Long-Term Clinical, Immunologic, and Virologic Profiles of Children Who Received Early Treatment for HIV

Start date: February 2, 2022
Phase:
Study type: Observational

IMPAACT 2028 is an observational prospective study to characterize a cohort of early treated children who may participate in future research related to HIV remission or cure. Up to approximately 250 participants will be in the study for approximately seven years. No intervention is provided in the study.

Protocol RV 583 Multinational Observational Cohort of HIV and Other Infections

MOCHI
Start date: November 5, 2021
Phase:
Study type: Observational

Multinational Observational Cohort of HIV and other Infections (MOCHI). This observational study is to gain information regarding the number of new HIV infections among people who engage in behaviors that make them vulnerable to acquiring HIV across multiple international sites.

NCT ID: NCT05139524 Recruiting - Rift Valley Fever Clinical Trials

RVF and Other Emerging Infectious Diseases in East and Central Africa

Start date: October 8, 2021
Phase:
Study type: Observational

Rift Valley fever (RVF), a disease transmitted from livestock (cattle, sheep, goats, camels) to humans more commonly occurs in the East and Central Africa (ECA) regions where more than 15 major epidemics affecting more than one country have been reported over the past 50 years. Within the region, there are specific areas, referred to as hotspots, which support RVF virus maintenance via low-level virus circulation between animals, humans, and mosquitoes. Most outbreaks originate from these hotspots. Our goal is to conduct studies in RVF hotspots in four ECA countries, Kenya, Uganda, Tanzania, and Democratic Republic of Congo (DRC) to determine the burden of RVF disease among humans, wildlife and livestock during inter-epidemic periods (IEPs) and discover circulation of undetected infectious diseases. This information is important for use in developing an early warning system and possibly a vaccination strategy. The study will take place in Uganda, Kenya, Tanzania and Democratic Republic of Congo

NCT ID: NCT05075824 Recruiting - Sickle Cell Disease Clinical Trials

A Study Evaluating the Efficacy, Safety, Pharmacokinetics, and Pharmacodynamics of Crovalimab as Adjunct Treatment in Prevention of Vaso-Occlusive Episodes (VOE) in Sickle Cell Disease (SCD)

CROSSWALK-c
Start date: March 9, 2022
Phase: Phase 2
Study type: Interventional

This study is designed to evaluate the efficacy, safety and pharmacokinetics of crovalimab compared with placebo as adjunct therapy in the prevention of VOEs in participants with SCD.

NCT ID: NCT05073003 Recruiting - Diarrhoea Clinical Trials

A Study on the Safety and Immune Responses to the GVGH altSonflex1-2-3 Vaccine Against Shigellosis in Adults, Children, and Infants

Start date: October 6, 2021
Phase: Phase 1/Phase 2
Study type: Interventional

The aim of the current clinical study is to evaluate, for the first time in humans (FTIH), the safety and immunogenicity of the altSonflex1-2-3 candidate vaccine against S. sonnei and S. flexneri serotypes 1b, 2a, and 3a. The vaccine will be first administered in adults 18 to 50 years of age in Europe. Subsequently, the vaccine will be administered to a shigellosis-endemic population in Africa, first in adults 18 to 50 years of age, then in children 24 to 59 months of age, and finally in infants 9 months of age. Infants will also receive a third vaccination. Three different doses of the vaccine [low (Dose A), medium (Dose B), and high (Dose C) amounts of antigen] will be evaluated using an age de-escalation approach (from least vulnerable adult population to most vulnerable paediatric population). The results of this study will allow the selection of the most appropriate dose for further vaccine development in infants 9 months of age, which is the main target age group for this vaccine.

NCT ID: NCT05048472 Recruiting - HIV Clinical Trials

East Africa Point of Care Viral Load Study

EAPoC-VL
Start date: August 19, 2022
Phase: N/A
Study type: Interventional

The purpose of the project is to examine the feasibility, acceptability, and effectiveness of using point of care viral load (PoC VL) monitoring to improve viral load suppression among children and adolescents (age ≤19 years) living with HIV in Kenya, Rwanda, Tanzania and Uganda.

NCT ID: NCT05044962 Recruiting - HIV Infections Clinical Trials

Kuwa Free! - Live Free!

Start date: November 26, 2021
Phase: N/A
Study type: Interventional

The study investigators are conducting foundational pharmacokinetic (PK) and qualitative studies, among 15-24 years old (inclusive) adolescent girls and young women living with HIV (AGYWLHIV) already on oral antiretroviral therapy (ART) and virally suppressed, leading up to a hybrid type I effectiveness-implementation trial randomizing individual AGYWLHIV to receive long-acting (LA) injectable cabotegravir/rilpivirine vs. standard of care within one of Kenya's largest HIV treatment programs. The PK and qualitative studies will investigate potential issues arising from co-delivery and guide delivery of the effectiveness-implementation trial. The PK and qualitative studies will largely be conducted with a sentinel cohort of AGYWLHIV. Learning from this early LA ART use, the investigators will refine the procedures in the LA ART hybrid trial.

NCT ID: NCT05031780 Recruiting - Sickle Cell Disease Clinical Trials

A Study Evaluating the Efficacy and Safety of Mitapivat (AG-348) in Participants With Sickle Cell Disease (RISE UP)

Start date: February 11, 2022
Phase: Phase 2/Phase 3
Study type: Interventional

This clinical trial is a Phase 2/3 study that will determine the recommended dose of mitapivat and evaluate the efficacy and safety of mitapivat in sickle cell disease by testing how well mitapivat works compared to placebo to increase the amount of hemoglobin in the blood and to reduce or prevent the occurrence of sickle cell pain crises. In addition, the long-term effect of mitapivat on efficacy and safety will be explored in an open-label extension portion.

NCT ID: NCT05007821 Recruiting - Tuberculosis Clinical Trials

Linezolid Dosing Strategies in Drug-Resistant TB

Start date: August 11, 2022
Phase: Phase 2
Study type: Interventional

The purpose of the study is to evaluate the efficacy (how well the medicines work) and tolerability (whether participants stop treatment because of side effects from a drug or treatment) of an anti-TB treatment regimen that compares two doses of linezolid (LZD), combined with bedaquiline (BDQ), delamanid (DLM), and clofazimine (CFZ). This study will also measure the level of these medicines in the participants' blood.
