A commonly-used HIV drug has been shown to kill-off the human papilloma virus (HPV) that leads to cervical cancer in a world-first clinical trial led by The University of Manchester with Kenyatta National Hospital (KNH) in Nairobi.
Drs Ian and Lynne Hampson, from the University’s Institute of Cancer Sciences and Dr Innocent Orora Maranga, Consultant in Obstetrics and Gynaecology at KNH in Nairobi examined Kenyan women diagnosed with HPV positive early stage cervical cancer who were treated with the antiviral HIV drug lopinavir in Kenya.
The study looked at 40 women with both high and low-grade pre-cancerous disease of the cervix and the antiviral drug, normally used orally to treat HIV, was self-applied directly to the cervix as a pessary.
The results, due to be presented at two international scientific conferences later this month and next, showed a high proportion of women diagnosed with HPV positive high-grade disease returned to normal following a short course of the new treatment.The findings build on previous peer-reviewed laboratory based research carried out by Drs Hampson and will be submitted to a journal soon.
They have been described by an independent leading specialist in gynaecological cancer as very impressive. The 40 women, who were all HPV positive with either high-grade, borderline or low grade disease, were treated with one capsule of the antiviral drug twice a day for 2 weeks.
Repeat cervical smears showed a marked improvement within one month of the treatment although after three months, there was a definite response. Out of 23 women initially diagnosed with high-grade disease, 19 (82.6%) had returned to normal and two now had low-grade disease giving an overall positive response in 91.2%.of those treated.
