New Drugs for TB

  • New diagnostics, drugs and vaccines are necessary to achieve the ambitious targets set in the End TB Strategy (WHO TB Report 2016)

Tuberculosis (TB) is a bacterial infection that causes more deaths in the world than any other infectious disease, second only to AIDS. (See the report on Tuberculosis from the It is caused by the pathogen Mycobacterium tuberculosis, which is mostly carried (mostly in a latent form) in about two billion people worldwide. Before the discovery of the causative bacteria, TB was also called "consumption" or "chronic wasting disease". It also claimed the lives of famous people such as Johannes Calvin, Frédéric Chopin, Franz Kafka, Molière, Napoleon II and Voltaire.

The TB epidemic is larger than previously estimated, reflecting new surveillance and survey data from India. According to the Global Tuberculosis Report 2016 from the WHO, TB remains one of the top 10 causes of death worldwide. In 2015, an estimated 10.4 million new TB cases were reported worldwide, and 1.4 million people have died in 2015 from TB, with an additional 0.4 million deaths resulting from TB disease among people living with HIV. TB mostly kills people in low-income countries that have limited access to modern medicine. In addition, poor compliance with existing treatments has led to the development of multidrug resistant (MDR) TB strains, which have been exacerbated due to a lack of new treatments in the last 40 years. In 2015 there were an estimated 480 000 new cases of MDR-TB.

Like the common cold, TB is contagious and airborne, spread by infected people that cough or sneeze. It usually affects the lungs, but may also affect the brain, kidneys and other parts of the body. While the TB death rate has decreased 22% between 2000 and 2015 with 49 million lives saved through effective diagnosis and treatment, 6.1 million newly diagnosed cases were notified to national TB authorities and reported to WHO.

TB Hard Facts 2015 (from the WHO report 2016)

  • 10.4 million new incident TB cases worldwide
  • 5.9 million (56%) of those new TB cases were among men,
  • 3.5 million (34%) among women and
  • 1.0 million (10%) among children.
  • People living with HIV accounted for 1.2 million (11% of all new TB cases)
  • 1.8 million people died from TB

Resistance in tuberculosis 2015 (WHO Report 2016)

  • An estimated 480 000 people developed multi-drug resistant TB (MDR-TB)
  • In addition, an estimated 100 000 people developed resistance to rifampicin (RR-TB)
  • Global data show an average cure rate of only 52% for treated MDR-TB patients
  • Extensively drug-resistant TB (XDR-TB) is reported worldwide with 9.5% of people with MDR-TB to have XDR-TB.

The following picture shows those countries with the percentages of new TB cases with MDR/RR-TB

Treatment of TB is much more time-consuming than for other infections. The standard treatment usually takes six months if the patient is infected with drug susceptible TB strains which are not resistant. However, infections with MDR- and XDR-TB require therapies of >18months with drug cocktails that are less potent, but more toxic and expensive than standard medications.
