Merck known as MSD outside the United States and Canada, has received the US Food and Drug Administration (FDA) approval for ISENTRESS, a new paediatric formulation and oral suspension of Merck’s integrase inhibitor. With this approval, ISENTRESS is now indicated in combination with other antiretroviral (ARV) agents for the treatment of HIV-1 infection in patients four weeks of age and older.

The use of other active agents with ISENTRESS is associated with a greater likelihood of treatment response. The oral suspension may be used in patients as young as four weeks of age, weighing at least three kg to less than 20 kg. The safety and efficacy of ISENTRESS have not been established in infants less than four weeks of age. Formulations of ISENTRESS for specific populations now include oral suspension, chewable tablets and film-coated tablets.

“We are very pleased that ISENTRESS can now be a part of a treatment regimen for HIV-1 infected infants and children as young as four weeks of age,” said Hedy Teppler, executive director, Clinical Research, Merck Research Laboratories.

Merck anticipates that the oral suspension formulation will be available in the United States during the third quarter of 2014.
