The collaboration combines Regeneron’s extensive biologics expertise, including bispecific antibody discovery, with Telix’s radiopharmaceutical development platform, global manufacturing capabilities and supply chain infrastructure. The collaboration will include multiple solid tumor targets from Regeneron’s portfolio of antibodies, generated from VelocImmune mice. With a shared commitment to precision oncology, the parties also plan to develop radio-diagnostics to support patient selection and treatment response assessment.

"At Regeneron, we follow the science to determine the best therapeutic approach for each disease, continuously expanding our toolbox of treatment modalities – from monoclonal and bispecific antibodies to cell therapies and beyond. Targeted radiopharmaceuticals represent a rapidly emerging frontier in oncology and an exciting opportunity to bring new treatment options to patients in need," said John Lin, M.D., Ph.D., Senior Vice President of Oncology & Antibody Technology Research at Regeneron.

"Telix brings deep expertise in radiopharmaceutical development and infrastructure that complements Regeneron’s antibody technologies and oncology portfolio," said Israel Lowy, M.D., Ph.D., Senior Vice President, Clinical Development Unit Head, Oncology at Regeneron. "Regeneron is excited to enter the targeted radiopharmaceuticals space and explore the utility of these agents either as monotherapy or rationally combined with our immunotherapy platform, particularly in areas of high unmet patient need such as lung cancer, where our PD-1 inhibitor is a global standard of care."

"The collaboration with Regeneron reflects a highly complementary set of capabilities and a unique opportunity to explore what true ‘next gen’ biologics-based radiopharmaceuticals can potentially do for patients," said Christian Behrenbruch, D.Phil., Managing Director and Group CEO at Telix. "We are well positioned to work toward the shared goal of advancing next generation precision radiopharmaceuticals for patients with hard-to-treat cancers."

Under the terms of the agreement, Telix will receive an upfront cash payment of $40 million USD from Regeneron for access to its radiopharmaceutical manufacturing platform for four initial therapeutic programs, with Regeneron having the option to expand to include four additional programs with additional upfront payments. Telix and Regeneron will share equally in the global commercialization costs and potential profits, with Telix retaining the option to co-promote certain potential products. Should Telix opt-out of the co-funding model for a particular program, it is instead eligible to receive up to $535 million USD in development and commercial milestones, plus low double-digit royalites on future net sales, for that program.

Telix and Regeneron will also jointly develop diagnostic assets, with Telix leading commercialization and Regeneron receiving a set percentage of profits.

The first poster is titled "MHC class II engager immunotherapy for the treatment of acute myeloid leukemia (Poster Board #24, Poster #5552)".

The second poster is titled "MHC class II targeted immunotherapy in the treatment of pancreatic cancer (Poster Board #23, Poster #5551)".

These presentations will focus on an MHC class II-directed strategy in hematological cancers and solid tumors designed to recruit and activate anti-tumor immune cells, with the goal of converting immunologically "cold" tumors into more inflamed, "hot" lesions that respond better to immunotherapy. The company has developed a robust preclinical data package with evidence of single agent and combination efficacy, underscoring the potential of this approach to address a major unmet need in aggressive malignancies.

Both posters will be presented during the Immunology poster session titled "Bi- and Tri-Specific Antibody Therapies" on April 21, 2026, from 2:00 p.m. to 5:00 p.m. Pacific Time in Poster Section 6 at the San Diego Convention Center.

"Acute myeloid leukemia and pancreatic cancer remain among the most lethal and treatment‑resistant cancers, and there is a pressing need for more effective and durable therapies," said Sandeep Gupta, Ph.D., Chief Executive Officer of Leukogene Therapeutics. "These AACR (Free AACR Whitepaper) presentations emphasize the potential of our MHC class II-engager platform to reshape immune responses in both hematologic and solid tumors, and they represent an important step toward bringing new immunotherapy options to patients with limited choices."

