This research suggests that the RNA and proteins produced by the reservoirs could be behind inflammation, accelerated cardiac disease, frailty, and premature osteoporosis, which can persist in people who are otherwise successfully treated for HIV. Future studies will need to examine these reservoirs in more diverse populations, but this research could lead to the identification of new ways to target these remaining active viruses in people receiving HIV treatment to ensure that the virus does not rebound and to address their potential health consequences.New research has identified the spread of new strains of malaria parasites in Ethiopia that are resistant to current artemisinin-based treatments and indetectable by common diagnostic tests. This discovery follows the recent identification of strains in other regions of Africa that were resistant to either treatment or testing, although the Ethiopia strain is the first identified resistant to both. The spread of these strains could be a major challenge to efforts to eliminate malaria globally. This most recent finding also underscores the urgent need for both close monitoring of the spread of resistance among malaria parasites, as well as development of new therapies and vaccines.Last week, GARDP announced a sublicense agreement with the Indian company Orchid Pharma to manufacture Shionogi’s antibiotic cefiderocol, enabling Orchid to produce the drug more cheaply for low- and middle-income countries in the face of global gaps in access to antibiotics and rising rates of antimicrobial resistance. This agreement builds on a partnership between GARDP, Shionogi, and the Clinton Health Initiative, which granted GARDP the license last year. Cefiderocol is on the World Health Organization’s Model List of Essential Medicines and is considered globally to be an important weapon against difficult-to-treat, multidrug-resistant infections, but it has not yet been made commercially available in the majority of low- and middle-income countries.

The vaccine license was acquired through the Medicines Patent Pool, which also enabled last week additional agreements under C-TAP for a COVID-19 vaccine prototype and a test used to measure COVID-19 antibody levels. While C-TAP was launched at the height of the pandemic to promote technology sharing to improve access, particularly to vaccines, in low-income countries, major pharmaceutical companies have thus far declined to join the initiative.A clinical trial led by researchers at St George’s, University of London found that a higher dose of the antibiotic rifampicin for an abbreviated four-month treatment regimen for tuberculous (TB) was safe with no increases in side effects or toxicities, compared to the standard six months, which is WHO-recommended. The trial took place among adults with newly diagnosed pulmonary tuberculosis in Uganda, Guinea, Peru, Nepal, Botswana, and Pakistan. Experts say shorter treatment regimens will help lower costs and increase patient compliance, which will in turn reduce transmission and the development of resistance to available TB drugs. CSL Sequiris announced that it received an award from the Biomedical Advanced Research and Development Authority (BARDA) to deliver a vaccine for bird flu to the US government, increasing BARDA’s stockpile in case of an outbreak. The company will deliver one bulk lot of the H5N8 A/Astrakhan antigen to the US government, whose development has been supported by BARDA in recent years. The agreement is intended to improve US national vaccine preparedness and is especially significant as bird flu continues to be detected around the world, including a small number of human cases.
