February 28th, 2022 - A review article in Molecular Therapy available online March 10, 2022, explores the non-immunological and immunological processes that may limit or improve durability and the strategies that can be employed to increase the duration of the therapeutic effect. The authors suggest CpG- depletion of AAV vectors as one strategy to enhance long-term transgene expression.

September 8th, 2021 - Dr. Susan Faust is an invited guest speaker presenting at the Gene Therapy Summit, Vector Engineering & Design, taking place in Boston, MA on Apr 12, 2022

1) Short Course: Capsid or Genome: What’s Causing the Transgene-Limiting Immune Response Following AAV Gene Transfer?


2) Podium Presentation: Adeno-Associated Virus (AAV) Gene Transfer of a Localized Immunosuppressant in Cardiac Transplants for the Prevention of Chronic Rejection


July 14th, 2021 - NxGEN Vector Solutions’ CEO, Dr. Susan Faust, is an invited guest speaker at the #VLGeneCellGene and Cell Therapies: CMC, CGT & Vector Manufacturing Summit

November 18-19, 2021| 9:00 CEST |Munich, Germany & Online

Dr. Faust will be speaking on:

  • The desirability of CpG depletion of AAV vectors for the purpose of reducing the immune response to the vector and establishing long-term transgene expression
  • The mechanism by which immunostimulatory CpG motifs limit transgene expression (presenting data from both preclinical and clinical studies) as well as strategies for the future design of AAV vectors


May 24th, 2021 - NxGEN Vector Solutions Announces Issuance of a New U.S. Patent Covering CpG-depleted AAV Vector Technology

May 25th, 2021—NxGEN Vector Solutions announces today that the U.S. Patent and Trademark Office has issued a new Patent, No. 11,015,210, further strengthening the Company’s intellectual property position and coverage for the Company’s CpG-depletion AAV Vector Technology.

The ‘210 patent, entitled, “Constructs and Methods for Delivering Molecules via Viral Vectors with Blunted Innate Immune Responses,” covers a modified recombinant adeno-associated viral vector to reduce the number of CpG di-nucleotides such that an immune response to the vector is reduced.

There are four independent claims and they are drawn to various AAV vector compositions in which the regulatory sequence and the exogenous sequence of the AAV vector is CpG-reduced or CpG-free and the AAV ITRs are wild type or CpG-reduced. The regulatory sequence can be a promoter, an enhancer, an intron, a microRNA, or a polyA signal sequence.

The issued patent demonstrates NxGEN Vector Solutions’ commitment to developing innovative therapies that improve AAV gene therapy outcome by establishing persistent transgene expression, evading immunity, and minimizing infiltration of effector cells. We are pleased with the issuance of the patent and excited about the potential of this technology–which is already being used in clinical trials and has quickly become an industry standard–to improve the safety and efficacy of gene therapies and to ensure that patients who receive gene therapy maintain their therapeutic gene expression.

April 20th, 2021 - 2021—Read the original CpG-depletion AAV vector technology scientific article, Faust et al., JCI, 2013. We were the first to develop and demonstrate that CpG-depleted AAV vectors could establish persistent transgene expression, evade immunity, and minimize infiltration of effector cells. We concluded and accurately predicted that CpG-depleted AAV vectors could improve outcome of clinical trials of gene therapy.

March 18th, 2021 - March 18, 2021–NxGEN Vector Solutions’ CEO, Dr. Susan Faust, is an invited guest speaker at the Vector Engineering & Delivery for Gene Therapies summit to take place on April 20, 2021. Additional information on the presentation can be found below:

Title: Hindsight is 2020: The Advancement of CpG-depleted AAV Vectors as an Industry Standard

The desirability of CpG depletion of AAV vectors for the purpose of reducing the immune response to the vector and establishing long-term transgene expression is a hot topic in the manufacturing sector and of interest to many gene therapists. Dr. Faust is a pioneer in this research and the first to CpG-deplete AAV vectors to circumvent TLR9 activation, a technology that has become an industry standard.

The audience will gain an in depth understanding of the mechanism by which immunostimulatory CpG motifs limit transgene expression (presenting data from both preclinical and clinical studies) as well as strategies for the future design of AAV vectors.