AnBogen Therapeutics to Present Dual Breakthroughs for Imofinostat (ABT-301) at AACR 2026: Addressing Immunotherapy Barriers in CRC and Chemo-resistance in Pancreatic Cancer

On April 13, 2026 AnBogen Therapeutics, a clinical-stage biotechnology company focused on precision oncology, reported that two key research abstracts regarding its lead compound, Imofinostat (ABT-301), have been selected for poster presentations at the 2026 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting. The data demonstrate ABT-301’s superior performance in enhancing immunotherapy for colorectal cancer (CRC) and reveal a novel mechanism for overcoming chemotherapy resistance in pancreatic cancer.

AnBogen will present these breakthroughs during the session "PO.ET09.01 – Epigenetic Modulators 1" on Tuesday, April 21, 2026, from 9:00 AM to 12:00 PM (Local Time) in San Diego.

1. Strengthening Immune Response: New Evidence in Colorectal Cancer (CRC)

Abstract Title: Imofinostat in combination with immune checkpoint inhibitors enhances anti-tumor activity in colorectal cancer
Abstract Number: 4496 (Section 14, Poster 15)
Key Breakthrough: Preclinical data confirms that Imofinostat, acting as an HDAC inhibitor, effectively modulates the tumor microenvironment (TME). By synergizing with immune checkpoint inhibitors and anti-angiogenic agents, it converts "cold tumors" into "hot tumors," significantly enhancing the immune system’s ability to recognize and eliminate cancer cells. This provides a robust scientific foundation for AnBogen’s ongoing global clinical trials.
2. Breaking the Defense: Targeting the HDAC3-NRF2 Pathway in Pancreatic Cancer

Abstract Title: Imofinostat enhances chemotherapy response in KRAS-mutant pancreatic ductal adenocarcinoma (PDAC) by targeting the HDAC3-NRF2 pathway
Abstract Number: 4497 (Section 14, Poster 16)
Key Breakthrough: For highly challenging KRAS-mutant pancreatic cancer, the study reveals that Imofinostat precisely regulates the HDAC3-NRF2 signaling pathway—a key driver of chemo-resistance. By intervening in this pathway, Imofinostat significantly boosts tumor sensitivity to chemotherapy, offering a promising new therapeutic strategy for patients with this aggressive malignancy.
Triple Combination Strategy for Advanced CRC

Based on the strong scientific evidence presented at AACR (Free AACR Whitepaper), AnBogen is actively advancing a Phase 1/2 global multi-center clinical trial (NCT07244705) for Imofinostat in combination with Tislelizumab (an anti-PD-1 monoclonal antibody provided by BeOne Medicines under a clinical drug supply agreement) and an anti-angiogenic agent for advanced CRC.

This triple combination strategy leverages ABT-301’s capacity to reshape the tumor microenvironment and lift immune suppression, which in turn unlocks the therapeutic potential of the PD-1 inhibitor. Through a synergistic interplay with anti-angiogenic agents, the treatment collectively promotes the normalization of tumor vasculature and optimization of the microenvironment. This integrated action effectively dismantles drug delivery barriers, allowing immune cells to penetrate deeper into the tumor core for maximum anti-cancer synergy.

"The two abstracts presented at AACR (Free AACR Whitepaper) this year represent international academic recognition of ABT-301’s innovative mechanism," said John Hsu, CEO of AnBogen Therapeutics. "We are accelerating the translation of these findings into clinical results. Furthermore, our recent successful Series B funding and upcoming plans for an Emerging Stock Market listing will provide the resources needed to drive our trials forward and address significant unmet medical needs."

About Imofinostat (ABT-301) Imofinostat is a small-molecule Histone Deacetylase inhibitor (HDACi). It reactivates tumor suppressor genes silenced by cancer cells, inducing apoptosis and inhibiting tumor growth. In Phase 1 monotherapy trials, ABT-301 demonstrated excellent safety and competitive advantages across various solid tumors.

Currently, a global multi-center Phase 1/2 clinical trial (NCT07244705) is underway to evaluate the safety and efficacy of Imofinostat in combination with Tevimbra (Tislelizumab) and Bevacizumab. This study focuses on patients with proficient mismatch repair (pMMR) or non-high microsatellite instability (Non-MSI-H) metastatic colorectal cancer (mCRC).
