ZIO-101
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 (and organic arsenic in general)
is
considerably less toxic than inorganic arsenic, particularly with
regard
to heart toxicity. 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 use of an oral form of
the
drug.
|
Phase
I testing of the intravenous (IV) form of ZIO-101 is still ongoing
with
two safety and dose finding studies to be completed in the near future.
The Company has seen encouraging signs of clinical activity in both
of
these studies. The Company has completed the phase I portion of an
ongoing
phase I/II study in advanced multiple myeloma, also with encouraging
signs
of clinical activity. ZIOPHARM currently expects to complete multiple
phase II studies by year-end, which, following discussions with
appropriate health authorities, will serve as a basis for the contemplated
registration trial. The Company expects to file a U.S. Investigational
New
Drug Application for the clinical study of an oral form of ZIO-101
in
2007.

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 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 may avoid many of the toxicities
of
ifosfamide and cyclophosphamide without compromising efficacy. In
addition
to anticipated lower toxicity, ZIO-201 (and without the co-administration
of mesna) may have other advantages over ifosfamide. In preclinical
studies ZIO-201 likely cross-links DNA differently than ifosfamide
or
cyclophosphamide metabolites, resulting in a different activity profile.
Moreover, 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 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. Electrolyte imbalances similar to those seen
with
ifosfamide have occurred in the higher dose cohorts. The Company
has seen
encouraging signs of clinical activity in the phase I study. The
Company
has completed a phase I study in advanced sarcoma and a phase II
is
ongoing. ZIOPHARM expects to complete phase I and phase II studies
by
year-end, which, following discussions with appropriate health
authorities, will serve as a basis for contemplated registration
trial.
The Company also expects to file a U.S. Investigational New Drug
Application for an oral form of ZIO-201 in
2007.

ZIO-301
(indibulin) is a novel small molecular weight tubulin polymerization
inhibitor that has been acquired from Baxter Healthcare. A phase
I study
is currently underway in the Netherlands with indibulin to evaluate
safety, pharmacokinetics (PK), maximum tolerated dose (MTD) and dose
limiting toxicity (DLT) in patients with advanced solid tumors; an
Investigational New Drug Application has been filed in the United
States
and a phase I study is expected to initiate following FDA
review.
The
microtubule component tubulin is one of the more well established
anti-tumor targets in the treatment of cancer today. A number of
drugs are
on the market that target tubulin, for example paclitaxel (Taxol
®)
and the vinca alkaloid family (vincristine, vinorelbine). The use
of these
drugs is associated with important toxicities. Notably, paclitaxel
causes
significant peripheral neurotoxicity. In contrast, indibulin has
not shown
peripheral neurotoxicity either in preclinical testing or in the
clinic to
date.
This
class of agents is typically the mainstay of chemotherapy in a
wide
variety of cancer indications. Indibulin is an orally available
compound
with preclinical data that indicates significant and broad activity
(including 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
trial). At the current time, the Company anticipates pursuing a
Fast Track
development program in a niche indication following the completion
of
phase II testing. Potential initial indications would include but
are not
limited to bladder, head & neck, prostate, colorectal, and renal
cancer. Registration in one of these indications would then be
followed by
label expansion via trials that will have been initiated in anticipation
of registration. In addition, the availability of an IV formulation
would
further expand the market opportunity and will be explored in 2007.
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.
