carried out in two parts. Part 1 of the study will be open label, up to 3 periods design with a wash out period of at least 7 days between treatment periods. Subjects will be randomized to receive either single entities or formulation 1 FDC of DTG and 3TC in a crossover manner in first 2 periods. The first 16 subjects who complete the first two treatment periods and consent to continue will receive a single dose of FDC formulation 1 tablet administered with a high fat meal for a third treatment period. In Part 2 of the study, subjects will be randomized to receive either single entities or formulation 2 FDC of DTG and 3TC in a crossover manner in first 2 periods. Similarly the first 16 subjects will then receive FDC formulation 2 tablets with high fat meal in treatment period 3. Subjects will have a follow-up visit within 7-14 days after the last dose of study drug. Approximately 76 healthy subjects will be included in Part 1 of the study and if Part 2 of the study is conducted, another 76 healthy subjects will be included. The total duration will be approximately 11 weeks.
GSK2838232 is a novel HIV-1 maturation inhibitor (MI) that is being developed for the treatment of HIV-1 infection in combination with other antiretroviral therapy (ART). This study will be a 10-day monotherapy, open-label, adaptive, dose ranging, repeat-dose study. This study will be conducted in two Parts (Part A and Part B) consisting single daily doses of GSK2838232 and Cobicistat from Day 1 to Day 10. This proof of concept open-label study will be aimed to characterize the acute antiviral activity, pharmacokinetics (PK), the relationship between PK and antiviral activity, and safety of GSK2838232/cobi administered across a range of doses over 10 days in HIV-1 infected patients. A cohort of 10 subjects will be studied in Part I followed by interim (go/no-go) analysis of Part A data. On completion of an interim analysis of part A data, further cohorts of 8 subjects will then be studied in Part B in a parallel design in two or more cohorts (depending upon the data obtained in Part A). Approximately 34 HIV-1 infected treatment-naive subjects will be enrolled during the study. Subjects in both parts will have a screening visit within 30 days prior to first dose and a follow-up visit 7-14 days after the last dose. Maximum duration of study participation will be approximately 6 Weeks.
This is an open-label, randomized, crossover study in healthy adult subjects with 5 treatment groups over 5 dosing periods. This study will evaluate pharmacokinetic parameters and relative bioavailability of a dispersible, fixed-dose combination (FDC) tablet of TRIUMEQ™ (\[abacavir, ABC\]/\[dolutegravir, DTG\]/\[lamivudine, 3TC\]) when dispersed and consumed under four different dosing conditions in comparison to an oral dose of TIVICAY™ (DTG) + EPZICOM™ (ABC/3TC) non-dispersible tablets administered in the fasted state. Approximately 20 subjects will be randomized, each to one of 5 treatment groups. The total duration of participation of a subject in this study will be approximately 10-11 weeks. It will include a screening visit within 30 days prior to the first dose of study drug, five treatment periods each with a single dose of study drug per treatment period and a follow up visit within 7 10 days after the last dose. There will also be a washout of at least 7 days between doses in each treatment period. TRIUMEQ, EPZICOM, and TIVICAY are trademarks of the GlaxoSmithKline group of companies.
An oral dose in healthy subjects to determine the relative bioavailabilty of BMS-626529 administered as BMS-663068
GSK2838232 is a Human Immunodeficiency Virus (HIV) maturation inhibitor being developed for the treatment of HIV in combination with other antiretroviral therapy (ART). The primary objectives of this study are to investigate the safety, tolerability, and pharmacokinetics (PK) of single and repeat doses of GSK2838232. This study will be a double-blind, placebo-controlled, single and repeat dose escalation study. This study will be conducted in two Parts: single escalating doses (Part 1A and 1B), and repeated escalating once daily (QD) doses for 11 days (Part 2) of GSK2838232 co-dosed with RTV. During Part 1A, single doses of GSK2838232 (as of active pharmaceutical ingredient-powder in bottle \[API PiB\]) 50 milligrams (mg), 100mg and 200mg will be administered with RTV. Part 1B will evaluate the relative bioavailability of single doses of crystalline active pharmaceutical ingredient (API) Immediate Release Tablet (IR) tablets versus API PiB as reference, administered with RTV. In Part 2, multiple doses of GSK2838232 will be co-administered with RTV 100mg QD for 11 days as sequential dose cohorts. Maximum duration of study participation will be approximately 10 weeks.
