Psychologists study how application of cortisol affects exposure therapy for anxiety disorders

news-medical | April 25, 2019

Bochum-based psychologists have studied how the application of the stress hormone cortisol affects exposure therapy for anxiety disorders. The researchers knew from earlier studies that extinction learning, which constitutes the foundation of exposure therapy, can be reinforced by administering cortisol. However, the team headed by Professor Armin Zlomuzica at Zentrum für Psychotherapie (psychotherapy center) at Ruhr-Universität Bochum (RUB) has demonstrated with a group of arachnophobics that an application of cortisol after exposure is not beneficial for the patients. Rubin, the RUB's science magazine, reports about the results which were also published in the scientific journal Psychoneuroendocrinology. "Various studies have shown that extinction can be accelerated or reinforced in healthy individuals by administering the stress hormone cortisol," says Armin Zlomuzica. In these studies, patients always took cortisol prior to the therapy. The team from Bochum has now tested what happens if the drug is administered after exposure to the triggering object. The idea was that they would be able to use the pharmaceutical agent after successful exposure, thus reinforcing only the positive therapy outcomes.

Neochromosome Announces Successful Collaboration with Sumitovant Biopharma

Sumitovant Biopharma, Inc. | January 20, 2023

On January 19, 2023, Neochromosome, Inc., announced a partnership with Sumitovant Biopharma, Inc., a technology-driven biopharmaceutical firm expediting the discovery and commercialization of novel therapeutics. This collaboration blends Neochromosome's neoYeast™ platform with Sumitovant's DrugOME™ computational ecosystem to identify new proteins that would benefit from non-canonical amino acid chemistries that are unavailable in nature. As part of the collaboration, Sumitovant used a combination of natural language processing (NLP), artificial intelligence (AI), machine learning (ML), and computational algorithms to identify opportunities for Neochromosome to enhance the discovery and production of proteins limited by evolution and traditional fabrication processes. For example, non-canonical amino acid inclusion allows new-to-nature proteins with improved structures and functions but often requires chemical synthesis, which is expensive, size- and complexity-restricted, and environmentally damaging. neoYeast™, based on Neochromosome's world-leading genome-scale cell engineering technology stack, enables the highly efficient and environmentally friendly integration of non-canonical amino acids into proteins, with both discovery and manufacturing possible in a single genome-engineered yeast strain. Sumitovant used DrugOME to explore libraries of traditional and non-traditional sources of data to recommend targeted protein development candidates for neoYeast. Co-Founder and CEO of Neochromosome, Leslie Mitchell, commented, "The combination of Sumitovant's technology platform and life-sciences expertise with Neochromosome's ability to both discover and biomanufacture novel proteins in a single system enables Neochromosome to accelerate and streamline the delivery of better therapies for patients." She added, "We are excited to partner with the world-class team at Sumitovant to identify opportunities to create better versions of existing drugs, along with new-to-nature compounds, and to manufacture them efficiently at scale."

EyePoint Pharmaceuticals Completes Enrollment in Oversubscribed Phase 2 DAVIO 2 Clinical Trial of EYP-1901 for Maintenance Treatment of Wet AMD

