The Next Generation Anthracycline
Annamycin is a unique next-generation liposome formulated anthracycline (also referred to in literature as “L-Annamycin”) that has been designed to eliminate cardiotoxicity and avoid the multidrug resistance mechanisms that often defeat currently approved anthracyclines. In animal models designed to test for cardiotoxicity, Annamycin was shown to be non-cardiotoxic and in human clinical trials focused on leukemia, it showed fewer dose-limiting toxicities than are normally experienced with doxorubicin (one of the leading first-line anthracyclines used for induction therapy).
First-In-Class p-STAT3 Inhibitor
WP1066 is one of several Immune/Transcription Modulators, designed to stimulate the immune response to tumors by inhibiting the errant activity of Regulatory T-Cells (TRegs) while also inhibiting key oncogenic transcription factors, including p-STAT3 (phosphorylated signal transducer and activator of transcription 3), c-Myc (a cellular signal transducer named after a homologous avian virus called Myelocytomatosis) and HIF-1α (hypoxia inducible factor 1α). These transcription factors are widely sought targets that are believed to contribute to an increase in cell survival and proliferation, and the angiogenesis (coopting vasculature for blood supply), invasion, metastasis and inflammation associated with tumors. They may also play a role in the inability of immune checkpoint inhibitors to affect more resistant tumors. WP1220 is a close analog to WP1066 that the Company has developed as a potential topical therapy for skin-related diseases.
WP1220 is currently being evaluated for the treatment of Cutaneous T-Cell Lymphoma (CTCL) and WP1066 is currently being evaluated for the treatment of pediatric brain tumors, including Diffuse Interstitial Pontine Glioma (DIPG). Additionally, WP1066 + radiation is being evaluated in the treatment of treatment of Glioblastoma Multiforme (GBM).
WP1122 is a prodrug of 2-DG that appears to improve the drug-like properties of 2-DG by increasing its circulation time and improving tissue/organ distribution. Recent published research has identified that 2-DG has antiviral potential against SARS-CoV-2 in vitro and, based on publicly available information, a recently completed Phase 2 clinical trial by an unrelated company in India has reported efficacy in COVID-19 patients, resulting in the Emergency Use Authorization of 2-DG by the Drugs Controller General of India. New research also points to the potential for 2-DG to be capable of enhancing the usefulness of checkpoint inhibitors. Considering that WP1122 generally outperforms 2-DG alone in both in vitro and in vivo tumor models and in viral in vitro models, we believe WP1122 has the potential to become an important drug to potentiate existing therapies, including checkpoint inhibitors.
