CancerCancer Research UK, Vaccitech plc (Nasdaq: VACC) and the Ludwig Institute for Cancer ResearchCancer Research (Ludwig), today announce the first patient dosed in the MAGE trial, which is testing a novel immunotherapeutic, VTP-600, in patients with the most common type of lung cancer.
The phase I/IIa trial is expected to enroll approximately 86 people who have been newly diagnosed with non-small cell lung cancer (NSCLC) and will be testing the safety and initial efficacy of VTP-600 in these patients. VTP-600 will be given in combination with the current first line treatment for NSCLC.
If further clinical trials are successful, VTP-600 could prove to be a powerful new treatment for a group of patients in need of better options.
Cancer Research UK’s Centre for Drug Development (CDD) is managing and providing significant funding for the phase I/IIa trial. Vaccitech Oncology Limited (VOLT), a strategic collaboration between Vaccitech and Ludwig, are supplying VTP-600 for the trial.
The Chief Investigator for the trial is Professor Fiona Blackhall, Professor of Thoracic Oncology and Honorary Consultant in Medical Oncology, at The Christie NHS Foundation Trust.
VOLT holds an option to license the results of the trial to aid future clinical development and commercialisation of the immunotherapy. If VOLT elects not to exercise its option, CancerCancer Research UK will have the right to take the programme forward in all cancer indications.
Unlike preventative vaccines, such as the influenza vaccine, which is given to healthy people to protect them against future disease, VTP-600 is given to people who already have lung cancer.
It does this by delivering cancer-associated proteins — known as MAGE-A3 and NY-ESO-1 antigens — to antigen presenting cells (dendritic cells), causing the immune system to produce cytotoxic T cells which are able to target and kill cancer cells expressing these antigens.
It cannot target healthy tissues because MAGE-A3 and NY-ESO-1 are not found on non-cancerous cells.
VTP-600 is a ‘prime-boost’ immunotherapy, meaning an initial ‘prime’ dose is administered, and then a second ‘booster’ dose is given 21 days later. This ‘prime-boost’ approach is expected to improve the size and length of the anti-cancer immune response.
Even though two doses are administered, the immunotherapy comprises three parts. ChAdOx1-MAGE-A3-NY-ESO-1 is the prime immunotherapy administered to all patients, MVA MAGE-A3 with or without MVA NY-ESO-1 is given as the second booster immunotherapy, depending on the type of antigens expressed on the patient's tumour.
In the prime dose, ‘ChAdOx1’ refers to the viral vector used in the vaccine to deliver the antigens. It is a virus which causes a common cold in chimpanzees, but it has been modified so that it can no longer cause disease. ChAdOx1 is the same viral vector used in the Oxford/AstraZeneca Covid-19 vaccineCovid-19 vaccine (which was co-invented by Vaccitech) and is being used in phase II trials for other diseases.
The trial is expected to run over 2-3 years. More information on the clinical trial can be found at NCT04908111.
Dr Nigel Blackburn, Director of Cancer Research UK’s Centre for Drug Development, said: “We are excited to see that the first patient has been treated with the VTP-600 immunotherapeutic vaccine. NSCLC is the most common type of lung cancer but remains very hard to treat. If successful, this cutting-edge immunotherapy could provide an effective, much-needed new treatment to help more people survive their lung cancer.
Chief investigator for the MAGE clinical trial, Professor Fiona Blackhall, who is consultant medical oncologist and director of research and innovation at The Christie NHS Foundation Trust, said: “There is an urgent need to find better treatments for patients with NSCLC. The VTP-600 immunotherapeutic vaccine is a cutting-edge technology to target a patient’s immune system to tackle the cancer cells. The trial is planned to open at 10 specialist hospitals across the UK to ensure that as many patients as possible can be given opportunity to participate.”
Vaccitech’s CEO, Bill Enright, said: “We are delighted with the start of this trial, arising from our clinical development partnership with two of the world’s most prestigious cancer research institutions. We’ve seen how our viral vector has transformed the world’s approach to sars-cov2 and has shown promising early results in chronic hepatitis B virus infection. We see this partnership as another important validation of our prime boost platform’s utility in oncology as well as infectious disease.”
“We are pleased that the research arising from the Ludwig Oxford Branch and their colleagues at Oxford University is being tested in this clinical trial to evaluate the benefit it may bring to patients with NSCLC and potentially other cancer patients as well,” added Jonathan Skipper, Executive Vice President for Technology Development, Ludwig Institute for Cancer ResearchCancer Research.
About Cancer Research UK’s Centre for Drug Development
CancerCancer Research UK has an impressive record of developing novel treatments for cancer. The Cancer Research UK Centre for Drug Development has been pioneering the development of new cancer treatments for 25 years, taking over 140 potential new anti-cancer agents into clinical trials in patients. It currently has a portfolio of 21 new anti-cancer agents in preclinical
development, Phase I or early Phase II clinical trials. Six of these new agents have made it to market including temozolomide for brain cancer, abiraterone for prostate cancer and rucaparib for ovarian cancer. Two other drugs are in late development Phase III trials.
