ZIOPHARM Oncology, Inc.
Notes to Unaudited Financial Statements
 
1.
BASIS OF PRESENTATION AND OPERATIONS
 
The financial statements included herein have been prepared by ZIOPHARM Oncology, Inc. (“ZIOPHARM” or the “Company”) without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the accompanying unaudited financial statements include all adjustments (consisting of normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows of the Company at the dates and for the periods indicated. The unaudited financial statements included herein should be read in conjunction with the audited financial statements and the notes thereto included in ZIOPHARM Oncology, Inc.’s Form 10-KSB filed on February 13, 2007 for the fiscal year ended December 31, 2006.

ZIOPHARM is a development stage biopharmaceutical company that seeks to acquire, develop and commercialize, on its own or with other commercial partners, products for the treatment of important unmet medical needs in cancer.

The Company has operated at a loss since its inception in 2003 and has no revenues. The Company anticipates that losses will continue for the foreseeable future. At June 30, 2007, the Company’s accumulated deficit was approximately $44.8 million. The Company’s ability to continue operations after its current cash resources are exhausted depends on its ability to obtain additional financing and achieve profitable operations, as to which no assurances can be given. Cash requirements may vary materially from those now planned because of changes in the focus and direction of our research and development programs, competitive and technical advances, patent developments or other developments. Additional financing(s) will be required to continue operations as we exhaust our current cash resources and to continue our long-term plans for clinical trials and new product development.

On February 23, 2007, pursuant to subscription agreements between the Company and certain institutional and other accredited investors, the Company completed the sale of an aggregate of 5,910,049 shares of the Company’s common stock at a price of $5.225 per share in a private placement (the “2007 Offering”). In addition to these shares sold in the 2007 Offering, the Company also issued to each investor a five-year warrant to purchase, at an exercise price of $5.75 per share, an additional number of shares of common stock equal to 20 percent of the shares purchased by such investor in the 2007 Offering. In the aggregate, these warrants entitle investors to purchase an additional 1,182,015 shares of common stock. The Company estimated the fair value of these warrants at $4,724,169 using the Black-Scholes model, using an assumed risk-free rate of 4.71% and an expected life of 5 years, volatility of 93% and a dividend yield of 0%. The total gross proceeds resulting from the 2007 Offering was approximately $30.9 million, before deducting selling commissions and expenses.
 
The Company engaged Paramount BioCapital, Inc. (“Paramount”), Oppenheimer & Co. Inc., and Griffin Securities, Inc. (together, the “2007 Placement Agents”) as placement agents in connection with the 2007 Offering. In consideration for their services, the Company paid the 2007 Placement Agents aggregate cash commissions of $1,630,800 (of which $1,019,250 was paid to Paramount; see Note 4 - Related Party Transactions) and issued 5-year warrants to the 2007 Placement Agents and their designees to purchase an aggregate of 156,058 shares of the Company’s common stock at an exercise price of $5.75 per share. In connection with the 2007 Offering, the Company also made cash payments of $222,000 and issued 5-year warrants to purchase 21,244 shares of the Company's common stock, at an exercise price of $5.75 per share, to a financial consultant pursuant to the non-circumvention provision of a prior agency agreement. The Company estimated the fair value of these 177,302 warrants at $708,624 using the Black-Scholes model, using an assumed risk-free rate of 4.71% and an expected life of 5 years, volatility of 93% and a dividend yield of 0%.

Pursuant to the 2007 Offering, the Company agreed to use its best efforts to (i) file a registration statement covering the resale of the shares sold in the 2007 Offering and the common stock issuable upon exercise of the investor warrants and placement agent warrants issued in the 2007 Offering within 45 days following the closing date of the 2007 Offering, and (ii) use its reasonable commercial efforts to cause the registration statement to be effective within 120 days after such final closing date. Effective January 1, 2007, the Company adopted FASB Staff Position No. EITF 00-19-2 “Accounting for Registration Payment Arrangements” " FSP EITF 00-19-2". In accordance with FSP EITF 00-19-2, the Company accounts for obligations under registration payment arrangements in accordance with SFAS No. 5, "Accounting for Contingencies". Instruments subject to registration payments are accounted for without regard to the contingent obligation to make registration payments. As a result, the Company has determined that no contingent loss exists based on its history of timely annual, quarterly and registration filings. The Company intends to continue the timely compliance with all SEC filing requirements, which will keep the Company current and the shares registered.

