European Orphan Medicinal Product Designation Granted to Sangamo Therapeutics Investigational CAR-Treg Cell Therapy TX200 for Solid Organ Transplantation
Sangamo Therapeutics, Inc. (NASDAQ: SGMO) announced that the European Commission has granted Orphan Medicinal Product Designation to TX200, a CAR-Treg therapy for solid organ transplantation. This designation aims to reduce transplant rejection and the burden of lifelong immunosuppressive therapy. The STEADFAST Phase 1/2 clinical study has already dosed the first patient in March 2022, with further dosing planned. TX200 is designed to prevent immune rejection in mismatched kidney transplants by promoting immunological tolerance, offering 10 years of market exclusivity upon approval.
- Orphan Medicinal Product Designation granted to TX200, allowing 10 years of market exclusivity upon regulatory approval.
- TX200 aims to significantly reduce the risk of organ rejection and the need for chronic immunosuppressive therapy.
- First patient dosed in the ongoing Phase 1/2 STEADFAST study, indicating clinical progress.
- Clinical trial results are still uncertain and depend on the outcomes of the Phase 1/2 STEADFAST study.
- Potential risks and uncertainties related to the unpredictable nature of clinical trials and regulatory approval processes.
“Patients who have received a solid organ transplant require lifelong surveillance and chronic immunosuppressive medications to manage the risk of transplant rejection,” said
Dosing of the first patient in the STEADFAST Phase 1/2 clinical study took place in
The OMPD status offers a range of incentives to encourage the development of orphan medicines, including protocol assistance on study protocols, potential fee reductions, and 10 years of market exclusivity upon regulatory approval.
About TX200
TX200 is a cell therapy composed of autologous regulatory T cells (Tregs) engineered to express an HLA-A2 Chimeric Antigen Receptor (CAR), with the aim of preventing immune-mediated rejection in HLA-A2 mismatched kidney transplants from a living donor. TX200 is intended to reduce the risk of transplant rejection by suppressing local inflammation and promoting immunological tolerance to the graft. TX200 is being assessed in HLA-A2 negative patients receiving a mismatched HLA-A2 positive kidney from a living donor. TX200 CAR-Treg cells are expected to localize to the graft and activate upon binding to the HLA-A2 antigen. Through their ability to regulate the immune system, TX200 cells may protect the graft from immune-mediated rejection and reduce or eliminate the need for lifelong treatment with immunosuppressants. The first patient in the ongoing STEADFAST Phase 1/2 study was dosed in

Forward-Looking Statements
This press release contains forward-looking statements regarding Sangamo's current expectations. These forward-looking statements include, without limitation, statements relating to: the therapeutic potential of TX200, including its potential clinical benefit to patients receiving HLA-A2 mismatched kidney transplants from a living donor and patients with other autoimmune and inflammatory conditions, and its potential to promote immunological tolerance to a graft and reduce the need for immunosuppressants; the expected localization and activation of TX200 cells; Sangamo’s expectations for dosing additional patients in the Phase 1/2 STEADFAST study and the expected timing thereof; the potential benefits available to Sangamo as a result of the receipt of OMPD for TX200; the design of the Phase 1/2 STEADFAST study; and other statements that are not historical fact. These statements are not guarantees of future performance and are subject to risks and uncertainties that are difficult to predict. Sangamo’s actual results may differ materially and adversely from those expressed. Factors that could cause actual results to differ include, but are not limited to, risks and uncertainties related to: the uncertain timing and unpredictable nature of clinical trials and clinical trial results, including the risks that Phase 1/2 STEADFAST study data will not validate the safety and efficacy of TX200; the research and development process, including the enrollment, operation and results of clinical trials and the presentation of clinical data; the effects of the evolving COVID-19 pandemic and the impacts of the pandemic on the global business environment, healthcare systems and business and operations of Sangamo, including the initiation and operation of clinical trials; the unpredictable regulatory approval process for product candidates across multiple regulatory authorities; the manufacturing of products and product candidates; the commercialization of approved products; the potential for technological developments that obviate technologies used by Sangamo in TX200; and the risks and uncertainties described in Sangamo's filings with the
