BioLineRx Announces Clinical Trial Agreement with St. Jude Children’s Research Hospital, Inc. to

Evaluate Motixafortide for CD34+ Hematopoietic Stem Cell (HSC) Mobilization

For Gene Therapy Applications in Sickle Cell Disease (SCD)

development from St. Jude Children’s Research Hospital, Inc. and two other clinical sites -

- New trial to expand ongoing clinical research of motixafortide for mobilization of HSCs in

patients with SCD -

TEL AVIV, Israel, May  30, 2024– BioLineRx Ltd. (NASDAQ/TASE: BLRX), a commercial stage biopharmaceutical company pursuing life-changing therapies in oncology and rare diseases, today announced a multi-center Phase 1 clinical trial sponsored  by St. Jude Children’s Research Hospital, Inc. to evaluate motixafortide for the mobilization of CD34+ hematopoietic stem cells (HSCs) used in the development of gene therapies for patients with sickle cell disease (SCD).  Investigators in the trial from St. Jude Children’s Research Hospital, Inc. and two other clinical sites have extensive SCD gene therapy clinical development experience and are recognized leaders in the field.

Hematopoietic stem cell transplantation after genetic modification is potentially curative for patients with SCD.  Significant quantities of HSCs (minimum 16.5-20 million cells/kg) are required for genetic manipulation and transplant success, however, the most commonly used drug for collection of stem cells, granulocyte colony-stimulating factor (G-CSF), is contraindicated in patients with SCD.  Peripheral blood mobilization of stem cells using the mobilization agent plerixafor is the current strategy to collect HSCs for SCD gene therapies, however limitations exist including the need for multiple collection cycles to achieve the necessary HSC yields. For some, gene therapy may be prohibitive by the failure to obtain adequate numbers of HSCs.

“The recent FDA approvals of two gene therapies for sickle cell disease in the U.S. is an exciting development for the sickle cell community,” said Ella Sorani, PhD, Chief Development Officer at BioLineRx.  “Through this new trial with St. Jude, and our ongoing collaboration with investigators at Washington University School of Medicine in St. Louis, we are excited to be working with leaders in gene therapy and stem cell mobilization to evaluate potential new mobilization options for patients with SCD.”

Enrollment in the St. Jude Children’s Research Hospital, Inc. study is expected to begin in the next few months.  Initial data from the Washington University School of Medicine in St. Louis sponsored clinical trial (ClinicalTrials.gov Identifier: NCT05618301) is anticipated in the second half of 2024.

Motixafortide, BioLineRx’s lead therapeutic candidate, was approved by the U.S. Food & Drug Administration (FDA) in September 2023, in combination with filgrastim (G-CSF), to mobilize HSCs for collection and subsequent autologous transplantation in patients with multiple myeloma, under the brand name APHEXDA®.

About SCDSTEMM Clinical Trial with St. Jude Children’s Research Hospital Inc.

The SCDSTEMM (Sickle Cell Disease Stem Cell Mobilization and Apheresis Using Motixafortide) Phase 1 clinical trial is an open-label, multi-center study evaluating the safety, tolerability, and feasibility of single-agent motixafortide (CXCR4 inhibitor) for the mobilization and collection of CD34+ HSCs in 12 patients (aged 18 and older) with SCD.  The trial’s primary objective is to assess the safety and tolerability of motixafortide in SCD patients, as determined by the incidence of adverse events.  Secondary objectives include understanding CD34+ kinetics after motixafortide administration in patients with SCD and determining the number of CD34+ HSCs collected via leukapheresis.  The study is designed in two parts: Part A (N=6) will evaluate single dose motixafortide mobilization followed by one apheresis session; Part B (N=6) will evaluate daily motixafortide administration over a two-day mobilization and apheresis regimen.    Additional objectives include phenotype and cell function characterization, as well as assessment of the gene modifying potential and senescence of CD34+ cells.

About Sickle Cell Disease

SCD is one of the most common genetic diseases globally, affecting millions of people throughout the world and disproportionately impacting persons of color.  SCD arises from mutations in the hemoglobin gene, ultimately leading to the production of abnormally shaped (sickle) red blood cells. The clinical manifestations of SCD include anemia and blood vessel occlusion which can lead to both acute and chronic pain, as well as tissue ischemia across multiple organ systems (e.g., brain, lungs, heart, kidneys, spleen, liver, bones), ultimately compromising end organ function. The cumulative impact of these complications significantly impacts morbidity and mortality for patients with SCD.
