Mpox Treatment Rethink: What the STOMP Trial Means for Future Outbreak Responses

Recent findings published in the Recent England Journal of Medicine on February 26, 2026, are prompting a reassessment of mpox treatment strategies. The STOMP (Study of Tecovirimat for Mpox) trial, detailed in the journal’s Volume 394, Issue 9, revealed that tecovirimat, previously considered a promising therapeutic, did not significantly improve outcomes for individuals with mpox.

The STOMP Trial: A Turning Point in Mpox Research

The STOMP trial, conducted by the ACTG (AIDS Clinical Trials Group), enrolled participants until December 2024. An interim analysis revealed that tecovirimat didn’t reduce the time it took for mpox lesions to resolve, nor did it alleviate pain in outpatient adults infected with clade II mpox. This outcome challenges prior expectations within the scientific community.

“This publication reminds us of the importance of randomized clinical trials,” stated ACTG Chair Joseph J. Eron, M.D., of the University of North Carolina. “Tecovirimat was widely expected by the scientific community to be an effective treatment for mpox and it was only through STOMP that we were able to conclusively demonstrate that it is not.”

Implications for Global Health Security

The STOMP results underscore a critical require for robust, randomized controlled trials to identify effective treatments for mpox and other orthopoxviruses. Mpox remains a global health concern, and relying on anticipated efficacy without rigorous testing can lead to suboptimal patient care and hinder outbreak control.

The findings highlight the importance of proactive research investment in infectious disease therapeutics. Waiting for an outbreak to begin before initiating clinical trials can delay the availability of effective treatments, potentially exacerbating the impact of future epidemics.

Beyond Tecovirimat: The Search for Effective Mpox Therapies

While tecovirimat didn’t meet expectations, research continues on other potential treatments. Further investigation into antiviral medications, immunomodulators, and supportive care strategies is crucial. The development of novel therapeutics tailored to different mpox clades is likewise a priority.

The STOMP trial serves as a valuable lesson in the complexities of infectious disease research. It emphasizes the need for adaptive trial designs that can quickly evaluate promising interventions and adjust strategies based on emerging data.

FAQ: Mpox Treatment and the STOMP Trial

  • What did the STOMP trial locate? The STOMP trial found that tecovirimat did not improve mpox resolution or reduce pain in outpatient adults.
  • Why is this important? This finding challenges previous assumptions about tecovirimat’s effectiveness and highlights the need for further research.
  • What are the next steps in mpox research? Researchers are continuing to investigate other potential treatments and adaptive trial designs.

Pro Tip: Stay informed about the latest mpox research by regularly consulting reputable sources like the New England Journal of Medicine and the World Health Organization.
