Jennie Landsman’s 2-year-old son, Benny has always been a
laid back little guy.
“He’s a very chill dude,” says Jennie, 34, who owns a yoga
and martial arts studio in Brooklyn, New York, where she lives with her family.
He’s so mellow that when he struggled to reach milestones at
6 months that other babies easily met, Jennie figured this was just part of his
laid-back personality since he was as social as can be.
“He understood peek-a-boo,” she says. “He would respond with
a big smile if you said hello. He just wasn’t sitting up and he wasn’t reaching
very well for things.”
But with Benny still unable to sit up, support his head or
roll over at 7 and 8 months, Jennie took him to several neurologists before
learning in August 2017, that he – and his new baby brother, Josh, who was born
a month earlier, suffered from Canavan disease — a rare, progressive and fatal
genetic neurological disorder. Worst of
all, the debilitating disorder, which leads to an inability to walk, talk and
even swallow, leaves affected children with a lifespan of just 5 to 10 years
old.
“Broken is not even enough of a description,” says Jennie
about how she felt when a geneticist delivered the horrific news to her and her
husband, Gary Landsman, 44.
“It was really dark, really scary, and there were lots of
tears,” says Gary, who got the news not long after he opened a new business,
Taste Wine Co. in Manhattan’s East Village.
Told by doctors that nothing could be done for the boys
except to “go home and love them,” Jennie and Gary at first sank into a deep
depression, terrified about the uncertain future ahead.
“Every time I held either one of my babies, every time I
rocked them to sleep, I couldn’t stop thinking, ‘How many more times will I
hold my baby?’ ” says Jennie. “‘How many more times will I hold their hands?'”
Weeks later, Jennie realized that she and Gary needed to
take action themselves. Searching the Internet and asking her growing network
of contacts in the Canavan world about treatment options that could somehow
help her babies, she hit the jackpot when she found a promising gene therapy
that will likely halt – and even reverse the disease’s most damaging symptoms.
The cost? A whopping minimum $1.2 million to allow renowned
neuroscientist Dr. Paola Leone, director of the Cell and Gene Therapy Center at
Rowan University’s School of Osteopathic Medicine in New Jersey and her team to
finish developing the cutting-edge therapy. “The hope is that they will lead
full, functional lives,” says Leone, whose gene therapy has already proven
successful in mice.
In the potentially life-saving clinical trial, Benny, Josh
and other children will undergo a surgical procedure to have a
genetically-engineered virus injected into their brains to help them produce
normal white matter which they need to regain motor function.
“We have an expectation that the therapy will make a real
difference in the lives of these kids,” says renowned neurologist Dr.
Christopher Janson of the University of Illinois at Chicago who will direct the
team performing the surgeries.
Their state-of-the-art research can also help find a cure
for other diseases including ALS, Alzheimer’s and Parkinson’s.
Wanting to do everything they could to give their boys — and
other children suffering from Canavan — any chance at life they could, Jennie
and Gary set out against all odds to raise the money for the therapy and the
clinical trial.
“We had no idea how we were going to do this,” she
says.“When you have kids you know you would do anything for (them.)”
So they simply asked for help — in a humble, touching — and
heartbreaking video they filmed in their living room – sitting on their couch
and holding their boys on their laps – that was shot by their wedding
videographer, which they posted on the GoFundMe campaign – called Save Benny
and Josh – that they launched in November.
Over the next six months, to come close to their goal by
raising $1.15 million with the help of family, friends and strangers alike.
“We are so grateful,” says Jennie, who calls the generosity
they were shown a miracle.
“I put up a link and people showed up. It’s unbelievable.”
Besides hundreds of people with huge hearts, she says, “God
played a huge role in this.”
Even her 8-year-old son Michael Heiney, from her first
marriage, stepped up, reading science fiction books “to help find a cure,” she
says.
The family’s fundraising is still not done, though.
Additional costs that have come up – including specialized
MRIs the boys will need, plasma, and further studies and testing the FDA is now
requesting, have driven the price way up.
To meet these mounting costs, Jennie and Gary have raised
their GoFundMe goal to $1.5 million – for now – so that they can cover these
costs and help pay for surgeries and MRIs for the other children in the trial.
(The money raised by their GoFundMe has already covered the costs for other
children to participate in the trial and receive the treatments.)
“We have been given so much that we want to give back, too,”
she says.
Adds Gary: “This is part of an ongoing mission that Jennie
and I are going to have for the rest of our lives.”

ReplyDeleteAbstract
Diseases of the central nervous system (CNS) have traditionally been the most difficult to treat by traditional pharmacological methods, due mostly to the blood-brain barrier and the difficulties associated with repeated drug administration targeting the CNS. Viral vector gene transfer represents a way to permanently provide a therapeutic protein within the nervous system after a single administration, whether this be a gene replacement strategy for an inherited disorder or a disease-modifying protein for a disease such as Parkinson's. Gene therapy approaches for CNS disorders has evolved considerably over the last two decades. Although a breakthrough treatment has remained elusive, current strategies are now considerably safer and potentially much more effective. This chapter will explore the past, current, and future status of CNS gene therapy, focusing on clinical trials utilizing adeno-associated virus and lentiviral vectors.

ReplyDeleteAbstract
Canavan disease, a leukodystrophy caused by loss-of-function ASPA mutations, is characterized by brain dysmyelination, vacuolation, and astrogliosis ("spongiform leukodystrophy"). ASPA encodes aspartoacylase, an oligodendroglial enzyme that cleaves the abundant brain amino acid N-acetyl-L-aspartate (NAA) to L-aspartate and acetate. Aspartoacylase deficiency results in a 50% or greater elevation in brain NAA concentration ([NAAB]). Prior studies showed that homozygous constitutive knockout of Nat8l, the gene encoding the neuronal NAA synthesizing enzyme N-acetyltransferase 8-like, prevents aspartoacylase-deficient mice from developing spongiform leukodystrophy. We now report that brain Nat8l knockdown elicited by intracerebroventricular/intracisternal administration of an adeno-associated viral vector carrying a short hairpin Nat8l inhibitory RNA to neonatal aspartoacylase-deficient AspaNur7/Nur7 mice lowers [NAAB] and suppresses development of spongiform leukodystrophy.