BASIS OF PRESENTATION AND OPERATIONS …CONTINUED
 
 
With respect to each investor in the 2007 Offering, the Company also agreed to use its reasonable commercial efforts to cause the registration statement to remain effective until the earliest of (i) the date on which the investor may sell all of the shares and shares issuable upon exercise of the warrants then held by the investor pursuant to Rule 144(k) of the Securities Act of 1933 without regard to volume restrictions; and (ii) such time as all of the securities held by the investor and registered under the registration statement have been sold pursuant to a registration statement, or in a transaction exempt from the registration and prospectus delivery requirements of the Securities Act of 1933 under Section 4(1) thereof so that all transfer restrictions and restrictive legends are removed upon the consummation of such sale. The 2007 Placement Agents have been afforded equivalent registration rights as the investors in the 2007 Offering with respect to the shares issuable upon exercise of the placement agent warrants. Warrants issued in the 2007 Offering are classified as equity based on the determination that the penalty for failure to register is not uneconomic. On March 1, 2007, the Company filed a registration statement on Form S-3 with the Securities and Exchange Commission. The registration statement was declared effective on March 26, 2007, rendering the resale of the shares issued in the 2007 Offering registered under the Securities Exchange Act of 1933.

The results disclosed in the Statements of Operations for the three and six months ended June 30, 2007 are not necessarily indicative of the results to be expected for the full year.

RECENT ACCOUNTING PRONOUNCEMENTS
 
 
In July 2006, the Financial Accounting Standards Board issued Interpretation No. 48, Accounting for Uncertainty in Income Taxes. This Interpretation sets forth a recognition threshold and valuation method to recognize and measure an income tax position taken, or expected to be taken, in a tax return. The evaluation is based on a two-step approach. The first step requires an entity to evaluate whether the tax position would “more likely than not,” based upon its technical merits, be sustained upon examination by the appropriate taxing authority. The second step requires the tax position to be measured at the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate settlement. In addition, previously recognized benefits from tax positions that no longer meet the new criteria would no longer be recognized. The application of this Interpretation will be considered a change in accounting principle with the cumulative effect of the change recorded to the opening balance of retained earnings in the period of adoption. This Interpretation was effective for the Company on January 1, 2007. Adoption of this new Standard did not have a material impact on our financial position, results of operations or cash flows.

STOCK-BASED COMPENSATION
             
On January 1, 2006, the Company adopted Statement of Financial Accounting Standards No. 123(R) (“SFAS 123R”) Share-Based Payment, using the modified prospective method, which results in the provision of SFAS 123R only being applied to the consolidated financial statements on a going-forward basis (that is, the prior period results have not been restated). Under the fair value recognition provisions of SFAS 123R, stock-based compensation cost is measured at the grant date based on the value of the award using the Black Scholes Model and is recognized as expense over the service period. Previously, the Company had followed Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employee, and related interpretations which resulted in account for employee share options at their intrinsic value in the financial statements.

The Company recognized the full impact of its share-based payment plans in the statements of operations for the three and six months ended June 30, 2007 and 2006 under SFAS 123R and did not capitalize any such costs on the balance sheets. The following table presents share-based compensation expense included in the Company’s statement of operations:

STOCKHOLDERS’ EQUITY

On February 23, 2007, pursuant to subscription agreements between the Company and certain institutional and other accredited investors, the Company completed the 2007 Offering in which the Company’s sold an aggregate of 5,910,049 shares of the Company’s common stock at a price of $5.225 per share. The total gross proceeds resulting from the 2007 Offering was approximately $30.9 million, before deducting selling commissions and expenses. Following the completion of the 2007 Offering, the Company has 21,182,948 shares of common stock outstanding.
 
5.
RELATED PARTY TRANSACTIONS
 
In connection with the 2007 Offering, on February 23, 2007, the Company paid Paramount cash commissions equal to 6% of the gross proceeds from the sale of the shares sold by Paramount in the 2007 Offering, resulting in a cash payment of approximately $1,019,250. In addition, the Company issued 5-year warrants to the placement agents in the 2007 Offering and their designees to purchase an aggregate of 177,302 shares (3% of the shares sold in the 2007 Offering) of the Company’s common stock at an exercise price of $5.75 per share, of which  97,536 were issued to Paramount.

