About to start the session about the study that shows that High-dose rifapentine with moxifloxacin can shorten treatment time by a third for people with pulmonary #TB#UnionConf
#s31tb is the largest drug-sensitive #tb treatment trial in decades. It tested two arms vs. control aiming to shorten treatment to 4 months:
👉🏽substituting rifampicin with high-dose of rifapentine, &
👉🏽same + ethambutol for moxifloxacin
🧫Innovation: the #S31TB enrolled 2,500 participants in 13 countries and included adolescents over 12, people living with HIV and people with cavitary #TB.
🤝Collaboration! #S31TB was an effort by two US-funded research networks: TBTC (at @CDC_TB) and @ACTGNetwork (at @NIH)
📣 #S31TB The arm testing high dose rifapentine and moxifloxacin shows noninferiority.
Aka: Finally: a safe, effective and shorter #tuberculosis treatment! People will be cured in four months instead of six!
This major scientific advance is thanks to public 💵, a public good!
Yes!
We finally have a safe, effective and shorter #tuberculosis treatment! People will be cured in four months instead of six!
📣 The new 4-month regimen is safe and effective in all studied groups.
We need to move forward and make the new treatment accessible as soon as possible – first in the 13 countries involved in #S31TB 🌍
Community engagement 💪🏽 was paramount in #S31TB design and implementation. High retention and adherence in all arms
👩🏽🔬Researchers adapted the design of this study to meet the needs and requests of #TB-affected communities in addition to relevant response to scientific questions
📣 The #tuberculosis 4-month regimen benefits patients, health providers and health systems.
👏🏽@WHO Guidelines will need to adapt to this new era of treatment for sensitive pulmonary 🫁 TB.
➡️ Dr. Grace Muzanye, Senior Clinical Coordinator (Kampala), summarizes perfectly the importance of this new 4-month regimen with this slide.
Dr. Payam Nahid explains the design of the trial: #S31TB was a three-arm trial of:
2HPZE/2HP (4 months)
2HPZM/2HPM (4 months)
2HRZE/4HR (6 months) – control arm
It was open label, because with rifampicin is better to take without food whereas rifapentine is better with food🥑
Dorothy Namutamba answers about the collaboration communities- researchers.
One of community requests was to lower CD4 count limit to 100 for #PLWHIV to ensure we had enough data for this group.
