A Systems Pharmacology Model of Aging Identifies Optimal Combination Therapies With Secondary Benefits on Weight Loss and Metabolic Health
What this study shows
A calibrated systems-pharmacology model of aging finds that optimal drug combinations diverge by objective: GLP-1 receptor agonist + SGLT2 inhibitor + metformin is best for metabolic (weight/HbA1c) improvement, while GLP-1 receptor agonist + SGLT2 inhibitor + rapamycin is predicted best for aging-related (frailty/biological-age-gap) benefit — the two goals do not converge on the same regimen. Authors flag the aging predictions as hypothesis-generating, pending external validation.
At a glance
| Evidence type | M Molecular — cells, biochemistry, structure Marked M because it is molecular or in-vitro work (model: Quantitative systems pharmacology (QSP) model calibrated to human trial data (semaglutide STEP trials)) rather than a whole-organism health-outcome study. That is often exactly where causal biology gets established -- the code says which system the finding was shown in, and nothing about how good the work is. |

Extracted findings
These fields were extracted from the paper with AI assistance and have not been checked against the source. Read them as a pointer into the paper, not as curated claims; where they disagree with the curated summary above, the curated summary stands.
| Intervention | Rapamycin, metformin, SGLT2 inhibitors, GLP-1 receptor agonists (combination therapy, in silico) |
| Target | mTOR/aging pathway (rapamycin arm) within a multi-drug QSP model |
| Model | Human (in silico model calibrated to human trial data) |
| Effect | Predicts GLP-1RA+SGLT2i+rapamycin as the optimal combination for aging-related outcomes (frailty, biological age gap), distinct from the best metabolic-outcome combination |
