Jack with State Senators Don Harmon and Kwame Raoul at the Ann and Robert H Lurie Children’s Hospital of Chicago on Friday to celebrate the new KCNQ2 Awareness week in Illinois.

Friday night, March 2, 2018, at the Ann and Robert H. Lurie Children’s Hospital of Chicago saw a memorable gathering of doctors, lawmakers, scientists, parents, siblings and children affected by KCNQ2-related epilepsy.

Spreading KCNQ2 awareness is important to me
                                       –Rick Terven

On that day, the State of Illinois gave the KCNQ2 community a sense of hope with the passing of a resolution that designates the first week of March as KCNQ2 Awareness Week. This recognition is the latest exciting step that adds to our efforts to bring attention and resources to the fight against KCNQ2-related epilepsy.
“Spreading KCNQ2 awareness is important to me, because there are ways to improve the outcomes for many children with neonatal onset epilepsy disorders,” says Rick Terven, dad of one-year-old Amelia who has KCNQ2-related epilepsy.
“We can help children in those critical first few months to get diagnosed and properly treated much quicker than is currently happening in many instances.” It was through the efforts of Rick and Michelle Terven that this resolution was passed. A huge thanks to them!
All had the chance to speak with the doctors and scientists who are constantly pushing forward in this field. The families visited with each other and the siblings played together. At the end of the day, we all had a little more hope than we did before.


Pediatric epileptologist Dr. John Millichap, who was in attendance at Friday’s festivities, says, “Public awareness of KCNQ2 encephalopathy is important for many reasons.  I would like to emphasize that physicians caring for young children with unexplained seizures should consider genetic testing early since a positive result can lead to specific options for treatment and prevention of sequelae.”


What a fantastic event for the families of these beautiful children. What started out as a few isolated cases has grown into a global crusade to help these kids win this war.

Announcing the Sophie Award for Young KCNQ2 Investigators

This is a story about faith in the future.

Sophie was born in Arkansas to parents Sasha and Colten on January 4th, 2015. When Sophie was diagnosed with KCNQ2 at 4 weeks old, her parents did what most parents faced with this diagnosis do: whatever they can to help their children.

Sadly, little Sophie, who had further medical complications, died at just 13 months old. For Sasha and Colten, that desire to do whatever they could to help Sophie turned into a desire to help other KCNQ2 children. They made a tough decision and donated her brain to science. This donation will help in the study of epilepsy and KCNQ2.

So to honor Sophie and her parents’ tremendous gift, The Jack Pribaz Foundation is establishing a new award for KCNQ2 research. We are calling it the Sophie Award for Young KCNQ2 Investigators.

This is an award that looks bravely forward, like Sasha and Colten have. It is a grant in the amount of $15,000, designed to support and encourage research of KCNQ2-related epilepsy.

We are thrilled to announce the first Sophie Award winner today at the 70th Annual Meeting of the American Epilepsy Society in Houston, Texas.  The recipient is Dr. John Millichap, attending physician at the Neurology and Epilepsy Center at the Ann and Robert H. Lurie Children’s Hospital in Chicago and Assistant Professor of Pediatrics and Neurology, Northwestern University Feinberg School of Medicine. We chose Dr. Millichap for his outstanding dedication to bridging bench science and clinical application and for his contributions to the medical literature. His work is advancing understanding of KCNQ2-related epilepsy into the next generation of scientists and clinicians.


Dr. John Millichap

“I’m so proud to receive this award and to be a part of KCNQ2-related epilepsy research,” said Dr. Millichap. “The spirit of collaboration I’ve found on an international scale among both researchers and families is uncommon and powerful. Together we have come a long way in a relatively short time, but there is a lot of work ahead of us,” he said. “Receiving the Sophie Award is exciting but also humbling, because at the heart of our efforts are children and families who desperately need science to catch up with their conditions.”

We are very passionate about this prize because it is a special opportunity to support KCNQ2 research and also to recognize the important partnership that KCNQ2 families have with researchers. That’s what Sophie’s gift was all about.

Look into the future with us. Gifts made to the Sophie Award for Young KCNQ2 Investigators will go to sponsor scientists, grad students, doctoral candidates, and young professors of the future in Sophie’s memory.

