38 patients have been randomized in the Phase 2 part of the Phase 1/2 trial for adjuvant treatment of head and neck cancer (HNSCC1). With the primary endpoint of the trial being 2-year disease-free survival (DFS), Transgene is advancing the study and expects to communicate top line results by the end of Q1 2028.

TG4050 is designed to stimulate a strong and individualized immune response aimed at preventing relapse in patients following surgery and adjuvant (chemo)radiotherapy.

Dr. Alessandro Riva, MD, Chairman and CEO of Transgene, commented: "Completing randomization in the Phase 2 part of the study is an important milestone for TG4050 and for our myvac platform and confirms the expected readout timing of the primary endpoint of the Phase 1/2 trial by the end of Q1 2028, while we plan to release first immunological data in H2 2026. We are grateful to the patients, investigators and site personnel who contribute to advancing this promising, individualized immunotherapy. We look forward to the upcoming analyses as we continue our efforts to provide an innovative individualized treatment option for patients diagnosed with operable squamous head and neck cancer."

The primary objective of the randomized multicenter Phase 1/2 trial (NCT04183166) is to compare the efficacy of TG4050 as a single agent versus watchful waiting in the adjuvant treatment of locoregionally advanced HPV-negative head and neck cancer (HNSCC).

The primary endpoint of the trial is 2-year disease-free survival (DFS) and is expected to read out as soon as all patients from the Phase 2 part achieve 2-year follow-up from randomization unless an event (relapse, death) occurs earlier, with results anticipated by the end of Q1 2028.

Data from patients in the Phase 1 part of the trial have already shown that multiple subcutaneous injections of TG4050 were well-tolerated with no unexpected safety signals.
3-year DFS follow-up of Phase 1 patients is expected in Q2/Q3 2026.

TG4050, as a monotherapy, met all trial endpoints in the Phase 1 part of the trial and induced long-lasting immune responses to vaccine neoantigens that were sustained for up to two years after treatment initiation. All patients treated with TG4050 were disease-free at 2-years (median follow-up: 30 months), confirming robust clinical proof of principle.

The positive clinical and translational data2 suggest that individualized treatment with TG4050 has the potential to prevent cancer relapses when administered as monotherapy in an adjuvant treatment regimen in patients with high risk, resected, locally advanced HPV-negative HNSCC.

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).
