This joint development agreement was made with the goal of jointly developing treatments for cancer and inflammatory diseases using nanobody-based biopharmaceuticals. Nanobodies are antibodies that are 1/10 the size of existing antibodies, and are attracting attention as a key technology for next-generation immuno-oncology drugs because of their excellent stability and water solubility, high production yield, and high homology with human antibodies, making it easy to develop therapeutics and diagnostic platforms.

The two companies will develop new bio drugs by combining Chaperone’s nanobody technology and Dong-A ST’s new drug development platform. Chaperone builds a nanobody library based on its own technology, develops an antibody suitable for the selected target, verifies the effect at the cellular level, and then proceeds with the effect verification in an animal model in collaboration with Dong-A ST. When efficacy verification is completed in an animal model, Dong-A ST will be in charge of building a cell line for the nanobody antibody. In addition, the two companies plan to jointly discover anti-cancer targets throughout the preclinical process and evaluate the efficacy of candidate antibodies.

Lee Myung-se, CEO of Chaperone, said, "Through this MOU, we expect to see results such as the development of new biologics to treat cancer and chronic inflammation and the creation of corporate value through technology transfer." We will do our best to succeed in commercialization," he said.

Chaperon is the only domestic company that has nanobody development platform technology. In the trend of new drug development, where the structure of protein-based drugs such as bispecific antibodies or antibody drug conjugates is becoming more complex, the side effects and low production efficiency of existing antibodies can be overcome, and various routes of administration such as oral or inhalation are available. It is high tech. Based on the nanobody platform, Chaperon is developing various pipelines such as immune checkpoint inhibitory bispecific antibodies and coronavirus neutralizing antibodies.

The application is supported by positive results from the ongoing Phase 1b/2 CARTITUDE-1 study, investigating the safety and efficacy of cilta-cel.1,2 The latest results were presented at the American Society of Hematology (ASH) (Free ASH Whitepaper) 2020 Annual Meeting. Clinical development is ongoing with patients enrolled globally in various studies, including sites in Europe, the United States of America, China and Japan.1,2

"Despite advances in the treatment of multiple myeloma, there remains a high unmet need, especially for patients whose disease continues to progress," said Peter Lebowitz, M.D., PhD., Global Therapeutic Area Head, Oncology, Janssen Research & Development, LLC. "Through our collaboration with Legend Biotech, we continue to expedite the development of cilta-cel with a focus and priority on the patients who may benefit from this novel immunotherapy in the future."

CAR‑T therapy is a highly personalised treatment platform where a patient’s own T-cells are re-programmed to recognise and attack cancer cells.3 In early 2021, the EMA granted accelerated assessment for cilta-cel.4 Accelerated assessment is granted when a medicinal product is expected to be of major public health interest and a therapeutic innovation, and can significantly reduce the review timelines to evaluate an MAA.5

"Janssen has been advancing the science of oncology for more than 30 years, and we see great opportunity in the area of cell therapy and through our innovative platforms," says Mathai Mammen, M.D., Ph.D., Global Head, Janssen Research & Development, Johnson & Johnson. "We are continuing to harness our deep scientific expertise in multiple myeloma as we look to advance therapeutic options, deepen clinical responses, and drive towards improved patient outcomes."

"Today’s submission to the EMA epitomises how we strive to make a meaningful impact in the multiple myeloma landscape through advancing innovative treatments for patients," says Saskia De Haes, Vice President, EMEA Regulatory Affairs, Janssen R&D BE. "We look forward to working in partnership with health authorities, as part of the accelerated assessment process, to support these patients by ensuring timely access to the latest therapeutic options."

A Biologics License Application seeking approval of cilta-cel for the treatment of relapsed and/or refractory multiple myeloma is currently under review by the United States Food and Drug Administration.6

About Multiple Myeloma

Multiple myeloma (MM) is an incurable blood cancer that starts in the bone marrow and is characterised by an excessive proliferation of plasma cells.14 In Europe, 50,918 people were diagnosed with MM in 2020, and more than 32,400 patients died.15 Around 50 percent of newly diagnosed patients do not reach five-year survival,16 and approximately 10 percent of patients with multiple myeloma will die within one year of diagnosis.17

Although treatment may result in remission, unfortunately, patients will most likely relapse as there is currently no cure.18 Refractory MM is when a patient’s disease progresses within 60 days of their last therapy.19 Relapsed cancer is when the disease has returned after a period of initial, partial or complete remission.20 While some patients with MM have no symptoms at all, others are diagnosed due to symptoms that can include bone problems, low blood counts, calcium elevation, kidney problems or infections.21 Patients who relapse after treatment with standard therapies, including protease inhibitors and immunomodulatory agents, have poor prognoses and require new therapies for continued disease control.22

"Oral PLK4 inhibition opens a completely new approach to target therapeutic vulnerability in high risk MDS and AML and is very amenable to combination with other effective therapeutic agents," said Principal Investigator, Dr. Gautam Borthukar, MD, Professor, Department of Leukemia, Division of Cancer Medicine, MD Anderson Cancer Center.

"We are excited about the initiation of TWT-202 with our highly potent PLK4 inhibitor," said Dr. Michael Tusche, Treadwell co-CEO. "Previous clinical studies have shown that CFI-400945 can lead to single agent complete remissions in high-risk refractory AML patients. We look forward to continuing the development of this agent with the goal of delivering first in class medicines to patients in need."

The Phase 1b/2 clinical trial of CFI-400945, is an open-label, multi-center, dose optimization study designed to assess the safety, tolerability, pharmacokinetic and pharmacodynamic profiles of CFI-400945 as a single agent or in combination with azacytidine or decitabine in patients with acute myeloid leukemia, myelodysplastic syndrome or chronic myelomonocytic leukemia. The trial will enrol approximately 72 patients at up to 20 sites in North America and Asia. It will involve 3 arms including monotherapy and combination dose optimization and expansion, as well as a food effect study.

About CFI-400945

CFI-400945 is a highly potent and selective inhibitor of the serine/threonine kinase PLK4, a cell cycle kinase known to be the master upstream regulatory of centriole duplication and is critical for the maintenance of genomic integrity. PLK4 is overexpressed in a variety of solid tumors and elevated expression is associated with poor clinical outcomes. Depletion of PLK4 expression in cancer cells by RNA interference leads to mitotic defects and cell death. PLK4 was identified as a drug target based on functional screening to identify vulnerabilities of genomically unstable cancers. Anti-tumor activity of CFI-400945 has been shown in mice bearing human cancer xenografts, including robust tumor growth inhibition and durable tumor regression in primary tumor xenografts from breast cancer. CFI-400945 is a potent, selective, orally administered, first-in-class inhibitor of the serine/threonine kinase, polo-like kinase 4 (PLK4). CFI-400945 is currently in multiple investigator-initiated studies in solid and liquid malignancies,
