Organization, Consolidation and Presentation of Financial Statements [Abstract]  



Inspyr Therapeutics, Inc. (“we”, “us”, “our company”, “our”, “Inspyr” or the “Company”) was formed under the laws of the State of Delaware in November 2003, and has its principal office in Westlake Village, California. We are an early-stage, pre-revenue, pharmaceutical company focused on the discovery and development of prodrug cancer therapeutics for the treatment of solid tumors, including brain, liver, prostate and other cancers. We plan to develop a series of therapies based on our target-activated prodrug technology platform.


Effective August 1, 2016, pursuant to a certificate of amendment to our amended and restated certificate of incorporation, we changed our corporate name from GenSpera, Inc. to Inspyr Therapeutics, Inc. Effective August 1, 2016, our common stock ceased trading under the symbol “GNSZ” and began trading under the symbol NSPX on August 2, 2016.


Effective November 17, 2016 at 5:00 p.m. Eastern Time, we effected a one (1) for thirty (30) reverse stock split of our common stock. Accordingly, each of our shareholders received one (1) new share of common stock for every thirty (30) shares of common stock such shareholder held immediately prior to the effective time of the reverse split. The reverse stock split affected all of our issued and outstanding shares of common stock as well as the number of shares of common stock underlying stock options, warrants and other exercisable or convertible instruments outstanding at the effective time of the reverse split. The reverse split also has the effect of proportionately increasing the applicable conversion or exercise price of such convertible securities. The shareholders received no fractional shares and instead had every fractional share rounded up to the next whole number.


All references to common stock, share and per share amounts have been retroactively restated to reflect the 1:30 reverse stock split as if it had taken place as of the beginning of the earliest period presented.


We are a clinical-stage, pre-revenue, pharmaceutical company primarily focused on the development of therapeutics for the treatment of patients with cancer. Our therapeutics include a prodrug, mipsagargin and, through our acquisition of Lewis and Clark Pharmaceuticals, Inc., a pipeline of small molecule adenosine receptor modulators.


A prodrug is an inactive precursor of a drug that is converted into its active form only at the site of the tumor. The prodrug technology platform combines a powerful cytotoxin with a patented prodrug delivery system that targets the release of the drug within the tumor. We believe our cancer prodrugs have the potential to provide a targeted therapeutic approach to a broad range of solid tumors with fewer side effects than those related to current cytotoxic chemotherapy treatments. Our lead drug candidate, mipsagargin, has completed an open label single arm Phase II clinical trial in patients with advanced hepatocellular carcinoma (HCC) or liver cancer.


The adenosine receptor modulators include A2B antagonists, A2A antagonists, dual A2A/A2B antagonists, and A2A agonists that have broad development applicability including indications within immuno-oncology and inflammation. Adenosine is implicated in immunosuppression in the tumor microenvironment. Adenosine receptor antagonists may boost the host immune response against the tumor as a single-agent and in combination with other existing immuno-oncology agents leading to enhanced tumor killing and inhibition of metastasis. Adenosine also has anti-inflammatory properties in the acute and chronic setting. Adenosine receptor agonists may promote a decreased inflammatory response and can potentially treat a broad range of inflammatory and autoimmune based diseases and conditions (e.g., rheumatoid arthritis, joint injury, Crohn’s disease, psoriasis) as well as improve wound healing and decrease pain.  


Our major focus for the next twelve to eighteen months is the (i) further characterization of the current pipeline of A2B antagonists and dual A2A/A2B antagonists leading to an Investigative New Drug or IND enabling studies, (ii) further characterization of the A2A agonists, (iii) licensing and/or partnering the A2B antagonists, A2A antagonists, dual A2A/A2B antagonists, and A2A agonists for further development, (iv) through our newly acquired adenosine receptor chemistry technology platform, continue to produce next generation adenosine receptor modulators, (v) pursue licensing and/or partnering of mipsagargin, (vi) conduct a clinical study of mipsagargin in patients with advanced HCC, and (vii) explore collaborations utilizing mipsagargin in new, non-clinical solid tumor models with leading researchers in the oncology field.


While we believe that the data from our nonclinical and completed clinical studies appear promising, the outcome of our ongoing or future studies may ultimately be unsuccessful.


Our ability to execute our business plan is dependent on the amount and timing of cash, if any, that we are able to raise. Should we not raise sufficient funds to execute our business plan, our priority is the continued production of adenosine receptor modulator products for any existing material transfer agreements and continuing business development discussions with potential development partners.
