Geneva – The World Health Organization (WHO) recently released new rapid guidance recommending that children of all ages with drug-resistant tuberculosis (DR-TB) have access to all-oral treatment using the drugs bedaquiline and/or delamanid.
However, adopting these new recommendations in high TB burden countries requires access to the paediatric formulations of bedaquiline (produced by Johnson & Johnson) and delamanid (produced by Otsuka and its local partner Viatris).
Doctors Without Borders/Médecins Sans Frontières (MSF), therefore, calls on governments of high-burden countries to take measures to overcome patent barriers and allow the production of these lifesaving drugs through generic manufacturers.
“The WHO’s updated rapid guidance is an important step forward for younger children with drug-resistant TB to receive all-oral treatment without painful injectable drugs,” says Dr Mabel Morales, MSF medical coordinator in India.
“However, this new guidance will remain a distant reality for children unless access barriers to paediatric formulations of bedaquiline and delamanid are overcome, allowing them to be rolled out by national TB programmes in all high-burden countries,” says Morales.
In addition to the slow pace of national guideline changes, access to children’s formulations has been a challenge in high TB burden countries due to high prices and the lack of registration and generic competition.
In our teams’ experience, the registration and supply of paediatric formulations are not prioritised by pharmaceutical corporations and having only one manufacturer for a given drug often results in these formulations being more expensive than the adult versions.
“The high price of delamanid of $1,700 per treatment course has significantly limited access in many countries,” says Morales. “In India, negotiations with Otsuka and Viatris have been unsuccessful, with the manufacturers refusing to lower the price to the $942 – currently being offered to South Africa by Viatris.
“The price of paediatric formulations of bedaquiline also remain too high. It’s time to smash the status quo: pharmaceutical corporations Johnson & Johnson and Otsuka must open up to generic supply and lower prices in order for TB programmes to scale up all-oral treatment regimens,” Morales says.
“As treatment providers, we see kids with drug-resistant TB on an almost daily basis in our independent clinic in Mumbai,” says Morales. “We no longer want to see these younger children suffer the terrible side effects of the older and painful injection-based drugs, when safer and more effective oral medicines are available elsewhere.”
