Gene Therapy Development

Classified as an advanced therapy medicinal product (ATMP), gene therapy is subject to specific regulations and requires sophisticated testing technologies to bring to market. From regulatory expertise to a comprehensive portfolio of discovery through manufacturing services, you’ll find everything you need to make your gene therapy a reality at Charles River.

Ease the integration of genetically created models with your downstream discovery using our genetic model creation and contract breeding services. If a genetic model exists, our decades of breeding experience can get you the cohorts needed.

Donated human cells. Validate your target with optimal starting materials. Our HemaCare line of products ensures a consistent, reliable and quality-controlled human donor cells.

Immunodeficient mouse models. Test your therapy in models that effectively host human tissue.

CRISPR/Cas 9 gene editing. Use CRISPR technology as a cost-effective method for cellular assay development in a variety of early discovery applications.

Antisense oligonucleotide screening. Accelerate your hit ID and optimization of the optimal ASO with our in vitro screening platform.

Successful development of an ATMP, such as a gene therapy, involves a program that is exclusive to a drug candidate and patient population, while encompassing broad regulatory expectations. Meet the unique and diverse challenges of gene therapy with a team approach that includes experts in pharmacology, toxicology, immunology, bioanalysis, molecular biology, guided by extensive regulatory insight.

We can help you to identify key questions to establish proof of concept (e.g., efficacy or gene modulation), evaluate biodistribution, and outline goals for pilot and definitive safety assessment. However, study design, and subsequent conduct, is only a first step. In a true collaborative effort, we’ll work closely with you and your team to establish a comprehensive and sound nonclinical data package and providing scientific and regulatory support throughout the development process.

Trust our team’s robust, reliable methods for clinical sample analysis. From the start of your nonclinical program through subsequent testing, our scientists collaborate as part of your clinical team. This approach results in robust and reliable methods for clinical sample analysis, which, when combined with data management, enables us to deliver high-quality on-time clinical data to support your drug approval.

Our well-established experience in sample management and kit assembly for Phase I through III clinical trials worldwide is reflected in the 1,300+ sample kits we produce per month. We also offer extensive biomarker testing services, including clinical efficacy/PD biomarkers that allow you to confirm target engagement, and improve your chance of reaching Phase III clinical trials. Our CLIA certification enables us to develop novel biomarkers for use in diagnostic testing, post-market patient safety monitoring, and companion diagnostic testing.

Frequently Asked Questions (FAQs) about Gene Therapy

  • What is a gene therapy?

    Genes are responsible for creating the proteins the control cellular processes. In many diseases, genetic instructions are missing or defective. Scientists first identify the implicated gene in patient cells then create and modify a copy so that it functions properly. The gene “therapy” is then transmitted back to the patient via vector. Once delivered to patient cells, the gene therapy provides instructions for creating the intended protein, correcting the defect.

  • What is an ATMP (advanced therapeutic medicinal product)?

    An advanced therapeutic medicinal product, or ATMP, categorizes a class of therapies derived from genes, somatic cells (cells that do not produce eggs or sperm), or tissue products. The development of ATMPs is governed by a specific set of regulations that differ from other kinds of therapies.

  • What is the difference between a gene and cell therapy?

    Both considered an advanced therapeutic medicinal product, or ATMP, a gene therapy uses genetic material to modify the function of patient cells in the treatment of inherited or acquired disease, while a cell therapy involves the infusion or transplantation of whole cells (e.g., bone marrow transplant or CAR-T).

  • What is a viral vector?

    A viral vector is a gene therapy delivery system. Typically created from a virus called an adeno-associated virus (AAV), naturally occurring entity known not to cause illness in people, the AAV vector is an ideal vehicle to transmit gene therapies to the body.

  • What are the most common viral vectors for gene therapies?

    Typically, gene therapy development uses adeno-associated viruses (AAV), but the following viral vectors can be used (amongst others not listed here which are less common):

    • Retrovirus
    • Lentivirus
    • Adenovirus
