NEW YORK, June 30, 2021 (GLOBE NEWSWIRE) -- Mesoblast Limited (Nasdaq:MESO; ASX:MSB), global leader in allogeneic cellular medicines for inflammatory diseases, today provided an update on the strategy for bringing rexlemestrocel-L to patients in the United States (US) with chronic low back pain (CLBP) due to degenerative disc disease (DDD) refractory to available therapies, including opioids. Excessive use of opioids in this patient population continues to be a major focus for US healthcare policymakers, regulatory authorities, patients and physicians, with more than 50% of US opioid prescriptions being for the treatment of CLBP.1,6,7
Mesoblast has filed a request and expects to hold a Type C meeting with the US Food & Drug Administration (FDA) during the current quarter to discuss the pathway to US regulatory approval for rexlemestrocel-L following the recently completed 404 patient Phase 3 trial in patients with chronic inflammatory back pain due to degenerative disc disease.
“We look forward to discussing with the FDA the most efficient path forward given the durable pain reduction for at least two years and the opioid-sparing activity from a single administration of rexlemestrocel-L that was observed in the recent Phase 3 trial,” said Dr Fred Grossman, Chief Medical Officer of Mesoblast.
Mesoblast plans to leverage the results from a planned US trial to support potential product approvals in both US and EU by including 20% EU patients in order to provide regulatory harmonization, cost efficiencies and streamlined timelines, without initiating an EU trial. In line with this strategy, Mesoblast and its partner in Europe and Latin America, Grünenthal, have amended their collaboration agreement, with Mesoblast being eligible to receive payments up to US$112.5 million prior to product launch in the EU, inclusive of US$17.5 million already received, if certain clinical and regulatory milestones are satisfied and reimbursement targets are achieved. Cumulative milestone payments could reach US$1 billion depending on the final outcome of Phase 3 studies and patient adoption. Mesoblast will also receive tiered double-digit royalties on product sales as per the original agreement.
About Chronic Low Back Pain due to Degenerative Disc Disease
Chronic low back pain (CLBP) affects approximately 10-15% of the adult population, equivalent to more than 30 million people in the United States and almost 40 million people across the EU5.1 Degenerative disc disease (DDD) causing discogenic pain is the most common etiology of CLBP in adults.4,5 Over 7 million patients in each of the United States and E.U.5 are thought to suffer from CLBP caused by degenerative disc disease,4-6 a disease which involves inflammation and degeneration of the intervertebral discs due to various factors including age, trauma or genetic pre-disposition.
Back pain causes more disability than any other condition and inflicts substantial direct and indirect costs on the healthcare system6, including excessive use of opioids in this patient population. There are few treatment options for patients with CLBP who fail conservative therapy, including opioids, spinal injections and surgery (e.g., spinal fusion or total disk arthroplasty).7 More than 50% of US opioid prescriptions are for the treatment of CLBP,1-3 despite the fact that opioids are associated with serious and potentially life-threatening side effects and have not demonstrated efficacy in the treatment of CLBP.3,8,9 In 2018, more than 67,000 drug overdose deaths occurred in the United States10 of which almost 47,000 (70%) were opioid related.
Mesoblast is a world leader in developing allogeneic (off-the-shelf) cellular medicines for the treatment of severe and life-threatening inflammatory conditions. The Company has leveraged its proprietary mesenchymal lineage cell therapy technology platform to establish a broad portfolio of late-stage product candidates which respond to severe inflammation by releasing anti-inflammatory factors that counter and modulate multiple effector arms of the immune system, resulting in significant reduction of the damaging inflammatory process.
Mesoblast has a strong and extensive global intellectual property portfolio with protection extending through to at least 2040 in all major markets. The Company’s proprietary manufacturing processes yield industrial-scale, cryopreserved, off-the-shelf, cellular medicines. These cell therapies, with defined pharmaceutical release criteria, are planned to be readily available to patients worldwide.
Mesoblast has completed Phase 3 trials of rexlemestrocel-L for advanced chronic heart failure and chronic low back pain. Remestemcel-L is being developed for inflammatory diseases in children and adults including steroid refractory acute graft versus host disease and moderate to severe acute respiratory distress syndrome. Two products have been commercialized in Japan and Europe by Mesoblast’s licensees, and the Company has established commercial partnerships in Europe and China for certain Phase 3 assets.
Mesoblast has locations in Australia, the United States and Singapore and is listed on the Australian Securities Exchange (MSB) and on the Nasdaq (MESO). For more information, please see www.mesoblast.com, LinkedIn: Mesoblast Limited and Twitter: @Mesoblast