The purpose of the study is to evaluate the bioequivalence between Fixed-dose Combination (FDC) tablet formulation of Dolutegravir (DTG) 50 milligrams (mg) and Rilpivirine (RPV) 25 mg versus co-administration of the separate tablet formulations of DTG 50 mg plus RPV 25 mg, in the fed state. This pivotal bioequivalence study, is to serve as a pharmacokinetic (PK) bridge to the ongoing Phase 3 trials with the separate agents. This study will be conducted under fed conditions to appropriately mimic the conditions in the Phase 3 trials. This is a single-center, randomized, open-label, 2-period, single-dose, crossover study. A minimum of 86 healthy adult subjects will be randomized such that a minimum of approximately 82 evaluable subjects complete the study. The total duration of participation of a subject in this study will be approximately 8 weeks which includes a screening visit within 30 days prior to the first dose of study drug, two treatment periods each with a single dose of study drug and a follow-up visit within 12-17 days after the last dose of study drug. There will be a washout of at least 21 days between each dose of study drug. A blinded (for treatment) review of DTG and RPV plasma concentration data for approximately the first 40 subjects will be conducted. If the within-subject coefficients of variation (CVw%) for either DTG or RPV maximal drug concentration (Cmax) values are \>=31%; a sample size re-estimation will be employed and additional subjects (beyond the 86 planned) will be randomized for treatment in the study. Following the re-estimation, it is possible that up to approximately 154 healthy adult subjects (68 new subjects in addition to the planned 86 subjects above) will be randomized such that a maximum of approximately 146 evaluable subjects could complete the study.
Dolutegravir (DTG) and lamivudine (3TC) are indicated in combination with other antiretroviral agents for the treatment of human immunodeficiency virus type 1 (HIV-1) infection. Fixed dose combination (FDC) tablets of existing approved drugs are preferred by many patients and offer the potential for increased patient adherence and consequently a reduced likelihood of virological failure and viral resistance. The purpose of the present study is to evaluate the relative bioavailability of two experimental FDC tablets of DTG and 3TC relative to co-administration of the single entity products in healthy adult subjects. This study will be conducted as a randomized, open label three-way, crossover design with 6 treatment sequences in approximately 30 subjects. Each subject will have a screening visit within 30 days prior to the first dose of study drug, three treatment periods each with a single dose of study drug and a follow-up visit within 7-14 days after the last dose of study drug. There will be at least 7 days washout between dosing periods. The total duration of participation of a subject in this study will be approximately 9 weeks.
The purpose of this study is to evaluate how BMS955176 affects pharmacokinetics (PK) of Dolutegravir (DTG) and also how DTG administration affects the PK of BMS955176
The purpose of this study is to estimate the effect of high fat meal and increased gastric pH on BMS-663068 bioavailability
The study is being conducted to assess the effect of multiple doses of BMS-663068 on the exposure of methadone in subjects on a stable dose of methadone, and the exposure of buprenorphine and norbuprenorphine in subjects on a stable dose of buprenorphine and norbuprenorphine.
Lamivudine (3TC) is a nucleoside analogue indicated in combination with other antiretroviral agents for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in adults and children. Documented literature elucidates that simultaneous administration of multiple sorbitol-containing products could increase the potential for a significant interaction and may contribute to the lower 3TC exposures. In this study several sorbitol doses (3.2 gram (g), 10.2 g, and 13.4 g solutions) will be administered with lamivudine to investigate dose dependency and mimic the situation where multiple sorbitol-containing antiretroviral medications may be co-administered with lamivudine. It will be open label, randomized, 4-way crossover (by William's design method) design at a single centre. Randomized participants will receive a single dose of each of four treatments after wash out period of minimum 7 days.
The purpose of the study is to determine the effect of multiple doses of BMS-955176 on the QT interval corrected with Fridericia's method (QTcF) in healthy subjects.
