Table 4
Experiment and dose: Matched intramuscular reporter comparison SM-102 LNP versus the other lipid formulations; 1 µg Fluc mRNA in 20 µL IM; female BALB/c mice; n=6/group | Readout and comparator: Readout: 24 h; total photon emission in the injection-site region Comparator: ALC-0315 and cKK-E12 | Result and source: SM-102 produced approximately 60% higher mean reporter signal than ALC-0315/cKK-E12 under the matched conditions; Fig. 1f marks p<0.05 comparisons. Fig. 1e–f; mean ± SEM; one-way ANOVA with Tukey comparisons
Table 4
Experiment and dose: Neutralizing-antibody response Spike-antigen mRNA; 1 µg IM per dose on days 1 and 21; n=10/group | Readout and comparator: Readout: Plasma collected days 14 and 35; pseudovirus-neutralization endpoint Comparator: Other ionizable-lipid comparators at the same helper-lipid composition | Result and source: SM-102 elicited a modest but statistically higher neutralization response than ALC-0315 at both sampling points. All groups increased titers more than 28-fold after boosting. Fig. 2c–f; median Neut50 displayed in violin plots; n=10; no exact Neut50 values extracted
Table 4
Experiment and dose: Inflammatory markers after prime and boost Same IM antigen-mRNA study, 1 µg per dose; n=10/group | Readout and comparator: Readout: Day 2 and day 22, each 24 h after dosing Comparator: Pre-immune plasma and cKK-E12 LNP | Result and source: No significant increase was generally detected for the measured inflammatory panel with SM-102 or ALC-0315 relative to pre-immune plasma. cKK-E12 produced stronger responses for several markers. This is a limited time-point panel, not comprehensive toxicology. Fig. 2b; Supplementary Fig. 1; mean ± SEM
Table 4
Experiment and dose: Sucrose and short freezing exposure SM-102 Fluc mRNA-LNP, PBS ±10% sucrose; held 1 h at 4 °C or frozen at −80 °C then thawed | Readout and comparator: Readout: DLS after storage / thawing Comparator: Same LNP without sucrose | Result and source: Sucrose prevented the broad/multiple particle-size peaks observed after freezing and thawing without sucrose. The experiment does not test 20 repeated freeze–thaw cycles. Fig. 3a–b; Supplementary Fig. 2
Table 4
Experiment and dose: Functional delivery after short storage 1 µg Fluc mRNA in 20 µL IM after the Fig. 3 storage conditions; n=5/group | Readout and comparator: Readout: 24 h after injection Comparator: PBS without sucrose and frozen samples with/without sucrose | Result and source: For refrigerated samples, 10% sucrose increased reporter expression by approximately 30–40%; sucrose preserved functional delivery through the tested freezing–thawing exposure. Fig. 3c–f; mean ± SEM; two-way ANOVA with Sidak comparisons
Table 4
Experiment and dose: Long-term formulated-particle storage SM-102 Fluc mRNA-LNP at 50 µg/mL; 10% sucrose; 4 °C versus −80 °C; 1 µg IM test dose; n=5/group per functional readout | Readout and comparator: Readout: Weeks 0, 4, 8, 12 and 20; mouse imaging 24 h after each test injection Comparator: Week-0 activity and the other ionizable-lipid formulation | Result and source: SM-102 retained activity better than ALC-0315 at 4 °C, but both developed aggregation around week 8 and lost functional activity with prolonged refrigeration. Activity was retained at −80 °C across the tested period. Fig. 4a–d; mean ± SEM; within-group comparisons to week 0
Table 4
Experiment and dose: Encapsulation versus functional stability Same storage study; formulated Fluc mRNA-LNP | Readout and comparator: Readout: Particle/encapsulation monitoring; RNA gel at week 20 Comparator: 4 °C versus −80 °C | Result and source: Encapsulation remained high while refrigerated functional potency declined. Gel analysis showed comparable detectable RNA after 20 weeks at both temperatures; retained encapsulation or RNA band intensity did not guarantee retained delivery activity.
