Clinical trial experts have called for a new ‘toolbox’ to help simplify early-phase clinical trials in a new article published in the British Journal of Clinical Pharmacology to ensure patient safety and the advancement of novel therapies through development. According to the article, Oxford University and Imperial College London’s professor Charles Vincent and Richmond Pharmacology’s Dr Ulrike Lorch stated: “Early phase trials… require a different approach to standards and guidelines akin to the ‘mass customisation’ seen in industry…, [which] allows products to be made to individual customer requirements.” However, this is “only achievable because each of the many components is built in a standard fashion with rigorous quality control,” they added. The authors stated that the clinical trial regulation principle should be to achieve “lean processes that can be easily understood and followed” and that the UK “needs a toolbox of standards, guidelines and local work instructions that can be customised to the requirements of any particular trial and patient group”, as opposed to more documents and checklists, to help bridge the gap between regulation and reality. In an effort to achieve this objective, the authors proposed a number of recommendations, including the representation of experienced investigators and clinical researchers in the development of relevant regulations and guidelines; creating modules of regulation and regulatory guidance to be updated frequently to counteract the current lag in clinical trial practice; and certifying sites, researchers and investigators to achieve faster regulatory authorisation timelines for trusted organisations and personnel. Despite this, the authors state that “rules are never sufficient to ensure safety in practice” and instead recommend that standardisation and compliance “should be combined with agility to adapt to change and innovation”, which will require the training of a whole new generation of researchers to manage risk and protect patients in early-phase clinical trials. Similarly, in June, the European Medicines Agency announced the launch of two advisory pilots to improve the quality of applications for clinical trials in Europe, while the US Food and Drug Administration published guidance to assist drugmakers and medical device makers when submitting Diversity Action Plans to improve enrolment in clinical studies.

CAMBRIDGE, Mass., June 17, 2024 (GLOBE NEWSWIRE) --Intellia Therapeutics, Inc. (NASDAQ:NTLA), a leading clinical-stage gene editing company focused on revolutionizing medicine with CRISPR-based therapies, today announced the acceptance of an abstract featuring redosing data from the Phase 1 study of NTLA-2001 has been selected for an oral presentation at the Peripheral Nerve Society Annual Meeting, taking place June 22 – 25 in Montreal, Canada. NTLA-2001 is an investigational in vivo CRISPR-based gene editing therapy designed to be a single-dose treatment for transthyretin (ATTR) amyloidosis. In the dose-escalation portion of the Phase 1 study, the initial three patients received the lowest dose of 0.1 mg/kg and subsequently received a follow-on dose of 55 mg. These data will be the first-ever clinical data from patients redosed with an in vivo CRISPR-based gene editing candidate and provide insight on the safety and pharmacodynamic effect. While repeat dosing is not planned for the NTLA-2001 program for ATTR amyloidosis, a redosing option could be an important advantage of Intellia’s non-viral, lipid nanoparticle (LNP)-based delivery platform for future investigational therapies where a target additive effect is desired. Presentation Details Title: Activity of Follow-On Dosing for an Investigational In Vivo CRISPR-Based LNP Therapy in Transthyretin Amyloidosis Session: Richard A.C. Hughes Symposium – Clinical Highlights – Late Breaking Abstracts and Clinical Trials Date and Time: Tuesday, June 25, 2024, from 3:45 p.m. – 4:00 p.m. EST Presenter: Jorg Taubel, M.D., FFPM, FESC, Visiting Professor at King’s College London and Chief Executive Officer of Richmond Pharmacology About NTLA-2001 Based on Nobel Prize-winning CRISPR/Cas9 technology, NTLA-2001 has the potential to become the first one-time treatment for transthyretin (ATTR) amyloidosis. NTLA-2001 is designed to inactivate the TTR gene that encodes for the transthyretin (TTR) protein. NTLA-2001 is the first investigational CRISPR therapy to be administered systemically to edit genes inside the human body. Interim Phase 1 