Timothy McInerney, who is a member of the Board of Directors of the Company, was a full-time employee of Paramount from 1992 through March 2007. In addition, Michael Weiser, a current member of the Board of Directors of the Company, was a full-time employee of Paramount from 1998 through November 2006.

STOCK OPTION PLAN
 
The Company has adopted the 2003 Stock Option Plan (the “Plan”), under which the Company had initially reserved for the issuance of 1,252,436 shares of its Common Stock. The Plan was approved by the Company’s stockholders on December 21, 2004. On April 25, 2007 and April 26, 2006, the date of the Company’s annual stockholders meetings, the Company’s stockholders approved amendments to the Plan increasing the total shares reserved by 2,000,000 and 750,000 shares, respectively, for a total of 4,002,436 shares.

As of June 30, 2007, there were 2,254,044 shares that are issuable under its 2003 Stock Option Plan upon exercise of outstanding options to purchase common stock. As of June 30, 2007, the Company had issued to our employees outstanding options to purchase up to 1,893,620 shares of the Company’s common stock. In addition, the Company has issued to our directors options to purchase up to 360,174 shares of the Company’s common stock, as well as options to a consultant in connection with services rendered to purchase up to 250 shares of the Company’s common stock.

STOCK OPTION PLAN ...CONTINUED
 
Currently, stock options are granted with an exercise price equal to the closing market price of the Company’s common stock on the day before the date of grant. Stock options to employees generally vest ratably in annual installments over three years and have contractual terms of ten years. Stock options to directors generally vest ratably in annual installments over two or three years and have contractual terms of ten years. Stock options are valued using the Black-Scholes option valuation method and compensation is recognized based on such fair value over the period of vesting on a straight-line basis. The Company has also reserved an aggregate of 70,934 additional shares for issuance under options granted outside of the 2003 Stock Option Plan. As of June 30, 2007, there are 70,934 options outstanding and 25,111 options exercisable that are outside of the 2003 Stock Option Plan. During the six months ended June 30, 2007, the Company recorded a $120,492 stock compensation expense in connection with the Company achieving a predetermined development milestone, which triggered the vesting of 25,111 of the options granted outside of the 2003 Stock Option Plan.

During the three and six months ended June 30, 2007, the Company granted 410,750 and 429,250 options. Also during the three and six months ended June 30, 2007, the Company cancelled 10,000 and 88,241 options, while no options were exercised, under the 2003 Stock Option plan, in this period. During the three and six months ended June 30, 2006, 637,180 options were granted, none were cancelled and no options were exercised. During the six months June 30, 2007, the Company entered into a termination agreement with an employee which accelerated the vesting of an employee’s previously granted options. The Company recorded a charge of $41,663 in the six months ended June 30, 2007 as a result of the acceleration. These accelerated options have expired without exercise and the Company cancelled the options in the six month period ending June 30, 2007.
 
The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model. Assumptions regarding volatility, expected term, dividend yield and risk-free interest rate are required for the Black-Scholes model. Volatility and expected term assumptions are based on comparable Company’s historical experience. The risk-free interest rate is based on a U.S. treasury note with a maturity similar to the option award’s expected life. The assumptions used at June 30, 2007 are as follows, volatility of 91 - 93%, expected life of approximately 5 years, a dividend yield of 0% and a risk-free interest rate of 4.39 - 5.03%.

Item 2.  MANAGEMENT’S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION.

Note Regarding Forward-Looking Statements
       
This Quarterly Report on Form 10-QSB contains statements that are not historical, but are forward-looking in nature, including statements regarding the expectations, beliefs, intentions or strategies regarding the future. In particular, the “Management’s Discussion and Analysis and Plan of Operation” sections in Part I, Item 2 of this Quarterly Report includes forward-looking statements that reflect our current views with respect to future events and financial performance. We use words such as we “expect,” “anticipate,” “believe,” and “intend” and similar expressions to identify forward-looking statements. A number of important factors could, individually or in the aggregate, cause actual results to differ materially from those expressed or implied in any forward-looking statements. Such factors include, but are not limited to, our ability to develop or commercialize our product candidates successfully, our ability to obtain additional financing, our ability to develop and maintain customer relationships, regulatory developments relating to our and our customers’ products, and our ability to protect our proprietary technology. Other risks are described under the section entitled “Risk Factors” in our Current Report on Form 10-KSB filed on February 13, 2007.

