Can-Fite Reports Second Quarter 2017 Financial Results & Provides Clinical Update

On September 1, 2017 Can-Fite BioPharma Ltd. (NYSE American: CANF) (TASE:CFBI), a biotechnology company with a pipeline of proprietary small molecule drugs that address inflammatory and cancer diseases, reported financial results for the six months ended June 30, 2017 and provided clinical and corporate updates (Press release, Can-Fite BioPharma, SEP 1, 2017, View Source [SID1234520359]).

Clinical Development Program and Corporate Highlights Include:

Namodenoson (CF102): Progress in Clinical Development and Receipt of Milestone Payment

● Patient Enrollment Completed in Phase II Liver Cancer Trial of Namodenoson

Can-Fite enrolled and randomized all 78 patients for its global Phase II study of Namodenoson in the treatment of hepatocellular carcinoma (HCC), the most common form of liver cancer. Patients with advanced HCC, Child Pugh B, were enrolled in the U.S., Europe and Israel. The primary endpoint of the Phase II study is overall survival. Can-Fite is following the survival data closely and plans to perform the survival analysis at the earliest possible opportunity. The HCC market is expected to generate $1.4 billion in sales in 2019.

● Milestone Payment Received for Distribution of Namodenoson in Korea for the Treatment of Liver Cancer

In August 2017, Can-Fite received a milestone payment of $500,000 from Chong Kun Dang Pharmaceuticals (CKD), which licensed the exclusive right to distribute Namodenoson for the treatment of liver cancer in Korea upon receipt of regulatory approvals. The payment is part of a deal worth up to $3,000,000 in upfront and milestone payments plus 23% royalties.

● Namodenoson to Commence Phase II Trial in the Treatment of NAFLD/NASH

During the second quarter of 2017, Can-Fite conducted a successful Clinical Investigator Meeting with principal investigators, researchers, and doctors participating as clinical investigators in the Company’s Phase II trial of Namodenoson in the treatment of non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). Namodenoson drug supply for the trial has been paid for and is ready to be administered to patients. The trial protocol has been approved by two leading Institutional Review Boards in Israel. Can-Fite estimates the cost of this Phase II trial to be less than $1 million. Patient enrollment is expected to begin in the third quarter of 2017. By 2025, the addressable pharmaceutical market for NASH is estimated to reach $35-40 billion.

● Established Clinical Advisory Board for NASH Indication

Can-Fite established a Clinical Advisory Board comprised of Key Opinion Leaders to provide advice and steer Namodenoson’s clinical development program in the treatment of NAFLD and NASH. Board members include researchers and medical practitioners in the field of liver disease from institutions including Mount Sinai in New York, Virginia Commonwealth University School of Medicine, and Hadassah University in Israel.

Piclidenoson (CF101): ACRobat Phase III Trial in Rheumatoid Arthritis to Commence

In August 2017, Can-Fite successfully concluded a cardiodynamic trial for its lead drug candidate Piclidenoson, which showed favorable safety data required by the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) prior to initiation of Phase III studies.

During the second quarter of 2017, Can-Fite conducted a successful Clinical Investigator Meeting with approximately 100 rheumatologists, and their staff, who are participating as clinical investigators in the Company’s global pivotal Phase III ACRobat study, which is set to commence patient enrollment in the third quarter of 2017.

ACRobat is a Phase III trial that will evaluate Piclidenoson as a first line treatment and replacement for the current standard of care, Methotrexate (MTX), the most widely used drug for rheumatoid arthritis. The trial will enroll approximately 500 patients in Europe, Canada and Israel. The estimated cost of the entire Phase III study is approximately $5 million. Rheumatoid arthritis is a treatment market forecast to reach $34.6 billion by 2020.

Piclidenoson is also being developed as a treatment for psoriasis. Can-Fite is preparing for an upcoming Phase III trial that will investigate the efficacy and safety of Piclidenoson compared to placebo as its primary endpoint and as compared to apremilast (Otezla) as its secondary endpoint in approximately 400 patients with moderate-to-severe plaque psoriasis. Can-Fite expects to submit its clinical protocol to Institutional Review Boards in the fourth quarter of 2017. The psoriasis market is forecast to be $8.9 billion in 2018 and Otezla sales are estimated to be $2.35 billion by 2020.

