EDIT-101 Phase 1/2 BRILLIANCE trial enrolling mid-dose pediatric cohort; clinical data update expected in 2H 2022

EDIT-301 remains on track to dose first sickle cell disease patient in 1H 2022 and first TDT patient in 2022

EDIT-103 for RHO-adRP and EDIT-202 for solid tumors advancing towards IND-enabling studies

CAMBRIDGE, Mass., Feb. 24, 2022 (GLOBE NEWSWIRE) -- Editas Medicine, Inc. (Nasdaq: EDIT), a leading genome editing company, today reported business highlights and financial results for the fourth quarter and full year 2021.

“We’re entering 2022 with an expanded pipeline of clinical programs and new preclinical candidates, enabled by our best-in-class gene editing technologies,” said James C. Mullen, Chairman, President, and Chief Executive Officer, Editas Medicine. “In 2021, we demonstrated the ability to edit in vivo with EDIT-101, supporting continued development and additional ocular opportunities such as EDIT-103 for retinitis pigmentosa, as well as opportunities in other organs. In 2022, we expect to release additional data for EDIT-101, show initial clinical findings for EDIT-301 in sickle cell disease, and begin patient dosing in the beta thalassemia trial. We also expect to begin IND-enabling studies for EDIT-202, the first for our iNK programs.”

Recent Achievements and Outlook

In Vivo Gene Edited Medicines

  • EDIT-101 for LCA10
    First ever in vivo ocular gene editing data demonstrated evidence of gene editing and potential clinical benefit; clinical update expected in 2H 2022
    Editas Medicine completed dosing of all adult cohorts in its BRILLIANCE study of EDIT-101, an investigational treatment for Leber Congenital Amaurosis 10 (LCA10), a CEP290-related retinal degenerative disorder. Previously announced preliminary EDIT-101 clinical results demonstrated a favorable safety profile and encouraging signals of clinical benefit.

    • The Company remains on track to complete dosing of the pediatric mid-dose cohort in the first half of 2022 and expects to initiate dosing of the pediatric high-dose cohort this year.

    • Additionally, the Company is expanding enrollment in one or more of the previously completed adult cohorts to explore dose response and support establishment of registrational trial endpoints, which are anticipated by year-end.

    • Editas Medicine also expects to provide a clinical update on the BRILLIANCE trial in the second half of 2022. The update is expected to provide safety and efficacy assessments on all patients who have had at least six months of follow-up evaluations, which will include at least 12 months of data on the adult mid-dose cohort, and at least six months of data on the adult high-dose cohort.

    • At the upcoming Association for Research in Vision and Ophthalmology (ARVO) annual meeting, the Company will provide a safety profile update on EDIT-101, evaluating viral shedding in the BRILLIANCE trial to determine any risk of systematic viral persistence.

  • EDIT-103 for RHO-adRP
    Advancing towards IND enabling studies; additional non-human primate data to be presented at ARVO
    Editas Medicine is developing EDIT-103 for the treatment of rhodopsin-associated autosomal dominant retinitis pigmentosa (RHO-adRP), a progressive form of retinal degeneration. EDIT-103 uses two adeno-associated virus (AAV) vectors to knock out and replace mutations in the rhodopsin gene in order to preserve photoreceptor function. This approach can potentially address more than 150 gene mutations that cause RHO-adRP. The Company believes that simultaneously knocking out and replacing a gene in the same cell in vivo may lead to addressing other autosomal dominant diseases, where gain of negative function requires correction.

    • Editas Medicine has shown that non-human primate data for EDIT-103 demonstrated more than 95% productive editing and potentially therapeutically effective restoration of normal rhodopsin protein. The program continues to advance towards IND-enabling studies, with additional preclinical data to be presented at the upcoming ARVO annual meeting.

  • EDIT-102 for USH2A
    Productive editing enhanced by approximately 350% compared to initial construct
    An optimized version of EDIT-102 for treatment of Usher syndrome 2A (USH2A)-associated retinitis pigmentosa is in lead optimization. Using a dual-vector approach with an AsCas12a nuclease, Editas Medicine has enhanced productive editing by approximately 350% compared to the initial construct.

  • Editas Medicine expects to declare an additional new development candidate for an in vivo ocular indication in 2022.

