AVAX Technologies Launches Global Phase III Registration Clinical Trial of M-Vax in Metastatic MelanomaStudy protocol the subject of a Special Protocol Assessment with the US FDA
PHILADELPHIA & LYON, France--(HSMN NewsFeed)--AVAX Technologies, Inc. (OTCMarket:AVXT.OB) today announced it has been notified by the U.S. Food and Drug Administration (FDA) that AVAX has been cleared to launch its Phase III Registration Study for M-Vax, its AC Vaccine Therapeutic for the treatment of Metastatic Melanoma. As previously announced by AVAX, the FDA has provided the Company a Special Protocol Assessment related to the planned protocol. The SPA is a written agreement between AVAX and the FDA regarding the trial design, surrogate endpoints to be used as a basis of filing for accelerated approval of M-Vax and the statistical analysis plan necessary to support the full regulatory approval of M-Vax.
"We are happy to have been able to work successfully with the FDA to allow us to start this very important clinical study," noted Dr. David Berd Chief Medical Officer of AVAX. "We have designed a clinically relevant Phase III program that allows us to evaluate the safety and effectiveness of M-Vax in a setting where we believe our treatment has the best opportunity to demonstrate clinical superiority. Our initial Phase II data in combination with more recent publications and patient reports in our compassionate use program provides us with a high degree of confidence that M-Vax may be a promising treatment option for patients suffering from metastatic melanoma."
The Phase III study will enroll up to 387 patients with stage IV melanoma, who will be assigned in a double-blind fashion at a 2:1 ratio to M-Vax or Placebo vaccine. The M-Vax arm will consist of an initial dose of M-Vax (autologous DNP-modified tumor cells) followed by cyclophosphamide (CY) and then six weekly doses of M-Vax administered with Bacillus of Calmette and Guerin (BCG). Following vaccine administration patients will receive a course of low dose IL-2 administered subcutaneously. Patients assigned to the control group will receive a treatment identical to the M-Vax group, except that a Placebo Vaccine will replace M-Vax. The primary endpoints of the study are best overall anti-tumor response rate and the percentage of patients surviving 2 years. Secondary endpoints of the study will include overall survival time, response duration, percentage complete and partial responses, progression free survival and treatment related adverse events.
The data analysis plan for the study includes an interim analysis of Best Overall Response Rate (complete and partial) to be performed when half the patients (194 patients) have completed assessment of their best anti-tumor response, with a second assessment of response evaluated after full enrollment. The comparison of the best overall response rates for the M-Vax and control groups will be used as the basis for an expected initial Biologics License Application (BLA) submission under 21 CFR 601 Subpart E, which provides for accelerated approval using a surrogate endpoint in certain life threatening diseases. The analysis of overall survival will be performed when surviving patients have reached the two-year point.
"We have completed two very significant milestones at AVAX, obtaining the SPA agreement with the FDA and obtaining authorization to launch this important Phase III Registration Study," said Richard P. Rainey, President of AVAX. "With the SPA agreement in place and the planned interim analysis, we look forward to accelerating the execution of the clinical study and seeing the outcome of this very important Phase III trial."
The planned study will be conducted at Centers in the U.S., Europe and Australia. Based upon initial assessments of study initiation, expected enrollment times and occurrence of events it is currently estimated that the interim study data analysis of response rate could occur in 2008, with the final response rate evaluation expected in 2010 and overall survival data generated in the 2012-2013 timeframe. The Company will update and monitor the study progress quarterly and annually in its reports filed with the Securities and Exchange Commission.
About M-Vax (the AC Vaccine Product Candidate for the Treatment of Melanoma)
The AC Vaccine is a therapeutic treatment prepared by attaching a small chemical to the patient's tumor cells in a process known as haptenization. This hapten modification allows the tumor cells to stimulate a T cell-based immune response to a patients own tumor cells. An early indicator of T cell immune activity is Delayed Type Hypersensitivity (DTH). A previously published article in the Journal of Clinical Oncology, February 2004 reported actual five-year survival data for a group of 214 patients with clinically evident Stage III melanoma treated with the AC Vaccine following surgery. The study demonstrated five-year survival of 45% and showed a highly statistically significant relationship between survival and DTH to patients' own tumor cells. Notably, based upon these results, DTH appears to be a viable "surrogate marker" for survival and an early indicator for clinical effectiveness of current and future product candidates. Previously clinical trials in ovarian and renal cell carcinoma, demonstrated strong DTH responses consistent with those reported for melanoma patients.
About Malignant Melanoma
The American Cancer Society reports that cancer of the skin is the most common of all cancers. Melanoma currently accounts for about 4% of skin cancer cases but is responsible for 80% of skin cancer deaths annually. It is estimated that there will be 55,100 new cases of melanoma annually in the U.S. with approximately 14% diagnosed as late stage metastatic melanoma. Worldwide it is expected that approximately 132,000 people will be diagnosed with melanoma each year and approximately 37,000 people are expected to die of the disease each annually.
