Researchers discover sustainable and natural alternative to man-made chemical pesticides

Phys.org | March 04, 2019

Repurposing a strain of beneficial bacteria could offer a safe, sustainable and natural alternative to man-made chemical pesticides, according to research from Cardiff University. Finding natural approaches to sustainable agriculture and food production is a major global challenge. Synthetic chemical pesticides have traditionally been used to protect crops, but there are growing concerns around their toxicity and the threat they pose to ecosystems. Using genomic techniques, the team of researchers discovered that Burkholderia ambifaria bacteria have the potential to be used as biopesticides that are both effective and safe. Biopesticides offer a natural means of protection and the group of bacteria called Burkholderia have been successfully used to protect crops against diseases. However, in the 1990s, Burkholderia bacteria were linked to serious lung infections in people with cystic fibrosis (CF), leading to concerns about their safety and eventual withdrawal of these biopesticides from the market.

Tiziana Life Sciences Announces Grant received by the Brigham and Women’s Hospital to Explore the Use of Intranasal anti-CD3 mAb

Tiziana Life Sciences Ltd. | September 16, 2022

Tiziana Life Sciences Ltd. a biotechnology company developing breakthrough immunomodulation therapies via novel routes of drug delivery, today announces that a Lawrence & Isabel Barnett Drug Development Program Grant will be awarded to the Ann Romney Center for Neurologic Diseases at the Brigham and Women’s Hospital by the ALS Association for the study of an intranasal anti-CD3 monoclonal antibody in an animal model of Amyotrophic Lateral Sclerosis (ALS). Howard L. Weiner, M.D., Co-Director of the Ann Romney Center for Neurologic Diseases at BWH and Chairman of Tiziana's Scientific Advisory Board, stated, “This prestigious research grant will be used to further study the role of intranasal anti-CD3 mAb in dampening the microglial activation which amplifies ALS disease progression. This research follows our recently presented positive findings on intranasal anti-CD3 mAb in Alzheimer’s Disease preclinical models of neuroinflammation. Additionally, we are currently studying foralumab, the first entirely human anti-CD3 mAb, in patients with secondary progressive multiple sclerosis.” Gabriele Cerrone, Executive Chairman and interim Chief Executive Officer of Tiziana, remarked, “Intranasal foralumab has demonstrated potential across multiple Central Nervous System (CNS) indications. We are encouraged by the preclinical research using an intranasal anti-CD3 mAb in the neuroinflammatory related diseases of ALS and Alzheimer’s, as well as the impressive clinical benefits we have already shown for foralumab in patients with multiple sclerosis. While our initial focus is on our ongoing MS program which will continue to generate clinical read-outs, we are excited by foralumab’s potential to help highly debilitated ALS patients with limited therapeutic options and high unmet need.” “We have now seen the potential of intranasal foralumab to dampen microglial activation in three major neuroinflammatory-related diseases, which creates significant optionality for exploring its benefits in some of the most important and burdensome medical conditions of our time.” Matthew W. Davis, M.D., RPh, Chief Medical Officer of Tiziana About the Barnett Drug Development Grant The ALS Association’s Barnett Drug Development grant program supports preclinical drug discovery and development of new or repurposed treatments for ALS. There is an urgent need for new and improved therapies for ALS, as there is still no cure. The Lawrence and Isabel Barnett Drug Development Program is open to industry and academic investigators proposing to develop novel or repositioning approaches for ALS. The Association seeks applications for the preclinical assessment of therapeutics for ALS that have a high probability of reaching the clinic within three years. About Foralumab Foralumab the only entirely human anti-CD3 mAb, has shown reduced release of cytokines after IV administration in healthy volunteers and in patients with Crohn's disease. In a humanized mouse model it was shown that while targeting the T-cell receptor, orally administered foralumab modulates immune responses of the T-cells and enhances regulatory T-cells thereby providing therapeutic benefit in treating inflammatory and autoimmune diseases without the occurrence of potential adverse events usually associated with parenteral mAb therapy. Once a day treatment for 10 consecutive days with intranasal foralumab was both well tolerated and produced clinical responses in COVID-19 patients. Based on these studies, the intranasal and oral administration of Foralumab offers the potential to become a well-tolerated immunotherapy for autoimmune and inflammatory diseases by the induction of Tregs. About Tiziana Life Sciences Tiziana Life Sciences is a clinical-stage biopharmaceutical company developing breakthrough therapies using transformational drug delivery technologies to enable alternative routes of immunotherapy. Tiziana’s innovative nasal, oral and inhalation approaches in development have the potential to provide an improvement in efficacy as well as safety and tolerability compared to intravenous (IV) delivery. Tiziana’s two lead candidates, intranasal foralumab, the only fully human anti-CD3 mAb, and milciclib, a pan-CDK inhibitor, have both demonstrated a favorable safety profile and clinical response in patients in studies to date. Tiziana’s technology for alternative routes of immunotherapy has been patented with several applications pending and is expected to allow for broad pipeline applications.

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.
