"We believe the receptor tyrosine kinase FLT3 is among the most attractive targets in AML but is largely untapped as a target for T cell engaging antibodies," stated Jennifer Michaelson, Ph.D., Chief Development Officer, Biologics at Cullinan Oncology. "Given CLN-049’s robust preclinical package and ease of manufacturability, we believe this bispecific antibody has the potential to be a superior treatment option for AML patients. We are looking forward to filing an IND for CLN-049 by year end."

AML is a rapidly progressing cancer that forms in the bone marrow and results in an increased number of abnormal white blood cells in the bloodstream and bone marrow. AML remains one of the most challenging blood cancers, with high unmet medical need due to low median survival rates in patients. FLT3 is expressed on leukemic cells from the majority of AML patients, including prominent expression on leukemic progenitor cells.

FLT3 is a commercially validated target in AML, yet unlike small molecule inhibitors targeting FLT3, a T cell engaging antibody like CLN-049, which binds to the extracellular domain of FLT3, is agnostic to mutations in the intracellular signaling domain, opening up a broader patient population and avoiding resistance mechanisms. FLT3 has potential advantages over the more commonly selected target antigens for T cell engagers, such as CD33 and CD123, given the low-level expression of FLT3 on normal myeloid cells and hematopoietic stem cells. CLN-049 is therefore predicted to have an improved safety profile.

"We’ve long held the belief that FLT3 is among the most attractive targets in AML," stated Helmut Salih, DKFZ/DKTK Professor and physician at Tübingen University Hospital, and Gundram Jung, Professor at Tübingen University, the originators of the molecule. "And we look forward to advancing CLN-049 into clinical testing with the help of the Cullinan team given their deep domain expertise in the bispecific field."

In this role, VAI will assemble and distribute kits for the collection of tumor tissue, blood and other biospecimens to hospitals and medical centers around the U.S. Once samples are collected from volunteers, they will be shipped to VAI for processing and either stored for later study or sent to other organizations conducting analyses for the Cancer Moonshot. In all, the Biobank project is expected to collect biospecimens from more than 1,000 participants.

"Biospecimens are the bedrock of scientific research — without them, we wouldn’t be able to study cancer or develop new treatments and diagnostics," said Scott Jewell, Ph.D., director of VAI’s Core Technologies and Services, which includes the Institute’s Biorepository. "We are honored to be part of the Cancer Moonshot Biobank study and look forward to doing our part to support research and improve cancer care."

The Cancer Moonshot was launched in 2016 by the Obama Administration. Its strategic aims, determined by a Blue Ribbon Panel of experts, are designed to answer critical scientific and medical questions while ensuring the samples collected represent the diversity of the U.S. population.

VAI’s Biorepository provides services for a number of large-scale national and international projects, including NIH’s Clinical Proteomic Tumor Analysis Consortium and the National Cancer Institute’s Biospecimen Pre-Analytical Variables Program. The Biorepository team also played an integral role in biospecimen collection for the NIH’s Genotype-Tissue Expression project, including developing and shipping the kits used by investigators around the country to collect tissue samples. It currently serves as the biobank for the Multiple Myeloma Research Foundation’s CoMMpass Study, the Tuberous Sclerosis Alliance and the Van Andel Institute–Stand Up To Cancer Epigenetics Dream Team. Since 2012, VAI’s Biorepository has been accredited by the College of American Pathologists (no. 8017856), which provides objective assurance that VAI meets or exceeds the high standards set by CAP.

The project has been funded in whole or in part with federal funds from the National Cancer Institute of the National Institutes of Health under contract no. HHSN261201500003I, Task Order HHSN26100042 through Leidos Biomedical Research, Inc. under subcontract no. 20X062Q.

"At Ryvu, we always excelled in moving forward at a rapid pace; however, the first half of 2020 was an exceptionally eventful and intensive period for us. We have managed to achieve a couple of significant clinical milestones such as successful completion of Phase I for SEL24/MEN1703 in acute myeloid leukemia, as well as the receipt of an Orphan Drug Designation for SEL120 for the treatment of AML patients.

