A father who suffered with the world’s deadliest form of brain cancer has been cleared after he underwent an experimental treatment.

Ben Trotman, 43, who was diagnosed with glioblastoma in October 2022, is now showing no signs of the disease after being administered an immunotherapy drug in a world first two years ago.

Most patients with the aggressive form of brain cancer typically die within 12-to-18 months.

Consultant medical oncologist, Dr Paul Mulholland, who is leading the new trial and treated Mr Trotman, said: ‘It is very unusual to have a clear scan with glioblastoma, especially when he didn’t have the follow-up surgery that had been planned to remove all of the tumour that was initially visible on scans.

‘We hope that the immunotherapy and follow-up treatment Ben has had will hold his tumour at bay – and it has so far, which we are delighted to see.’

Mr Trotman married his wife Emily two months after the immunotherapy treatment in 2023, and in April, his daughter Mabel was born.

The father-of-one said: ‘Getting this diagnosis was the most traumatic experience. We were grappling with the fact that Ben had gone from being apparently perfectly healthy to having months to live. 

‘Had we not met Dr Mulholland, that would have been it for us. We felt we had a lucky break in an otherwise devastating situation.’

Mr Trotman went on to have the current standard treatment of radiotherapy and chemotherapy. He also undergoes quarterly cans, which continue to return clear.

‘We obviously don’t know what the future holds but having had the immunotherapy treatment and getting these encouraging scan results has given Emily and I a bit of hope,’ he said.

‘We are focused on rebuilding the life we thought we had lost and enjoying being parents’.

The trial, from University College London Hospital’s National Hospital for Neurology and Neurosurgery, follows a previous one on the same drug which closed because of lack of recruitment. 

But Dame Siobhain McDonagh MP lead a fundraising campaign to raise more than £1million to cover the costs of the new trials after her sister, Baroness McDonagh, died from glioblastoma in 2023.

Dame Siobhain said: ‘My beloved sister Margaret was appalled to discover that there had been no advances in brain cancer treatment for decades when she was diagnosed with glioblastoma.

‘Changing this was Margaret’s final campaign and one that I have continued in her memory.

‘I am so grateful to the many people who knew and respected Margaret who have come together and helped to raise funds and campaign for this new trial that we are calling Margaret’s Trial.’

Dr Paul Mulholland said: ‘When I met Margaret she said to me ‘what can I do to support you to cure this disease?’.

‘I am incredibly grateful to her and to Siobhain whose campaigning and fundraising in her sister’s memory has led to this new clinical trial opening for patients with this most aggressive form of brain cancer that has such a poor prognosis, with most patients surviving just nine months after diagnosis.

‘The crucial element of this trial is that patients will have their immune system boosted by the drug before they have any other treatment, when they are fit and well enough to tolerate the immunotherapy.

‘We’re taking everything we have learned from previous trials into this new study and we are already planning follow-on trials.

‘My aim is to find a cure for glioblastoma.’

The National Brain Appeal is currently funding two posts in support of Dr Mulholland’s research. 

Treatment will take place at the NIHR UCLH’s Clinical Research Facility and at the National Hospital for Neurology and Neurosurgery.
