ADXS-Advaxis Provides Phase 1 Data of Higher Dose Axalimogene Filolisbac
PRINCETON, N.J., March 27, 2017 (GLOBE NEWSWIRE) -- Advaxis, Inc. (NASDAQ:ADXS), a biotechnology company developing cancer immunotherapies, today published online a poster previously presented at the National Cancer Research Institute (NCRI) Cancer Conference in Liverpool that showed axalimogene filolisbac achieved durable response in a patient with persistent or recurrent metastatic (squamous or non-squamous cell) carcinoma of the cervix (PRmCC).
Nine patients who had documented disease progression after they had received curative treatments of chemotherapy and/or radiation with or without bevacizumab were enrolled in this phase 1, open-label, dose-determining study. Axalimogene filolisbac was well-tolerated across two dose levels. The study also established a recommended phase 2 dose of 1×10(10) CFU and demonstrated antitumor activity at that dose. Axalimogene filolisbac was safely administered at 5 and 10 times the dose levels previously studied, without any significant toxicity. One patient experienced an ongoing and durable partial response. This patient was recently featured in the Augusta Chronicle, as she is being treated at the Georgia Cancer Center at Augusta University. Read the full Augusta Chronicle article here.
"The best overall tumor response in eight of the nine enrolled patients is encouraging in evaluating the potential of axalimogene filolisbac," said Sharad Ghamande, principal investigator and Professor and Director of Gynecologic Oncology at the Georgia Cancer Center at Augusta University. "We were pleased to see a sustained and durable partial response in one patient, which is very rare for this kind of tumor that is unresponsive to chemotherapy, and survival in these patients is often less than 10 months. In addition, we could safely administer the drug at 5 and 10 times the dose levels previously studied, without any significant toxicity."
There was only one instance of dose-limiting toxicity, with that patient experiencing a grade 3 treatment related adverse event (TRAE) of hypotension at a dose of 5×10(9) CFU. Across all doses, eight of nine patients experienced a grade 1-2 TRAE, including chills, nausea and hypotension.
The poster on the phase 1 data, "High-dose treatment with ADXS11-001, a Listeria monocytogenes-listeriolysin O (Lm-LLO) immunotherapy, in women with cervical cancer: a phase I, dose-escalation study" (no. 58) is available at www.advaxis.com. The company is preparing to initiate a phase 3 trial in PRmCC later this year.
