CureVac and Arcturus Therapeutics Announce Broad Strategic Collaboration to Advance Next Generation of Lipid-Mediated mRNA Therapeutics

On January 4, 2018 CureVac AG, a leading clinical-stage biopharmaceutical company focused on the development of pioneering mRNA therapeutics, and Arcturus Therapeutics Ltd. (NASDAQ:ARCT), an RNA medicines company, reported they have entered into a broad strategic collaboration to jointly discover, develop and commercialize novel messenger RNA (mRNA) therapeutics (Press release, CureVac, JAN 4, 2018, View Source [SID1234522914]).

Under the agreement, the companies will collaborate to develop up to four molecular therapy products for rare diseases using Curevac’s optimized natural mRNA sequence (RNAoptimizer) and Arcturus’s lipid-mediated nucleic acid delivery system (LUNAR). The agreement focuses on developing mRNA therapeutics for enzyme replacement and antibody generation. Development costs will be shared between the companies, with plans to co-commercialize products in the future under a profit sharing arrangement. The first mRNA therapy to be jointly developed and potentially commercialized by the companies will target ornithine transcarbamylase (OTC) deficiency, a genetic disease characterized by the accumulation of ammonia in the blood. The collaboration also grants CureVac access to the full suite of Arcturus’s lipid-mediated delivery intellectual property to enable the development of additional mRNA product candidates.

"This collaboration for up to four products establishes a sound relationship with Arcturus, which we believe is one of the leaders in developing lipid-mediated delivery systems for mRNA molecules," said Ingmar Hoerr, Ph.D., co-founder and CEO of CureVac. "Just as important, we are excited to have secured access to Arcturus’s leading intellectual property rights for future product development in molecular therapies. This partnership combines both companies’ technology platforms with the expertise necessary to develop the next generation of therapeutics based on the considerable potential of mRNA."

"We are thrilled to combine Arcturus’s platform technologies and expertise with CureVac’s recognized capabilities in mRNA construct optimization and GMP manufacturing to co-develop messenger RNA medicines for patients in need," said Joseph Payne, President and CEO of Arcturus. "We believe our collaboration with CureVac has the potential to help reduce costs, mitigate manufacturing risks, and accelerate our timelines for ushering quality mRNA medicines into the clinic."

"The support for this transaction by both Inotek and Rocket shareholders was evident today, underscoring support for our long-term growth strategy to become a fully-integrated, multi-platform gene therapy company," said Dr. Shah. "The closing of this merger provides immediate value to grow our operations, execute on our clinical development goals, and expand our in-house manufacturing and analytics capabilities. As we enter this next stage of growth as a publicly traded company, we are focused on driving Company value by bringing our current pipeline of five programs to major value inflection points as rapidly as possible, and achieving first mover advantage in these markets."

Rocket’s Pipeline

Rocket utilizes a multi-platform development approach that leverages the well-established lentiviral vector (LVV) and adeno-associated viral vector (AAV) gene delivery methods and is initially targeting devastating rare diseases in children that lead to early mortality in the absence of bone marrow transplant or other invasive procedures.

The Company’s lead program, a Phase 1/2 LVV-based gene therapy for Fanconi Anemia (FA), is currently in clinical trials with academic partners in the U.S. and Europe. FA causes genetic instability due to mutations in DNA repair genes resulting in early bone marrow failure and malignancy. Early results in FA patients have demonstrated clinical engraftment of ex vivo-transduced autologous hematopoietic stem cells (HSCs). The proportion of gene-corrected cells increases over time, confirming the selective advantage of gene-corrected cells in the bone marrow without requiring conditioning (i.e. destruction of bone marrow prior to transplant). Functional correction and clinical proof of concept have also been observed. Both blood and marrow cells demonstrate resistance to DNA-damaging agents (sensitivity to DNA-damaging agents is a diagnostic feature of FA). Patients demonstrated stable or improving blood cell counts during the months following treatment despite decreases noted during the months and years preceding gene therapy. Additional patient data are expected in 2018, with a registration study anticipated to start in 2019.

Three additional LVV-based programs are currently in preclinical development and target Leukocyte Adhesion Deficiency-I (LAD-I), Pyruvate Kinase Deficiency (PKD) and Infantile Malignant Osteopetrosis (IMO). The LAD-I program is expected to advance into the clinic in 2018, with the PKD and IMO programs to follow in 2019.

An undisclosed AAV-based gene therapy program is expected to enter the clinic in the next year and has demonstrated encouraging histological correction of the disease phenotype. This program targets a monogenic pediatric disease with early mortality and represents the first gene therapy being developed for this large class of indications.

