About CTD

Since its first initiation of GCP compliant clinical trial in 2001, the Clinical Trial Directorate (CTD) conducts various drugs, vaccines, and devices trials; as well as Bioequivalence and pharmacovigilance studies. We are devoted to the design, protocol writing, conduct, management, monitoring and reporting of clinical trials for academic and regulatory purposes. Strengthening the local heath innovation and clinical development of traditional medicinal products are areas of potential collaboration for improvement of patient care in the country. The CTD is dedicated for supporting postgraduate studies in clinical research and provide short term training on GCP, Research ethics, GCP monitoring, Methods in Clinical Trial, and other need based trainings. We are also mandated to develop satellite trial sites, support/mentor other clinical trial sites in capacity building, trainings, quality management and community engagement in improving the clinical trial landscape in the country.

The CTD currently has a clinical trial site with phase I trial facilities including study ward, safety clinical laboratory; and acquired experiences in setting up collaborating satellite trial sites in several health care facilities in Addis Ababa and beyond. A state of the art clinical trial site infrastructure with all the facilities for phase I and bioequivalence studies including participant screening facilities, study ward with several beds, study pharmacy, quality trial management, archiving, clinical trial safety laboratory, bio analytical laboratory and emergency facilities is under development within AHRI’s new research complex.

Selected & Featured Clinical Trials, Studies @ CTD

  1. Drugs, Vaccines, Medical Devices and Diagnostic Trials

STREAM stage 2 (Completed): Site PI: Dr. Adamu Bayissa; 2016-2022

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): Site PI: Dr. Tesfamariam Mebrahtu; 2012-2020

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.

bCPAP (Completed): Site PI: Dr. Meseret Gebre, Co-PI: Dr Kassa Haile in collaboration with icddrb, Bangladesh; 2020-2022

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 was 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.

LAMPREG (On-going): Local PIs: Dr Abebe, Genetu, Dr Mekonnen Teferi in collaboration with University of Calgary & Co-PIs at JU & APHI; since 2021

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 from malaria.

ECCP, OCV Effectiveness in real life setting (On-going): Local PI: Dr Mekonnnen Teferi in collaboration with the International Vaccine Institute (IVI); since 2021

The Ethiopian Cholera Control and Prevention (ECCP) project was initiated as a follow-up of our collaboration with the International Vaccine Institute (IVI) on OCV (oral cholera vaccine). It is mainly assessing the effectiveness and impact of OCV in the control and prevention of cholera in real world setting through an enhanced sentinel diarrheal diseases surveillance around Shashemene, Oromia regional state, Ethiopia.

SOLIDARITY Trial and SOLIDARITY trial Plus for the treatment of COVID-19 (Completed) – Country PI & Coordinator: Drs Emawayish Tesema & Mekonnen Teferi in collaboration with site investigators at Eka Kotebe General Hospital and the WHO SOLIDARITY team; 2020-2023

This is part of the WHO initiative of SOLIDARITY Therapeutics groups in search of treatment to  COVID-19 as part of the global 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 Remdesivir against the standard of care was conducted in Ethiopia in collaboration with the Eka Kotebe General Hospital; then with three more products (i.e. Artesunate, Imatinib and Infliximab) that run until the WHO team decided to stop recruitment, March 2023.

Mvent, Clinical Evaluation of Locally made Mechanical ventilator in Ethiopia (Completed): PI:  Dr Kassa Haile and Dr Ananya Abate; 2021-2022

This study was proposed to pilot whether a locally assembled, an automated ambu bag based mechanical ventilator can properly interact and respond to patient’s need. Such need based local innovations were part of the emergency response during the COVID-19 pandemic. Lessons were learnt particularly in the clinical development of locally innovated medical devices.

OCV Bridging trial (Completed): Site PI: Dr Abraham Aseffa and Co-PI: Dr Zenebe Akalu in collaboration with the International Vaccine Institute (IVI); 2013-2014

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

4FDC (Completed): Lcoal PI: Dr Abraham Aseffa; 2006

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

THyB3 (Completed): Site PI: Dr Jemal Hussein in collaboration with SSI, Denmark; 2010

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.

  1. Bioequivalence studies

Lead 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 have experiences with ciprofloxacin and contrimoxazol tablets in a pilot and pivotal studies. 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 as part of the EDCTP supported DPP (Developing Pediatric Primaquine) project.

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. Accordingly, we are currently engaged in development of a full-fledged BE center with clinical and bioanalytical laboratory facilities.      

  1. Others

 Pharmacovigilance studies

The directorate has been part of the 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. In parallel, the performance of Ethiopian active drugs safety monitoring (aDSM) gainst new anti-TB drugs was evaluated.

RER-CTO coordinated by the University of Oslo, and Armauer Hansen Research Institute (AHRI) of Ethiopia, will take the Scientific lead of this research with Dr. Kassa Haile.

Objectives:

  • Reinforce policy and legal framework for clinical trial oversight in Ethiopia, Tanzania and beyond.
  • Improve regulatory and research ethics oversight capacity and capability in Ethiopia, Tanzania and beyond.
  • Strengthen local, regional, and international collaborations and coordination of NECs and NRAs for clinical trial oversight in Ethiopia, Tanzania and beyond.

The three-year project aims to bolster the capacity and capability of national regulatory authorities (NRAs) and national ethics committees (NECs) in Ethiopia and Tanzania. The focus is on improving legal and policy frameworks, enhancing regulatory and research ethics oversight, and fostering stronger collaborations at local, regional, and international levels.

By the end of its term, RER-CTO seeks to set new standards for ethics and regulatory functions in the region, ensuring robust and harmonized clinical trial oversight that aligns with global best practices.
