ZIOPHARM
Presents Safety and Preliminary Efficacy Data from Two
Phase
I Studies of Indibulin at AACR Centennial Conference
Studies
Demonstrate Indibulin is Well Tolerated and
Shows
Early Activity in Several Tumor Types
Monterey,
CA, July 23, 2008 -
ZIOPHARM Oncology, Inc. (NASDAQ:ZIOP) announced today that it presented data
from two Phase I studies of indibulin, the Company’s novel, orally administered,
synthetic tubulin targeted agent, at the American Association for Cancer
Research (AACR) Centennial Conference on Translational Cancer Medicine 2008:
Cancer Clinical Trials and Personalized Medicine held in Monterey, California,
July 20 to 23, 2008.
A
total
of 34 patients have been treated in the two Phase I studies (Phase I and Phase
Ib), and safety, tolerability and early activity are being evaluated from
varying doses and dose schedules. Study patients presented with sarcomas and
a
variety of carcinomas, including pancreatic, thyroid, ovarian, prostate and
lung
cancers. To date, 24 patients have received at least two cycles of therapy
and
are evaluable for efficacy using RECIST criteria. Of these, prolonged stable
disease of greater than 4 months has been observed in 11 patients, with 3 of
these patients reaching eight or more months to date. In addition, early PET
scans have demonstrated 1 complete reduction in uptake, 6 with partial reduction
in uptake, and 4 with increased uptake. Tumor responses measured by PET scan
are
generally referred to as metabolic responses, and usually correlate with
treatment responses in cancer. The most common study drug-related toxicities
reported were mild to moderate fatigue, nausea, diarrhea and anorexia. Unlike
studies of other microtubule targeting agents, no neurotoxicity and minimal
bone
marrow suppression were observed.
“Early
data suggests that indibulin is clearly active in a number of cancers, and
maintains a toxicity profile that distinguishes it from other tubulin binding
agents such as the taxanes and vinca alkaloids,” said Sant P. Chawla, M.D.,
Director, Sarcoma Oncology Center, Santa Monica, and a lead investigator of
the
study. “Notably, the common and serious side effects typically associated with
this class of therapy have not been observed. We look forward to seeing
indibulin developed in tumor specific studies.”

more
details on these trials please see www.clinicaltrials.gov.
About
Indibulin
Indibulin
is a novel synthetic anti-mitotic agent that binds to tubulin, destabilizes
microtubule polymerization, arrests tumor cell growth at the G2/M phase and
inhibits cell mobility and metastasis. Microtubules are well-established targets
for anti-cancer drug development and tubulin-binding drugs such as taxanes
and
vinca alkaloids are currently widely used to treat cancer. Indibulin is orally
available, lacks neurotoxicity and has efficacy in taxane refractory preclinical
models.