We sincerely thank Sasha and Colten for their dedication to the KCNQ2 cause. And we congratulate them, too– they had a new baby boy this summer! They give us so much hope!


Novel KCNQ2 activators as promising drugs for epilepsy treatment

You have heard of Potiga, a drug used to treat KCNQ2-related epilepsy. But what about new drugs in development like SF0034 or RL648_81?  KCNQ2 Perspectives asked renowned pharmacologist and Jack Pribaz Foundation scientific adviser Dr. Maurizio Taglialatela to provide an overview of potassium channel openers. We are grateful for his help in understanding these drugs and offering a glimpse of what promising new treatments may lie on the horizon.

Precision medicine is an emerging approach for disease treatment and prevention that takes into account individual variability in genes, environment, and lifestyle. For genetic diseases such as most epileptic encephalopathies (EE), precision medicine aims to provide individually tailored treatments based the underlying genetic cause.

For KCNQ2-EE, molecular diagnosis may influence the choice of antiepileptic drugs. In fact, most of the genetic variants identified in KCNQ2-EE, when studied in vitro by conventional electrophysiological methods, cause a decrease in KCNQ2 channel function (loss-of-function or LOF variants). An antiepileptic drug which enhances KCNQ2 channel function may represent a novel therapeutic approach in those patients carrying LOF KCNQ2 variants.


Among currently available antiepileptic drugs, retigabine or ezogabine (trade name Trobalt or Potiga) is the only one whose clinical efficacy is related to this specific mechanism of action. Unfortunately, although retigabine is approved for use in adults with epilepsy, its use in infants and children is very limited. Moreover, post-marketing studies revealed the occurrence of side effects with retigabine, including a blue discoloration of the skin and mucosae and pigment deposition in the retina. It is yet unknown whether this latter effect, which appears as a consequence of the drug’s photodegradation and oxidation upon exposure to UV radiations, affects vision in the long term. Another side effect occurring with retigabine is urinary retention, possibly a consequence of the poor selectivity of retigabine/ezogabine for KCNQ2 channels over channels of the same subfamily (particularly KCNQ4), which do not appear to play a significant role in epilepsy, but which are involved in the control of bladder smooth muscle contractility.


To improve retigabine safety and selectivity, in the last few years, several research groups have synthesized and characterized the pharmacological properties of a large number of retigabine analogs (as well as other KCNQ2 activators structurally unrelated to retigabine). Among the novel molecules resulting from these efforts is SF0034, a compound which, when compared to retigabine, is more potent and KCNQ2-selective (Kalappa et al., 2015). Preclinical studies in animals also revealed that SF0034 exhibits a more potent anticonvulsant activity and less toxicity than retigabine. In addition, SF0034 was significantly less active on KCNQ4 channels, leading to the suggestion that, in comparison with retigabine, side effects associated with activation of this channel subtype may be less likely to occur with SF0034. SF0034 seems to be more chemically stable and does not produce blue metabolites, suggesting that it may be a useful clinical candidate for epilepsy and other diseases linked to KCNQ2 hypofunction (such as tinnitus).


Even more recently, another analogue of retigabine, named RL648_81, has been reported in the literature (Kumar et al., 2016); this compound is 3 times more potent than SF0034 and 15 times more potent than retigabine in activating KCNQ2 channels in in vitro electrophysiological studies. The same studies also revealed that RL648_81 is also more selective than retigabine for activation of KCNQ2 channel over channels formed by other KCNQ subtypes. However, no pharmacokinetic data on drug absorption, metabolism, distribution and elimination from the organism is yet available for RL648_81 (either in experimental animals or in humans), and no antiepileptic efficacy has been proven for this drug in preclinical or clinical studies. Nonetheless, it seems likely that this more potent, selective and chemically stable KCNQ2/3 activator may be yet another attractive candidate for treating or preventing hyperexcitability disorders, overcoming some of the undesirable side effects associated with retigabine.

In conclusion, based on the discovery that KCNQ2 channels play critical roles in epilepsy pathogenesis and treatment, both academic and industry efforts are being actively pursued to develop novel KCNQ2 activators. Whether these novel drugs will prove useful as targeted therapies to improve neonatal seizures and developmental outcome in neonates with KCNQ2-EE remains to be demonstrated in the years to come.
