Tuberculosis Is the Most Common
Infectious Disease
•
•
Worldwide, 2 billion people are infected with TB (LTBI)
16 million+ patients have active TB
• 9.27 million new cases in 2007
• = 139 cases per 100,000 population
• 2 million TB deaths per year
• 1.32 million people not infected with HIV
• 456,000 people who were infected with HIV
• 95% Of TB cases and 98% of TB deaths in low- and middle-income
countries
• 22 high burden countries account for 80% of cases (India,
China, Indonesia, Nigeria, South Africa)
 Globally, tuberculosis is the #1 cause of death in HIV+ patients
•
•
MDR-TB cases = 500,000 in 2007 (289,000 new cases, with highest
rates in India, China, Russia, South Africa, Bangladesh)
55 countries have reported cases of XDR-TB by the end of 2008
Mycobacterium tuberculosis
• Slowly replicating, rod-shaped
Gram-positive bacteria
• Obligate intracellular
pathogen: multiplies in
macrophages
• Inhibition of fusion with
lysosomes
• Waxy cell wall resists
lysosomal enzymes
• Macrophage lifespan is
several months

 MDR-TB
• No global standard of care (4 drugs, one injectable, for 18-24 months)
H = Isoniazid
R = Rifampin
Z = Pyrazinamide
E = Ethambutol
Failure of first-line TB treatment:
drug resistance
• Multidrug-resistant (MDR) TB
In-vitro resistance to at least isoniazid and rifampicin
– 3.6% of all incident TB cases globally are estimated to have MDR-TB
– 390 000–510 000 cases of MDR TB were estimated to emerge in 2008
– The highest proportions of MDR-TB are found in countries of Eastern
Europe and Central Asia
• Extensively drug-resistant (XDR) TB
MDR plus resistance to fluoroquinolones and at least 1 of the 3
second-line injectable drugs (amikacin, kanamycin, capreomycin)
– 963 cases of XDR-TB reported to WHO globally from 33 countries in 2008
– As of Jan 2010, 58 countries had reported to WHO at least one case
of XDR-TB

Diagnosis of MDR-TB
• Risk factors
–
–
–
–
–
History of prior therapy
History of non-adherence
Residence in an MDR-endemic area
Exposure to known or suspected MDR-TB case
HIV infection (in some settings)
• Early recognition of treatment failure
– Lack of sputum conversion, persistent or recurrent cough, continued
fever, night sweats and failure to gain weight
• Drug susceptibility testing (DST)
– WHO recommends DST for previously treated patients and patients
living with HIV (and in all patients at start of therapy where
availability permits)

TMC207: slide 16
Treatment of MDR-TB: general
principles
• Use at least 4 drugs certain to be active
– Drugs to which resistance is known to be rare
– DST results show susceptibility (with good laboratory reliability e.g.
injectables, fluoroquinolones)
– Drugs not commonly used in the area
– Drugs with no prior history of failure in an individual patient
• Do not use drugs for which there is a possibility of crossresistance
• Eliminate drugs that are not safe
• Include first-line agents, injectables and fluoroquinolones before
other options
• If DST unavailable, a standard regimen is proposed by WHO

TMC207: slide 18
Drug interactions
• Relatively few drug interactions substantially change
concentrations of anti-TB drugs
• Anti-TB drugs sometimes change concentrations of other drugs
– Rifamycins can decrease serum concentrations of many drugs,
(e.g., most of the HIV-1 protease inhibitors), to sub-therapeutic
levels
– Isoniazid increases concentrations of some drugs (e.g., phenytoin)
to toxic levels

C208 Stage 2 Objectives
• Demonstrate superiority of TMC207 compared to placebo
at 24 W of treatment
• Primary analysis = time to sputum culture conversion
• Sputum culture conversion is defined as 2 consecutive negative MGIT
cultures collected at least 25 days apart
and not followed by a confirmed positive culture.
• Subjects who drop out during the 24W are considered failed,
irrespective of their culture status at time of dropout.
• Secondary analysis = culture conversion rates at 24 W

Cycloserine/(Terizidone in South Africa).
Changes in the background regimen occurred over time due to:
• DST results and side effects

C208 Safety
• Adverse events evenly distributed across treatment groups
• Discontinuations due to adverse events were unrelated to the study drug
• Placebo: 4 discontinuations during the treatment phase
(drug exposure during pregnancy, amylase/lipase increase, urticaria and pregnancy)
• TMC207: 3 discontinuations during the treatment phase
(transaminase increases: 2 cases of acute Hep B infections and 1 alcoholic binge)
• No serious adverse events related to study drug
• No clinically significant differences in laboratory tests
• QTcF prolongation seen
- no adverse events associated with QTcF changes
- no pathologically prolonged QT intervals (> 500 msec)

Conclusions from study C208
TMC207 was safe and well-tolerated over 24 weeks
Addition of TMC207 to a 5-drug MDR-TB regimen
resulted
• In faster culture conversion within 24 weeks (p=0.003)
• In median time to culture conversion of 12 versus 18 weeks.
• In a higher sputum conversion rate at 24 weeks 79% vs 58%

Tabulation of most frequent AE’s
•Most frequently reported adverse
events (>10%) during the
investigational phase:
•nausea (11%),
•arthralgia (12%) and
•hyperuricaemia (14%)
•22% of the subjects stopped a
background TB drug due to an AE
•2% (n=4)of the subjects stopped
TMC207 prematurely due to an AE
43
Conclusions from study TMC207- C209
•Addition of TMC207 to an individualized MDR-TB regimen:
• Was safe and well-tolerated
• Resulted in an 80% culture conversion rate at week 24,
with median times to culture conversion of:
• 8 weeks for patients with MDR TB
• 12 weeks for patients with Pre-XDR TB
• 24 weeks for patients with XDR TB
•Responder rates were higher for:
• Patients with no cavitations (p* = 0.0157)
• Patients with lower extent of resistance (p* = 0.0006)
• Patients on 3 or more potentially active drugs in their BR
(p* = 0.0376)
