"By combining the tissue and tumor specificity of antibodies with highly potent and catalytic targeted degradation of cancer driver proteins, we believe that DACs may represent a next generation of cancer medicine for a wide range of solid tumors and hematologic malignancies," said Arthur T. Sands, M.D., Ph.D., president and chief executive officer of Nurix. "With Seagen, our strategic goal is to advance ADC technology to the next level to provide patients with new DAC drugs that deliver greater anti-tumor efficacy and safety compared to currently available agents."

"The targeted protein degrader modality provides unique advantages over payloads currently employed across the ADC field," said Gwenn M. Hansen, Ph.D., chief scientific officer of Nurix. "This collaboration is a new application of our DELigase technology, and we are delighted to work with Seagen, a pioneer in the development and commercialization of ADC therapeutics, to create a new generation of drugs to fight cancer."

Under the terms of the agreement, Nurix will receive an upfront payment of $60 million and has the potential to receive up to approximately $3.4 billion in research, development, regulatory and commercial milestone payments across multiple programs. In addition, Nurix will be eligible for mid-single to low double digit tiered royalties on future sales, and Nurix retains an option for U.S. profit sharing and co-promotion on two products arising from the collaboration. As part of the multi-year collaboration, Nurix will use its proprietary DELigase platform to develop a suite of targeted protein degraders against multiple targets nominated by Seagen that are suitable for antibody conjugation. Seagen will be responsible for conjugating these degraders to antibodies to make DACs and advancing these DAC drug candidates through preclinical and clinical development and commercialization. Given the potential to conjugate multiple antibodies to unique degraders, several DAC drugs may be developed and commercialized within this collaboration.

With the receipt of the $60 million upfront payment, Nurix expects that its existing cash, cash equivalents and marketable securities, excluding any future potential milestones from collaborations, will be sufficient to fund its operating activities into the second quarter of 2025.

"We are thrilled to see the first molecule containing a DotBio-engineered DotBody module receive approval to enter the clinic, an important validation of our DotBody platform technology. JS207 is an exciting, highly targeted, next-generation cancer therapy that was rapidly designed using our platform technology and is just one example of how we can apply our modular approach to antibody discovery and progress it into the clinic," said Ignacio Asial, Chief Executive Officer of DotBio. "This very specific combination of anti-VEGF and anti-PD-1 addresses tumour growth and the tumour’s immune evasion tactics simultaneously. JS207 could provide a much needed new treatment option for cancer patients."

DotBio’s anti-VEGF module was discovered through the company’s patented DotBody technology platform. The platform enables the generation of multi-specific antibodies in record time, through prefabricated modules which are optimised for high stability and easy integration into more complex antibody molecules.

The modularity of the DotBody platform powers a rapid prototyping engine that compares thousands of antibody prototypes in parallel before the ideal candidate is selected for an indication. JS207 is the first next generation cancer therapy enabled by the DotBody technology to receive regulatory approval to enter clinical development.

JS207 was engineered by combining DotBio’s anti-VEGF module and Junshi Biosciences’ anti-PD-1 antibody into a single therapeutic agent, binding to both PD-1 and VEGF with high affinity. VEGF is overexpressed in most solid tumour types, leading to an angiogenic ‘switch’ where new blood vessels form around a tumour and allow it to grow exponentially. Many tumours overexpress the proteins PD-L1 or PD-L2, which suppress the immune system by binding to PD-1 present on certain immune cells. The combination therapy of a PD-1 blocking antibody and a VEGF blocking agent has shown strong efficacy in a variety of tumour types, such as renal cell carcinoma, nonsmall cell lung cancer and hepatocellular carcinoma.

JS207 inhibits the interaction between PD-1 and its ligands, PD-L1 and PD-L2, while concurrently obstructing the VEGF pathway. This dual-action mechanism allows JS207 to harness the benefits of both immunotherapies and anti-angiogenic treatments to achieve more powerful anti-tumour activity. At the time of this announcement, there is no bispecific antibody drug with similar targets that has received regulatory marketing approval.

DotBio and Junshi Biosciences entered into a commercial licensing agreement in 2022, under which Junshi Biosciences obtained licenses to develop and commercialise DotBody modules against oncology targets. JS207 has quickly achieved a number of development milestones, from engineering through to NMPA filing and approval in 18 months. Under the agreement, Junshi Biosciences has the right to generate additional therapeutic candidates using DotBio’s technology.

