ElevateBio has raised $401m in a Series D financing round for advancing its technology platforms to expedite the design, production and development of cell and gene therapies. The technology platforms include the Life Editgeneediting platform, an RNA, cell, protein, vector engineering and induced pluripotent stem cells (iPSCs) platform.
Gene therapy is a new therapeutic approach in which genes are used to treat or prevent diseases. It is a comprehensive term which encompasses a large variety of therapy products including viral and bacterial vectors, plasmid DNA, human geneediting technology, and patient-specific cellular gene therapy.
So far, human trial data for gene-editing drugs have been generated for ex vivo therapies, meaning the CRISPR technology is used to modify cells outside the body, which are then reinfused into the patient. — Eric Topol (@EricTopol) June 26, 2021. . — Eric Topol (@EricTopol) June 26, 2021.
Dr Jennifer Harbottle, senior scientist in the R&D Base Editing team of PerkinElmer’s Horizon Discovery business, looks at progress made in the realms of biotechnology and next-generation diagnostics, vaccines and therapeutics, including the application of CRISPR-Cas9 geneediting in developing and refining cell therapies.
The RNA Revolution: From mRNA Vaccines to RNAEditing. The age of RNA is officially here, and it’s here to stay as more than a passing life science trend. RNA technology is not new nor has its potential been surprising. RNA in the Making. So why did this perceived RNA ‘revolution’ take so long?
Previously, messenger RNA (mRNA) therapies were a niche part of the global R&D pipeline, now a wide section of the public is at least familiar with the name of this type of therapy. The biotech is focused on mRNA but has developed a self-amplifying mRNA (sa-RNA) platform in an attempt to develop the potential of the technology further.
By combining CRISPR technology with a protein designed with artificial intelligence (AI), it is possible to awaken individual dormant genes by disabling the chemical “off switches” that silence them. These methyl groups must be refreshed so if PRC2 is blocked the genes it has silenced. Cas9 binds and uses RNA as an address-tag.
Alnylam Pharmaceuticals announced promising results from its HELIOS-B Phase III clinical trial evaluating vutrisiran, an investigational RNA interference (RNAi) therapeutic for treating transthyretin amyloidosis with cardiomyopathy (ATTR-CM). As of March 2024, the FDA has approved six small interfering RNA (siRNA) therapies.
Tofersen (Intrathecal injection) This is an antisense oligonucleotide (ASO) that targets SOD1 mRNA to reduce the synthesis of SOD1 protein. An area of interest has been deciphering ALS’s genetic underpinnings and delivering functional copies of dysfunctional genes to the patient.
Scientists in Israel have used the CRISPR Cas-9 geneediting system to destroy cancerous cells in mice without damaging other cells. The product is the most advanced gene-editing approach in development for transfusion-dependent beta thalassemia (TDT) and severe sickle cell disease. Photo courtesy of Science Advances.
Bayer strengthens gene therapy portfolio with lipid nanoparticle technology from Acuitas Therapeutics Bayer AG is joining forces with Acuitas Therapeutics, Inc., This delivery technology protects the messenger RNA (mRNA) payload after administration allowing it to be safely and effectively delivered into cells.

Its mechanism of action involves blocking the protein shell (capsid) of the HIV-1 virus, disrupting multiple crucial stages of the viral lifecycle. Over 26 weeks of Sunlenca combined with other antiretroviral drugs, 81 percent of participants achieved HIV RNA suppression, reaching levels low enough to be considered undetectable.
The CRISPR geneediting system consists of the Cas9 enzyme, which serves as molecular scissors to cleave double-stranded DNA, and a guide RNA template targeted to a specific genomic sequence, which allows for precise editing. Epigenetic Editing with CRISPR.
“For the first time, we identified a crucial interaction between platelets and the tumor via their surface proteins,” Jain said. The team also works with Dr. Gang Bao, a geneediting expert from Rice University. However, the actual mechanism behind this process remains mostly unknown, until now. ” ###.

Johnson & Johnson’s Top 5 Best-Selling Drugs of 2022: 1) Stelara (ustekinumab) Stelara is an immunosuppressant biologic therapy that blocks the IL-12 and IL-23 proteins that play a role in plaque psoriasis and Crohn’s disease. The monoclonal antibody targets CD20, a protein found on the surface of B lymphocytes (B cells).
From rare disease drug approvals to treatments involving immunotherapies and gene therapies and awarding of a Nobel Prize to the inventors of the gene-editing tool CRISPR, 2020 was a year of great activity and productivity despite the backdrop of the pandemic. CRISPR GeneEditing Inventors Win Nobel Prize.
It helps explain why women with the disease survive longer with less severe symptoms than men during the early stages of the Alzheimer’s, despite having the same levels of toxic amyloid beta and tau proteins in their brains. The gene, called KDM6A , is a histone demethylase that is believed to function as a tumor suppressor.
From leveraging artificial intelligence (AI) to streamline diagnostics and treatments to exploring the untapped potential of RNA-based therapeutics, biotechnology is shaping the future of healthcare and beyond. As of January 31, 2024, approximately 131 unique RNA-based therapies are in clinical development across various therapeutic areas.
