- Data from the RESKUE Phase 1/2 clinical trial continues to demonstrate safety and efficacy post-FBX-101 systemic administration in patients recently receiving hematopoietic stem cell transplantation (HSCT), including normalization of motor function and brain development
- First FBX-101 patient dosed in the REKLAIM Phase 1b clinical trial for patients more than 90 days post-HSCT
- Dr. Maria Escolar to present the updated FBX-101 clinical data on Saturday, February 25, 2023, during the 9:00-10:00 a.m. ET session at the WORLDSymposium in Orlando, Florida
COLUMBUS, Ohio – February 23, 2023 – Forge Biologics, a genetic medicines development and manufacturing organization, announced today that Maria Escolar, M.D., Chief Medical Officer, will present updated data from the RESKUE Phase 1/2 clinical trial for FBX-101, the Company’s novel AAV gene therapy for the treatment of patients with Krabbe disease, during the 19th Annual WORLDSymposium being held February 22-26, 2023, in Orlando, Florida. Forge has also dosed the first FBX-101 subject in the REKLAIM Phase 1b clinical trial at the University of Michigan Medical Center.
Patients with infantile Krabbe disease have mutations in the gene encoding the lysosomal enzyme galactocerebrosidase (GALC), which is essential for normal metabolism of myelin components. Absence of GALC results in the accumulation of psychosine, a toxic substrate in cells making myelin, which then causes inflammation, rapid nerve demyelination, and progressive deterioration of the central nervous system (CNS) and peripheral nervous system (PNS). This results in progressive motor disease and often early death of patients by two years of age.
“We are encouraged by the continued safety and efficacy observed in FBX-101 treated patients. Notably, some of the patients were identified by newborn screening, which enabled early disease intervention,” stated Dr. Escolar. “All patients to date have exhibited normal motor function and brain development six and 12 months post-FBX-101 administration, which would not be anticipated in the absence of systemic gene transfer of the GALC gene. We also observed up to 170-fold and 10-fold increases in plasma and cerebrospinal fluid (CSF) GALC levels, respectively, during the six and 12 month follow-up milestones, demonstrating sustained, high expression of the GALC transgene. Importantly, no treatment-related serious adverse events, liver enzymes elevations, nor development of anti-AAVrh10 antibodies have been observed after FBX-101 systemic administration. These results are very encouraging and provide hope for the families impacted by Krabbe.”
Forge has also dosed one subject in the REKLAIM Phase 1b clinical trial for FBX-101 at the University of Michigan Medical Center. The REKLAIM trial is evaluating the safety and efficacy of FBX-101 in asymptomatic infantile or symptomatic late infantile Krabbe disease patients that received HSCT at least 90 days before FBX-101 administration. Children assessed in REKLAIM have received the standard of care (HSCT) and are partially or fully immuno-competent, but are at risk of developing progressive peripheral nerve disease.
Dr. Escolar’s presentation, “First in Human Phase 1/2 Trial of Intravenous FBX-101 (AAVrh10.hGALC) During Hematopoietic Stem Cell Transplantation Increases GALC Activity, Supports Brain Development and Improves Motor Function in Patients with Infantile Krabbe Disease: RESKUE Clinical Trial,” will be delivered at the WORLDSymposium on Saturday, February 25, 2023, during the 9:00-10:00a.m. ET session. The session is also available on demand after February 27, 2023, for people registered who are not able to attend the meeting. A digital poster version will be on display Saturday, February 25, 2023, during the 3:00-4:00 p.m. ET session. For more details on the conference, please visit: https://worldsymposia.org/.
About Krabbe Disease
Krabbe disease is a rare neurodegenerative disease affecting about 1-2.5 in 100,000 people in the U.S. Krabbe disease is caused by autosomal recessive mutations in the galactocerebrosidase (GALC) gene, an enzyme responsible for the breakdown of certain types of sphingolipids, such as psychosine, associated with myelination of the nervous system. Without functional GALC, psychosine accumulates to toxic levels in cells, specifically in cells insulating the nerves in the brain and peripheral nervous system, causing rapid demyelination. Krabbe disease initially manifests in young patients as irritability, developmental delay, and progressive muscle weakness. Symptoms rapidly advance to difficulty swallowing, breathing, and regression of neurodevelopment followed by seizures, vision and hearing loss. Infantile Krabbe disease (0-12 months of age at onset) usually leads to death in untreated patients by two years of age. Late Infantile patients (12-36 months of age at onset) usually die by the age of six. The current standard of care, hematopoietic stem cell transplantation (HSCT), has been shown to stabilize cognitive decline and significantly improve long-term neurological outcomes when performed prior to symptom onset. However, HSCT does not correct the peripheral neuropathy that is progressive as the patient grows, leading to loss of gross motor skills and eventually death. Early diagnosis is key for treating patients with Krabbe disease before symptoms are evident and significant neurological damage has occurred. Currently, 10 states in the U.S. are conducting newborn screening for Krabbe disease. Infants who screen positive due to insufficient GALC activity undergo psychosine testing and mutation analysis to confirm the diagnosis and determine which infants need immediate treatment because they are at high risk to progress.
