NCT ID: NCT03345875 Recruiting - Cervical Cancer Clinical Trials

Feasibility and Acceptability of HPV Self-Collection Cervical Cancer Screening and Treatment in Botswana

Start date: October 16, 2017
Phase: N/A
Study type: Interventional

Aims of the Study: To assess feasibility and acceptability of introducing HPV testing of self-collected vaginal specimens (self-collection for HPV) of women age 30-49 years, followed by visual assessment of the cervix for treatment (VAT) and treatment of women testing HPV positive at a district hospital, surrounding clinics and communities in Botswana. Background and Rationale: High HIV prevalence correlates with high rates of precancerous and cancerous changes on the cervix, and Botswana has the third highest HIV prevalence rate (22.2%) in the world. In Botswana, cervical cancer is the leading cause of cancer and cancer-related deaths among women. While the Government of Botswana has made cervical cancer a public health priority, and has provided cytology-based screening (Pap smears) for the past 20 years and in recent years began also offering VIA coupled with immediate cryotherapy for eligible precancerous lesions in a screen-and-treat (S&T) approach, the program still encounters multiple challenges. These include delays in reporting/receiving cytology results, referral bottlenecks for specialist care, and ultimately far fewer women being screened and treated than set targets. In response, in 2012 Botswana's Ministry of Health and Wellness (MoHW) developed a National Cervical Cancer Prevention Programme (NCCPP) Comprehensive Prevention and Control Strategy that includes implementing a demonstration project to gauge acceptability and obtain lessons that will be used in planning the roll-out of this screening method. As a result, the MoHW is exploring human papillomavirus (HPV) testing as a primary screening method with the future service delivery in mind through HPV testing, specifically using self-collected samples, as a primary screening method. HPV testing is more sensitive and reliable for the detection of cervical precancer and cancer than Pap testing and VIA. This increased sensitivity translates into two important benefits: 1) earlier detection of significant precancerous lesions that if treated results in a ~50% reduction in the incidence of cervical cancer within 4-5 years compared to Pap testing and 50% reduction in related deaths within 8 years compared to Pap testing and VIA and 2) lower cancer risk for many years for those with a negative result, which permits screening at an extended interval of 5-10 years. The Xpert HPV test, which will be used in this study, has high sensitivity (100%) and relatively high specificity (81.5%) for CIN. HPV tests run on the GeneXpert® machine allow multiple tests (four in the model to be used in this study) to be run in an hour.

NCT ID: NCT03336346 Recruiting - HIV Infections Clinical Trials

Effect of Dolutegravir on Etonogestrel Levels in HIV-infected Women in Botswana

Start date: November 15, 2017
Phase: N/A
Study type: Observational

The primary aim is to assess if etonogestrel (ENG) implant users taking dolutegravir (DTG) have a 20% or greater change in their ENG plasma levels, compared to women taking no antiretroviral therapy (ART). A secondary aim is to assess whether ENG implant users taking dolutegravir have significantly higher ENG plasma levels than ENG implant users taking efavirenz. This is a cross-sectional, non-randomized evaluation to compare ENG levels at least 3 months post-implant insertion in three groups of women: 1) women using DTG-based ART (n=90), 2) women using EFV-based ART (n=90), and 3) women using no ART (not HIV infected) (n=90). This study will be conducted in Botswana in Southern Africa among women using the ENG implant, and involves a one-time collection of blood and questionnaire.

NCT ID: NCT03213028 Recruiting - Family Planning Clinical Trials

Family Planning Service Delivery Integration For HIV Positive And At-Risk Women In Botswana: A Hybrid Type 2 Clinical Intervention And Implementation Strategy

Start date: August 18, 2017
Phase: N/A
Study type: Interventional

The goal of this pilot study is to assess both implementation outcomes (acceptability, feasibility and adoption) and clinical efficacy (contraceptive method uptake by women wishing to avoid pregnancy) using a Hybrid Type 2 study design of a family planning program being piloted by the Cervical Cancer Prevention Program in Gabarone, Botswana.

Evaluating the Safety and Efficacy of Long-Acting Injectable Cabotegravir Compared to Daily Oral TDF/FTC for Pre-Exposure Prophylaxis in HIV-Uninfected Women

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

This study will evaluate the safety and efficacy of the long-acting injectable agent cabotegravir (CAB LA) compared to daily oral tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) for pre-exposure prophylaxis (PrEP) in HIV-uninfected women.

NCT ID: NCT03141060 Recruiting - HIV Infections Clinical Trials

Evaluating the Pharmacokinetics, Safety, and Tolerability of Delamanid in Combination With Optimized Multidrug Background Regimen (OBR) for Multidrug-Resistant Tuberculosis (MDR-TB) in HIV-Infected and HIV-Uninfected Children With MDR-TB

Start date: January 30, 2018
Phase: Phase 1/Phase 2
Study type: Interventional

This study will evaluate the pharmacokinetics, safety, and tolerability of the anti-tuberculosis (TB) drug delamanid (DLM) in combination with an optimized multidrug background regimen (OBR) for multidrug-resistant tuberculosis (MDR-TB) in HIV-infected and HIV-uninfected children with MDR-TB.

NCT ID: NCT03088410 Recruiting - Diabetes Mellitus Clinical Trials

Study of HIV-Infected and Uninfected Pregnant Woman/Child Dyads in Gabarone, Botawana

VESTED
Start date: December 12, 2017
Phase: Phase 3
Study type: Interventional

The purpose of this study is to compare the virologic efficacy and safety of three antiretroviral (ARV) regimens in HIV-1-infected pregnant women and to compare the safety of these regimens for their infants.

NCT ID: NCT02803827 Recruiting - 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 Recruiting - HIV Clinical Trials

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

Start date: April 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 Recruiting - 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.
