financial highlights

  • Royalty income from Temcell sales


    HS injection


    Licensee sales in Japan for the quarter increased 36% to $1.9 million from $1.4 million for the quarter ended September 30, 2022.

  • Net cash used from operations in the fourth quarter was $16.5 million. This represents a reduction of USD 1.7 million (9%) compared to the 2022 comparative quarter and represents a reduction of USD 14.1 million (46%) over the 2021 comparative quarter.


  • In December 2022, a fund managed by Oaktree Capital Management, LP (“Oaktree”) will be awarded up to a $90 million five-year facility, subject to the achievement of certain milestones by September. Announced US$30 million in additional funding for Mesoblast. March 30, 2023.

  • Cash on hand at the end of the quarter was US$67.6 million, subject to certain milestones, and up to an additional US$40 million can be drawn from existing lines of credit.

Operational highlights

  • The Biologics License Application (BLA) resubmission dossier for remestemcel-L in the treatment of children with steroid-resistant graft-versus-host disease (SR-aGVHD) has been completed and will be submitted to the FDA soon.

  • Survival outcomes for children or adults with the most severe forms of SR-aGVHD have not improved over the past two decades.


    The lack of approved treatments for children under the age of 12 means that there is an urgent need for treatments that improve children’s dismal survival outcomes.

  • Mesoblast’s pivotal Phase 3 clinical trial (GVHD-001) in children with SR-aGVHD provided long-term survival results for remestemcel-L. Results showed durable survival through 4 years of follow-up. These new long-term survival data are an important factor in our resubmission of her BLA to the FDA.

    This study was conducted by the International Center for Blood and Bone Marrow Transplant Research (CIBMTR) in 51 evaluable children with SR-aGVHD enrolled in a Phase 3 trial across 20 US centers.

    Overall survival in the remestemcel-L cohort was 63% at 1 year, 51% at 2 years, and 49% at 4 years, with a median survival of 2-3 years. A recently published study of children or adults with SR-aGVHD who received best available therapy (BAT) or the only FDA-approved drug for adults, ruxolitinib, had a one-year survival rate of 40 ~49%, with a 2-year survival rate of 25% to 38%. .


  • Mesoblast previously collaborated with the FDA on key endpoints of a pivotal Phase 3 trial of rexlemestrocel-L in patients with chronic low back pain with degenerative disc disease (CLBP). trial.

  • The FDA has confirmed that pain relief for 12 months is an approvable indication, with important secondary measures of improved function and reduced opioid use.

  • Preparations are underway to initiate a pivotal Phase 3 clinical trial by mid-2023.

  • Results from three randomized controlled trials of rexlemestrocel-L in class II/III heart failure with reduced ejection fraction (HFrEF) and end-stage HFrEF with left ventricular assist device (LVAD) demonstrated a common mechanism of action (MOA). support the idea of Thereby, rexlemestrocel-L reverses inflammation-associated endothelial dysfunction and reduces adverse clinical outcomes across a spectrum of HFrEF patients.

  • Improvement in left ventricular ejection fraction (LVEF) at 12 months in HFrEF patients may be a suitable initial surrogate endpoint for long-term reduction in major adverse cardiovascular events (MACE) .

  • Mesoblast plans to meet with the FDA under its existing Regenerative Medicine Advanced Treatment (RMAT) designation to discuss data and evidence of common MOA across the broader HFrEF spectrum, including patients with LVAD.


Full-time executive director salaries were US$324,678 and non-executive director compensation was US$192,164 and are detailed in item 6 of the Appendix 4C Cash Flow Report for this quarter.

About mesoblast

Mesoblast is a global leader in the development of allogeneic (off-the-shelf) cell medicines for the treatment of severe and life-threatening inflammatory conditions. The Company leverages its proprietary mesenchymal cell therapy technology platform to develop late-stage product candidates that respond to severe inflammation by releasing anti-inflammatory factors that counteract and modulate multiple effector arms of the immune system. Established a broad portfolio, resulting in significant declines. of harmful inflammatory processes.

Mesoblast has a strong and extensive global intellectual property portfolio protected until at least 2041 in all major markets. Our proprietary manufacturing process produces industrial-scale cryopreserved off-the-shelf cell medicines. These cell therapies have defined drug release standards and are expected to be readily available to patients worldwide.

Mesoblast is developing product candidates for defined indications based on its remestemcel-L and rexlemestrocel-L allogeneic stromal cell technology platforms. Remestemcel-L is being developed for pediatric and adult inflammatory diseases, including steroid-refractory acute graft-versus-host disease, biologic-resistant inflammatory bowel disease, and acute respiratory distress syndrome. Rexlemestrocel-L is being developed for progressive chronic heart failure and chronic low back pain. Two products have been commercialized in Japan and Europe by his Mesoblast licensees and the company has established commercial partnerships in Europe and China for certain Phase 3 assets.

Mesoblast has offices in Australia, the United States and Singapore and is listed on the Australian Securities Exchange (MSB) and NASDAQ (MESO). For more information, visit, LinkedIn: Mesoblast Limited, and Twitter: @Mesoblast.