“Completion of patient enrollment in our Phase II study is a significant advancement in the development of Namodenoson to treat liver cancer. We will evaluate results as soon as possible based on survival data. There is a clear unmet medical need for HCC patients with Child-Pugh Class B cirrhosis. Our Orphan Drug status in both the U.S. and Europe, as well as Fast Track status in the U.S. in this indication, we believe will accelerate our path towards applying for market approval for Namodenoson for liver cancer,” stated Can-Fite CEO Dr. Pnina Fishman. “In the current quarter, we look forward to commencing patient enrollment in our Phase II NAFLD/NASH study for Namodenoson and our Phase III rheumatoid arthritis study for Piclidenoson.”

Financial Results

Revenues for the six months ended June 30, 2017 were NIS 0.53 million (U.S. $0.15 million) compared to NIS 0.43 million (U.S. $0.12 million) in the first six months of 2016. The increase in revenue was mainly due to the recognition of a portion of the NIS 1.9 million (U.S. $0.5 million) advance payment received in December 2016 under the distribution agreement with CKD.

Research and development expenses for the six months ended June 30, 2017 were NIS 8.84 million (U.S. $2.53 million) compared with NIS 9.97 million (U.S. $2.85 million) for the same period in 2016. Research and development expenses for the first half of 2017 comprised primarily of expenses associated with the Phase II study for Namodenoson, the preclinical study of CF602, as well as expenses for ongoing studies of Piclidenoson. The decrease is primarily due to a reduction in preclinical studies of CF602 conducted during the six months ended June 30, 2017.

General and administrative expenses were NIS 5.0 million (U.S. $1.43 million) for the six months ended June 30, 2017, the same as the general and administrative expenses for the same period in 2016.

Financial income, net for the six months ended June 30, 2017 aggregated NIS 1.57 million (U.S. $0.45 million) compared to financial income, net of NIS 3.19 million (U.S. $0.91 million) for the same period in 2016. The decrease in financial income, net in the first half of 2017 was mainly from exchange rate differences as compared to the same period in 2016 and from issuance expenses, offset by a larger decrease in the fair value of warrants that are accounted for as financial liability as compared to the same period in 2016.

Can-Fite’s net loss for the six months ended June 30, 2017 was NIS 11.72 million (U.S. $3.35 million) compared with a net loss of NIS 11.35 million (U.S. $3.25 million) for the same period in 2016. The slight increase in net loss for the first half of 2017 was primarily attributable to a decrease in financial income, net.

As of June 30, 2017, Can-Fite had cash and cash equivalents of NIS 23.98 million (U.S. $6.86 million) as compared to NIS 31.2 million (U.S. $8.92 million) at December 31, 2016. The decrease in cash during the six months ended June 30, 2017 is due to use of cash to fund operating expenses.

For the convenience of the reader, the reported NIS amounts have been translated into U.S. dollars, at the representative rate of exchange on June 30, 2017 (U.S. $1 = NIS 3.496).

The Company’s consolidated financial results for the six months ended June 30, 2017 are presented in accordance with International Financial Reporting Standards.

MacroGenics Announces Termination of Duvortuxizumab Collaboration and License Agreement with Janssen

On August 31, 2017 MacroGenics, Inc. (NASDAQ: MGNX), a clinical-stage biopharmaceutical company focused on discovering and developing innovative monoclonal antibody-based therapeutics for the treatment of cancer, as well as autoimmune disorders and infectious diseases, reported that it had been notified by its partner, Janssen Biotech, Inc., that Janssen is terminating the collaboration and license agreement with MacroGenics relating to duvortuxizumab, a CD19 x CD3 DART molecule (Press release, MacroGenics, AUG 31, 2017, View Source [SID1234520350]). Enrollment of the Phase 1 dose-escalation study of this molecule is being discontinued.

Janssen reaffirmed its commitment to MGD015, also known as JNJ-9383, a second DART molecule licensed from MacroGenics. MGD015 is a preclinical program that targets CD3 and a non-disclosed cancer antigen expressed in hematological malignancies and lung cancer. Janssen has indicated that it anticipates initiating a first-in-human study with this molecule in 2018.

