The Food and Drug Administration approved Alnylam’s patisiran for the treatment of peripheral nerve disease (polyneuropathy), which is caused by hereditary transthyretin-mediated amyloidosis (hATTR). This is the first FDA-approved treatment for patients with polyneuropathy caused by hATTR, a rare, debilitating and often fatal genetic disease characterized by the buildup of abnormal amyloid protein in peripheral nerves, the heart and other organs. It is also the first FDA approval of a new class of drugs called small interfering ribonucleic acid (siRNA) treatment.

“This approval is part of a broader wave of advances that allow us to treat disease by actually targeting the root cause, enabling us to arrest or reverse a condition, rather than only being able to slow its progression or treat its symptoms. In this case, the effects of the disease cause a degeneration of the nerves, which can manifest in pain, weakness and loss of mobility,” said FDA Commissioner Scott Gottlieb, M.D. “New technologies like RNA inhibitors, that alter the genetic drivers of a disease, have the potential to transform medicine, so we can better confront and even cure debilitating illnesses. We’re committed to advancing scientific principles that enable the efficient development and review of safe, effective and groundbreaking treatments that have the potential to change patients’ lives.”

RNA acts as a messenger within the body’s cells, carrying instructions from DNA for controlling the synthesis of proteins. RNA interference is a process that occurs naturally within our cells to block how certain genes are expressed. Since its discovery in 1998, scientists have used RNA interference as a tool to investigate gene function and its involvement in health and disease. Researchers at the National Institutes of Health, for example, have used robotic technologies to introduce siRNAs into human cells to individually turn off nearly 22,000 genes.

This new class of drugs, called siRNAs, work by silencing a portion of RNA involved in causing the disease. More specifically, Onpattro encases the siRNA into a lipid nanoparticle to deliver the drug directly into the liver, in an infusion treatment, to alter or halt the production of disease-causing proteins.

Affecting about 50,000 people worldwide, hATTR is a rare condition. It is characterized by the buildup of abnormal deposits of protein fibers called amyloid in the body’s organs and tissues, interfering with their normal functioning. These protein deposits most frequently occur in the peripheral nervous system, which can result in a loss of sensation, pain, or immobility in the arms, legs, hands and feet. Amyloid deposits can also affect the functioning of the heart, kidneys, eyes and gastrointestinal tract. Treatment options have generally focused on symptom management.

Onpattro is designed to interfere with RNA production of an abnormal form of the protein transthyretin (TTR). By preventing the production of TTR, the drug can help reduce the accumulation of amyloid deposits in peripheral nerves, improving symptoms and helping patients better manage the condition.

“There has been a long-standing need for a treatment for hereditary transthyretin-mediated amyloidosis polyneuropathy. This unique targeted therapy offers these patients an innovative treatment for their symptoms that directly affects the underlying basis of this disease,” said Billy Dunn, M.D., director of the Division of Neurology Products in the FDA’s Center for Drug Evaluation and Research.

The efficacy of Onpattro was shown in a clinical trial involving 225 patients, 148 of whom were randomly assigned to receive an Onpattro infusion once every three weeks for 18 months, and 77 of whom were randomly assigned to receive a placebo infusion at the same frequency. The patients who received Onpattro had better outcomes on measures of polyneuropathy including muscle strength, sensation (pain, temperature, numbness), reflexes and autonomic symptoms (blood pressure, heart rate, digestion) compared to those receiving the placebo infusions. Onpattro-treated patients also scored better on assessments of walking, nutritional status and the ability to perform activities of daily living.

The most common adverse reactions reported by patients treated with Onpattro are infusion-related reactions including flushing, back pain, nausea, abdominal pain, dyspnea (difficulty breathing) and headache. All patients who participated in the clinical trials received premedication with a corticosteroid, acetaminophen, and antihistamines (H1 and H2 blockers) to reduce the occurrence of infusion-related reactions. Patients may also experience vision problems including dry eyes, blurred vision and eye floaters (vitreous floaters). Onpattro leads to a decrease in serum vitamin A levels, so patients should take a daily Vitamin A supplement at the recommended daily allowance.

The FDA granted this application Fast Track, Priority Review and Breakthrough Therapy designations. Onpattro also received Orphan Drug designation, which provides incentives to assist and encourage the development of drugs for rare diseases.

Approval of Onpattro was granted to Alnylam Pharmaceuticals, Inc.

The company have together with the UK Cystic Fibrosis Gene Therapy Consortium (GTC), consisting of Imperial College London and the Universities of Oxford and Edinburgh, Imperial Innovations, and Oxford BioMedica (OXB) announced a global collaboration to develop a first-in-class, long-term therapy for patients with cystic fibrosis (CF).

The new partnership brings together the academic partners’ leading expertise in developing gene therapy for CF and OXB’s leading expertise in manufacturing lentiviral vector-based therapies with Boehringer Ingelheim’s capabilities in drug discovery and the clinical development of novel breakthrough therapeutic agents, reports the collaborators.

