Bacteria can become resistant to any antibiotic due to inappropriate treatment, such as when it is interrupted or the medicine is used inappropriately.2 When the TB bacteria becomes resistant to at least isoniazid and rifampicin, it is called MDR-TB.1
Otsuka has had a TB medicine discovery programme for over 50 years and has been a recognised leader in TB research through its commitment to the development of new TB compounds as well as the building of a clinical infrastructure within developing countries affected by the disease.
One of the compounds developed by Otsuka has received regulatory approval for the treatment of adults with pulmonary MDR-TB and was one of the first TB medicines in about 50 years.3 Apart from continuing its research and development programme, Otsuka is also engaging in multiple third-party collaborations looking at shorter, more effective and more patient-friendly ways to fight MDR-TB.
One such collaboration will explore the safety and efficacy of Otsuka’s second anti-TB compound as part of an all-oral, Pan-TB regimen.
