A new study quantifying the high risk of Plasmodium vivax parasitaemia after treatment of Plasmodium falciparum malaria aims to identify populations in which a policy of universal radical cure, combining artemisinin-based combination therapy with a hypnozoitocidal antimalarial drug, would be most beneficial.
In the next few months, the first Phase 3 COVID-19 vaccine trials \u2013 the majority of them in upper-middle or high-income countries and in specific target populations like young adults \u2013 will report their results. How relevant will their study results be for low-resource settings?
The University of Oxford has awarded CTMGH two new Professors. Elisabeth Ashley - UK-trained physician who specialises in infectious diseases and medical microbiology & virology, and Director of the Lao-Oxford-Mahosot Hospital-Wellcome Trust Research Unit (LOMWRU) in Lao PDR since 2019, Liz is conferred the title of Professor of Tropical Medicine. Stuart Blacksell - Senior Research Scientist based at the Mahidol-Oxford Tropical Medicine Research Unit (MORU) in Thailand, Stuart is conferred the title of Professor of Tropical Microbiology.
We are pleased to announce that Prof Joel Tarning has been awarded the biennial Grahame-Smith Prize by the British Pharmacological Society for outstanding contributions to clinical pharmacology. Joel has headed MORU's Clinical Pharmacology Department since 2012. Since then, the Department has grown into large, productive group that conducts laboratory- and computer-based pharmacology research.
Oxford is world-famous for research excellence and home to some of the most talented people from across the globe. To showcase our global research, the University launched a Global Research Map, highlighting areas of research we are conducting overseas.
The University of Oxford, MORU, the University of Cape Town, the Thai Ministry of Public Health, and UNICEF Thailand worked together to promote lifelong health and well-being, and prevent violence against children. Led by Amalee McCoy from MORU Department of Bioethics & Engagement, this project involved the cultural adaptation and testing of an evidence-based parenting intervention for low-income families with children aged 2-9 living in Udon Thani, Thailand.
MORU\u2019s Mo Yin and MOCRU\u2019s Myo Maung Maung Swe were awarded a prize by the NDM\u2019s Graduate Studies Committee. Very competitive awards, the prizes are given annually to current or recently graduated students of NDM supervisors on the basis of their publication record, the impact and novelty of their research, references, and research within their department.
A series of articles that set out to explore the global distribution of infections that cause non-malarial febrile illness has been published in BMC Medicine. The series brings together the results of large-scale systematic reviews of the causes of fever in Africa, Latin America, and Southern and South-Eastern Asia, and has helped identify major knowledge gaps, geographical differences, priority areas for diagnostics research and development, and enabled the most comprehensive systematic review of literature to date.
Research Malaria Microscopy Standards (ReMMS) applicable to malaria clinical research studies have been published in Malaria Journal. The paper describes the rationale for proposed standards to prepare, stain and examine blood films for malaria parasites.
As the world waits impatiently for a COVID-19 vaccine, an exhaustive review of hydroxychloroquine and chloroquine pharmacology suggests that the doses used in COVID-19 prevention trials are safe, say University of Oxford affiliated researchers in a study published in PLoS Medicine.
Hydroxychloroquine could still prevent COVID-19 and save tens of thousands of lives around the world, say leading scientific researchers. While it doesn\u2019t work in treatment of hospitalised patients, it could still prevent infections. However, fraudulent data, unjustified extrapolation and exaggerated safety concerns together with intense politicisation and negative publicity may stop COPCOV, the only large, global clinical trial testing hydroxychloroquine in COVID-19 prevention, from ever finding out.
Blog by Professor Christiane Dolecek. Antimicrobial resistance is a critical problem in enteric fever. Drug-resistant infections can have severe consequences, and slowing their spread requires our urgent attention. The most important intervention is to reduce the number of infections; vaccines are a critical tool, alongside surveillance and diagnosis. To achieve this control, strong partnerships between WHO, governments, NGOs, academia, private sector and communities are needed.
The results of the University of Oxford\u2019s Recognition of Distinction exercise for Associate Professor and University Research Lecturer are in, and I am delighted to announce that the University has conferred titles on the following MORU staff:
The UK regulator MHRA announced on 26 June that it would again permit recruitment to the COPCOV COVID-19 prevention clinical trial. The MHRA decision came 5 weeks after it reacted immediately to the now-discredited paper published in The Lancet suggesting harms with hydroxychloroquine, and paused recruitment of UK participants. But The Lancet paper was based on fabricated data and was swiftly retracted. After this interruption, recruitment around the globe to COPCOV can now resume.
