August 09, 2021, PLANO, Texas--(BUSINESS WIRE)--Reata Pharmaceuticals, Inc. (Nasdaq: RETA) (“Reata,” the “Company,” “our,” “us,” or “we”), a clinical-stage biopharmaceutical company, today announced financial results for the quarter ended June 30, 2021, and provided an update on the Company’s business operations and clinical development programs. 

Omaveloxolone in Patients with Friedreich’s Ataxia (“FA”). Based on a communication received from the U.S. Food and Drug Administration (“FDA”) regarding omaveloxolone for the treatment of FA, we withdrew our request for a Type C meeting and requested a pre-NDA meeting with the FDA. The pre-NDA meeting request has been granted, a pre-NDA meeting has been scheduled during the third quarter of this year, and we have submitted briefing materials for the meeting. We recently received a communication from the FDA requesting the estimated date of our New Drug Application (“NDA”) for its planning purposes. We plan to submit the NDA during the first quarter of 2022.

Design Therapeutics Reports GeneTAC™ Portfolio Progress and Second Quarter 2021 Results

CARLSBAD, Calif., Aug. 09, 2021 (GLOBE NEWSWIRE) -- Design Therapeutics, Inc. (Nasdaq: DSGN), a biotechnology company developing treatments for degenerative genetic disorders, today reported recent progress with its portfolio of novel small molecule gene targeted chimeras (GeneTACsTM), as well as business highlights and second quarter 2021 financial results. New Data from IND-enabling Studies with GeneTAC Product Candidate for Friedreich Ataxia (FA) Support Initiation of Clinical Trial in First Half of 2022: Data from IND-enabling studies in rodents and non-human primates showed that multidose systemic administration of the company’s FA GeneTAC was well tolerated and achieved higher concentrations in the CNS (cerebrum, cerebellum, brainstem and spinal cord), heart, and skeletal muscle than needed to restore frataxin (FXN) gene expression. In addition, the company observed that exposure to low nanomolar (nM) concentrations of its FA GeneTAC in neurons and cardiomyocytes derived from FA patient stem cells in in vitro experiments led to robust and durable increases in FXN mRNA, as well as an increase in endogenous protein reaching levels comparable to unaffected individuals.

Diagnostic and Prognostic Value of Cardiovascular Magnetic Resonance in Neuromuscular Cardiomyopathies

Almogheer B, Antonopoulos AS, Azzu A, Al Mohdar S, Vlachopoulos C, Pantazis A, Mohiaddin RH.; Pediatr Cardiol. 2021 Aug 3. doi: 10.1007/s00246-021-02686-y. Epub ahead of print. PMID: 34342696. 

We present data from a unique cohort of NMD patients and provide evidence on the incidence, patterns, and the prognostic value of LGE in NMD-related cardiomyopathy. LGE is variably present in NMD subtypes and correlates with LV remodelling, dysfunction, and clinical outcomes in patients with NMD. The study included retrospective analysis of a cohort of 111 patients with various forms of NMD; mitochondrial: n = 14, Friedreich's ataxia (FA): n = 27, myotonic dystrophy: n = 27, Becker/Duchenne's muscular dystrophy (BMD/DMD): n = 15, Duchenne's carriers: n = 6, other: n = 22.

Un bri d’esperança

Dissabte, 7 agost 2021, El Punt Avui.

L’atàxia de Friedreich provoca problemes de coordinació, força muscular i cor i escurça l’esperança de vida fins als 40 anys. L’objectiu del fàrmac, que ja està en fase clínica, és aturar la progressió d’aquestes malalties o, almenys, alentir-la. “No és el mateix treballar desenvolupant medicaments per a malalties on hi ha moltes opcions terapèutiques que aquí, on si no te’n surts els malalts no tenen res més. La pressió és molt alta però també la motivació”, reflexiona el CEO de Minoryx.

