NCT ID: NCT05057858 Active, not recruiting - HIV Infections Clinical Trials

The Women TDF-FTC Benchmark Study

Start date: April 25, 2022
Phase: Phase 2
Study type: Interventional

The study seeks to define the expected blood levels of pre-exposure prophylaxis (PrEP) medications (tenofovir) for cisgender women taking directly observed oral PrEP therapy to understand the frequency of PrEP dosing associated with HIV protection in cisgender women. Cisgender women will be randomly assigned to receive varying frequency of weekly PrEP doses and followed for up to 16 weeks. The study will also investigate how pregnancy affects the expected blood levels to help define optimal dosing of PrEP for HIV prevention during pregnancy.

NCT ID: NCT05041556 Active, not recruiting - Malaria Clinical Trials

Strengthening the Evidence for Policy on the RTS,S/AS01 Malaria Vaccine

MVPE-CC
Start date: April 1, 2021
Phase:
Study type: Observational

The ongoing Malaria Vaccine Pilot Evaluation (MVPE) is being conducted in Ghana, Malawi and Kenya through community and sentinel hospital surveillance systems and a series of household surveys (to measure vaccine coverage). The Malaria Vaccine Pilot Evaluation-Case Control (MVPE-CC) registered here as observational study is embedded within MVPE comprising case-control studies of clinical and mortality outcomes. Each case will require four controls, and caregiver informed consent will be required prior to study activities. These observational case control studies will measure as complementary information to what is being collected through MVPE: 1. Safety among children who received the malaria vaccine, with focus on cerebral malaria, meningitis and severe malaria 2. The impact of the malaria vaccine on all-cause mortality for boys and girls, AND 3. Promote use of case-control approaches by Expanded Programmes on Immunization (EPI) and malaria control programmes.

The investigators will conduct a Phase III cluster randomized controlled trial (cRCT) to evaluate the effectiveness of the implementation of a data-informed stepped care (DiSC) intervention for HIV treatment management among adolescents living with HIV (ALHIV) in high-volume HIV clinics in Kenya. The DiSC intervention is comprised of a system to assign ALHIV to care based on their health needs and the different levels of care for each assignment group. The primary outcome will be ALHIV retention, and the secondary outcomes will include adherence, viral non-suppression, and receipt of differentiated care among ALHIV.

NCT ID: NCT04966702 Active, not recruiting - Malaria Clinical Trials

Broad One Health Endectocide-based Malaria Intervention in Africa (BOHEMIA)

BOHEMIA
Start date: March 17, 2022
Phase: Phase 3
Study type: Interventional

The BOHEMIA program consists of a combination of studies organized around a central community prevention mass drug administration protocol and four sub-studies (i.e.; social science, entomology, health economics, and environmental), each written as an individual protocol. The protocol is central but used in two separate, individually powered trials in Mozambique and Kenya. The trials have been powered on the efficacy outcome and designed to meet the requirements of WHO´s preferred product characteristics (PPC) for endectocides.

NCT ID: NCT04935879 Active, not recruiting - Sickle Cell Disease Clinical Trials

A Study to Assess the Safety and Efficacy of Inclacumab in Participants With Sickle Cell Disease Experiencing Vaso-occlusive Crises

Start date: October 26, 2021
Phase: Phase 3
Study type: Interventional

This Phase 3 study will assess the safety and efficacy of inclacumab, a P-selectin inhibitor, in reducing the frequency of vaso-occlusive crises (VOCs) in approximately 240 adult and adolescent participants (≥ 12 years of age) with sickle cell disease (SCD). Participants will be randomized to receive inclacumab or placebo.

NCT ID: NCT04904549 Active, not recruiting - COVID-19 Clinical Trials

Study of Monovalent and Bivalent Recombinant Protein Vaccines Against COVID-19 in Adults 18 Years of Age and Older

VAT00008
Start date: May 26, 2021
Phase: Phase 3
Study type: Interventional

The purpose of this Phase III study is to assess the efficacy, safety, and immunogenicity of two CoV2 preS dTM-AS03 vaccines (monovalent and bivalent) as part of primary series vaccinations in a multi-stage approach, as well as a booster injection of a CoV2 preS dTM-AS03 vaccine, in adults 18 years of age and older. A total of approximately 21 046 participants are planned to be enrolled (5080 per study intervention group in Stage 1 and 5443 per study intervention group in Stage 2). Initial, double-blind, primary series study design is planned for 365 days post-last Initial injection (ie, approximately 386 days total) for each participant. Based on decisions of the Study Oversight Group, Stage 1 and Stage 2 participants will be invited to participate in an unblinded Crossover / Booster study design with duration as follows: - For participants who initially received vaccine: 12 months post-booster (ie, approximately 18 to 24 months) - For participants who initially received placebo: ≥ 4 months post-last dose of the primary series + 12 months post-booster (ie, approximately 28 to 34 months) - For participants who do not consent to continue in the unblinded Crossover / Booster part of the study, all study procedures will be stopped and participants will be discontinued from the study.

Hypothesis to be tested: The safety profile and the magnitude and durability of immune responses to the COVID-19 vaccines as well as adverse reactions depend on health conditions, metabolism and microbiomes.

NCT ID: NCT04826094 Active, not recruiting - HIV Infections Clinical Trials

A Study to Assess the Safety and Immune Response to Env-C DNA and Protein Vaccines in Kenya

Start date: March 15, 2021
Phase: Phase 1
Study type: Interventional

This is a study of HIV vaccines. A vaccine is a medical product given to prevent certain diseases. The vaccine may educate the body to form a defensive response to try to prevent the disease from the beginning, or preventing it from taking hold of the body. This defensive response is called the immune response. The experimental vaccines in this study are Env-C Plasmid DNA and HIV Env gp145 C690 protein, given with different adjuvants. An adjuvant is a substance added to vaccines that can help make the vaccine more effective by improving the immune response, or by causing the immune response to last longer than it would without the adjuvant. The adjuvants are mixed with the vaccines and injected into muscle or placed on top of the skin. The HIV vaccines contain a piece of genetic material or a protein copied drom the HIV virus cover (Env), but they do not contain the virus itself. The vaccines cannot cause HIV infection or Acquired Immune Deficiency Syndrome (AIDS). The purpose of this study is to find out if the study vaccines with adjuvants cause side effects and are tolerable, whether humans respond (develop immune responses) to the vaccines, and how ling the effects of the study vaccines last. The study will also compare the effects of the study vaccines with adjuvants and adjuvant patch to those of placebo injections and placebo patch. The placebo will consist of saline (sterile saltwater) and will look like study vaccines, be given in the same way, but will have no active vaccine or adjuvant in it. A total of 126 participants will take part in the study and each will have up to 26 clinic visits and will be followed-up for a total of 108 weeks.