As JS207 moves through the clinic, DotBio is eligible to receive development-based milestone payments as well as royalties on sales following comme

About BB3008

BB3008 is a highly selective small molecule inhibitor of HPK1 with novel molecular structure developed independently by BroadenBio. BB3008 significantly activates T cell activity in vitro, shows pronounced tumor growth inhibition both as monotherapy and in combination with PD-1 inhibitors, and has excellent pharmacokinetics properties and controllable safety. The preclinical study of BB3008 was been published as "Late-Breaking Research" at the 2023 Annual Meeting of the American Association for Cancer Research (AACR) (Free AACR Whitepaper). BB3008, as monotherapy or in combination, will be used to overcome the immune suppressive tumor microenvironment and treat malignant solid tumors in clinical trials.

About HPK1

Hematopoietic progenitor kinase 1 (HPK1), also known as MAP4K1, is a serine/threonine kinase mainly expressed in immune cells (T cells, B cells, dendritic cells, macrophages, and etc.). HPK1 is a key negative feedback regulator of the T cell receptor (TCR) signaling pathway. As an important intracellular immune checkpoint, HPK1 inhibits the proliferation and functions of T cells and B cells, and also inhibits the antigen presentation by dendritic cells (DCs). Clinical studies have observed upregulation of HPK1 levels in various tumor tissues such as leukemia, bladder cancer, breast cancer, and colon cancer. HPK1 inhibition can restore the immunology functions in tumor microenvironment and enhance T cell-mediated anti-tumor immune effects. Therefore, HPK1 is a potential target for immuno-oncology therapy.

On September 7, 2023 – Daiichi Sankyo (TSE: 4568) reported that the first patient has been dosed in a first-in-human phase 1/2 trial evaluating DS-3939 in patients with several types of advanced solid tumors including non-small cell lung, breast, urothelial, ovarian, biliary tract, and pancreatic cancer (Press release, Glycotope, SEP 7, 2023, View Source [SID1234635383]).

DS-3939 is a specifically engineered potential first-in-class tumor-associated mucin-1 (TA-MUC1) directed antibody drug conjugate (ADC) designed using Daiichi Sankyo’s proprietary DXd ADC technology. TA-MUC1 is a tumor-specific transmembrane glycoprotein and is overexpressed in most human epithelial cancers, making it a promising target for cancer therapy.1,2 Currently, there are no TA-MUC1 directed therapies approved for any type of cancer.

"With DS-3939, we are pairing our unique DXd antibody drug conjugate technology with a TA-MUC1 antibody in order to evaluate this novel treatment strategy for patients with several types of advanced cancer," said Mark Rutstein, MD, Global Head, Oncology Clinical Development, Daiichi Sankyo. "The initiation of this trial is a significant milestone as DS-3939 is an important new addition to our growing DXd ADC portfolio, which now consists of six ADCs in clinical development, and represents our ongoing commitment to create new standards of care for patients with cancer."

About the Phase 1/2 Trial

The two-part, multicenter, open-label, first-in-human phase 1/2 trial will assess the safety and efficacy of DS-3939 in patients with locally advanced, metastatic or unresectable solid tumors not amenable to standard of care treatment for each tumor type.

The first part of the trial (dose escalation) will assess the safety and tolerability of increasing doses of DS-3939 to determine the maximum tolerated dose and/or the recommended doses for expansion (RDEs) in patients with locally advanced, metastatic, or unresectable solid tumors.

The second part of the trial (dose expansion) will consist of multiple expansion cohorts to continue to assess the safety and efficacy of DS-3939. The trial will evaluate safety endpoints including dose-limiting toxicities and adverse events, and efficacy endpoints including overall response rate, disease control rate, duration of response, time to response, progression-free survival and overall survival. Pharmacokinetic and biomarker endpoints also will be assessed.

The trial is expected to enroll patients across multiple sites globally, including Asia and North America. For more information, please visit ClinicalTrials.gov.

About TA-MUC1

TA-MUC1 is a tumor-specific transmembrane glycoprotein with aberrant glycosylation due to changes of the expression patterns of some sialyltransferases.1 Based on the overexpression of TA-MUC1 in most human epithelial cancers, it is an attractive target for cancer therapy.2 Currently, there are no TA-MUC1 directed therapies approved for any type of cancer. About DS-3939 DS-3939 is an investigational potential first-in-class TA-MUC1 directed ADC.

Designed using Daiichi Sankyo’s proprietary DXd ADC technology, DS-3939 is comprised of a humanized anti-TA-MUC1 antibody licensed from Glycotope GmbH, attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers.
