New Irish research reveals the secret lives of tiger sharks

phys.org | June 07, 2019

A team of scientists led by experts from Trinity and a US-based NGO have just returned from the Bahamas where they learned all about the secret lives of the region's tiger sharks. Cutting-edge bio-logging devices fixed to the sharks are providing a suite of biological information that has never been collected before, which will help the team assess how the global climate crisis may impact these apex predators. Tiger sharks are classified as 'near threatened' by the International Union for the Conservation of Nature, with commercial and artisanal fishing pressure and infrequent (once every three years) reproduction contributing to this status. Several countries continue to cull populations of tiger sharks given perceived risks to human swimmers, despite some regions having seen declines in shark abundance of ~ 75% in recent decades. These huge (up to 5m in length) animals are found in tropical and sub-tropical oceans worldwide but have always been difficult to study given their aquatic lifestyle. The scientists involved in the current study got around this issue by using their biologging devices on the sharks—with sensors recording video, body temperature, swimming activity and orientation as the animals went about their normal routine. By measuring how temperature influences the sharks' behaviour and swimming performance, the team will be better placed to predict how these animals will respond to future climate change.

Kriya Acquires Redpin Therapeutics, Adding Neurology Pipeline to Gene Therapy Portfolio

Kriya Therapeutics | November 17, 2022

Kriya Therapeutics, Inc., a fully integrated gene therapy company advancing a broad portfolio of innovative therapeutics announced the acquisition of Redpin Therapeutics, Inc., a privately held biotechnology company developing regulatable gene therapies for intractable diseases of the nervous system. The acquisition serves as the foundation for Kriya’s neurology therapeutic area portfolio, with two lead gene therapy programs focused on epilepsy and trigeminal neuralgia. Redpin’s proprietary chemogenetics platform can selectively activate or silence disease-causing neurons, while leaving normal functioning cells unaffected. Currently available treatments for neurological disorders typically rely on systemically administered drugs or surgical interventions to address local neuron dysfunction. However, these approaches can have limited efficacy and off-target side effects. In contrast, chemogenetics leverages gene products that are selectively responsive to a chosen small molecule. Redpin’s technology utilizes gene therapy to express engineered ion channels that are responsive to modulation by the FDA-approved anti-smoking drug varenicline to either inhibit specific overactive neurons or stimulate underactive ones. “Redpin’s innovative chemogenetics platform has the potential to transform the lives of patients suffering from intractable neurological conditions. We are looking forward to integrating Redpin’s platform and pipeline into Kriya’s gene therapy engine as we advance our mission to develop life-changing gene therapies that can address diseases affecting millions of patients around the world.” Shankar Ramaswamy, M.D., Co-Founder and Chief Executive Officer of Kriya “Redpin has a built a breakthrough, validated chemogenetics approach that could have significant potential in the targeted treatment of neurological disorders,” said Dr. Elma Hawkins, Redpin Therapeutics’ President, Chief Executive Officer and Co-founder. “Kriya Therapeutics is the perfect company to take this leading ion channel-based platform forward and deliver an effective treatment option for patients. We look forward to working with the Kriya team to progress these unique targeted therapies to patients in need as rapidly as possible.” Redpin’s investors include 4BIO Capital, Arkin Bio Ventures, Takeda Ventures Inc, New York Ventures and Alexandria Venture Investments. About Epilepsy Epilepsy is a brain disorder that causes recurrent spontaneous seizures. Approximately 3.4 million people in the U.S. suffer from active epilepsy, according to the U.S. Centers for Disease Control and Prevention. Current treatments for epilepsy include medication, neurostimulation and surgery to remove sections of the affected part of the brain. However between 20% to 40% of patients with newly diagnosed epilepsy will become refractory to treatment, and will continue to suffer seizures. Uncontrolled epilepsy can lead to sudden unexpected death in epilepsy (SUDEP). About Trigeminal Neuralgia Trigeminal neuralgia also known as Tic Douloureux, is a severe and chronic disorder that affects the trigeminal, or fifth cranial, nerve. TN patients experience progressive intense stabbing facial pain attacks that can become more severe and last longer over time. Approximately 10,000 to 15,000 new cases of TN occur each year in the U.S., according to the National Organization for Rare Disorders. While currently available treatments include anti-seizure medications and surgical procedures, a significant proportion of patients are refractory to these approaches. About Kriya Therapeutics Kriya is a fully integrated company pioneering novel technologies and therapeutics in gene therapy. The company aims to revolutionize how gene therapies are designed, developed, and manufactured, improving speed to market and delivering significant reductions in cost. The company is advancing a deep and diversified pipeline of innovative gene therapies in multiple therapeutic area divisions, with current pipeline programs in metabolic disorders, neurology and ophthalmology.

