Leads Biolabs is also entitled to receive an equity stake in Oblenio Bio.

“By targeting both CD19 and BCMA in autoimmune disorders, LBL-051 has the potential to achieve a complete immune reset and superior efficacy and durability, compared to single targeting of either CD19 or BCMA alone”, said Joe Jimenez, co-founder and managing director of Aditum Bio, in the release.

Based on recent clinical data (1,2), CD19 and BCMA targeted therapies have shown compelling efficacy in difficult-to-treat autoimmune diseases, according to a company press release. Despite the promising results, however, there remains a continued unmet need for increased efficacy and durability; thus, by targeting both CD19 and BCMA, LBL-051 offers the potential to deliver stronger and more durable responses. The therapeutic is designed to deplete a broader range of pathological B-cell populations across a wide spectrum of antibody-mediated autoimmune diseases, the companies stated in the press release.

LBL-051 is a novel tri-specific T-cell engager developed from the LeadsBody Platform. Each target binding domain—CD19, BCMA, and CD3—was engineered for the express intent of enhancing safety while optimizing efficacy. These domains have been finely tuned to enhance their individual relative potency.

“LBL-051 offers a differentiated approach to treating certain autoimmune conditions and has the potential to be a Pipeline in a Product. We are pleased to establish this partnership with the high caliber team at Aditum to bring this innovative therapy to patients around the world,” said Xiaoqiang Kang, MD, PhD, founder, chairman, and CEO of Leads Biolabs, in the release.

Oblenio Bio marks the thirteenth company launched by Aditum Bio as part of the company’s missioin to give large patient populations access to important medicines.

“This collaboration with Lilly is a testament to our polyNaut platform, which is also driving a highly differentiated emerging pipeline for severe life-limiting diseases. Combining our scientific know-how to precisely deliver genetic nanomedicines targeting difficult-to-reach sites, with Lilly’s extensive drug development and commercialization expertise will accelerate the creation of novel therapies to improve patient outcomes,” said Francesca Crawford, PhD, co-founder of ViaNautis, in a company press release.

The company’s proprietary polyNaut nanovesicles are designed to precisely target specific tissues and cell types to deliver genetic materials. The technology aims to improve the current delivery of genetic medicines and hold the potential to transform treatment for various diseases, according to the company in the press release.

“I am very excited about our collaboration with Lilly to develop novel genetic medicines for patients in need. I want to thank [Crawford] and the team for their hard work in getting to this key milestone, and I look forward to working with Lilly to accelerate our shared vision of delivering targeted genetic medicines,” said Adi Hoess, MD, PhD, chief executive officer of ViaNautis, in the release. The company is currently working on a pipeline of therapeutics in the central nervous system and cystic fibrosis disease fields (1).

Nanovesicles are being researched as alternatives to extracellular vesicles (EVs) for various applications, including drug delivery. As mediators of intercellular communication, EVs have gained growing interest from researchers for their potential use in the field of regenerative medicines or as a drug delivery vehicle. However, because EVs are derived from stem cells or progenitor cells, their use is limited primarily due to a lack of efficient and scalable production methods (2).

As a result, researchers are turning to nanovesicles, particularly biofabricated cell-derived nanovesicles, as an alternative to EVs that are offer scalable, efficient, and cost-effective production (2). Meanwhile, further research has been underway to develop and test simplified and rapid production methods for cell-derived nanovesicles that offer advantages over traditional methods in terms of yield and cost-effectiveness (3), which are anticipated to offer new approaches to therapeutic drug delivery.

Shawn Li, principal scientist at Merck & Co., known as MSD outside the Unites States and Canada, talked about the importance of properly characterizing HCPs in the biomanufacturing process.

AAPS PharmSci 360: The Importance of HCP Analysis in Biomanufacturing

® spoke with Xuanwen (Shawn) Li, PhD, Principal Scientist at Merck & Co., known as MSD outside of the United States and Canada, during AAPS PharmSci 360 about the importance of properly analyzing host cell proteins (HCPs) during the biomanufacturing process.

“Host cell proteins are process-related impurities in biopharmaceutical manufacturing. The identification and control of a high-risk host cell protein in biopharmaceutical development is critical to ensure biopharmaceutical product quality and shelf life,” Li stated. For example, he explained, certain HCPs can have direct biological effect, and some HCPs can degrade the drug product or formulation excipients such as polysorbate. “The host cell protein issue can lead to significant delay or product withdrawal … Therefore, it's extremely important to understand how to properly analyze host cell proteins in biopharmaceutical manufacturing,” Li said.

, scheduled on Wednesday, Oct. 23, at 3:45 pm MT (2:45 pm PT, 5:45 pm ET), he focuses on the identification and control for one of a group of high-risk HCPs called the polysorbate-degradative enzyme. With an analytical toolbox developed at Merck, the company can better understand polysorbate degradation in biologics. One assay Li highlights in his talk is activity-based protein profiling (ABPP). “In short, ABPP can overcome the dynamic range issue of trace levels of high-risk host cell protein to drug substance and really enable the identification of those low abundance enzymes, while also providing activity information,” he said.

Attendees can visit Merck at Booth #3344. AAPS PharmSci 360 is taking place Oct. 21–23 at Salt Lake City, Utah.
