Selected & Featured Clinical Trials/Studies @ CTD

1. Drugs Trial

STREAM stage 2 (Ongoing): Led by Dr. Adamu Bayissa

The Evaluation of Standardized Treatment Regimen of Anti-TB drugs for patients with MDR TB (STREAM II ) is an international multicenter randomized controlled phase III trial with a non-inferiority design comparing all oral MDR TB drugs against injectable regimen.

It is sponsored by Vital Strategies (the UNION) and funded by USAID and Janssen Pvt.

STREAM stage 1 (Completed): Led by Dr. Tesfamariam Mebrahtu

The Evaluation of Standardized Treatment Regimen of Anti-TB drugs for patients with MDR TB (STREAM II ) is an international multicenter randomized controlled phase III trial with a non-inferiority design comparing a 9 months regimen against the 18-24 months WHO regimen for the treatment of MDR TB patients. It proved the non-inferiority of the shorted regimen and was endorsed by WHO as standard of care in the management of MDRTB patients.

It is sponsored by Vital Strategies (the UNION) and funded by USAID.

SOLIDARITY trial for the treatment of COVID-19 (on-going) – Led by Drs Mekonnen Teferi & Emawayish Tesema in collaboration with site investigators

This is part of the WHO initiative of SOLIDARITY for enhancing innovation to drugs, vaccines and diagnostics against COVID-19 as part of the public health response to the pandemic. The therapeutics group was initiated with testing re-purposed and new drugs for the treatment of COVID-19 during the earliest period of the pandemic, March 2020. Ethiopia joined the initiative later in October through the co-sponsorship of the MOH where CTD of AHRI lead the trial in Ethiopia. Therefore, the first round of testing was conducted in Ethiopia in collaboration with the Eka Kotebe General Hospital using Remdesivir. Currently data cleaning and analysis is on-going pending protocol amendment with three new products.

4FDC (Completed): Led by Dr Abraham Aseffa

Efficacy and Safety of ‘Fixed Dose’ versus ‘Loose’ Drug Regimens for Treatment of Pulmonary Tuberculosis in Two High TB-Burden African Countries: A Randomized Controlled Trial

2. Vaccine Trials

OCV Bridging trial (Completed): Led by Drs Abraham Aseffa and Zenebe Akalu

Randomized, Placebo-Controlled Trial Evaluating Safety and Immunogenicity of the Killed, Bivalent, Whole-Cell Oral Cholera Vaccine in Ethiopia. (Completed in 2014)

THyB3 (Completed): Led by Dr Jemal Hussein

A phase I, open-label trial on the safety and immunogenicity of the adjuvanted tuberculosis subunit vaccine H1/IC31® in people living in a TB-endemic area. (completed in 2010)

3. Device Trials

bCPAP (Ongoing): Led by: Dr. Meseret Gebre

Pneumonia is the leading cause of under-five mortality in Ethiopia. Different studies have shown the positive impact of providing oxygen therapy via bubble CPAP for hypoxemic children. However, operational challenges related to introduction and clinical use of bubble CPAP essentially requires further evaluation.

The aim of BCPAP clinical trial is to evaluate the feasibility and acceptability of bubble CPAP in treating childhood pneumonia initially in two tertiaries followed by two district hospitals (stages 1&2) and finally to assess the effectiveness of bubble CPAP in reducing death and/or treatment failure in children with severe pneumonia in stage 3 compared with the WHO standard low-flow oxygen therapy among children hospitalized with severe pneumonia in Ethiopia.

Mvent (Upcoming): Led by Dr Kassa Haile

Clinical Evaluation of Locally made Mechanical ventilator in Ethiopia.

This project is currently under review for approval from ECs and regulatory bodies.

4. Diagnostic Trials

LAMPREG (Upcoming): Led by Drs Rediet Fikru & Zelealem Mekonnen (PI- Dr Abebe Genetu)

LAMPREG is a pragmatic randomized control diagnostic trial which will be conducted in pregnant mothers at six sites in Ethiopia. First and second trimester pregnant women will be included in the study and individually randomized to either standard of care or enhanced cased detection arms using LAMP for malaria. In this study, we propose that the use of a highly sensitive LAMP technique will enable us to detect more asymptomatic Plasmodium infections in pregnant women. This consequently results in early treatment of the pregnant mothers and may avert maternal and fetal morbidity and mortality. This project is currently under review for approval from relevant bodies.

5. Bioequivalence studies

Led by Dr Mekonnen Teferi

The CTD took the national initiative for the conduct of the first BE study in Ethiopia in collaboration with the Regional Bioequivalence Center in Addis Ababa in 2014. Since then, we conducted two pilot studies and one pivotal study for WHO pre-qualification. Our site had a pre-inspection experience with WHO auditors in 2015. Currently the site is working for WHO pre-qualification submission of a new pediatric formulation of primaquine in collaboration with different partners abroad.

The BE center at AHRI is part of the national capacity building effort by the MOH in ensuring the safety and efficacy of generic products in Ethiopia and beyond.

6. Pharmacovigilance studies

Led by Dr Mekonnen Teferi

The directorate currently hosting a consortium project on strengthening pharmacovigilance (PV) system in Africa called PAVIA. This is a kind of platform that may facilitate capacity building for monitoring safety of post-licensure and pre-maturely approved new products such as anti-TB drugs in Africa. Therefore, the project is implemented in collaboration with the Ethiopian Food and Drugs Authority and the national TB program for strengthening the PV system through training, supportive supervision of MDRTB TICs and analysis of safety reports. 

PAVIA is a platform for strengthening safety monitoring at the regulatory and post marketing safety investigations by medical research institutes with special interest on newly introduced medicinal products.

7. Social Science Studies

SaLTs (Ongoing): Led by Dr Kassa Haile

Undergoing program evaluation to review the outcomes of the national safe surgery strategy, the changes brought about through the SaLTS flag-ship program, and also document the lessons learned in public and private health facilities in Ethiopia.

ACESS Africa (Ongoing): Led by Yemiserach Zewde

Improving post-trial access arrangements in clinical trials in Sub-Saharan Africa; Acess AFRICA Study.