In the Phase 1 dose-escalation study of duvortuxizumab, multiple objective responses were observed in patients treated at various dosing levels tested. However, a number of patients experienced treatment-related neurotoxicity similar to that seen in patients treated with other CD19-targeted T-cell therapies. Given the recent advances in the highly competitive field for the treatment of B cell malignancies, the opportunity for development and commercialization has become less attractive.

"While this decision is disappointing, MacroGenics and its strategic partner, Janssen, continue to be fully committed to the DART platform and our ongoing collaboration on MGD015. Duvortuxizumab’s neurotoxicity profile is a CD19-targeting issue and has not been observed in our other DART clinical programs," said Scott Koenig, M.D., Ph.D., President and Chief Executive Officer of MacroGenics. "Given our large portfolio of product candidates currently being pursued, it is unlikely that we will continue development of this molecule at this time."

BeiGene Announces Closing of Global Strategic Oncology Collaboration with Celgene Corporation

On August 31, 2017 BeiGene, Ltd. (NASDAQ:BGNE), a clinical-stage biopharmaceutical company developing innovative molecularly targeted and immuno-oncology drugs for the treatment of cancer, reported the closing of its global strategic oncology collaboration with Celgene Corporation (Press release, BeiGene, AUG 31, 2017, View Source [SID1234520354]).

The collaboration was announced on July 5, 2017. Under the terms of the agreements, BeiGene has acquired Celgene’s commercial operations in China and assumed commercial responsibility for Celgene’s approved therapies in China (Abraxane, Revlimid, and Vidaza) and pipeline agent CC-122. Celgene has received exclusive rights to develop and commercialize BeiGene’s investigational anti-PD1 antibody, BGB-A317, for solid tumors in the United States, Europe, Japan, and the rest of the world outside of Asia. BeiGene retains rights to BGB-A317 for solid tumors in Asia (excluding Japan), and for hematological malignancies and internal BeiGene combinations globally. BeiGene will receive an aggregate of $413 million from Celgene in upfront licensing fees and equity investment, and will be eligible for up to an additional $980 million in development, regulatory, and sales milestones, as well as royalties on future sales of BGB-A317.

About BGB-A317

BGB-A317 is an investigational humanized monoclonal antibody that belongs to a class of immuno-oncology agents known as immune checkpoint inhibitors. It is designed to bind to PD-1, a cell surface receptor that plays an important role in downregulating the immune system by preventing the activation of T-cells. BGB-A317 has high affinity and specificity for PD-1. It is differentiated from the currently approved PD-1 antibodies in an engineered Fc region, which is believed to minimize potentially negative interactions with other immune cells. BGB-A317 is being developed as a monotherapy and in combination with other therapies for the treatment of a broad array of both solid tumor and hematologic cancers. BeiGene and Celgene have a global strategic collaboration for BGB-A317 for solid tumors.

Aptevo Therapeutics and MorphoSys End Joint Development and Commercialization Agreement for MOR209/ES414

On August 31, 2017 Aptevo Therapeutics Inc. (Nasdaq:APVO), a biotechnology company focused on developing novel immuno-oncology and hematology therapeutics, reported the end of its partnership with MorphoSys AG for the joint worldwide development and commercialization of MOR209/ES414, a targeted immunotherapeutic for the treatment of metastatic castration resistant prostate cancer (mCRPC) (Press release, Aptevo Therapeutics, AUG 31, 2017, View Source [SID1234520353]). Aptevo will regain worldwide development and commercialization rights for MOR209/ES414 (now known as APVO414) and intends to continue to advance APVO414 through the completion of Stage 1 of an ongoing Phase 1 continuous infusion, dose-escalation clinical study evaluating the safety, tolerability and clinical activity of escalating doses of APVO414 in patients with mCRPC.

"We’re encouraged by the latest preliminary data from the ongoing Phase 1 clinical study of APVO414," said Dr. Scott Stromatt, Senior Vice President and Chief Medical Officer at Aptevo. "The data suggest that administration of APVO414 by continuous infusion, rather than weekly intravenous (IV) dosing, is effective at reducing the titer of anti-drug antibodies (ADA) previously observed in the initial weekly IV dosing cohorts."

