Functional HIV Cure Step Closer To Reality With FDA Approval Of Clinical Human Trials



A possible “functional cure” for HIV has recently been granted FDA approval for further human testing. The method uses genetic modification to cause a specific mutation in the white blood cells of HIV patients which mirrors those found in the naturally immune. It has so far shown to be both receptive and long-lasting.

The novel therapy involves taking stem cells from HIV-infected patients and using a gene editing tool to cause them to form into white blood cells with a specific mutation. The mutation affects a protein known as CCR5, and interferes with the virus’s ability to latch onto blood cells. The mutation occurs naturally in a small percentage of the world’s population and gives these individuals a life-long resistance to HIV infections. Although the virus may remain in their body, without being able to enter the T cells, it cannot replicate and therefore will stay at low numbers, uncompromising the immune system.

In theory, when these genetically edited stem cells are reintroduced into HIV patients they will repopulate the body with cells possessing the same mutation. This would give the patients the same lifetime resistance to the virus’s harm with just one procedure. The method was developed by Sangamo BioSciences Inc., but has also been tested in early human clinical trials by drug research company Calimmune, San Francisco Business Times reported.

According to IFL Science, in a small trial consisting of only 12 patients the procedure was found to be tolerable and have a low risk of adverse side effects. The genetically modified cells lasted up to four years inside the patients. Unfortunately, the trial was not large enough to test the effectiveness of the procedure, but the current FDA approval will allow the testing to be extended to treat more HIV patients. The FDA has also approved the start of a new Phase I safety study, which would consist of a multi-year, three-stage process of human trials to test a similar approach using a different method of disabling the CCR5 protein.
