Oxford BioTherapeutics Announces Research Collaboration with ImmunoGen to Develop Novel Antibody-Drug Conjugates

Oxford BioTherapeutics | June 14, 2022

Oxford BioTherapeutics (OBT), a clinical stage oncology company with a pipeline of immuno-oncology and Antibody Drug Conjugate (ADC)-based therapies, today announced a multi-year collaboration to research, develop and commercialize novel, first-in-class ADCs with ImmunoGen (IMGN), a leader in the expanding field of ADCs for the treatment of cancer. The companies will utilize ImmunoGen's linker-payload technology directed to novel targets identified via OBT's proprietary OGAP® discovery platform. The companies will support these R&D efforts through joint funding and by combining their respective proprietary technologies.

"I am very enthusiastic about our new partnership with ImmunoGen, a leader in the development of ADCs," said Christian Rohlff, PhD, Chief Executive Officer (CEO) of Oxford BioTherapeutics. "The company's expertise, in combination with the unique targets from our OGAP® database, provides potential to strengthen our respective drug pipelines with novel and highly differentiated ADCs for cancer patients in need of novel therapeutic options."

As part of the agreement, OBT will receive an upfront payment from ImmunoGen, reflecting OBT's preclinical programs to be included in the partnership.

In addition, once antibodies generated by OBT have been coupled with ImmunoGen's proprietary linker-payload technology, each company will have the opportunity to select one or more development programs to further develop on its own.

Each company is eligible to receive milestone payments based on the achievement of pre-specified development, regulatory, and commercial milestones, as well as tiered royalties as a percentage of worldwide commercial sales, with respect to each program selected by the other company. Once a company has chosen a given program, it will be solely responsible for all R&D costs associated with the specific program.

"OBT has demonstrated expertise in identifying novel targets for the development of specific antibodies – two key components to generating successful ADCs," said Stacy Coen, ImmunoGen's Senior Vice President and Chief Business Officer. "This expertise, combined with ImmunoGen's portfolio of cancer-killing payloads and linkers, will be instrumental as both companies work to develop novel ADCs designed to address cancers with high unmet need. We look forward to working with OBT as we expand and diversify our investment in ADC research capabilities, deepen our pipeline, and transition to a fully-integrated oncology company."

ImmunoGen's portfolio is comprised of next-generation maytansinoid, DNA-acting, and novel camptothecin toxins and proprietary linkers. This collaboration will utilize novel targets identified by OBT combined with ImmunoGen's proprietary toxins and associated linkers. OBT has clinical experience with ImmunoGen's ADC platform and DM4 payload, which is utilized in OBT's lead program OBT076, an ADC currently in clinical trials as a monotherapy, as well as in combination with checkpoint inhibitors, in patients with advanced or refractory solid tumors, including gastric, bladder, ovarian, and lung cancer.

About Oxford BioTherapeutics

Oxford BioTherapeutics is a clinical stage oncology company based in Oxford, UK; San Jose, CA and Morristown, NJ, USA; with a pipeline of first-in-class immuno-oncology (IO) and antibody-drug conjugate (ADC) based therapies designed to fulfil major unmet patient needs in cancer therapeutics.

OBT's lead clinical program, OBT076, an ADC utilizing an Immunogen toxin, initiated expansion in a U.S. Clinical Trial in 2021 in patients with advanced or refractory solid tumors, including gastric, bladder, ovarian and lung cancer, where CD205 is overexpressed. Infiltration of tumors by immunosuppressive cells correlates with adverse outcomes (lower progression free and overall survival), suggesting that this process contributes to the progression of several cancers.

CSL Plasma Reimagines Donor Experience With First Donations Completed on Innovative Plasma Collection Technology

CSL Plasma | August 08, 2022

CSL Plasma, the plasma collection business of global biotherapeutics leader CSL Behring, began a new era in plasma donations, collecting its first plasma donations using leading-edge plasma collection technology that is expected to significantly reduce average collection time – by approximately one-third – and improve the donor experience. The Rika Plasma Donation System, only available at CSL Plasma and developed by Terumo Blood and Cell Technologies, is designed to reduce collection time, and improve the donor and operator experience. When considering prior average CSL Plasma donation procedure times, this could represent about a 30% reduction in average donation time for donors. The new plasmapheresis system first launched today in the Aurora, Colorado, CSL Plasma location, as part of a phased rollout to CSL Plasma U.S. collection centers. Plasma collected at CSL Plasma facilities is used in the manufacturing of lifesaving plasma-derived therapies. "Today marks a threshold moment for plasma donors following years of dedication, innovation and collaboration – demonstrating how we are driven by our promise in delivering lifesaving and life-extending therapies to patients around the world. We look forward to the positive impact this new technology brings and are thankful for plasma donors who continue to do the amazing every day when they donate at CSL Plasma." CSL Chief Operating Officer Paul McKenzie CSL Plasma believes features of the new Rika system can enable the collection of more plasma, in shorter periods of time, supporting quality and safety, and, ultimately, better serving patients who rely on plasma-based therapies. One of the first plasma donors to experience the Rika system, Kelly Geiser is a resident of the Denver area. She has donated plasma since 2017, and is a Platinum level donor as part of CSL Plasma's donor loyalty program, iGive Rewards®. Geiser appreciated that she was able to complete the donation procedure with the new technology in under 35 minutes and in the fastest donation time she has experienced, while every plasma donor's experience will vary. Donating plasma is also personal for Geiser, who says that therapies made from plasma have helped her and her family, including a parent who recently underwent emergency surgery. "It feels good knowing I'm helping people and, who knows, I might've helped somebody I know," said Geiser. According to Terumo BCT, benefits of the Rika Plasma Donation System include Rika completes one plasma collection in 35 minutes or less on average. The proprietary design of the system's centrifuge maximizes the plasma yield per cycle. The Rika Plasma Donation System was designed to allow no more than 200 milliliters of blood cells outside the donor's body, resulting in a low extracorporeal volume, which may contribute to a more comfortable donor experience. With less than 200 milliliters of blood cells outside the donor's body at any given time, should the initial procedure not be completed, the donor can return and donate without being deferred. The device is designed with an advanced user interface to guide CSL Plasma front-line employees. Operators can quickly and confidently resolve alarms, thanks to guidance provided on the Rika system's touchscreen, which also alerts operators about situations that require attention and provides suggested actions to resolve the situation. The system allows for real-time data analytics to drive device maintenance and repairs. CSL Plasma is implementing the new devices at Colorado centers and then expanding to other U.S. locations, providing donors more opportunities to "do the amazing" and be rewarded for their generosity. "As a long-time leader in our industry, CSL Plasma looks forward to this new plasmapheresis technology to delight our plasma donors and attract new donors while supporting a better operating experience for our employees," said Walter Charles, CSL Plasma Senior Vice President and General Manager. "As we complete the implementation of new technology at U.S. centers, we continue to address the critical and ongoing need for human plasma to produce life-saving medicines for people with serious and rare diseases."
