In a recent clinical trial conducted in the Democratic Republic of the Congo , the antiviral drug tecovirimat , commonly used to treat mpox , did not accelerate healing for individuals infected with a concerning strain of the monkeypox virus known as clade I. This strain has been spreading across Africa and is considered more lethal than the one responsible for a global mpox outbreak in 2022 , designated as clade II . The World Health Organization ( WHO ) declared a public health emergency of international concern due to the spread of clade I mpox in the DRC and neighboring countries . Sweden also reported its first case of clade Ib , a variant of clade I , which scientists believe can spread through sexual contact.
Early results from the clinical trial showed that tecovirimat did not reduce the duration of mpox symptoms compared to a placebo . However , the mortality rate among participants was lower than the overall mortality rate typically reported in the DRC . The study highlighted the importance of high - quality medical care in improving outcomes for individuals with mpox . While the results were disappointing , there is hope that with appropriate resources and support , recovery rates for clade I mpox can be increased . The manufacturer of tecovirimat , SIGA Technologies , Inc. , suggested that certain groups , such as those with severe disease or early treatment , may benefit from the drug.
Additional analysis of the trial data is ongoing to identify specific subgroups that may benefit from tecovirimat treatment , such as individuals with advanced HIV . The results of the trial do not change the current response plan for mpox outbreaks in Central Africa , which includes enhancing surveillance , increasing laboratory testing , and securing additional vaccine doses . While tecovirimat did not show significant efficacy in this trial , ongoing studies are evaluating its potential in different populations with mpox . The importance of conducting robust clinical trials in endemic settings like the DRC was underscored by the study 's findings.
In response to the ongoing spread of mpox in Central Africa , research efforts continue to develop safe and effective interventions , including treatments and vaccines . The National Institutes of Health ( NIH ) and the Democratic Republic of the Congo 's Institut National de Recherche Biomédicale ( INRB ) collaborated on the PALM007 trial to evaluate tecovirimat for mpox treatment . While the initial results were not as expected , they provide valuable insights into managing mpox - related disease and the importance of supportive care in improving outcomes . Ongoing studies , such as the STOMP trial , will further investigate the safety and efficacy of tecovirimat in different populations affected by mpox.
