VESTED
Start date: January 19, 2018
Phase: Phase 3
Study type: Interventional

The purpose of this study was to compare the virologic efficacy and safety of three antiretroviral (ARV) regimens, dolutegravir plus emtricitabine/tenofovir alafenamide, dolutegravir plus emtricitabine/tenofovir disoproxil fumarate, and efavirenz/emtricitabine/tenofovir disoproxil fumarate in pregnant women living with HIV-1 and to compare the safety of these regimens for their infants.

NCT ID: NCT03016533 Active, not recruiting - HIV Infections Clinical Trials

Dolutegravir Study in HIV-1 Participants Completing IMPAACT Studies P1093 and P2019

Start date: June 7, 2017
Phase: Phase 3
Study type: Interventional

Dolutegravir is a potent integrase strand transfer inhibitor. Abacavir/dolutegravir/lamivudine (ABC/DTG/3TC) is a fixed dose combination regimen containing two nucleoside reverse transcriptase inhibitors and dolutegravir. This is a phase 3b, non-randomized, open-label, multi-center, two treatment rollover study. The primary objective of this pediatric interventional study is to provide continued access to age appropriate formulations of investigational product (dolutegravir), either as Tivicay or as part of fixed dose combination ABC/DTG/3TC, for eligible participants who previously participated in parent studies P1093 (NCT01302847) or P2019 (NCT03760458) and who cannot locally access age appropriate formulations of dolutegravir or ABC/DTG/3TC in the public sector. The P1093 study was designed to evaluate the pharmacokinetics (PK), safety, tolerability and antiviral activity of dolutegravir in combination with optimized background regimens in human immunodeficiency virus type 1 (HIV-1) experienced adolescents and children as well as treatment naïve infants and toddlers. The P2019 study was designed to evaluate PK, safety, tolerability and antiviral activity of ABC/DTG/3TC dispersible and immediate release tablets in HIV-1-infected children. Participants who have tolerated investigational product in the parent studies without any significant toxicity or signs of virologic failure leading to the permanent discontinuation of investigational product and withdrawal from the parent study will be considered for this open label continued access study. Participants will receive their age/weight appropriate dose of investigational product as defined in the parent study. The duration of participation in the study will extend until age appropriate formulations of Tivicay or ABC/DTG/3TC receive local (by country) regulatory approval and are available in those countries from another source (e.g. government programs, aid programs, assistance programs, etc.) or the participant is no longer deriving benefit from treatment or meets a protocol defined reason for discontinuation. Participants will be enrolled after all screening procedures have been completed. In most cases, the Screening visit will overlap with the participants penultimate visit on the parent study (at Week 180 of P1093, or Week 36 of the P2019 study). Participants who meet all entry criteria may enroll and will be seen in the clinic every 12 weeks for a safety evaluation and to receive investigational product. It is estimated that no more than 300 participants will be enrolled in this study. Tivicay is a registered trademark of ViiV Healthcare.

NCT ID: NCT02832544 Completed - Clinical trials for Rheumatic Heart Disease

INVestIgation of rheumatiC AF Treatment Using Vitamin K Antagonists, Rivaroxaban or Aspirin Studies, Non-Inferiority

INVICTUS-VKA
Start date: August 22, 2016
Phase: Phase 3
Study type: Interventional

This program is a comprehensive evaluation of rheumatic valvular heart disease (RVHD), Atrial fibrillation (AF)/flutter and stroke. A prospective, randomized, parallel group, open-label clinical trial of rivaroxaban versus standard vitamin K antagonists (VKA) therapy to evaluate non-inferiority of rivaroxaban to VKA, with testing for superiority if non-inferiority is satisfied.

NCT ID: NCT02803827 Completed - Clinical trials for Acute Gastroenteritis

Optimizing the Management of Acute Diarrhoeal Disease

Start date: June 2016
Phase: Phase 3
Study type: Interventional

Many children admitted to hospital in Botswana without bloody diarrhoea are presumed to have viral gastroenteritis and so not treated with antibiotics - but they may indeed have a treatable cause for their illness. The investigators will conduct a randomized trial to see if rapid testing using novel methods to identify potentially treatable causes of diarrhoea leads to improved outcomes. The investigators will also be randomizing children to Lactobacillus reuteri DSM (daughter strain) 17938 therapy versus placebo (the standard of care) to see if this treatment decreases the duration of diarrhoea. The proposed study is a large multi-centre trial following the previous pilot trial.

NCT ID: NCT02752061 Completed - HIV Clinical Trials

Potlako: A Programmatic Intervention to Improve Access to Timely Oncology Care

Start date: May 13, 2016
Phase: N/A
Study type: Interventional

Diagnostic and treatment delays contribute substantially to disparities in cancer morbidity and mortality between low- and middle- income countries (LMICs) and high-income countries. Individuals present with advanced stage disease resulting in minimal chance for cure or long-term survival. The Potlako project will implement and evaluate a multifaceted intervention to test the hypothesis that a package of enhanced coordination of care including an electronic messaging, transportation support, and training targeted at generalist clinicians at primary and secondary level facilities, can reduce time to diagnosis and stage at diagnosis for HIV-infected individuals with cancer.