Digital endpoints for self-administered home-based functional assessment in pediatric Friedreich’s ataxia

Arne Mueller, Elaine Paterson, Avery McIntosh, Jens Praestgaard, Mary Bylo, Holger Hoefling, McKenzie Wells, David R. Lynch, Christian Rummey, Michelle L. Krishnan, Meredith Schultz, C. J. Malanga; Ann Clin Transl Neurol. doi:10.1002/acn3.51438

Deploying digital endpoints in home settings is feasible in this population, results in meaningful and robust data collection, and may allow for frequent sampling over longer periods of time to track disease progression. Care must be taken when training participants, and investigators should consider the complexity of the tasks and equipment used.

The Role of Voltage-Dependent Anion Channel in Mitochondrial Dysfunction and Human Disease

Varughese J, Buchanan S, Pitt A., Cells. 2021 Jul;10(7). PMCID: PMC8305817 doi:10.3390/cells10071737

The voltage-dependent anion channel (VDAC) is a β-barrel membrane protein located in the outer mitochondrial membrane (OMM). VDAC has two conductance states: an open anion selective state, and a closed and slightly cation-selective state. VDAC conductance states play major roles in regulating permeability of ATP/ADP, regulation of calcium homeostasis, calcium flux within ER-mitochondria contact sites, and apoptotic signaling events. Three reported structures of VDAC provide information on the VDAC open state via X-ray crystallography and nuclear magnetic resonance (NMR). Together, these structures provide insight on how VDAC aids metabolite transport. The interaction partners of VDAC, together with the permeability of the pore, affect the molecular pathology of diseases including Parkinson’s disease (PD), Friedreich’s ataxia (FA), lupus, and cancer.

Determining the Validity of Conducting Rating Scales in Friedreich Ataxia through Video

Tai, G., Corben, L.A., Woodcock, I.R., Yiu, E.M. and Delatycki, M.B. (2021); Mov Disord Clin Pract, 8: 688-693. doi:10.1002/mdc3.13204 

Excellent test–retest reliability was demonstrated in the majority of the mFARS sections, and in the total mFARS and SARA scores, suggesting that video is a valid method of conducting these scales. This method enables inclusion of participants who are unable to travel to study sites. A larger cohort will be required to further validate the use of video mFARS and SARA for future studies.

Polyuria and Acute Hyperglycemia Secondary to New-Onset Diabetes in a Young Woman With Friedreich’s Ataxia

Santos J, Woloski J R, Wu N (June 29, 2021); Cureus 13(6): e16032. doi:10.7759/cureus.16032 

Diabetes is a common complication in patients with FRDA and should be routinely screened for by healthcare providers, preferably via an OGTT. Treatment of diabetes can be challenging due to neurodegenerative symptoms that may interfere with the ability to self-administer insulin. Additionally, close follow-up with cardiology is important to monitor for any signs or symptoms of cardiomyopathy, especially after the initiation of diabetes medications. Once diabetes is diagnosed, an individualized treatment plan along with efficient coordination of care is essential for successful diabetes management in patients with FRDA.

Cardiac Involvement in Movement Disorders

Rossi M, Wainsztein N, Merello M.; Mov Disord Clin Pract. 2021 Apr 7;8(5):651-668. doi: 10.1002/mdc3.13188. PMID: 34307738; PMCID: PMC8287161.

As cardiac disease is part of the phenotypic spectrum of several movement disorders, heart involvement should be carefully investigated and increased awareness of this association encouraged as it may represent a leading cause of morbidity and mortality.

Neuro-Ophthalmological Findings in Friedreich’s Ataxia

Rojas, P.; de Hoz, R.; Cadena, M.; Salobrar-García, E.; Fernández-Albarral, J.A.; López-Cuenca, I.; Elvira-Hurtado, L.; Urcelay-Segura, J.L.; Salazar, J.J.; Ramírez, J.M.; Ramírez, A.I.; J. Pers. Med. 2021, 11, 708. doi:10.3390/jpm11080708 

Although most patients with FRDA do not present with symptomatic visual impairment, 73% present with clinical neuro-ophthalmological alterations such as optic atrophy and altered eye movement, among others. This review provides a brief overview of the main aspects of FRDA and then focuses on the ocular involvement of this pathology and the possible use of retinal biomarkers.
