At a first for South Africa, the SACRA clinical trials capacity-building workshop with government, research institutions, and industry, were from the left: Dr Nathaniel Mofolo, Dr Rita Nathan, Dr Mojalefa Maseloa (Head: Clinical Services in the Clinical Unit at the Universitas Hospital) and Sue Baily (Site Management Head at IQVIA).

Whether it is to treat the flu or a more serious illness, all medicines go through a very costly and lengthy research process before being approved for prescription to patients. The cumulative time from the beginning of trials to marketing approval has increased over the past ten years. 

According to Dr Vathi Papu-Zamxaka from the South African Clinical Research Association (SACRA), South Africans would not have had access to safe and effective medicines, had it not been for the intensive research conducted on new medicines. 

On 7 November 2019, a group of 115 delegates representing the Free State Department of Health, the UFS, private research sites, and the pharmaceutical industry met at FARMOVS on the Bloemfontein Campus of the University of the Free State (UFS) for the SACRA clinical trials capacity-building workshop.

2,1 billion dollars to develop one successful drug

Dr Michelle Middle, Chief Medical Officer at FARMOVS, provided some interesting stats on the process for drugs to hit the shelves: “One out of 10 drugs entering human research will be approved. The cost of development of one successful drug is approximately 2,1 billion dollars. And the time to develop a drug, from submission of the Investigational New Drug Application (IND) to approval by the Food and Drug Administration (FDA), is between 12 and 15 years.”

Dr Middle stated that drug development is one of the most regulated processes, with ethics and patient safety governing the undertaking. “With SAHPRA (South African Health Products Regulatory Agency) having some of the strictest regulations in the world, South Africa has a good history of running trials.  In addition, fast growth is expected for the pharmaceutical market on the African continent, necessitating the need for increased clinical trials on this continent,” she said. 

Very few clinical trials hosted in South Africa 

Although Africa has the broadest genetic variability of all human populations and carries 17% of the global population, very few clinical trials are hosted on the continent. Globally, there are currently approximately 322 000 clinical trials being actively conducted, of which only 1 700 are conducted in Africa, i.e. less than 3%.  Even worse, only 304 of the 1 700 trials running in Africa are conducted in South Africa.  There is thus a critical need for South Africa as a country to market itself as a clinical trial destination and to attract more trials to the country.

South Africa’s competitive edge lies in being known for its ICH (International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use)-compliant top-quality research, racial and genetic diverse trial participants, good medical infrastructure and expertise, and the good reputation of the regulator (SAHPRA). “There are, however, a need for transformation and capacity building in clinical research in the country,” said Dr Middle. 

Dr Rita Nathan, Head of Clinical Services in the Clinical Department at the Universitas Hospital, who was representing government at the workshop, is looking to strengthen clinical trials across government and industry by focusing on, among others, funding models, operations management, and service delivery. 

From the UFS Faculty of Health Sciences, Dr Nathaniel Mofolo, Head of the School of Clinical Medicine, said collaboration between stakeholders is important. “This initiative is giving direction to the UFS vision of being a research-led university.” 

Other topics discussed at the workshop include the clinical trials landscape, how clinical trials work, the patient factor, ethics in clinical trials, and the economic aspect of clinical trials.

Mathematical methods used to detect and classify breast cancer masses

Examples of Acho’s breast mass
segmentation identification

Breast cancer is the leading cause of female mortality in developing countries. According to the World Health Organization (WHO), the low survival rates in developing countries are mainly due to the lack of early detection and adequate diagnosis programs.

Seeing the picture more clearly

Susan Acho from the University of the Free State’s Department of Medical Physics, breast cancer research focuses on using mathematical methods to delineate and classify breast masses. Advancements in medical research have led to remarkable progress in breast cancer detection, however, according to Acho, the methods of diagnosis currently available commercially, lack a detailed finesse in accurately identifying the boundaries of breast mass lesions.

Inspiration drawn from pioneer

Drawing inspiration from the Mammography Computer Aided Diagnosis Development and Implementation (CAADI) project, which was the brainchild Prof William Rae, Head of the department of Medical Physics, Acho’s MMedSc thesis titled ‘Segmentation and Quantitative Characterisation of Breast Masses Imaged using Digital Mammography’ investigates classical segmentation algorithms, texture features and classification of breast masses in mammography. It is a rare research topic in South Africa.

 Characterisation of breast masses, involves delineating and analysing the breast mass region on a mammogram in order to determine its shape, margin and texture composition. Computer-aided diagnosis (CAD) program detects the outline of the mass lesion, and uses this information together with its texture features to determine the clinical traits of the mass. CAD programs mark suspicious areas for second look or areas on a mammogram that the radiologist might have overlooked. It can act as an independent double reader of a mammogram in institutions where there is a shortage of trained mammogram readers. 

Light at the end of the tunnel

Breast cancer is one of the most common malignancies among females in South Africa. “The challenge is being able to apply these mathematical methods in the medical field to help find solutions to specific medical problems, and that’s what I hope my research will do,” she says.

By using mathematics, physics and digital imaging to understand breast masses on mammograms, her research bridges the gap between these fields to provide algorithms which are applicable in medical image interpretation.