Rocket’s Management

The combined Company’s executive management team will be led by Dr. Shah and will consist of: Jonathan Schwartz, M.D., Chief Medical Officer, who led several biologics approvals as Vice President of Clinical Development at ImClone Systems/Eli Lilly and Company; Kinnari Patel, Pharm.D., MBA, newly appointed Chief Operating Officer, who led regulatory filings for six rare disease agents as well as for Opdivo while at Bristol-Myers Squibb; and Brian Batchelder, MBA, Vice President of Finance, who previously served as Chief Financial Officer of ImClone Systems, a subsidiary of Eli Lilly and Company.

In addition, Rocket appointed Claudine Prowse, Ph.D., as Head of Corporate Development and Investor Relations Officer. Previously, she was Head of Strategy at Inotek, where she was integral to the merger transaction with Rocket Pharmaceuticals, Ltd. Prior to that, she was Vice President of Investor Relations at Biogen.

About the Merger

Prior to the closing of the merger, Inotek effected a 1 for 4 reverse split of its common stock. Following the reverse stock split and closing of the merger, there will be approximately 33.1 million shares of the combined company’s common stock outstanding with prior Rocket shareholders owning approximately 79.4% and prior Inotek shareholders owning approximately 20.6%. Based on the reverse stock split, the conversion rate of the combined Company’s $52.0 million of 5.75% Convertible Senior Notes due 2021 will automatically be adjusted from 124.7505 shares of common stock per $1,000 principal amount of the notes to 31.1876 shares of common stock per $1,000 principal amount of the notes. Cash, cash equivalents and short-term investments for the combined Company at closing were approximately $117.2 million.

SignalRx Announces In Silico Design And Discovery Of The First-In-Class HDAC6-BRD4-PI3K Epigenetic Kinase Inhibitor SRX3225

On January 4, 2018 SignalRx Pharmaceuticals Inc., a clinical-stage company developing novel small-molecules therapeutics to inhibit key orthogonal and synergistic oncotargets for the treatment of cancer, reported the in silico design and discovery of SRX3225, its first-in-class small-molecule potent inhibitor of three key cancer targets HDAC6, BRD4, and PI3K (Press release, SignalRx, JAN 4, 2018, http://www.ireachcontent.com/news-releases/signalrx-announces-in-silico-design-and-discovery-of-the-first-in-class-hdac6-brd4-pi3k-epigenetic-kinase-inhibitor-srx3225-668070373.html [SID1234527319]).

SignalRx’s proprietary CRIMP technology platform led to the in silico design and identification of SRX3225 within its triple inhibitor program. SRX3225 is a novel picomolar potent HDAC6 inhibitor with high selectivity over HDAC1, HDAC2 and HDAC3 isoforms (31-35 times selective) and more so against isozymes HDAC4 through HDAC11 (up to 20,000 times selective). In addition, SRX3225 potently inhibits the epigenetic target BRD4-BD1 with >5X selectivity over BRD4-BD2, and it also potently inhibits PI3K alpha and delta isoforms. Importantly, because the design of SRX3225 is achieved in silico using cancer targets’ structural data, it is possible to independently dial in and out each of the three inhibitory components in a small molecule generating dual and single inhibitory chemotypes from SRX3225.

"This is a huge immuno-oncology breakthrough because it creates a synergistic synthetic lethality effect as a result of PI3K and BRD4 and HDAC inhibition delivered with a single molecule. While dual PI3K/BRD4, dual HDAC/PI3K, and dual BRD4/HDAC inhibitors are under investigation, SRX3225 is the only triple HDAC/PI3K/BRD4 inhibitor that we know of" said SignalRx’s scientific advisor and founder Donald L. Durden, MD, PhD. "This new approach of inhibiting three targets simultaneously yields a more complete block of multiple key cancer signaling providing increased lethality coupled with less toxicity than a combination of three single agents. This novel 3-in-1 anticancer drug paves the way for more sophisticated and cost-effective combinations in cancer patients that should block development of resistance resulting in longer duration of benefits in more patients."

"We achieved this milestone by leveraging the experience in multi-targeted inhibitors and discoveries we have made in our advanced BRD4/PI3K program coupled with the knowledge we have acquired on these targets as exemplified in our recent PNAS publication (View Source)" said Dr. Joseph Garlich, Chief Scientific Officer at SignalRx. "Rational combinations of targeted agents in clinical development often face a common detrimental limitation: unwanted additive off-target toxicities from the individual agents used. This leaves no option but to reduce the effective dosages of the agents resulting in less than optimal therapeutic administrations and inefficient treatments. Our approach combines 3 drug mechanisms into one resulting in 1 single agent with a single ADME/safety profile which also simplifies and expedites its development."

SignalRx is interested in partnering discussions to quickly take these novel small molecules through clinical trials together with companion diagnostics for streamlined development and approval.
