Abbott's Kaletra(R) and Aluvia(R) (lopinavir/ritonavir) New Lower-Strength Tablet for Pediatric Use Receives Positive Opinion from EMEA


Abbott Park, Illinois (ots/PRNewswire) -

- Lopinavir/ritonavir tablet is the first and only co-formulatedprotease inhibitor tablet approved for use in children with HIV

Abbott (NYSE: ABT) announced today that the European Committee forMedicinal Products for Human Use (CHMP), the scientific committee ofthe European Medicines Agency (EMEA), has issued a positive opinionrecommending approval of a new, lower-strength tablet formulation ofthe company's leading HIV protease inhibitor, Kaletra(R)(lopinavir/ritonavir). In addition, the CHMP has adopted a positiveopinion, in coordination with the World Health Organization (WHO),for Aluvia(R) (lopinavir/ritonavir), the tradename of the samelower-strength tablet formulation in developing countries.

The new lower-strength formulation is suitable for pediatric useand represents a significant breakthrough for clinicians and patientsin developing countries, where more than 2 million of the estimated2.3 million children worldwide with HIV/AIDS live. The first and onlyco-formulated protease inhibitor tablet that can be used in children,the tablets do not require refrigeration and can be taken with orwithout a meal -- an important advance in delivering HIV medicine indeveloping countries.

"EMEA approval is an essential first step to registering thetablet in Europe and most developing countries and it is welcome newsfor physicians and caregivers of children with HIV," said Mark Kline,M.D., professor of pediatrics, chief of Retrovirology, director, AIDSInternational Training and Research Program, and director, Baylor-CDCGlobal AIDS Technical Assistance Project, Baylor College of Medicine."The development of this product, which does not requirerefrigeration, is not only a scientific development tailored to theneeds of patients, especially children, but also is a huge advance inthe care of patients in resource-limited settings." Kline is alsopresident of the Baylor International Pediatric AIDS Initiative atTexas Children's Hospital, which has opened six pediatric centers ofexcellence throughout Africa and in Romania. Together, these clinicsare providing HIV care and treatment to more than 20,000 children.

Next Steps for Making Lower-Strength Pediatric Tablets BroadlyAvailable

The European Commission will review the CHMP's positive opinionfor Kaletra and is expected to issue a final decision for marketingauthorization for the lower-strength Kaletra in the European Unionwithin the next 60-90 days.

The regulatory review processes in many developing countriesrequire products to receive positive opinion from the Committee forMedicinal Products for Human Use (CHMP), the scientific committee ofthe EMEA. The positive opinion is necessary for obtaining aCertificate of Pharmaceutical Product (CPP) -- often a prerequisitefor regulatory filing in developing countries.

In order to expedite review in developing countries, Abbott isworking with regulatory agencies on a country-by-country basis tonegotiate submissions before the CPP is available.

The price of the recently approved lower-strength tablet will behalf the price of the original-strength tablet everywhere it isavailable.

Based on the U.S. Food and Drug Administration (FDA) approval onNovember 9, 2007, Abbott is shipping the lower-strength tablets tocountries that have issued approved waiver orders. On December 1,2007, Uganda, the first country to issue such a waiver order, was oneof the first countries in the world -- and the first country inAfrica -- to receive the lower-strength tablets. The UgandanGovernment's early approval of the waiver allowed Dr. Victor Musiimeof the Joint Clinical Research Centre in Kampala to write the firstprescription for the lower-strength tablet just days after theproduct received marketing authorization in the United States. OtherAfrican governments are now also talking to Abbott about thepossibility of waiver shipments. According to UNAIDS, an estimated110,000 Ugandan children were living with HIV in 2005.

The WHO recommends lopinavir/ritonavir as the preferred treatmentfor children who no longer respond to first-line HIV medicine. TheU.S. Department of Health and Human Service recommendslopinavir/ritonavir for the initial treatment of children with HIV.

Kaletra Lower-Strength Tablets

The new tablet formulation will complement Kaletra oral solution,which has been available for pediatric use since its approval inSeptember 2000 in the United States. For pediatric patients,lower-strength Kaletra tablets will offer more dosing flexibility andcontains 100mg of lopinavir and 25mg of ritonavir, compared with theoriginal tablet strength of 200mg of lopinavir and 50mg of ritonavir,most commonly used by adults.

"Abbott has kept the needs of children living in the developingworld firmly in mind when making decisions about the development,manufacturing and delivery of our innovative product," said ScottBrun, M.D., divisional vice president, infectious diseases, GlobalPharmaceutical Research and Development, Abbott. "We have beenaddressing the growing epidemic of HIV in children for more than adecade and will continue to for years to come."

Background on HIV in Children

According to the Joint United Nations Programme on HIV/AIDS(UNAIDS), in 2006, an estimated 2.3 million children under the age of15 were living with HIV/AIDS worldwide; a vast majority -- 2 millionchildren with HIV/AIDS -- was living in Africa. Last year alone, anestimated 530,000 children were infected with HIV, and 380,000children died of AIDS.

Based on 2004 Centers for Disease Control and Prevention (CDC)data for 33 states, an estimated 3,336 children under the age of 13were living with HIV/AIDS in the United States. While the number ofpediatric AIDS cases has decreased overall in the U.S., the riskamong African-American and Hispanic infants and children is ofspecial concern. Among U.S. children living with AIDS, 63 percent areAfrican-American, 21.6 percent are Hispanic, and 14.2 percent areCaucasian.
