Omidubicel, sold under the brand name Omisirge, is a blood-based cell therapy used for the treatment of blood cancers. [3] Omidubicel is a nicotinamide-modified allogeneic hematopoietic progenitor cell therapy derived from cord blood. [3]
The most common adverse reactions include infections, graft-versus-host disease, and infusion reactions. [3]
Omidubicel is composed of human allogeneic stem cells from umbilical cord blood that are processed and cultured with nicotinamide (a form of vitamin B3). [3] Each dose is patient-specific, containing healthy stem cells from an allogeneic pre-screened donor, meaning it comes from a different individual rather than using the patient's own cells. [3] Omidubicel was approved for medical use in the United States in April 2023. [3] [4]
Omidubicel is indicated for use in people twelve years of age and older with blood cancers (hematologic malignancies) planned for umbilical cord blood transplantation following myeloablative conditioning to reduce the time to neutrophil recovery and the incidence of infection. [3] [4]
The US Food and Drug Administration (FDA) evaluated the safety and effectiveness of omidubicel based on a randomized, multicenter study comparing transplantation of omidubicel to transplantation of umbilical cord blood, in subjects between the ages of 12 and 65 years. [3] The study enrolled a total of 125 participants. [3] All participants in the study had confirmed blood cancers. [3] The efficacy of omidubicel was based on the amount of time needed for recovery of the participant's neutrophils (a type of white blood cell that helps protect the body from infections) and the incidence of infections following transplantation. [3] In total, 125 participants were randomized--62 participants to receive omidubicel-onlv and 63 to the unmanipulated cord blood group. [4] Fifty-two participants were transplanted with omidubicel-onlv receiving a median CD34+ cell dose of 9.0 X 106 cells/kg (range 2.1 – 47.6 X 106 cells/kg). [4] Fifty-six participants were transplanted in the unmanipulated cord blood arm with one or two cord units (66% received two cord units). [4] In the 42 participants with reported post-thaw cell dose, the median CD34+ cell dose was 0.2 X 106 cells/kg (range 0.0 – 0.8 X 106 cells/kg). Multiple conditioning regimens were used, including total body irradiation-based or chemotherapy-based options. [4]
The FDA granted the application for omidubicel priority review, breakthrough therapy, and orphan drug designations. [3] [4] The FDA granted regular approval of Omisirge to Gamida Cell Ltd. [3]
Multiple myeloma (MM), also known as plasma cell myeloma and simply myeloma, is a cancer of plasma cells, a type of white blood cell that normally produces antibodies. Often, no symptoms are noticed initially. As it progresses, bone pain, anemia, kidney dysfunction, and infections may occur. Complications may include hypercalcemia and amyloidosis.
Basiliximab, sold under the brand name Simulect, is a monoclonal antibody used to prevent rejection in kidney transplants. It is a chimeric mouse-human monoclonal antibody to the α chain (CD25) of the IL-2 receptor of T cells. It is used in combination with other medicines used to prevent organ rejection.
Hematopoietic stem-cell transplantation (HSCT) is the transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood in order to replicate inside of a patient and to produce additional normal blood cells. It may be autologous, allogeneic or syngeneic.
Graft-versus-host disease (GvHD) is a syndrome, characterized by inflammation in different organs. GvHD is commonly associated with bone marrow transplants and stem cell transplants.
A cord blood bank is a facility which stores umbilical cord blood for future use. Both private and public cord blood banks have developed in response to the potential for cord blood in treating diseases of the blood and immune systems. Public cord blood banks accept donations to be used for anyone in need, and as such function like public blood banks. Traditionally, public cord blood banking has been more widely accepted by the medical community. Private cord blood banks store cord blood solely for potential use by the donor or donor's family. Private banks typically charge around $2,000 for the collection and around $200 a year for storage.
Cord blood is blood that remains in the placenta and in the attached umbilical cord after childbirth. Cord blood is collected because it contains stem cells, which can be used to treat hematopoietic and genetic disorders such as cancer. There is growing interest from cell therapeutics companies in developing genetically modified allogenic natural killer cells from umbilical cord blood as an alternative to CAR T cell therapies for rare diseases.
Gemtuzumab ozogamicin, sold under the brand name Mylotarg, is an antibody-drug conjugate that is used to treat acute myeloid leukemia.
Maribavir, sold under the brand name Livtencity, is an antiviral medication that is used to treat post-transplant cytomegalovirus (CMV). Maribavir is a cytomegalovirus pUL97 kinase inhibitor that works by preventing the activity of human cytomegalovirus enzyme pUL97, thus blocking virus replication.
Subcutaneous T-cell lymphoma is a cutaneous condition that most commonly presents in young adults, and is characterized by subcutaneous nodules. Common symptoms include fever, fatigue, and pancytopenia.
Daratumumab, sold under the brand name Darzalex, is an anti-cancer monoclonal antibody medication. It binds to CD38, which is overexpressed in multiple myeloma cells. Daratumumab was originally developed by Genmab, but it is now being jointly developed by Genmab along with the Johnson & Johnson subsidiary Janssen Biotech, which acquired worldwide commercialization rights to the drug from Genmab.
Letermovir is an antiviral drug for the treatment of cytomegalovirus (CMV) infections. It has been tested in CMV infected patients with allogeneic stem cell transplants and may also be useful for other patients with a compromised immune system such as those with organ transplants or HIV infections. The drug was initially developed by the anti-infective division at Bayer, which became AiCuris Anti-infective Cures AG through a spin-out and progressed the development to end of Phase 2 before the project was sold to Merck & Co for Phase 3 development and approval.
Betibeglogene autotemcel, sold under the brand name Zynteglo, is a gene therapy for the treatment for beta thalassemia. It was developed by Bluebird Bio and was given breakthrough therapy designation by the US Food and Drug Administration in February 2015.
Venetoclax, sold under the brand names Venclexta and Venclyxto, is a medication used to treat adults with chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), or acute myeloid leukemia (AML).

Lisocabtagene maraleucel, sold under the brand name Breyanzi, is a cell-based gene therapy used to treat large B-cell lymphoma.
Belumosudil, sold under the brand name Rezurock among others, is a medication used for the treatment of chronic graft versus host disease (cGvHD). It is in the class of drugs known as serine/threonine kinase inhibitors. Specifically, it is an inhibitor of Rho-associated coiled-coil kinase 2. Belumosudil binds to and inhibits the serine/threonine kinase activity of ROCK2. This inhibits ROCK2-mediated signaling pathways which play major roles in pro- and anti-inflammatory immune cell responses. A genomic study in human primary cells demonstrated that the drug also has effects on oxidative phosphorylation, WNT signaling, angiogenesis, and KRAS signaling.
Selinexor sold under the brand name Xpovio among others, is a selective inhibitor of nuclear export used as an anti-cancer medication. It works by blocking the action of exportin 1 and thus blocking the transport of several proteins involved in cancer-cell growth from the cell nucleus to the cytoplasm, which ultimately arrests the cell cycle and leads to apoptosis. It is the first drug with this mechanism of action.
Teclistamab, sold under the brand name Tecvayli, is a human bispecific monoclonal antibody used for the treatment of relapsed and refractory multiple myeloma. It is a bispecific antibody that targets the CD3 receptor expressed on the surface of T-cells and B-cell maturation antigen (BCMA), which is expressed on the surface of malignant multiple myeloma B-lineage cells.
