ZIOPHARM
Oncology Announces First Patient Dosed in Phase I Study of
Palifosfamide
in Small Cell Lung and Other Cancers
NEW YORK, NY (December 29, 2010) –
ZIOPHARM Oncology, Inc. (Nasdaq: ZIOP), announced today that the first
patient has been dosed in a Phase I, single arm, dose escalation study at the
Indiana University Cancer Center of intravenous (IV) palifosfamide (ZIO-201) in
combination with etoposide (VP-16) and cisplatin/carboplatin (platinum) in the
treatment of small cell lung cancer (SCLC) and other cancers.
The Phase
I study is expected to enroll 12 to 15 patients and will assess the safety of
the palifosfamide/etoposide/platinum regimen for the planned randomized Phase II
study in SCLC patients with extensive disease where the etoposide/platinum
combination is standard of care.
Palifosfamide
is a novel, bi-functional DNA alkylator and cross-linker, currently in a Phase
III trial for soft tissue sarcoma, and comprises the functional active
metabolite of ifosfamide (IFOS). IFOS is a pro-drug and must be metabolized in
order to be active. The clinical utility of IFOS is often limited by toxicities
associated with IFOS metabolites unrelated to DNA-alkylation and
by development of resistance conferred by decreased pro-drug activation. IFOS
was formally studied in SCLC by the Indiana group where it was added to
etoposide and platinum with evidence of significantly enhanced efficacy as
measured by the endpoints of progression free survival and survival but with the
added toxicity of IFOS negating benefit (Journal of Clinical Oncology, Vol 13,
2594-2599).
“The
efficacy data and low toxicities observed with palifosfamide in clinical and
preclinical studies together with the known activity of ifosfamide in SCLC
provide strong rationale for studying palifosfamide in combination with the
standard of care for this extraordinarily difficult to treat cancer,” said
Lawrence Einhorn, MD, Distinguished Professor at the Simon Cancer Center of
Indiana University Medical Center, Lance Armstrong Foundation Chair in Oncology,
former President of ASCO and a member of ZIOPHARM's Medical Advisory
Board. “Small cell lung cancer in particular is a disease in urgent need
of more effective and better tolerated treatment options.”
According
to the American Cancer society approximately 15 percent of lung cancers are
SCLC, or approximately 33,400 patients yearly in the U.S. SCLC is
almost exclusively associated with cigarette smoking and the majority of
patients with extensive disease are treated front-line but relapse with a very
high mortality within one year.

About
ZIOPHARM Oncology, Inc.:
ZIOPHARM
Oncology is a biopharmaceutical company engaged in the development and
commercialization of a diverse portfolio of cancer drugs. The Company
is currently focused on three clinical programs.
Palifosfamide
(ZymafosTM or
ZIO-201) is a novel DNA cross-linker in class with bendamustine, ifosfamide, and
cyclophosphamide. ZIOPHARM is currently enrolling patients in a randomized,
double-blinded, placebo-controlled Phase III trial with palifosfamide
administered intravenously for the treatment of metastatic soft tissue sarcoma
in the front-line setting. The Company is also currently conducting a
Phase I intravenous study of palifosfamide in combination with standard of care
addressing small cell lung cancer and expects to initiate an additional study
with drug in the oral form treating solid tumors.
Darinaparsin
(ZinaparTM or
ZIO-101) is a novel mitochondrial-targeted agent (organic arsenic) being
developed intravenously for the treatment of peripheral T-cell lymphoma with a
pivotal study expected to begin in late 2011. An oral form is in a Phase I trial
in solid tumors.
Indibulin
(ZybulinTM or
ZIO-301) is a novel, oral tubulin binding agent that is expected to have several
potential benefits including oral dosing, application in multi-drug resistant
tumors, no neuropathy and minimal overall toxicity. It is currently being
studied in Phase I/II in metastatic breast cancer.
ZIOPHARM's
operations are located in Boston, MA with an executive office in New York City.
