August 25, 2006—Protease inhibitor lopinavir, one of two HIV meds in Kaletra, may also treat the human papilloma virus (HPV), which can lead to cervical and anal cancer, according to preliminary tests by British scientists. The FDA approved an HPV vaccine earlier this year, but that won’t be any help to those already infected with HPV. Investigators hope a lopinavir-based cream might one day provide an alternative to surgery for getting rid of precancerous HPV lesions.