Paper by NJ White et al, PLoS Medicine, in press. Using available pharmacokinetic information from healthy volunteers, the treatment of malaria, the chronic treatment of rheumatological conditions and the toxicokinetics of chloroquine in self-poisoning, the authors predict exposures and safety margins in the high dose chloroquine and hydroxychloroquine COVID-19 prevention and treatment regimens currently under evaluation. These regimens are predicted to have reasonable safety margins. Large, well conducted randomised clinical trials with appropriate monitoring are required to determine if chloroquine and hydroxychloroquine have preventive or treatment efficacy in COVID-19 and acceptable safety. Current recommendations for their use outside of clinical trials are not justified at this time.
On 4 June 2020, after a week of increasing scientific concern and scrutiny, first The Lancet, then the New England Journal of Medicine, retracted studies that were based on inaccessible data. The studies have been extremely damaging to chloroquine and hydroxychloroquine COVID-19 clinical trials around the globe. MORU researchers played a key role in bringing this scandal to light, whose consequences continue to play out.
On 4 June 2020, after a week of increasing scientific concern and scrutiny, first The Lancet, then a little over an hour later the New England Journal of Medicine, retracted studies that were based on inaccessible data, provided by the Surgisphere corporation. The studies have been extremely damaging to chloroquine and hydroxychloroquine COVID-19 clinical trials around the globe. Here is MORU\u2019s statement in response to these events.
The results of Mehra et al in The Lancet have had a considerable impact on public health practice and research, halted trials and caused considerable concern to participants and patients enrolled in randomised controlled trials (RCTs). This has led many researchers around the world to scrutinise in detail the publication and outline their concerns in this letter to Richard Horton, editor of The Lancet.
We received notice from the UK's MHRA (Medicines and Healthcare Products Regulatory Agency) to pause for now new enrolment into our COPCOV study. We responded promptly to the MHRA, addressing their concerns in detail and await their decision. For now, COPCOV study enrolment is paused around the globe. The safety of our participants is our first priority, as is preventing illness in front-line healthcare workers.
A global study to test if either chloroquine or hydroxychloroquine can prevent COVID-19 in vital frontline healthcare workers will open to UK participants at hospital sites in Brighton and Oxford today.
The SEBCOV study aims to produce evidence to inform public health measures such as communications, quarantine, self-isolation, social distancing, and travel restrictions for the COVID-19 pandemic. This study is run in four countries: UK, Thailand, Italy and Malaysia.
The Epidemiology Department of MORU and National Malaria Control Programme, Cambodia (CNM) have begun to implement a study to assess the efficacy of prophylaxis with artemether-lumefantrine (PAL) against forest malaria in Siem Pang District, north-eastern Cambodia bordering Laos.
The impact of COVID-19 is quite evident at present \u2013 entire countries and cities are under lockdown, offices and industries shut and academia at a standstill. However, many people in Bangladesh remain unaware or indifferent to the warnings and safety protocols that ought to be followed to stop COVID-19\u2019s spread. Since enforcing social distancing in a densely populated country like Bangladesh is very challenging, making people aware and maintenance of hygiene are the main means to stop the spread of COVID-19.
Less than a month after it was announced, the MORU-led COPCOV study has made quick progress and expects to begin enrolling participants by the end of April.
There are currently no proven vaccines or drugs to prevent COVID-19. In this BBC World News interview, MORU\u2019s Prof Sir Nick White explains why the only way to find out if chloroquine and hydroxychloriquine work against COVID-19 is via randomised, clinical trials and how the hype over chloroquine negatively affects people with lupus and rheumatoid arthritis.
Researchers at MORU and two institutions in the US (University of Washington and La Jolla Institute for Immunology) receive grants from the COVID-19 Therapeutics Accelerator, a large-scale initiative launched by the Bill & Melinda Gates Foundation, Wellcome, and Mastercard to speed the development of and access to therapies for COVID-19.
Adding a third anti-malaria drug to current artemisinin-combination therapies (ACTs) provides effective treatment against multidrug-resistant falciparum malaria in Southeast Asia, say Oxford researchers in a study in The Lancet. Using TACTs should extend current malaria drugs so drug-resistant malaria doesn't kill millions more and derail hopes of controlling and eliminating malaria.