In the initial cohorts of the Phase 1 dose escalation study, twelve patients with mCRPC were treated with weekly intravenous infusions of APVO414. Seven of these patients (58%) developed ADA with very high titers (as high as 1:250,000). None of the patients had any adverse reactions due to the ADA, but patients with high ADA titers cleared the drug from their blood to undetectable levels.

The amended protocol utilizes continuous intravenous infusion and two cohorts of patients have completed dosing without any dose limiting toxicities. Three of six patients (50%) developed ADA but with markedly lower titers of ADA (1:160 or 1:320). Additionally, drug was detected in the serum of all patients.

"These results clearly demonstrate that the administration regimen markedly reduced the generation of ADA. Additionally, we have seen early pharmacodynamic effects of the drug such as redistribution of T cells. We are encouraged and plan to continue dose escalation in order to determine the maximum tolerated dose and to examine the clinical activity of APVO414," said Dr. Stromatt.

APVO414 is a first-generation bispecific antibody candidate, developed using Aptevo’s ADAPTIR protein therapeutic platform. APVO414 is engineered to simultaneously target PSMA on prostate cancer cells, and CD3 on T-cells, and functions by redirecting cytotoxic T cell activity towards PSMA-expressing tumor cells.

Promising preclinical data demonstrating the ability of APVO414 to induce target-dependent tumor cell killing as well as target-dependent T cell proliferation were previously presented at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting and recently published in the Journal of Molecular and Cellular Biology (2016 Mol Cancer Ther; 15(9); 2155–65). In addition, APVO414 demonstrated lower levels of T cell dependent cytokines compared to other bispecific formats, which, if confirmed in clinical studies, could offer the potential for enhanced safety and tolerability compared to other immuno-oncology bispecific antibody approaches.

"Aptevo has made a number of significant improvements to our ADAPTIR platform since the development of our first-generation bispecific candidates, like APVO414," commented Jane Gross, Ph.D., Senior Vice President and Chief Scientific Officer. "Our next generation ADAPTIR technology platform has been optimized to enable the development of bispecific antibody candidates with highly-desirable drug-like properties, including, enhanced potency and stability, prolonged half-life, and excellent manufacturing attributes – similar to traditional antibodies. Importantly, we have utilized state-of-the-art technologies to examine our next generation bispecific candidates and believe that we identified and eliminated the root cause of the ADA seen with APVO414. We look forward to obtaining additional information from the ongoing APVO414 clinical trial and advancing next generation ADAPTIR bispecific molecules into clinical development."

About Prostate Cancer

Although screening, radiation, surgery and hormone ablation therapy have greatly improved the detection and treatment of early-stage prostate cancer, the relapse rate following initial anti-androgen therapy remains high, and there remains a significant unmet medical need for patients with metastatic castration resistant prostate cancer for whom current therapies have demonstrated only a limited increase in overall survival. The global market for CRPC therapeutics is expected to reach $9.5 billion by 2020

About the ADAPTIR Pipeline

Two first generation ADAPTIR molecules are currently in clinical development: APVO414, which is being investigated in a Phase 1, dose escalation, continuous infusion study to evaluate safety and tolerability in patients with metastatic castration resistant prostate cancer; and, otlertuzumab, a monospecific antibody targeting CD37 under investigation for the treatment of chronic lymphocytic leukemia. In addition, Aptevo has several ADAPTIR candidates in preclinical development, including: APVO436, an optimized, next generation bispecific antibody candidate designed to simultaneously target CD123 and CD3 and redirect T cell cytotoxicity for the treatment of acute myelogenous leukemia (AML), a form of blood and bone marrow cancer; ALG.APV-526, a bispecific antibody candidate, partnered with Alligator Bioscience, featuring a novel mechanism of action designed to simultaneously target 4-1BB (CD137) and an undisclosed tumor antigen, and, APVO210 – a bispecific ADAPTIR candidate with a novel mechanism of action based on cytokine delivery currently in preclinical development for autoimmune and inflammatory diseases.