Ex Vivo Gene Edited Medicines

  • EDIT-301 for Sickle Cell Disease
    Naturally de-risked approach supported by highly specific and proprietary AsCas12a enzyme; first patient dosing expected in 1H 2022 and initial data expected by year-end
    The Company is developing EDIT-301 for the treatment of sickle cell disease. Following human genetics, Editas is editing the HBG1/2 promoter and disrupting the binding site of BCL11a, consistent with observed naturally occurring human mutations. These mutations mimic the asymptomatic condition Hereditary Persistence of Fetal Hemoglobin (HPFH), thereby ameliorating disease symptoms. EDIT-301 was specifically designed using Editas Medicine’s proprietary engineered AsCas12a enzyme to generate high efficiency edits in multipotent long-term hematopoietic stem cells for sustained efficacy and durability. The Company believes that targeting the HBG1/2 promoter site is potentially a more effective approach with better long-term safety than other editing targets and mechanisms.

    • The Phase 1/2 RUBY trial for the treatment of sickle cell disease is currently enrolling study participants and is on track to begin dosing in the first half of 2022, with initial clinical results expected by year-end.

  • EDIT-301 for TDT
    IND approved; first patient dosed expected in 2022
    Editas Medicine is also developing EDIT-301 for the treatment of transfusion-dependent beta thalassemia (TDT), for which the IND was cleared by the U.S. Food and Drug Administration (FDA) in December 2021. Preparations to initiate a Phase 1/2 clinical trial designed to assess the safety, tolerability, and preliminary efficacy of EDIT-301 for the treatment of TDT are underway. The Company expects to dose the first TDT patient in 2022.

Cellular Therapy

  • EDIT-202 Multiplexed iNK for Solid Tumors
    New preclinical data to be presented at AACR
    Editas Medicine has announced the development candidate EDIT-202, a highly differentiated, iPSC-derived natural killer cell (iNK) investigational medicine with double knock-in and double knock-out edits. These edits serve to enhance adaptive immune response and improve cell proliferation, cytolytic activity and persistence, as well as overcome suppressive tumor microenvironments. This approach has the potential to create an allogeneic “off-the-shelf” NK cell therapy medicine with enhanced activity against solid tumors.

    • Editas Medicine expects to advance this therapy in preclinical development during 2022. Additional in vitro and in vivo preclinical data supporting the development of EDIT-202 as a potential allogeneic cell-based medicine for treating solid tumors will be presented at the next American Associate for Cancer Research (AACR) annual meeting.

  • Alpha-Beta T Cells for Oncology
    Six ongoing programs including one development candidate
    The ongoing collaboration between Editas Medicine and Bristol Myers Squibb (BMS) continues to advance alpha-beta T cell medicines for the treatment of solid and liquid tumors, leveraging Editas Medicine’s unique platform technologies including Cas9 and AsCas12a. BMS has opted into six programs since the start of the collaboration, including one declared development candidate.

Corporate

  • Technology Platform
    Expanded applications for SLEEK platform
    Last year, Editas Medicine announced the development of its SLEEK knock-in technology. The Company believes SLEEK will considerably change the development of gene edited engineered cell therapies, including iPSC-derived, healthy donor-derived, and autologously-derived therapies. More than 95% knock-in efficiencies have been demonstrated using the AsCas12a nuclease in various clinically relevant target cells, including iPSCs, T cells, and NK cells. Additionally, Editas Medicine believes SLEEK may be used to fine-tune the expression levels of transgene cargos, an important attribute of next-generation cell therapy medicines.

  • Leadership
    Strengthened board with two additional directors in 2021
    Last September, Editas Medicine appointed Emma Reeve to its Board of Directors and as Chairperson of the Audit Committee. Ms. Reeve is an accomplished biopharmaceutical executive with more than 25 years of global financial experience across pharmaceutical, medical device, and biopharma companies. Additionally, last October, the Company appointed Bernadette Connaughton to its Board of Directors and as Chairperson of the Company’s Organization, Leadership and Compensation Committee. Ms. Connaughton is an accomplished pharmaceutical executive with more than 30 years of global strategic, commercial, and biopharmaceutical industry expertise.

  • Manufacturing
    Editas Medicine continues to advance internal and external manufacturing capabilities for the Company’s portfolio of in vivo gene edited medicines, ex vivo gene edited cell medicines, and cell therapy medicines. Recent advancements will allow the Company to manufacture high quality guide ribonucleic acid (gRNA) to the appropriate scale, providing potential capital flexibility and lower costs associated with current supply chain infrastructure. The Company believes that these recent advancements will considerably enhance the research & development process.
