Tentative FDA approval of lopinavir/ritonavir oral pellet formulation closes treatment gap for children with HIV

The Paediatric HIV Treatment Initiative welcomes this important step towards closing the treatment gap for children with HIV

Infants and young children living with HIV will finally have access to an improved formulation of an antiretroviral (ARV) treatment, following the U.S. Food and Drug Administration's (FDA) tentative approval last week of lopinavir/ritonavir (LPV/r) oral pellets developed by the Indian generic company Cipla.

"The announcement of tentative FDA approval of the lopinavir/ritonavir oral pellet formulation is an important step forward in increasing access to World Health Organization-recommended antiretroviral treatment for children under three years of age," said Ambassador Deborah L. Birx, M.D., U.S. Global AIDS Coordinator and U.S. Special Representative for Global Health Diplomacy. "This supports the goals of key PEPFAR initiatives to improve paediatric HIV/AIDS services, including the Accelerating Children's HIV/AIDS Treatment Initiative and the Global Pediatric ARV Commitment to Action".

Until now, the only available version of this combination treatment was a harsh-tasting syrup that required refrigeration and contained 40% alcohol. Only a quarter of children with HIV are currently on treatment and the lack of child-adapted formulations contributes to this unacceptable situation.
"UNITAID and its partners in the Paediatric HIV Treatment Initiative (PHTI)* also welcome the approval of these oral pellets, which brings us a step nearer to closing the shameful treatment gap for the 3.2 million children living with HIV around the world," said Lelio Marmora, Executive Director of UNITAID which is funding the development of paediatric formulations for HIV.

Importantly, intellectual property issues around access to future LPV/r combinations will be reduced, thanks to a licensing agreement the Medicine Patent Pool (MPP) signed in in December 2014 with AbbVie, the patent holder for LPV/r. "This is a crucial licence for paediatric programmes as it benefits low- and middle-income countries where 99% of children with HIV in the developing world live," said Greg Perry, Executive Director of the MPP.

Long-acting drug effectively prevents HIV-like infection in monkeys


Cabotegravir (USAN  and INN ) (also known as S/GSK1265744 or previously referred to by the research code GSK744) is an investigational new drug under development for the treatment of HIV infection. It is an integrase inhibitor, with a carbamoyl pyridone structure similar to dolutegravir. In investigational studies, the agent has been packaged intonanoparticles (GSK744LAP) conferring an exceptionally long half-life of 21–50 days following a single dose. In theory, this would make possible suppression of HIV with dosing as infrequently as once every three months.
HIV researchers hope a new compound, known as cabotegravir, could make dosing easier for some because the drug would be administered by injection once every three months. A clinical trial testing long-acting cabotegravir's safety and acceptability has already begun at multiple U.S. sites including The Rockefeller University Hospital. Meanwhile two new studies, including one conducted by researchers at the Aaron Diamond AIDS Research Center (ADARC) and Rockefeller University, published today (January 15) inScience Translational Medicine, show that long-acting cabotegravir injections are highly protective in a monkey model of vaginal transmission of a virus similar to HIV.
"Clinical trial results have demonstrated that the effectiveness of preventive oral medications can range with results as high as 75 percent effective to as low as ineffective, and a lot of that variability appears to hinge on the patient's ability to take the pills as prescribed," says study researcher Martin
Markowitz, a professor at Rockefeller University and ADARC. "Long acting cabotegravir has the potential to create an option that could improve adherence by making it possible to receive the drug by injection once every three months."

Developed by ViiV Healthcare and GlaxoSmithKline, and previously known as GSK744 LA, cabotegravir is an antiretroviral drug. Antiretrovirals interfere with HIV's ability to replicate itself using a host cell and they are used to treat an HIV infection or to prevent those at high risk from acquiring it in the first place.

Geranium extracts inhibit HIV-1

Extracts of the geranium plant Pelargonium sidoides inactivate human immunodeficiency virus type 1 (HIV-1) and prevent the virus from invading human cells. Scientists report that these extracts represent a potential new class of anti-HIV-1 agents for the treatment of AIDS.

Nail Fungus Drug Might Help Against HIV, Study Suggests - MedNews

We know that, Ciclopirox olamine (used in preparations called BatrafenLoproxMycosterPenlac and Stieprox) is a synthetic antifungal agent for topical dermatologic treatment of superficial mycoses. It is most useful against Tinea versicolor.

According to a new study this  drug used to treat nail fungus may hold promise against HIV, the virus that causes AIDS.

FDA Approves Intelence (Etravirine) for Pediatric Patients...

U.S. Food and Drug Administration (FDA) has approved Intelence (etravirine) to be administered in combination with other antiretroviral (ARV) medications for treatment of human immunodeficiency virus 1 (HIV-1) in treatment-experienced pediatric patients (6 years to <18 years old) who are experiencing virologic failure with HIV-1 strains resistant to a non-nucleoside reverse transcriptase inhibitor (NNRTI) and other ARVs.

This approval, which follows FDA priority review of the company’s supplemental New Drug Application, expands the Intelence indication and makes it the only NNRTI indicated for this use in both treatment-experienced children and adults with resistance to an NNRTI and other ARVs. The approval includes a new 25mg dose to allow for weight-based dosing in pediatric patients (6 years to <18 years old and weighing at least 16kg or 35.2 lbs). The 25mg tablet is expected to be available in the first half of May.
