BIOVEX AGREES SPA WITH THE FDA FOR A PIVOTAL STUDY
WITH ONCOVEXGM-CSF IN METASTATIC MELANOMA AND ANNOUNCES PRESENTATION
OF PHASE II RESULTS AT ASCO
FDA agrees to first SPA for an oncolytic product
Woburn, MA, April 22nd, 2008 BioVex
Inc, a biotechnology company developing clinical stage treatments
for cancer and the prevention of infectious disease, announced today
that the U.S. Food and Drug Administration (FDA) has approved the
design of a single, pivotal, Phase III clinical trial evaluating
its lead product, OncoVEXGM-CSF in previously treated patients with
metastatic melanoma. The agreement was made under the special Protocol
Assessment (SPA) procedure.
BioVex is currently concluding a 50-patient Phase II trial for OncoVEXGM-CSF as stand alone therapy in patients with unresectable Stage IIIc and
Stage IV metastatic melanoma. The trial was designed to measure overall
objective response, which is defined as a complete response (CR),
where disease is completely eliminated, or partial response (PR),
where there is a >30% reduction in disease burden. Interim
results from the study demonstrated a highly encouraging rate of
durable objective response with multiple patients with metastatic
disease at enrollment having been declared disease free following
therapy. The full study has been accepted for oral presentation at
ASCO on June 1st where the results will be presented.
The Phase III study design agreed with the FDA follows directly
from the study design successfully employed in Phase II. The Phase
III study will also enroll previously treated patients with unresectable
stage IIIc and stage IV disease using OncoVEXGM-CSF as monotherapy.
The primary efficacy endpoint will also be response rate-based; the
primary objective being to demonstrate a statistically significant
increase in the rate of objective responses maintained for six months
or more, in comparison to control therapy (subcutaneously administered
GM-CSF). The study is intended to enroll 360 evaluable patients randomized
such that 240 patients receive OncoVEXGM-CSF and 120 patients receive
control.
The pivotal study is expected to commence in the first quarter of
2009, with a potential projected BLA filing in late 2010. BioVex
is currently commissioning its GMP manufacturing facility in Woburn,
Massachusetts, which is intended to provide product for Phase III
studies and launch.
Dr Robert Coffin, Chief Technology Officer for BioVex, said:
“This agreement with the FDA for the pivotal Phase III
study design for OncoVEXGM-CSF in
melanoma, which uses a very similar design as successfully employed
in Phase II, is a significant event for BioVex. We believe the Phase
II study results relating to durable objective response provide a
sound basis on which to proceed with confidence to Phase III where
the primary objective is to demonstrate a statistically significant
increase in durable objective responses as compared to control therapy.
We look forward to the presentation of the Phase II results at ASCO,
and thereafter to the initiation of the pivotal study.”
About BioVex
BioVex is a privately held biotechnology Company based in Woburn.
MA. The Company is developing a new class of potent biologics
for the treatment of cancer and prevention of infectious
disease.
The Company’s lead cancer technology platform, OncoVEXGM-CSF,
is an unpartnered, first-in-class oncolytic, or cancer destroying
virus technology. OncoVEXGM-CSF works
by: 1) replicating and spreading within solid tumors, causing the
death of cancer cells; while 2) stimulating the immune system to
destroy metastatic deposits. Both modes of action have been clearly
validated in the clinic, where multiple patients with metastatic
disease progressing at enrollment have been declared disease free.
Based on the strength of the clinical data generated to date, coupled
with a benign side effect profile, BioVex believes OncoVEXGM-CSF has the potential to become a leading standard of care in the treatment
of many solid tumors.
OncoVEXGM-CSF is currently completing a Phase II clinical trial for melanoma and
Phase I/II clinical trials for head & neck cancer and pancreatic
cancer.
The Company's second program is a vaccine for genital herpes,
ImmunoVEXHSV2, which provides complete
protection in animal models of the disease. A Phase I study with
ImmunoVEXHSV2 is scheduled to initiate later this year.
