About the Company’s Neuroprotection Program
Our lead drug candidate, PTI-125, is a small molecule with a unique mechanism of action for treating Alzheimer’s disease ("AD"). We expect to initiate a Phase IIa study with PTI-125 in AD in Q4 2018.

The underlying science for PTI-125 is published in prestigious peer-reviewed journals, including Journal of Neuroscience, Neurobiology of Aging, and Neuroimmunology and Neuroinflammation, and benefits from several peer-reviewed research grant awards from the NIH.

We are also developing a blood-based test, called PTI-125Dx, to detect whether a person has Alzheimer’s disease, possibly years before any symptoms appear. An early diagnosis of AD could optimize treatment options and empower physicians and patients to slow or halt the disease.

About Alzheimer’s Disease
Alzheimer’s Disease (AD) is a progressive brain disorder that destroys memory and thinking skills. Eventually, a person with AD may be unable to carry out even the simplest tasks. There is a profound and timely need to develop new drugs for Alzheimer’s. Currently, there are no drug therapies to halt Alzheimer’s, much less reverse its course.

On October 23, 2018 Novocure (NASDAQ: NVCR) reported that results from a post-hoc analysis of Novocure’s EF-14 phase 3 pivotal trial in newly diagnosed glioblastoma (GBM) that demonstrated that a higher dose of Tumor Treating Fields delivered to the tumor bed was associated with improved overall survival (Press release, NovoCure, OCT 23, 2018, View Source [SID1234530074]). For Tumor Treating Fields, the term delivered dose is a function of power loss density, a measure of energy, and compliance, or monthly usage of therapy. Tumor Treating Fields is a cancer therapy that uses electric fields tuned to specific frequencies to disrupt cell division, inhibiting tumor growth and causing affected cancer cells to die. The analysis was presented today at the American Society for Radiation Oncology (ASTRO) 2018 Annual Meeting in San Antonio, Texas.

"This post-hoc analysis of EF-14 is extremely valuable to the radiation oncology community and supports the importance of targeting the tumor of each patient when planning treatment with Tumor Treating Fields," said Matt Ballo, MD, FACR, Director of Radiation Oncology at West Cancer Center in Germantown, Tennessee. "I believe an increased understanding of delivered dose will allow our treatment planning to become more sophisticated over time and help us achieve better patient outcomes."

The post-hoc analysis used patient data from the Tumor Treating Fields treatment arm of Novocure’s EF-14 phase 3 pivotal trial and included only patients who were treated for more than two months to ensure sufficient treatment duration to reach tumor stabilization and for whom quality MRI data was available. Of the 466 patients in the Tumor Treating Fields treatment arm, 379 received therapy for more than two months, and 317 of these patients had sufficient MRI quality to build head models. For each of these 317 patients, an individualized electric field distribution model within the head was created. Transducer arrays were placed on each model and simulations were run to calculate both electric field intensity and power loss density within the tumor bed. Electric field intensity measures the force acting on charges within a region of treatment and power loss density measures the amount of energy at the tumor bed. Power loss density at the tumor bed is a factor of both electric field intensity and tissue conductivity within the region of treatment.

Higher electric field intensity (≥1.0 Volts/cm) and higher power loss density (≥1.1 mW/cm3) at the tumor bed were both associated with improved overall survivals, independent of compliance, or monthly usage of therapy. Power loss density was the most significant driver with a median overall survival of 25.23 months for patients treated with Tumor Treating Fields at power loss densities greater than or equal to 1.1 mW/cm3 (n=122), compared to a median overall survival of 21 months (n=195) for patients treated with Tumor Treating Fields at power loss densities less than 1.1 mW/cm3 (HR, 0.59; 95 percent Cl, 0.43-0.81; P<.01).