Overview:
 
ZIOPHARM Oncology, Inc. is a biopharmaceutical company that is seeking to develop and commercialize a diverse, risk-sensitive portfolio of in-licensed cancer drugs that address unmet medical needs. Our principal focus is on the licensing and development of proprietary drug candidate families that are related to cancer therapeutics that are already on the market or in development. We believe this strategy will result in lower risk and expedited drug development programs. We expect to commercialize our products on our own in North America but recognize that promising clinical trial results in cancers with a high incidence and prevalence might also be addressed in a commercial partnership with another company with the requisite financial resources. Currently, we are in phase I and II studies for three product candidates known as ZIO-101, ZIO-201 and ZIO-301:
 
 
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.
 
12

 
Overview…Continued

 
 
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.

Overview…Continued

 
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.
 
Although we intend to continue with clinical development of ZIO-101 for various indications, ZIO-201 for advanced sarcoma and other indications, and ZIO-301 in solid tumors, the successful development of our product candidates is highly uncertain. Product development costs and timelines can vary significantly for each product candidate and are difficult to accurately predict. Various statutes and regulations also govern or influence the manufacturing, safety, labeling, storage, record keeping and marketing of each product. The lengthy process of seeking approval and the subsequent compliance with applicable statutes and regulations require the expenditure of substantial resources. Any failure by us to obtain, or any delay in obtaining, regulatory approvals could materially adversely affect our business. To date, we have not received approval for the sale of any drug candidates in any market and, therefore, have not generated any revenues from our drug candidates.
 
14

 
Plan of Operation
 
Our plan of operation for the next twelve months is to continue implementing our business strategy, including the clinical development of our three lead product candidates, ZIO-101, ZIO-201 and ZIO-301. We also intend to expand our drug candidate portfolio by seeking additional drug candidates through in-licensing arrangements. We expect our principal expenditures during those 12 months to include:
 
Fees and milestone payments required under the license agreements relating to our existing product candidates;
 
 
Clinical trial expenses, including the costs incurred with respect to the conduct of clinical trials for ZIO-101, ZIO-201 and ZIO-301, and preclinical costs associated with back-up candidates;
 
 
Costs related to the scale-up and manufacture of ZIO-101, ZIO-201 and ZIO-301;
 
 
Rent for our facilities; and
 
 
General corporate and working capital, including general and administrative expenses.
 
As part of our plan for additional employees, we anticipate hiring several additional full-time employees in the regulatory, clinical and finance functions. In addition, we intend to use senior advisors, consultants, clinical research organizations and third parties to perform certain aspects of product development, manufacturing, clinical and preclinical development, and regulatory and quality assurance functions.

At our current and desired pace of clinical development of ZIO-101, ZIO-201, ZIO-301, and other back-up candidates and ongoing in-licensing efforts over the next 12 months we expect to spend approximately $2.5 million on preclinical and regulatory expenses, $14.5 million on clinical expenses (including clinical trials and milestone payments that we expect to be triggered under the license agreements relating to our product candidates), approximately $7.5 million on manufacturing costs, approximately $650,000 on facilities, rent and other facilities related costs, and approximately $7.4 million on general corporate and working capital. With the proceeds from the common stock offering of February 23, 2007, we believe that we currently have sufficient capital to fund development and commercialization activities of ZIO-101, ZIO-201, and ZIO-301 into February of 2009.

Product Candidate Development and Clinical Trials

ZIO-101. ZIO-101 (darinaparsin), organic arsenic, is being developed presently to treat advanced myeloma, other hematological malignancies and liver cancer and three separate phase II trials have been initiated. A phase I trial with an oral form of ZIO-101 has just opened for enrollment. We will continue to explore different indications, dosing schedules and forms and formulations. Preclinical development will continue with back-up compounds and additional compounds are being synthesized. Technology transfer and scale-up for the commercial manufacture of the active pharmaceutical ingredient, its lyophilization, and final product specification for both the IV and oral forms will continue through the period to a registration trial.

