Mesoblast Limited is an Australian regenerative medicine company. It seeks to provide treatments for inflammatory ailments, cardiovascular disease, and back pain. The company is led by Silviu Itescu, who founded the company in 2004. [1]
In Mesoblast's annual report from August 2010, the company first announced positive results of preclinical trials showing radiographic and pathologic disc regeneration with MPC-06-ID. Mesoblast said they were in the process of completing an Investigational New Drug (IND) submission to the United States Food and Drug Administration to commence Phase 2 clinical trials. [2] In December 2010, Mesoblast entered into an agreement with U.S.-based Cephalon to develop and commercialize novel adult Mesenchymal Precursor Stem Cell (MPC) therapeutics for degenerative conditions of the cardiovascular and central nervous systems. [3]
In September 2011, Mesoblast entered into an agreement with Swiss-based Lonza Group. Under the agreement, Lonza will manufacture the stem cells for Mesoblast's MPC cell products. Mesoblast will also have exclusive access to Lonza's Cell Therapy facilities in Singapore for the manufacture of allogeneic cell therapies. [4] In May 2014, Mesoblast announced it would receive incentives from the Singapore Economic Development Board (EDB) for activities in Singapore related to manufacturing operations, product development, and commercialization. [5] [6]
Osiris Therapeutics, a pharmaceutical company, sold its stem cell business and its related patents to Mesoblast in 2013. [7] [8] In March 2014, Circulation Journal published the results of a clinical trial using MPCs as adjunctive therapy for patients with a Ventricular Assist Device. [9]
On February 10, 2015, Mesoblast was granted a patent by the United States Patent and Trademark Office (USPTO) covering its proprietary Mesenchymal Precursor Cell (MPC) technology for use in the treatment of degenerated intervertebral discs. [10] In June 2015, Mesoblast received $5.8 million from the Australian Government for Research and Development (R&D) activities conducted during the 2014 financial year. The funds were provided to Mesoblast under the Government's R&D Tax Incentive Program. [11]
In February 2016, Mesoblast's licensee, JCR Pharmaceuticals Co., Ltd., began marketing its MSC drug, Ryoncil, under the trade name TEMCELL. The company sold it as an allogeneic cell product for the treatment of acute graft versus host disease (aGVHD) in children and adults in Japan. TEMCELL is the first allogeneic cell therapy to be fully approved in Japan. [12] [13] [14] [15] In December 2016, Mesoblast and Mallinckrodt Pharmaceuticals entered into an agreement to exclusively negotiate a commercial and development partnership for MPC-06-ID in the treatment of chronic low back pain due to disc degeneration. [16] In June 2024, the company resubmitted a Biologics License Application with the FDA Ryoncil (TEMCELL) to treat children with steroid-refractory acute graft-versus-host disease (SR-aGVHD); in July of the same year, the government agency accepted the application. [17] A Phase III clinical trial began enrollment on July 22, 2024, of rexlemestrocel-L for patients with chronic low back pain caused by inflammatory degenerative disc disease. [18]
In December 2024, Mesoblast received regenerative medicine advanced therapy designation (RMAT) from the FDA for its drug Revascor (Rexlemestrocel-L) to treat children with regenerative heart disease. [19] [20]
Mesoblast products are largely derived from its proprietary mesenchymal lineage cells. [21] This includes Mesenchymal Precursor Cells (MPCs) and Mesenchymal Stem Cells (MSCs).
Mesoblast's solution for back pain was criticized by competitor Regenexx in August 2015. Dr. Chris Centeno said the trial results contained confusing and misleading language, press releases for phases 1 and 2 did not include images of MRIs to prove that discs were regenerated and Centeno expressed doubts about mass producing cell quality. He also stated that the host's immune system removes the injected stem cells. [30]
Mesoblast is listed as MSB on the Australian Securities Exchange (ASX), as MESO on the NASDAQ, and as MEOBF on the ATC Markets.
The company reported its financial results in June 2024. [31]
Infliximab, a chimeric monoclonal antibody, sold under the brand name Remicade among others, is a medication used to treat a number of autoimmune diseases. This includes Crohn's disease, ulcerative colitis, rheumatoid arthritis, ankylosing spondylitis, psoriasis, psoriatic arthritis, and Behçet's disease. It is given by slow injection into a vein, typically at six- to eight-week intervals.
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 a patient and produce additional normal blood cells. HSCT may be autologous, syngeneic, or allogeneic.
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.
Degenerative disc disease (DDD) is a medical condition typically brought on by the aging process in which there are anatomic changes and possibly a loss of function of one or more intervertebral discs of the spine. DDD can take place with or without symptoms, but is typically identified once symptoms arise. The root cause is thought to be loss of soluble proteins within the fluid contained in the disc with resultant reduction of the oncotic pressure, which in turn causes loss of fluid volume. Normal downward forces cause the affected disc to lose height, and the distance between vertebrae is reduced. The anulus fibrosus, the tough outer layers of a disc, also weakens. This loss of height causes laxity of the longitudinal ligaments, which may allow anterior, posterior, or lateral shifting of the vertebral bodies, causing facet joint malalignment and arthritis; scoliosis; cervical hyperlordosis; thoracic hyperkyphosis; lumbar hyperlordosis; narrowing of the space available for the spinal tract within the vertebra ; or narrowing of the space through which a spinal nerve exits with resultant inflammation and impingement of a spinal nerve, causing a radiculopathy.
Cell therapy is a therapy in which viable cells are injected, grafted or implanted into a patient in order to effectuate a medicinal effect, for example, by transplanting T-cells capable of fighting cancer cells via cell-mediated immunity in the course of immunotherapy, or grafting stem cells to regenerate diseased tissues.
Stem-cell therapy uses stem cells to treat or prevent a disease or condition. As of 2024, the only FDA-approved therapy using stem cells is hematopoietic stem cell transplantation. This usually takes the form of a bone marrow or peripheral blood stem cell transplantation, but the cells can also be derived from umbilical cord blood. Research is underway to develop various sources for stem cells as well as to apply stem-cell treatments for neurodegenerative diseases and conditions such as diabetes and heart disease.
