�New  stage IIb  data from Tibotec  
Pharmaceuticals  Ltd.  provides additional information on the safety and 
efficaciousness of TMC278,  the company's once-daily, investigational             
non-nucleoside reverse transcriptase inhibitor (NNRTI),  as part of HIV  
combination therapy in treatment-naive adults. These  findings were                 
presented today at the International  AIDS  Conference  (AIDS  2008) in Mexico  
City.
     
Seventy-six  percent of patients receiving the 25 mg dosage of TMC278,       
which is being studied in phase III  trials, achieved an undetectable viral 
load (
    
"NNRTIs  have been an integral section of combination antiretroviral               
therapy for over a decennium," said clinical trial investigator Peter  Shalit,  
M.D.  Swedish  Medical  Center,  Seattle,  WA.  "The  phase IIb  information show            
potential difference for TMC278  as a once-daily discussion option for patients wHO have 
non previously taken anti-HIV  medications."
    
TMC278  is an investigational product, and the safety and efficaciousness of 
it, in combination with other antiretroviral agents, has non been                   
established. Two  major phase III  trials for TMC278  ar being conducted in 
Africa,  Asia,  Europe,  North  America  and South  America,  and are currently 
recruiting treatment-naive adult patients.
Study  Design
     
The  phase IIb  dose-finding study (TMC278-C204)  evaluated the efficaciousness,         
tolerability and safety of once-daily TMC278  at threesome blinded doses (25 mg, 
75 mg, and cl mg) and included an open label EFV  600 mg sleeve. A  add up of 
368 patients were randomised to receive one of the three doses of TMC278  or 
EFV,  and all patients standard a background regimen of two nucleoside 
reverse transcriptase inhibitors (NRTIs),  zidovudine + lamivudine (AZT/3TC)  
or tenofovir + emtricitabine (TDF/FTC).
Safety  Results
     
Of  patients in the TMC278  combined group compared with EFV,  9 per centum 
vs. 21 percent experienced rash, 31 percent vs. 48 percentage experienced 
flighty system untoward events and 16 per centum vs. 21 percent experienced 
psychiatric events.
    
Overall,  patients in the TMC278  combined group (all doses) vs. the EFV        
group experienced similar incidences and types of dangerous adverse events 
(SAEs)  (12 percent vs. 15 pct), grade 3 or 4 adverse events (AEs),  (27 
percent vs. 21 percentage) and grade 3 or 4 lab abnormalities (26 
percent vs. 24 pct).
    
TMC278  is the third anti-HIV  compound to be developed by Tibotec                  
Pharmaceuticals,  which is also developing investigational compounds for the 
treatment of hepatitis C  and tuberculosis.