clinical data showed the administration of NTLA-2001 led to consistent, deep and long-lasting TTR reduction. Intellia leads development and commercialization of NTLA-2001 as part of a multi-target discovery, development and commercialization collaboration with Regeneron. About Transthyretin (ATTR) Amyloidosis Transthyretin amyloidosis, or ATTR amyloidosis, is a rare, progressive and fatal disease. Hereditary ATTR (ATTRv) amyloidosis occurs when a person is born with mutations in the TTR gene, which causes the liver to produce structurally abnormal transthyretin (TTR) protein with a propensity to misfold. These damaged proteins build up as amyloid in the body, causing serious complications in multiple tissues, including the heart, nerves and digestive system. ATTRv amyloidosis predominantly manifests as polyneuropathy (ATTRv-PN), which can lead to nerve damage, or cardiomyopathy (ATTRv-CM), which can lead to heart failure. Some individuals without the genetic mutation produce non-mutated, or wild-type TTR proteins that become unstable over time, misfolding and aggregating in disease-causing amyloid deposits. This condition, called wild-type ATTR (ATTRwt) amyloidosis, primarily affects the heart. There are an estimated 50,000 people worldwide living with ATTRv amyloidosis and between 200,000 and 500,000 people with ATTRwt amyloidosis. There is no known cure for ATTR amyloidosis and currently available medications are limited to slowing accumulation of misfolded TTR protein. About Intellia Therapeutics Intellia Therapeutics, Inc.

CAMBRIDGE, Mass., March 18, 2024 (GLOBE NEWSWIRE) -- Intellia Therapeutics, Inc. (NASDAQ:NTLA), a leading clinical-stage gene editing company focused on revolutionizing medicine with CRISPR-based therapies, today announced the first patient dosed in the global pivotal, Phase 3 MAGNITUDE trial of NTLA-2001. NTLA-2001 is an investigational in vivo CRISPR-based therapy designed as a single-dose treatment to inactivate the TTR gene and thereby prevent the production of TTR protein for the treatment of transthyretin (ATTR) amyloidosis. The MAGNITUDE trial is evaluating the efficacy and safety of NTLA-2001 in patients with ATTR amyloidosis with cardiomyopathy. “Dosing of the first patient in the MAGNITUDE trial of NTLA-2001 puts us one step closer to bringing a potential one-time gene editing treatment to people living with ATTR amyloidosis,” said Intellia President and Chief Executive Officer John Leonard, M.D. “With multiple sites now enrolling patients, including in the U.S., we are off to a great start to rapidly enroll this landmark study. MAGNITUDE was informed by the compelling interim Phase 1 results reported last year. These data showed that a single-dose treatment of NTLA-2001 resulted in deep and durable reductions of the TTR protein responsible for the clinical consequences of the disease. We look forward to evaluating the efficacy and safety of NTLA-2001 in patients with cardiomyopathy in the pivotal Phase 3 trial. Assuming a positive outcome, it will pave the way for future global marketing applications, ultimately supporting our goal to bring forth a groundbreaking therapy for the ATTR amyloidosis community.” “The diagnosis of ATTR amyloidosis, a life-threatening condition leading to heart failure and other complications, is rapidly increasing,” said Julian Gillmore, M.D., Ph.D., Professor of Medicine, National Amyloidosis Centre, UCL Division of Medicine, Royal Free Hospital, U.K., and the Phase 3 study’s national coordinating investigator. “We, along with our colleagues at Richmond Pharmacology, are thrilled to be the first to dose a patient in the pivotal trial of NTLA-2001, an in vivo CRISPR-based treatment that offers the potential to dramatically reset the standard of care for people living with this devastating disease. There is remarkable interest from the ATTR amyloidosis patient community for a potential single-dose treatment, and we look forward to contributing to the advancement of novel treatment approaches.” About the MAGNITUDE Study The pivotal Phase 3 MAGNITUDE clinical trial is a randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of NTLA-2001 in approximately 765 patients with transthyretin amyloidosis with cardiomyopathy (ATTR-CM). The primary endpoint of the study is a composite endpoint of cardiovascular (CV)-related mortality and CV-related events. Adult patients with hereditary or wild type ATTR-CM will be randomized 2:1 to receive a single 55 mg infusion of NTLA-2001 or placebo.