NCT ID: NCT02581527 Completed - Clinical trials for Pulmonary Tuberculosis

A Randomised Trial to Evaluate Toxicity and Efficacy of 1200mg and 1800mg Rifampicin for Pulmonary Tuberculosis

RIFASHORT
Start date: February 1, 2017
Phase: Phase 3
Study type: Interventional

In this trial, the investigators are assessing whether giving an increased dose of rifampicin to patients receiving the standard treatment for tuberculosis is safe and, when given for 4 months only, will also result in greater and faster killing of the tubercle bacillus in the lungs and result in relapse rates similar to those found in the World Health Organisation (WHO) recommended standard 6 month regimen.

Start date: May 2016
Phase: Phase 2
Study type: Interventional

This study will evaluate the safety and efficacy of the human monoclonal antibody (mAb) VRC-HIVMAB060-00-AB (VRC01) in preventing HIV-1 infection in high-risk, HIV-uninfected women.

NCT ID: NCT02538952 Completed - Tuberculosis Clinical Trials

Evaluating Accuracy, Impact, and Operational Challenges of GeneXpert Use for TB Case Finding Among HIV-infected Persons

XPRES
Start date: August 1, 2012
Phase: Phase 4
Study type: Interventional

Background: In Botswana, as in the rest of sub-Saharan Africa, undiagnosed TB or TB diagnosed late in the course of disease is thought to be the most common cause of death among HIV-infected persons. Interventions for Evaluation: The Xpert MTB/RIF assay for the GeneXpert platform (Xpert) has a TB diagnostic sensitivity of 82.4%, significantly superior to that of smear microscopy (44.6%). In line with WHO guidelines, the Botswana Ministry of Health (MOH) and CDC rapidly rolled out the Xpert device and a new Xpert-based diagnostic algorithm in service of 22 HIV care and treatment clinics. To maximize impact of the Xpert device in improving detection of active TB, Xpert rollout was preceded by strengthening of TB screening procedures by: (1) adopting the WHO-recommended 4-symptom TB screen for adults; (2) situating trained TB case-finding nurses in facilities; and (3) training health facility personnel in TB diagnostic algorithms. The combination of these strengthened TB screening procedures and rollout of the Xpert device is referred to as the "Xpert package" in this protocol. Key Evaluation Objectives: The protocol has two key objectives: (1) to evaluate whether the new MOH-recommended Xpert-based TB diagnostic algorithm for new adult HIV clinic enrollees is more sensitive than the pre-Xpert smear-microscopy-based algorithm in diagnosing culture-positive TB disease; and (2) to evaluate the impact of the whole "Xpert package" on all-cause mortality during the first 6 months of ART, among adult patients. Design: Stepped-wedge cluster randomized trial. Sample Size: 6,136 patients were prospectively enrolled to meet the first primary objective. A retrospective cohort of 10,131 persons was also enrolled to meet the second objective. Projected power to meet both objectives is >80%. Time line: Prospective cohort enrollment started in July 2012 and was complete by March 2014. Retrospective cohort enrollment was complete by March 2015. Patient follow-up and data entry will be complete in March 2016 at which time analysis to answer the first two primary study questions will be possible.

NCT ID: NCT02455583 Completed - HIV Clinical Trials

Start date: August 2014
Phase: N/A
Study type: Interventional

The purpose of this study is to examine the effectiveness of an HIV prevention intervention called Project AIM (Adult Identity Mentoring) to delay onset of sexual activity and reduce sexual risk behaviors among students (approximate ages 12- 17 years) in junior secondary schools (Form 1 - 3) in Eastern Botswana.

NCT ID: NCT02412436 Completed - Tuberculosis Clinical Trials

PK Study of Rifampicin Interactions With DMPA and Efavirenz in TB

PRIDE-HT
Start date: November 3, 2015
Phase: Phase 2
Study type: Interventional

This study was done to evaluate the effect of HIV and TB treatment on a commonly used birth control method. It enrolled women who were infected with HIV and TB and were taking efavirenz (EFV; Sustiva®; an anti-HIV medication), rifampicin (RIF; an anti-TB medication), and isoniazid (INH; an anti-TB medication). The purpose of this study was to find out the best frequency to give depot medroxyprogesterone acetate (DMPA; a hormonal birth control method that is given as a shot every 3 months) in these women. This study also tried to find out if a 150 mg injection of DMPA was effective in preventing ovulation, the process by which the ovaries (the ovaries are part of the female reproductive system) release an egg for fertilization, for 12 weeks in women who are taking EFV and RIF. Another purpose of this study was to find out if it is safe to take RIF, EFV and DMPA at the same time.
