On December 21, 2016 Exosome Diagnostics, Inc. reported data that sets a new standard for EGFR-T790M resistance mutation detection in lung cancer, with the highest sensitivity reported to date (Press release, Exosome Diagnostics, DEC 21, 2016, View Source [SID1234517160]). This test is being developed to improve care and outcomes for the large population of patients who can benefit from second line EGFR Tyrosine Kinase Inhibitor (TKI) therapy but are missed with currently available tissue and liquid biopsy tests. Clinical validation data from a cohort of 160 patients, the largest of its kind in this patient population, was presented in plenary session during the recent AACR (Free AACR Whitepaper)-EORTC-NCI meeting in Munich, Germany. ExoDx Lung(T790M) has been optimally designed for ExosomeDx’s high throughput biomarker testing platform that is being deployed in 2017.

Twenty percent of non-small cell lung cancer (NSCLC) patients test positive for an EGFR driver mutation (approximately 45,000 patients in the U.S. alone) and receive EGFR TKI therapy. Unfortunately, most will develop a resistance to EGFR TKI therapy. Tissue biopsies are the current standard for identifying T790M resistance. If a patient tests positive, they are eligible for treatment with a second line EGFR TKI therapy. Unfortunately, a tissue biopsy is not always a viable option for a large percentage of these patients.

Non-invasive liquid biopsies have emerged as a viable alternative for patients unable to have tissue biopsy procedure. Clinical studies have demonstrated that the FDA approved cobas test for liquid biopsy, only identifies 59% of patients who will respond to a second line EGFR TKI therapy. This is a direct result of lack of sensitivity and inability to test challenging intrathoracic disease. By analyzing exosomal RNA (exoRNA) and cell free tumor DNA (ctDNA) from the same sample Exosome Dx addresses current limitations by identifying 96% of the T790M positive population, with no loss of sensitivity in patients with intrathoracic disease.

"EGFR T790M mutations have previously been challenging for liquid biopsy assays. In this clinical study, we show that ExoDx Lung(T790M) has a higher clinical sensitivity and specificity than what has been reported to date for the FDA cleared test distributed by Roche. This study further demonstrates the power of our ExoLution Plus platform that combines exoRNA plus ctDNA. This result was not surprising since we have shown superior performance to ctDNA across several disease states in blinded head to head studies. Clinical samples are precious so we are thrilled to be able to offer a more sensitive test that take both exoRNA and ctDNA into consideration,"stated Dr. Johan Skog, Chief Scientific Officer at Exosome Diagnostics.
The test is the latest in a series of biofluids based diagnostic and companion diagnostic biomarker tests being developed by Exosome Diagnostics to potentially aid in therapy selection and patient monitoring in oncology and other diseases.

To assure future access to the company’s novel biomarker tests worldwide, Exosome Diagnostics also announced that it has developed a high throughput version of its proprietary ExoLution Plus system to prepare samples that can be analyzed with exoRNA and cfDNA analysis test kits. This system utilizes Exosome Diagnostics’ patented technology and has been developed with high throughput capability to be integrated with leading clinical laboratory analytical systems including those marketed by Roche and Thermo Fisher

"This data illustrates one of the many indications for which Exosome Diagnostics can leverage its extremely sensitive liquid biopsy technology to improve patients’ lives by guiding therapy, where other technologies could not in a reliable fashion" stated John Boyce, President and CEO of Exosome Diagnostics. "Exosome Diagnostics has proven that its technology is extremely robust and can scale on a variety of existing commercial platforms in diagnostic laboratories," Boyce continued.

"We are delighted with the participation of such high caliber investors in our first equity round," said David J. Earp, J.D., Ph.D., Circle’s president and CEO. "With our seed funding, we established Circle’s computational design platform, advanced our synthetic chemistry capabilities in collaboration with ChemPartner, and engaged in a target-based collaboration with Pfizer. The Series A funds will be used to support Circle’s therapeutic pipeline, which is focused on intracellular protein-protein interactions that are key drivers in oncogenic pathways. We are also now building a physical library of cell- permeable macrocycles to augment our computational design tools, and this library will later be available to our collaboration partners. We are particularly excited to welcome Walter Moos to our Board of Directors. Dr. Moos brings a wealth of life sciences R&D experience, having served most recently as the president of SRI Biosciences and previously in senior executive roles at MitoKor, Chiron and Warner-Lambert/Parke-Davis. His teams have advanced numerous pharmaceutical products from discovery to commercialization, and we are fortunate to have him join Circle."