A previously presented analysis of EF-14 data demonstrated that more time on Optune predicted an increased survival benefit in patients with newly diagnosed GBM. In the analysis presented today, the greatest improvement in median overall survival among all sub groups was seen in patients who both spent more time on Optune and received Tumor Treating Fields at higher power loss densities. Patients who used Optune more than 85 percent (n=36) of the time and received Tumor Treating Fields at power loss densities greater than or equal to 1.1 mW/cm3 had the greatest improvements in overall survival. Tumor Treating Fields delivered dose can now be defined as a factor of both power loss density and monthly usage of therapy.

"This analysis demonstrated a dose dependence on the overall survival of GBM patients treated with Tumor treating Fields and that improvements in overall survival were possible when patients received an increased delivered dose of Tumor Treating Fields," said Dr. Eilon Kirson, Novocure’s Chief Science Officer and Head of Research and Development. "The NovoTAL System is available to help physicians optimize and individualize treatment planning for patients by directing electric field intensity to the region of active tumor. We are committed to further developing our technology and believe increasing the power loss density of Tumor Treating Fields at the tumor bed through treatment planning has the potential to improve patient outcomes."

On October 23, 2018 Ophthotech Corporation (Nasdaq:OPHT) reported that it will report its third quarter 2018 financial and operating results on Wednesday, October 31, 2018 (Press release, Ophthotech, OCT 23, 2018, View Source [SID1234530059]).

On October 23, 2018 CStone Pharmaceuticals ("CStone") reported that the United States Food and Drug Administration (FDA) has recently granted approval to the company’s Investigational New Drug (IND) application for the independently developed recombinant humanized anti-programmed death-1 (PD-1) monoclonal antibody (mAb) CS1003 (Press release, CStone Pharmaceauticals, OCT 23, 2018, View Source [SID1234530075]). This represents CStone’s second drug candidate to receive IND approval from the FDA less than one month after US clinical trial approval for CS1001 (PD-L1), and demonstrates CStone’s global clinical development capability.

"Since May this year, CS1003 has now quickly received clinical trial approvals in Australia, China, and the United States, indicating that there are high expectations behind the product itself," said Dr. Frank Jiang, Chairman and CEO of CStone. "I hope that in the future CS1003 can play a key role within combination cancer drug therapies."

CS1003 is a full-length, humanized immunoglobulin G4 (IgG4) anti-PD-1 monoclonal antibody that has shown a good tolerability and efficacy profile in preclinical in vivo studies. The forthcoming clinical trial in the United States extends the Phase I study that began in Australia in May this year to US research centers, and will determine the recommended Phase II dose (RP2D) for CS1003 in solid tumor patients.

Dr. Jason Yang, CStone’s Chief Medical Officer commented: "PD-1 and PD-L1 immunotherapy have been shown to produce strong therapeutic effects in various cancers both as single agents or in combination with multiple cancer therapeutics. CS1003 is a key pipeline candidate for CStone and is currently progressing smoothly through Phase I trial in Australia. We will continue to push forward CS1003’s development in China and around the world to provide patients with a new treatment option at the earliest opportunity."

About CS1003 and the PD-1/PD-L1 pathway

PD-1, or programmed death-1, is an inhibitory checkpoint receptor expressed on T cells. Under normal circumstances, it binds with its ligands, programmed death ligand-1 or ligand 2 (PD-L1/PD-L2), inhibiting T cell and cytokine activation, serving to dampen the immune response in order to prevent damage to healthy tissues. However, studies have shown that PD-L1 can be abundantly expressed on the surface of many solid tumors as well as hematological malignancies. Cancer cells can therefore make use of the PD-1/PD-L1 pathway to successfully avoid immune system recognition. Targeting of the PD-1/PD-L1 checkpoint by anti-tumor drugs can block the "tumor immune evasion mechanism" and restore anti-cancer immune ability in patients.

Unlike other anti-PD-1 mAbs, CS1003 recognizes both human and murine PD-1, providing a unique competitive advantage during efficacy testing in syngeneic mouse tumor models particularly for development of effective combination therapies.
