LEXINGTON, Mass., Aug. 10, 2020 (GLOBE NEWSWIRE) -- LogicBio Therapeutics, Inc. (Nasdaq:LOGC) (LogicBio or the Company), a company dedicated to extending the reach of genetic medicine with pioneering targeted delivery platforms, today reported financial results for the quarter ended June 30, 2020, provided a business update and announced the U.S. Food and Drug Administration (FDA) has cleared the Companys Investigational New Drug (IND) application for LB-001 for the treatment of methylmalonic acidemia in pediatric patients. LogicBio released a separate press release this morning providing further details on the planned Phase 1/2 clinical design for LB-001.

We are thrilled to have received clearance to move forward with this first-in-human clinical trial with our lead product candidate, LB-001, for the treatment of methylmalonic acidemia, a life-threatening congenital genetic disease with no current therapeutic treatment options. This represents a significant milestone in our goal of bringing a treatment to MMA patients as well as for our GeneRide platform. We have maintained continuous dialogue with the centers of excellence that are planned to participate in the Phase 1/2 clinical trial, and we look forward to activating these sites as quickly as possible, said Fred Chereau, CEO of LogicBio. We have instituted systems attempting to mitigate COVID-19 dynamics on our study start-up process and, based on our best estimates, we plan to enroll our first patient in early 2021.

Commenting on the Next Generation Capsid Program, Mr. Chereau said, We are very excited about the recent advances in our novel capsid program, which has generated liver-tropic capsids intended for use in gene editing technologies such as GeneRide and other gene therapy approaches. We are focused on executing across all of our programs and look forward to sharing further details on our novel capsids in early 2021.

Appointment of Daniel Gruskin, M.D. to SVP, Head of Clinical Development

Daniel Gruskin, M.D. was appointed as SVP, head of clinical development in August 2020. Dr. Gruskin has served as interim head of clinical development of LogicBio since June 2020. In April 2020, Dr. Gruskin started consulting with the Company as a special advisor. Previously, Dr. Gruskin served in roles of increasing responsibility at Sanofi Genzyme, most recently as vice president, head of global medical affairs, rare disease, in which capacity he oversaw medical affairs, life cycle management, scientific affairs and other medical and development activities related to metabolic, rare and/or genetic diseases. Prior to his role at Sanofi Genzyme, Dr. Gruskin served as assistant professor, human genetics and pediatrics at Emory University School of Medicine, where he was also the chief of the genetics section at Childrens Healthcare of Atlanta.

Daniel has been instrumental in leading LB-001 clinical development efforts including getting the IND cleared. His deep experience in genetic medicines and metabolic diseases will serve LogicBio well as we look to execute on our goals for both the GeneRide and Next Generation Capsid platforms in search of transformative medicines, said Mr. Chereau.

About LogicBio Therapeutics

LogicBio Therapeuticsis dedicated to extending the reach of genetic medicine with pioneering targeted delivery platforms.

LogicBios proprietary genome editing technology platform, GeneRide, enables the site-specific integration of a therapeutic transgene without nucleases or exogenous promoters by harnessing the native process of homologous recombination. LogicBio has received FDA clearance for the first-in-human clinical trial of LB-001, a wholly owned genome editing program leveraging GeneRide for the treatment of methylmalonic acidemia. Patient enrollment is expected to begin in early 2021. In addition, LogicBio has a collaboration with Takeda to research and develop LB-301, an investigational therapy leveraging GeneRide for the treatment of the rare pediatric disease Crigler-Najjar syndrome.

LogicBio is also developing a Next Generation Capsid platform for use in gene editing and gene therapies. Data presented have shown that the capsids deliver highly efficient functional transduction of human hepatocytes with improved manufacturability with low levels of pre-existing neutralizing antibodies in human samples. Top-tier capsid candidates from this effort demonstrated significant improvements over benchmark AAVs currently in clinical development. LogicBio is developing these highly potent vectors for internal development candidates and potentially for business development collaborations.

LogicBio is headquartered inLexington, Mass. For more information, please visitwww.logicbio.com.

Forward Looking Statements

This press release contains forward-looking statements within the meaning of the federal securities laws, including those related to the Companys plans to initiate, advance and complete its planned SUNRISE Phase 1/2 clinical trial of LB-001 in MMA; the timing, progress and results of the Companys research and development activities, including those related to the GeneRide technology platform and Next Generation Capsid Program; its plans for LB-301 in Crigler-Najjar; and the sufficiency of its cash and cash equivalents to fund operating expenses and capital expenditure requirements. These are not statements of historical facts and are based on managements beliefs and assumptions and on information currently available. They are subject to risks and uncertainties that could cause the actual results and the implementation of the Companys plans to vary materially, including the risks associated with the initiation, cost, timing, progress and results of the Companys current and future research and development activities and preclinical studies and potential future clinical trials. In particular, the impact of the COVID-19 pandemic on the Companys ability to progress with its research, development, manufacturing and regulatory efforts, including the Companys plans to initiate, advance and complete its Phase 1/2 clinical trial for LB-001 in MMA, and the value of and market for the Companys common stock, will depend on future developments that are highly uncertain and cannot be predicted with confidence at this time, such as the ultimate duration of the pandemic, travel restrictions, quarantines, social distancing and business closure requirements in the United States and in other countries, and the effectiveness of actions taken globally to contain and treat the disease. These risks are discussed in the Companys filings with the U.S. Securities and Exchange Commission (SEC), including, without limitation, the Companys Annual Report on Form 10-K filed on March 16, 2020 with the SEC, the Companys Quarterly Report on Form 10-Q filed on May 11, 2020, and the Companys subsequent Quarterly Reports on Form 10-Q and other filings with the SEC.
