A Campaign to Rally Energy, Funding, and Political Will to End TB

Tuberculosis (TB) is one of the world’s deadliest infectious diseases, but has long been neglected by governments, funders and global health actors. For more than a half century, we’ve been fighting TB with the same outdated resources, strategies and long, toxic courses of treatment that left patients with lasting side effects.

Thanks to decades of investment in scientific research, we now have newer, safer, and more effective regimens – but very few people around the world have access to them. The 1/4/6×24 Campaign aims to change that. The Campaign’s name comes from its central demand: that countries and other duty bearers take action to implement the shortest available regimens – one month or once-weekly for TB prevention, four months for drug-sensitive TB, and six months for drug-resistant TB — by the end of 2024.

= One-month and once-weekly TB preventive treatments, 1HP and 3HP (one month of daily, or three months of weekly isoniazid and rifapentine).

= Four-month treatment regimens for drug-sensitive TB, 4HPMZ for adults and adolescents (four months of isoniazid, rifapentine, and moxifloxacin with pyrazinamide for the first two months) and 4HRZ[E] for children with non-severe TB (four months of isoniazid, rifampicin with pyrazinamide, and in certain circumstances with ethambutol, for the first two months).

= Six-month treatment regimens for drug-resistant TB, 6BPaL[M] (six months of bedaquiline, pretomanid, linezolid, with moxifloxacin depending on drug-susceptibility).

x 24 = by the end of 2024!

The 1/4/6×24 Campaign draws inspiration from the legacy of the late Partners in Health (PIH) co-founder Dr. Paul Farmer, who stressed the so-called “five S’s” that countries must have in place to deliver equitable care to the poorest people: stuff, staff, space, systems and support. 1/4/6×24 also nods toward the WHO and UNAIDS 3×5 Initiative, which aspired to put 3 million people living with HIV in low- and middle-income countries on ART by 2005 – a step towards the ultimate goal of universal access to HIV treatment and prevention. Similarly, 1/4/6×24 serves as a collective demand to build the momentum we need to course correct the global fight to end TB.
