NOTE 1 – BACKGROUND
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 focused on the development of prodrug cancer therapeutics for the treatment of solid tumors. A prodrug is an inactive precursor of a drug that is converted into its active form only at the site of the tumor. Our 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.
Our major focus for the next twelve to eighteen months is the (i) development of a clinical protocol for and enrollment into a dose optimization trial of single-agent mipsagargin followed by a clinical trial in patients with advanced HCC, (ii) completion of the non-clinical study of mipsagargin in combination with Nexavar ® in liver tumor models (iii) development of a Phase 1b clinical protocol of mipsagargin in combination with Nexavar ® in patients with Nexavar ® naïve HCC in anticipation of positive non-clinical data, (iv) completion of a nonclinical study of mipsagargin in combination with paclitaxel and in combination with DC101 (Cyramza surrogate antibody) in gastric cancer tumor models, (v) ongoing business development discussions with potential development partners, (vi) evaluation of mipsagargin (single agent and in combination with standard of care) in nonclinical models of other solid tumor types that express PSMA, (vii) evaluate our PSMA-peptide prodrug technology with new linkers and new payloads in non-clinical models, and (viii) explore collaborations utilizing mipsagargin in new, non-clinical solid tumor models with leading researchers in the oncology field.
A review of ongoing investigator led clinical trials resulted in the discontinuation of studies to realign with our mipsagargin clinical strategy of prioritizing smaller, potentially faster to market indications, pursuing mipsagargin combinations with standard of care, and conducting key clinical trials as company sponsored studies. Larger market indications will be pursued subsequently. The investigator led studies that were discontinued during the realignment were G202-004 (An Open-Label, Single-Arm, Phase II Study to Evaluate the Efficacy, Safety and CNS Exposure of G-202 in Patients with Recurrent or Progressive Glioblastoma), G202-005 (An Open-Label, Single-Arm, Phase II Study to Evaluate the Safety and Activity of G-202 Administered in the Neoadjuvant Setting Followed by Radical Prostatectomy in Patients with Adenocarcinoma of the Prostate) and G202-006 (An Open-Label, Single-Arm, Phase II Study to Evaluate the Safety and Activity of G-202 in Patients with Clear Cell Renal Cell Carcinoma that Expresses PSMA); all studies were closed December 2016
In January 2015, we presented preliminary results from our Phase II study of mipsagargin in advanced liver cancer patients, and these data were updated in May 2015 when we received a final clinical study report. We consider the results of the study to be positive, with 41% of evaluable patients demonstrating a reduction in tumor burden, 63% of treated patients having stable disease, and a median time to progression of 4.5 months. Additionally, the trial demonstrated that mipsagargin is effective at destroying the vascularity of solid tumors thereby starving the tumor. These results support our plans to continue the development of mipsagargin for patients with liver cancer, as well as proceed with our development strategy in other indications.
In January 2017, we announced the initiation of development programs focused on mipsagargin combination therapies with the start of the first nonclinical combination study of mipsagargin in combination with Nexavar® in HCC tumor models.
In February 2017, we announced the start of our second nonclinical combination study of mipsagargin in combination with paclitaxel in gastric cancer tumor models. In addition, the Company plans to evaluate Mipsagargin in combination with DC101 (Cyramza® surrogate antibody). This study is on hold.
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 completion of the nonclinical studies of mipsagargin in HCC and gastric cancer and continuing business development discussions with potential development partners.