About FBX-101
FBX-101 was developed to treat children with Krabbe disease. FBX-101 is an adeno-associated viral serotype rh10 (AAVrh10) gene therapy that is delivered intravenously after HSCT infusion. The vector delivers a functional copy of the GALC gene to cells in both the central and peripheral nervous system, and has shown to functionally correct the central and peripheral neuropathy, improve myelination and gross motor function, and significantly prolong lifespan in animal models. This approach also has the potential to overcome some of the immunological safety challenges observed in traditional AAV gene therapies and extend the duration of gene transfer. The FDA has granted FBX-101 Fast Track Designation, Orphan Drug Designation, and Rare Pediatric Disease Designation; the EMA has granted FBX-101 Orphan Drug Designation and Priority Medicines (PRIME) designation.
About the RESKUE Trial
RESKUE is a Phase 1/2 clinical trial to investigate the safety and efficacy of FBX-101 in patients with infantile Krabbe disease. It is a nonblinded, non-randomized dose escalation study in which subjects receive a single intravenous infusion of FBX-101 within 21 to 60 days of HSCT, the current standard of care. Data from extensive natural history subjects will be used to compare as the control group. More information on the RESKUE trial can be found online at https://www.clinicaltrials.gov/ct2/show/NCT04693598.
About the REKLAIM Trial
REKLAIM is a Phase 1b, nonblinded, non-randomized dose escalation clinical trial currently enrolling children with asymptomatic infantile and symptomatic late infantile Krabbe disease to investigate the safety and efficacy of a single intravenous infusion of FBX-101 administered more than 90 days after HSCT, the current standard of care, when the patient is partially or fully immuno-competent. Data from extensive natural history subjects will be used to compare as the control group. More information on the REKLAIM trial can be found online at https://www.clinicaltrials.gov/ct2/show/NCT05739643.

- Clinical data demonstrating initial safety and efficacy from the RESKUE trial are being presented by Chief Medical Officer Maria Escolar, M.D., at the 29th Congress of European Society of Gene & Cell Therapy (ESGCT), October 11-14, 2022
- Subjects treated with FBX-101 have shown increased galactocerebrosidase (GALC) enzyme activity in plasma and cerebrospinal fluid (CSF), normal white matter myelination and normalization of motor development in two children 90 days and 9 months post-treatment
- FBX-101 has been well tolerated, with no treatment related serious adverse events and absence of humoral response against the vector post intravenous administration
- Company will also present data at the Alliance for Regenerative Medicine’s (ARM) Cell & Gene Meeting on the Mesa on October 12, 2022, 9:15 a.m. PT, in Carlsbad, CA
COLUMBUS, Ohio – October 11, 2022 – Forge Biologics, a gene therapy-focused contract development and manufacturing organization, announced today that Chief Medical Officer Maria Escolar, M.D, MS., will present updated clinical data from the RESKUE Phase 1/2 clinical trial for FBX-101—the Company’s novel gene therapy for the treatment of patients with Krabbe disease—during the 29th Congress of the European Society of Gene & Cell Therapy (ESGCT) being held October 11-14, 2022, in Edinburgh, Scotland.
RESKUE is the first-in-human clinical trial where patients with Krabbe disease are administered FBX-101, a systemic adeno-associated virus (AAV) gene replacement strategy, after full myeloablation and hematopoietic stem cell transplantation (HSCT) infusion. Krabbe is a rare, genetic, neurodegenerative leukodystrophy affecting the central nervous system (CNS) and peripheral nervous system (PNS). Krabbe disease affects infants with an incidence rate of 1-2.5 in 100,000 and leads to premature death, often by 2 years of age. Clinical data support preclinical observations that this gene therapy approach after HSCT infusion may lessen many of the immune challenges previously observed with systemic AAV gene delivery and may create a safer environment for gene replacement. Findings also support this novel approach for extending the delivery of gene replacement strategies to target metabolic diseases amenable to HSCT.
The data from treated subjects demonstrate that intravenous FBX-101 after HSCT infusion has been safe and well tolerated. Notably, the data indicate an absence of humoral immune response against the systemically delivered AAV, and significantly increased galactocerebrosidase (GALC) enzyme activity is observed in plasma and cerebrospinal fluid (CSF). Krabbe disease is characterized by mutations in the GALC gene which lead to loss of motor function. All subjects treated to date have also exhibited improved motor activity and normal brain development, which would not be anticipated in the absence of systemic gene transfer of the GALC gene.
“We are excited to present the data from multiple patients in our RESKUE trial and encouraged by the safety and efficacy results observed in FBX-101 treated subjects,” stated Dr. Escolar. “An update on our first cohort data demonstrates that intravenous FBX-101 after HSCT infusion was safe and well tolerated, including increased GALC enzyme activity in plasma and CSF, normal myelination of white matter, and normalization of motor development. The results are exciting and give us hope for patients suffering from Krabbe disease who typically do not live past two years of age untreated.”
Dr. Escolar’s presentation, “Intravenous FBX-101 (AAVrh10.hGALC) following Hematopoietic Stem Cell Transplantation increases GALC activity, supports brain development and improves motor function in patients with Infantile Krabbe Disease: RESKUE Phase 1/2 Clinical Trial,” will be available for all ESGCT attendees on October 11, 2022, and through October 14th.
