On April 9, 2025 Infinitopes Ltd reported that the UK Medicines and Healthcare products Regulatory Agency (MHRA) has granted Clinical Trial Application (CTA) approval for the first-in-human Phase I/IIa clinical trial of ITOP1, the company’s lead ‘off-the-shelf’ cancer vaccine (Press release, Infinitopes, APR 9, 2025, View Source [SID1234651861]). ITOP1 is a precision cancer vaccine, designed to safely and accurately target tumour antigens, leveraging the company’s vector delivery system, aiming to drive strong and durable T-cell protection for patients with surgically resectable oesophageal adenocarcinoma (OAC).

The vaccine is designed to stimulate a robust immune response, including activation of CD8+ cytotoxic T cells, to eliminate residual cancer cells expressing the target antigens, reducing the risk of disease recurrence. Tumour antigen targets for ITOP1, Infinitopes’ lead asset from its Precision Immunomics platform, are derived using the company’s bespoke AI/ML-driven immunopeptidomics approach and demonstrate high tumour-specificity and inter-patient conservation with potential clinical applicability across multiple cancer types.

The VISTA* study is a phase I/IIa double-blind, randomised, placebo-controlled trial to assess the safety, tolerability and anti-tumour activity of ITOP1 in reducing OAC recurrence rates. 60 patients will receive ITOP1 in a prime/boost regimen, in combination with the best standard of care, i.e., a priming dose following neoadjuvant and a boost dose before adjuvant FLOT (fluorouracil, leucovorin, oxaliplatin, and docetaxel) chemotherapy. Infinitopes’ VISTA trial will be one of the first in the world to administer a cancer vaccine in the neoadjuvant setting while the primary tumour remains in situ, unlocking the potential for enhanced protection from epitope spreading.

The multicentre VISTA study will be conducted at specialist cancer centres in the UK under the leadership of Prof Mark Middleton, a world-renowned Chief Investigator. The VISTA* study is set to commence in Q2 2025. For further details, visit the UK Clinical Trials Registry for Integrated Research Application System (IRAS) project 1008088.

Prof Mark Middleton, Chief Investigator, Head of Oncology & Co-director, CRUK Oxford Centre, University of Oxford, and Scientific Advisory Board Member for Infinitopes, said: "Half of us will suffer cancer in our lifetimes, so we need better, affordable treatments for the disease. ITOP1 is an exciting new immunotherapy with the potential to make a difference across a wide range of cancers, bringing hope to many patients. This first trial in oesophageal cancer will evaluate ITOP1’s precision targeting, which enables anti-tumour immunity through epitope spreading to tackle residual cancer cells and prevent recurrence. We are particularly excited that, by working with the MHRA, we can test ITOP1 where we believe it will achieve the best protection, in potentially curable disease."

Dr Jonathan Kwok, Chief Executive Officer & Co-Founder at Infinitopes, commented: "We are delighted that we have advanced our lead vaccine candidate, ITOP1, from university research to a groundbreaking clinical programme in just over three years. This marks a major performance milestone for the company, bringing Infinitopes an important step closer to offering lifesaving solutions for patients with oesophageal and other aggressive cancers. This achievement is a testament to the power of our team, across immunopeptidomics, computational biology/AI/ML, immunology, oncology, advanced trial design, and our collaborations with Cancer Research UK and leading centres around the world."

Infinitopes recently strengthened its scientific and clinical team with the appointments of exceptional industry leaders, Dan Menichella and Jo Brewer, PhD, supporting the company’s ambition to advance ITOP1 through clinical development to prolong survival and improve the quality of life for patients.

Dan Menichella, Non-Executive Director at Infinitopes, noted: "Infinitopes’ Precision Immunomics approach has the potential to revolutionise cancer treatment as we know it today. I am very excited for the start of our VISTA study, to validate our ITOP1 vaccine and the fundamental enabling technologies."

"Glioblastoma remains one of the most aggressive and challenging cancers to treat, and we are committed to advancing novel immunotherapy approaches that have the potential to make a meaningful impact for patients. The results of this Phase I analysis are highly encouraging and reinforce the potential of DOC1021 as a novel immunotherapy for glioblastoma."

Abstract Presentation Details:

Title: Phase I Analysis of DOC1021, a Cell-Based Vaccination Platform for Adjuvant Therapy of Glioblastoma
Authors: Zhu J-J, Esquenazi-Levy Y, Hsu S, Zvavanjanja RC, Vu M, Schumann EH, Trivedi A, Liu W, Namekar M, Hofferek CJ, Ernste K, Mossop C, Clay CM, Amin S, Ravi V, Kemnade JO, Aguilar LK, Turtz A, Tandon N, Konduri V, Georges JF, Decker WK
Session: S29 – Neuro-oncology
Date and Time: Tuesday, April 8, from 4:06-4:18 p.m. PT
Location: San Diego Convention Center, 25C
Key Highlights:

DOC1021 vaccines were administered to 16 newly diagnosed glioblastoma patients, with 94% (15/16) being MGMT unmethylated.
No adverse events greater than Grade 2 attributable to the investigational regimen and no dose-limiting toxicities (DLTs) were observed.
CD4+ (13/13) and CD8+ (11/13) central memory T-cell compartments expanded post-vaccination (p<0.002 and p<0.05, respectively), indicating robust immune activation.
CD8+CD127+ memory precursor effector cells (MPECs) expanded in 12/13 patients (p<0.001), suggesting enhanced immune memory potential.
Spatial transcriptomics analysis of three patients showed intense CD25+ foci overlapping effector memory T-cell and migratory microglial markers post-vaccination.
One-year overall survival (OS) rate in the 15/16 unmethylated cohort was 88%, compared to 53% in an age-matched control cohort (p<0.002), highlighting a potential survival benefit.
"In the Phase I trial, the dendritic vaccine injections at the lymph nodes were well tolerated, with no significant side effects observed in any participants," said Dr. Jay-Jiguang Zhu, Principal Investigator of the study and Professor and Director of Neuro-oncology at UTHealth Houston. "We are looking forward to assessing this dendritic cell-based vaccine therapy in the upcoming Phase II trial."

About DOC1021

DOC1021 is an autologous dendritic cell vaccine (DCV) that initiates a complete cytotoxic TH1 immune response against a patient’s cancer through the company’s proprietary double loading technology. The vaccines are made with a patient’s dendritic cells combined with mRNA and proteins prepared from freshly obtained patients’ tumor specimens.

This unique approach unlocks a synergistic tumor killing TH1 response driven by dual protein and RNA antigen sourcing, and it allows targeting of the complete cancer antigen pool. Moreover, the approach does not require any molecular modification of the patient’s immune cells for manufacturing, and does not require preconditioning of bone marrow or high dose IL-2 for administration.

In addition to the lead GBM study, a clinical trial of another Diakonos dendritic cell vaccine is ongoing for the treatment of pancreatic cancer. Diakonos has received Fast Track designations from the FDA for both the GBM and pancreatic cancer programs. The company has also received Orphan Drug Designation for the GBM program.