ZIO-201. ZIO-201, stabilized isophosphoramide mustard or IPM, is being developed presently to treat advanced sarcoma. A phase II trial in advanced sarcoma is well underway. Other trials, including different indications and an oral form of administration are in the advanced planning stages. We expect to initiate a registration trial in advanced sarcoma following the completion of the phase II study. Technology transfer and scale-up for the commercial manufacture of the active pharmaceutical ingredient, its lyophilization, and final product specification will continue. Preclinical development will continue with back-up analogues.
 
ZIO-301. ZIO-301 (indibulin), a novel anti-cancer agent that targets mitosis like the taxanes, is available as an oral form and potentially an intravenous form. The oral form is currently in a phase I trial in Europe and a separate trial in the United States (using continuous dosing) and phase II testing is expected to initiate in the first half of 2008.
 
Results of Operations
 
Revenues.  We had no revenues for either of the three and six-month periods ended June 30, 2007 and 2006.

Research and development expenses.  For the three-month period ended June 30, 2007, research and development expenses increased by $1,667,491, or 62.2%, to $4,347,610 from $2,680,119 in the three-month period ended June 30, 2006. Increased research and development expenses in the current year period is primarily attributable to an approximately $678,000 increase in the cost of clinical trial, regulatory and related expenses as well as a $625,000 milestone payment for the successful US IND application for ZIO-301. The increase in expenses is also attributable to an increase of approximately $92,000 in stock compensation expense related to stock options and approximately $197,000 in employee related costs. For the six-month period ended June 30, 2007, research and development expenses increased by $3,325,754, or 74.8%, to $7,774,123 from $4,448,369 in the six-month period ended June 30, 2006. Increased research and development expenses in the current year period are primarily attributable to an approximately $1,167,000 increase in the cost of clinical trials, regulatory, and preclinical related expenses and an increase of approximately $667,000 in manufacturing related costs. Additionally the increase is due to a $625,000 milestone payment for the successful US IND application for ZIO-301. The increase in expenses is also attributable to an increase of approximately $207,000 in stock compensation expense related to stock options and approximately $487,000 in payroll and employee related costs.

General and administrative expenses. For the three-month period ended June 30, 2007, general and administrative expenses decreased by $160,488, or 5.3%, to $2,847,973 from $3,008,461 in the three-month period ended June 30, 2006. The decrease is attributable to a decrease of approximately $1.6 million in stock compensation expense related to stock options recorded in the three months ended June 30, 2007 compared to the prior year periods, which was offset by an increase of approximately $300,000 in financial consulting costs, approximately $13,000 for investor relations services, approximately $157,000 in patent related legal fees, approximately $95,000 in legal, accounting, and filing fee costs, and approximately $473,000 in payroll and employee related costs . For six month period ended June 30, 2007, general and administrative expenses increased by $324,902, or 7.2%, to $4,837,991 from $4,513,089 in the six-month period ended June 30, 2006. The increase is attributable to an increase of approximately $300,000 in financial consulting costs, approximately $197,000 for investors relations services, approximately $282,000 in legal and patent related fees, approximately $101,000 in rent and related facility expenses, and approximately $739,000 in payroll and employee related costs . These increases were offset by an approximate $1.7 million decrease in stock compensation expense related to stock options recorded in the six months ended June 30, 2006.

Other income (expense). Other income increased by $326,512, or 100.8%, to $650,382 in the three-month period ended June 30, 2007 from $323,870 recorded in the three-month period ended June 30, 2006. Other income during the three month periods ended June 30, 2007 and 2006, respectively, was comprised of interest income. Other income increased by $648,519, or 171.6% to $1,026,277 in the six-month period ended June 30, 2007 from $377,708 recorded in the six-month period ended June 30, 2006. Other income during the six month periods ended June 30, 2007 and 2006, respectively, was comprised of interest income. The increase is due to higher cash balances from the February 23, 2007 private placement.

Net income (loss). For the reasons described above, the net loss increased by $1,180,491, or 22.0%, to $(6,545,201) in the three month period ended June 30, 2007 from $(5,364,710) for the same period of 2006. The net loss increased $3,002,137, or 35.0%, to $(11,585,887) in the six month period ended June 30, 2007 from $(8,583,750) for the same period of 2006.

