2 of 13 (15%) of Evaluable Patients Remain Alive 3.9 and 3.5 Years After Dosing, Respectively
NORTH BRUNSWICK, NJ, USA | July 28, 2010 | Advaxis, Inc., (OTCBB: ADXS - News), the live, attenuated Listeria monocytogenes (Lm) immunotherapy company, has updated the survival information from its phase 1 trial of ADXS11-001 which assessed the safety of this agent in advanced, metastatic, progressive cervix cancer in women whose disease progressed subsequent to treatment with cytotoxic therapy.
The principal investigator for this study has reported that the two (2) patients who were alive in March of 2010 are still alive at 3.9 and 3.5 years post dosing. This observation supports the idea that live attenuated Listeria immunotherapies can result in long lived responses, possibly by stimulating persistent immune memory.
About Advaxis Phase I Trial of ADXS11-001
ADXS11-001 is a live, attenuated Listeria vaccine that targets the human papilloma virus (HPV) oncoprotein E7. HPV is recognized as the cause of cervix cancer. The oncoprotein E7 is one of the HPV proteins believed to be responsible. Doses of 1x109, 3.3x109 or 1x1010 cfu were administered to groups of five (5) women who had failed prior therapy including radiation and chemotherapy. In such cases, no therapy has been found to be effective and the median survival, once disease progression resumes, is typically six (6) months or less; depending upon the treatment given. The one-year historical survival for these patients is approximately five percent (5%).
The phase I trial of ADXS11-001 was intended to assess safety; and, like all phase I trials, was not powered for efficacy. No conclusions can be made based upon the small number of patients treated. However, in this trial, the median survival was 347 days and the one-year survival was fifty-three percent (53%).