"I am very much looking forward to taking an active role on Circle’s board," said Walter Moos. "The combination of innovative technology and the great team at Circle could help unlock high value targets that have long been considered out of reach of drug developers."

Dr. Moos has served on about 20 business and scientific boards, including Amunix, Oncologic (Aduro), Onyx (Amgen), Rigel and the Biotechnology Industry Organization (BIO).

About Macrocyclic Peptides

Macrocyclic peptides have the potential to allow drug developers to address the large proportion of known therapeutic targets (estimated at up to 80%) that are considered undruggable with conventional small molecule or biologic modalities. In particular, there is great interest in developing macrocycles to modulate protein-protein interactions, which play a role in almost all disease conditions, including cancer, fibrosis, inflammation and infection. However, the development of macrocyclic therapeutics has been limited by the need for a greater understanding of how to develop macrocycles with appropriate pharmacokinetics, cell permeability and oral bioavailability. Circle’s ability to design potent macrocycles with intrinsic cell permeability could unlock access to challenging, high value therapeutic targets that have been out of reach to other approaches.

On December 21, 2016 Merrimack Pharmaceuticals, Inc. (Nasdaq: MACK) reported that, following a recent independent Data and Safety Monitoring Board (DSMB) recommendation and subsequent futility analysis, it has decided to stop the Phase 2 HERMIONE study of MM-302 (HER2 antibody-targeted liposomal doxorubicin) in HER2-positive metastatic breast cancer patients who had previously been treated with trastuzumab (Herceptin), pertuzumab (Perjeta) and ado-trastuzumab emtansine (T-DM1, Kadcyla) (Press release, Merrimack, DEC 21, 2016, View Source [SID1234517147]).

The decision to stop the trial was made following the DSMB’s opinion that continuing would be unlikely to demonstrate benefit over the comparator treatments. Subsequent to this recommendation, a futility assessment was performed that confirmed the DSMB’s opinion. Both the treatment and control arms were found to have shorter than expected median progression free survival.

Importantly, there were no new or unexpected safety concerns. Patients currently enrolled in the trial may choose to continue on their assigned treatment based upon discussion with their study physician.

"Late line HER2-positive breast cancer is very difficult to treat, especially in this new and previously unstudied group of patients who appear to experience rapid cancer progression following treatment with trastuzumab, pertuzumab and ado-trastuzumab emtansine," said Istvan Molnar, MD, Vice President of Clinical Development at Merrimack Pharmaceuticals. "While we are disappointed with this outcome, we would like to thank the study Steering Committee, the investigators and, most importantly, the patients who participated in the HERMIONE trial. We will report our learnings from this study at a later date."

In light of this development, Merrimack now expects to provide further details about MM-302, as well as the results of its full pipeline review, in January.

On December 21, 2016 Can-Fite BioPharma Ltd.

"We are pleased to receive this upfront payment of $500,000 from CKD and look towards future potential milestone payments as we advance Namodenoson through completion of our current Phase II trial as a second line treatment for hepatocellular carcinoma and into Phase III," stated Can-Fite CEO Dr. Pnina Fishman.

Per the terms of the distribution agreement, Can-Fite will deliver finished product to CKD and CKD has a right of first refusal to distribute Namodenoson for other indications for which Can-Fite develops Namodenoson.

Can-Fite is currently conducting a global Phase II double-blind, placebo controlled study evaluating the efficacy of Namodenoson as a second-line treatment for advanced HCC. The primary endpoint is overall survival. In the coming quarters, Can-Fite intends to initiate a Phase II study of Namodenoson in the treatment of non-alcoholic fatty liver disease (NAFLD), the precursor to non-alcoholic steatohepatitis (NASH).

About Namodenoson (CF102)

Namodenoson is a small orally bioavailable drug that binds with high affinity and selectivity to the A3 adenosine receptor (A3AR). A3AR is highly expressed in diseased cells whereas low expression is found in normal cells. This differential effect accounts for the excellent safety profile of the drug. In Can-Fite’s pre-clinical and clinical studies, Namodenoson has demonstrated a robust anti-tumor effect via deregulation of the Wnt signaling pathway, resulting in apoptosis of liver cancer cells. Based on preclinical data showing Namodenoson has strong liver protective properties, Can-Fite intends to initiate a Phase II study in NASH. Can-Fite has received Orphan Drug Designation for Namodenoson in Europe and the U.S., as well as Fast Track Status in the U.S. as a second line treatment for hepatocellular carcinoma.
