Abstract
BACKGROUND The non-interventional PROPER study generated real-world evidence on clinical outcomes following transition in routine practice from reference adalimumab to the EMA-approved SB5 biosimilar adalimumab in patients with immune-mediated inflammatory disease. METHODS Adults with rheumatoid arthritis (RA), axial spondyloarthritis (axSpA), psoriatic arthritis (PsA), Crohn's disease (CD), or ulcerative colitis (UC) were enrolled at 63 sites across Europe. Eligible patients received ≥ 16 weeks of routine treatment with reference adalimumab before transitioning to SB5, and were followed for 48 weeks post-transition. The primary objective was to evaluate candidate predictors (clinically relevant baseline variables with incidence ≥ 15% by indication cohort) associated with persistence on SB5 at 48 weeks post-initiation. Key primary outcome measures were persistence on SB5 (estimated by Kaplan-Meier methodology) and clinical characteristics and disease activity scores at the time of transition to SB5 treatment (baseline). RESULTS A total of 955 eligible patients were enrolled (RA, n = 207; axSpA, n = 127; PsA, n = 162; CD, n = 447; UC, n = 12), of whom 932 (97.6%) completed follow-up and 722 (75.6%) were still receiving SB5 at week 48. Kaplan-Meier estimates (95% confidence interval, CI) of persistence on SB5 at week 48 for RA, axSpA, PsA, and CD were 0.86 (0.80-0.90), 0.80 (0.71-0.86), 0.81 (0.74-0.86), and 0.72 (0.67-0.76), respectively. The single candidate predictor associated with probability of SB5 discontinuation before week 48 was female sex [RA, axSpA, and CD cohorts; HR (95% CI): 3.53 (1.07-11.67), 2.38 (1.11-5.14), and 2.21 (1.54-3.18), respectively]. Disease activity scores remained largely unchanged throughout the study, with proportions by cohort in remission at baseline versus week 48 being 59.2% versus 57.2%, 81.0% versus 78.0%, 94.7% versus 93.7%, and 84.0% versus 85.1% for patients with RA, axSpA, PsA, and CD, respectively. Similarly, the SB5 dosing regimen remained unchanged for the majority of patients from baseline to week 48, the most common regimen being 40 mg every 2 weeks. In total, 232 patients (24.3%) reported at least one adverse drug reaction, and most events were mild; eight patients (3.9%) in the RA cohort experienced nine serious adverse events (SAEs; two possibly related to SB5); eight patients (4.9%) in the PsA cohort experienced nine SAEs (one possibly related to SB5); 22 patients (4.9%) in the CD cohort experienced 27 SAEs (four possibly related to SB5); and no SAEs were observed in the UC cohort. CONCLUSIONS With the exception of female sex in RA, axSpA, and CD, none of the candidate predictors were associated with SB5 discontinuation. Persistence on SB5 was high, treatment effectiveness was maintained, and no safety signals were detected. TRIAL REGISTRATION This trial is registered with ClinicalTrials.gov: NCT04089514.

Abstract
Transcript therapies using chemically modified messenger RNAs (cmRNAs) are emerging as safe and promising alternatives for gene and recombinant protein therapies. However, their applications have been limited due to transient translation and relatively low stability of cmRNAs compared to DNA. Here we show that vacuum-dried cmRNA-loaded collagen sponges, termed transcript activated matrices (TAMs), can serve as depots for sustained delivery of cmRNA. TAMs provide steady state protein production for up to six days, and substantial residual expression until 11days post transfection. Another advantage of this technology was nearly 100% transfection efficiency as well as low toxicity in vitro. TAMs were stable for at least 6months at room temperature. Human BMP-2-encoding TAMs induced osteogenic differentiation of MC3T3-E1 cells in vitro and bone regeneration in a non-critical rat femoral bone defect model in vivo. In summary, TAMs are a promising tool for bone regeneration and potentially also for other applications in regenerative medicine and tissue engineering.

Abstract
Limitations associated to the use of growth factors represent a major hurdle to musculoskeletal regeneration. On the one hand, they are needed to induce neo-tissue formation for the substitution of a necrotic or missing tissue. On the other hand, these factors are used in supraphysiological concentrations, are short lived and expensive and result in many side effects. Here we develop a gene transfer strategy based on the use of chemically modified mRNA (cmRNA) coding for human bone morphogenetic protein 2 (hBMP-2) that is non-immunogenic and highly stable when compared to unmodified mRNA. Transfected stem cells secrete hBMP-2, show elevated alkaline phosphatase levels and upregulated expression of RunX2, ALP, Osterix, Osteocalcin, Osteopontin and Collagen Type I genes. Mineralization was induced as seen by positive Alizarin red staining. hBMP-2 cmRNA transfected human fat tissue also yielded an osteogenic response in vitro as indicated by expression of hBMP-2, RunX2, ALP and Collagen Type I. Delivering hBMP-2 cmRNA to a femur defect in a rat model results in new bone tissue formation as early as 2 weeks after application of very low doses. Overall, our studies demonstrate the feasibility and therapeutic potential of a new cmRNA-based gene therapy strategy that is safe and efficient. When applied clinically, this approach could overcome BMP-2 growth factor associated limitations in bone regeneration.
