MaxCyte, Inc. to Present Positive Preclinical Data for Sickle Cell Disease

 

Gaithersburg, Maryland - April 25, 2017: MaxCyte (LSE: MXCT, MXCR) a US-based global company dedicated to driving the acceleration of discovery, development, manufacturing and commercialization of next-generation, cell-based medicines, announced today it will present positive preclinical study results at the American Society of Gene and Cell Therapy Annual Meeting (ASGCT).   The new in vitro data demonstrate the potential of MaxCyte's cGMP-compliant proprietary delivery platform to enable CRISPR gene editing in the treatment of sickle cell disease (SCD). The ASGCT meeting will take place in Washington, DC from May 10-13, 2017.

Using MaxCyte's Proprietary GT® System, MaxCyte and its collaborators at the National Heart, Lung and Blood Institute (NHLBI) and National Institute of Allergy and Infectious Diseases (NIAID) demonstrated successful CRISPR-induced corrections of the mutation behind SCD in more than 30 percent of patient-derived B cells. The objective of this pre-clinical effort is to develop potential curative therapy based on "correcting" the faulty gene in SCD while concurrently addressing DNA mutation sites in non-corrected cells that further contribute to the disease in people living with SCD. In contrast, competing approaches focus on either external therapeutic gene addition using viral vectors (now in early clinical trials) or on creation of hereditary persistence of fetal hemoglobin (HPFH) mutations (preclinical research underway). Neither of these approaches impact the level of faulty HbS levels, which is the target of MaxCyte's approach and which are at the core of SCD.

"These data represent an extension of our previously published work achieving gene correction in X-linked chronic granulomatous disease, demonstrating the ability of our cGMP-compliant delivery platform to achieve robust, scalable, and a clinically relevant levels of gene correction in sickle cell disease patient-derived cells," said Doug Doerfler, Chief Executive Officer of MaxCyte, "We are excited by these results, and look forward to evaluating long-term data."

Data will be shared via a poster (Permanent Abstract Number: 642) at the ASGCT Annual Meeting with details as follows: Session: "Clinical-Meaningful Level CRISPR-Oligomer-Mediated Correction of Sickle Cell Disease (SCD) Using Non-viral, cGMP Compliance, Scalable and Closed System."  Timing: Friday, May 12, 2017 at 5:45 - 7:45 p.m. ET 

About Sickle Cell Disease

According to the NHLBI, the term sickle cell disease (SCD) describes a group of inherited red blood cell disorders. Patients with SCD have abnormal hemoglobin, called hemoglobin S or sickle hemoglobin, in their red blood cells. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. Those who have SCD inherit two abnormal hemoglobin genes, one from each parent. In all forms of SCD, at least one of the two abnormal genes cause a person's body to make hemoglobin S.

 

Sickle cell disease is a life-long illness. The severity of the disease varies widely from person to person. In high-income countries like the United States, according to NHLBI, the life expectancy of a person with SCD is now about 40-60 years. Currently, hematopoietic stem cell transplantation (HSCT) is the only cure for SCD. Unfortunately, most people with SCD are either too old for a transplant or don't have a relative who is a good enough genetic match for them to act as a donor. A well-matched donor is needed to have the best chance for a successful transplant. While there are some treatments that can reduce symptoms and prolong life, more medical options are needed.