Liquidity and Capital Resources

As of June 30, 2007, we had approximately $46.7 million in cash and cash equivalents. With the proceeds from our 2007 common stock offering, which was completed on February 23, 2007, we believe we currently have sufficient capital to fund development and commercialization activities of ZIO-101, ZIO-201, and ZIO-301  into February of 2009. Because our business does not generate any cash flow, however, we will need to raise additional capital to continue development of the product candidates beyond that time or to fund development efforts related to new product candidates. We anticipate raising such additional capital by either borrowing money or by selling shares of our capital stock. To the extent additional capital is not available when we need it, we may be forced to abandon some or all of our development and commercialization efforts, which would have a material adverse effect on the prospects of our business. Further, our assumptions relating to the expected costs of development and commercialization and timeframe for completion are dependent on numerous factors other than available financing, including significant unforeseen delays in the clinical trial and regulatory approval process, which could be extremely costly. In addition, our estimates assume that we will be able to enroll a sufficient number of patients in each clinical trial.
 
The Company anticipates that losses will continue for the foreseeable future. At June 30, 2007, the Company’s accumulated deficit was approximately $44.8 million. The Company has incurred significant losses from operations and has an accumulated deficit that raises substantial doubt about the Company’s ability to continue as a going concern. The Company’s ability to continue operations after its current cash resources are exhausted depends on its ability to obtain additional financing and achieve profitable operations, as to which no assurances can be given.

Liquidity and Capital Resources…Continued
 
Our actual cash requirements may vary materially from those now planned because of a number of factors including:

·    
Changes in the focus and direction of our research and development programs, including the acquisition and pursuit of development of new product candidates;

·    
Competitive and technical advances;

·    
Costs of commercializing any of the product candidates; and

·    
Costs of filing, prosecuting, defending and enforcing any patent claims and any other intellectual property rights; or other developments.

In order to continue our long-term plans for clinical trials and new product development, we will need to raise additional capital to continue to fund our research and development as well as operations after we exhaust our current cash resources. We expect to finance our cash needs through the sale of equity securities and possibly strategic collaborations or debt financings or through other sources that may be dilutive to existing stockholders. There can be no assurance that any such financing can be realized by the Company, or if realized, what the terms thereof may be, or that any amount that the Company is able to raise will be adequate to support the Company’s working capital requirements until it achieves profitable operations. If we are unable to raise additional funds when needed, we may not be able to market our products as planned or continue development and regulatory approval of our products, or we could be required to delay, scale back or eliminate some or all our research and development programs.

Liquidity and Capital Resources…Continued

Since inception, our primary source of funding for our operations has been the private sale of our securities. During the three months ended March 31, 2007, we received gross proceeds of approximately $30.9 million ($28,970,915 net of cash issuance costs) as a result of a sale of an aggregate of 5,910,049 shares of the Company’s common stock at a price of $5.225 per share in a private placement (the “2007 Offering”). In addition to the shares, the Company also issued to each investor a five-year warrant to purchase, at an exercise price of $5.75 per share, an additional number of shares of common stock equal to 20 percent of the shares purchased by such investor in the 2007 Offering. In the aggregate, these warrants entitle investors to purchase an additional 1,182,015 shares of common stock. The Company estimated the fair value of these warrants at $4,724,169 using the Black-Scholes model, using an assumed risk-free rate of 4.71% and an expected life of 5 years, volatility of 93% and a dividend yield of 0%. The Company engaged Paramount BioCapital, Inc. (“Paramount”), Oppenheimer & Co. Inc., and Griffin Securities, Inc. (together, the “2007 Placement Agents”) as placement agents in connection with the 2007 Offering. In consideration for their services, the Company paid the 2007 Placement Agents aggregate cash commissions of $1,630,800 and issued 5-year warrants to the 2007 Placement Agents and their designees to purchase an aggregate of 156,058 shares of the Company’s common stock at an exercise price of $5.75 per share.  In connection with the 2007 Offering, the Company also made cash payments of $222,000 and issued 5-year warrants to purchase 21,244 shares of the Company's common stock, at an exercise price of $5.75 per share, to a financial consultant pursuant to the non-circumvention provision of a prior agency agreement The Company estimated the fair value of the 177,302 warrants at $708,624 using the Black-Scholes model, using an assumed risk-free rate of 4.71% and an expected life of 5 years, volatility of 93% and a dividend yield of 0%. The total gross proceeds resulting from the 2007 Offering was approximately $30.9 million, before deducting selling commissions and expenses.

