TapBoost® Technology: Enhanced Production for Difficult-to-Produce Proteins

PEGS Boston the essential protein engineering summit

Abstract
Therapeutic recombinant proteins produced using mammalian expression systems often have misfolding issues and are stuck in the endoplasmic reticulum by cellular quality control system, resulting in poor expression and yields. We have developed a novel technology called TapBoost® technology, which assists proper protein folding and cellular quality control systems specifically for a targeted protein. A proprietary protein (TapBoost®) is expressed together with a therapeutic protein (targeted protein), followed by the interaction between TapBoost® and the targeted protein, resulting in enhanced production of the targeted protein. TapBoost® has successfully enhanced the production of many therapeutic recombinant proteins including monoclonal antibodies and Fc fusion proteins. Importantly, monoclonal antibodies produced by the technology retained the ability to bind to the corresponding epitope, and enzymes retained their biological activity. Intriguingly, the expression of difficult-to-express proteins such as G protein-coupled receptor (GPCR) are improved by the technology and GPCR proteins expressed using TapBoost® are strongly activated after the ligand binding, and moreover the aggregation of produced proteins is significantly diminished when the aggregation-prone protein is expressed by TapBoost® technology. This unique mechanism of action enables TapBoost® to combine with other existing expression technologies to enhance the production of therapeutic proteins.

Phase 1/2a Clinical Trial of E6201

Strategia Therapeutics Initiates a Phase 1/2a Clinical Trial of the Anti-cancer Agent E6201 in Patients with Advanced Hematologic Malignancies

BOSTON–(BUSINESS WIRE) – Strategia Therapeutics, Inc. (Strategia) –  from the company’s former name,  Boston Strategics. Corp. – has begun a Phase 1/2a clinical trial of anti-cancer agent E6201 in patients with advanced hematologic malignancies, including relapsed or refractory acute myeloid leukemia (AML), high-risk myelodysplastic syndromes (MDS) and chronic myelomonocytic leukemia (CMML).  The trial is being carried out at the University of Texas M.D. Anderson Cancer Center with Gautam Borthakur, M.D., as the Principal Investigator.

There are approximately 19,000 new cases of AML in the U.S. each year, with over 10,000 deaths; the number of patients estimated to be living with AML is 40,000. Patients relapsed or refractory to currently available therapy have limited options. MDS is a type of hematological malignancy, in which the disorder of blood-forming “hematopoietic stem cells” causes inefficient production of blood cells triggering cytopenia. It is also a refractory disease for some patients with poor prognosis, progressing to acute myeloid leukemia. The U.S. incidence of MDS is 14,000 cases per year, most of them in the senior age group.

E6201, discovered by Eisai Co., Ltd., is a dual-inhibitor of FMS-like tyrosine kinase 3 (FLT-3) and mitogen-activated protein (enzyme) kinase (MEK). Activation of FLT3 is observed in patients with AML carrying either internal tandem duplication (ITD) or point (D835) mutations in the FLT3 gene, and E6201 has demonstrated activity against both mutations. The Ras/Raf signaling pathway signals through the downstream signal transducers MEK1 and extracellular signal-related kinases (ERK) and activation of this pathway is seen in AML cells of patients failing FLT3 inhibitor therapy. Preclinical studies conducted by Dr. Borthakur indicate inhibition of both pathways is important to durable responses.

The University of Texas MD Anderson Cancer Center is one of the world’s top general cancer centers with over 10,000 patients enrolled in therapeutic clinical trials each year and approximately 20,000 employees. Strategia is able to utilize the world’s top-level clinical testing functions available at the MD Anderson Cancer Center under a Strategic Alliance Agreement to carry out Phase 1 and early Phase 2 clinical trials to gain safety and preliminary proof of activity in cancer patients at an early stage. “This drug may be important for patients with advanced hematologic malignancies who have failed conventional therapeutics, including single-agent FLT3 inhibitors”, said Gautam Borthakur, M.B.B.S., Associate Professor of Leukemia at M.D. Anderson Cancer Center. By inhibition of both the FLT3 and MEK pathways we hope to provide more durable clinical benefit than through inhibition of one pathway alone. This study will build on our preclinical evidence, and further this important clinical research at our institution.” 

This is the first proprietary drug under full development by Strategia. Both FLT3 and MEK are important new targets for the treatment of advanced hematologic malignancies. Inhibition of both pathways known to be involved in the progression of FLT3 positive AML is an important next step in new targeted therapeutics for the treatment of this disease“, said Dr. Linda Paradiso, Head of Drug Development for Strategia. “We have in-licensed E6201 from Eisai Co., Ltd. and they have been an excellent collaborative partner. Both companies are fully committed to deliver breakthrough therapies using innovative approaches to achieve industry benchmark-beating timelines, quality, and financial investments for important novel anti-cancer agents”.

Company Name Change

Boston Strategic Corporation Announces Name To Strategia Therapeutics, Inc.

BOSTON–(BUSINESS WIRE) – Boston Strategic Corporation, an innovative pharmaceutical R&D company that specializes in streamlining the drug development processes, today announced its new name: Strategia Therapeutics, Inc., effective immediately.

The change, which comes on the Boston-based company’s third anniversary, more accurately reflects its emphasis on serving patients in need, says President and CEO Keizo Koya, Ph.D. “Strategia’s vision is to change the existing drug research and development paradigm,” Koya says. By creating a nimble approach to drug development, he notes, the company can reduce overall costs and time to market, thereby making new, affordable drugs available to patients whose medical needs would otherwise be unmet.

Strategia’s approach is a dramatic break from existing R&D models, which rely mainly on a single company’s in-house research, testing, and production. Instead of using one team to create many different drugs, Strategia pulls together customized global project teams for each new therapeutic agent under development. These teams, which Strategia manages, are made up of partners with specific expertise relevant to a certain drug or medical condition.

“We place drug development strategy first,” says Koya. “This approach streamlines existing research and development extensively, and it lets Strategia create new, effective therapeutics faster and more efficiently than ever before,” he adds. “Our primary goal is positively impacting patient health—so our success is measured by how quickly and effectively we make new drugs accessible to those patients,” he says.

Strategia was founded in April 2012. Since then, the company has collaborated with global partners who have the same vision and passion for improved patient care, and has advanced many new pharmaceutical R&D projects from research to clinical development. Its core team of strategists collectively have more than 200 years of experience in drug development.

The company’s new logo design and tagline (”A New Vision. A Better Future for Patients,”) symbolize its new mission.