When we are ill, we expect our medicines to work as intended. But what if they do not contain the ingredients listed on the packaging? The Pharmacide Arts exhibition \u201cWhat\u2019s in your medicines?\u201d showcases the original artwork of 11 South East Asian artists. The exhibition is open to the public from 26th-28th January 2020 at the Mandarin Hotel, Bangkok, from 10 am \u2013 5 pm.
A new study conducted by Christiane Dolecek and colleagues analysed data on antimicrobial resistance of the bacteria Salmonella Typhi and Salmonella Paratyphi, from around the globe, spanning the time from 1990 to 2018. The study highlights the impact of drug resistance and the urgent need for interventions.
Professor Joel Tarning received a Bailey K. Ashford Medal at the ASTMH 2019 Conference. The medal is awarded annually for distinguished work in tropical medicine by an early- to mid-career ASMTH member. Joel is Head of Clinical Pharmacology at MORU and his work focuses on applying pharmacokinetic-phamacodynamic modelling to optimise antimalarial drug therapies, in particular for at-risk groups such as malnourished children and pregnant women.
Oxford Medical Sciences Divisional Panel has conferred the title of Professor on three members of our Centre. Ben Cooper - Professor of Epidemiology, Sassy Molyneux - Professor of Global Health and Piero Olliaro - Professor of Poverty Related Infectious Diseases were awarded these titles in recognition of their distinction in their respective fields and contributions to the research, teaching and administration of the Department and we congratulate them on their success!
An individual patient data meta-analysis of 2,017 patients from 19 studies has found a high risk of recurrence following treatment of P. vivax malaria with artemether-lumefantrine (AL) and dihydroartemisinin-piperaquine (DP) unless they are co-administered with primaquine. The research supports recommendations that these artemisinin-based combination therapies (ACT) should be combined with primaquine.
MORU and SMRU were delighted and honoured to host the University of Oxford Vice-Chancellor Prof Louise Richardson and her party during her visit to Thailand on 1-4 September. Accompanying the Vice-Chancellor were Jeremy Woodall (Director of Development (Asia)), Frewyeni Kidane (Fundraiser for Southeast Asia), Cher Wu (Asia Development office) and Ed Gibbs (NDM Director of Finance and Operations).
In partnership with the Wellcome Innovations Flagship Programme, MORU launched its Critical Care Asia Network project with its first investigators\u2019 meeting on 19-20 Aug in Bangkok. The project will establish an Asian ICU network across 42 ICUs in nine countries and implement a setting-adapted electronic registry.
Two researchers from the Centre for Tropical Medicine and Global Health were awarded medals by the Royal Society of Tropical Medicine and Hygiene at the 2019 European Congress on Tropical Medicine and International Health. Professor David Warrell was awarded the Sir Patrick Manson Medal, and Dr Samson Kinyanjui the Chalmers Medal.
MORU researchers have found that severe malnutrition is associated with lower exposure to the antimalarial drug lumefantrine in children treated with artemether-lumefantrine, the most common treatment for uncomplicated falciparum malaria. The study, which is the first to specifically address this, calls urgently for further research into optimised dosing regimens for undernourished children.
A rapidly evolving multi-drug resistant lineage of P. falciparum malaria parasites continues to spread in South East Asia, leading to alarmingly high treatment failure rates in Cambodia, Thailand and Vietnam for DHA-piperaquine, one of the world\u2019s most important anti-malaria drugs.
A large clinical trial in Africa and Asia has shown that a 7 day course of high dose primaquine, a drug used to treat P. vivax malaria, is well tolerated and just as effective as the current standard 14 day regimen, according to a study published this week in The Lancet. These findings have important implications for the treatment and elimination of vivax malaria in the Asia Pacific.
A project using drama that engages with village communities in Cambodia, led by Professor Phaik Yeong Cheah of the Mahidol Oxford Tropical Medicine Research Unit and Nuffield Department of Medicine, has won a Project award in this year\u2019s Vice-Chancellor\u2019s Public Engagement with Research Awards. The project also won the Vice-Chancellor\u2019s Choice Award for Public Engagement with Research.
This 5-day course is aimed at participants with a basic understanding of infectious disease modelling and an aptitude for the R programming language. On completion participants will be able to write and analyse the dynamics of a simple mathematical model and use it to consider cost and intervention scenarios. September 23-27 at St Anne\u2019s College, Oxford
