Jeans for Jerry: your chance to give him a future

We recently told you about a happy three year old child named Jerry, described by his mother Bess as having “a really beautiful and sweet nature.”

Jerry from Sale has a condition called SPG50 that Bess told us is “a type of hereditary spastic paraplegia.”

Bess and David Ong are using Jeans for Genes Day tomorrow to raise money for a gene therapy clinical trial that could very well save Jerry’s life.

“The money raised is going to a lab at the Children’s Medical Research Institute that specialises in gene therapy,” Bess said.

SPG50 is extremely rare with only 60 cases in the world. The progressive condition means Jerry will soon lose his hard-won ability to crawl and to walk as spasticity takes over his limbs. He may never speak and his brain will continue to deteriorate.

Jerry’s best hope is for research to unlock new treatments and cures, to give him and others the opportunity to live long and healthy lives.

Bess and David have launched a fundraiser Jeans for Jerry.

Due to the reimposed Covid-19 restrictions, any sort of social fundraising activity like wearing jeans at work is not currently possible. But we can still make a donation through the Jeans for Jerry web site. In fact, many have been doing that, with almost $30,000 raised so far.

Some good research is being achieved about SPG50 and other rare diseases by Dr Leszek Lisowski and his team at the Children’s Medical Research Institute in Sydney. See below the next photo if you’d like to know more.

Researchers fighting to ensure children with the rarest diseases don’t fall through the cracks

An Australian world-leading gene therapy expert believes the future of medicine is in personalised treatments for children with rare diseases who often “slip through the cracks’’.

Dr Leszek Lisowski is the Unit Head of the Translational Vectorology Research Unit and Manager of the Vector and Genome Engineering Facility at Children’s Medical Research Institute in Sydney. It is the only lab of its kind in Australia and one of the few in the world.

His work is highly technical, but his personal approach is led by the heart.

“What I’m trying to do is build individualised treatments for patients, for those children who have ultrarare conditions—this is where my heart lies.’’

It is work such as this that may help save the life of children such as three-year-old Jerry Ong, from Gippsland, in Victoria.

Jerry was born with an extremely rare condition known as SPG50 – associated hereditary spastic paraplegia – a mutation of the AP4M1 gene. The progressive condition means he will soon lose his hardwon ability to crawl and to walk as spasticity takes over his limbs. He may never speak, and his brain will continue to deteriorate.

Jerry’s parents, Bess and Dave Ong, hope gene therapy will reverse the progression and are fundraising for a clinical trial that might help save their son’s life.

“Dr Lisowski’s research focuses on gene-therapy technology, which could cure this insidious disease by halting the disease process and preventing the faulty gene from further damaging Jerry’s brain and body,” Ms Ong said.

“The research has turned up exciting results, and clinical trials are possible. But they’re expensive and health dollars are stretched, no more so than during an international pandemic. We have joined the effort to raise money to support this research. Every dollar counts.”

Dr Lisowski creates microscopic delivery vehicles, called vectors, which are key tools required for the successful applications of gene therapies. The vectors deliver gene therapeutics into patient’s cells affected by the disease. The therapy adds a working copy or replaces the faulty copy of a gene with a functional version.

Genome therapy aims to cure, not just treat, genetic disorders by correcting the mutations.

In the past, his work has been used for genetic diseases that impact the hematopoietic system or the liver, but now he is hoping to start a new project working to help young patients, such as Jerry.

“We will use a viral vector to deliver a functional copy of the SPG50 gene to the patient’s brain,’’ Dr Lisowski said. “We will make pre-clinical models, using organoids, and we are very fortunate because CMRI has the best organoid facility in Australia.’’

Organoids are mini organs that are grown in labs to test out therapies. The team at CMRI will use brain cells to test their therapy before trials can begin.

“While the knowledge and diagnostic power around genetic disease has grown exponentially, the progress in disease prevention and treatment has been slower. Gene therapy has the power to fill the gap that has formed and to bring real benefits to patients,” he said.

Gene therapies are relatively new additions to the healthcare toolbox but are already saving lives by curing previously incurable conditions.

“Infants who would otherwise have succumbed to devastating neurological disorders are now developing normally with the very real prospect of living full and healthy lives,” he said.

“This is an exciting and a very rewarding time to be a researcher in the area of gene therapy. We are hoping to be able to deliver this treatment to children within two years of starting the trials. It could even be faster.’’

While incredible work is being done around the world on truly devastating diseases, those with rarer conditions like Jerry are often forgotten.

Dr Lisowski wants to devote his work to helping families like Jerry’s.

“This condition is ultra-rare and most government or commercial funding would not go towards a condition like this; they often slip through the cracks. To help this family really aligns with my own personal values. We want to help people that aren’t being helped, to find those who are being

Children’s Medical Research Institute (CMRI) pioneered microsurgery, immunisations against lethal childhood illnesses, and care for premature babies, all of which has improved the lives of countless Australian children over the last 60 years.

Today, CMRI is an independent institute and the site of world-leading research in the areas of cancer, neurobiology, embryology, genomics and gene therapy. CMRI’s achievements are made possible by a network of devoted community supporters, as well as the iconic Jeans for Genes® campaign.

If you would like to support the work of Dr Lisowski, you can donate to a Jeans for Genes fundraising page set up by Jerry’s family to directly fund the work being done in Dr Lisowski’s lab.