Globenewswire | March 28, 2023

EyePoint Pharmaceuticals, Inc. a company committed to developing and commercializing therapeutics to improve the lives of patients with serious eye disorders, today announced it has completed enrollment in the Phase 2 "Durasert® and Vorolanib in Ophthalmology 2" (DAVIO 2) clinical trial evaluating EYP-1901 as a potential six-month maintenance treatment for wet age-related macular degeneration (wet AMD). The trial exceeded its original target of 144 patients, enrolling a total of 160 patients. All patients were previously treated with a standard-of-care anti-VEGF therapy and were randomly assigned to one of two doses of EYP-1901 or to an aflibercept on-label control. “We are thrilled to announce the completion of enrollment in our oversubscribed Phase 2 DAVIO 2 trial evaluating EYP-1901 in wet AMD, marking an important milestone as we continue to advance our pipeline of innovative sustained delivery treatments for serious eye disorders,” said Nancy Lurker, Chief Executive Officer of EyePoint Pharmaceuticals. “Patients with wet AMD face an immense treatment burden, requiring monthly or bi-monthly eye injections for the rest of their lives in order to prevent severe vision loss. The high level of patient and physician interest we saw in the trial enrollment further demonstrates the great unmet need in this population for a maintenance treatment option that is safe, effective, long-lasting and convenient.” “We look forward to reporting topline data in the fourth quarter of this year. With these data and the promising results from our Phase 1 DAVIO trial, EYP-1901 will have the largest and most robust dataset of any tyrosine kinase inhibitor (TKI) product in development for wet AMD. These data will inform the design of our pivotal Phase 3 clinical trials and provide optionality as we seek to bring this promising product to patients. I would like to thank our dedicated team of employees and clinical partners, as well as the patients who enrolled in the Phase 1 and Phase 2 EYP-1901 trials and their caregivers for advancing the development of EYP-1901,” continued Ms. Lurker. DAVIO 2 is a randomized, controlled Phase 2 clinical trial of EYP-1901 in patients with wet AMD. Originally designed to enroll 144 patients, the trial enrolled 160 patients in total due to strong investigator and patient interest. All enrolled patients were previously treated with a standard-of-care anti-VEGF therapy and were randomly assigned to one of two doses of EYP-1901 (approximately 2 mg or 3 mg) or an aflibercept control. EYP-1901 is delivered with a single intravitreal injection in the physician's office, similar to current FDA approved anti-VEGF treatments. The primary efficacy endpoint of the DAVIO 2 trial is change in best corrected visual acuity (BCVA) compared to the aflibercept control, six-months after the EYP-1901 injection. Secondary efficacy endpoints include change in central subfield thickness (CST) as measured by optical coherence tomography (OCT), number of eyes that remain free of supplemental anti-VEGF injections, number of aflibercept injections in each group, and safety. “Our ‘Treat to Maintain’ therapeutic approach for EYP-1901 has the potential to transform the wet AMD treatment paradigm, and we are incredibly pleased to complete enrollment with more patients than planned in the DAVIO 2 clinical trial due to high demand to participate from investigators and patients,” said Jay Duker, M.D., President and Chief Operating Officer of EyePoint Pharmaceuticals. “The compelling Phase 1 DAVIO results demonstrate EYP-1901’s potential to transition a majority of patients to an every-six-month treatment for wet AMD, representing a ‘treat to maintain’ therapeutic approach that uses EYP-1901 as a baseline therapy following the use of large molecule anti-VEGFs with the goal of significantly extending the patient’s treatment interval. Based on the extensive prior clinical data evaluating Durasert in four FDA-approved indications, we are confident in EYP-1901’s ability to consistently deliver the active drug, vorolanib, with zero-order drug release kinetics using our bioerodible sustained delivery technology, Durasert® E. In addition, vorolanib brings a new mechanism of action for wet AMD patients and may have additional neuroprotective benefits. We are confident in EYP-1901’s potential to enhance treatment compliance, improve clinical experience and, ultimately, result in better patient outcomes.” About EYP-1901 EYP-1901 is being developed as an investigational sustained delivery treatment combining a bioerodible formulation of EyePoint's proprietary Durasert® delivery technology (Durasert® E) with vorolanib, a tyrosine kinase inhibitor. Positive safety and efficacy data from the DAVIO Phase 1 clinical trial of EYP-1901 showed a positive safety profile with stable visual acuity and OCT. Further, 53% and 35% of eyes did not require any supplemental anti-VEGF injections up to six and twelve months, respectively, following a single dose of EYP-1901. Phase 2 studies are underway for wet AMD and non-proliferative diabetic retinopathy and are planned in diabetic macular edema. Vorolanib is licensed to EyePoint exclusively by Equinox Sciences for the localized treatment of all ophthalmic diseases.