During the year ended December 31, 2006, we received gross proceeds of approximately $37 million ($34,280,121 net of cash issuance costs) as a result of the sale of an aggregate of 7,991,256 shares of common stock, at a price of $4.63 per share, in a private offering (the “2006 Offering”) that was completed on May 3, 2006. In addition to the Shares, the Company also issued to each investor a five-year warrant to purchase, at an exercise price of $5.56 per share, an additional number of shares of common stock equal to 30 percent of the shares purchased by such investor in the 2006 Offering. In the aggregate, these warrants entitle investors to purchase an additional 2,397,392 shares of common stock. The Company engaged Paramount BioCapital, Inc. and Griffin Securities, Inc. (the “2006 Placement Agents”) as co-placement agents in connection with the 2006 Offering. In consideration for their services, the Company paid the 2006 Placement Agents and certain selected dealers engaged by the 2006 Placement Agents aggregate cash commissions of $2,589,966 and issued 7-year warrants to the 2006 Placement Agents and their designees to purchase an aggregate of 799,126 shares at an exercise price of $5.09 per share. The Company also agreed to reimburse the 2006 Placement Agents for their accountable expenses incurred in connection with the Offering.

During the year ended December 31, 2005, we received $4,815 proceeds from the exercise of stock options and gross proceeds of approximately $18.1 million ($16.8 net of issuance costs) as a result of the sale by ZIOPHARM, Inc. of Series A Convertible Preferred Stock in a private placement transaction. During the twelve months ended December 31, 2004, we received proceeds of approximately $4.5 million as a result of the sale by ZIOPHARM, Inc. of common stock in a private placement transaction. The Company engaged Paramount as a placement agent in the Series A Convertible Preferred Stock offering and granted Paramount a right of first refusal to act as the placement agent for the private sale of the Company’s securities through May 31, 2008. On December 18, 2006 the Company paid Paramount a cash settlement of $180,000 in exchange for Paramount’s agreement to terminate this right of first refusal.

At June 30, 2007, working capital was approximately $43.7 million, compared to working capital of approximately $25.9 million at December 31, 2006. The increase in working capital reflects the proceeds from the 2007 Offering offset by the use of funds for operations.

Capital expenditures were approximately $392,000 for the six months ended June 30, 2007. We anticipate capital expenditures of approximately $750,000 for the fiscal year ended December 31, 2007.

Critical Accounting Policies and Significant Estimates

The preparation of financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, including those related to accounting for stock-based compensation and research and development activities. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under difference assumptions or conditions.

Research and Development

Research and development expenses consist primarily of salaries and related personnel costs, fees paid to consultants and outside service providers for preclinical, clinical, and manufacturing development, legal expenses resulting from intellectual property prosecution and organizational affairs and other expenses relating to the design, development, testing, and enhancement of our product candidates. We expense our research and development costs as they are incurred. General and administrative expenses consist primarily of salaries and related expenses for executive, finance and other administrative personnel, recruitment expenses, professional fees and other corporate expenses, including business development and general legal activities.

19

 
Stock-based compensation

Our results include non-cash compensation expense as a result of the issuance of stock option and warrant grants. On January 1, 2006, the Company adopted Statement of Financial Accounting Standards No. 123(R) (“SFAS 123R”) Share-Based Payment, using the modified prospective method, which results in the provision of SFAS 123R only being applied to the consolidated financial statements on a going-forward basis (that is, the prior period results have not been restated). Under the fair value recognition provisions of SFAS 123R, stock-based compensation cost is measured at the grant date based on the value of the award using the Black Scholes Model and is recognized as expense over the service period. Previously, the Company had followed Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees , and related interpretations which resulted in account for employee share options at their intrinsic value in the financial statements. The Company’s most critical estimates consist of accounting for stock-based compensation.

Off-Balance Sheet Arrangements
 
We do not have any “off-balance sheet agreements,” as that term is defined by SEC regulation.

Item 3.  CONTROLS AND PROCEDURES   
 
Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) or 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the Exchange Act), as of the end of the period covered by this report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective.
 
There have been no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Rule 13a-15 or 15d-15 promulgated under the Exchange Act that occurred during the last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
