In the poster, entitled "EGL-001 is a novel immunocytokine designed to specifically target and disarm T regulatory cells in the tumor microenvironment".

Egle scientists present evidence that EGL-001, a CTLA-4 targeted IL-2 dominant negative mutein, selectively binds to T regulatory (Treg) cells and inhibits Treg IL-2 signaling.

The resulting reduction of Treg frequencies and functionality, as observed in ex vivo human tumor cultures and in vivo mouse models, promotes effector T cell responses. Accordingly, EGL-001 induces anti-tumor responses in combination with anti-PD-1 treatment in mouse models.

EGL-001 is the first drug candidate to emerge from Egle’s discovery platform, and it’s being developed for treatment of advanced solid tumors and to restore responsiveness to PD-1 inhibition.

In the fall of 2023, very promising data from the ongoing phase 1b/2a study with Medivir’s spearhead project fostrox in combination with Lenvima were presented. The combination has shown continued improved clinical benefit in patients with advanced primary liver cancer (HCC) and at ASCO (Free ASCO Whitepaper)-GI in January 2024, data were presented showing further increases in the proportion of patients achieving a clinically relevant reduction in their liver tumor and patients staying on treatment longer with stopped tumor growth. This attracted very strong interest and the data has improved further in the first quarter of 2024.

The clear clinical benefit and great medical need present an opportunity to accelerate the clinical development of fostrox with the ambition of becoming the first approved pharmaceutical therapy for the second-line treatment of HCC, a market worth ~$2.5 billion annually. These efforts to bring fostrox closer to potentially accelerated approval are Medivir’s absolute focus in the continued clinical development. In addition to fostrox, which is carried out by the company, several of the projects that Medivir has licensed out to partners will also enter the clinical phase in 2024.

This and much more can be found in Medivir’s Annual Report 2023, published today at the website;

"We are thrilled to join forces with Merck KGaA, Darmstadt, Germany, to discover targets with the first-in-class potential to advance the next wave of transformational ADC therapeutics," said Brian Lamon, PhD, Chief Business Officer of Caris. "This partnership adds to our portfolio of external pipeline programs and is a strong validation of our highly differentiated, orthogonal multi-omics approach to discovering truly novel targets that may be harnessed to eradicate tumors."

Under the terms of the agreement, Merck KGaA, Darmstadt, Germany, will provide Caris with an upfront payment as well as research funding. In addition, Caris will be eligible for discovery, development, regulatory and sales-based milestone payments that may total up to $1.4 billion along with tiered royalties. Merck KGaA, Darmstadt, Germany will receive an exclusive global license to develop, manufacture and commercialize ADC therapeutics for selected targets.

"We are dedicated to addressing high unmet needs across multiple cancer types," said Paul Lyne, Global Head of Research Unit Oncology for the Healthcare business sector of Merck KGaA, Darmstadt, Germany. "Through close collaboration with Caris, utilizing their unique discovery platform, we complement our internal ADC capabilities to develop novel first-in-class ADCs and ultimately strengthen our potential to expand our oncology portfolio."

Caris Discovery leverages the scale of Caris’ core molecular profiling business to discover novel, druggable targets that would be otherwise inaccessible through more traditional approaches. Through the convergence of its proprietary ADAPT Biotargeting platform, a contemporaneous patient tissue repository, a suite of sophisticated AI and machine learning capabilities, and its dedicated 59,000 square foot discovery research laboratory, Caris Discovery aims to identify and validate new therapeutic targets that can be harnessed by its biopharma partners to develop the next generation of oncology therapies. Under this partnership, targets discovered and validated by Caris can be pursued by Merck KGaA, Darmstadt, Germany. Merck KGaA, Darmstadt, Germany will be responsible for the preclinical and clinical research, as well as the development and commercialization of drug candidates emanating from these programs.

"Caris Discovery is uncovering novel unexplored targets in patient populations where precision therapeutics have yet to be developed," said Milan Radovich, PhD, Senior Vice President and Chief Scientific Officer at Caris. "We are proud to be working closely with Merck KGaA, Darmstadt, Germany, to bring new therapeutic options to cancer patients together."

On April 4, 2024 Aethon Therapeutics, Inc., a biotechnology company discovering and developing novel antibody therapeutics designed to attack cancer cells in tandem with targeted covalent inhibitor cancer therapies, reported that it has entered into a collaboration agreement with Revolution Medicines, Inc., a clinical-stage oncology company developing targeted therapies for patients with RAS-addicted cancers (Press release, Aethon Therapeutics, APR 4, 2024, View Source [SID1234641799]). Under the terms of the agreement, Aethon will use its HapImmune platform to discover novel bispecific antibodies to mount an immune attack directed towards cancer cells hit by Revolution Medicines’ RAS(ON) inhibitors, with the goal of fueling tumor clearance and helping to establish immune memory.

The terms of the agreement provide for a multi-year collaboration under which Aethon is responsible for conducting preclinical work, with full reimbursement by Revolution Medicines. Revolution Medicines has an option to conduct any clinical development of products that may arise from the collaboration. The arrangement provides for both upfront and potential downstream payments covering future development and commercialization activities should Revolution Medicines exercise its option.

"Aethon has proprietary expertise in creating and developing novel, cancer-specific drug-target peptide conjugates that seek out and bind to neoantigens created by different classes of covalent inhibitor anti-cancer therapies. This collaboration with Revolution Medicines represents an important validation of Aethon’s HapImmune platform and an exciting opportunity to potentially enhance RAS targeting by combining the power of highly selective immune cell attack with Revolution Medicines’ novel RAS(ON) inhibitors," said Raj Chopra, M.D., Ph.D., CEO of Aethon Therapeutics and Head of Oncology and Venture Partner at Apple Tree Partners.

"We are delighted to have the opportunity to work with Aethon and exploit their novel and innovative platform," said Steve Kelsey, M.D., president, research and development at Revolution Medicines. "Through our own publications, and those of other leaders in the field, we have become increasingly aware of the interaction between oncogenic RAS activation and anti-tumor immunity. This collaboration represents an important component of our long-term vision to optimize treatments for patients with RAS-driven cancers."

Beyond the programs being advanced in partnership with Revolution Medicines, Aethon has additional programs targeting validated covalent small molecules that inhibit RAS, EGFR, and BTK. "Aethon is discovering its own proprietary covalent inhibitors that target known oncogenes and tumor suppressors to create cancer-specific neoantigens as targets for engaging the immune system. This includes CD3+T cells and T cell subsets. Our significant progress on this front is very encouraging," Dr. Chopra said.
