ZIO-101
(darinaparsin) is an organic arsenic compound covered by issued U.S.
patents and applications internationally. A form of commercially
available
inorganic arsenic (arsenic trioxide (Trisenox ®)
or ATO) has been approved for the treatment of acute promyelocytic
leukemia (APL), a precancerous condition, and is on the compendia
listing
for the therapy of multiple myeloma as well as having been studied
for the
treatment of various other cancers. Nevertheless, ATO has been shown
to be
toxic to the heart, liver, and brain, limiting its use as an anti-cancer
agent. Inorganic arsenic has also been shown to cause cancer of the
skin
and lung in humans. The toxicity of arsenic generally is correlated
to its
accumulation in organs and tissues. Our preclinical and clinical
studies
to date have demonstrated that ZIO-101 is considerably less toxic
than
inorganic arsenic, particularly with regard to heart toxicity. Similar
results have been reported for other organic species. In
vitro
testing of ZIO-101 using the National Cancer Institute’s human cancer cell
panel detected activity against lung, colon, brain, melanoma, ovarian
and
kidney cancer. Moderate activity was detected against breast and
prostate
cancer. In addition to solid tumors, in
vitro
testing in both the National Cancer Institute’s cancer cell panel and
in
vivo
testing in a leukemia animal model demonstrated substantial activity
against hematological cancers (cancers of the blood and blood-forming
tissues) such as leukemia, lymphoma, myelodysplastic syndromes and
multiple myeloma. Preclinical studies have also established antiangiogenic
properties of ZIO-101 and also support the development of an oral
form of
the drug.
|
|
|
Phase
I testing of the intravenous (IV) form of ZIO-101 in both solid tumors
and
hematological cancers is completed. The Company has reported encouraging
signs of clinical activity along with an expected safety profile
in both
of these studies. The Company is presently conducting phase II studies
in
advanced myeloma, certain other hematological cancers, and primary
liver
cancer and has reported on early patient treatment in both of the
blood
cancer trials. ZIOPHARM currently expects to complete enrollment
in both
of these hematological studies by year-end and the liver trial in
the
first quarter of 2008. The Company has recently opened a phase I
study for
an oral form of ZIO-101 ahead of schedule. Study results from the
oral
phase I trial and the ongoing phase II trials, in conjunction with
market
dynamics as a result of the launch of Revlamid ® for myeloma and Nexavar ®
for liver cancer, will determine the expected registration pathway
for
ZIO-101.

ZIO-201,
or isophosphoramide mustard (IPM), is a proprietary stabilized metabolite
of ifosfamide that is also related to cyclophosphamide. A patent
application for pharmaceutical composition has been filed in the
U.S. and
internationally. Cyclophosphamide and ifosfamide are alkylating agents.
The Company believes cyclophosphamide is the most widely used alkylating
agent in cancer therapy and it is used to treat breast cancer and
non-Hodgkin’s lymphoma. Ifosfamide has been shown to be effective in high
dose by itself or in combination in treating sarcoma and lymphoma
and is
approved by the FDA for testicular cancer. Although ifosfamide-based
treatment generally represents the standard of care for sarcoma,
it is not
licensed for this indication by the U.S. Food and Drug Administration.
Our
preclinical studies have shown that, in animal and laboratory models,
IPM
evidences activity against leukemia and solid tumors. These studies
also
indicate that ZIO-201 has a better pharmacokinetic and safety profile
than
ifosfamide or cyclophosphamide, offering the possibility of safer
and more
efficacious therapy with ZIO-201. Ifosfamide is metabolized to IPM.
In
addition to IPM, another metabolite of ifosfamide is acrolein, which
is
toxic to the kidneys and bladder. The presence of acrolein can mandate
the
administration of a protective agent called mesna, which is inconvenient
and expensive. Chloroacetaldehyde is another metabolite of ifosfamide
and
is toxic to the central nervous system, causing “fuzzy brain” syndrome for
which there is currently no protective measure. Similar toxicity
concerns
pertain to high-dose cyclophosphamide, which is widely used in bone
marrow
and blood cell transplantation. Because ZIO-201 is independently
active
without acrolein or chloroacetaldehyde metabolites, the Company believes
that the administration of ZIO-201 (and without the co-administration
of
mesna) may avoid many of the toxicities of ifosfamide and cyclophosphamide
without compromising efficacy. In some instances ZIO-201 appears
to show
activity in ifosfamide- and/or cyclophosphamide-resistant cancer
cells.
|
|
|
|
|
|
Phase
I and phase II testing of the intravenous (“IV”) form of ZIO-201 to treat
advanced sarcoma is ongoing in the U.S. IPM has been administered
without
the “uroprotectant” mesna and the toxicities associated with acrolein and
chloroacetaldehyde have not been observed. Kidney toxicity has been
identified as the dose limiting toxicity. The Company has reported
encouraging signs of clinical activity in the phase II study to date.
The
Company expects to complete this phase II study by year-end, which,
following discussions with appropriate health authorities, will serve
as a
basis for the contemplated registration trial. The Company also expects
to
file a U.S. Investigational New Drug Application for an oral form
of
ZIO-201 and to initiate trials in pediatric cancer and another solid
tumor
by the end of 2007.

ZIO-301
(indibulin) is a novel small molecular weight tubulin polymerization
inhibitor that has been acquired from Baxter Healthcare. An ongoing
phase
I study in the Netherlands and a newly initiated phase I study in
the U.S.
(with continuous dosing) are currently underway to evaluate safety,
pharmacokinetics (PK), maximum tolerated dose (MTD) and dose limiting
toxicity (DLT) in patients with advanced solid tumors. The Company
expects
to complete these and other studies as the basis for a phase II study
for
a solid tumor as well as a phase Ib combination study with another
agent
(as determined by ongoing preclinical evaluation) in the first quarter
of
2008.
The
microtubule component tubulin is one of the best established anti-tumor
targets in the treatment of cancer today. A number of anticancer
drugs are
on the market that target tubulin, for example paclitaxel (Taxol
®)
and the vinca alkaloid family (vincristine, vinorelbine). This class
of
agents is typically the mainstay of therapy in a wide variety of
indications. In spite of their effectiveness, the use of these drugs
is
associated with important toxicities, notably significant peripheral
neurotoxicity. In contrast, indibulin has not shown peripheral
neurotoxicity either in preclinical testing or in clinical study
to
date.
Indibulin
is an orally available compound. Preclinical studies demonstrate
significant and broad activity (including in taxane refractory and
multi-drug resistant cell lines and xenografts) and it is potentially
safer than other tubulin inhibitors (no neurotoxicity at curative
doses in
animals and in the ongoing phase I trials). At the current time,
the
Company anticipates pursuing a Fast Track development program in
a niche
indication following the completion of phase II testing. In addition,
the
availability of an IV formulation would further expand the market
opportunity and will be explored in 2007. The availability of an
oral
formulation of indibulin creates significant commercial opportunity,
since
no oral formulations of paclitaxel or related compounds are currently
on
the market.