"We announced a collaboration with Galapagos focused on the discovery and development of novel small molecule drugs in inflammation. In June, we completed the construction of the R&D Center for Innovative Drugs and subsequently moved into our new laboratories and offices. Soon afterward, we have announced our updated development strategy for 2020-2022, which was followed by the issue of series I shares and raise of over USD 36 million of new capital" – commented Pawel Przewiezlikowski, Chief Executive Officer of Ryvu.

"We have also secured additional non-dilutive grant financing to support the development of our targeted immuno-oncology program. Despite the global pandemic, we participated in numerous scientific and business conferences presenting very good data from our early pipeline projects. What is exceptional is that we managed to do all of this and much more during the ongoing COVID-19 pandemic, including the continuation of SEL120 Phase I study in AML/MDS in the U.S.

"The epidemiological situation required us to adopt numerous preventive measures across our entire organization to keep our scientists safe and, at the same time, assure business continuity. I believe we passed that test with flying colors, and I am proud of the work we have done at Ryvu in these six months" – adds Przewiezlikowski.

Recent Achievements

On February 21, Ryvu signed a grant agreement for the development of targeted oncology therapies based on the synthetic lethality concept. This grant provides Ryvu with almost USD 8.3 million of non-dilutive financing to discover, develop, and select a clinical candidate targeting cancers which had been considered in the past as largely undruggable using rational approaches. The total net value of the project amounts to USD 14 million, and the anticipated project duration is until December 2023.
On March 5, Menarini Group announced the successful completion of Phase I clinical study of SEL24/MEN1703 in Acute Myeloid Leukemia, which entitled Ryvu to receive a USD 1.96 million milestone payment. The full data from the study was be presented as a poster "Results of the dose escalation part of DIAMOND trial (CLI24-001): First-in-human study of SEL24/MEN1703, a dual PIM/FLT3 kinase inhibitor, in patients with acute myeloid leukemia" during the Virtual 25th EHA (Free EHA Whitepaper) Congress taking place June 11-21. Throughout the dose escalation part, SEL24/MEN1703 showed an acceptable safety profile up to the recommended dose established at 125 mg/day (14 days ON – 7 days OFF in 21-days cycles). Initial evidence of single agent efficacy was observed with 1 CR and 1 CRi in elderly patients who had exhausted standard therapeutic options. A cohort Expansion study planned in relapsed/refractory AML patients in the United States and Europe, including Poland, will further investigate the single agent activity and the safety profile of SEL24/MEN1703.
On March 27, the U.S. Food and Drug Administration (FDA) granted an orphan drug designation (ODD) to Ryvu’s SEL120 for the treatment of patients with acute myeloid leukemia (AML).
On April 15, Galapagos NV (Euronext &NASDAQ: GLPG) and Ryvu Therapeutics announced a collaboration focused on the discovery and development of novel small molecule drugs in inflammation. Ryvu will contribute its biology and chemistry platform as well as related intellectual property to the program. During the joint research collaboration, Ryvu is responsible for early drug discovery, and Galapagos will be responsible for all further development of the program.
On June 2, Ryvu obtained the occupancy permits for its newly built R&D Center for Innovative Drugs, meaning it has completed the construction of the facility. Subsequently, Ryvu has initiated its move to the new headquarters.

"This is an important milestone for Transcenta as we continue to develop and implement a highly productive perfusion platform using in-house developed chemically defined media to our pipeline programs," said Dr. Chris Hwang, CTO of Transcenta. "Given the high volumetric productivity of our perfusion processes, typical pre-pivotal clinical demand can be met with < 200L scale single-use bioreactor (SUB) while commercial supply can be met with 500L scale SUB."

This is another breakthrough for Transcenta’s perfusion platform after achieving productivity to greater than 4 g/L per day for multiple cell lines earlier this year. Transcenta will work on developing innovative technology like Integrated Continuous Bioprocessing and improving development and manufacturing capability to help accelerate new biologics’ clinical progress, moving forward to our mission of employing cutting edge technology to deliver speed and affordable high-quality innovative biologics to patients around the world.
