REQORSA is injected intravenously and specifically targets cancer cells. Cancer cells have elevated metabolism compared to healthy cells and as a result, are negatively charged compared to healthy cells, which are generally charge neutral. REQORSA is designed to deliver the functioning TUSC2 gene to cancer cells while minimizing uptake by normal tissue.

Our diabetes product candidates are currently being evaluated and optimized in preclinical studies at the University of Pittsburgh. GPX-002 is being developed using the same construct for the treatment of both Type 1 diabetes and Type 2 diabetes.

GPX-002 for Type 1 diabetes is designed to work by transforming alpha cells in the pancreas into functional beta-like cells, which can produce insulin but may be distinct enough from beta cells to evade the body’s immune system.

In a similar approach, GPX-002 for Type 2 diabetes (formerly known as GPX-003), where autoimmunity is not at play, is believed to work by replenishing and rejuvenating exhausted beta cells that make insulin.

A subset of NSCLC patients carry a mutation in EGFR, which makes their tumors sensitive to EGFR tyrosine kinase inhibitors (“EGFR TKIs”). The two most common are referred to as exon 19 deletion and exon 21 substitution. Several pharmacological and biological approaches, including EGFR TKIs, have been developed specifically to block activated EGFR for cancer therapy.

TUSC2 functions to mediate apoptosis in cancer cells through interaction with Apaf1 and also down-regulates multiple tyrosine kinases that control cell growth, including EGFR, AKT, platelet-derived growth factor receptor (“PDGFR”), c-Kit, and c-Abl. In normal cells, the proteins involved in the PI3K/AKT/mTOR pathway play an important role in cellular function and cellular trafficking.

Operation of the ONCOPREX Delivery System The cationic (positive) charge of the lipoplexes helps to target cancer cells, which have a slight negative charge due to their high glycolytic rate. A Phase 1 clinical trial showed that intravenous REQORSA therapy selectively and preferentially targeted tumor cells, resulting in anticancer activity.

While the beta cell produces insulin, the only blood glucose-lowering hormone of the body, the alpha cell releases glucagon, which elevates blood glucose. 21 In people with Type 1 diabetes, however, beta cells are destroyed by the immune system and no longer secrete insulin, leading to an absolute deficit of insulin.

The extended PFS of each of these patients is consistent with long-term PFS seen in several patients in prior early stage clinical trials of REQORSA and is not expected with treatment with Tagrisso alone after progression on Tagrisso. REQORSA administration was generally well tolerated and there were no DLTs.

Our study in SCLC builds on the preclinical data showing that REQORSA enhances the immune response to cancer, and that the combination of REQORSA and immune checkpoint inhibitors demonstrates a therapeutic benefit over immune checkpoint inhibitors alone. Immune checkpoint inhibitors, such as Tecentriq, have recently been approved for use in ES-SCLC.

Data from these clinical and preclinical studies indicates that combining REQORSA with these other therapies yields results more favorable than either these therapies or REQORSA alone, with minimal side effects relative to other lung cancer drugs, thereby potentially making REQORSA a therapy complementary to these cancer treatments. 10 Acclaim-1 As described above, in January 2020, we received Fast Track Designation from the FDA for use of REQORSA in combination with TKI Tagrisso for the treatment of NSCLC patients with EGFR mutations whose tumors progressed after treatment with Tagrisso.

REQORSA targeting is partly due to the attraction of opposite charges (REQORSA has a positive charge, normal cells no charge, and most cancer cells have a negative charge), and partly due to enhanced endocytosis by tumor cells, and is enhanced by the leakiness that is characteristic of tumor vasculature.

In the Phase 1 Monotherapy Trial, REQORSA was injected intravenously in stage IV (metastatic) lung cancer patients who had received traditional platinum combination chemotherapy but had tumor progression at the time of entry into the study. Thirty-one subjects were treated at six dose levels. Seventy percent of subjects had received two or more prior chemotherapy regimens.

Cancer results from genetic mutations. Mutations that lead to cancer are usually present in two major classes of genes: oncogenes, which are involved in functions such as signal transduction and transcription; and tumor suppressor genes, which play multiple roles in governing cell growth and proliferation. Transduction is the process by which chemical and physical signals are transmitted into cells.

Risks Related to Development and Commercialization of Our Current and Future Product Candidates ● Our success depends greatly on the success of our development of REQORSA for the treatment of NSCLC and SCLC, and our other product candidates, including GPX-002 for the treatment of diabetes. ● If we are unable to secure contract manufacturers with capabilities to produce the products that we require, we could experience delays in conducting our planned clinical trials. ● Negative public opinion and increased regulatory scrutiny of gene therapy and genetic research may damage public perception of our current and potential product candidates or adversely affect our ability to conduct our business or obtain regulatory approvals for our current and potential product candidates. ● Conducting successful clinical studies may require the enrollment of large numbers of patients, and suitable patients may be difficult to identify and recruit. ● Delays in the commencement, enrollment and completion of clinical trials could result in increased costs to us and delay or limit our ability to obtain regulatory approval for REQORSA and other current or future product candidates. ● Fast track designation of our products by FDA and designation under any other FDA expedited development program may not actually lead to a faster development or regulatory review or approval process, nor will it assure FDA approval of our product candidates. ● We may not be able to obtain or maintain orphan drug designation or exclusivity for our product candidates. ● A product candidate can fail at any stage of preclinical and clinical development. ● REQORSA®, GPX-002, and any other product candidate we advance through clinical trials may not have favorable results in later clinical trials or receive regulatory approval.
