In a special two-part episode of TSC Now, host Dan Klein recaps the 2022 World TSC Conference, which was held in Dallas, Texas July 28-31, 2022. In part one Dan talks to two inspiring and visionary leaders in the tuberous sclerosis complex (TSC) community.

On Thursday, July 28, during the opening of the 2022 World TSC Conference in Dallas, the Ramesh and Kalpana Bhatia Family Foundation announced a new collaboration with the TSC Alliance, working together to uncover biomarkers, test new treatments and connect researchers with families to better address TSC-associated neuropsychiatric disorders (TAND), which impact nearly everyone living with tuberous sclerosis complex (TSC). The $2.5 million foundational gift is the largest single donation in the TSC Alliance’s history.

Dan first chats with Anita Bhatia, Executive Director of the Ramesh and Kalpana Bhatia Family Foundation, who announced the transformational investment to the TSC community at the conference (02:25). They discuss what it was like to announce the partnership in Dallas, what motivates her family’s generosity and how she hopes this investment will accelerate research on TSC-associated neuropsychiatric disorders (TAND) to develop new treatments and educate physicians and individuals affected by TSC so they can be better advocate for high quality care.

This new funding will create “Anya’s Accelerator,” which will focus on furthering TAND translational research. TAND includes a wide range of cognitive, behavioral and psychiatric challenges linked to the disease’s effect on brain function. The three-year “Anya’s Accelerator” research program will focus on three major goals:

  1. Developing quantifiable patient-reported outcomes for the most impactful aspects of TAND utilizing the combined expertise of individuals and families living with TSC and clinical researchers;
  2. Identifying biomarkers and predictors of specific aspects of TAND through collaborative and inclusive analysis of existing samples and data; and
  3. Improving the translatability of and testing candidate drugs in TAND-relevant animal models by incorporating biomarkers or predictors relevant to those identified in humans.

Next, Dan catches up with Pete Crino, MD, PhD, Chair of the TSC Alliance Board of Directors and the Clinic Director at the TSC Center of Excellence at the University of Maryland Medical Center (21:11). They talk about how conferences like the World TSC Conference are conduits for both the community to form new connections and get more involved in the organization, but also for researchers and clinicians to foster new collaborations and explore new avenues of research. Dr. Crino also shares why the TSC community is a vital partner in advancing TSC research and how with the support of the community and a dedicated corps of researchers and clinicians, and the infrastructure developed by the TSC community to support research, a cure for TSC is within reach.

If you weren’t able to join us in Dallas at the World TSC Conference, conference session recordings will be made available on our YouTube channel in early 2023.

In a very special early episode of TSC Now, host Dan Klein recognizes International #EpilepsyDay and the kickoff of the second annual Seizure Action Plan Awareness Week. In November 2020, a collaboration of three non-profit organizations, the TSC Alliance, Dravet Syndrome Foundation and Lennox-Gastaut Syndrome (LGS) Foundation, launched the Seizure Action Plan (SAP) Coalition to educate people with epilepsy, their caregivers and healthcare professionals about seizure emergency rescue protocols and the importance of personalized seizure action plans.  As part of this effort the group is recognizing Seizure Action Plan Awareness Week (#SAPAW2022) to coincide with International Epilepsy Awareness Day on February 14.

This month’s episode is sponsored by Noema Pharma and explores their clinical trial to treat seizures common in TSC. A Swiss biotech company, Noema, is investigating a novel substance which has shown some positive effects in laboratory models related to tuberous sclerosis complex (TSC). The substance is called basimglurant, and it affects the activity of glutamate, an important molecule used by many neurons to communicate with other neurons in the brain, by acting on a receptor for glutamate called mGluR5. The company is setting up clinical trials to test whether the effect seen in the laboratory may also be seen in people.

First, to learn more about basimglurant and preclinical experiments underpinning the upcoming clinical trial, Dan spoke to Ype Elgersma, Professor of Molecular Neuroscience, Head of Research in the Department of Clinical Genetics, and Director of the ENCORE Expertise Center for Neurodevelopment Disorders at the Erasmus Medical Center In The Netherlands; and John Kemp, Former Chief Scientific Officer at Noema (02:28). They share what metabotropic glutamate receptor 5, or mGluR5, is and how increased activity at mGluR5 may lead to epilepsy; how negative modulators of this overactivity may be used as a treatment for epilepsy in TSC, and how Dr. Mustafa Sahin of Harvard Medical School tested this hypothesis in TSC mouse models. Findings from this study was published in 2018 in Neuropsychopharmacology. 

Next, Dan spoke to Ali Mostajelean, MD, Associate Professor of Neurology, Director of the Epilepsy Service and Tuberous Sclerosis Clinic at UCSF Benioff Children’s Hospital; and George Garibaldi, Chief Medical Officer at Noema (07:55). They shared how Noema is using the findings in animal models as justification for a clinical trial and share how clinical studies using basimglurant for depression and Fragile X showed that the compound was safe in humans, albeit not as effective as researchers thought it would be in those disease states.

Finally, Dan spoke with Renata Lazarova, VP of Development, Pediatric Programs at Noema, and Steve Roberds, PhD, Chief Scientific Officer of the TSC Alliance (10:55), to learn what the clinical trial looks like, who can enroll, how Noema will determine whether the drug is efficacious and safe, and where people can find more information. Steve also talked about our partnership with Noema and how they worked with the TSC Alliance early on to solicit feedback from the TSC community and design a trial that both meets the needs of those with TSC and considers the quality of life of those participating.

Noema’s clinical study with their negative modulator of mGluR5 is currently participants across the US, Russia, Ukraine, Israel and Australia.
