Continue Reading GLOBAL PORPHYRIA DAY IS MAY 18 - United Porphyrias Aims to Raise Awareness, Research and Support for Rare Disease Post this Global Porphyria Day is May 18, 2024 Porphyria is a group of disease of eight rare, genetic disorders. People living with a porphyria have changes to certain genes involved in development of heme, an essential element bringing oxygen into the bloodstream. Each type of porphyria is caused by a defect in a specific enzyme responsible for heme production, causing a buildup of other compounds, called porphyrins. The buildup of porphyrins causes different types of porphyria and associated symptoms, including significant pain. These symptoms can be broadly divided into two categories: acute (sudden and severe) and cutaneous (skin related.) Symptoms range from severe abdominal pain, nausea, vomiting, and effects on the nervous system in acute porphyria to photosensitivity which can cause skin pain, burning, tingling, itching, swelling, blistering, infections, scarring in cutaneous porphyria. UPA supports global efforts to raise awareness of porphyria improving diagnosis and treatment of these rare diseases and providing critical support to the porphyria community. UPA's internationally renowned scientific advisory board of porphyria experts works closely with the patient community to make advances. "The porphyrias are often misdiagnosed and misunderstood by the medical community," said UPA President and porphyria caregiver, Kristen Wheeden, "Our work leads directly to earlier diagnosis, better patient care, increased research, and access to therapeutics. Everyone has the right to live without pain." The United Porphyrias Association is committed to improving the quality of life of the porphyria patient community and is relentlessly focused on advancing disease awareness, research, and therapies in all the porphyrias.

In addition, CRISPR Therapeutics announced the expansion of its in vivo pipeline with two new programs. CTX340™ and CTX450™ utilize LNP-based delivery of CRISPR/Cas9 gene editing cargo to the liver, targeting angiotensinogen (AGT) for refractory hypertension and 5’-aminolevulinate synthase 1 (ALAS1) for acute hepatic porphyria (AHP), respectively. “Over the past two years, we have made significant progress on the development of our lipid nanoparticle platform for the delivery of CRISPR/Cas9 to the liver and are now in clinical trials with CTX310 and CTX320,” said Samarth Kulkarni, Chief Executive and Chairman of the Board of CRISPR Therapeutics. “The expansion of our in vivo pipeline speaks to the scalability of the platform and the exceptional translation capabilities of our team. We continue to add programs to treat both common and rare diseases, as we look to broaden the number of areas where CRISPR could have transformational impact.” In Vivo Pipeline Expansion CRISPR Therapeutics has established a proprietary LNP platform for the delivery of CRISPR/Cas9 to the liver. The first two in vivo programs utilizing this proprietary platform, CTX310™ and CTX320™, are directed towards validated therapeutic targets associated with cardiovascular disease, and are in on-going clinical trials. The addition of two more programs, CTX340 and CTX450, utilizing this LNP delivery technology demonstrates the modularity and scalability of the platform.Refractory hypertension is a serious unmet medical need affecting approximately 1.5 million patients in the U.S. alone. CTX340 is designed to inhibit production of hepatic angiotensinogen (AGT), a validated target to modulate the renin-angiotensin-aldosterone system (RAAS) and normalize blood pressure durably with a one-time treatment. In preclinical studies, CTX340 showed ~60% liver editing and ~90% AGT protein reduction, resulting in sustained ~30 mmHg blood pressure (BP) reduction out to 3 months in the spontaneously hypertensive rat (SHR) model.Acute hepatic porphyria (AHP) is a group of rare genetic diseases of heme biosynthesis. Symptomatic patients have acute attacks, characterized by debilitating neurovascular symptoms, as well as multiple chronic symptoms, such as pain. There are approximately 5,000 patients diagnosed with AHP in the U.S., although the disease remains underdiagnosed. CTX450 is specifically designed to inhibit production of ALAS1 in the liver, preventing accumulation of neurotoxic aminolevulinic acid (ALA) and porphobilinogen (PBG). In preclinical studies, CTX450 showed ~70% liver editing and ~97% ALAS1 protein reduction, resulting in reduction of ALA and PBG disease biomarkers to normal levels in an AHP mouse model.CRISPR Therapeutics has initiated IND/CTA-enabling studies for CTX340 and CTX450 and expects to initiate both clinical trials in the second half of 2025. ASGCT Presentation In addition to expanding the liver-targeted in vivo pipeline, CRISPR Therapeutics reported initial data demonstrating its proprietary capabilities to deliver to and edit genes in the eye, opening a potential new focus area. The data will be presented today, May 8, 2024, from 3:00 p.m. – 3:15 p.m. ET at ASGCT in an oral presentation entitled “Development of an In Vivo Non-Viral Ocular Editing Platform and Application to Potential Treatments for Glaucoma.”Glaucoma is the second leading cause of blindness worldwide. Mutations in the myocilin (MYOC) gene represent the most common genetic cause of glaucoma that affects approximately 150,000 people in the U.S. alone. In these patients, defective myocilin protein aggregates in the trabecular meshwork (TM) cells, leading to impaired outflow of aqueous humor from the anterior segment of the eye, resulting in elevated intraocular pressure. Patients with MYOC-associated glaucoma typically have an earlier onset and more rapidly progressive disease course than is seen with other causes of glaucoma. Pharmaceutical interventions carry a significant treatment burden resulting in reduced adherence to therapy and surgical interventions frequently do not lead to a durable resolution of elevated intraocular pressure (IOP). The Company has developed an LNP platform capable of delivering gene editing cargo to the TM cells in the eye. In today’s presentation, the Company presented data demonstrating efficient and specific delivery to TM cells in mouse, non-human primate, and ex vivo human eyes. The Company showed >90% editing of the MYOC gene in vitro with prioritized guide RNA, and ~90% reduction of surrogate protein expression in a mouse in vivo model after a single injection.