Eiger BioPharmaceuticals Provides Update on Plans for Emergency Use Authorization Application Following FDA Feedback

Eiger BioPharmaceuticals, Inc. | October 06, 2022

Eiger BioPharmaceuticals, Inc. a commercial-stage biopharmaceutical company focused on the development of innovative therapies for hepatitis delta virus and other serious diseases, today announced that, following feedback from the U.S. Food and Drug Administration the company will not submit an emergency use authorization application of peginterferon lambda for the treatment of patients with mild-to-moderate COVID-19. Following Eiger's press release on September 6, 2022, the company submitted a pre-EUA meeting request to FDA, as well as additional morbidity and mortality outcomes data and analyses from the investigator-sponsored TOGETHER study. This included further statistical modeling and efficacy analyses of the study's primary and secondary endpoints and long-term follow-up data that the company believes continue to support the initial positive topline outcomes reported in March. In response, FDA denied the request for a pre-EUA meeting. Citing its concerns about the conduct of the TOGETHER study, FDA concluded that any authorization request based on these data is unlikely to meet the statutory criteria for issuance of an EUA in the current context of the pandemic. FDA suggested that, given peginterferon lambda's mechanism of action and the ongoing need for improved COVID-19 therapeutics, Eiger consider requesting an end-of-Phase 2 meeting to discuss a company-sponsored pivotal trial that could support an eventual Biologics License Application. Eiger is evaluating next steps for this program, in the U.S., as well as ex-U.S. emergency use authorization pathways and strategic options for continued development of peginterferon lambda for COVID-19 and other respiratory viral infections. "While we are disappointed that FDA will not consider an EUA application based on results generated from the TOGETHER study, we continue to have strong conviction in the potential of peginterferon lambda to confer a meaningful benefit for patients with COVID-19 and other respiratory viral infections. COVID-19 related deaths remain alarmingly high around the globe, including in the U.S. where, according to recent data from the Centers for Disease Control and Prevention, approximately 400 people die every day from this disease." David Cory, President and CEO, Eiger Eiger is advancing a late-stage pipeline of multiple FDA Breakthrough Therapy designated programs in Phase 3, including lonafarnib and peginterferon lambda for hepatitis delta virus (HDV) infection, and avexitide for congenital hyperinsulinism. The company expects to report topline data from D-LIVR, Eiger's landmark Phase 3 study of lonafarnib-based regimens for HDV, by year end. About TOGETHER Study TOGETHER is an independent multi-center, investigator-sponsored, randomized, placebo-controlled adaptive platform Phase 3 study evaluating therapeutics in newly diagnosed, high-risk, non-hospitalized patients with mild-to-moderate COVID-19. TOGETHER is the largest placebo-controlled study in COVID-19 and has evaluated 11 different therapeutic agents for non-hospitalized COVID-19 patients. The study was ongoing at the time the peginterferon lambda arm was added. The evaluation of peginterferon lambda versus placebo was the second largest study to date of a COVID-19 therapeutic of > 1,900 patients. Eligibility criteria required that all patients had laboratory-confirmed mild or moderate COVID-19 and were randomized within seven days of symptom onset. The study enrolled patients regardless of vaccination status or variant strain of SARS-CoV-2. The primary endpoint was a reduction in risk of clinical outcome comparing hospitalizations or emergency room visits greater than six hours after a single subcutaneous injection of peginterferon lambda versus placebo through Day 28. A key secondary endpoint was reduction in risk of hospitalizations or death in patients when dosed within three days of symptom onset. The TOGETHER study recruited from 12 sites in Brazil and 5 sites in Canada. About Peginterferon Lambda Peginterferon lambda is an investigational late-stage, first-in-class, type III interferon that stimulates immune responses that are critical for the development of host protection during viral infections and has been well-tolerated in clinical studies. Eiger is developing peginterferon lambda for the treatment of HDV infection. Peginterferon lambda has been administered to over 4,000 subjects in 28 clinical trials of HBV, HCV, HDV and COVID-19. Peginterferon lambda is an investigational agent and not yet approved for any indication. Eiger has received Orphan Designation by the U.S. Food and Drug Administration and European Medicines Agency, and Fast Track and Breakthrough Therapy Designation by FDA for peginterferon lambda in HDV. About Eiger Eiger is a commercial-stage biopharmaceutical company focused on the development of innovative therapies for hepatitis delta virus (HDV) and other serious diseases. The Eiger HDV platform includes two first-in-class therapies in Phase 3 that target critical host processes involved in viral replication.
