Preclinical proof-of-concept in engineered cellular vesicles and mouse tumor models; no human data, no efficacy endpoint with confidence intervals or statistical comparison, and no toxicity data reported.
Early-stage preclinical study demonstrating a novel nanoparticle design in cell culture and a single murine tumor model, without clinical translation, efficacy comparators, or mechanistic validation beyond correlative evidence.
This is a mechanistic and proof-of-concept study demonstrating a novel nanomaterial design principle in cancer cells and a mouse model, but lacks comparative efficacy data, clinical endpoints, or phase-appropriate trial design to support clinical recommendations.
Early-stage in vivo proof-of-concept in a single model system with no control arm comparison, surrogate endpoints, and no clinical translation data reported.
Preclinical animal study of a novel nanoparticle catalyst combined with radiotherapy showing mechanistic activity and tumor inhibition in a single model system, without human data or direct clinical translation evidence.
Preclinical study in obese mice demonstrating proof-of-concept for a novel nanoparticle-hydrogel system; lacks human data, clinical endpoints, and peer-reviewed publication evidence in the provided text.
Single in vivo xenograft model with no comparator arm, surrogate endpoints (tumor growth, calcification), and no clinical data; represents early-stage proof-of-concept for a novel nanoparticle platform.
Preclinical mechanistic study in orthotopic GBM models demonstrating a novel nanoplatform strategy; lacks clinical efficacy data, human trials, or regulatory evidence.
