History has been made, with every child in the first-ever Progeria clinical drug trial showing improvement in one or more areas of their condition, proving that the FTI drug lonafarnib is the first known, effective treatment for children with Progeria.

|Megan and Meghan were the first two children to enroll in the trial. The two girls met in Boston every four months for two years, for testing, to receive new drug supply, and to play together! Here they are in December 2008, on a break from tests at Boston Children’s’ Hospital.|
The results of the first-ever clinical drug trial for children with Progeria are in and it’s official! Lonafarnib, a type of farnesyltransferase inhibitor (FTI) originally developed to treat cancer, has proven effective for Progeria. Every child showing improvement in one or more of four ways: gaining additional weight, better hearing, improved bone structure and/or, most importantly, increased flexibility of blood vessels. Results of the study, which was funded and coordinated by The Progeria Research Foundation, were published September 24, 2012 in Proceedings of the National Academy of Sciences.

Results Yield Improvements in All
Twenty-eight children from sixteen countries participated in the 2 ½ year drug trial, representing 75 percent of known Progeria cases worldwide at the time the trial began. The children traveled to Boston every four months to receive comprehensive medical testing and study medications through Boston Children’s Hospital’s Clinical and Translational Study Unit. All received oral lonafarnib, an FTI supplied by Merck & Co., twice-a-day for two years, under the supervision of clinical trial chair Mark Kieran, M.D., Ph.D., Director of Pediatric Medical Neuro-oncology at the Dana-Farber / Children’s Hospital Cancer Center, and co-chairs Dr. Monica Kleinman and Dr. Leslie Gordon.

Rate of weight gain was the primary outcome measure, because children with Progeria experience severe failure to thrive, with a very slow linear rate of weight gain over time. The researchers examined many other areas of the body, including arterial stiffness (a predictor of heart attack and stroke), bone rigidity (an indicator of bone strength) and hearing. “When we started this clinical trial we had no idea whether any aspect of Progeria would be reversible, because no one had ever conducted a clinical treatment trial for Progeria before. We discovered that, among other things, the major blood vessels can actually improve. This was a breakthrough discovery for the children, since accelerated cardiovascular disease is the cause of death in Progeria. Though there is no way to know whether we have delayed strokes, heart attacks, or increased longevity within just a 2-year treatment period, these positive results compel us to continue pushing for new treatments until we accomplish what we set out to do in 1999. We want children with Progeria to live until they’re 80 and beyond. We want them to live full, healthy lives,” said Dr. Gordon, PRF’s Medical Director and first author of the treatment discovery paper.
Record Pace of Progress
The treatment discovery comes less than a decade after PRF and now National Institutes of Health Director Dr. Francis Collins joined forces to identify the cause of Progeria – an unheard of timeline in the world of medical research! But for PRF and children with Progeria, who live to an average age of just 13 years, such speed is vital to win this race against time.
“PRF is a good example of an organization
successfully enabling translational research, moving from gene discovery to
clinical treatment at an unprecedented pace,” said Dr. Kieran. “From 1999, when
the organization was founded, to today, PRF has identified the genetic mutation
that causes the disease, funded preclinical research, completed this trial,
initiated a second trial, and is currently working with our team at Boston
Children’s Hospital to plan yet another trial with drugs that, like FTIs, have
shown exciting results in Progeria cells and animal models. That’s an awesome
track record of accomplishment.”

You finished the 1st Progeria Trial – You’re A SUPERSTAR!”
How Did We Get to This Wonderful
Following the 2003 discovery of the gene mutation that causes Progeria, PRF-funded researchers identified FTIs as a potential drug treatment. The Progeria-causing mutation leads to the production of the protein progerin, which damages cell function. Part of progerin’s toxic effect on the body is caused by a molecule called a “farnesyl group,” which attaches to the progerin protein and helps it damage the body’s cells. FTIs act by blocking the attachment of the farnesyl group onto progerin, reducing the harm progerin causes.

Progeria Linked to Normal Aging
Research shows that the Progeria-causing protein progerin is also produced in the general population and increases with age. Researchers plan to continue exploring the effect of FTIs, which may help scientists learn more about the cardiovascular disease that affects millions, as well as the normal aging process that affects us all.
"Connecting this rare disease and normal aging is bearing fruit in an important way...valuable biological insights are gained by studying rare disorders such as Progeria. Our sense from the start was that Progeria had a lot to teach us about the normal aging process."

Help Us Find All Children With
Progeria so They, Too, Can Benefit From Our Work
Researchers believe that at any given time, there are 200-250 children living with Progeria. To identify unknown children, PRF launched the “Find the Other 150” campaign in October 2009, and as of September 2012, we know of 96 children living in 35 countries- an 83% increase!! You can help find more so they can benefit from the unique treatment and care that PRF provides. These new children may be eligible for future clinical trials, so please go to www.findtheother150 to find out how you can help make that happen.

Thank you ALL - We Couldn’t Have Done it Without You!
One of the main reasons we achieved breakthrough results in this first trial is because of the tremendous supporters who provided funding and other support, helping to get us one step closer to achieving our ultimate goal – a cure for Progeria.
