Mesoblast's Ryoncil Nears Potential FDA Approval for Pediatric Graft-versus-Host Disease

  • Mesoblast's remestemcel-L (Ryoncil) has a PDUFA date of January 7, 2025, for treating steroid-refractory acute graft-versus-host disease (SR-aGVHD) in pediatric patients.
  • If approved, Ryoncil would be the first treatment option for children under 12 with SR-aGVHD, addressing a critical unmet need in this vulnerable population.
  • Industry analysts maintain a consensus Buy rating for Mesoblast, with an average price target of $11, representing a 56% upside potential.

Pelareorep Plus Paclitaxel Shows Survival Benefit in HR+/HER2- Breast Cancer

  • The combination of pelareorep and paclitaxel demonstrated a significant improvement in overall survival (OS) compared to paclitaxel alone in patients with HR+/HER2- metastatic breast cancer.
  • In the BRACELET-1 trial, the median OS was not reached in the pelareorep/paclitaxel arm, while it was 18.2 months in the paclitaxel monotherapy arm (HR, 0.48).
  • The 2-year survival rate was 64% in the pelareorep/paclitaxel group versus 33% in the paclitaxel monotherapy group, indicating a substantial survival advantage.
  • Progression-free survival (PFS) also improved with the combination therapy, showing a median PFS of 12.1 months compared to 6.4 months with paclitaxel alone (HR, 0.39).

Biomarkers sNfL and sGFAP Predict Disability Worsening in Multiple Sclerosis

  • A new study identifies serum neurofilament light chain (sNfL) and serum glial fibrillary acidic protein (sGFAP) as key biomarkers for predicting disability worsening in multiple sclerosis (MS).
  • Elevated sNfL levels at MS onset correlate with increased risk of both relapse-associated worsening (RAW) and progression independent of relapse activity (PIRA).
  • High sGFAP levels, combined with low sNfL, indicate an increased risk of PIRA and poor response to current disease-modifying treatments (DMTs).
  • Measuring sNfL and sGFAP levels can enable personalized treatment strategies, optimizing the use of high-efficacy DMTs and identifying patients needing novel therapies.

EMA Finalizes Reflection Paper on Single-Arm Trials for Efficacy Assessment

  • The European Medicines Agency (EMA) has finalized a reflection paper addressing the use of single-arm trials for establishing drug efficacy, providing guidance for pharmaceutical companies.
  • The paper outlines considerations for when single-arm trials may be appropriate, particularly in rare diseases or situations with significant unmet medical needs.
  • It emphasizes the importance of robust data collection, clear endpoints, and rigorous statistical analysis to ensure the reliability of results from single-arm trials.
  • The EMA's guidance aims to harmonize the approach to evaluating single-arm trials, potentially accelerating drug development for conditions with limited treatment options.

Xofluza Significantly Reduces Influenza Transmission in Phase III Trial

  • Roche's Xofluza (baloxavir marboxil) significantly reduced influenza transmission within households in a Phase III trial, marking a potential advance in flu control.
  • The CENTERSTONE study met its primary endpoint, showing a single oral dose of Xofluza reduced the likelihood of household members contracting the virus.
  • The antiviral treatment was well-tolerated, with no new safety signals, suggesting a favorable risk-benefit profile for influenza prevention.
  • These results could improve health outcomes at both individual and community levels, especially for influenza pandemic preparedness.

Five Strategic Travel Solutions to Boost Clinical Trial Diversity and Patient Enrollment

  • Recent CISCRP report identifies travel to study clinics as the primary burden for clinical trial participants, highlighting a persistent barrier to patient enrollment and diversity.
  • Clinical trial sites' locations often exclude minority communities, who are disproportionately affected by certain diseases yet face significant transportation and accessibility challenges.
  • Implementing comprehensive travel support solutions, including coordination services, timely reimbursements, and specialized transport options, can significantly improve trial accessibility and diversity.

Rice and Baylor Receive $2.8 Million to Develop Cell Therapy for ARDS

  • Rice University and Baylor College of Medicine have been awarded $2.8 million by the NHLBI to develop a novel cell therapy for acute respiratory distress syndrome (ARDS).
  • The therapy uses engineered retinal pigment epithelial (RPE) cells to deliver anti-inflammatory cytokines directly to the lungs, reducing inflammation and lung damage.
  • This targeted approach aims to overcome the limitations of current cytokine therapies, such as poor biodistribution, toxicity, and immune complications, in ARDS patients.
  • The collaborative effort seeks to improve patient outcomes by creating cell therapy systems that enhance lung health and increase survival rates for individuals with ARDS.

CheckMate-9ER: Glycoproteomic Analysis Identifies Potential Biomarkers for Nivolumab Plus Cabozantinib in Advanced RCC

• Post-hoc analysis of CheckMate-9ER reveals that higher degrees of fucosylation and sialylation in serum proteins are negative prognostic factors in advanced renal cell carcinoma (RCC). • Serum glycoproteins involved in complement cascade and lipid metabolism may predict response to nivolumab plus cabozantinib versus sunitinib. • High serum levels of CO3 glycopeptide potentially predict favorable response to nivolumab plus cabozantinib, while low levels of CFAH glycopeptide also indicate benefit. • These early exploratory findings suggest protein glycosylation as a potential area for further biomarker development in RCC to predict response to anti-PD-1-based therapy.

Immix Biopharma's NXC-201 Shows Promise in AL Amyloidosis Treatment

  • Immix Biopharma's stock hits a 52-week low amidst market challenges, reflecting investor concerns about the company's financial performance.
  • NXC-201, a CAR-T therapy, demonstrates a 92% overall response rate in an ex-U.S. study for AL Amyloidosis, leading to expansion of U.S. Phase 1b/2 trial.
  • The European Commission grants orphan drug designation to NXC-201 for multiple myeloma, supporting its development for this indication.

Kiromic BioPharma Expands Deltacel-01 Trial for NSCLC to University of Arizona Cancer Center

  • Kiromic BioPharma has activated the University of Arizona Cancer Center as the fifth clinical trial site for its Deltacel-01 Phase 1 trial.
  • The trial evaluates Deltacel™ (KB-GDT-01), an allogeneic gamma delta T-cell therapy, in patients with stage 4 metastatic non-small cell lung cancer (NSCLC).
  • The primary objective is to assess safety, with secondary endpoints including objective response and overall survival in patients who have failed standard therapies.
  • Patient enrollment at the University of Arizona Cancer Center is expected to commence in the coming weeks, expanding the trial's reach.
