Press Release: Tetra Discovery Partners Initiates Phase 2 Trial of BPN14770 in Fragile X Syndrome

Tetra Discovery Partners today announced the initiation of a Phase 2 study of BPN14770 as a potential treatment for Fragile X Syndrome, the most common genetic form of autism. A selective small molecule inhibitor of the phosphodiesterase type-4D (PDE4D) subtype, BPN14770 has shown the ability to improve the quality of connections between neurons and to improve multiple behavioral outcomes in the Fragile X mouse model.

Aripiprazole as a Treatment for Fragile X Syndrome

Aripiprazole as a Treatment for Fragile X Syndrome

Many medications are used to help people with Fragile X cope. But few clinical trials have been done on these drugs. Years ago FRAXA funded Dr. Craig Erickson to run a trial of aripiprazole (aka Abilify). FRAXA guest writer Hannah Miles recently caught up with Dr. Erickson to learn the results of the trial.

Now Recruiting: Clinical Study of EEG for Young Boys at Boston Children’s Hospital

Now Recruiting: Clinical Study of EEG for Young Boys at Boston Children’s Hospital

Dr. Carol Wilkinson, MD PhD, and Dr. Charles Nelson, PhD, at the Labs of Cognitive Neuroscience at Boston Children’s Hospital are recruiting young boys with Fragile X syndrome (FXS) to participate in a study investigating how differences in brain activity affect learning, language, and behavior in FXS. If we can determine what distinguishes one brain from another, and if a drug works with a particular neural marker or set of neural markers, this would permit matching drugs based on objective biological markers, a personalized medicine, rather than defaulting to the current method of trial and error.

Double Down: Fragile X Clinical Trial Combines Two Available Drugs

Double Down: Fragile X Clinical Trial Combines Two Available Drugs
Jean-Francois Lepage, PhD, and Francois Corbin, MD, PhD, with MRI machine If all the science world’s a stage, Fragile X researchers are more than merely players. They are center stage. So believes Francois Corbin, MD, PhD, professor, Université de Sherbrooke, Canada, who directs the university’s Fragile X Clinic. Corbin, who has received more than $100,000 in FRAXA support since 2012, is leading a pilot randomized Phase II trial, exploring the tolerability and the synergistic effect of a combined therapy. They will combine minocycline, which is often used to treat acne, and lovastatin, which is used to lower cholesterol. Both drugs target specific alterations in the brain of Fragile X patients that would potentially have a combined powerful effect on their behavior. “To my knowledge, this is the first time we have a clinical trial with two different drugs combined to act on two different targets,” Corbin said. “The combined actionRead more

Neuren’s Tofinetide Successful in Phase 2 Clinical Trial in Fragile X

Neuren’s Tofinetide Successful in Phase 2 Clinical Trial in Fragile X
One of the outcome measures - the new Fragile X Syndrome Rating Scale - showing positive results. Blue: placebo; Yellow: low-dose trofinetide; Green: high-dose trofinetide We are pleased to share great news adapted from Neuren’s press release: Neuren’s phase 2 trial has successfully established proof of concept and provides a strong rationale for Neuren to move forward with developing trofinetide for Fragile X syndrome. In this initial small trial with a relatively short treatment period, trofinetide was very well tolerated, with the high dose (70 mg/kg twice daily) demonstrating a consistent pattern of clinical improvement, observed in both clinician and caregiver assessments. After only 28 days of treatment, improvements were seen across core symptoms of Fragile X syndrome, including higher sensory tolerance, reduced anxiety, better self-regulation and more social engagement. No serious adverse events were reported. Positive Results in Fragile X Syndrome and Rett Syndrome Beneficial effects of trofinetide have now been observed in both FragileRead more

Neuren’s NNZ-2566 Shows Clinical Benefit in Rett Syndrome Trial

Neuren’s NNZ-2566 Shows Clinical Benefit in Rett Syndrome Trial
Promising Results in Phase 2 Clinical Trial This isn’t a Fragile X trial, but the Neuren compound, NNZ-2566, that is in trials now for Fragile X has shown significant positive effects in a Phase 2 trial for Rett syndrome. The results of the trial are interesting, in that improvement was seen a Rett syndrome-specific rating scale compared to placebo, and there was also improvement noted on the CGI-I (Clinical Global Impression of Improvement) and Caregiver Top 3 Concerns. However, there was no effect seen on ABC scores (Aberrant Behavior Checklist) compared to placebo. Many in the Fragile X field have noted the inadequacies of the ABC; indeed, it was never designed or intended to be an outcome measure for clinical trials. In this case, a Rett-specific rating scale called the Motor-Behavior Assessment (MBA) showed a statistically significant and clinically meaningful treatment effect at the highest dose of the Neuren compoundRead more

Why Did Fragile X Clinical Trials of mGluR Antagonists Fail?

Why Did Fragile X Clinical Trials of mGluR Antagonists Fail?
Drug Tolerance and Dose Range Problems May Have Been the CulpritsAndy Tranfaglia and his dad, Mike Tranfaglia In my opinion, the Fragile X clinical trials of AFQ056 sponsored by Novartis failed because of a dose range that was inadequate for Fragile X, and because of the unexpected development of tolerance. Dosage problems are relatively easy to correct, but tolerance to the degree we observed may be a kind of fatal flaw, at least if we're talking about mGluR5 antagonists.  The mGluR Theory of Fragile X is still probably correct; it's just that no one (least of all Novartis) expected tolerance to this drug -- indeed, I'm not sure they would agree that's what happened. I think we saw a much better response than most people because our son, Andy, was also on minocycline, effectively augmenting the response, and perhaps delaying the development of tolerance.  This may be a clue to understanding the mechanism of tolerance,Read more

Fragile X Clinical Trial: Novartis Trial Results Are In, and They’re Not Pretty

AFQ056 Fragile X Clinical Trial showed Negative Results This year's Gordon Conference just finished, and Novartis presented their results for the first time (though advisors and advocates had been given a private peak months ago.) To say that the trial results for AFQ056 were disappointing would be the understatement of the century! While the company has already announced that the adult and adolescent trials failed to meet their pre-designated endpoints, the numbers looked really bad. This wasn't a case of the drug working, but placebo effects leading to an outcome that wasn't statistically significant; in this case, the effect of the drug was statistically significant, but in the wrong direction! So, what went wrong? The evidence for using mGluR5 antagonists in Fragile X was really strong going into these trials---in fact, about as good as it ever gets. The drug itself was an advanced compound that had been studied extensively.Read more

Clinical Trials FAQ ← Frequently Asked Questions

Question: How Do Families Decide Which Trial is Best for Them? Answer: Each of the trials has different requirements for joining, so many – if not most – people will only be eligible for one trial after screening. The best way to approach this is to call the clinic contact closest to your area and discuss this with him/her. Age, weight, current medications, behavior, and IQ are all factors. When will the Trials be Finished? It all depends on enrollment. Trials need to have a certain number of people (a number determined before the trial starts) complete the trial before they can analyze the data and present results to the FDA. It all depends on how many people sign up to participate. Is There Assistance for Travel? Many trials provide financial assistance for travel expenses. The amount depends on how far you have to travel. Please check with the coordinatorRead more