A possible universal treatment option

The collaboration will focus on a novel approach using a replication-deficient lentiviral vector in an inhaled formulation, to introduce a healthy copy of the CFTR gene into the cells of the lung. This method has demonstrated high gene transfer efficiency and offers the possibility of repeated administration to maintain the therapeutic effect. Gene therapy is the only therapeutic approach to date that can address all CFTR gene mutations, thus potentially offering a universal treatment option.

Three-way partnership

“This novel three-way partnership brings together an unparalleled combination of clinical, scientific, manufacturing and commercial skills in an effort to develop new treatments and make a major contribution to the lives of patients affected by cystic fibrosis,” stated John Dawson, Chief Executive Officer of Oxford BioMedica. “The GTC has been working determinedly for over 15 years to get to this exciting point of forming a partnership with Boehringer Ingelheim, a global pharmaceutical company with respiratory expertise. Our contribution to this partnership reaffirms our leading position in the development and manufacturing of lentiviral vector gene therapy products at large scale. We look forward to working with our new academic and industry partners.”

“Through this collaboration, we are joining forces with some of the top talents in this disease space to propel treatment advances forward,” said Clive R. Wood, Ph.D., Senior Corporate Vice President, Discovery Research at Boehringer Ingelheim. “Bringing together our existing expertise as a leader for nearly a century in the discovery and development of therapies that have advanced patient care in respiratory diseases with the gene therapy knowledge of our partners, we aim to unlock unprecedented opportunities for patients with this devastating disease, who are desperately waiting for better treatment options.”

Collaboration details

Boehringer Ingelheim has received an option to license the exclusive global rights to develop, manufacture, register, and commercialise this lentiviral vector-based gene therapy for the treatment of cystic fibrosis. Financial terms are not disclosed. During the option period the partners will work closely together to pursue the development of this innovative approach financed by Boehringer Ingelheim. The new collaboration is a joint initiative of Boehringer Ingelheim’s Respiratory Therapeutic Area and Research Beyond Borders (RBB), which is one of the pillars of Boehringer Ingelheim’s research and development strategy and explores emerging science, disease areas and technology. It builds on Boehringer Ingelheim’s commitment to early science and its comprehensive approach to respiratory research and development to investigate new treatments that have significant clinical value in areas of high unmet need.

ENPICOM finalized development and released the first version of their ImmunoGenomiX (IGX) platform to support the development, patient stratification and treatment monitoring of immunotherapies.

The adaptive immune system, also known as the acquired immune system, is a subsystem of the overall immune system that is composed of T and B lymphocytes, which eliminate pathogens or prevent their growth. Moreover, the clinical relevance of T cells in the control of different human cancers and autoimmune diseases is beyond doubt. Immunotherapies that boost the ability of T cells to destroy cancer cells have proven therapeutic efficacy in a variety of human malignancies.

ENPICOM develops a T cell and B cell receptor (TCR/BCR) repertoire immunosequencing data analysis solution. This IGX platform will be modularly expanded to become a comprehensive end-to-end immunosequencing data analysis platform designed to analyze, monitor, and compare the immune repertoires in the context of immunotherapy development and at all stages of treatment and disease over time. Starting from high-throughput sequencing data, it will deliver an easy-to-read report depending on the specific application, be it research, diagnosis, patient stratification, or treatment monitoring. The IGX platform will allow customers to use their own sample preparation protocols and the next-generation sequencing technology of choice. It requires no programming skills as the interface is intuitive and flexible.

The first version is available as of today and consists of the base module, IGX Explore, to analyze TCR repertoires from raw sequencing data, report back the number of individual TCR clones and interactively visualize them in a user-friendly way. With IGX Explore (TCR) immunotherapy companies can boost their target discovery, research and drug development processes. In case they need TCR repertoire analysis for a specific application or results visualized in a different way, ENPICOM can custom-build it.

Using a recently published and independent benchmark, ENPICOM showed that IGX Explore offers superior accuracy. The independent benchmark was published in a recent paper by Afzal et al., in which the authors benchmarked ten state-of-the-art TCR repertoire analysis tools. More information about this benchmark study can be found at the company’s website.

Dr. Nicola Bonzanni, Chief Scientific Officer, explains: “An important step in repertoire analysis is the correction of sequencing errors. If sequencing errors were left uncorrected, the richness of a sample would be vastly overestimated; correcting too many errors would lead to under-estimating richness. A critical challenge in immune repertoire analysis is to correct the sequencing errors in the data without losing repertoire-specific information in the process. IGX Explore uses an Adaptive Error Correction algorithm that learns sample-specific mutation rates from the data. By using sample-specific error estimations, erroneous sequences can then be corrected to provide accurate clone sequences, sizes, and frequencies” and adds “These results are very comforting, as highly accurate clonality analysis is the stepping stone towards successful application of this technology in the clinic at later stage”.
